Title: Telephone line signal regeneration circuit - has coupled pulse generators with counter stages used to trigger monostable to provide regenerative pulse
Inventor: CARRUBA ANGELO
IPC: H03K5/156
Filed: 1977-05-17
Abstract: A switching circuit for carrier frequency telephone systems provides pulse regeneration for handling errors in signal transmissions. The input signal line (1) is coupled to two pulse generating circuits (CK1, CK2) with an inverter stage (I). The pulse generator outputs are coupled to counters of predetermined lengths (C1, C2) with interconnected set and reset inputs. Each counter output is used respectively to provide set and reset for a flip-flop (FF). A final monostable provides a triggered pulse in the event of signal error. The time constants of the pulse generators and the counter lengths determine the regenerative pulse triggering.

Title: Direct conversion of light into electrical energy - using electret as light collector for photoelectric layer
Inventor: PRUSS GUENTER
IPC: H01L31/04
Filed: 1978-12-02
Abstract: The electret is made of acrylic glass or similar dielectric and is loaded with light absorbent pigment. The electret surface opposite to the one exposed to incident light is covered with a layer of photoelectric material. The electret is formed by polarising the loaded dielectric with a high voltage field whilst it is heated and allowed to cool. Each pigment molecule then forms a powerfully polarised dipole. This allows light energy falling on the electret surface to be absorbed without reflection. The incoming light passing through the electric field of the electret impinges upon the photoelectric layer and is converted directly into electrical energy. A much greater amount of the incident light is converted by this arrangement into electrical energy.

Title: Protector synchronisation in telecine unit - has shutter produced synchronisation signal compared to TV synchroniser to correct for 18 and 24 FPS compatibility
Inventor: RUMLAND RAINER ING GRAD
IPC: H04N3/38
Filed: 1979-04-11
Abstract: The film projection section is for a telecine unit which can replay both 18 and 24 frame per second films without causing flicker of strobing on the TV picture. The method uses clock pulses synchronisation between the TV field frequency and projector shutter, to avoid using expensive polygonal shutter units, and also avoids sound track speed alterations of 7 and 4% for 18 and 24 f.p.s. replay respectively. The equipment uses a claw drive film transport and fade-out diaphragm. The diaphragm produces a pulse signal from which a correction signal (KBS) is derived to control the TV picture. The method is suitable for single, double, triple or four bladed shutters and by comparing the shutter/apeture frequency with the picture frequency of the TV a sawtooth correction signal is produced to synchronise TV scan with picture exposure for exposure durations which compensate for the different f.p.s. rates between projector and TV.

Title: Ion exchanger regeneration solns. neutralisation - in common tank for acid and alkaline waste and pass-through neutraliser
Inventor: THELEN PETER
IPC: B01J49/08
Filed: 1979-04-14
Abstract: Acid which is passed through the cation exchanger column of a water deminateralisation plant for regeneration is passed in the same tank as the alkaline soln., passed for regeneration through the anion exchanger column. Acid is always held at a sufficient level to ensure a slightly acid mixt. in tank. Pump circulates the mixt. around the tank and through a final pass-through neutralisation tank, contg. a basic material such as MgO. This is a simple and inexpensive plant for the regeneration of both ion exchangers. It eliminates the long neutralisation times and requires only low-cost materials (MgO).
