Title: Operating voltage stabilising cct. - designed esp. for line end stage of TV receiver
Inventor: GOSEBERG WALTER DIPL ING
IPC: H04N3/185
Filed: 1974-03-05
Abstract: In instruments such as TV receivers it is frequently necessary to stabilise the DC voltage for operating which is gained from rectifying the network voltage. The circuit proposed for this stabilisation has a regulated amplifying element in the path of the operating current and a resistance switched in parallel with it. The resistance is selected to be effective with voltages which are too high or too low, since it is voltage-dependent and comprises a PTC resistance or an incandescent bulb. Alternatively, both may be used in series. Where the circuit is used to stabilise the operating voltage for a TV set line end stage transistor, the voltage dependent resistance is parallel to a transistor controlled by the modified voltage.

Title: Strong spherical granules of active alumina - produced from alumina hydrate with addn of carbon, long-chain aliphatic cpds and clay
Inventor: KUHRT WINFRIED DR
IPC: B01D53/86
Filed: 1974-07-26
Abstract: Strong spherical granules of active alumina are prepd. by granulating a mixt. of an aluminium oxide hydrate (opt. preliminary dehydrated and ground) and carbon with addn. of an ammonia soln.; drying the granules; heating them at 250-500 degrees C; and finally calcining at 1000-1200 degrees C. The granulation is carried out with addn. of long-chain aliphatic cpds. and/or clay. The granular alumina can be impregnated with a catalyst soln. and used as a mobile catalytic bed; the mechanical strength and abrasion resistance of the granules is very high. The addn. of the long-chain aliphatic cpds. diminished the width of the particle size spectrum, whilst the ave. size can be adjusted to the reqd. value by known methods. The addn. of clay improves the workability of the mixt. of starting matls., reduces the bulk density of the prod. (by 0.15-0.20 kg/l) and increases its specific surface area (by 30-70 m2/g).
