Patent DE-3431404-A1 (DE)
Title: Vertically adjustable aerodynamic front fairing for motor cycles
Inventor: PRIEBE ROLAND
IPC: B62J17/00
Filed: 1984-08-27
Abstract: The vertically adjustable aerodynamic front fairing is to be a flexible, aerodynamic aid for motor cycles. This is achieved in that the fairing as a whole, or its lower part which is provided with a front spoiler, is lowered at relatively high speeds in order to improve the aerodynamic properties and are raised at low speeds in order to increase the ground clearance. A plurality of toothed vertical strips which are guided on a front frame extension arm and are connected via toothed wheels to one or more electric motors are attached on the inside of the fairing. As a result of activating the electric motor, and the associated rotation of the toothed wheels, the toothed strips, and thus the fairing, are moved. This process is controlled either automatically by an electronic control as a function of the travel speed or by the rider via a switch.

Title: Bell-type furnace and a method for heat-treating material to be treated
Inventor: POETKE WOLFGANG DR ING
IPC: C21D9/673
Filed: 1984-12-03
Abstract: In a bell-type furnace (1) for the soft-annealing of sheet-metal coils (6a, 6b, 6c) arranged one above the other in layers with a protective bell (3) placed over the sheet-metal coils and delimiting a treatment chamber (30), with a heating bell (2) surrounding the protective bell with a clearance, and with at least one burner (4) arranged near to the bottom of the heating bell (2), opening into the annular space (20) between the two bells (2, 3) and intended for the production of the annealing heat, to avoid overheating of individual coils (6a, 6b) at excess heating temperatures at least that section of the treatment chamber (30) which accommodates the bottom coil (6a) is surrounded by at least one layer (11, 12) of thermally insulating material. To shorten the process time for the soft-annealing of the sheet-metal coils (6a, 6b, 6c), the protective-gas atmosphere is heated with the aid of this bell-type furnace (1) to a limiting value about 40 DEG C above the annealing temperature. When this limiting value is reached, the heat output of the burner (4), of which there is at least one, is reduced in order to introduce the annealing phase. <IMAGE>

Title: Earthing-strip clamp having a universal connecting terminal
Inventor: ISSEL GERD
IPC: H01R4/38
Filed: 1985-01-23
Abstract: An earthing-strip clamp having a universal connecting terminal and having a clamping body to which the one end of the clamping strip is fixed, and having a pressure piece which is guided on the clamping body such that it can be displaced, acts on the free end of the clamping strip (which is inserted into the clamping body through an insertion opening) and fixes it in the clamping body, under the influence of a clamping screw. The centre part of the pressure piece is in this case designed like a hollow profile and is chamfered on its surface which interacts directly with the clamping strip. The wall of the centre part of the pressure piece facing the clamping screw has a recess in which the front, free end of the clamping screw engages in a positively-locking manner. As a result of this positively-locking mutual engagement, when the clamping screw is tightened, it is prevented from sliding off on the clamping strip.

Title: Tilting sliding roof for motor vehicles
Inventor: BAUHOF KARL
IPC: B60J7/05
Filed: 1985-02-11
Abstract: In a tilting sliding roof for motor vehicles whose rigid sliding roof cover is supported in a vertically adjustable fashion at the front end on sliding shoes so as to be capable of swivelling about an axis directed transversely with respect to the direction of travel, and at the rear end via extendable lifting levers, and which, during the displacement of the sliding shoes which bear the lifting levers, can be either lifted out of its closed position into a ventilation position or lowered out of its closed position into a sliding position, a considerable reduction of the necessary installation height is achieved in that the sliding shoes which support the lifting levers against the guide rails are themselves constructed as control links and the lifting levers are supported via in each case at least one pin in at least one slot-shaped guide track of the control links. Furthermore, the structure of the sliding roof is simplified overall in that the control links are of integral construction with the front-end swivel bearing of the sliding roof cover and, if appropriate, a transversely directed rain channel which is arranged at the rear end. <IMAGE>

Title: Apparatus for heightening concrete liquid-manure silos
Inventor: BATZDORFER ALFRED
IPC: E04H7/04
Filed: 1985-03-04
Abstract: In order to heighten said silos, sheet-steel elements are fastened by means of screws on the concrete-wall coping in which threaded sleeves are provided. Commercially available sealing means are used in order to seal the sheet-metal elements on the concrete-wall coping. In order to obtain a large sealing surface, the sheet-metal elements are bent off at a point corresponding to the width of the concrete wall. Laterally, there is a sufficient overlap for the screwing and sealing. If the statics are not sufficient for heightening the silos, a clamping ring is fitted. For this purpose, the sheet-metal elements are equipped with clamping-ring holders. In order to stabilise the heightening of the silos, the sheet-metal elements are bent off at the upper side. The abovementioned apparatus permits concrete silos to be heightened to a sufficient extent.

