Patent DE-3234800-A1 (DE)
Title: Thrust gyro
Inventor: KUEMMEL PETER DR
IPC: G01C19/02
Filed: 1982-09-20
Abstract: By using the rapid counterrotation of masses that have a centre of rotation and are mounted immediately next to one another it is possible artificially to achieve a displacement of the centre of mass in the self-enclosed system of the central frame Fig. 5; ISBNs 3-921 291-003, -01-1, -02-x and ISSN 0720-9614, prior art since 1970. Rotating in the thrust gyro instead of the solid masses having a centre of rotation in the form of solid cylinders are cardan rings 2 in which, in turn, rotating masses 1 rotate at maximum speed as the gyros. The rotating gyros 1 impose considerable resistance to the drive wheels 3 of the cardan frames 2 more than the inertia of solid masses. By virtue of the stabilising forces of the gyros 1, the cardan frames 2 can counterrotate only given the expenditure of a large force of the drive 4. The precession forces occurring as a counterreaction not only vanish in the bearing friction. They appear as deflection of the gravitational field about the frame 5. As a result, an appreciable displacement of the centre of mass is achieved which generates a forward drive of the system in the direction of the arrow 6. The thrust gyro is suitable for drives of any type, in particular in space. <IMAGE>

Patent DE-3240159-A1 (DE)
Title: Diagnostic composition and test method for detecting crystallisation effects in biological systems
Inventor: SCHNEIDER HANS-JOACHIM PROF DR
IPC: G01N33/50
Filed: 1982-10-29
Abstract: A slide is coated with gel. Two opposite starting holes are each punched into this gel. On introduction of solutions of calcium chloride or ammonium oxalate into two of these holes, the ions migrate towards one another and, at the meeting point, a zone of calcium oxalate crystals is produced. The crystal density and width of this zone are measured photometrically. If solutions to be tested, such as urine, are simultaneously introduced into the other two holes, their effect on the crystallisation of calcium oxalate, either as promotion or inhibition, can be determined photometrically. A typical extinction profile is produced, and the ratio of the height and the width at half the height of the control plot and inhibitor plot yields the so-called inhibitor index. This system can be applied to various crystal formers and inhibiting or promoting substances. It is employed in medicine in order to detect the crystallisation tendency or the inhibitor capacity of the urine of patients with urinary calculi. This means that patients at risk can be identified, just like the efficacy of therapy and prophylaxis of urolithiasis.

Patent DE-3304996-A1 (DE)
Title: Contact nozzle
Inventor: SCHOENAU ROLF
IPC: B23K9/12
Filed: 1983-02-14
Abstract: A contact nozzle, having a shaft which is equipped with retaining elements such as a threaded attachment, of welding heads or welding guns for arc welding, whose hole, which guides wire-shaped electrodes and switches the current transfer to said electrodes, has at least one bend, is intended to be developed such that, in its external shape, it is matched to conventional contact nozzles and, in the same way as said nozzles, emits the electrode wire in the direction of its centre axis, but ensures correct current transfer with a constant, low contact resistance from the nozzle to the electrode wire, with a long service life. This is achieved in that the shaft and the retaining elements, for example the threaded attachment, as well as the opening section of the hole which is passed through by the electrode wire, run in an extended manner on the same axis, while at least one hole section is curved, or, better, more than one hole section runs curved differently.
Patent DE-3308747-A1 (DE)
Title: Locking element
Inventor: MANGOLD ANTON
IPC: B60C27/10
Filed: 1983-03-11
Abstract: The invention relates to a locking element for tension elements (e.g. chains) on anti-skid chains with a passage at which a slot begins. After the pulling process is over, the longitudinally positioned chain element comes to lie in the slot and slipping back counter to the direction of the arrow-is prevented by the transversely aligned chain element. For the purpose of locking, the locking element comes to lie on the guide ring. The locking element remains uninfluenced by the chain network, which is under tension, because it is loosely attached to a chain element, e.g. the outer bracket, by means of a bracket.
Patent DE-3313381-A1 (DE)
Title: Arrangement for monitoring the hydraulic working pressure of a consumer
IPC: F15B11/028
Filed: 1983-04-13
Abstract: The arrangement serves to monitor the hydraulic working pressure of a consumer and has a pressure-control valve which lies in a feed line from a hydraulic unit to the consumer and with which the respective working pressure can be set. Arranged in the feed line is an operating device which is provided with an operating piston and interacts with an operating member. Attached to the operating device is a control device which is connected with one of its connections via a control line to the feed line and is connected with its other connection via a feed line to a return line which leads from the consumer to the hydraulic unit. If the hydraulic pressure falls below a predetermined value, the control device displaces the operating piston to trigger an operating signal. Since the control device is attached with both connections to the feed and return line from the hydraulic unit to the consumer, there is a direct connection to the hydraulic feed line, so that a pressure drop can be taken directly from the feed line. The design of the pressure-control valve for the operability of the arrangement is of no importance here.

