Trademark
A trademark (also written trade mark or trade-mark) is a type of intellectual property consisting of a recognizable sign, design, or expression that identifies products or services from a particular source and distinguishes them from others. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher, or on the product itself. Trademarks used to identify services are sometimes called service marks. The first legislative act concerning trademarks was passed in 1266 under the reign of Henry III of England, requiring all bakers to use a distinctive mark for the bread they sold. The first modern trademark laws emerged in the late 19th century. In France, the first comprehensive trademark system in the world was passed into law in 1857. The Trade Marks Act 1938 of the United Kingdom changed the system, permitting registration based on "intent-to-use", creating an examination based process, an ...

Translation Memory
A translation memory (TM) is a database that stores "segments", which can be sentences, paragraphs or sentence-like units (headings, titles or elements in a list) that have previously been translated, in order to aid human translators. The translation memory stores the source text and its corresponding translation in language pairs called “translation units”. Individual words are handled by terminology bases and are not within the domain of TM. Software programs that use translation memories are sometimes known as translation memory managers (TMM) or translation memory systems (TM systems, not to be confused with a Translation management system (TMS), which is another type of software focused on managing process of translation). Translation memories are typically used in conjunction with a dedicated computer assisted translation (CAT) tool, word processing program, terminology management systems, multilingual dictionary, or even raw machine translation output.

TM-83 Mine
The TM-83 is a Soviet off-route shaped charge anti-tank mine, first shown publicly in 1993, and developed in 1983. The mine consists of a large Misznay Schardin effect warhead and is actived using its infra-red and seismic sensors. Deployment The mine can be installed on soil, or be attached to various objects only manually. The mine is generally positioned 5 meters from the road, and it is intended to attack and aimed using an integrated sight. The TM-83 can be deployed in two operation modes – autonomous or controlled. The primary difference is that the controlled version has a 100-meter-long wire attached, allowing the operator to switch it through its various modes repeatedly (safe or active, see ). If the mine is controlled, it can be switched to its safety mode and be easily removed; however, if the mine is in its autonomous mode, it is considered impossible to remove due to the high sensitivity of the seismic sensor and the chance that the mine will be set off by the ...

TM-62 Series Of Mines
The TM-62 is a Soviet anti-tank blast mine made in many variants. It has a central fuze and typically a explosive charge, but the variants vary greatly in detail. The mine can be laid manually or automatically from a mine laying machine including the PMR-1, PMR-2 wheeled towed mine layers, the GMZ-3 tracked mine laying vehicle and the VMR-2 helicopter mine laying system. The TM-62 can be fitted with the same fuzes as the TM-72, which include MVN-72 and MVN-80 fuzes which are vibration and magnetism sensitive. In a static test, the TM-62M proved capable of penetrating the hull of a Centurion tank, killing the simulated crew of animals inside. The mine was used in the 2022 Russian invasion of Ukraine where Ukrainian civilians helped to clear the mines from roads. Variants * TM-62M, with a circular metal case. It is the most widely employed variant. * TM-62B, with a paper or cardboard case, basically a block of cast explosive with a fuze set into the center. * TM-62D, with a wo ...

TM-57 Mine
A TM-57 with a tilt-rod fuze The TM-57 mine is a large, circular Soviet metal-cased blast anti-tank mine. It can either be triggered by a pressure or a tilt-rod fuze. A development of the TM-46 mine, it is found in Africa, the Middle East, and South East Asia. Description The TM-57 has a larger main charge and improved fuzing compared to the earlier TM-46. It is circular with a metal case and a central fuze well. A secondary pull-action fuze ''MUV-2'' ( Rus. МУВ-2) or ''VPF'' ( Rus. ВПФ) pull and tilt fuze can be fitted on the side of the mine, which serves as an anti-handling device. The tilt rod fuze gives the mine improved resistance to blast; it is activated when it is forced to a deflection of 25 to 30 degrees. A training version of the mine that produces smoke is designated the TM-60. Specifications *Diameter: 316 mm *Height: 102 mm *Operating pressure: 120–400 kg or 21 kg tilt. *Weight: 8.47 kg *Explosive content: 6.34 kg of TNT, TGA (RDX/TNT/Aluminium) or MS ...