Title: Automatically sealing rotary valve for four-stroke piston engines
Inventor: CHRIST KARL DIPL ING
IPC: F01L7/02
Filed: 1985-08-01
Abstract: For some time internal combustion engines have been implicated in environmental pollution and especially in damage to forests. The catalytic converter is not an adequate solution; nor is limiting traffic speeds. The fitting of 4 to 5 valves per cylinder and the use of turbochargers offer no solutions to the problems either. Engines must be created which, utilising the technical advances in the relevant fields, enable all difficult problems to be identified and overcome. Few changes can be made to the basic design of an engine. The design of the cylinder head and the control elements fitted there are of crucial importance to the power output, consumption, inherent energy losses and exhaust gases. In the invention these elements - camshafts, rocker arms, springs, retaining means and disc valves with seats and bushings - are replaced by a ROTARY VALVE of extremely simple construction. Basically there is nothing new about a rotary valve. For more than 50 years, however, no design has met with any success. The difficulties lay in the thermal expansion which prevented absolute sealing off of the compression pressure and often led to valve fracture due to pitting and imbalance. These obstacles and disadvantages are overcome by a rotary valve, the sealing and constant sliding properties of which are obtained by an intermediate element which, easily movable axially, adjusts the contact pressure on the rotary cone to the requirements ...

Patent DE-3531987-A1 (DE)
Title: Fluid clutch which can be emptied and filled rapidly
Inventor: BRYCHTA PETER DIPL ING
IPC: F16D33/16
Filed: 1985-09-07
Abstract: It is advantageous if fluid clutches of machines used in underground mining and tunnel construction are completely emptied and then refilled after a thermal response. To allow rapid emptying, a screwed drain plug and, offset by 180 DEG , an adaptor for a compressed-air connection must be arranged at the lowest point of the working space, the compressed-air connection simultaneously being capable of being connected to a liquid-metering device. The fluid clutch is furthermore designed in such a way, particularly in the region of the retardation chamber, that, when stationary, the filling medium runs reliably to the screwed drain plug arranged at the lowest point. To measure and monitor the filling level, an electronic gauge rod is inserted into the retardation chamber or a pressure sensor is arranged in the region of the screwed drain plug, via which rod or sensor all the significant values are detected and fed to an evaluation unit. <IMAGE>

Title: Safety circuit for a power press
Inventor: TRAEDER KURT
IPC: F16P3/20
Filed: 1985-10-19
Abstract: The aim and object of the invention are to improve a safety circuit for power presses further such that optimum, cyclic self monitoring of the two cam-controlled limit switches takes place as a result of the evaluation, by means of circuitry, of the actual sequence of its control signals with the predetermined required sequence, and its evaluation in the switching-on circuits of the coupling switching apparatuses (switchgear) in the safety sense, while minimising the cost and increasing the reliability. This is achieved according to the invention in that the limit switch S2 has connected downstream of it a capacitor charging and discharging circuit 21 (which is controllable inversely by the limit switch S3 by means of its directly associated transfer relay K4) having a common pulse relay K1 and two further exciters 3, 6 (which can be switched on by said relay) and self-latching circuits 4, 5, 7 for a coupling self-latching switching-on relay K3 and a handover and follow-up monitoring relay K2, a normally-open contact K3/3 in the self-latching circuit 13 of the coupling switching apparatuses K6, K7 of the operator-independent parts 20 - 22 of the starting switching-on circuit 12, and a further normally-open contact K2/5 in the self-latching circuit 13 located in series with the normally-open contact K3/3 are arranged such that they can be short-circuited to the operator-dependent parts 1 to 22 of the starting switching-on circuit 12, and the above circuits are designed such that they can be switched off as a function of the operating mode by an operating mode selector switch. <IMAGE>
