Title: Guardshields for police use
Inventor: RUETTINGER ARMIN
IPC: F41H9/10
Filed: 1982-03-31
Abstract: A guardshield (10) has on its inside two arm straps (14) and a handle (16), between which extends a flat box screwed to the inside of the shield and closed by means of an upholstered arm rest (60). The upholstered arm rest has two side beads and a middle arm recess. Retained in the two side beads are two gas bottles (18), of which the heads (20), when pressed inwards, discharge gas through an outlet tube (36) and passage orifices in the box bottom and in the shield (10). The gas bottle (18) is activated by means of a grip ring (30) which is added to the handle (16), a lever (24) being pivoted and, via a linkage, pressing a thrust plate (50) against the head (20) and consequently moving the latter into the gas bottle. The outlet tube (36) of the gas-bottle head terminates directly adjacent to the inner face of the shield and is oriented at right angles to this. The box bottom and the shield have mutually coincidental passage orifices (22), in the region of which the axis of the tube (36) comes to rest in the spraying position. <IMAGE>

Title: Induction casting machine and casting process
Inventor: BLECHNER CHARLES
IPC: H05B6/24
Filed: 1982-05-14
Abstract: A casting system includes a sheathing to cover a dish-shaped inlet opening to an investment cavity, in investment casting or lost wax casting. A feed system to feed an inert gas into the sheathing is provided to expel the original atmosphere through an outlet opening. The gas supply system also creates a high pressure environment in the sheathing, to push molten metal, taken up in the inlet opening, via casting channels into the mould cavity. An induction heater is provided to melt a solid metal bar, and is controlled by a timer and a pyrometer such that it operates before the injection, and also during and selectively also after the injection of compressed inert gas. The casting system is particularly suitable for low weight metals which can be cast only with difficulty in a centrifuge; it can also be modified for use with glass blocks and metals which do not heat well by induction.

Title: Method and device for machining plier joints
Inventor: BUEHNER HORST
IPC: B23P13/02
Filed: 1982-07-26
Abstract: The object of the invention is to develop a working method and a production device for machining the mating surfaces of plier joints, with which the problem of the forging tolerances, due to production factors, in the unmachined parts of the pliers available as forging blanks is solved in the series production of pliers. The essence of the invention consists in accommodating the unmachined part of the pliers in a positionally orientated manner on the outer joint mating-surface section, to centre it on the running drilling tool for making the rivet hole and then to clamp it and, during the mounting (carried out once) of the unmachined part of the pliers, to finish-machine all joint mating surfaces by machining units movable in opposite directions. The invention is used in the tool industry, in particular in the production of pliers. <IMAGE>
Patent DE-3228634-A1 (DE)
Title: High-resolution digital/analog converter
Inventor: GOETZE GERD-WOLFGANG DIPL ING
IPC: H03M1/00
Filed: 1982-07-31
Abstract: A digital/analog converter is proposed which has a comparatively high resolution. In the digital/analog converter, the bits of the input signal are divided into two groups (A, B). The first bit group passes through a pulse width modulator and the second group passes through an amplitude modulator in the form of a digital/analog converter (28). The outputs of pulse width modulator and digital/analog converter lead to an addition circuit (36), the output signal of which forms the output signal of the digital/analog converter. The last-mentioned circuit can be followed by an amplifier and a demodulator circuit (38), the demodulator of which filters out the useful analog signal. Other bits of the input signal of the digital/analog converter can be used for multiplying the output signal. It is particularly advantageous to use one further bit for identifying the polarity of the analog output signal. <IMAGE>

Patent DE-3231383-A1 (DE)
Title: Optoelectronic dynamometer
Inventor: BARTKOWIAK KLAUS DIPL ING
IPC: G01L1/24
Filed: 1982-08-24
Abstract: The "optoelectronic dynamometer" chiefly serves the electrical detection of very small forces with the aid of approach flow or acceleration. In this case, it is possible to obtain a plurality of components of the measured quantity simultaneously, so that modulus and direction are detected. The basic principle is based on the elastic bending of an optical fibre clamped at one end. x and y components of the force acting perpendicular to the fibre, and thus also the corresponding bending, can be converted into signals optoelectrically using a projection principle without the aid of optical auxiliary means such as lenses. In this case, light guided to the free fibre end and emerging there is projected onto an arrangement of photosensors, as a result of which the latter receive light intensities dependent on the deflection. Possible measured quantities are flow velocity, sound, acceleration (gravity, oscillations), weight and forces or displacements otherwise impressed. Small and cost- effective embodiments are possible, which can supply signals proportional to the measured quantities. Effects of ageing and temperature and other interference effects can be effectively compensated. The drawing shows a typical exemplary embodiment:     1 light source   2 optical fibre clamped at one end   3 optical fibre   4 (a, b, c, d) photosensors, x, y deflection.   <IMAGE>

