Patent DE-3544578-A1 (DE)
Title: Electrically operated apparatus having a housing opening
Inventor: SCHULZE REINHARD DIPL ING
IPC: H01H13/18
Filed: 1985-12-17
Abstract: Doors 4 whose closed position is intended to be monitored have (especially when the monitoring switch 14 is accommodated such that it cannot be touched) a switching finger 11 which, during closing, enters into a channel 12 adjacent to the housing opening and holds the contact plunger 13 of the monitoring switch 14 down. Such doors must be adjusted precisely with respect to the position of the switching finger 11 relative to the channel 12 in order that the switching finger 11 does not become seated on the edge of the channel opening, and break off, when the door 4 is closed. In order to prevent this, the channel 12 has a prismatic catchment opening 15 and the switching finger 11 can be pivoted out laterally against the force of a spring 20 and is supported such that it can be pushed back into the depth of the door 4. <IMAGE>

Title: Heating filament support, hot plate provided therewith, and a method for its production
Inventor: ROMMELSBACHER HERMANN DIPL ING
IPC: H05B3/74
Filed: 1986-01-29
Abstract: A heating filament support (1) for a hot plate consists of a supporting plate which is made of ceramic-fibre material and has, on one side, a heating spiral (9) which is inserted into a groove (10). The depth of the groove (10) is somewhat larger than half the diameter of the turns of the undeformed heating spiral (9), and the width of the groove is somewhat less than the complete diameter of the turns of the undeformed heating spiral (9). The heating spiral (9) is fastened in the groove (10) by means of a silica sol coating. Since the heating spiral (9) is held in a force-fitting manner in the groove (10) as a result of the selected groove dimensions, even before the application of the coating, the coating can be applied by immersing the heating filament support, with the spiral side facing downwards, into an aqueous silica sol suspension, which preferably contains talcum. <IMAGE>
Patent DE-3603849-A1 (DE)
IPC: H02G3/04
Filed: 1986-02-07
Abstract: A fitting (1) for a cable duct tube is provided, for use in the telecommunications field in the form of a protective tube flat bed (9) which can be deformed into a tube bundle (10). Simple storage and handling of the fitting (1) are provided by assembling the protective tubes (2,3,4,5) into a flat bed, and as a result of their capability to be wound. Improved stiffness and shape retaining capability of the tube bundle (10) formed by deformation of the protective tube flat bed (9), together with an improved capability to fill the cross-section of the available cable channel duct, is achieved by means of a basic triangular cross-section shape of the tube walls (11,12,13) together with an outer wall (13) which has a curved shape.   <IMAGE>
Patent DE-3605315-A1 (DE)
Title: Force measuring cell with capacitive displacement measurement
Inventor: KUBLI RUDOLF DR SC TECHN
IPC: G01L1/26
Filed: 1986-02-19
Abstract: The force measuring cell has at least two mechanically coupled force sensors (1, 2) with a common load carrier (3). Each force sensor consists of a measuring device (4 to 7) which is resiliently compliant under load and a capacitive displacement sensor (11 to 14) which detects the load-dependent resilient yielding of the measuring device. The sum of the capacitances of the two force sensors serves as the measure for the force (F) to be measured. Because of this arrangement with a plurality of force sensors, the force measuring cell is relatively insensitive to torques acting on the load carrier. The use of capacitive displacement sensors is particularly favourable, because it is possible in this way to produce all the parts of the measuring devices of at least two force sensors, including parts of the displacement sensor, jointly as a unit from one piece. Units of this type produced using etching technology are in this case not substantially more expensive than individual force sensors of the same design. <IMAGE>
Patent DE-3606935-A1 (DE)
Title: Pressure-volume exchanger with synchronous volume and output exchange
Inventor: TUTTASS EDMOND ING GRAD
IPC: E21F3/00
Filed: 1986-03-04
Abstract: A pressure-volume exchanger with synchronous volume and output exchange serves in particular in air-conditioning systems in underground mining and tunnelling to take the warm water coming from underground directly to the surface and conversely to take the cold water from the surface directly underground. The pressure-volume exchanger forms the intersection here. It has three chambers which are designed as hydraulic cylinders and whose separating pistons, at the same time actuating the regulating members, are connected to one another via tie rods. This automatically makes the filling and circulation output of both the primary and secondary circuit the same. <IMAGE>

Inventor: BAUMGARTNER ALFONS ING GRAD
IPC: G01D5/244
Filed: 1986-04-15
Abstract: In such a measurement transducer, the code tracks (CS1-CS5) of a rotatable code disc (C) are scanned by an opto-electrical scanning unit (A). The binary values (Bn1-Bn5) of the individual digital measurements (Mn), supplied by the scanning unit (A), are present at the parallel inputs (PE1-PE5) of a parallel/serial shift register (PSS), the serial output (SA) of which is connected via a data line (DL) to an evaluating device (AW). An external clock generator (TGE) applies external clock signal sequences (TF), on the one hand, to the clock input (TE) of the parallel/serial shift register (PSS) and, on the other hand, via a differentiating section (DG) to the reset input (RE1, RE2) of a clock-controlled sequential circuit (TSS1), the switching signal (US1) of which is supplied to the parallel/serial switching input (PSU) for switching the parallel/serial shift register (PSS) from parallel mode to serial mode for the serial transmission of the binary values (Bn1-Bn5) of the individual digital measurements (Mn) to the evaluating device (AW). The clock-controlled sequential circuit (TSS1) contains a serial/serial shift register (SSS) with two bistable flip flops (FF1-FF2) and an internal clock generator (TG1) which supplies an internal clock signal (TS1) to the clock inputs (TE1, TE2) of the two bistable flip flops (FF1, FF2). <IMAGE>

