Title: Wheel suspension system for motor vehicles and other vehicles
Inventor: KUMAGAI NAOTAKE
IPC: B60G17/052
Filed: 1984-02-02
Abstract: The invention relates to a wheel suspension system for motor vehicles and other vehicles in which the oscillations of the vehicle body occurring when running over ground irregularities are reduced by switching the suspension into the "hard" state by increasing the damping capacity of the shock absorber and the spring constant of the air suspension chambers in accordance with a signal which is provided by a level sensor for registering the compressed or expanded state of the suspension. The variation of the spring constant is achieved by means of a construction according to which an air suspension auxiliary chamber seated on an air suspension main chamber enclosing the piston rod and an air passage inside the piston rod are provided for the interconnection of the two chambers in the system, the connection and separation of the two chambers through the air passage being controlled by means of the piston rod and a driving pin extending into the piston rod.

Patent DE-3431683-A1 (DE)
Title: Hydraulic system
Inventor: KLOTZBUECHER WOLFGANG DIPL ING
IPC: F16H61/40
Filed: 1984-08-29
Abstract: The hydraulic system has a pump (10) with constant delivery volume which supplies pressure medium to at least two hydraulic motors (13, 21, 23) connected in parallel. A flow control valve (24 to 26) is connected upstream of each hydraulic motor. Each consumer line has a pressure tapping point (P1 to P3) via which the load pressures of the individual consumers are directed via shuttle valves (29 and 35) to a pressure-relief valve (18), this pressure together with the force of a spring acting on its closing member in the closing direction. During operation, the opening pressure of the pressure-relief valve (18) in each case corresponds to the maximum load pressure at a consumer plus the differential pressure between pump and consumer. The pump (10) is designed in such a way that its delivery volume is greater than the sum of the volumetric flows which can be set at the flow control valves. Depending on the type of loading, the excess volumetric flow is discharged in a controlled manner to the tank via the pressure-relief valve (16) or via the pressure valve (18). In this way, an energy-saving hydraulic system working without problem is obtained. <IMAGE>

Title: Arrangement for preventing the grinding wheel from colliding with the workpiece on grinding machines
Inventor: KELLER GERT
IPC: B24B49/00
Filed: 1985-02-25
Abstract: Arrangement for preventing collision on grinding machines, which arrangement possesses a control for the feed drive and a path-measuring system in the feed axis, using an emergency shutdown device, a tachometer generator and a speed control for the feed drive, in particular for plunge-cut grinding. The aim is to reduce the idle times of the grinding process by fully utilising the maximum possible feed rate, while ensuring the prevention of collision. For this purpose, the braking phase is to be monitored such that changes in the braking progression can be acted upon virtually without delay. This is achieved in that the desired speeds occurring in the pre-coincidence points of the feed axis are connected up as analog voltages at the first input of a comparator assigned to each pre-coincidence point. The second inputs of all the comparators are situated together at the outlet of the tachometer generator and, for each pre-coincidence point, an AND-element is provided which is connected, at the input end, to the associated comparator and to the appertaining pre-coincidence outlet of the control. The outlets of the AND-elements are connected, via a common OR-element, to the call-up inlet of the emergency shutdown device.

Title: Mast extension with integrated return spring and swivel pulleys on the mast for a sailboard
Inventor: ECKSTEIN KLAUS
IPC: B63B35/79
Filed: 1985-08-13
Abstract: Mast extension with pulley block running on the inside and having rotatably mounted pulleys and a return spring. Mast extensions of known type are produced in such a way that, due to the twist of every rigging on the market, this rigging often turns in on itself during release and thus twists together due to the narrowness of the tube in which up to 6 rope lengths often run, and the pulley block consequently ceases to function. Laborious dismantling of the entire unit is then inevitable. The object of the invention is therefore to provide the user with a mast extension which makes the twisting of the pulley block impossible. In the subject-matter according to the invention, this is achieved in that the pulleys located in the tube are provided with rotatable receptacles and in addition a return spring is fastened to the latter, the rotatable receptacle having the task of absorbing the twist of the rigging, and the return spring having the task of always keeping the rigging which runs on the inside slightly tensioned.
