Title: Temperature measuring device with transmission of measured values by optical fibre
Inventor: BUSCH WINFRIED DIPL ING
IPC: G01K5/72
Filed: 1985-12-07
Abstract: Temperature measuring device having a sensor (10) and two optical fibres (1, 2). Aiming at a compact design of such a device, the sensor (10) has a position indicator (7) which can rotate about an axis (A2) and is in the form of a disc (8) having a partially reflecting surface pattern (9). The two optical fibres (1, 2) are aligned with their ends (5) parallel but eccentric with respect to the axis (A2) of rotation and arranged on the same side of the disc (8). As a result, a fraction of the measured light which is proportional to the angular position of the disc (8) is reflected into the second optical fibre (2). The device can be inserted with particular advantage into a cylindrical bore of the iron core of a transformer. <IMAGE>

Title: Holding device, in particular for circuit boards
Inventor: GEBHARDT KLAUS
IPC: G01R1/073
Filed: 1986-01-24
Abstract: A suction plate (11) (Fig. 3) serves for holding board-shaped objects, in particular circuit boards (2). It has a multiplicity of suction openings (14) facing the board to be held. A valve body (19) is provided for each suction opening (14) and can be brought to bear against the inner mouth (20) of the latter and closes it. The suction plate (11) is designed hollow with a suction chamber (12) which is bounded on the one side by a perforated plate (15) and on the rear side by a cover plate (13). The valve bodies (19) are mounted displaceably in the manner of pistons in guide bores (25) which are arranged coaxially with the assigned suction opening (14). A pin (21) connected to the valve bodies (19) engages freely through the suction opening (14) and serves for actuating the valve by means of a sucked-on circuit board (2). The rear-side end face of the valve bodies (19) is designed as a pressure surface (26) connected to the surrounding atmosphere. A restoring force acting in the closing direction on the valve bodies (19) arises as a result of this external pressure application and the internal pressure application in the region of the suction chamber (12). A progressive restoring force arises in the desired manner in the closing direction as a result of flow conditions occurring in the region of the suction openings. As a result of this, only a small repelling force is applied to the circuit board (2) in the open position of the valve and furthermore, by means of this design, small...

Title: Control valve, in particular a parallel slide gate
Inventor: LUETZKE KLAUS DR ING
IPC: F16K47/04
Filed: 1986-05-07
Abstract: The invention relates to a control valve for controlling the rate of flow of a flow medium, having a slide plate and a flow opening which can be closed by the slide plate. The slide plate has a flow window with a cross-sectional area matched to the flow cross-section of the flow opening in such a way that when the flow window intersects with the flow opening the flow area exposed in each case is proportional by a given exponential power to the lift of the slide plate. This achieves a control characteristic on the basis of which an approximately constant response sensitivity is obtained over the entire control range. <IMAGE>
Patent DE-3622725-A1 (DE)
Title: Rotating sleeve or centre
Inventor: BRUCKNER KARL DIPL ING
IPC: B23B23/04
Filed: 1986-07-05
Abstract: In order in the case of a rotating sleeve or a rotating centre for a lathe or grinding machine, to prevent the intrusion of water, in particular liquid coolant for the workpiece to be machined, into the interior (17) of the housing (1), and thereby to protect the bearings (6 and 7) against damage, this interior is sealed off from the rotor (3) at its end on the centre side by means of an annular sealing element (5). This sealing element alone has, however, proved to be insufficient, and for this reason the invention provides to insert ahead of the sealing element (5) at least one annular gap (15, 16) behind which - seen from outside inwards - an annular space (13, 14) is located in each case. This annular space can be drained via a run-off channel (11, 12) which is arranged on its underside and leads to the outside. The run-off channel is preferably formed by the housing (1) and, in particular, by its annular, removable housing part (10). It can in each case, be supplemented or enlarged by a circumferential groove (21, 22). <IMAGE>

Title: Wave-driven power-harnessing plant having a flood-controlled water accumulator set up for operating a buoyancy power-harnessing plant
Inventor: RADEBOLD CLAUS
IPC: F03B13/18
Filed: 1986-07-07
Abstract: Float beams which are mounted movably opposite one another on the equipment of the wave-driven power-harnessing plant are moved by the waves and output the power harnessed during the up and down motion to a common axle. A water accumulator located in the water maintains in the equipment the highest water level determined in each case by the flooding from outside. The water level is reduced in the equipment only when water in the equipment itself - driven by a water pump - flows out to the outside. This takes place when there is temporarily a lower water level on the outside, e.g. due to the waves. The wave-driven power-harnessing plant and flood-controlled water accumulator are suitable, when combined to form a unit, for permitting the economically favourable operation of a buoyancy power-harnessing plant - Patent Application No. P 3441408.8-15 - by making use of the conditions at ebb and flood tides as well as the conditions of the waves, provided that specific wave heights are not fallen below.