Title: Self-priming hydropneumatic spring strut with internal level-control system
Inventor: BECK HUBERT
IPC: B60G17/044
Filed: 1983-05-03
Abstract: The aim was to create a simple level-control device, which for the same overall dimensions permits a greater shock absorber lift and the non-return valve of which is easy to fit and can be readily repaired from outside in the assembled condition after discharging the pressurised gas. In order to solve this problem, it is proposed that the non-return valve be arranged in the end area of the piston rod emerging from the working cylinder, the valve body, with oil passages, having an outside diameter equal to the inside diameter of the hollow piston rod and in the fitted state being permanently fixed by way of a snap connection to the control sleeve and a vent plug inserted in the piston rod.
Patent DE-3317892-A1 (DE)
Title: Rotation-speed controller for a fan motor
Inventor: DENKE FRANK DIPL ING
IPC: H02P7/22
Filed: 1983-05-17
Abstract: Rotation-speed controllers for fan motors are generally constructed using modern electronic components, for example thyristors. Phase-gating circuits are preferred, but these produce disturbing noise because of the intermittent operation. As a result of the combination of a series circuit, constructed from a plurality of resistors, and a switch which alternately short-circuits individual resistors, a rotation-speed controller is created which, although operating in a stepped manner, is, however, virtually continuous because of the large number of its steps. The series circuit (15), which consists of only three resistors (R1, R2, R3) allows the implementation of six switching stages, as a result of the clever construction of the switch (20), and thus leads to a surprisingly simple and reliably constructed rotation-speed controller. <IMAGE>

Title: Portable machine for grinding (rectifying) cylindrical surfaces
Inventor: GARCIA CARLOS MANUEL HIERRO
IPC: B24B23/00
Filed: 1983-06-29
Abstract: Portable machine for grinding (rectifying) cylindrical surfaces, consisting of a device for transfer of movement having a pneumatic motor (2), which drives chain wheels (15) subdivided in two halves, which rest on the surfaces which are to be rectified by means of supports (13) which can be adjusted to the diameter of the part to be rectified, the chain wheels (15) being connected rigidly to each other through connection rods (16) which carry the grinding (rectifying) device which consists of an electric motor, to which is coupled a grinding stone (25) which can carry out feed, plunge and translation movements. Electrical conductive rings (23) subdivided into two parts are embedded in the outer portion of the chain wheels (15) which are subdivided into two isolated parts. Means are arranged between the two adjustable front supports (21) which make it possible to grind (rectify) the grinding surface of the grinding stone (25). A fibrous section is coupled with the connection rods (16) and permits a continuous rotational movement with a speed varying between 150 and 300 rpm, which allows the finish machining of the surfaces (24) to be ground (rectified). <IMAGE>

Patent DE-3325946-A1 (DE)
Title: Apparatus and method for grinding and polishing, in particular metal objects, with a flexible tool
Inventor: HUBER XAVER
IPC: B24B49/16
Filed: 1983-07-19
Abstract: In order always to change (retract or advance) the distance between tool (20) and workpiece (1) in such a way that the rate of metal removal is as constant as possible, i.e. the applied pressure of the flexible tool (20) on the workpiece (1) is appropriate, the tool-workpiece distance is automatically adjusted by an analog-digital controller. To this end, the power input of the drive motor (2) is tapped and, after comparison with a set desired value, is used to produce positively or negatively graded pulses. The pulses of corresponding sign are added up in one of the counters (67, 67') and are used to trigger an advance or retract signal either at the set maximum of a counter (67, 67') or in accordance with a time function element (70). The tool (20) is advanced or retracted by the servomotor (5) according to this signal. The duration of this adjustment is set by a time function element (69). Such relatively constant machining can take place even in the case of irregular workpieces (1) which are moved bidirectionally (rotation about A and feed along B) by the work holder (10). <IMAGE>

