Patent DE-3939899-A1 (DE)
Inventor: SCHALDACH MAX PROF DR ING
IPC: A61N1/36
Filed: 1989-11-29
Abstract: A controlled-rate, artificial cardiac pacemaker (14) comprises a module (12) for adapting the stimulation rate to the patient's actual physical load. In the case of limited or non-existent activity, the output signal of a sensor (10, 11) for the patient's activity status constitutes a control signal for a circuit (20) which reduces the energy supplied to the module for adapting the stimulation rate of the artificial cardiac pacemaker to the patient's actual physical load.

Title: Plush or carpet loom drive mechanism - incorporates synchronous drive to jacquard and loom with release to separate drives and braking system for fault finding
Inventor: JOST GUNTER DIPL ING
IPC: D03D51/02
Filed: 1989-12-19
Abstract: A loom drive mechanism, partic. for plush and carpet looms, with controlled induction coupled motors, and in the event of a disconnection, disc brakes are applied, when the loom and jacquard can be driven separately.  It is arranged that the separate drives can be cross connected to run synchronously, and this disengages and dynamic brakes are applied when the power is cut off. USE - In the event of a weaving fault, equipment on the loom disrupts the power, but the loom and jacquard continue to run by kinetic energy, and have to be brought back in slow motion, or manually, to regain the pattern. The present system stops over-run, start-up is quicker, and there is a saving in power when running.

Title: Electronically controlled hydrostatic transmission for vehicle - has fail-safe switching to one gear ratio if servo pressure fails
Inventor: MANN EGON
IPC: F16H47/04
Filed: 1990-04-02
Abstract: The equipment is driven by a hydraulic motor (3) and planetary gear box with at least two ratios.  At least two control clutches (12, 13) operate the gearbox and one of the clutches is linked to a leak-free line.  This ensures that if the pressure from the hydraulic pump (21) falls below a set level the gear control (23)  to a set ratio and sufficient pressure is held to ensure the vehicle can be driven to safety. The leak-free hydraulic connection holds the respective clutch for long enough to allow the vehicle to be driven to a safe place.  When the servo pressure falls below a second level the transmission is disconnected from the motor, with the main drive pump set into neutral. ADVANTAGE - Failsafe transmission for utility vehicle.
