Abstract: An electrical circuit module in which structural elements of the circuit module are foamed or cast over with synthetic resin. At least one component is located in the interior of the resin and has an actuating shaft allowing adjustment of the component. An extension shaft that is rotationally symmetrical and has a driver is coupled to the actuating shaft. The extension shaft has a rotation-symmetrical bead and is embedded in the synthetic resin in a positive-fitting manner. The extension shaft also has an adjustment and protruding to the outside of the resin, and a surface which forms a separation layer toward the resin.

Abstract: A lubrication monitoring device for heavy duty diesel engines includes a plurality of measuring receivers connected at one level to driving spaces of the engine. Each receiver is assembled of a socket part secured to the wall of the engine and enclosing a lower and upper padding of resilient material pressed together by a pressure plate fastened to the top of the socket. Opposite lateral walls of the socket are formed with cutouts for receiving a ribbon cable which is integral with lateral elongated channels connected respectively to an underpressure and overpressure pump. The upper padding is provided with a connector block carrying a plurality of fork shaped contacts and with two hollow connection pieces which upon compression of the upper padding penetrate the elastic material around the elongated channels while the fork shaped contacts penetrate the insulation of the cable wires.

Abstract: An assembly for mechanically connecting an electrical cable to the housing of an electrical device comprises a cable jacket with an annular groove filled with a resinous substance such as polyurethane, the resin forming a prism fitted to an aperture in the device housing. The surface defining the groove is roughened and provided with a multiplicity of teeth.

Abstract: In a method and a device for controlling a lubrication film between a bearing surface and a shaft surface of the bearing assembly an electric circuit is provided, interconnected between the shaft and the housing of the bearing, in which a thermoelectric voltage is produced by friction heat which is generated at a contact between the shaft and the bearing when a break in the lubrication film occurs, and which termoelectric voltage is used as a voltage source of the electric circuit.