Title: Electronic controller having safety devices
Inventor: VOSS THOMAS DIPL ING
IPC: F16P3/00
Filed: 1983-02-04
Abstract: An electronic controller having safety devices for a device having mechanical movement sequences with two safety channels of different construction, of which the first safety channel is designed using hard-wired circuit logic and the second safety channel is designed using microcomputer technology, has a common safety stage for both safety channels, which safety stage sets the device to a safe state when different output signals occur on the safety channels. It is intended to improve such a controller for use in cyclically operating devices, with respect to improving the safety and availability of the device. At the same time, it is intended to achieve a construction cost which is as low as possible. To this end, the safety channels carry out identical control functions simultaneously. Furthermore, each safety channel has self-monitoring devices whose signals, together with the comparison result from a comparison of the output signals of the two safety channels, act on a safety stage which sets the device to a safe state when errors occur. <IMAGE>

Title: Method for receiving-end selection of data or speech links routed via an exchange of a telecommunications or telephone system
Inventor: DOSTERSCHILL PETER DR
IPC: H04M3/436
Filed: 1983-08-03
Abstract: A specific receiving-end subscriber station allocates first user-individual reference information to users of any given calling subscriber stations. In order to set up a connection with the receiving-end subscriber station, these users transmit second information corresponding to the first information along with the telephone number of the receiving-end subscriber station to the exchange, while the receiving-end subscriber station transmits selection information corresponding to the first reference information to the exchange. The selection information characterises connections which can or cannot be set up. In the exchange, the second user-individual information is checked to see if is identical to the selection information. Only connections, defined on the basis of the selection information, of identified users of transmitting-end subscriber stations are switched through to the receiving-end subscriber station. The first reference information and the second information may comprise a string of alphanumeric characters, speaker speech samples of the users of transmitting-end subscriber stations or a combination of alphanumeric characters and speaker speech samples.

Patent DE-3337155-A1 (DE)
Title: Motorcycle wheel slip prevention device
Inventor: KAMIYA TADASHI
IPC: B60K28/16
Filed: 1983-10-12
Abstract: The device uses rotation sensors (12,14) associated with respective wheels (11,13) coupled to a control unit which responds to the difference in the rate of rotation of the driving and the driven wheels to provide a control signal indicating the slip rate of the driving wheel (13). The control signal is fed to a drive control, (18) which adjusts the drive force applied to the wheel for eliminating slip.  Pref. a third sensor provides a signal representing the throttle opening and a fourth sensor provides a signal representing the actual value of the carburettor throttle, both these signals also being fed to the control unit which pref. comprises a microprocessor, with the obtained control signal used to correct the carburettor throttle value to eliminate wheel slip.
Patent DE-3339219-A1 (DE)
Title: Heating system
Inventor: NORDHAUSEN JUERGEN DIPL ING
IPC: F24D11/02
Filed: 1983-10-28
Abstract: In a heating system with at least one heat pump connected in a path for a circulating heat carrier, an intermediate section with a non-return valve is provided between the feed and the return of the heat carrier path. The intermediate section divides the heat carrier path into a heat generator circuit and a heat consumer section. The heat generator circuit and the heat consumer section each have at least one circulating pump of their own. When the circulating pump is not delivering in the heat consumer section, the heat pump can continue operating, since the heat carrier can now be circulated in the heat generator circuit, which is closed by the intermediate section, by the circulating pump arranged in it, and thus the required heat withdrawal at the condenser of the heat pump, until an upper temperature limit is reached, is ensured in the heat generator circuit. <IMAGE>

Title: Process for the separation, desorption and detection of dialkyl sulphates contained in air
Inventor: BLOME HELMUT DR
IPC: G01N33/00
Filed: 1984-01-04
Abstract: The invention relates to a process for the separation, desorption and detection of dialkyl sulphates contained in air. The process is to be assigned to the areas of detection and separation of hazardous working materials contained in air. It has not been possible hitherto to adsorb dialkyl sulphates contained in air durably onto a solid collection matrix which is a precondition for a reliable separation system or for a hazardous material detection system using sampling devices based on a solid collection matrix. The invention relates to a process which is able, with the use of a silica gel, found on the basis of extensive trials to be suitable, to adsorb dialkyl sulphates over an extended period. For the sampling system, the invention is supplemented by a suitable process for desorption and a gas-chromatographic separation process using an electrolytic conductivity (Hall) detector for the detection of dialkyl sulphates. Applications for the invention are envisaged on the one hand in the filtering separation devices sector and on the other hand in the sector of testing and detection processes for hazardous materials in air.
