Patent EP-0325466-A3 (EP)
IPC: C09K8/54
Filed: 1989-01-19
Abstract: The present invention relates to the application of a synthetic hydrocarbon compound, a polyalphaolefin liquid, blended in various concentrations with chemical oil and water emulsifiers, thinners and oil and water surface tension reducers, the concentration of polyalphaolefin liquid to that of the remaining portion of the blend being no less than 5%; blending the polyalphaolefin liquid and the emulsifiers in a blending tank containing water base drilling mud; circulating the blend of polyalphaolefin liquid and emulsifier with the water base drilling mud down hole, so that the blend of polyalphaolefin liquid emulsifier and water base drilling mud lubricates the drill string or reduces the differential pressure between the wall of the borehole and the drill string so that the drill string is free to rotate and drilling may be undertaken with less drag or torque. In another application, the polyalphaolefin blended with the emulsifier serves as a spotting fluid in order to unstick drill pipe that has become stuck. In this method, the polyalphaolefin is blended with the emulsifiers; the polyalphaolefin emulsifier blend is introduced into the borehole as a "pill"; the pill is circulated downhole in the mud system through the annulus to the depth at which the pipe is stuck; the polyalphaolefin emulsifier blend acts on the differential forces between the wall mud cake and the pipe to reduce the differential pressure between the pipe and the formation, so that the pipe is freed and drilling is able to resume.

Title: Device for conditioning and dewatering sludges in a filter press
IPC: B01D37/03
Filed: 1990-07-05
Abstract: The device comprises a conditioning part fitted with a mixing vessel, which serves for intimate mixing of sludge and a conditioning agent, and a pump part, connected by lines to the mixing vessel and to a chamber filter press, for delivering the conditioned sludges from the mixing vessel to the chamber filter press and for subsequent pressing of the sludges in the chamber filter press. The pump part comprises at least two reciprocating pumps which are driven essentially in opposite directions and are connected to a common delivery line. The pump drives are also controlled in such a way that the delivery stroke of one pump always starts before the other pump has finished its delivery stroke. This results in an essentially constant pressure level downstream of the pumps, because the pressure stroke, initiated with an advance, of one pump in each case is effective before the other pump has reached the outer dead centre. <IMAGE>

Title: Material with radar absorbing properties and its use in methods of camouflage against radar investigation
IPC: C09D5/32

The particles are uniformly distributed in such a way that the direction of their minimum or maximum linear dimension is essentially perpendicular to the layer and this determines the layer thickness. The layer is on a substrate which is virtually completely reflective in the cm and mm electromagnetic wave range. 2.3 Camouflage against radar investigation. <IMAGE>

Title: Brake device for railway vehicles, especially a shoe brake for at least two sets of braked wheels
IPC: B61H13/26
Filed: 1990-11-26
Abstract: The largely automatic resetting of the brake linkage of brake devices, in particular of shoe brakes for railway vehicles, takes place usually by means of single-action or double-action linkage actuators at the start of the associated brake linkage chains. In the case of longer brake linkage chains, the resetting can no longer be compensated solely by the linkage actuator and the positions of the brake levers at the end of the chain can become so unfavourable that adequate functioning of the brake device is no longer ensured. So that additional manual resetting of the brake linkage can be largely dispensed with and the efficiency of the brake device improved, in a brake device of the generic type at least one further linkage actuator is arranged in series in the brake linkage chain behind a forward-mounted linkage actuator. The required resetting path for the linkage actuator which is respectively mounted downstream is determined by the control stop which is coupled relatively to the forward-mounted linkage actuator limit point. The control stop of the respectively forward-mounted linkage actuator is arranged so as to be longitudinally displaceable on the frame in relation to the linkage actuator and is connected to the linkage actuator which is arranged after it. <IMAGE>