Title: Tap
Inventor: KROME HELMUT
IPC: B67D1/14
Filed: 1986-10-31
Abstract: A tap, especially for drinks, such as beer, or possibly wine or the like, which are permeated with a gas, such as carbon dioxide or nitrogen, which tap has a pipe section which points towards the supply vessel, is connected to a section containing the tap and is provided with a conical aperture which tapers in the direction of the supply vessel and in which a correspondingly shaped cone of a so-called compensator engages, which can be adjusted by means of a handle in the axial direction of the pipe section, is to be designed in such a way that vibration of the compensator is reliably prevented. Precise adjustability of the compensator is also not to be impaired. To achieve this, provision is made according to the invention for the compensator to be fixedly arranged on the section containing the tap and for the tap section to be displaceable with respect to the pipe section adjoining it and facing the supply vessel.
Patent DE-3638076-A1 (DE)
Title: Shifting device for a side-working mow-cutting unit
Inventor: HUEBING HOLGER
IPC: A01D75/18
Filed: 1986-11-07
Abstract: Side-working mow-cutting units 2 of mowing unit 1, which are mounted on tractors or the like must, in order to mow the verges of roads and the like, shift aside from the posts, boundary stones, trees and such-like obstacles 3 present there, without coming into contact with them, interrupting their travel and leaving behind relatively large unmown surface regions, at a low outlay in operating terms. For this purpose, there is arranged flexibly above, in front of and over the length of the mow-cutting unit 2 a tracer bar 4, as a result of the backward displacement of which in relation to the mow-cutting unit 2 when the obstacle 3 is encountered a double-acting hydraulic mover 5 keeping the mow-cutting unit 2 in the working position is loaded with hydraulic oil in such a way that the mow-cutting unit 2 always remains at a relatively short distance from the obstacle 3 and, after the obstacle has been left behind, the mow-cutting unit 2 is pivoted back into the initial position in an accelerated manner. <IMAGE>

Title: Device for desoldering components from boards
Inventor: JASCHKE GEORG
IPC: H05K13/04
Filed: 1986-11-10
Abstract: The invention relates to a device for desoldering components from boards. For cost reasons, cost-effective desoldering aids are used for occasional desoldering. More expensive desoldering apparatuses and desoldering stations are used for frequent desolderings. The problem now exists of specifying a device for desoldering components, the efficiency of which device exceeds that of the desoldering aids, but which device on the other hand avoids a major outlay such as that in the case of the desoldering apparatuses and desoldering stations. A desoldering bit (2) is specified for this purpose which at the free end has an attachment (21) with a recessed hole (22), the axis of the hole running approximately at right angles to the axis of the desoldering bit and, in the desoldering state, the hole being directed on the one hand to the bit (31) of a vacuum desoldering apparatus (3) and on the other hand to the solder point (41) of the component (42), on the board (4), to be desoldered. The device can be used advantageously both for mechanics and craftsmen. <IMAGE>
Patent DE-3638686-A1 (DE)
Title: Method for controlling points drives in railway shunting systems
Inventor: LEBEK HANSJOERG
IPC: B61L5/06
Filed: 1986-11-13
Abstract: In order to shorten the time between the outputting of an instruction for resetting a set of points until the new final position is reached, the running-direction selectors which switch in each case before the control switches which switch the supply voltage respond are switched over in each case after rotation of a drive in preparation for the next switch-over process. The shortening of setting time which can be achieved in this way makes it possible to shorten in length the track elements which lie in front of the individual points and are to be kept free before change-over commands are triggered. This is in turn one of the preconditions for achieving higher shunting capacities.
Patent DE-3640780-A1 (DE)
Title: Ideal aerofoil section for the wings (vanes) of fluid-dynamic installations
Inventor: BLAUER MIKLOS ZOLTAN
IPC: B63H1/26
Filed: 1986-11-28
Abstract: No "Bernoulli forces" occur on the wing of aircraft or in fluid dynamic installations because the flow around the aerofoil starts from an entry point which is characterised in that the flow movements from the "entry point to outlet point" are equal on both sides of the aerofoil. The flow direction and these points determine an incidence angle, on the basis of which the forces can be calculated by using the normal physical laws. As a result of the drags, the aerofoil profile is intended to be designed with the maximum possible radii, in accordance with which it has sharp leading and trailing edges. This at the same time proves the previously incorrect design of the "streamlined body". <IMAGE>

