Title: Hospital bed with adjustable back rest
IPC: A61G7/002
Filed: 1988-05-20
Abstract: A hospital bed with an adjustable back rest according to patent ... (Patent Application P 3812262.6) has a frame carried by a chassis. The back rest comprises a support and a bearing part and can be rotated about a horizontal axle fixed on the frame.

In order to be able to simplify the structure of the hospital bed and hence to produce it in an inexpensive manner, it is provided, according to the invention, that the gear comprise a compression spring (20) and a cable pull (21), the compression spring (20) being connected to the support, on the one hand, and to the axle (4), on the other hand. The cable pull (21) is fixed to the support (6) and the frame and guided back via a deflection roller (22) arranged in front of a guide rod (23). The guide rod (23) is directed against the support surface and connected to the axle (4). <IMAGE>

Title: Method and driving device for influencing the position of hot rolling band
Inventor: KUPKA JOSEF
IPC: B21C47/34
Filed: 1988-08-20
Abstract: The invention relates to a method and driving device for influencing the position of rolling band which is fed to a winder, the driving device being provided with a first speed-regulated roll mounted in the standard and with a second speed-regulated roll mounted offset relative to the first roll in such a way that the roll axes are located in two vertical planes spaced horizontally from one another, the rolls being adjustable to nip clearances corresponding to different band thicknesses and, in the case of one of these, the two bearing housings being supported removably. As a result of deviations in the position of the band edge at the exit from the driving device, known methods and driving devices of this type lead to uneven end faces of the wound coils which, according to the invention, are avoided in that, in the case of a domed design of one of the rolls, forces are generated transversely to the run-through direction of the rolling band, with the positive connection in the driving nip being maintained, as a result of a staggering of the roll axes which is regulated according to the position of the band edge. An inadmissible deviation in the position of the band edge can be compensated by means of these forces, so that the coils can be wound with even end faces.

Title: Method for evaporating liquid natural gas
Inventor: SCHMIDT HANS DR ING
IPC: F01K25/10
Filed: 1988-10-22
Abstract: In a method for evaporating liquid natural gas with recovery of energy and with separate fluid circuits, natural gas which has been heated to ambient temperature is used itself for a first fluid circuit, which natural gas experiences a drop in pressure which supplies energy, condenses to form natural gas to be heated up and is fed back to the stream of liquid natural gas. In a second, enclosed fluid circuit which is operated with single-stage pressure reduction, hydrocarbon mixtures, propane or ammonia are used. It is easy to store the latter under pressure at a normal temperature. A third fluid circuit which operates with ethane as the circuit fluid can be added to the two first fluid circuits.

Patent DE-3841044-A1 (DE)
Inventor: SCHNITZHOFER NIKOLAUS ING
IPC: B61B13/04
Filed: 1988-12-06
Abstract: On monorails, the circumferential force has to be transferred from the driven roller onto the profile rail. It is particularly great during acceleration, braking and the overcoming of gradients, and at the high levels of acceleration and retardation as well as in the overcoming of gradients required in modern installations, would result in spinning of the roller. To solve this problem, it is proposed that the cross-sectionally horizontal running surfaces (11) of the profile rail (1) which interact with the driven roller (7) of the traction means (5) have a metal coating (15) applied by impact extrusion. <IMAGE>

Filed: 1989-08-04
Abstract: A regulating or control system for motor vehicles comprises n identical control units (A1BC-) each of which can be triggered, under a given address x, via a control line (L). The control units are switched on in succession so that all commands are sent directly to the first control unit (A), and each subsequent control unit receives its control command from the preceding control unit. If the ath control unit is triggered (a = 2 to n), the command initially receives the auxiliary address y = x + (a - 1). Each control unit is so designed that, if it receives an auxiliary address y = x + (a - 1) > x, it converts this address to y = x + (a - 2) and relays this with the control command.
