Title: Locking clutch arrangement
Inventor: LANGE DIETER
IPC: B60N2/90
Filed: 1996-05-21
Abstract: The clutch arrangement includes a clutch section on an output shaft side (3) and an input shaft side (2), which engage in a casing (1; la, 1b) with a surrounding brake area. A clamping element (4; 4'; 4") contacts with a part of its outside surface area elastically with the brake area, and introduces a force in the casing at a torque over-load of the output shaft side, in such way, that the clutch arrangement blocks. The brake area comprises two ring surface areas (1c; 1d) arranged in an angle to a plane (E) proceeding vertically to the rotation axis (10), whereby the ring surface areas approach each other with increasing distance from the rotation axis. The part of the outside surface area of the clamping element adjacent the brake area is tapered towards its outside.

Title: Injection moulding machine and energy saving operation of this machine
Inventor: LUDWIG FRANZ JOSEF
IPC: B29C45/76
Filed: 1996-05-31
Abstract: In a process for driving an injection moulding machine with a hydraulic arrangement(1) including a hydraulic pump(2) driven by an asynchronous main drive motor(10), the cooling phase is determined prior to the start of an injection cycle and it is then determined whether this duration is longer than a minimum duration below which switching off of the main drive during the cooling phase no longer saves energy. If the cooling phase duration is above the minimum level the main drive motor(10) is switched off after or at the beginning of the cooling phase of a cycle and switched on again before the start of the opening phase.     A claimed injection moulding machine for the process has a hydraulic power arrangement(1) with an asynchronous main drive motor(10) and a material feeding device, e.g. the rotating machine screw, powered by an additional asynchronous motor.

Patent DE-19631974-A1 (DE)
Title: Vane type fluid pump or motor
Inventor: KEY ALLAN W
IPC: F04C2/344
Filed: 1996-08-08
Abstract: The inner edges of the vanes, which lie inside the rotor, form pressure areas inside the rotor. These areas are pressurised via a compensating channel (32). This compensating channel is located in one side of the housing and is so arranged that the pressurised areas under the vanes are under intermediate pressure when the vanes pass through the stage in which their direction of travel is reversed. The amount of intermediate pressure is dependent on the system pressure. The pressure is controlled by a slide valve (35) which is integral with the housing. The slide valve maintains a constant pressure ratio between the system pressure and the intermediate pressure.
Patent DE-19638135-A1 (DE)
Title: Foot-actuated brake lights for vehicle
Inventor: HUBER FRANZ
IPC: B60Q1/44
Filed: 1996-09-18
Abstract: The vehicle brake-light system is improved by including a flasher circuit which is activated when the brake pressure is above a first set level. As the brake pressure is increased to higher levels the flashing rate increases accordingly, warning the following drivers of strong braking. The low rate of flashing can be about 1 Hz while the highest rate of flashing can be up to 20 Hz. The braking effort is determined by direct measurement of the brake fluid pressure, the pressure on the brake pedal or by the retardation rate of the wheels. A separate flashing brake light (10) can be mounted over the conventional brake light (11), or both effects can be incorporated into one brake light.
