Title: Prodn. of adhesive for glass plates - by pumping e.g. resin and hardener from tanks to intermediate containers and then to mixer by synchronised pumps to hold proportions
Inventor: LENHARDT KARL
IPC: B29B7/60
Filed: 1989-09-06
Abstract: Two pastes, used as the components of a seal and adhesive to bond glass plates together, are continuously fed in set proportions from their containers to a nozzle.

Title: Circular saw for cutting stone blocks - is brought to rest when driving torque falls below specified minimum value
Inventor: KRESTEL ERICH DIPL ING
IPC: B23Q15/007
Filed: 1989-12-29
Abstract: The stone black (1) is cut into smaller pieces by a circular saw (4) driven by an electric motor. The saw is moved to and fro across the block with the depth of cut increasing with each reversal of direction. The direction of travel is reversed by limit switches (6,7) mounted at each end of the saw travel. The motor is stopped when the required driving torque falls below a specified minimum. Since the motor operates at constant speed and constant voltage, the motor torque is directly proportional to the motor current so the motor is stopped when the current falls below specified minimum value. USE - Circular saws for cutting stone blocks.

Title: Electronic switching system for electromechanical relay - uses series electronic switch for interrupting DC voltage to provide periodic DC pulses
Inventor: SCHWALM UWE DIPL ING
IPC: H01H47/32
Filed: 1990-03-05
Abstract: The DC switching system uses periodic DC pulses applied to the relay, with the length of the pulses modulated in dependence on the relay current, to prevent the max. relay current being exceeded. The relay current drops in the pauses between the DC pulses with a time constant which is greater than  the pulse period. Pref. the DC voltage is switched via an electronic switch in series with the relay coil, with the relay current through the electronic switch measured to allow the switch to be blocked when a given relay current is reached, the current diverted through a shunt path in parallel with the relay coil. ADVANTAGE - Reduced power losses.

Filed: 1990-03-06
Abstract: The spring (1) has a relatively broad base (2) from which two lateral prongs (5, 6) project further than the central prong (7) so that they pass through holes in the circuit board (19) for soldering to conductive sections (20) on its far side.$  The central prong (7) abuts against the near side of the board (19). The narrowing of the spring towards its prongs leaves a space for an electronic component (22) between two neighbouring springs.$  USE/ADVANTAGE - For e.g. programmer of domestic electrical appliance. Springs can be mass-produced and assembled automatically in accordance with each application.
