Title: Communications system for speech signals
Inventor: WUERTZ HANS DIPL ING
IPC: H04B1/64
Filed: 1981-03-27
Abstract: To transmit speech via channels with a substantially restricted bandwidth, such as those specified in private land mobile radio, but also in public land mobile radio operating with integrated digital networks, it is proposed to carry out the required frequency band and amplitude compression at the transmitting end by first obtaining a speech signal converted to an RF level via a digital frequency divider (T). The speech signal whose frequency band and amplitude are restricted in this way can then be transmitted in any frequency position to the receiving end in analog or digital form. At the receiving end, the frequency band compression is cancelled at an intermediate frequency level via a digital frequency multiplier (VV) whose multiplication factor n corresponds to the division ratio of the digital frequency divider at the transmitting end. The speech signal is then converted to the AF level so that it can be reproduced. <IMAGE>

Patent DE-3123956-A1 (DE)
Title: Circuit for a light signalling system
Inventor: BECKER JOHAN
IPC: G08B5/36
Filed: 1981-06-16
Abstract: The invention describes a circuit for a light signalling system with the aid of which the nursing personnel is provided with light signals or acoustic signals, especially in hospitals. Known light signalling systems of this type have the disadvantage that, in order to fulfil their various functions, they need three signalling wires and an elaborate and large group switching centre at which the signalling wires for the signals from the individual rooms run together. A light signalling system is also known which manages with two signalling wires but which also needs a large switching centre in a double socket. The invention makes it possible to manage with two signalling wires and to achieve extremely small dimensions for the group switching centre in that the latter, due to the circuit according to the invention, now only has the function of switching logic potentials on the call forwarding line and the call signalling line, depending on the call state which is possible by inexpensive and simple means using, for example, a multiplexer. The call signalling line is used a number of times in this circuit, an emergency call being ensured automatic priority.
Patent DE-3124403-A1 (DE)
Title: Apparatus for framing pictures and decorative articles
Inventor: SCHAILE WERNER
IPC: B44C5/02
Filed: 1981-06-22
Abstract: The patent is primarily a production method representing the production of certain novel products in the craft sector, and especially in the framing of pictures. For the sake of brevity and clarity, the principal product could be called: the novel "rustic frame". This rustic frame is rustic in the fullest sense of the word because it is produced from natural, unprocessed or merely pickled tree branches. The picture is not inserted by means of an undercut or a rabbet but by means of a cast-in frill which also acts as a passe-partout. The casting process makes it possible to preserve the irregularities and curvature and absolute rusticality of the branches, without descending into untidiness or incurring unacceptable production costs. This framing is particularly suitable for natural pictures, hunting themes, hunting lodges and other rooms and premises of generally rustic presentation. The casting process as such can also be used in the same way for other crafts.

Title: Anti-jamming safety device for automatic doors
Inventor: LEDERLE FRANZ
IPC: E05F15/41
Filed: 1981-12-21
Abstract: The invention relates to an anti-jamming safety device for automatic doors which are opened and closed by an electric signal. In order to avoid objects or persons being jammed in, a force measuring device (1) that emits an electric signal is included in the door drive, the force measured by the force measuring device and differing in magnitude as the door moves being linearised by an amplifier (7) whose gain can be varied as a function of the door position, and the value obtained being compared with a desired value. The door drive is switched off or reversed upon overshooting of the tolerance limit. In this arrangement, the force measuring device is preferably a strain gauge, an analog Hall-effect element or a pick-up operated by air pressure. The respective position of the door can be determined by subdividing the path covered by the door into component distances and using a position transmitter (2) to report the door position respectively reached. However, it can also be determined by starting upon commencement of the closing or opening of the door an electronic time measuring device which correspondingly controls the amplifier of the door movement. <IMAGE>