TM-46 Mine
The TM-46 mine is a large, circular, metal-cased Soviet anti-tank mine. It uses either a pressure or tilt-rod fuze, which is screwed into the top. Anti-tank mines with this type of fuze were capable of inflicting much more damage to armored vehicles, when compared to a typical AP mine. Because the TM-46 has a metal casing, it is very easy to detect with a metal detector. However, mine-fields containing TM-46s may have also been sown with minimum metal mines, e.g. the PMA-2. Combat Use The mine was used by the North Vietnamese forces during the Vietnam War, and is found in many countries in Africa, the Middle East and South East Asia. Action MVM-583 fuze The MVM-583 is a mechanical pressure fuze. The activation pressure of this fuze is 140 kf. It comprises a striking mechanism, safety pin and the MD-6N shock tube detonator. Upon a vehicle driving over a TM-46 mine equipped with this fuze, the lid of the mine deforms along with the fuze. Upon further deformation, the ...

TM-41 Mine
The TM-41 was a circular, metal-cased Soviet anti-tank landmine used during the Second World War. The mines case consisted of a short cylinder with the entire top surface being used as a pressure plate. The mine has a carrying handle on the side of the mine. It was normally painted olive drab and was broadly similar to the larger, later, TM-44 mine. The mine could be waterproofed with washers and laid underwater, where it can remain operational for two months. Pressure on the pressure plate resulted in lock balls being force out of position, releasing a striker, which triggers a detonator, then a booster and then the mines main charge. The mine was used with anti-handling devices. A Chinese copy of the mine was also produced. Specifications * Diameter: 254 mm * Height: 140 mm * Weight: 5.4 kg * Explosive content: 3.9 kg of Amatol or TNT Trinitrotoluene (), more commonly known as TNT, more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC nam ...

TM 65 Mine
The TM 65 (Telamiina 65) is a circular Finnish minimum metal anti-tank blast mine. It is broadly based on the Russian ''TM-62 mine''. The mines body is made from a thin shell of fibreglass Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass clo ... over a cast block of explosive, with a central fuze well that holds the pressure fuze. The original ''TM 65'' used a ''US-65'' fuze as used in the ''SM-65 anti-personnel mine'', the later TM 65 77 uses a pressure fuze similar to the Russian ''MV-5'' fuze called ''Painesytytin 77''. The fuze is covered with a plastic pressure plate, giving it an activation pressure of 150 to 300 kg. However, if this is not installed, the mine will activate with a pressure of a few kg. The mine also has a secondary fuze well on the side for the installation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transverse Mode
A transverse mode of electromagnetic radiation is a particular electromagnetic field pattern of the radiation in the plane perpendicular (i.e., transverse) to the radiation's propagation direction. Transverse modes occur in radio waves and microwaves confined to a waveguide, and also in light waves in an optical fiber and in a laser's optical resonator. Transverse modes occur because of boundary conditions imposed on the wave by the waveguide. For example, a radio wave in a hollow metal waveguide must have zero tangential electric field amplitude at the walls of the waveguide, so the transverse pattern of the electric field of waves is restricted to those that fit between the walls. For this reason, the modes supported by a waveguide are quantized. The allowed modes can be found by solving Maxwell's equations for the boundary conditions of a given waveguide. Types of modes Unguided electromagnetic waves in free space, or in a bulk isotropic dielectric, can be described as a super ...

Transition Metal
In chemistry, a transition metal (or transition element) is a chemical element in the d-block of the periodic table (groups 3 to 12), though the elements of group 12 (and less often group 3) are sometimes excluded. They are the elements that can use d orbitals as valence orbitals to form chemical bonds. The lanthanide and actinide elements (the f-block) are called inner transition metals and are sometimes considered to be transition metals as well. Since they are metals, they are lustrous and have good electrical and thermal conductivity. Most (with the exception of group 11 and group 12) are hard and strong, and have high melting and boiling temperatures. They form compounds in any of two or more different oxidation states and bind to a variety of ligands to form coordination complexes that are often coloured. They form many useful alloys and are often employed as catalysts in elemental form or in compounds such as coordination complexes and oxides. Most are strongly param ...

Thulium
Thulium is a chemical element with the symbol Tm and atomic number 69. It is the thirteenth and third-last element in the lanthanide series. Like the other lanthanides, the most common oxidation state is +3, seen in its oxide, halides and other compounds; however, the +2 oxidation state can also be stable. In aqueous solution, like compounds of other late lanthanides, soluble thulium compounds form coordination complexes with nine water molecules. In 1879, the Swedish chemist Per Teodor Cleve separated from the rare earth oxide erbia another two previously unknown components, which he called holmia and thulia; these were the oxides of holmium and thulium, respectively. A relatively pure sample of thulium metal was first obtained in 1911. Thulium is the second-least abundant of the lanthanides, after radioactively unstable promethium which is only found in trace quantities on Earth. It is an easily workable metal with a bright silvery-gray luster. It is fairly soft and slowly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
