Patent DE-4239792-A1 (DE)
Title: Plastic or metal work pieces dried by hot air jet below flame point of cleaning agent - facilitates cleaning and drying of complex shape with minimum energy requirement.
Inventor: HAEGELE HERBERT
IPC: F26B21/08
Filed: 1992-11-26
Abstract: In a process and assembly to clean and/or dry the surface of an object which has been subjected to a cleansing agent, the novelty is that the surface is dried by a medium which is heated to a temp. below that of the flame point of the cleaning agent, applied at high pressure through a jet onto the surface of the object as this is held in a chamber, that the cleaning agent and drying medium are sucked from the chamber into a radiator, that the cleaning agent condenses, and that the drying medium is then reheated to the previous temp. and re-used for the same process. The drying medium is a knife-shaped air jet less than 48 degrees. C. introduced at a speed of at least 15 m/s. Work pieces are rotated or shaken during drying, and are inserted or removed from the drying chamber by a jack. The cleaning agent is a paraffin hydrocarbon or an alcohol. USE/ADVANTAGE - The process and assembly are suitable for removing oil grease or emulsion residues from the surface of metal or plastic components before further operations. Oil residues etc. can be removed efficiently from relatively complex shapes with min. energy requirement. Further the cleaning agent can easily be removed from the drying agent and components do not suffer from distortion from treatment.

Title: Process for the continuous performance of exothermic reactions in a fixed-bed circulation reactor
Inventor: ROSCHKA ERHARD DR
IPC: B01D53/88
Filed: 1992-11-28
Abstract: A process is proposed by which it is possible to generate a circulating reaction zone in a fixed-bed circulation reactor even under unfavourable conditions and to maintain it with minimal operating costs. This is achieved by the gas stream being led off from the fixed-bed circulation reactor in the start-up phase downstream of the reactor section and upstream of the heat exchanger section. A minimisation of operating costs is possible by reduction or avoidance of the volume of catalyst in the circulation line and by using catalytically active static mixers. The use of static mixers has the advantage that a flow virtually free of dead space is generated, the heat transfer in the heat exchanger section is improved and the pressure drop is decreased. The process is particularly suitable for the autothermal treatment of exhaust gases or exhaust air having low contents of gaseous pollutants and/or low loadings of combustible organic dusts and/or fluid particles. An improvement of the gasification of the organic dusts can be achieved by additional feed of oxygen into the exhaust air stream used.

Title: Semiconductor device mfr. e.g. for ridge waveguide semiconductor laser prodn.
Inventor: KANENO NOBUAKI
IPC: H01S5/323
Filed: 1992-12-02
Abstract: After the epitaxial growth of a first semiconductor layer on a semiconductor substrate, an insulating film structure is formed on the layer. Sections of the first semiconductor layer are removed by wet etching, using the insulating film structure as a mask in order to maintain a land with a reversed mesa shape. Then opposite end sections of the insulating film structure are etched away to match the insulating film structure to the width of the land. Then a second semiconductor layer is epitaxially grown on opposite sides of the land, and a third semiconductor layer is epitaxially grown on the land and the second semiconductor layer.

A horizontal support blade (1), which extends in sideward direction of the channel, is located immediately behind the grating in direction of flow. It is tangential to the axial direction of the sleeves.

Title: Detection for the conversion of nitrate into nitrite - uses 1,3-phenylene di-amine in a biological sample, useful in the food and sanitary industry
Inventor: SAVEL JAN DIPL ING
IPC: G01N33/12
Filed: 1993-09-20
Abstract: In the detection method, a biological sample is grown in the presence of 0.01-10 g/l. 1,3-phenylene diamine (1,3 PD) or its salts at a temp. of 1-70 deg.C for up to 14 days and its absorbence is then determined photometrically or by visual examination. The sample may already contain nitrates or they may be added with the growth medium. Pref. the pH is optimal and the growth is in the presence of nutrients and/or microbial growth factors e.g. amino acids and peptone. 1,3-PD does not significantly inhibit microorganisms or their enzymes. The nitrites formed bind to 1,3-PD creating an easily identifiable light-absorbent component. The absorbence can be measured at 450 nm. USE/ADVANTAGE - The determn. of nitrites which are hazardous to health is essential in the food industry or in the health sector. Selective growth media for the detection of nitrite producing bacteria can be produced. The invention can be used in microbial and enzyme tests for the determn. of a nitrate content. In contrast to the present method, current methods use reagents which influence the nitrite formation. Additionally, they are more expensive and cumbersome.
