Granted: 1989-04-20
Abstract: A penumatic valve which is suitable for use in controlling the operation of a penumatic drive system such as that used for raising and lowering the body of a dump truck. The valve is opened and closed by a slide member which is mounted in a cylinder formed in the valve housing. An air inlet passage opens into the cylinder and an air outlet passage and a vent passage open from said cylinder. A first flow control valve in the inlet passage which is operable to close to prevent and open to permit the passage of air from the inlet passage to the cylinder. A second flow control valve in the vent passage which is operable to close to prevent and open to permit the passage of air from said cylinder to the vent passage thereby to vent the outlet passage. The slide member is adapted to locate the first flow control valve in its closed position and the second flow control valve in its open position when in the first position and to locate the first flow control valve in its open position and the second flow control valve in its closed position when in the second position.

Title: Method and apparatus for producing foam
Inventor: BAUER ADOLF
IPC: B29K105/04
Filed: 1985-04-01
Granted: 1988-08-11
Abstract: Foam prods. are made from at least two reagents and a liq. foaming agent which is vapourised by the heat of reaction of the resin reagents. The reagents are mixed together by counterflow in a mixing chamber and an inert gas is added; and the mix is discharged into a mould cavity, if necessary via a flow-smoothing channel. The inert gas, foaming agent and/or other additives (e.g. colouring) are added at a point in the cylindrical wall of the mixing chamber which is in or close to the radial plane through the inlets for the reagents; the feed of the inert gas or foaming agent/other additives, etc. into the mixing chamber is controlled by a purging plunger. Specifically, the mixing chamber (2) is fixed at right angles to the flow-smoothing tube (4) and is emptied by a plunger (3), while the tube (4) has a similar plunger (5). The reagents e.g. isocyanate and polyol enter the chamber (2) at right angles to the figure (8a) at high pressure, while the plunger (3) is withdrawn. In the same plane as the two reagent inlets (one=8a, other is diametrically opposite) is the inlet (10) for the feed of (e.g.) compressed air whose pressure is somewhat higher than that in the chamber (2). The foaming agent is supplied (e.g. to one reagent before this enters the chamber (2). The inlet tube (10) is entered and purged by the end (12) of a plunger (13) which moves along to meter out the material added.

Abstract: Tools for the disassembly of a universal joint comprise two embodiments, a push-type tool and a pull-type tool. With respect to the push-type tool (Fig. 6), a cylinder/piston combination (18, 20) is mounted on a pushing or support assembly (80), and the cylinder/piston combination (18, 20) is operated to force the piston (20) against the support assembly (80), which in turn exerts a pushing force on the cross (intersection point of the yoke members) of the universal joint. At the same time, the cylinder (18), which is connected to the near end of a yoke member of the universal joint, exerts a pulling force on the universal joint, thereby forcing a journal bearing out of the yoke member. In the pull-type tool (Fig. 3), a cylinder/piston combination (18, 20) interposed between a pulling assembly (12, 14, 16) and a pushing assembly (28, 30) operates to cause the exertion of pulling and pushing forces on the universal joint, so that a journal bearing is forced out of the universal joint.

Abstract: The press tools (5,5a), in their relative movement, press a print-forming medium (10) through the stencil and on to the material to be printed. A centrally orientated plane applied to the press tools forms an obtuse angle between the stencil and the material, w.r.t. the movement of the press tools. With the two press tools arranged one beside the other, the centrally orientated plane forms a reciprocal angle less than 120 deg. and greater than 60 deg. Thus, the one press tool works in conjunction with the stencil for printing during a first movement, and the second tool works with the stencil with a movement in the opposite direction.

Abstract: An electric contact device for an electrical connection of electroconductive connectors comprises a row of interconnected contact elements which are joined together by at least one continuous band-shaped or wire-shaped spring element. Each contact element is provided with at least one opening through which the spring element extends. The opening provides for fixing of the contact element which, in an unstressed condition, extends at an angle maximum 45 DEG relative to the plane of the spring element. Under the contact pressure, the spring element is deformed and takes a wave form, thus, producing a resilient force. This permits to assemble the device with larger tolerances for spacing between the contact elements. Preferably, the edges of the contact elements have a high electric conductivity.

Abstract: The inefficiency of the nitrogen stripping section of a high purity oxygen-producing air distillation plant is reduced. This allows increased recovery of byproduct argon and in some cases increased recovery of refrigeration work also. The improvement is obtained by evaporating kettle liquid with condensing argon rectifier vapor in two sequential stages, to yield vapor streams respectively having more and less O2 content than the kettle liquid, and separately feeding them to the N2 removal column. The improvement is applicable to both dual and triple pressure processes. Referring to FIG. 1, kettle liquid is supplied via valve 11 to the top of contactor 18, and overhead reflux condenser 13 of argon rectifier 14 reboils the bottom of contactor 18. Vapor streams of differing O2 composition are withdrawn from above and below 18.
