Patent DE-3044277-A1 (DE)
Title: AC supply and fault supervision for power appts. - using electronic logic circuit for immediate recognition of fault signals
Inventor: GROSS GERHARD
IPC: H02H5/12
Filed: 1980-11-25
Abstract: The circuit is applicable to 3-phase motors and similar power loads. It is primarily intended to monitor the potential of motor frames, but can also be employed to check phase unbalance and other parameters. The circuit checks the potential of the neutral point of an asymmetrical dummy load (1,2,3,24) against that of a comparable symmetrical load (4,5,6). A routing diode (7) applies this potential to an OR-gate (11). If a system asymmetry arises the neutral potential is distorted and the OR-gate (11) operates an electronic latch (12) to put up an alarm (13). The power supply (10) for the electronics is derived from all phases of the mains. Phase sequence supervision (14,15;16,17) employing a multi-vibrator (17) may be added. It can be used in conjunction (18) with the latch output (23) to operate an alarm or tripping relay (19,20). The circuit can respond quickly, and can detect fleeting or intermittent faults.

Title: Optically-triggered, bidirectional thyristor - has two adjacent zone, antiparallel constructions through substrate slice achieving high packing density
Inventor: SILBER DIETER DIPL PHYS DR
IPC: H01L31/111
Filed: 1980-12-06
Abstract: The thyristor is small so that it can be operated by a single light source and is suitable for household equipment etc. It can carry approximately 0.5A. Two weakly doped base zones contain highly doped opposite type emitter zones and highly doped emitter zones of the same semiconductor type. Each emitter zone is physically located opposing its opposite type. These highly doped adjacent zones are electrically connected to one another but the connecting metallisation is separated from the base zone by an insulating layer.

Patent DE-3113360-A1 (DE)
Title: Web-shaped polyethylene-based coating material for the running surface of skis
Inventor: GEISSBUEHLER URS
IPC: A63C5/056
Filed: 1981-04-02
Abstract: The web is built up over its entire length from a centre zone and two outer edge zones based on HDPE. The web has anisotropic properties distributed across its width. For the production of a web of UHMW-PE as base material, a cylindrical composite compression moulding consisting of three layers of pulverulent base material is produced. Either for the two outer layers or the centre layer, the pulverulent base material is used in a mixture with a cross-linking agent, foaming agent or filler. The cylindrical composite compression moulding is then sintered under pressure and a continuous strip is peeled off from the sintered body obtained with the desired thickness of the coating material. Owing to the anisotropic properties distributed symmetrically or asymmetrically across the width of the strip, during use of a ski with such a running surface, the development of a coherent water film covering the entire running surface and thus an impairment of the slip velocity are prevented. The coating material is suitable in particular for the running surface of racing skis.

Title: Magnetically coupled end-fire array
Inventor: BUCK WALTER DR ING
IPC: H01Q19/30
Filed: 1981-05-09
Abstract: In the case of a magnetically coupled end-fire array, which is constructed especially as a YAGI antenna, a two-wire line is provided at at least one end, which two-wire line is short-circuited by means of a clip, is supplied by applying a voltage to a suitable point between the two wires, and is coupled magnetically to at least one dipole (which is arranged at right angles to it and parallel to its plane), a wave guiding structure (which consists of at least one director located in front of the dipole in the transmitting direction) and possibly a reflector. In order to optimize the radio-frequency properties of an end-fire array of this type in a simple and cost-effective manner, means are provided for precise adjustability of the magnetic coupling of the first director and possibly of the reflector to the parallel short-circuit bracket or brackets, which means are preferably implemented by mechanical/structural design of the two-wire line in the region of the end sections. In this way, together with suitably selected rod lengths, the couplings between the first director and possibly the reflector and the short-circuiting brackets on the one hand as well as the dipole on the other hand can be implemented such that the current in these radiating elements corresponds to the respective required value in terms of magnitude and phase. In the case of a design, of these means, which design is particularly expedient from the point of view of simple and cost-effective production, at least one short-circuited end section of the two-wire line is bent through preferably 90 DEG  with respect to its plane and is possibly connected to its remaining part over a line piece which runs parallel to the wires of the two-wire line.

