Patent DE-19644498-A1 (DE)
Title: Adjustable diaphragm for exhaust-gas flow through catalyser for motor vehicle IC engine
Inventor: KLONDER ARMIN DIPL ING
IPC: F01N3/20
Filed: 1996-10-25
Abstract: An adjustable diaphragm to control the exhaust flow of IC engines has the diaphragm opening limiting the volume flow to a certain part of the flow region of the catalyser. The unused sealed-off region shaded by the diaphragm is thereby conserved. The opening can be changed in its effective cross-sectional area by an actuator. The flow speed of the exhaust in the active part of the catalyser is adjustable by the actuator.  The opening focuses the exhaust volume flow in the starting position upon a heated zone. During the starting process, the exhaust is conducted through the small pre-heated zone and conserves the unheated catalyser part. After the heat-up time of the ignited catalyser, the diaphragm can be extended from the starting position to an operating position since the unheated catalyser part has reached a uniform working temperature by the exhaust heat.

Patent DE-19720835-A1 (DE)
Title: Carburettor with needle controlling mixture
Inventor: DUASO PARDO JAVIER
IPC: F02M5/12
Filed: 1997-05-17
Abstract: The needle (5) is stabilised in the lateral direction in relation to the carburettor jet, minimising friction between them. The holder (6) bears via a washer (13) against the closed bottom (11) of the sleeve (7), which is moved by an actuating wire (9) in opposition to a return spring (10).

Patent DE-19745725-A1 (DE)
Inventor: STENZEL OTTO DR ING
IPC: B22D19/00
Filed: 1997-10-16
Abstract: The invention relates to a method for producing a composite casting part from light metal alloy, especially a cylinder block for an internal combustion engine, with a cast casting body. The inventive method is characterised in that one or several layers of part-melted light metal alloy particles is/are sprayed onto the surface of the casting body, said casting body having been produced in advance. The pulsed mechanical pressure associated with this spraying process destroys an oxide skin which builds up on the surface of the casting body. The displaced oxide particles are absorbed by the layer in such a way that they are spread out. The resulting casting body is then introduced into a mould and cast round with light metal alloy.
Patent DE-19754612-A1 (DE)
Title: Vehicle air conditioner displacement compressor
Inventor: OTA MASAKI
IPC: F04B27/10
Filed: 1997-12-09
Abstract: The coolant gas ejected from the cylinder bores (22a) is received in a collecting space (43) and valve (35) controls the inlet opening to the pressure supply channel (34) so as to control the volume of gas fed from outlet chamber (23b) to the crank chamber (25). This in turn controls the pressure gradient between chamber and the cylinder bores so as to modify the angle of the swashplate (29) accordingly. The valve varies the volume of coolant gas passed from crank chamber via passage (40) to the intake chamber (23a) depending on opened extent of the supply channel to obtain the pressure gradient and plate angle as specified. The collecting space lies in the annular outlet chamber as fitted in the outer section of the housing and is defined by the chamber walls. The space has its own outlet (47) to eject compressor gas.
