Patent DE-3533839-A1 (DE)
Title: Magnetic drive having three stable positions
Inventor: RUBEL ERICH DIPL ING
IPC: H01F7/122
Filed: 1985-09-23
Abstract: In the case of a magnetic drive which is suitable for use especially as an electromagnetic control device for door operating systems, it is proposed to combine two coils with at least one permanent magnet such that, when the two coils are driven with direct current in a suitably directed manner, an armature and, in a corresponding manner, a pneumatic actuating cylinder, which is controlled by said armature, can be controlled both into two positions which are stable even when no current is flowing and which describe a venting state and a ventilating state and, in addition, may assume a third stable intermediate position in which the valve function of pressure maintenance is implemented. <IMAGE>

Title: Automatic reverse steering system for passenger vehicles with trailer
Inventor: SCHERBER KARL
IPC: B62D13/06
Filed: 1985-10-29
Abstract: In order to simplify the difficult reverse steering of a trailer, the complicated counter steering takes place fully automatically and the manual steering which has to be performed by sight and according to a natural feeling for the steering has the behaviour of a vehicle without trailer and can even be performed without difficulty by a child as in, by way of comparison, a remote-controlled model with the same steering technique, without the trailer ever being able to leave its predeindicationined reverse travel route or even adopt an askew position. The variants, presented in four different embodiments, of the automatic control with internal and external counter steering technique with single-axle and double-axle trailers, with mechanical and electrical control technology and, finally, for vehicles which are to be moved backwards and forwards are described. A special auxiliary servo drive whose drive power is derived from the wheel movement is proposed. By means of the interaction of a plurality of potentiometers which act as angle value transmitters, the control voltage for the counter steering servo drive or auxiliary servo drive is prepared in the electronic component and the property of sliding steering, which is immune to oversteering, is transmitted to the control potentiometer. An automatic angle matching ensures minimum tyre wear.
Patent DE-3544294-A1 (DE)
Inventor: LINDEMANN KLAUS
IPC: F02D41/22
Filed: 1985-12-14
Abstract: A system for automatically overriding operator control of engine power delivered to the drive wheels of a motor vehicle when a wheel slip condition is detected during vehicle acceleration. A pneumatic actuator in the engine fuel control circuit is operated in a controlled manner to cause the engine fuel lever to initially decrease power at a relatively fast rate and then at a relatively slow rate to alleviate the wheel slip. Once the wheel slip condition is corrected, the actuator is reset in a controlled manner, which allows the fuel lever to restore engine power, initially at a relatively fast rate and subsequently at a relatively slow rate, such rate controlled adjustment of engine power during each wheel slip control cycle providing less cyclic control of the wheel slip correction process, and accordingly a smoother acceleration.
Patent DE-3606289-A1 (DE)
Inventor: FLEMMING GUENTER DR
IPC: B22D11/04
Filed: 1986-02-27
Abstract: A method for concluding the operation of the continuous casting of strip metal comprising the steps of casting said strip in a narrow slotted strip shaped continuous casting mold having a flared inlet pouring zone necking down to a distal zone in which the walls of the mold are parallel and spaced apart by substantially the desired cross-sectional shape and dimensions of the strip being cast, pouring liquid metal through a pouring tube having an orifice into said flared zone, and controlling the pouring rate thereof, continuously detecting and monitoring the instantaneous surface level of the metal bath in said mold, withdrawing the casting from the distal end of said mold, and controlling the rate of withdrawal, adjusting the pouring rate and withdrawal rate so that the level of the metal bath is at a maximum height for said mold when in normal operation, continuously sensing whether or not there is present downstream of said mold evidence of the liquid core of said cast strip, reducing the pouring and withdrawal rates for concluding the casting to a rate at which the liquid core of the cast strip is near to but downstream of the mold and at which the metal bath level remains constant, terminating said pouring while continuing said withdrawal, whereby the metal bath level descends rapidly toward the neck end of said flared zone, reducing the withdrawal rate when the metal bath level is close to the lower end of the flared zone to a rate at which the upper surface of the metal bath can congeal sufficiently for further processing downstream by the time it reaches the end of the distal zone, and thereafter withdrawing the casting.

