Title: Improvements in seals and bearings for shafts
Inventor: BILBE WILLIAM GEORGE
IPC: F16L5/06
Filed: 1967-11-06
Abstract: 1,249,113. Integral bearing and seal. RICHARD KLINGER Ltd. 23 Oct., 1968 [6 Nov., 1967], No. 50439/67. Headings F2A and F2B. A shaft 2 is journalled in the wall 4 of a vessel or container under fluid pressure by means of an annular bush 6, made, e.g. of PTFE, which also serves as a seal to prevent loss of fluid from the vessel. One-third of the bush at the end which is adjacent the inside of the vessel, is formed to taper towards the end in the absence of the shaft so that when the shaft is positioned in the bush an interference fit results between the bush and the shaft. The remaining twothirds of the bush constitutes the bearing when the shaft is in position. A series of circumferential grooves 10 may be formed in the outer surface of the annular member, to further seal the vessel. Radial flanges 8 may be provided at each end of the bush to locate it in the wall.

Title: Pumping systems incorporating fluidic flow control device
IPC: F15C1/00
Filed: 1973-11-02
Abstract: 1480484 Liquid piston pumps UNITED KINGDOM ATOMIC ENERGY AUTHORITY 28 Oct 1974 [2 Nov 1973] 50915/73 Heading F1A A pumping system incorporates a fluidic device having two generally aligned and axially spaced members 1, 2 having tapered passages arranged to provide a convergent/divergent flow-path, and a tank 8 for receiving an alternating gas-pressure. In use with the device immersed in a body of liquid, the high-pressure pulses supplied to the tank 8 force liquid therefrom forwardly through the member 1, across gap 5 into member 2 and thence through outlet pipe 9, whereas the low-pressure pulses cause reversal of the liquid flow and consequent entrainment of liquid from the liquid body via the gap 5 to refill the tank 8. Thus the nett pumped delivery is the liquid ingress during reverse flow plus any liquid ingress during forward flow. The intermittent discharge through the pipe 9 may be smoothed by the provision of an accumulator 13. The latter may be connected to a gaspressure source, as shown in broken lines. In Fig. 8 (not shown) two fluidic devices and associated tanks (8) are connected to a common discharge pipe (9) to supply the pipe alternately and thereby provide a substantially continuous flow therethrough. The tank 8 may be provided with liquid-level detectors 12 to control the alternating gas-pressure supply.

A speed selector switch 13 is associated with resistors 19, 20, which are connectable across the output terminals 51, 53. When switch-arm 15 engages contact 17, resistors 23, 21 are shunted across resistors 12, 2, respectively to compensate for supply voltage and torque variations. Resistors 22, 24 are similarly associated with the contact 18.

Title: Method for forming composite articles

Abstract: 1356838 Making composites; turbine blades; welding by pressure UNITED AIRCRAFT CORP 17 Nov 1971 [28 Dec 1970] 53359/71 Headings B3A and B3R A method of forming a composite article comprises providing an alloy in a temporary superplastic state, providing a supporting material compatible with and more resistant to deformation than the alloy in its superplastic state, sandwiching the supporting material in between two sheets of the alloy, pressing the alloy around the material while maintaining its superplastic state, and diffusion bonding opposing faces of the alloy sheets together. Such temporary superplasticity results from particular processing of the alloy to put it in a condition which displays superplastic behaviour and yet such behaviour may be eliminated by appropriate heat treatment. The article may accordingly be heat treated to eliminate the temporary superplasticity of the matrix alloy. In a particular embodiment samples of a titanium alloy containing 6 weight per cent Al, 4 weight per cent Mo are rolled at 927 C. to give between 99- 400% elongation in tension. Two sheets of the alloy are positioned on opposite sides of a plurality of aligned stainless steel wires, Fig. 1, and the composite, Figs. 2, 3 (not shown), is formed by pressing under vacuum or in an inert gas at 927 C. The stainless steel wires can then be selectively dissolved in warm, 50% concentrated HNO 3  to form passages within the composite. The articles formed may comprise filamentstrengthened blades and vanes, and hardware with internal cooling passages for use in turbines.
