Patent DE-3313805-A1 (DE)
Title: Proximity switch for railway applications
Inventor: SANDER HEINRICH DIPL ING
IPC: B61L1/08
Filed: 1983-04-15
Abstract: A magnetic switch (MS) which can be controlled by a permanent magnet (PM) which is secured in the proximity switch is integrated into the proximity switch (AS). The said permanent magnet rests with its poles against the travel rail (FS) from the side, its field lines meeting essentially over the travel rail. In this position, the magnetic switch has no influence on the functional behaviour of the proximity switch. If the proximity switch is disconnected from the travel rail, the field lines of the permanent magnet can no longer meet over the rail but rather meet at least partially over the magnetic switch (MS). This switch subsequently responds and markedly changes the oscillatory behaviour of the proximity switch. This change of the oscillatory behaviour can be expressed for example in a change in the current drain of the proximity switch or in a change in its oscillatory frequency. The detachment of the proximity switch from the travel rail is thus clearly detectable. <IMAGE>

Patent DE-3342066-A1 (DE)
Title: Apparatus for the continuous treatment of textile material
IPC: D06B21/00
Filed: 1983-11-22
Abstract: In an apparatus for the continuous treatment of textile material, a drier is arranged at the concluding end. The moist air produced during drying is expelled by way of a waste-air shaft. The eliminated quantity of moist air is replaced continuously by fresh air. In a perforated cylinder drier, the issuing textile material is cooled by means of the cold fresh air, the fresh air becoming heated. To utilise the energy contained in the waste air, it is proposed to feed this to the preceeding washing appliance, for example by passing the washing fluid by way of pipelines into a heat exchanger in the waste-air shaft of the drier, heating it there and returning it to the washing machine.

Title: Electrical gas-blast circuit breaker
Inventor: MARIN HEINER
IPC: H01H33/18
Filed: 1983-12-02
Abstract: In an electrical gas-blast circuit breaker, a contact system is provided which consists of at least one stationary (1) and one moving switching piece (3). At least one of the two switching pieces (1, 3) is constructed to be hollow in order to dissipate switching gases. When switching off under load, an arc is drawn between the two switching pieces (1, 3), which arc is blasted by a piston-cylinder arrangement, which surrounds the contact system, in order to generate an extinguishing gas flow. Two electrodes (9, 11) are connected in series with the contact system, of which electrodes the one (9) is arranged in a stationary manner and the other (11) in a moving manner, and is driven jointly with the moving switching piece (3), in a rigidly coupled manner. The electrodes (9, 11) are used for generating an auxiliary arc in an arcing space (12) which is provided outside the piston-cylinder arrangement (4, 5), is filled with compressed gas, is closed during the switching-off process and has a moving wall part (4b) which is connected to the moving part (4a) of the piston-cylinder arrangement (4, 5). In order to design the drive such that it is independent of the magnitude of the current to be switched, the moving part (4) of the piston-cylinder arrangement (4, 5) and the moving wall part (4b) of the arcing space (12) can be moved against the force of a restoring spring (16) only by the energy of the auxiliary arc, and are mechanically decoupled from the drive (8) of the moving switching piece (3) of the moving electrode (11). <IMAGE>

Title: Transfer device for work pieces
Inventor: IKEOKA NAOAKI
IPC: B21D43/05
Filed: 1983-12-27
Abstract: A transfer device for advancing essentially flat work pieces through a succession of pressing stations of a transfer press comprises two transfer bars which extend parallel to one another at a distance from one another and, for the purpose of grasping, lifting and advancing the successive work pieces from one pressing station to the next, can be moved backwards and forwards in the longitudinal direction as well as upwards and downwards and towards and away from one another. When grasping the work pieces, the transfer bars are moved towards one another with the aid of a rack and pinion drive. To adapt the minimum spacing of the transfer bars to different widths of work piece to be grasped, a tandem cylinder arrangement (86) comprising at least two fluid-actuated cylinders (92, 94) is provided between a cam mechanism driving the rack and pinion drive and the rack of the said drive. At least one cylinder (92, 94) has two pistons (100, 102) movable independently of one another, the cylinder arrangement thus comprising overall at least three pistons (100, 102, 114). The travels of the individual pistons are preferably different from one another. By selective pressurisation of the fluid chambers (104, 106, 108, 110, 116, 118) bounded by the pistons, numerous combinations of piston positions can be set, allowing the total length of the cylinder arrangement (86) and hence the minimum spacing of the transfer bars to be...in a simple manner in small steps ...