Patent DE-3332585-A1 (DE)
Title: Cat's toilet
Inventor: GERHARDT WOLFGANG
IPC: A01K1/01
Filed: 1983-09-09
Abstract: The cat's toilet, which has been contested for a year, reduces the amount of cat litter required after re-adaptation to a small fraction of the estimated 2 kg a week which are otherwise usually necessary. It is naturally advisable to take into account the behaviour of the cat and to adapt the quantity of cat litter to that behaviour if necessary. By regular removal (every 2nd day) of the upper, soiled layers of newspaper - the consumption of cat litter remains low with the desirable thin application (one handful) - the cat's toilet can be kept permanently clean.

Title: Safety switching device for electrically operated apparatuses, especially for domestic purposes, workshops, gardens or the like
Inventor: GIMELLI SAMUEL
IPC: H01H3/20
Filed: 1983-10-12
Abstract: In an electrically operated apparatus, especially for domestic purposes, workshops, gardens or the like, a push-button switch (5) is provided where the thumb can reach it from the handle in order to switch the power supply from the mains or from accumulators on and off, which push-button switch has a release knob (20) allocated to it, at a distance from it and in a plane which is inclined with respect thereto, which release knob (20) can likewise be pressed down and whose locking bolt (18), which is directed towards the push-button switch, engages with a stop surface (16) of the push-button switch in the original or switched-off position, in order to block the pushing-down movement of the push-button switch, while this locking bolt releases the stop surface (16) when the release knob (20) is pushed down in order to allow the push-buton switch (5) to move freely. This interaction of the two switching devices thus requires the assistance of the hand which is otherwise free for switching the drive motor on, and in this way prevents injuries to this hand resulting from carelessness during handling of the apparatus. <IMAGE>

Title: Process and reactor for the catalytic reaction of hydrogen sulphide to give elemental sulphur
Inventor: HEISEL MICHAEL DR
IPC: C01B17/04
Filed: 1984-02-02
Abstract: A process is described for the catalytic reaction of hydrogen sulphide, which is contained in a gas stream, in the presence of sulphur dioxide to give elemental sulphur. The gas stream is preheated and passed over a catalyst bed to achieve the reaction. The vaporous sulphur produced is condensed by cooling, and the gas stream freed of sulphur compounds is drawn off. In order to achieve a sulphur yield close to the theoretically possible value, while keeping the pressure loss at a minimum and reducing the investment and operational costs, it is proposed to pass the gas stream from the bottom to the top over a catalyst bed operated quasi-isothermally, to cool the catalyst bed internally by means of a coolant, to pass the gas stream after the reaction into a condenser from below, to cool the condenser internally and to withdraw in liquid form the sulphur deposited on the condenser surface.

Title: Elastomer chain tensioner for tracked vehicles
Inventor: MENKHOFF KARLHEINZ
IPC: B62D55/30
Filed: 1984-02-09
Abstract: The invention relates to a tensioning device, preferably for tracked vehicles, but also for other tensioning units which provide flexible and shock-absorbing resilience, are able to operate in temperatures of -45 DEG C to +60 DEG C, the spring power of which can be altered in the fitted state and which must be extendable in order to alter the tensioning displacement, for example to compensate for the wear of a chain, and the spring power of which is applied by means of a compressible viscous elastomer and consequently does not relax explosively when springing back but instead presses back the spring plunger slowly and with end-position damping. In the event of extreme temperature fluctuations, the tensioning device is kept at the appropriate temperature by recharging the prestressing pressure of the elastomer or, in the event of extreme minus temperatures, by for example electrical heating rods.

Title: Heat-pump function accumulator
Inventor: LUEESSE HORST
IPC: F24D19/10
Filed: 1984-07-23
Abstract: Heat-pump function accumulator (HPFA) as a method for collecting and distributing heating heat, in which all otherwise known function and behaviour sequences, such as in heat pumps, large-volume layered accumulators as well as regulating and control members, are designed to be matched to one another and optimised in detail in such a manner that a simple, new, comprehensive and effective method for exceptionally economical, low-loss and environment-friendly heating heat provision and distribution arises therefrom. As a result, heat consumption which occurs cyclically in level and length of output and heat production and recovery running asynchronously in relation thereto can be collected and distributed from heat which would otherwise be lost. The annual cycle and the heat pump operated with alternative current generation are in this case the optimal use possibilities.
