Title: DPCM predictive quantisation of picture signals - alters quantisation of differences to be transmitted in preset sequence
Inventor: LIPPMANN REINER DIPL ING
IPC: H04N7/34
Filed: 1977-07-28
Abstract: The system for the predictive quantisation of picture signals by the DPCM method, permits a reduction of the bit rate and total volume of data to be fed to a transmission or storage medium so as to make optimum use of the capacity of the transmission or storage medium. The quantisation of the differences to be transmitted is changed in a pre-set sequence; this may be done within a line, from line to line, or from frame to frame. A three point prediction may be used in which as many as possible adjacent picture elements which are coded with the higher bit number are used for the prediction. In this case the number of elements quantised with the higher step number is equal to the number quantised with the lower step number.

Title: Flat cable exposed to sun - has spaces between conductors covered with opaque film to prevent degradation by UV light
Inventor: SCHAUER FRIEDRICH ING GRAD
IPC: H01B7/08
Filed: 1977-10-06
Abstract: The flat cable, for connecting printed circuits, consists of parallel conductors bonded with adhesive to an insulating foil.

Title: Drying bulk granules, esp. blast furnace slag sand - via plant which includes sieves for draining water from sand
Inventor: MUELLER-SPAETH ERICH
IPC: B03B9/04
Filed: 1977-11-03
Abstract: Molten slag leaving a blast furnace is granulated by spraying with water; and the mixt of sand and water is fed via a gutter into a tank contg a rotating wheel. In the periphery of the wheel is a circular row of sieve troughs, which lift the sand so the water drains through the sieves; and the sand is tipped from the troughs into a hopper feeding a conveyor belt. The water in the tank is fed into a settling basin for clarification, so the water can then be recycled to the spraying nozzles used to granulate the slag. The rotating wheel is pref. located between two filtration gutters from which water can be drained into the tank and/or the settling basin; and each gutter is located below a conveyor belt fitted with scrapers which carry the sand to the hopper. Provides an inexpensive method for draining water from the granulated slag sand.

Title: Low dosage dental X=ray diagnostic appts. - monitors and records signal from TV camera sensing image on fluorescent layer due to transmitted rays (NL 5.12.78)
Inventor: ANDO SHOICHI PROF
IPC: H05G1/38
Filed: 1977-11-21
Abstract: The dental X-ray tube/television camera chain employs only 1/100 of the X-ray dose used in conventional apparatus. After passing through the object being examined, the X-rays impinge on a fluorescent layer (5) at the input of an optical system (6-8).

Title: Automatic focussing device for cameras - has brightness distribution measured photoelectrically from diaphragms equidistantly placed in front of and behind film plane
Inventor: KOENIG GOTTFRIED DR ING
IPC: G02B7/34
Filed: 1978-01-27
Abstract: In the automatic focussing device there are two measuring beam paths derived from the photograph-taking beam path. Each beam encounters an image-field diaphragm. One diaphragm lies in front of an image plane equivalent to the film plane and the other lies at the same distance behind this image plane. Each measuring plane contains a photoreceiver whose output signals are supplied to a measured-value processing circuit. Here, the absolute values of the signal voltages of both measuring beam paths are compared and used to control, in phase, a lens motor and/or an indicator.

Title: Hot and cold water mixer scald prevention fitting - involves choke assembly reducing flow to trickle just below critical temp.
Inventor: HOLZER WALTER
IPC: E03C1/044
Filed: 1978-02-01
Abstract: The shower washbasin and bidet fitting automatically monitors water temperature, and acts as a critical limit to prevent danger of scalding. In the circuit the mixer assembly is followed by a choke element such as wax expansion unit (4) with valve seating (8) and valve heat (13) to reduce normal water flow to a small fraction before scalding temperature is reached. It may completely cut-off outflow while a runoff (18) usually closed permits a reduced volume of water to emerge. Critical temperature may be adjustable by moving the valve seating.

Title: Measurement system for semiconductor mfr. - measures ratio of local resistivity and film thickness of thin semiconductor layers via five contacts
Inventor: HESSE EGBERT PROF DR ING
IPC: G01R31/26
Filed: 1978-04-15
Abstract: The measurement system uses four contact needles located on a circle of arbitrary radius whose presence against the semiconductor results in Schottky contact junctions. Before measurement is made, a fifth resistive contact is attached to the edge of the semiconductor, e.g. by alloying. Whilst measurements are being made, a current is supplied via this fifth contact to overcome the otherwise unavoidable reverse biasing effect of two consecutive Schottky junctions in the same measuring circuit. After measurement, the fifth contact is etched away and the semiconductor's mfg. process continued.

Title: Appts. for cutting labels from strip - uses reflected light from printed marks on labels to initiate cutting operation
Inventor: ROGGENSTEIN HANS PETER
IPC: B65C9/18
Filed: 1978-06-03
Abstract: The cutter for the labels in strip form incorporates a control system activated by reflected light from a light-box. The light is reflected from marks on the label, which are printed on the strip. A contact which is in the connection between the light box and the control closes just before the reflection point, which starts the cutter is reached. This ensures that no other reflecting points on the label can operate the cutter. The contact is operated by a time relay or by a pulse counter.

Title: Fork contact spring for plug connector prodn. - starts with unwinding wire contact from reel, forming zigzag configuration, followed by connection to wire terminal portion
Inventor: BUECHS HUBERT DIPL ING
IPC: H01R43/16
Filed: 1978-09-27
Abstract: The fork-shaped contact spring consists of a contact portion and a connector part and it is intended to be inserted in a recess of an insulator. The contact portion (10) consists of a wire (2) which is supplied from a coil (1). It is straightened and looped in two meandering parts (5, 6). The connector part (11) is formed by a wire (8) unwound from a second coil (7) and secured to the first loop (5). Then it is cut to a desired length. Subsequently the contact portion is severed at the second loop (6), which yields a U-shaped contact spring with a bevelled or rounded surface near the insertion opening. The U shanks converge in the direction of the contact spring opening. The straightening of the wire for the loops is preferably carried out by rolls (4) which simultaneously provide its deformation into a rectangular cross section. Finally the wire may be plaited with a rare metal foil.

Title: Centrally controlled telephone exchange - changes circuit detecting engaged signal for retransmission of dialling pulses
Inventor: DIETZE KLAUS DIPL ING
IPC: H04Q3/42
Filed: 1978-10-04
Abstract: The telephone exchange has a circuit for d.c. signalling of readiness to receive dialling pulses by a connecting circuit recognising the engagement of a line by a subscriber. After evaluation of an engagement signal received by the connecting circuit, the central control unit changes the d.c. circuit detecting this signal and running between the connection point and the connecting circuit. A selector responding to this change enables the retransmission of the dialling pulses for further processing. A recognition circuit (E) ascertains when an engaged signal arrives on the connecting pair (ASL). It extends this signal to the central unit (ZSE) via a lead (B). The return leg (W) enables the unit (ZSE) to extend a demand to the coupling unit (A).
