Dräger was born in the village of Howe (now part of Kirchwerder, Bergedorf, Hamburg. In 1889, Bernhard's father and Carl Adolf Gerling founded ''Firma Dräger und Gerling'' in Lübeck to exploit industrial gas technology. In 1902, Heinrich took Bernhard into partnership, and the firm's name was changed to ''Drägerwerk Heinr. und Bernh. Dräger''. The firm specialised in self-contained breathing sets for industrial and rescue workers and for divers, and welding and cutting torches. The company still exists today, as Drägerwerk AG.

With around 217,000 inhabitants, Lübeck is the second-largest city on the German Baltic coast and in the state of Schleswig-Holstein, after its capital of Kiel, and is the 35th-largest city in Germany. The city lies in Holstein, northeast of Hamburg, on the mouth of the River Trave, which flows into the Bay of Lübeck in the borough of Travemünde, and on the Trave's tributary Wakenitz. The city is part of the Hamburg Metropolitan Region, and is the southwesternmost city on the Baltic, as well as the closest point of access to the Baltic from Hamburg. The port of Lübeck is the second-largest German Baltic port after the port of Rostock. The city lies in the Northern Low Saxon dialect area of Low German.

The term characteristically refers to a powerful entrepreneur or investor who controls, through personal enterprise ownership or a dominant shareholding position, a firm or industry whose goods or services are widely consumed. Such individuals have been known by different terms throughout history, such as industrialists, robber barons, captains of industry, czars, moguls, oligarchs, plutocrats, or taipans.

Bergedorf
Bergedorf () is the largest of the seven boroughs of Hamburg, Germany, named after Bergedorf quarter within this borough. In 2020 the population of the borough was 130,994. History The city of Bergedorf received town privileges in 1275, then a part of the younger Duchy of Saxony (1180–1296), which was partitioned by its four co-ruling dukes in 1296 into the branch duchies of Saxe-Lauenburg and Saxe-Wittenberg. Bergedorf then became part of the former. This was only to last until 1303, when Lauenburg's three co-ruling dukes, Albert III, Eric I, and John II partitioned their branch duchy into three smaller duchies. Eric then held Bergedorf (Vierlande) and Lauenburg and inherited the share of his childless brother Albert III, Saxe-Ratzeburg, after he was already deceased in 1308 and a retained section from Albert's widow Margaret of Brandenburg-Salzwedel on her death. However, his other brother, John II, then claimed a part, so in 1321 Eric conceded Bergedorf (with Vierlande ...

Industrial Gas
Industrial gases are the gaseous materials that are manufactured for use in industry. The principal gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium and acetylene, although many other gases and mixtures are also available in gas cylinders. The industry producing these gases is also known as industrial gas, which is seen as also encompassing the supply of equipment and technology to produce and use the gases. Their production is a part of the wider chemical Industry (where industrial gases are often seen as "specialty chemicals"). Industrial gases are used in a wide range of industries, which include oil and gas, petrochemicals, chemicals, power, mining, steelmaking, metals, environmental protection, medicine, pharmaceuticals, biotechnology, food, water, fertilizers, nuclear power, electronics and aerospace. Industrial gas is sold to other industrial enterprises; typically comprising large orders to corporate industrial clients, covering a size range fr ...

Self-contained Breathing Apparatus
A self-contained breathing apparatus (SCBA), sometimes referred to as a compressed air breathing apparatus (CABA) or simply breathing apparatus (BA), is a device worn to provide breathable air in an atmosphere that is immediately dangerous to life or health. They are typically used in firefighting and industry. The term ''self-contained'' means that the SCBA is not dependent on a remote supply of breathing gas (e.g., through a long hose). If designed for use under water, it is also known as a Scuba set (self-contained underwater breathing apparatus). When not used underwater, they are sometimes called industrial breathing sets. Unofficial names include ''air pack'', ''air tank'', ''oxygen cylinder'' or simply ''pack'', which are mostly used in firefighting. An SCBA typically has three main components: a high-pressure tank (e.g., , about 150 to 374 atmospheres), a pressure regulator, and an inhalation connection (mouthpiece, mouth mask or face mask), connected together and mou ...

Oxy-fuel Welding And Cutting
Principle of burn cutting Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the United States) and oxy-fuel cutting are processes that use fuel gases (or liquid fuels such as gasoline or petrol, diesel, bio diesel, kerosene, etc) and oxygen to weld or cut metals. French engineers Edmond Fouché and Charles Picard became the first to develop oxygen-acetylene welding in 1903. Pure oxygen, instead of air, is used to increase the flame temperature to allow localized melting of the workpiece material (e.g. steel) in a room environment. A common propane/air flame burns at about , a propane/oxygen flame burns at about , an oxyhydrogen flame burns at and an acetylene/oxygen flame burns at about . During the early 20th century, before the development and availability of coated arc welding electrodes in the late 1920s that were capable of making sound welds in steel, oxy-acetylene welding was the only process capable of making welds of except ...

Patent Application
A patent application is a request pending at a patent office for the grant of a patent for an invention described in the patent specification and a set of one or more claims stated in a formal document, including necessary official forms and related correspondence. It is the combination of the document and its processing within the administrative and legal framework of the patent office. To obtain the grant of a patent, a person, either legal or natural, must file an application at a patent office with the jurisdiction to grant a patent in the geographic area over which coverage is required. This is often a national patent office, but may be a regional body, such as the European Patent Office. Once the patent specification complies with the laws of the office concerned, a patent may be granted for the invention described and claimed by the specification. The process of "negotiating" or "arguing" with a patent office for the grant of a patent, and interaction with a patent offic ...
