Patent DE-4039629-A1 (DE)
Inventor: OTTERBEIN STEFAN DR
IPC: B60G17/018
Filed: 1990-12-12
Abstract: A system is disclosed for generating signals for controlling or adjusting the chassis with controllable or adjustable movements of a private car or commercial vehicle. In order to minimize the movements of the car body, sensor signals of the suspension deflection quantities and/or speeds are repeatedly interconnected and influence each other by means of travels (Xarvl, Xarvr, Xarhl, Xarhr) that represent the driving state, such as the transverse and longitudinal accelerations (aq, al) and the speed of the car. The collective movements of the car body, in particular the proper motions of the car body (such as the swinging, pitching and/or rolling motions (Zb, alphab, betab) or vertical displacements (Xagvl, Xagvr, Xaghl, Xaghr) of the car body at the front and rear axles of the car body), are thus reconstructed. On the basis of these roper motions, the vertical movements of the car body at the engagement point of the suspension system on the car body are determined and compensated in a known manner by adjusting the suspension systems. The proper motions of the car body can thus be appropriately minimized by weighting.

Title: Sewing machine control - uses motor speed and needle position to regulate motor speed according to the situation and prevent slip
Inventor: WAKANA TAKAYUKI
IPC: H02P21/34
Filed: 1991-01-08
Abstract: The sewing machine control system establishes the rotary speed of the electro-motor and the needle position. The rotary transfer ratio is calculated from the needle position recognition signal and the output of the rotary speed meter. The start time of the computation is controlled, and the speed of the electro-motor is regulated according to the computed results. Pref. the computing start time is controlled to come into effect after a given time from the start of the electro-motor. The increase rate, by time, during an acceleration speed command to set the rotary transfer ratio and while measuring the rotary transfer ratio is less than after the end of the operation to determine the rotary transfer ratio, and this value is reduced to a given speed:time ratio. On the development of a fault, while establishing the rotary transfer ratio, the rotary ratio is less than before the fault developed and the motor speed is regulated by multiplying the sewing machinee speed with the rotary transfer ratio. After the situation has been assessed, a data value is applied to the computer outside the preset value range which is applicable to the measurement time period or a computing result to give a much lower motor speed. ADVANTAGE - The system stops the operation in the even of a breakage or other stoppage, prevents slip, and reduces working speeds for safety when a fault develops.

IPC: E21B33/128
Filed: 1991-04-24
Abstract: Pipe-plugging cartridge comprises a hermetically closed cartridge that, by a combination of explosives and internal design, undergoes permanent enlarging of its periphery. Ignited by a radio signal, an accurately-calculated explosion take place in the combustion chamber (2) and the pressure wave drives the plunger cone (4) into the segmented steel plug (6,6a) and expands it outwards, together with the steel casing, to seal the pipe.

The cylindrical casing (1) has wall thickness allowing the explosive force to act only on the plunger cone (4), which has sealing rings (5) and is held in place (before the explosion) by the distance piece (4a). The thread (7) holds the conical point (8) securely in the casing (1). In the explosion chamber (2), there is a radio-controlled igniter (3) for the carefully-calculated explosive charge. USE/ADVANTAGE - Pipes in difficult situations, e.g. in a borehole fire, and broken pressure pipes, including those carrying flammable or other matter in nuclear power-stations or elsewhere, can be quickly closed off from a safe distance (claimed). If necessary, camera equipment can be used instead of direct viewing of the work (claimed).