Title: Pneumatic suspension bogie with radially adjustable wheel sets
Inventor: TRIBUKAIT KLAUS DR ING
IPC: B61F5/38
Filed: 1981-05-14
Abstract: The invention relates to a pneumatic suspension bogie with radially adjustable wheel sets. The radial adjustability of the wheel sets serves to reduce the wear of the wheel flange. This is achieved by means of wheel sets (4) which can be rotated in the longitudinal central plane of the bogie about vertical axles, the wheel sets being mounted in U-shaped brackets (11) and the latter being connected in turn to one another in the longitudinal direction by means of connecting element (12). In order to synchronise the rotational movement of the wheel sets (4), the brackets (11) are connected to one another in the external region via levers (14a and 14b), the levers being connected to the bogie frame (1) in a rotatable fashion by means of pivot pins (15a and 15b). In order to control the wheel sets (4) actively, the levers (14a and 14b) are coupled to a hydraulic piston-cylinder unit (16) which is acted on by means of a control unit (18), the control unit (18) being controlled by the play between wheel flange and an inner edge of the rail. In Fig. 2, an exemplary embodiment of the bogie with active control is illustrated.   <IMAGE>

Patent DE-3148023-A1 (DE)
Title: Heating boiler for hot flue gases
Inventor: FISCHER RUDOLF DIPL ING
IPC: F28D21/00
Filed: 1981-12-04
Abstract: The hot flue gas enters laterally through the outer jacket. Two rows of pipes, which are provided in relation to one another in the upper half with double bends or arranged bent at an angle and intersecting, are upright and open in a lower and upper collector, form a space which is open downwards. The pipes, which are welded into the collectors at distances, and flat bars (tubular web) lying between them in the lower half produce the open space. Therein, the flue gas is guided downwards, deflected in the ash chamber, and flows along the two identical outer chambers, delimited by the tubular web wall and the sheet-metal outer jacket, upwards. Above the flue-gas entry point, it passes through the intermediate chambers of the pipes extending at an angle, and flows via the upper collector to the outlet pipe connection. The advantages which can be achieved are optimum combustion of solid fuels in a separate heating insert with lower or upper burn-off and obtaining additional heat in the downstream heating boiler, e.g. for water heating or hot water tanks. This solution is especially advantageous for tiled-stove air-heating systems.
Patent DE-3151387-A1 (DE)
Title: Power transformer
Inventor: BRUEGGEMANN ERICH DR
IPC: F03B17/02
Filed: 1981-12-24
Abstract: The power transformer on a carriage running in an inclined frame on the way downwards divides the force of gravity in that the uplift of a hollow body A in a liquid vessel A strikes an upper fixed frame rail, sometimes at 90 DEG , and is spent. The bottom pressure is increased owing to the increased liquid surface. That proportion of the uplift which is not spent on the upper rail on the other hand counteracts the bottom pressure. The liquid vessel B with the hollow body B is mounted transversely to the liquid vessel A. The hollow body B is forced by the accompanying weights into the liquid to the same degree as in the case of hollow body A. The object of the liquid vessel B is to balance out the forces emanating from liquid vessel A by a resultant, unless it is directed perpendicularly downwards. On the way upwards the rigid connection of the rod is released. The uplift of the hollow body fully counteracts the bottom pressure in the vessel. A balancing weight can thereby be drawn up and energy obtained. <IMAGE>

Patent DE-3205963-A1 (DE)
Title: Cooling device
Inventor: GRUENBERG WOLFGANG
IPC: F25D17/04
Filed: 1982-02-19
Abstract: In a cooling device, a door (1) with a handle (3) mounted pivotably about a pin is provided. Connected rigidly to the handle is a coupling piece (6) which projects into the intermediate space between a door outer wall (2) and a door inner wall. The coupling piece (6) is connected to sealing surfaces (7, 8) which, in the rest position of the handle (3), close openings (9) in the door walls (2, 5) via sealing ring discs (10). If the handle (3) is pivoted by pulling for the purpose of opening the door (1), then the sealing surfaces (7, 8) lift off from the sealing ring discs (10) so that a compensating airflow can flow through the door interior which can moreover be heat-insulated. As a result, pressure compensation in relation to the cooled space is only permitted during opening of the door. <IMAGE>

