Title: Supply and starting circuit for discharge lamp - has function generator producing rising control signal for current in lamp with arc discharge and incandescent cathode
Inventor: KLEIN ERWIN DR ING
IPC: H05B41/392
Filed: 1979-06-15
Abstract: The supply and starting circuit has a function generator (6) actuated when the lamp supply (1) is switched on and producing a signal (w) for the setting element (2) that regulates the lamp current. This signal increases from an initial starting value to a final normal-running value. The shape and duration of the signal is matched to the lamp so as to give the longest lifetime. The final value of the signal is set by a reference generator (5). The signal and the lamp current (I) are passed as control variables to the controller (7) that controls the setting element. Lifetime is increased whilst reducing the delay between lighting-up and switching on.

Title: Friction drive for sweeping machines - has switchable coupling allowing delayed start of fan and thus lower starting moment for brush roller
IPC: A47L11/22
Filed: 1979-10-04
Abstract: The switch-on coupling such as a centrifugal force coupling is provided between the friction drive and the blower of the sweeper machine so that when the machine is started up the fan can at first be switched off and only the brush roller driven. This ensures that the starting moment is considerably reduced owing to the much smaller masses to be accelerated. As soon as the machine is accelerated to a certain speed the blower driven can be switched on without problem since the torque required for driving the brush roller has dropped considerably. Switching on the blower at a later moment is no disadvantage since there is hardly any dust drawn in at the very moment of starting up the machine.

Title: Heating system for motor-vehicle - controls hot water flow by motor-driven, speed-dependent valve
Inventor: POROD HELMUT
IPC: F24D19/10
Filed: 1980-02-21
Abstract: This heating system uses a motor-driven valve which circulates and mixes hot and cold water from the engine cooling system in order to provide an efficient control of heat even with an idling or stationary engine. The opening of the principal valve is made dependent on the speed of an electric motor, although manual adjustment is also possible. The variable-speed motor (8) drives via a shaft (9) a valve assembly (13,14) the floating section (13) being rotated relative to the fixed section (14) which is attached to the shaft, depending on the speed of the motor. This rotation varies the openings (15) in the outer section (13) and thus controls the circulation of the hot water. The resulting change of pressure controls another valve (34) that admits cooled water.
