Title: Circuit arrangement for recoding a binary digital information flow into an nB/(n+1) B line code
Inventor: HANKE GERHARD DIPL ING
IPC: H04L25/49
Filed: 1982-09-28
Abstract: Known serial methods solve this by subdividing the information flow into words with the same number of bits, word-by-word checking for equal weighting of the 0-bits with respect to the 1-bits, possible inverting of at least one word for restoring missing equilibrium and marking the inverted word by an additional bit per word which is inserted in each case. To achieve a higher recoding speed, the circuit arrangement provides a weighting circuit B at which the words with the same number of bits, formed by subdividing the information flow  phi  1 into n part-flows < phi 1/n>, are present in parallel and in which the number of 1-bits per word are determined in parallel processing and are forwarded as binary number Xi to a first comparison circuit (V1) which determines whether Xi is greater than or less than <n+1/2>. Furthermore, a second comparison circuit (V2), a logic consisting of two AND gates (U1, U2) and one OR gate (O1) for generating an inverting instruction, an adding circuit (A) and a parallel/serial converter (PSW) are provided which recombines the n-fold divided information flow after buffer storage in a second memory (SP2) and - as determined by the inverting instruction (INV) supplied by the logic via a third memory (SP3) ...

Patent DE-3239381-A1 (DE)
Title: Socket pipe seal
IPC: F16L21/025
Filed: 1982-10-23
Abstract: In order to seal socket pipe connections, which consist in particular of mineral materials, an elastic roller cage is used which can be prefitted on the socket of the already laid pipe by means of a centring socket. This centring socket is attached to the socket in an adequately centred position by means of a retaining part or by means of a plurality of retaining tongues which reach a piece in the socket, the radial wall thickness of the retaining part or of the retaining tongues being kept as thin as possible and/or being laid in a recess provided in the socket inner wall such that the insertion force required by the roller cage when the retaining part or retaining tongues are rolling over is either not increased at all or is increased only insignificantly, and hence does not exceed the value which is permitted in accordance with the standards or which is practicable. As a consequence of the position of the centre of gravity of the prefitted roller cage inside the limits of the smallest permissible socket gap, this socket pipe seal is also suitable for roller cage deformations of more than 50% and hence also for sealing DN 100-200 stonewear socket pipes.

Patent DE-3331189-A1 (DE)
Title: Desulphurisation of crude gas
Inventor: STIEF WOLFGANG
IPC: C10K1/20
Filed: 1983-08-30
Abstract: Regeneration air is added to a foul gas which arises in a sewage treatment plant and is desulphurised by means of a purifying mass. The addition is made as a function of the particular rate of foul gas arising, so that an addition of oxygen in excess of the instantaneous oxygen requirement for regeneration is avoided. Exact metering is achieved in a simple manner by continuously measuring the rate of foul gas arising and directly converting the measured value into a control signal which controls a metering valve for the regeneration air fed at a constant upstream pressure.

Title: Bio-coldframe
Inventor: BUETTNER LUTZ
IPC: A01G9/20
Filed: 1984-01-19
Abstract: The walls of the bio-coldframe are formed in the subsoil by kerbstones. On the south side, there is located on this in cement a 50 cm high window, framed in a two-part steel frame, which is double-walled plexiglass on the outside and wired glass (diffuse light incidence) on the inside. The remaining sides are formed by wooden planks provided with a bio-paint coating. The interior is designed with unrottable coconut fibre mats (instead of heat packing or ground heating device), over which a double-galvanised narrow-meshed wire netting is laid, which is nailed to the wooden walls with staples and, on the south side, is bent over the coconut fibre mats 5 cm above the kerbstone upper edge. 2.5 cm below the coldframe upper edge, roof battens are nailed in each case on the longitudinal sides on the squared timbers situated in the corners and in the wall centre, as support for the (removable) transverse battens which end flush with the frame upper edge. The coldframe covering consists of pink slotted film. For ventilation, this can on both longitudinal sides be folded around the roof battens resting thereon for wind protection, after these have been pushed approximately 10 cm towards the frame centre. For freedom from maintenance for a number of days, transverse battens are placed between frame upper edge and slotted film, as a result of which lateral air circulation is ensured.

Title: Device for recovering an armoured vehicle with armoured protection
Inventor: KUESTERS HEINZ PETER DIPL ING
IPC: F41H7/02
Filed: 1984-03-03
Abstract: A device for rapidly recovering an armoured vehicle with armoured protection is proposed, in which a triangular towing-away fork is coupled about horizontally aligned bearings to a swivellable clearing shovel of a retrieving tank. The fork is adjusted by means of the shovel into a transport position, coupling position and pulling position. At the end, it comprises a coupling element, which is connected to a hook of the vehicle to be towed away and is secured via a remote-controllable locking element. The towing-away fork is supported on the shovel via guide devices and is swivellably coupled in the bearings. In each case, a spring element is arranged between the tensioning levers of the device, which element keeps the fork elastic with respect to the shovel. The tensioning levers are of two-armed construction and are arranged in a scissor-like fashion on a common axis of the bearing. Between the free holding arms facing away from the shovel, the spring element which is constructed as a compression spring is provided, the said spring element keeping the tensioning levers in an expanded position.

Patent DE-3423154-A1 (DE)
Title: Process and apparatus for the continuous washing out of web-shaped textile material
IPC: D06B3/12
Filed: 1984-06-22
Abstract: It is known to use full-width washing machines and dwell units for the washing out of printed and already dye-fixed web-shaped textile material which at least partially contains cotton fibres. In front of the fastness wash in the hot state, a cold-washing zone in which the dye pastes first swell is to be arranged. In the process according to the invention, this cold wash is followed by a special dwell zone, in which the squeezed-off textile material dwells through a relatively long period of time in a folded position in this state of low residual moisture. The dye constituent not fixed in the cotton fibre has sufficient time here to diffuse out of the interior of the fibre onto the surface. Only in this way can degrees of fastness satisfactory over the long term be achieved after the subsequent hot wash has been completed.
