Patent DE-19528900-A1 (DE)
Title: Reciprocating piston steam engine operating method
Inventor: KURPIERS CHRISTIAN
IPC: F01K21/02
Filed: 1995-08-05
Abstract: The steam condenser is used to heat the fresh air delivered into the compression chamber between the piston and cylinder.  A nozzle (1) injects pre-heated water into the compression chamber when this is at maximum compression, causing the water to evaporate. The water can be pre-heated in the nozzle, being injected into a trough formed in the piston. The air can be heated in an intake bend preceding the compression chamber, using as heater coil, combustion chamber or heat-exchanger, and the engine can operate on a two- or four-stroke cycle. Output can be varied by altering the amount of water injected.

Title: Theft protection for motor vehicles
Inventor: FRIEDRICH FERDINAND DIPL PHYS
IPC: B60R25/04
Filed: 1995-09-05
Abstract: The method involves granting access to the vehicle using the transmission of a key code between an electronic key and a controller contg. an immobiliser which checks the code. At least one user dependent parameter of the vehicle is defined and associated with at least one limit value. The current value of the parameter is determined and compared with the limit value(s). For additionally checking access rights the owner must transfer a legitimate secret code to a theft-related controller at least by the time that the limit value is reached. If the secret code is verified correctly the limit value(s) is or are respecified and access is granted.
Patent DE-19534222-A1 (DE)
Title: Brake pedal braking force booster for motor vehicle servo brakes
Inventor: GRAEBER JOHANNES
IPC: B60T13/72
Filed: 1995-09-15
Abstract: The control valve of the brake servo is linked to the brake pedal by the telescopic linkage in which the two sections (10,11) are held together by an integral spring (12). This spring provides a safety support to prevent the brake pedal moving if eg. the driver traps his foot under the pedal while the brake servo is operated via the solenoid control. The integral spring is under compression to hold the two linkage sections at a fixed setting. Alternately the two sections are pulled together by a tensile spring. A simple spring fitting is obtained by using a spiral spring.

Patent DE-19538519-A1 (DE)
Title: Pleating machine e.g. for paper, plastics
Inventor: ZUR NIEDEN ERICH DR
IPC: B65H45/20
Filed: 1995-10-05
Abstract: The machine produces pleats of selected amplitude in a variety of materials fed through the machine in a continuous process. The pleating action is generated by pleating blades (7,8) fitted to support beams (5,6) whose fold and tilt actions are driven by directly coupled servomotors. This dispenses with mechanical cams and enables the pleating pattern to be changed simply by altering the program of the processor control. At least three servo motors are used for the pleating action. The material is fed to the pleating process by a height adjustable table which can be driven by another servomotor, also linked to the processor. The pleated material is fed between two adjustable spacing guide plates, driven by yet another servomotor. The use of low inertia motors provides an active pleating control.
Patent DE-19540009-A1 (DE)
Title: Welding bolts or similar items to workpiece
Inventor: FRANZ UDO PROF DR
IPC: B23K9/20
Filed: 1995-10-27
Abstract: As the ignition point (12) of a bolt or a similar item contacts the workpiece surface and the capacitor discharge is initiated, the resultant welding current locally evaporates the ignition point, and an electric arc is formed between the bolt and the workpiece surface. After this the bolt is joined with the molten phase of the workpiece. The individual constituents of the welding process i.e. ignition, welding and joining are adapted to the material-dependent parameters of the bolt and the workpiece. In partic., the welding process is greatly influenced by the electric resistance of the ignition point. This resistance is a function of the bolt material and the point geometry. Mathematical expressions are derived for the point diameter (d) and its length (l), with (d) less than or equal to (l).

Patent DE-19632550-A1 (DE)
Inventor: HESCH ROLF PROF DR
IPC: B60R21/04
Filed: 1996-08-13
Abstract: The interior of the passenger compartment of a motor vehicle is provided on its outer limiting surfaces with heat insulating materials, preferably to such an extent that a complete heat insulation is achieved. Such a complete heat insulation makes considerable weight and energy savings possible when using heating and/or air conditioning systems in vehicles, and a corresponding reduction of pollutant emissions. The ecological effect of this measure is particularly reinforced if renewable raw materials are used as heat insulating materials, either alone or combined with plastics into composite materials in the individual areas of the motor vehicle. By appropriately designing and sizing the heat insulating measures, they can also lead to additional improvements as regards weight, mechanical stability and sound insulation, besides the actual heat insulating effect, substantially improving the usability and ecological compatibility of the motor vehicle.
