Title: Supercharger for vehicle IC engine - uses exhaust gases to drive bladed double rotor to compress air variably
Inventor: KICKBUSCH ERNST DIPL ING
IPC: F01C1/077
Filed: 1979-03-21
Abstract: The supercharger for an internal combustion engine uses a combined rotary and oscillating action. The exhaust gases drive a double rotor while expanding which compresses the fresh air sucked in. The rotor has radial blades which form cells which change their volume in a sequence which allows the combustion gases to expand. This change in volume is controlled by two concentric shafts which are connected with elliptical gearwheels or a crank drive which give the periodic change in volume. Where elliptical gearwheels are used double gearwheels are mounted on spindles rotating around central gearwheels and supported inside an oscillating cage. They drive one set of blades to expand the exhaust gases with another set of blades alongside on the same drive shaft to compress the fresh air.

Title: Interactive video text telephone communication system - transmits audio commentary during intervals between consecutive picture frame transfers
Inventor: STREHL HERBERT DIPL ING
IPC: H04M11/08
Filed: 1980-06-09
Abstract: Specific frames may be requested by the subscriber over the telephone through code transmission. As picture data are held in a recirculator store to produce a steady image there is ample channel capacity for supplementing the visual information by an audible one. Pref. two buffer stores are used - one for video data (BT) and another for compressed digitised audio data (bt). During video intervals the latter is clocked out at a bit rate of 1.2 k bits p.s. and passed after digit-to-analogue conversion over the switch (TtU) to the telephone exchange (FeVSt) and from there to the individual subscriber (Tln). The analogue data can be used directly in a loudspeaker whereas the video data - at appropriate moments determined by the code controlled switch (UTt) - convert the slow analogue signals into digital signals for entry into a buffer store (BT Dec) where they are recoded for t.v. use and recirculated to produce a steady image.

Title: Interconnection between main control desk and unattended units - uses ring made of optical links to eliminate interference
Inventor: KNIPP DIETER
IPC: G02B6/28
Filed: 1980-07-17
Abstract: The application is to control and supervisory equipment, for example for a remote controlled switching station. At a main control desk, instructions are sent out to, and incoming signals received from, a number of unattended control or monitoring units. The connection between the equipment is normally in the form of a ring or bus. To eliminate the risk of electromagnetic or capacitative interference with signals passing between units, it is proposed that optical signals travelling through light guides should be used. A typical connector (4) for coupling a light guide ring main to a cubicle comprises two light interfaces (11). The ring main (3) is connected to one side, and to the other two guides, one through connection (8) and one (9,10) into the equipment. Mixing of the signals (12) occurs in the interface (11) to give the series characteristic required.
