Plunger
A plunger is a device driven by or against fluid pressure. In plumbing, the term plunger commonly refers to handheld tools used to clear blockages in drains and pipes. Plumbing plungers consist of a rubber suction cup attached to a stick (''shaft'') usually made of wood or plastic. A different bellows-like design is usually constructed of plastic. Alternate names for plumbing plungers include ''force cup'', ''plumber's friend'' or ''plumber's helper''. In musical performance, tools called plungers are used to mute trumpets and trombones. A plunger may also refer to a component of a device that generates fluid flow, such as in a medical syringe or a French press coffee brewer. History The plumbing plunger was invented in 1874 by New York confectioner John Hawley, with the flattened rim added in 1876. The invention is referred to in the patent as a "vent-clearer", and was marketed as a "force cup". Applications Plumbing Use For the common plunger, the cup is pus ...

Plunger (hydraulics)
A plunger is a Cylinder, cylindrical rod used to transmit Hydraulics, hydraulic compression force. It is characterized by its length being much greater than its diameter, and it is thus distinguished from a regular piston (where the working surface is larger than the thickness of the rod, i.e. more like a Disk (mathematics), disk). They are mainly used as part of certain types of pumps and hydraulic machines. Plungers are used for Fluid mechanics, fluid-mechanical power transmission in pumps (Plunger pump, plunger pumps), Hydraulic transmission, hydraulic gearboxes, high-pressure diesel Injection pump, injection pumps, Hydraulic press, hydraulic workshop presses and Jack (device), jacks, and other equipment, and are distinguished in fluid mechanics by being a piston without moving seals. The seals are instead located in the wall through which the plunger slides (as opposed to Piston ring, piston rings on a piston). Plungers are often supplied with a suitable stationary plunger bus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mute (music)
A mute is a device attached to a musical instrument which changes the instrument's timbre, tone quality (timbre) or lowers its volume. Mutes are commonly used on string instrument, string and brass instruments, especially the trumpet and trombone, and are occasionally used on woodwinds. Their effect is mostly intended for artistic use, but they can also allow players to practice discreetly. Muting can also be done by hand, as in the case of palm mute, palm muting a guitar or grasping a Triangle (music), triangle to dampen its sound. Mutes on brass instruments are typically inserted into the flared end of the instrument (bell). They can also be held in front of or clipped onto the bell. Of brass mutes, the "straight mute" is the most common and is frequently used in classical music, classical and jazz music, but a wide variety are available. On string instruments of the violin family, mutes are usually attached to the bridge (instrument), bridge, the piece of wood that supports t ...

French Press
A French press, also known as a cafetière, ''cafetière à piston'', ''caffettiera a stantuffo'', press pot, coffee press, or coffee plunger, is a coffee brewing device, although it can also be used for other tasks. The earliest known device was patented in 1852 in France by Jacques-Victor Delforge and Henri-Otto Mayer. Name In English, the device is known in North America as a ''French press'' or ''coffee press''; in United Kingdom, Britain and Ireland as a ''cafetière'', after the brand, ''La Cafetière''; in New Zealand, Australia, and South Africa as a ''coffee plunger'', and coffee brewed in it as ''plunger coffee''. In Italian, it is known as a ; in German as a ', ' ("stamp pot"), ', ' ("coffee press") or '; in French as ', or simply as ' (also the usage in Dutch), though some speakers might also use Generic trademark, genericized trademarks, such as Melior or Bodum. Design history Over the years, the French press has undergone several design modifications. The f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trombone
The trombone (, Italian, French: ''trombone'') is a musical instrument in the Brass instrument, brass family. As with all brass instruments, sound is produced when the player's lips vibrate inside a mouthpiece, causing the Standing wave, air column inside the instrument to vibrate. Nearly all trombones use a telescoping slide mechanism to alter the Pitch (music), pitch instead of the brass instrument valve, valves used by other brass instruments. The valve trombone is an exception, using three valves similar to those on a trumpet, and the superbone has valves and a slide. The word "trombone" derives from Italian ''tromba'' (trumpet) and ''-one'' (a suffix meaning "large"), so the name means "large trumpet". The trombone has a predominantly cylindrical bore like the trumpet, in contrast to the more conical brass instruments like the cornet, the flugelhorn, the Baritone horn, baritone, and the euphonium. The most frequently encountered trombones are the tenor trombone and bass tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plopper
The American animated television series ''The Simpsons'' contains a wide range of minor and supporting characters like co-workers, teachers, students, family friends, extended relatives, townspeople, local celebrities, and even animals. The writers intended many of these characters as one-time jokes or for fulfilling needed functions in the town of Springfield, where the series primarily takes place. A number of these characters have gained expanded roles and have subsequently starred in their own episodes. According to the creator of ''The Simpsons'', Matt Groening, the show adopted the concept of a large supporting cast from the Canadian sketch comedy series ''Second City Television''. This article features the recurring characters from the series outside of the five main characters (Homer, Marge, Bart, Lisa and Maggie Simpson). Each of them are listed in order by their first name.