Title: Divisible clamping head with an integrated strain-gauge force transducer for the clamping of tension samples
Inventor: HECK SIEGFRIED
IPC: G01N3/04
Filed: 1986-10-24
Abstract: In the tension impact test, it is advantageous if the force sensor is arranged as near as possible to the sample-clamping clamping surface in the clamping head. Since the tension impact test on plastics is useful primarily when there is temperature control, the clamping head is to be divisible, and the sample-clamping parts are to be clamped onto the sample outside the test machine, and the sample, together with the clamping-head parts, is to be capable of being mounted quickly, without a tool, in the temperature-control chamber of the test machine. The connection of the two pressure plates (1) to the carrier (2) by means of the insertable bolt (3) meets both requirements simultaneously, Figure 2. When the sample (7) is loaded with the test force (F), there arise laterally of the bolt (3), in the zones (5) and (6), tensile stresses which are proportional to the test force (F) and on which no friction is superposed as a result of the gap. Strain gauges (8) or (9) fastened in the zones (5) or (6) constitute, with these, the force sensor located near the clamping surfaces (12). The clamping head is divisible by means of the insertable bolt (3), and the pressure plates (1) can be clamped to the sample outside the test machine in a fixture and, by means of the bolt (3), can be mounted on the carrier (2) connected to the test machine (11). <IMAGE>

Title: Phase- and amplitude-controlled loudspeaker with an arbitrary number of paths
Inventor: RIEDER JOACHIM
IPC: H04R3/04
Filed: 1986-11-05
Abstract: Ever since Edison has invented his "phonograph", it has been attempted all over the world to improve the sound reproduction. Even though present-day recording capabilities are almost perfect, the weak point in the reproduction is still the sound transducer as before. This transducer reconverts the electrical signals into sound waves. The sound transducer principle used most often operates by electrodynamic means. The current flow in all electrodynamic machines is quite significantly dependent on the mutual induction voltage. This voltage is used for controlling the sound transducer diaphragm in the loudspeaker principle described, but any other control principle can also be applied. However, the essential problem of loudspeakers, including active concepts, is the interaction of the individual sound transducer systems. And this has hitherto not been solved. The principle described in the text which follows is based on the fact that an interaction between individual sound transducers is only possible if these are combined in their control electronics. The further consequence of these considerations is that this can be achieved most simply with only one amplifier and one passive frequency filter. This is also the most inexpensive solution of the problem even if other solutions are conceivable. The design requires an electronic circuit which has previously not been used in loudspeaker construction but is known from analog computer technology. This circuit also allows a ...

Title: Circuit for ancillary telephone devices powered by the connection line
Inventor: SCHIEMANN WOLFGANG
IPC: H04M19/08
Filed: 1987-04-25
Abstract: The circuit is enabled or disabled by an input switch. When it is enabled, a supply line for an ancillary telephone device is activated and deactivated as a function of the loop condition on the telephone terminal device. In known circuits, the loop condition would be determined via a resistor inserted in the connection line which would either be a relay or would serve to measure the loop current. A capacitor is connected via a charging diode and the input switch to the positive wire of the connection line and also to the transmission diode of a first optocoupler whose reception transistor is connected at one end to the input switch and at the other end to the supply line. A reception transistor of a second optocoupler whose transmission diode is likewise connected to the supply line is connected in parallel with the aforementioned reception transistor. This circuit can be used, for example, in a blocking device of telephone terminals. It is characterised by fast operation, lack of wear and simple connectability.

Title: Brake pressure control device
Inventor: BURGDORF JOCHEN
IPC: B60T8/34
Filed: 1987-08-29
Abstract: The invention relates to a brake pressure control device, especially an antilock control device, traction control device, or starting wheel slip control device for hydraulic brake systems for motor vehicles. The hydraulic brake system comprises a static front axle brake circuit and a dynamic rear axle brake circuit. The dynamic rear axle brake circuit serves for actuation of the working piston (53) of a master cylinder (4), which applies pressure medium to the wheel cylinders of the wheels of the rear axle. A hydraulic brake booster (1) is assigned to the dynamic rear axle brake circuit. A servo piston (39, 46) is provided, which is acted upon by the pressure of the static front axle brake circuit. Should the dynamic rear axle brake circuit fail, the servo piston (39, 46), by virtue of its pressurisation by the static front axle brake circuit, exerts a force on the working piston (53) of the master cylinder (4). The brakes (9, 10) of the rear axle are therefore operated, specifically by the static front axle brake circuit, despite failure of the dynamic rear axle brake circuit. <IMAGE>

Title: Electronic camera for the documentation of fluorescence patterns on electrophoretic gels
Inventor: HEIL WILFRIED
IPC: G01N27/447
Filed: 1988-04-18
Abstract: The normal documentation of electrophoretic gels by means of instant photographs is cumbersome and costly. The focusing of the camera is possible only with difficulty in the case of originals of low light intensity. The image of the original is integrated over the desired exposure time on a CCD-image receiver, cooled to reduce the dark current. An interference filter serves for the selection of the spectral ranges of interest. The integrated image is transmitted into a control device and digitally stored there. The image is printed out on thermal paper via a video printer. A video monitor is used for adjusting the focusing and framing of the image. The camera enables cost-effective documentation of electrophoretic gels in biochemical analysis.

Title: Invertor for an inductive load
Inventor: KRUMMEL PETER ING GRAD
IPC: H03K17/06
Filed: 1988-04-22
Abstract: In invertors formed by means of switch bridge circuits, at least one of the corresponding electronic switches is to be controlled in floating mode because the control circuit, on the one hand, and the electronic switch, on the other hand, have a different reference potential. The floating control of electronic switches can be produced using special control-signal transmission elements. As the control-signal transmission element (SE), it is proposed to make use of a circuit comprising a controllable current source (SQ), a detector circuit (DS) which generates a control signal from the intensity of the current (io) from the current source (SQ), as well as a drive stage which is used for controlling the relevant switching transistor (S1, S11, S21) and is connected to the detector circuit (DS) via a control-signal blocking device (BE). <IMAGE>
