Title: Optical light guide cable - with fibre strands laid slack in chambers of elastic star shaped core during mfr.
Inventor: NOBIS ERICH DR
IPC: G02B6/44
Filed: 1975-04-26
Abstract: An optical light guide cable consists of a star-like carrier core which contains a number of light guide strands between the radial ribs, and an outer sheath. The carrier core is elongated within the elastic range before the optical light guide strands are inserted into the parallel chambers. Shortly afterwards the tension is relaxed so that the strands now lie in slight undulations. This ensures that mechanical stresses are applied to the light guide strands neither during the manufacture nor in service. The resulting cable is very flexible, yet no flexural stress is transmitted to the light guide strands. The carrier element is easy to extrude.

Title: Switch-on noise suppression - is performed in television integrated audio stage circuit using damping circuit with zener diode
Inventor: KLEIN RUDOLF
IPC: H03F3/187
Filed: 1975-09-25
Abstract: The audio circuit consists of a single integrated chip (15) to which a potentiometer (13) volme control (14) signal is fed, and from which a loudspeaker (47) is driven through a capacitance (16). A feedback loop (through another capacitance (18) is also incorporated. The 25 volt supply to the circuit is applied through a filter or smoothing network containing an external capacitance (20) and another capacitance (22) resistance (21) smoothing network. The effect of this is to produce a slow initial voltage increase after switch-on, followed by a sharp impulse (28) when the certain circuit thresholds are crossed. By including a zener diode (25) and a further resistance in the smoothing network, a smooth and noise free voltage growth (29) can be guaranteed.
