Title: Interlock control circuit for tape recorders - has interlock control logic to provide operational mode control
Inventor: CAP HEINRICH
IPC: H03K19/21
Filed: 1979-08-23
Abstract: The interlock circuit is arranged so that signals are generated relating to the record mode (X) and the start or pause operator (7). The record signal is processed by an inverter (N100) to provide an input to an AND-gate (U1).

Title: Mfg. composite profiles of metal rails with cast foam insulation - for construction of frames for windows, doors etc.
Inventor: PFEIFFER JUERGEN
IPC: E06B1/32
Filed: 1979-10-12
Abstract: Composite profiles involving a pair of metal rails sepd. by a cavity bridged by >=1 metal strips and partly infilled by a cast insulating material are made using equipment which leads the rails beneath a nozzle which discharges the foaming resin between the rails to partly fill the gap, then dispenses a metal strip to bridge the rails at an intermediate level before a second nozzle deposits a further layer of foam on top of the strip. Used for making stiff complex profiles for constructing frames for windows, doors, facades, etc. Use of injection cast insulating material is faster and cheaper for prefabrication of profiles than assembly of insertion of a succession of prefabricated.

Title: Valve in petrol engine starting plug channel - is opened by camshaft with coincidental lack of pressure to allow passage of compressed fuel mixture
Inventor: FRACKE KARL DR
IPC: F02B19/02
Filed: 1979-11-08
Abstract: The channel hot plug ignition aid is for a petrol driven i.c. engine with a valve (6) between the combustion chamber (1) and the channel (4) where the plug (5) is fitted. The valve has to be opened by the camshaft (7) in order for the plug to ignite, which coincides with the flow of compressed fuel/air mixture in the pressureless channel. The camshaft which controls the ignition timing can be automatically turned backwards and forwards for early or delayed ignition. The valve only closes at the commencement of the suction stroke so that combustion gases are removed from the channel during the thrust stroke, leaving the channel pressureless when it closes.

Title: Switch section mounted on square spindle - is self sprung, with contact carrying arm tilted between two sets of fixed contacts
Inventor: LORSBACH PAUL ING GRAD
IPC: H01H1/20
Filed: 1980-08-20
Abstract: The switch with multiple switching sections mounted along a square section spindle has each section mounted on a plate and with an arm mounted on the spindle. This has a rounded nose between two corners which are forced against an L shaped tilting contact carrying arm so as to swing it between two operating positions. The corner of the contact carrying arm rests in a V shaped groove at the end of a bearing sleeve housing a spring. When the arm is tilted so that its contacts are moved into and out of engagement with fixed contacts, it operates against the force of this spring. Thus each switch section contains its own spring system. The two parts of the contact carrying arm are at an angle of 90 degrees, and act after the operating arm has swung through an angel of 75 degrees.
