Abstract: ABSTRACT OF THE DISCLOSURE          A friction welding apparatus for joining thermoplastic materials, such as a reinforcing plate to the inner surfaces of oppositely disposed legs of a generally U-shaped workpiece, includes flexible force applying means for applying a force in a direction normal to the direction of relative motion between the parts but in the plane of the mating surfaces for urging the legs of the U-channel into intimate contact with the edges of the reinforcing plate.  During a weld time interval the parts undergo relative linear reciprocating motion while being urged in intimate contact by the flexible force applying means which causes the mating surfaces to soften under the influence of friction.  After the weld interval, the parts are returned to their original position and are held in forced contact for a time sufficient for the mating surfaces to solidify.  Upon solidification the force ceases and the welded parts are removed from the apparatus.

Abstract: Abstract A turntable in a bottle-processing machine, more particularly a labelling machine, has a plurality of sensor-controlled rotating plates arranged in a circle, and a flat, stationary control-cam.  The cam is scanned as the turntable rotates by the rotating-plate sensors each sensor pivoting a rotating plate back and forth by means of a lever-arm guided trailingly in the control-cam.  A gearwheel connected to the lever-arm is arranged between and meshes with gearwheels of two adjacent rotating plates.  The two rotating plates controlled in rotation by the same gearwheel, are mounted, together with the gearwheel and its lever-arm, in a common cup-shaped housing-block. The turntable has sockets in which the housing-block may be secured, in a predetermined rotational position, by means of stops, catches, or the like.

Abstract: ABSTRACT:         In a printer, for example, an ink jet printer comprising a guide device for a record carrier, the record carrier is fed by means of a transport roller to an adjoining supporting surface along which a printing head is displaceable.  The supporting surface extends in a plane which segmentally intersects the path of the record carrier around the transport roller.  At the area of the supporting surface, a ruler presses against the record carrier without bringing it directly into contact with the supporting surface, so that the record carrier becomes S-shaped upon passage from its path around the transport roller to the supporting surface.

Abstract: ABSTRACT OF THE DISCLOSURE:         The hydraulic control-unit consists of a  housing, a control slide-valve displaceable in the bore of the housing, and a control-ring.  Axial displacement of the said control slide-valve makes it possible to connect together,  or to disconnect, various connecting lines, depending upon the position of the valve.  Located in an annular chamber, formed between a section of the housing-bore and the control-valve slide, is a control-ring arranged coaxially with the said valve and guided dis-placeably thereupon.  Valve-seats are spaced axially from each other, both in the housing-bore and on the control slide-valve. The said control-ring comprises inner mating surfaces and outer mating surfaces co-operating with the said valve-seats. Provided between the two valve-seats, in the control. slide-valve, in a duct running therein, the said duct being closed at one end or the other, depending upon the position of the said control-ring.  The latter is held, by the pressure of the flowing medium, in the appropriate closed position, but the change-over may be effected independently of the pressure, since no axial forces are applied to the said control slide valve by the following medium.

Abstract: ABSTRACT OF THE DISCLOSURE A pressure regulating valve for controlling pressure in high pressure hydraulic circuits includes a closure member with an integral control piston and a conical seating surface cooperable with a complementary surface on a seat member.  The valve closure member is biased in the closed position by an actuating mechanism including a pressure gas piston and cylinder arrangement utilizing a flexible diaphragm for sealing the actuator pressure chamber.  The effective cross-sectional area of the control piston is large enough to minimize the differences in cross-sectional areas on the closure member exposed to pressure fluid between the valve closed and valve open positions whereby a minimum variation between the valve opening pressure and the control pressure is experienced.  The increase in pressure in the actuator pressure chamber resulting from movement of the valve from the closed to open positions substantially offsets the change in effective face areas of the closure member to further minimize the difference between the valve opening pressure and the steady state regular pressure.
