Title: Coating of a thermally stressed magnesium or magnesium alloy
IPC: C23C28/02
Filed: 1988-10-27
Abstract: The invention relates to a coating of a thermally stressed magnesium or magnesium alloy. The formation of intermetallic phases is prevented by means of a diffusion barrier, the elements of the diffusion barrier being selected such that they have a certain solubility in the base material. This leads to a kind of sealing which prevents the formation of intermetallic phases under thermal stresses. The diffusion barrier is in turn a functional layer, for example in the event of corrosion, or it is the base of a proper functional layer which is specially adapted to the intended use, for example as heat insulation, or is an anti-wear layer or a protective layer against hot-gas corrosion.

Inventor: KURZ GERMAN
IPC: C10K1/04
Filed: 1989-12-16
Abstract: A process for the cooling of CO rich synthesis gasses uses a previously cooled gas stream for mixing and heat exchange with the hot gas stream. Gas leaving the system passes to a heat exchanger. After the heat exchanger part of the gas stream only leaves the system, the remainder is pref. returned to cool gas leaving the synthesis gas producer. Hot gas from a synthesis gas producer (1) is fed by a line (2) into a compartment (3) of the mixing chamber (4). Cool gas from the heat exchanger (12) is fed by line (7) into a chamber (8) of the mixing chamber (4). Mixed hot and cool gases exit from the compartment (6) of the mixing chamber (4) and pass through the heat exchanger (12) to exit from the system by line (13). Within the mixing chamber (4) two perforated plates (5) and (10) form barriers through which the opposing gas streams flow. The perforations in the plates (5) and (10) may be round or slit shaped. The perforations in each plate are offset from each other. USE/ADVANTAGE - Gasification of solid fuels. Energy savings.

Patent DE-4018180-A1 (DE)
Title: Specified pipe bending with rated angle and radius
Inventor: RAPP HEINRICH
IPC: B21D7/14
Filed: 1990-06-07
Abstract: The bending a pipe or tube through a given angle with a given radius starts with bending at the required radius through the given angle and then allowing for the spring-back.  The spring-back angle is measured and the tube bent through an additional angle equal to the spring-back. This operation may be repeated, if necessary, to determine the additional angle through which the tube must be finally bent.  The value of the additional angle for each different bending angle for each different dia. tube of different material is noted and filed.  The data can then be used to reduce the trial operations, when bending similar tubes in the future.

Title: Adjustable bar feed chuck for automatic lathes - has locking pegs preventing collet rotation machined from solid on conical surface of collet
Inventor: WELLER HANS-MICHAEL
IPC: B23B31/20
Filed: 1990-08-16
Abstract: The outer cylindrical sleeve (11) of the barfeed chuck has a screwthread (13) at one end for attachment to the barfeed. The other end is inserted the inner collet (12) which has a threaded end allowing it to be screwed in or outer of the sleeve (11). Immediately behind the land (32), at the collet nose, is a taper fitting into a matching taper in the sleeve mouth, so that the grip on the bar to be fed can be adjusted by rotating the  collet. The compliance of the sleeve and collet is achieved by slots (15) in the relatively stiff sleeve and slots (21) in the relatively compliant collet. The collet is locked against rotation by rectangular pegs (24) protruding from the collet and engaging the slots (15) of the sleeve. The pegs are simply machined from the solid and  generally follow the conical surface of the collet nose. A cup-ended key (36) is pushed onto the land (32) to close the empty collet, thus disengaging the pegs and allowing the collet to be adjusted. ADVANTAGE - Reliable locking of collet. Longer chuck life. Simple, easy-to-produce design.