Patent DE-3400895-A1 (DE)
Title: DC chopper control arrangement
Inventor: URBANKE CHRISTIAN DR
IPC: B60L7/22
Filed: 1984-01-12
Abstract: A DC voltage source (Ed) supplying energy (for example a DC motor in braking mode) having a downstream-connected energy store (inductor Ld) is short-circuited in order to charge the store via the main valve of a controller, and is connected via a diode D to an energy-consuming DC voltage source (supply voltage Un) for charging, which DC voltage source can, however, also be short-circuited via a discharge thyristor BT and a discharge resistor RB. A GTO thyristor is used as the main valve of the controller. In order to ensure that the discharge thyristor BT is blocked when said GTO thyristor is switched off, a discharge capacitor CB is connected in parallel with the discharge resistor RB. When the discharge thyristor is turned on, this capacitor charges, and when the controller is turned on, it discharges and reliably turns the discharge thyristor off. <IMAGE>
Patent DE-3410914-A1 (DE)
Title: Pruning saw
Inventor: VEIL WALTER
IPC: A01G3/08
Filed: 1984-03-24
Abstract: So that branches of a certain thickness can be safely sawn off at a distance of, for example, two to three metres, the pruning saw has a circular saw blade (1) which can be driven by means of an electric drive motor (2) and projects into a branch guide (8) widening from outside to inside or at least largely passes through this branch guide (8) in the transverse direction. On account of the branch guide widening slightly, jamming is impossible when pushing the pruning saw forward towards the branch. In addition, the pushing forward of the branch is assisted by the automatic pulling-towards effect during the sawing. <IMAGE>

Title: Detachable protection for the heel part of shoes
Inventor: FLORJANCIC PETER
IPC: A43B23/30
Filed: 1984-07-06
Abstract: During driving, the accelerator and the brake pedal are operated with the right foot in such a manner that the shoe, with its rear heel edge as tipping edge, is applied, inclined or raised. As a result, the leather on the heel part of only the right shoe is heavily worn. The invention envisages, to counter this, a detachable protection in the form of a protective cap (5) which covers the heel part at least in the rear region, is open at the top at (7) and can be closed over the instep of the shoe with fastening means. To this end, the protective cap (5) expediently has a support lying in the pulling direction of the fastening means (6), which can be e.g. a horizontal bottom part of the cap (5), which part lies under the heel (4) of the shoe. <IMAGE>

Title: Measuring device for an adjustable tool of a numerically controlled machine tool
Inventor: BECK HANS-WERNER DIPL ING
IPC: G05B19/401
Filed: 1984-11-24
Abstract: A measuring device of an automatic adjusting device for a rotating tool of a numerically controlled machine tool is described. Two measuring sensors are provided, of which one measures the actual position of the tool cutting edge and the other measures the actual position of a reference point provided on the tool holder. If the actual difference determined here deviates from a predetermined desired difference, an analysing circuit transmits a correction signal to an adjusting device for the tool cutting edge. In order to take into account a misalignment of the tool holder, designed for example as a boring bar, in the direction of the tool cutting edge and away from the tool cutting edge, the tool holder is provided with a second reference point which is offset by 180 DEG  from the first reference point. By means of these two reference points, an averaged reference-value signal is produced which is used for determining the actual difference. <IMAGE>

Title: Method and device for guiding and collecting light in photometry or simular
IPC: G01N21/47
Filed: 1984-12-24
Abstract: A method and device for guiding and collecting light emanating from a light source and fed as incident primary beam to a specimen or similar material to be measured is/are intended to optimise the guidance and collection of the light. This purpose is served by a method in which the material to be measured is arranged in a focal point of a reflecting surface constructed at least as half an ellipsoid of revolution or paraboloid of revolution, and beams leaving this material to be measured are broken on the reflecting surface. In this case, the primary beam is to be irradiated directly into the centre of the material to be measured. If the material to be measured is surrounded by a paraboloid of revolution, the measuring light is rendered parallel and/or focused without the application on a lens system. A device of the type mentioned at the beginning is distinguished in that at least the material (14) to be measured is surrounded by a reflecting surface in the form of at least half an ellipsoid (13) of revolution or a paraboloid of revolution, and the material (14) to be measured is arranged in the focal point (F1) thereof. In another device, the measurement chamber (12) is bounded by a reflecting surface in the form of an ellipsoid (13) of revolution, in one focal point of which the light source (3) is provided and in the other focal point of which the material to be measured is provided. <IMAGE>

Patent DE-3513073-A1 (DE)
Title: Fixed blade displacement machine
Inventor: WILLIMCZIK WOLFHART DIPL PHYS
IPC: F01C3/06
Filed: 1985-04-12
Abstract: The great versatility of the already proven fixed blade displacement principle permits new variants, described here: the new bladed rotor is given a triangular, rectangular or pentangular cross section, the faces of the blades being of circular arc shape or straight. The circular arc-shaped recesses may be inwards, outwards or inwards and outwards or closed (round recess). Irrespective of this, the cross sectional shape of the rotationally symmetrical working chamber can be varied as required. Either blades rotate in an annular groove or the entire bladed rotor rotates in a turned recess and itself fills the internal chamber. This turned recess may be, for example, conical, cylindrical or of a spherical shell shape. The latter variant permits a swivelling of the axes of rotation of the bladed rotor, by means of which the "swept volume" is adjusted. The possible uses range from a simple water pump through water hydraulics, adjustable hydraulic pump or motor through to the compressed air motor and compressor.
