Title: Plasticising and injecting screw coupling - permits axial adjustment and prevents axial play between drive shaft and screw
Inventor: ECKERT HELMUT
IPC: B29C45/17
Filed: 1973-07-14
Abstract: An injection moulding machine has the plasticising screw coupled to the drive shaft by a torque-transmitting and axial-force-transmitting coupling; the end of one shaft penetrates into an axial passage in the end of the other shaft and is keyed there against relative rotation, e. g. by a splined shaft coupling. The axial force is transmitted by longitudinally-tightened coupling components which, when pulled tightly together, force the end of the inner shaft against a replaceable adjustment disc seated in the blind axial passage in the outer shaft, so that there is no axial play between the shafts. The thickness of the disc is selected to give the required depth of penetration of the one shaft end into the other. Axial adjustment, to give the exact desired forward limiting position of the screw during injection, is possible. There is no axial play, causing damage to the abutting surfaces.

Title: Loudspeaker with capacitive diaphragm movement feed-back - enables the signal-to-noise ratio to be increased using voltage divider
Inventor: BACKES WOLFGANG
IPC: H04R3/00
Filed: 1974-03-19
Abstract: The sound signal voltage is applied to one of the capacitive pickup electrodes. In order to compensate the pickup capacitance, the signal amplitude is a function of frequency. The resistor (R1) in parallel with the capacitor (C) is related to the high value earthing resistor (RO) and the pick-up capacity (CO) by the equation R1/RO = (approx.)

Title: Battery supervision system for infrequently used circuits - which automatically tests remaining charge and operating time
Inventor: LAASS HEINZ
IPC: H01M10/42
Filed: 1975-01-10
Abstract: The application is to circuits powered by primary or secondary cells, typically emergency lights or alarm installations, and removes the need for testing by an operator. Additional circuits comprise a timer, solid state switch for a load, and voltage measuring components from which the charged state is automatically assessed. If the remaining charge is inadequate for the designed duty a continuous alarm is initiated. Typically the battery is subjected to an impulse load current equal to the design load, and the charge evaluated during the impulse. The impulse frequency may be set as desired. Normally the drain due to the impulses represents only a few ampere-minutes per year.
