Title: Device for detecting surface deviations
Inventor: RATCLIFFE EDWARD L
IPC: G01B7/30
Filed: 1981-02-12
Abstract: The invention relates to a device for detecting the deviation of a surface, structure or the like from a reference axis. A transducer which is sensitive to inclination is employed and has two impedances (11, 11') the impedance values of which vary differentially in accordance with the angle and the direction of inclination of the surface or of a unit on which the transducer is mounted. Two equal AC voltages which are, however, opposite in phase, are applied in each case to the two impedances (11, 11'), and the current obtained from each impedance is used in order to generate a DC voltage. The two DC voltages are compared in order to generate a differential DC voltage whose magnitude and sign depend on the angle and direction, respectively, of the inclination. <IMAGE>

Patent DE-3134600-A1 (DE)
Title: Drive circuit for a control amplifier
Inventor: ERBELE KURT
IPC: H03G11/00
Filed: 1981-09-01
Abstract: The output voltage of the control amplifier increases linearly with the input voltage until a certain threshold value is reached at which the output voltage of the control amplifier remains constant. The requirements that the range of levels is also arbitrarily limited downwards in spite of high input level transgressions, short-time disturbances in the signal variation should be absorbed and the circuit should be monolithically integrable are met by the fact that two impressed current sources are used as control current for the control amplifier (VR), that one current source (I1) determines the minimum gain of the control amplifier, that the second current source (I2) is withdrawn from the control current of the control amplifier (VR) via a parallel branch above a predetermined threshold of the output signal (Ua) of the control amplifier (VR) so that the latter keeps the output voltage (Ua) constant, that the parallel branch consists of at least one transistor, that the transistor is controlled by a threshold decision circuit (S) via a voltage divider, a diode and a storage element containing a capacitor, and that high-resistance resistors are replaced by diodes and transistors in a manner known per se. <IMAGE>

Title: Lashing and holding device having at least one strap
Inventor: VITT UDO DR
IPC: B66C1/18
Filed: 1981-10-16
Abstract: The invention relates to a lashing and holding device having one, but preferably a plurality of straps, each strap consisting of a one-piece fabric strip which is formed from strap portions arranged alternately in the longitudinal direction, on the one hand with a slit-like interspace provided between two fabric pieces and on the other hand with closed strap portions. Each strap so formed is provided naturally with loops for the insertion of transverse straps to form a netting or for the hooking of eyes and fittings which can be attached at any point without a single seam. Because there are no seams and in view of the almost universal tensioning possibilities, the article to be held and lashed is fixed especially securely, since, for example, there is no fear that a seam will tear.
Patent DE-3148334-A1 (DE)
Title: Double axle suspension for vehicles
Inventor: HONDA TETSURO
IPC: B60G5/04
Filed: 1981-12-07
Abstract: The double axle suspension for vehicles has four leaf springs (9, 10), two of which are supported on either side of the vehicle chassis, with their outer end being supported on a spring bearing (2, 4) and with their inner ends, which point towards one another, being pivotably supported by way of shackles (8) and a pivotably mounted differential beam (7) on a middle spring bearing (3). In order to keep the axle load essentially constant over as wide a lifting range of the wheel axles as possible, it is proposed that the axis of rotation of the differential beam (7) lie some distance above the line connecting the axes of rotation of the joints between the shackles (8) and the differential beam (7). It is also beneficial in this respect if the shackles are extended in comparison to conventional designs and, in the central starting position, are arranged inclined by approximately 10 to 15 DEG  to the vertical with the upper ends pointing towards one another. In order to obtain the desired uniform axle load even in braking and in reverse travel, pushrods (15, 16) are provided which at a relatively large distance below the centre axis of the wheel axles are pivoted to these. <IMAGE>

Title: Three-dimensional sliding toy
Inventor: OBERMAIR GILBERT DR
IPC: A63F9/08
Filed: 1982-02-05
Abstract: The surface of a sphere has subdivisions corresponding to the projections of the edges and corners of an icosahedron which is concentric with the sphere. In the projection of an icosahedron, spherical-shell triangles are formed between the subdivisions, of which, in each case, five can be twisted as a ring about their common corner, and each spherical-shell triangle forms part of three rings, so that it can be passed on from ring to ring by consecutive twisting of the rings. Rules can be devised for specific orders into which the sliding elements are to be brought. In order to guide the spherical-shell triangles, a guide rail lies between each pair of them, along the subdivisions, this guide rail guiding the edges of the spherical-shell triangles with mutual displaceability and itself being retained in the position of rest between two stationary guide members, and in the twisted position between one guide member and one of the other guide rails.

Title: Bogie for a rail vehicle
Inventor: HOLZ RUEDIGER ING GRAD
IPC: B61F3/04
Filed: 1982-06-09
Abstract: The bogie is characterised in that the customary frame is dispensed with and the wheels diagonally opposite one another are connected merely by means of diagonal members, on which the vehicle superstructures are supported in a spring-mounted fashion. The diagonal members are connected to one another by means of levers in such a way that they can move in relation to one another in the direction of travel; the vehicle superstructures are coupled to a central element of these levers. The new design permits a lightweight and simple bogie to be produced and is therefore particularly suitable for high-speed rail vehicles (over 150 km/h, in particular around 250 km/h).
Patent DE-3226166-A1 (DE)
Title: Automatic engine switch-off and restart system
Inventor: UEDA MASAHIRO
IPC: F02D29/02
Filed: 1982-07-13
Abstract: An automatic engine switch-off and restart system can be used to switch off the engine of a motor vehicle automatically in the presence of predetermined conditions and then start it again automatically under other predetermined conditions. In the case of such a restart procedure, a starter is switched off as a function of a signal which indicates that a predetermined engine speed value has been exceeded. For this purpose, the engine speed is determined by an engine speed transducer and a control circuit judges whether the engine speed determined exceeds the predetermined value or not. If the engine speed determined exceeds the predetermined value at which the engine will continue operating without help from the starter, the starter is switched off.