Plumber's Snake
A plumber's snake or drain snake or drain auger is a slender, flexible auger used to dislodge clogs in plumbing. The plumber's snake is often reserved for difficult clogs that cannot be loosened with a plunger. It is also sometimes called a toilet jack. A plumber's snake is often used by plumbers to clear a clogged drain pipe or sanitary sewer. Auger varieties Plumber's snakes have a coiled ( helix-shaped) metal wire with a broader gap between the coils at the terminal end. The operator turns a crank to rotate the helix as it moves through the pipe. If the clog is caused by a dense, but shreddable obstacle, such as tree roots or glass wool, the auger might break it up enough to enable flow. A small, lightweight obstruction might be snagged or corkscrewed by the auger, enabling the operator to pull it away. As the auger cable rotates, it also flails against the interior walls of the pipe, scraping off minerals and oil. Hand auger / hand spinner Hand augers are useful for cl ...

Plumbing
Plumbing is any system that conveys fluids for a wide range of applications. Plumbing uses piping, pipes, valves, piping and plumbing fitting, plumbing fixtures, Storage tank, tanks, and other apparatuses to convey fluids. HVAC, Heating and cooling (HVAC), Sewerage, waste removal, and Drinking water, potable water delivery are among the most common uses for plumbing, but it is not limited to these applications. The word derives from the Latin for lead, ''plumbum'', as the first effective pipes used in the Sanitation in ancient Rome, Roman era were lead pipes. In the developed world, plumbing infrastructure is critical to public health and sanitation. Boilermakers and pipefitters are not plumbers although they work with piping as part of their trade and their work can include some plumbing. History Plumbing originated during ancient civilizations, as they developed public baths and needed to provide drinking water, potable water and sewerage, wastewater removal for large ...

Syringe
A syringe is a simple reciprocating pump consisting of a plunger (though in modern syringes, it is actually a piston) that fits tightly within a cylindrical tube called a barrel. The plunger can be linearly pulled and pushed along the inside of the tube, allowing the syringe to take in and expel liquid or gas through a discharge orifice at the front (open) end of the tube. The open end of the syringe may be fitted with a hypodermic needle, a nozzle or tubing to direct the flow into and out of the barrel. Syringes are frequently used in clinical medicine to administer injections, infuse intravenous therapy into the bloodstream, apply compounds such as glue or lubricant, and draw/measure liquids. There are also prefilled syringes (disposable syringes marketed with liquid inside). The word "syringe" is derived from the Greek σῦριγξ ('' syrinx'', meaning "Pan flute", "tube"). Medical syringes Medical syringes include disposable and safety syringes, injectio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Force
In physics, a force is an influence that can cause an Physical object, object to change its velocity unless counterbalanced by other forces. In mechanics, force makes ideas like 'pushing' or 'pulling' mathematically precise. Because the Magnitude (mathematics), magnitude and Direction (geometry, geography), direction of a force are both important, force is a Euclidean vector, vector quantity. The SI unit of force is the newton (unit), newton (N), and force is often represented by the symbol . Force plays an important role in classical mechanics. The concept of force is central to all three of Newton's laws of motion. Types of forces often encountered in classical mechanics include Elasticity (physics), elastic, frictional, Normal force, contact or "normal" forces, and gravity, gravitational. The rotational version of force is torque, which produces angular acceleration, changes in the rotational speed of an object. In an extended body, each part applies forces on the adjacent pa ...

Drain Cleaner
A drain cleaner, also known as drain opener, refers to a person, device, or product used to unblock sewer pipes or clear clogged wastewater drains. This term typically applies to chemical, enzymatic, or mechanical tools such as commercial chemical cleaners, plumber's snakes, drain augers, bio-enzyme solutions, or toilet plungers. In some contexts, it may also refer to a plumber or professional who specializes in drain cleaning and maintenance. Chemical drain cleaners, plungers, handheld drain augers, and air burst drain cleaners are typically used to address clogs in single drain, such as sinks, toilets, tubs, or shower drains. These tools are effective at removing soft obstructions like hair and grease that accumulate near the drain inlet. However, excessive use of chemical drain cleaners can lead to pipe damage. In contrast, enzymatic drain cleaners rely on natural enzymes to break down organic matter such as grease, hair, and food particles, offering a more environmentally fr ...