Title: Arrangement for measuring and monitoring asymmetries in rotating electrical induction machines
Inventor: FROHNE HEINRICH PROF DR
IPC: G01R31/34
Filed: 1982-02-19
Abstract: In this arrangement, taps (6, 7, 8) are provided in the stator winding (4), constructed as coil winding, between the coils and at least at one phase end of one or all phases (1, 2, 3) of the stator winding (4), which taps, conducted via a winding of at least one measuring transformer (12), are connected in such a manner that the voltages induced in the coils, which are caused by asymmetries, produce a value different from zero when added together in the measuring transformer (12) whereas the voltages caused by the basic machine field result in the value zero. The other winding (13) of the measuring transformer is connected to a display device and/or a monitoring device. As a result, the zero voltage system occurring due to the asymmetries in the phases, or the differences of the coil voltages of a phase which are in each case proportional to the asymmetry, can be detected. <IMAGE>

Patent DE-3210238-A1 (DE)
Title: Energy facade in the form of a frontal shell for solid loadbearing and non-loadbearing outer walls
Inventor: MAGER MANFRED
IPC: F24S23/30
Filed: 1982-03-20
Abstract: This energy facade can be arranged on all buildings on the sides of the building upon which the sun shines. It serves to reduce the heat-energy requirement in the buildings concerned, by direct utilisation of the radiant energy striking the facade from outside, while at the same time providing high heat insulation against heat losses from inside outwards. This is achieved according to the invention by arranging an energy facade in front of a conventional outer wall (6) with large heat-storage capacity but relatively low heat-insulating capacity. The outer skin of this facade preferably consists of horizontally extending optical lenses (1) made of glass or plastic, which focus the incident radiant energy and conduct it onto absorber faces (3) arranged parallel to the lenses on the outside of the wall. A trapezoidal heat insulation (2), which tapers outwards and the boundary faces (4) of which are of reflective design and which likewise extends parallel, is attached between lens and solid wall. The radiant energy striking the outer wall and focussed by the lenses is thus conducted onto the absorber plate directly or via reflection on the faces of the insulation, depending on the position of the sun, and is fed into the solid wall by said absorber plate. Backflow of the energy thus fed in is considerably reduced by means of the heat insulation. <IMAGE>

Patent DE-3214469-A1 (DE)
Title: Plug socket with a flap cover which can be closed
Inventor: SCHMALENBACH WERNER
IPC: H01R13/447
Filed: 1982-04-20
Abstract: The plug socket has a flap cover (22) in which a cylinder lock (1) is inserted which protects the plug socket against unauthorised power consumption. Difficulties arise in designing the lock of the flap cover so that there is no hindrance for the plug in the region of the plug socket receptacle and, in addition, the flap cover is held in the closed position such that unauthorised opening can take place only by brute force. To this end, according to the invention, the closing clip (2) of the lock (1) is of one-armed construction and is provided with a hook (3). At its free end, the hook (3) engages behind a locking tab (5) which is located on the central axis (21) of the housing (23, 24), on the side of the flap cover (22) opposite the hinge (8). <IMAGE>

The holder serves to set up the rig for drying at the lakeside or on the beach before packing. To set up the rig on hard or gravelly ground, the holder can have a relatively thin, metallic spike or, in the interests of simple manufacture and a light weight for transport, can be made in one piece from plastic. <IMAGE>
Patent DE-3219007-A1 (DE)
Title: Control unit for the presetting of time ranges, adjustable in their frequency and in their length
Inventor: HIMBERT JUERGEN
IPC: G01P3/487
Filed: 1982-05-19
Abstract: The invention relates to a control unit for the presetting of time ranges, adjustable in their frequency and in their length, especially for presetting the injection period of piston engines. The length of the time range depends on the speed and/or power output necessary for the particular engine. The length of the injection period has hitherto been calculated by computers, by means of which the solenoids assigned to the injection nozzles are controlled. Disadvantages of this are the high technical cost of these computers and the fact that they can be used only to a limited extent for higher engine speeds. By contrast, these disadvantages are according to the invention avoided by a control unit essentially constructed on a mechanical principle, if the frequency is preset by means of a disc rotating as a function of the engine speed, which is provided with two pulse generators, and if two sensors, adjustable in opposition to one another in a circumferential direction and each interacting with one of the pulse generators, are arranged on a stator, which sensors are adjustable relative to one another in a circumferential direction and one of which emits a control signal corresponding to the start of the time range and the other a control signal corresponding to the end of the time range.
