Patent DE-2932876-A1 (DE)
Title: AVC to adjust car radio volume - using microphone to control amplifier gain according to external noise level
Inventor: RODEWALD HEINRICH
IPC: H03G3/32
Filed: 1979-08-14
Abstract: The volume control has a microphone picking up external noise caused by the movement of the vehicle. The microphone output signal is converted into a gain control signal for the radio amplifier. The gain control signal may also be made dependent on the speed of the vehicle by including the output from a tachometer or engine speed detector. The control can also be used with tape cassettes and citizen's band radio. A potentiometer allows the user to set the baseline volume to the value he prefers.

Patent DE-2938193-A1 (DE)
Inventor: JANKE BERNHARD
IPC: E06B7/23
Filed: 1979-09-21
Abstract: Doors and windows may be sealed in a particularly efficient manner by arranging on their periphery a flexible sealing tube which is adapted to be expanded by means of a pump which serves to pressurize a liquid with which the tube is filled. The invention is directed to a novel pump which is adapted, independently of the existing temperature, to adjust the desired liquid pressure in the sealing tube. The pump of the invention, while being of compact design, is also adapted for use with windows or doors covering very large openings. This is made possible by the use of an independent supply reservoir for the pressurized liquid, the reservoir being connected to said pump and being also connected to said sealing tube by means of a first valve which is adapted to be operated by a closing device. Between the pump and the sealing tube there is provided a second valve which is adapted to be opened towards the sealing tube.

Title: Decorative layer press bonding - using antistick cloth on diaphragm covering upper press plates
IPC: B30B15/06
Filed: 1980-03-05
Abstract: Decorative layers, specially veneer, is press bonded to a workpiece by laying the workpiece with the veneer on a lower heated press plate which can be raised by power cylinders against an upper heated press plate. The upper plate has a sealing frame and is covered by an elastic diaphragm. The diaphragm is covered on the side towards the veneer by an anti-stick cloth (woven PTFE threads) and on the side towards the plate by anti-stick powder (PTFE). This makes it possible to apply neat decorative layers on profiled workpieces, even those with re-entrant sections of the surface.

Title: Optical fibre cable with intermediate separation layer - compensates contraction differences between outer sheath and inner buffer layer during mfr.
Inventor: ZEIDLER GUENTER DR PHIL
IPC: G02B6/44
Filed: 1980-03-21

Title: Demodulation circuit for unknown channel property wave - has adaptive phase corrector in digital hilbert filter pair
Inventor: GOECKLER HEINZ DIPL ING
IPC: H04L27/01
Filed: 1980-03-27
Abstract: Already in Patent Appl. P3006801 a synchronous demodulation receiver has been described in which analogue signals derived from a band pass channel are regenerated and transformed into analytical signals by means of a Hilbert filter pair. In present this filter pair is made also adaptive, that is, self-adjusting to the parameters of the received signal. This is obtained by a phase subtractor member producing the error vectors and quadrant error derived from the vectorial output signals (zp, zq) derived from the Hilbert filter pair summing circuits. The identified error vectors are utilised for modifying the coefficient input signal (h/p-n, h/q-n) to the multipliers whose other inputs derive from the amplitude-sampled wave form segments in the delay stages (T/1). The continually varying multiplication coefficient derives its sign from an algorithm connecting the sampling clock interval (T), the index (i) of the clock pulse sequence, the adaptor factor for the sample step width, the input signal sequence (u) the difference vector (z-q) the vectors at the input and output of the so called decision circuit (Es), and the carrier frequency (f).

Title: Cell culture and gas interaction test container - with gas inlet and motorised circulating impeller
Inventor: HERBOLD BERND AXEL
IPC: C12M1/34
Filed: 1980-09-20
Abstract: An appliance for use in research into the interaction between gases or volatile matter in the gaseous phase with cell culture systems is a round gastight container with a gas connection. A rotor is driven through a gastight spindle from an outside motor. The bottom has recesses for fitting projections of another container, if several are to be assembled to a stack. A round plastic or metal container is closed by a transparent lid, held by three clamping clips. The Petri dishes with the cultures rest on the bottom, surrounding a tray with an evaporable fluid. A tab helps to lever off the lid. Gas is introduced through a pipe with a cock. A motor drives a small propeller. When several containers are assembled to a stack, using recesses at the bottom and projections on the top (not shown), the contacts ensure that all motors operate in parallel. This saves much space, compared with the conventional exciccators. Many containers with different gas concentrations can be stacked in the same incubator.

Title: Audio and video recording on magnetic tape - alternating angled audio and video tracks along tape and setting associated pick=ups at 90 degrees to each other
Inventor: MATSUZAWA YONEO
IPC: G11B20/00
Filed: 1980-10-02
Abstract: A video magnetic tape recording system uses both angled video and audio tracks to avoid the problem of damage associated with tape utilising audio tracks along the tape edge. The angled audio tracks alternate with video tracks along the tape. The tape passes around a drum for recording and replay with audio pick-ups located diametrically opposite each other. The video pick-ups are also located diametrically opposite each other and are set at 90 degrees to the audio pick-ups. A pulse code modulated process is used for the audio signal recording to minimise the noise level.
