Patent DE-3131942-A1 (DE)
Title: Carrying device for skis
Inventor: HOCHHOLZER RAINER
IPC: A63C11/02
Filed: 1981-08-12
Abstract: A carrying device (1) for skis (5) has a flexible carrying piece (3), preferably in the form of a strap made of plastic or textile material with fastening devices (4) at the ends, with which fastening devices the carrying piece (3) can be attached to a ski (5) or to a pair of skis. For this purpose, for example, dowels (6) or similar counter-holding means may be provided on the ski. By means of the carrying device according to the invention, it is possible to carry a ski (5) or a pair of skis, if appropriate even a plurality of pairs of skis, in a similar way to a case, the carrying device (1) taking up only very little storage space and therefore being able to be taken along, for example in an anorak pocket, every time the skis (5) are used. The carrying device (1) is thus always immediately available without restrictions as soon as the skis (5) are taken off.   <IMAGE>
Patent DE-3135287-A1 (DE)
Title: Floating dredger
Inventor: HERMS PETER
IPC: E02F3/92
Filed: 1981-09-05
Abstract: A floating dredger contains a boom attached to the hull. A drivable clearing worm is arranged on the free end of the boom and can be lowered to the bottom of the stretch of water in order to convey mud or other bottom substances to the suction opening of a suction pipe which draws off the mud by means of a suction pipe and directs it, for example, into the interior space of the hull. In order to permit considerable areal degradation with as little turbulence as possible and in order to also be able to clean extensive stretches of water, the clearing worm is orientated in the longitudinal direction of the boom and performs together with the boom a reciprocating clearing movement about a fixed vertical axis.
Patent DE-3141468-A1 (DE)
Title: Brake booster and back pedal brake for bicycles with dérailleur
Inventor: PAESELT ARTUR
IPC: B62L5/00
Filed: 1981-10-20
Abstract: The invention can be used for additional boosting and as a sole back pedal brake. Dérailleurs do not permit power transmission through the chain when pedalling backwards. Therefore, the force of the back pedalling is taken up by the large chain wheel. The dérailleur keeps the entire chain constantly taut and therefore at the same time pulls backwards and thus blocks the brake jaws since the chain can only be moved forwards again if the - now braked - running wheel were to turn forwards. Therefore, at the start of back pedalling, backwards movement is prevented by stopping the pinion. The tensioning lever releases sufficient chain for back pedal braking. The other rim brakes brake much more weakly in wet conditions than in dry conditions. The impetus for this work arose from personal experience. According to the invention, imperfect braking is improved to a very great extent and can possibly be perfected if the existing brakes are changed in accordance with the now greater force.
Patent DE-3141714-A1 (DE)
Title: Temperature-compensated integrated semiconductor circuit
Inventor: IWAHASHI HIROSHI
IPC: E05F15/632
Filed: 1981-10-21
Abstract: A current-controlling or current-regulating metal oxide (MOS) transistor is connected in a circuit between a power supply line and a MOS circuit. A control signal whose level depends on the relevant temperature in a particular case is supplied to the gate terminal of the MOS control and regulation transistor to compensate for the current flow reduction due to the lower mobility of the minority charge carriers at high temperatures. The response time of the MOS circuit is rendered less temperature-dependent as a result of the current compensation.

Title: Stellar radial adjuster in disc units and units of flexible discs
Inventor: KAPUN MATJAZ
IPC: G11B19/20
Filed: 1982-02-05
Abstract: The stellar radial adjuster in disc units and units of flexible discs represents a new type of design for the adjustment of magnetic heads, the type of organisation of the recording and of the access to the data required also having been altered. By increasing the number of magnetic heads used and a new guidance of them, a significant increase in disc capacity and the response ratio as well as a reduction in the data access time and recording time are achieved. For driving the adjuster, a stepping motor or a moving coil may be used. <IMAGE>

Inventor: FELDMANN JOACHIM ING GRAD
IPC: F16D55/10
Filed: 1982-02-06
Abstract: A disc brake having a brake shoe wear compensating mechanism in which the sealing gaskets for the operating chamber formed between a pair of spreading members are arranged to be elastically deformable during a brake application, so as to exert a return force during a brake release. A joining element is provided between the spreading members, which utilizes a spring and the friction connection between the joining element and one of the spreading members to exert a return force independently of the return force exerted by the sealing gaskets, to thereby assure a sufficient brake release stroke.

Patent DE-3225504-A1 (DE)
Title: Cascade rectifier transformer
Inventor: STADLER BERTOLD DR
IPC: H02M7/10
Filed: 1982-07-08
Abstract: The invention is based on the aim of eliminating the damaging layer capacitance of the secondary winding of high-voltage transformers which are used for rectifiers, or greatly to reduce it, so that the layer capacitance no longer essentially determines the upper limiting frequency, as in the past. The invention can be used with advantage in conjunction with switched-mode power supplies for generating high DC voltages. If the arrangement is operated with an impressed square-wave current, then the arrangement provides a constant current at the output with little ripple. The arrangement consists of a transformer having layers which are wound in the same direction with a constant number of turns per unit length, the connection of the winding ends which are led out of each layer being connected in a diagonally opposite manner to diodes in such a manner that the layers are connected in series in an alternating direction in each half cycle of the AC voltage. In consequence, a DC voltage potential of the magnitude of a layer AC voltage is produced between the layers, which potential fluctuates to a greater or lesser extent about a mean value, depending on the behaviour of the AC voltage with time. In the ideal case of a square-wave layer AC voltage, this fluctuation disappears. In contrast thereto, in the case of an electrical layer connection between the layers, at least the AC voltage of one layer would occur and hence the layer capacitance would reverse its charge periodically. The invention allows various possibilities for connection to a load: connection of the load for example via the centre points of the first and final layer, their connection via diodes from the winding ends of the first and final layer. In addition, the winding starts can be used for potential control. Capacitors between the ends and/or starts of the adjacent layers, for smoothing purposes, have no influence on the limiting frequency of the arrangement, since they increase only the static layer capacitance.

Filed: 1982-09-28
Abstract: The attempts to date to imitate the shades of gold and of its alloys by means of alloys of less precious metals have been unsuccessful in particular because the materials did not have sufficient resistance to tarnishing. For the production of articles such as fittings, watch cases, mountings, jewellery, cutlery, cups and the like, it is now proposed to use a copper alloy with 1 to 7% of tin and 1 to 7% of aluminium, the sum of the percentage contents of aluminium and tin not exceeding 10%, and the remainder being copper and including unavoidable impurities arising from the production.

Title: Ink drop copying device
Inventor: BOBICK THOMAS WALTER
IPC: H04N1/195
Filed: 1982-10-05
Abstract: The ink drop copying device comprises a plurality of angled ink drop print heads for reproducing an original. Each print head generates a line of drop streams which are individually controlled in such a manner that ink drops are generated at a plurality of print positions along a line which extends perpendicularly to the major axis of the print head. The print control information for the ink drop print heads is generated by a photodetector group which extends over a major dimension of an original and is deflected along the other major dimension. The scanning data are stored on a magnetic disk. After one or several originals have been completely scanned, the scanning data are read out of the magnetic disk and reorganised in order to generate ink drop control signals for the ink drop print heads.