Patent DE-3643388-A1 (DE)
Title: Electrically activated lock
Inventor: MAUER GUENTER
IPC: E05B59/00
Filed: 1986-12-19
Abstract: The object of the invention is to provide an inexpensive electrically activated lock which can be exchanged for conventional standard locks and which requires such low electrical power that it can be fed by means of a dry battery. This object is achieved in that the lock follower receives a knife-edge lever which, in the state of rest, presses an armature up against the yoke of an electromagnet via a spring-loaded control lever. When the door handle is actuated and the magnet energised, the knife edge of the lever runs past a stop pin; when the magnet is not energised, the control lever pivots round and the knife edge runs up against the stop pin. <IMAGE>

Title: Covering apparatus for swimming pools or the like
Inventor: SCHIRMER ECKHARD
IPC: E04H4/10
Filed: 1987-01-10
Abstract: A covering apparatus for a swimming pool or the like, having a covering sheet (1) which can be wound onto a winding shaft (43), having profile rails (2) which are fastened along opposite pool borders and in which the covering sheet (1) is guided and held, by means of guide elements (13) arranged on opposite side borders, when drawing it off the winding shaft (43) and winding it onto said shaft, and having in each case one pulling element (12) which is assigned to the profile rails (2), acts on the covering sheet (1) and is intended for unwinding the covering sheet (1) from the winding shaft (43). In order to ensure simple guidance of the covering sheet (1) in the profile rails (2) without twisting, each pulling element is a non-expansible pulling band (12) which is fastened at that end of the covering sheet (1) which is directed away from the winding shaft (43), which is guided around a deflection roller at the far end of the profile rail (2) and which can be wound up onto a winding roller (45). The winding rollers (45) for the two pulling bands (12) can rotate synchronously (Figure 1). <IMAGE>

Title: Fuel injection nozzle for internal combustion engines
Inventor: FUESSNER PAUL DIPL ING
IPC: F02M45/08
Filed: 1987-01-15
Abstract: Fuel injection nozzle for pilot and main injection with an inwardly opening valve needle (16), the closing spring (26) of which is supported on a piston (32) guided in a cylinder bore (34) and presses the said piston against a valve seat (38) on the entry of a fuel feed line (18, 35, 36) into the cylinder bore (34). After a pilot injection phase the fuel forces the deflection piston (32) away from the valve seat (38), whereupon fuel flows into the cylinder bore (34) and the rise in the fuel pressure thereby experiences a temporary interruption, producing a marked transition between pilot and main injection phase. According to the invention, the deflection piston (32) forms a lift stop limiting the maximum opening lift of the valve needle (16) and is dimensioned for this purpose so that in its lift stop position the force exerted on it by the fuel in the cylinder bore (34) exceeds the sum of all counteracting forces. As a result, an intermediate disc between the nozzle body (10) and the nozzle holder (14), serving as lift stop for the valve needle (16), can be dispensed with. <IMAGE>

Title: Refrigerating plant
Inventor: BURK ROLAND DIPL ING
IPC: F25B49/02
Filed: 1987-02-24
Abstract: A refrigerating plant (1) has a coolant circuit containing, in sequence, a compressor (2), a condenser (3), a pressure-reducing valve (4), an intermediate-pressure collector (5), a throttle (6) and an evaporator (7). In the circuit, the intermediate-pressure collector (5) is connected to the compressor (2) by a separate connecting pipe (8) for feeding in intermediate-pressure gas. Simple setting of the mass flow of the intermediate-pressure gas and easy adjustment of the refrigerating plant (1) to varying operating conditions are achieved in this plant by having a pressure-reducing valve (9) and a non-return valve (10) located in the connecting pipe (8) that connects the intermediate-pressure collector (5) to the compressor (2). The pressure-reducing valve (9) causes a defined mass flow of the intermediate-pressure gas to be pumped to the compressor (2), even under varying operating conditions. Furthermore, an increase in refrigerating capacity and in the performance figure and a lowering of the temperature of the hot gas are thereby achieved. <IMAGE>

Abstract: The invention concerns a pedal-crank drive, preferably for bicycles, with two pedal cranks offset by 180@ and turning about a common axle, and two telescopic, adjustable-length levers, each hinged on the frame and on the free end of a crank pin of the pedal crank on one side of the bicycle. The levers each bear a pedal on the part of them extending beyond the hinge point on the crank pin, so that when a pedal is pressed down, the distance between the axle of the pedal and the axle of the crank is lengthened, and shortened when a pedal is lifted. In the pedal-crank drive according to the invention, the levers take the form of pantograph linkages, with one or more scissor links connected together by hinges, with the free ends of the two outer scissor links being connected via two toggle rods each with a common hinge pivot. The two pantograph linkages are hinged to the bicycle frame at a hinge pivot of the two outer toggle rods, while the hinge pivots of the two other outer toggle rods each bear a pedal. The crank pins of the pedal cranks are each hinged to the pantograph linkages at a middle hinge pivot of a scissor link. By displacing the middle hinge pivots of a scissor link, different paths for the pedals can be generated. Furthermore, the ... Original abstract incomplete.
