Patent DE-3604438-A1 (DE)
Title: All-wheel steering system for motor vehicles
Inventor: WAXENBERGER ERICH DIPL ING
IPC: B62D7/15
Filed: 1986-02-13
Abstract: An all-wheel steering system for motor vehicles has a front-wheel steering device and a rear-wheel steering device, of which the latter can be actuated as a function of the actuation of the former by an actuating rod. The actuating rod is articulated, on the one hand, to a swivelling lever which swivels in the case of a front-wheel steer angle and, on the other hand, to an actuator of the rear-wheel steering device. Starting from the straight-ahead position of the wheels, on initial turning of the steering wheel the rear wheels are turned by way of swivelling lever, actuating rod and actuator, jointly with the front wheels in the same direction through a relatively small angle and on continuous turning of the steering wheel in the same direction are turned through a larger angle in the opposite direction to the front wheels. The steering movements of the rear wheels directed in the same direction and opposite direction can advantageously be brought about if the swivelling lever forms a crank which can be rotated by operating the steering wheel, the actuator forms a rocker and the actuating rod forms a connecting rod of a four-bar linkage. The four-bar linkage in particular offers the advantage of being able to vary the reversal point of steer angle in the same direction to steer angle in the opposite direction.

Patent DE-3641939-A1 (DE)
Title: Vehicle cleaning system
Inventor: FREIMUTH FRIEDRICH
IPC: B60S3/00
Filed: 1986-12-09
Abstract: In order to improve the preheating of the surfaces to be cleaned of public-service vehicles in the pass-through process, a more intensive heating of the surface is possible by virtue of keeping the heated medium for a longer time and by virtue of a rinsing technique. Both measures may be assisted by encapsulation/shielding adapted to the pass-through process. Because of the more intensive heating which is possible, the specified pass-through process does not require a long distance to be covered, and hence the preheating section of the cleaning system is kept short. In order to improve the cleaning action when cleaning road vehicles in the pass-through process, a cleaning device is formed from brushes which are arranged in parallel and may be arranged vertically or horizontally. The brushes are controlled by control elements which are operated directly or indirectly from the vehicle to be cleaned. The brush sets may be mounted in a frame on one side or on both sides. The arrangement and control of the cleaning brushes allows all brushes to follow the outline of the vehicles precisely, i.e. in the effective cleaning range of the brushes. As a result, a higher degree of cleaning is achieved and this makes a decisive contribution to the external appearance of the carrier's vehicles. In order to improve the removal of the rinsing water from cleaned public-service vehicles brushes are provided. The brushes can ... as rotating ... Original abstract incomplete.

Patent DE-3707463-A1 (DE)
Title: Paraglider
Inventor: DOLEZALEK FRIEDRICH K DIPL PHY
IPC: B64D17/02
Filed: 1987-03-08
Abstract: A paraglider which is formed from flexible materials, can be inflated by the incident flow and has a wing top and a wing bottom which are connected by means of structural elements such as material webs, strips, cables etc. which limit the separation, such that a wing shape (aerofoil shape) is produced in the inflated state. In the case of known paragliders, the actually existing profile deviates severely from that predetermined by the ribs (4), as a result of which the gliding ratio and the speed are reduced. The number of ribs cannot be increased indefinitely, since the weight and the packing volume would otherwise become excessive. According to the invention, all or only some of the separation-limiting structural elements are arranged over only a part of the profile depth, to be precise preferably in the nose region and in the rear third of the profile depth. In consequence, a good approximation to a profile which is uniform in the span direction is achieved at a low cost. The device is used for jumping out of aircraft, for hang-gliding after a running take off from a slope or for towed flight.

Filed: 1987-04-16
Abstract: A structural element for producing a construction (100) which is formed from a triangular strut (14) and two panels (10, 12), which are releasably connected to said strut and are parallel thereto, exhibits two cap-like head pieces (16, 17) for connecting each panel (10, 12) to the strut (14). The panels (10, 12) rest loosely, by means of a side border part (13), against the outside of the strut (14) and terminate essentially flush with said strut at both ends. Plugged onto each end of the strut (14) is a cap-like head piece (16, 17) which exhibits peripheral flange parts (23) which clamp the panel (10, 12) and the strut (14) together by engaging over them. In order to prevent displacement of the panels (10, 12) with respect to the head pieces (16, 17), the invention provides that one flange border part (26) of each head piece (16, 17) engages into a continuous transverse slot (20) which is formed in the borders, running transversely to the strut (14), of each panel (10, 12). A large number of differently configured constructions of all sizes can be erected by means of the structural elements according to the invention, simple mounting and demounting being possible. <IMAGE>

Title: Vacuum cleaner, in particular hand vacuum cleaner (upright vacuum cleaner)
Inventor: NAUTA WILHELM D DIPL ING
IPC: A47L9/12
Filed: 1987-08-21
Abstract: It is proposed, in a vacuum cleaner having a dust-collecting chamber in which a filter-supporting basket is arranged and is covered by an easily exchangeable, sheet-like filter material, to use as filter material a filter sheet which before insertion is substantially plane and upon insertion is gathered together at least in the edge regions and whose edge region is easily detachably fastened to the supporting basket by means of a clamping device. As a result, the object of increasing operating convenience is achieved. Since a widely available or easily obtainable filter material, such as a paper handkerchief or a kitchen towel, can be used, which moreover is inexpensive, the filter can be frequently changed and it is not necessary to procure a special replacement part. As clamping device, use is preferably made of a clamping ring which is displaceable substantially in the axial direction of the filter basket relative to the filter basket, clamps edge regions of the filter sheet against the supporting basket and, in order to lessen the danger of the filter sheet tearing, is preferably placed against the supporting basket from the open side thereof. The fastening of the filter sheet on the supporting basket is facilitated if the supporting basket can be separated from the rest of the appliance and the filter sheet can be turned down over the open edge of the supporting basket. <IMAGE>

Patent DE-3800678-A1 (DE)
Title: Shock absorber
Inventor: BOCK PETER JUERGEN DIPL ING
IPC: F16F9/53
Filed: 1988-01-13
Abstract: The invention relates to a shock absorber with a piston which is guided in a cylinder and has a coil through which particles contained in the hydraulic fluid and capable of being aligned magnetically and the viscosity of the fluid can be varied during the movements of the piston. During this process, the damping fluid flows through an annular gap between the coil wall and the inner wall of the cylinder, while, once aligned, the particles maintain their position unaltered. In contrast, the invention envisages the extension of the action to the viscosity of the damping fluid in the magnetic field of the coil. To this end, the coil is guided with turns which are spaced apart, leaving flow passages, with the result that the damping fluid passes through the flow passages of the coil. Alternating directions of flow, A.C. operation and permanent-magnetic particles in suspension in the damping fluid are used to ensure that the damping force is influenced for the entire period during which the damping fluid is passing through the piston formed by the coil.

Title: Circuit arrangement for controlling the rotational speed of a hydrostatic machine
Inventor: REINHARDT PETER
IPC: G05D13/30
Filed: 1988-01-14
Abstract: The invention aims at improving the control of the rotational speed of a hydrostatic machine, in which a limiting signal is formed as a function of the acceleration of the machine, which limiting signal is used for driving the controller of the rotational speed of the machine. The limiting of the rotational speed according to the invention is significant for the control behaviour in the case of disturbances occurring in the drive since, in particular in the case of a torque overshoot of the machine, for example in the event of load-shedding, an impermissibly high rotational speed of the drive is prevented.
