Patent DE-3410513-A1 (DE)
Title: Temperature measuring device
Inventor: BOTH DORIS
IPC: G01K11/28
Filed: 1984-03-22
Abstract: A temperature measuring device is proposed having a completely sealed glass housing tube which contains a liquid within which there float individual displacement bodies which in relation to one another in each case have different displacement volumes and/or total weights and embody within the liquid a measure of an assigned temperature value. The displacement bodies each have a float which is weighted by means of a weighting body. Each weighting body is constructed as a hollow body which accommodates weighting weights in the interior and whose external volume can be adjusted and set without again changing the weight set by the weighting weights. The hollow body consists of a sleeve into which a threaded plug is screwed with an interference fit. The adjustment can thus be accomplished without difficulty and, above all, very quickly and without the risk of rejection and, in the process, very exactly.
Patent DE-3411139-A1 (DE)
Title: Quantitative dosing head
IPC: B01J4/02
Filed: 1984-03-26
Abstract: As a result of progressive automation in applying materials such as adhesives and sealants, fats, pastes and similar materials, elements are increasingly required which are able to adjust a flow of material rapidly and at will. According to the prior art, the flow of a material can only be controlled slowly via the dosing device. The dosing heads used at present have the drawback of tending to clog and of material moving during the switching process, because dosing is achieved by means of the opening travel of a cone element in a seating. The novel quantitative dosing head is both rapidly adjustable and free of movement of material, since the piston rod runs through the entire dosing chamber. By shaping the piston rod in different ways, it is possible both to regulate a very wide variety of materials and to control various flow rates. <IMAGE>
Patent DE-3424495-A1 (DE)
Title: Switching device for a drive motor
IPC: H02P3/24
Filed: 1984-07-04
Abstract: The invention relates to a switching device for a drive motor, for example a single-phase induction motor, having an operating capacitor which is utilised, for example, for driving a circular saw and which has a switching contactor which, after connection, is latched via a latching circuit, and has a DC braking circuit which becomes effective via a phase-controlled thyristor for a predetermined time interval after disconnection, the switching contactor alternately connecting the motor to the mains and the windings of the same to the braking circuit. In order to achieve reliable removal of power from the braking circuit once the braking interval has elapsed even in the event of defective components of the control loop or in the event of a defective thyristor, and hence in order to protect the windings of the motor both against overloads and to protect said windings against renewed starting, a contact of a relay which can be energised via the switching contactor is provided in the DC braking circuit, which contact drops out with a delay once the predetermined time interval for driving the thyristor has been completed, so that the braking interval itself is not adversely affected. The delay can be achieved easily in this case by connecting the winding of the relay in series with that of the switching contactor and a diode and by the relay winding being connected in parallel with a charging capacitor which can also be used as the power supply for the drive.

Title: Circuit arrangement for adaptive threshold value formation for a binary image acquisition
Inventor: HEWKIN PETER FREDERICK DR
IPC: H04N5/243
Filed: 1985-07-11
Abstract: The digitised video signals from a video camera are processed in two separate channels. The first channel, for bright video signals, consists of a first multiplexer (3) and the first comparator (5). The maximum values (the brightest parts of the picture) stored in the first multiplexer (3) are compared here with the signals just arriving from the A/D converter (2). The new maximum value is stored again as new in the first multiplexer (3), and released via the following driver (8), so that an evaluation circuit (10) connected in series can be controlled. The channel for dark video signals consists of the second multiplexer (4) and the second comparator (6), and works in the same way as the other channel. The driver (9) which is connected in series releases the minimum values (the darkest parts of the picture) to the evaluation circuit (10). A control logic (7) is connected in series to the comparators (5 and 6), to store the respective maximum and minimum values in the appropriate multiplexers (3 or 4), and to ensure that the multiplexers (3 and 4) are set to an initial value after every picture change pulse (VDR). <IMAGE>

Patent DE-3528781-A1 (DE)
Title: Proportional choke valve
Inventor: WOELFGES HANS
IPC: F16K39/04
Filed: 1985-08-10
Abstract: A proportional choke valve changes the choke cross-section as a function of a control signal and thus determines the rate of flow. The invention relates to a choke valve in which the position of the valve member remains constant irrespective of pressure fluctuations upstream and downstream of the choke cross-section. To this end, the pressure acts on opposing valve-member surfaces of the same size. An annular surface of the same size opposite the control surface is acted upon by the pressure in a tank line leading from the pressure-relief valve for setting the control pressure, so that pressure fluctuations in this tank line cause corresponding changes in the control pressure and the position of the valve member remains constant.
Patent DE-3531000-A1 (DE)
Title: Device for reducing the throttle losses in piston engines under partial load by phase control of the valves
Inventor: GOHLE HERBERT DIPL ING
IPC: F01L1/12
Filed: 1985-08-30
Abstract: The necessary variability of the timing points of a valve timing gear, primarily for internal combustion engines, for preventing throttle losses in the induction and working stroke at partial load is realised in the present application in the same way as a conventional cam shaft control, with recovery of the energy expended in valve actuation, in that the opening and closing sequence is performed by 2 different control cams running at an adjustable phase angle to the crankshaft. At the same time the valves are spring-loaded in the closing direction in the conventional way. A mechanical drive is chosen in which a correspondingly supported control lever (for example a rocker 5) is so actuated by the two control cams (1 and 2) that the valve is opened only when both control cams are run out (in position 1). By corresponding selection of the phase position of the four control cams - two per valve - the four timing points can be adjusted as required. <IMAGE>
