Patent DE-19826785-A1 (DE)
Title: Combined service and hand brake for cars
Inventor: KANT BERNHARD
IPC: F16D65/14
Filed: 1998-06-16
Abstract: A combined service and hand brake for cars has at least one combined wheel brake (1) that is controlled and used not only for service braking but also for hand braking. The clamping force of the wheel brake (1) in the case of hand braking is generated by an activation energy source present inside the service brake installation with an electromechanical or electromechanically operated locking device (6) which is able to fix the wheel brake in the clamping state. The locking device can be switched by an electrical control unit between a position with locking activated and a position with locking deactivated. The locking device is fixed in current-free fashion by spring force or magnet force in the respective locking position.

Title: Control system for internal combustion engine
Inventor: ZHANG HONG DR
IPC: F02D41/02
Filed: 1998-07-24
Abstract: The control system promotes rapid heating up of the catalytic converter (19) in the exhaust system (12) of an internal combustion engine (10). The catalytic converter is of the three-way type and there is a lambda sensor (18) immediately upstream of it. The lambda sensor is connected to a microcomputer (20) with a data memory (23). There are sensors mounted on the engine to measure the coolant temperature (22) and the rotational speed (N) of the engine. The induction tract (11) contains an airflow sensor (13), a throttle valve (14) and a fuel injector (15). When the engine is stopped the internal resistance of the lambda sensor and its temperature are recorded. These values are measured again when the engine is restarted. The time during which the engine has been stopped is recorded. These values are used to calculate the start-up temperature of the catalyser and modify the catalyser warm-up procedure accordingly.

Patent DE-19911090-A1 (DE)
Title: Automatic coffee machine that can supply batches of varying quantities and qualities
Inventor: PULVERMUELLER PETER
IPC: A23F5/26
Filed: 1999-03-12
Abstract: The machine comprises a boiler (5) a brew chamber (6), a storage vessel (8) a dispensing nozzle (9) and connecting piping and valves. The brew chamber (6) consists of a cylinder whose drive can move it to cover pistons so that it is closed at both ends during the brewing cycle. Ground coffee is fed into the chamber in the open position. The cylinder is then raised to cover piston and hot water is fed via line (11a) and spring-loaded, normally closed, non-return valve, which can be held open by piston. The coffee passes through sieve and line (15) as the pistons move towards each other. Initially this coffee is recycled through the chamber to remove fine grounds through the grounds already built up on the sieve. Then coffee can be passed into the storage vessel or directly to a cup. The original gap between the movable pistons will determine the size of the batch. Thus batches between one liter and one cup can be provided. If pressurized coffee, for espresso, is required the piston is raised during the recycling so that liquid can then be forced into the chamber by forcing the piston down at the end of the cycle. Used grounds are removed as piston projects slightly over the upper edge of cylinder when it is lowered to leave an accessible gap between the pistons. A control unit for the steering and control of the cycle, a coffee mill, coffee containers and means of passing ground coffee to the chamber, or removing it, are clearly required but not shown.

The power transmission element and the shaft have axially and mutually movable lockable and unlockable locking elements (42,44,46) on at least one axial position between the swivel axle and the join between the power transmission element and movable grip. The locking elements lock the shaft and power transmission element across the lengthwise direction of the shaft.
