Title: Telephone multiplex equipment with pulse amplitude modulation - superimposes audible signals onto speech without using modulator
Inventor: SILBER MANFRED ING GRAD
IPC: H04Q11/04
Filed: 1978-06-20
Abstract: The receiver (APE) receives signal pulses from the bus bar (SS) at its input (SE). The capacitor (C), controlled by clock pulses (tan), stored the signal pulses thus providing at the output (SA) a replica of the original speech signal. A gate (G) allows a second pulse (Psig) also to control the capacitor charge/discharge cycle. This appears to the subscriber as a click whose tone and pitch can be varied. Thus audible signals directed to a specific subscriber can be superimposed on speech, in TDM systems employing pulse amplitude modulation. The need for modulators for this purpose can be avoided.

Title: Reciprocating yarn guide - has a tube segment as the slide riding in spiral grooves of the drive shaft
Inventor: POPPINGHAUS WINFRIED
IPC: B65H54/28
Filed: 1978-12-22
Abstract: To give a reciprocating movement to the yarn guide on a bobbin winding machine, there is a slide riding in the groove of a drive cylinder following two counter spiral paths. The slide is a tubular segment with an outer dia. equal to or greater than the outer dia. of the grooved shaft and the inner dia. equal to or greater than the dia. of the shaft at the base of the engraved grooves. The slide width corresponds to the groove width so that there is an easy sliding movement with little free play. The ends are rounded by half the tube segment radius so that the inner and outer radii pass over the rounded ends where there are round studs with a dia. matching the slide width, and a length equal to or less than half the difference between the diameters of the drive shaft at its surface and at the groove base. The design ensures that there is minimum loading at the change-over points as the yarn guide follows its reciprocating path.