Title: Runner for example for a sledge for snow or ice
Inventor: UEHLIN JUERGEN DIPL ING
IPC: A63C5/00
Filed: 1986-02-28
Abstract: The intention is for a runner, which is made of hard material, of a sledge, such as, for example, the runner of a bob-sleigh, to be steerable. For this purpose, the runner is not divided with one part being swivelled for the steering but rather the runner can be bent in a directed manner over its length for steering the sledge parallel to the underlying surface. When steering or cornering the runners no longer slip laterally but rather the runner draws a clean line which it has itself pressed into the underlying surface on which a sledge can slide. <IMAGE>

Patent DE-3630486-A1 (DE)
Title: Scrubbing water treatment process for simultaneous SO2/NOx wet scrubbing
Inventor: HOELTER HEINZ DIPL ING
IPC: C02F1/70
Filed: 1986-09-08
Abstract: In the simultaneous SO2/NOx wet scrubbing from flue gases, when an iron(II) complex with ethylenediaminetetraacetic acid or sodium salts thereof is used, a nitrosyl complex is formed with the NO, which is regenerated via sulphite ions. Both reactions proceed in parallel in the flue gas scrubber. At the same time, depending on the process conditions in the reduction of the nitrosyl complex, readily volatile sulphur-nitrogen compounds are also formed. Various processes are known for ejecting the dissolved reaction products from the scrubbing water which are, however, comparatively complex and laborious. It has now been found that the scrubbing water regeneration can be simplified and carried out more inexpensively in that, for regeneration, the water ejected from the scrubbing water circulation of the SO2/NOx simultaneous wet scrubbing enters into the EDTA precipitation vessel. Addition of a reducing agent, preferably sodium dithionite, completely reduces the iron(II/III) EDTA to Fe(II)-EDTA in order subsequently, by addition of sulphuric acid to a pH in the scrubbing solution of pH 0.5-3.0, to precipitate the EDTA in the scrubbing solution from the Fe(II)-EDTA complex. The resulting amounts of SO2 are returned via the pipe to the simultaneous scrubber.

Title: Automatic safety belt emergency release system
Inventor: BODEN HORST PROF DR SC TECHN
IPC: B60R22/32
Filed: 1987-02-24
Abstract: The invention relates to an automatic emergency release system for a safety belt fastener for installation in conjunction with a safety belt system in aircraft, watercraft and ground vehicles, which system automatically releases the fastener or fasteners in the event of an impact of predetermined magnitude after a presettable time constant has elapsed. The object of the invention is to provide an emergency release system for a safety belt system, which, in addition to the customary actuation by hand, provides for release of the belt fastener in the event of an accident in such a way that the fastener tongue is only released after a time lag in the case of exceeding or dropping below predetermined values. According to the invention, the object is achieved in that an electromechanical lock in the belt fastener is actuated indirectly by a restorable time member which is known per se, and the restoring input of the time member is connected to parallel contacts of a delay sensor which registers the delay in three planes (Figure 2). <IMAGE>

Inventor: MOELLENDORF MANFRED DR
IPC: G01B7/012
Filed: 1987-03-13
Abstract: A probe array for coordinated measuring machines, manipulating devices or the like is proposed in which the position of the probing element (204) for scanning the surface (203) of the workpiece (202) to be measured can be measured with respect to the probe array (205) by means of a position measuring device (223) which contains a permanent magnet (224, 10, 80) and magnetoresistive sensors which are arranged in a detection device (226, 12, 82). Special arrangements of the sensors (16, 18, 20, 22, 60, 62, 64, 66, 120, 122, 124, 126, 130 to 137) taking particular account of the directions of the premagnetisation fields (48, 50, 52, 54, 71 to 74, 145 to 152) present given the magnetoresistive elements enable three-dimensional position measurements at high resolution for an arbitrarily large area (11, 86). An advantage is the cost-effective realisation of the detection device (12, 82) as a component using thin-film technology. The probe array (205) according to the invention permits a rapid measuring cycle in cooperation with the coordinate measuring machine (201). Rest position, hysteresis effects, the effect of aging and gravitational influences are taken into account in a signal processing arrangement (36, 118, 227). <IMAGE>

Patent DE-3708797-A1 (DE)
Title: Braking trolley
Inventor: KLAER PETER DR ING
IPC: B61H7/12
Filed: 1987-03-18
Abstract: For transporting loads, also preferably for transporting headway support stages for underground mining and tunnelling, brake trollies are provided which each have pairs of clamping jaws which are arranged in the protective housing and act in opposition to one another. The clamping jaws of the pairs of clamping jaws can be pivoted in each case about vertical axes and have extensions on which the spring and the release cylinder which are preferably in two components engage at the end sides, the clamping jaws being pivoted into the clamped position or into the released position by means of the said spring and release cylinders. By virtue of their shape and the T elements which are pivotably attached to the clamping jaws at the front they rest in a sealed fashion against the web of the monorail conveyor and thus forcibly bring about the braking process. Springs and release cylinders are attached horizontally and in parallel with respect to the axis of the rail so that a very small overall height of the braking trolley is produced. In addition, favourable application of the forces is achieved by means of the positioning of the individual assemblies, the application being still further improved by virtue of the fact that in each case there are two pairs of clamping jaws acting in opposition. The fact that the halves of the springs are fixed to alternate sides of the side frames prevents the spring floating and thus ensures high operational reliability of the brake trolley. <IMAGE>
