Title: Pump system for operating pump installations comprising a plurality of pumps
Inventor: BOHN H DIPL PHYS
IPC: F04B49/02
Filed: 1988-01-15
Abstract: The invention relates to a pump system for operating pump installations comprising a plurality of pumps operated in parallel with the interposition of non-return flow devices, especially for water supply by means of pressure booster installations. The object of the invention is to provide a pump system in which, at all times, the minimum number of pumps required is employed in the optimum operating range of each pump and in the event of output (performance) requirements in intermediate ranges only the smallest pump of the system, at that particular time, is controlled continuously by means of a speed controller. According to the invention, the pumps are to be designed for identical delivery heads, but different outputs at the operating points, the outputs, starting from the pump having the smallest output, being graded in ascending order in a geometric series, and the total capacity required being controlled between zero and the maximum available capacity of the pump system by one or more pumps being brought onstream (cut in) or taken offstream (cut out).

Title: Rotational speed sensor for the anti-block system (stop control system) of motor vehicle brakes
Inventor: ARNOLD JOHANN
IPC: G01P1/00
Filed: 1988-01-28
Abstract: The magnetic core of the rotational speed sensor cooperates with a ring gear (annular gear) which is attached to the wheel hub or the brake drum and serves as a pulse generator (pulse transmitter, pulser). In order to facilitate and accelerate the assembly and adjustment of the sensor, its housing is inserted into a sleeve and secured thereto. In order to set the distance between the magnetic core and ring gear, an annular projection which is provided with an edge (knife edge) is arranged on the housing concentric with the end of the magnet core projecting from the housing, and projects beyond said end and serves as a stop.

Patent DE-3838922-A1 (DE)
Inventor: HIROI MASAKAZU
IPC: B27F7/38
Filed: 1988-11-17
Abstract: A sheet stapling apparatus includes stapling device for stapling a set of sheets, a load detecting device for detecting a level of a load of said stapling device upon stapling operation thereby, and signal generating device for generating a signal when the load detected by said load detecting device is outside a predetermined range. When the resistance experienced by a sheet stapler is too high a signal is generated. An excess resistance signal reverses the staple driving motor. A low resistance signal is interpreted as the absence of a staple (e.g. after fitting a new staple magazine) and repeats the operations of the staple feeding and driving means without advancing the sheets. Resistance to stapling is detected by measuring the current through the drive motor or the speed or acceleration of a member moving with the staple driver. <IMAGE>

Title: Electronic controller for carbon filter for diesel engine - has programmed temperature control to burn off carbon
Inventor: KIRSTEIN GERHARD
IPC: F01N9/00
Filed: 1989-09-04
Abstract: The action of the carbon filter is controlled by a microcomputor (30) which regulates the temperature of the filter w.r.t. the dynamic conditions of the engine. The programmed temperature is compared with the temperature of the exhaust gases leaving the engine, to operate an integral electric heating element if the temperature can be raised. This burns off the carbon without affecting engine performance. The control system has a failsafe mode to operate the burn-off at preset intervals when the automatic control has dropped  out and an emergency system operates. ADVANTAGE - Efficient carbon burn-off without affecting peak torque demands.
