Patent GB-1022375-A (GB)
Abstract: 1,022,375. Valves. CONTIGEA S.A. June 18, 1964 [June 21, 1963], No. 25170/64. Heading F2V. A gas safety valve comprises a main valve closure 9, Fig. 6, which is opened by a push-button 22 and held open by an electromagnet 4 the current to which is controlled by a thermocouple. The pushbutton 22 has a rod 22a on which is mounted an auxiliary valve closure 26. The auxiliary valve is also opened on opening the main valve and may be held open on release of the push-button by a spring-loaded peg 24 engaging a shoulder 23 of the button. When the auxiliary valve is held by the peg, full flow of gas takes place through the valve and when the auxiliary valve is closed, flow takes place through a restricted passage 17 in the body or through a restricted passage in the auxiliary valve. The peg 24 may be replaced by a loose ball actuated by a cam surface of a spring-loaded button, or the ball may itself be spring-loaded. In a modification, a second valve closure 51, Fig. 19, controls the throttled passage 17a and this valve is opened on opening the main valve 9 by a lever 45 pivoted at 52 and held by pins 48, 39a. The lever 45 co-operates with a spring 53 so that the auxiliary valves may be held in any position to control the flow of gas through the valve, the valves being closed by pushing the button 50. The valve member 40 is mounted to slide on the push-button stem so that when the valve 40 is closed, flow may take place through the throttle 17a until the valve 51 is fully closed.

Abstract: 1,231,309. Bearings. GENERAL MOTORS CORP. 21 Aug., 1969 [3 Sept., 1968], No. 41673/69. Heading F2A. A rolling bearing 10 is lubricated by having the inner race formed of at least two coaxial members 18, and 20 which abut one another, the abutting surfaces being shaped to form an annular oil pocket 23 and an annular slit 25 which connects the pocket to the inner raceway there being provided at least one annular recess 27 so that in use oil is supplied from the recess via the pocket and the slit and discharged into the inner raceway. The members of the inner race may be provided with integral flanges 22 which define radial passages extending from the recess to the pocket. Oil is fed to the recess 27 via ports 28 which open into the interior 30 of the hollow shaft 11. Oil flows or is pumped along the shaft and accumulates in the pocket 23. On rotation of the shaft oil is forced outwardly by centrifugal action through the slits. The slits are such as to restrict the flow of oil so that it is forced out around the complete periphery of the slit. In an embodiment suitable for a roller bearing (Fig. 2, not shown) the inner race is made up of three members (41 and 42) one of which provides the raceway and the other two serve as axial abutments for the rollers. Two annular slits are provided, one at each end of the rollers. In a further embodiment (Fig. 4, not shown) passages are prvoided so as to lubricate the surfaces of the inner race and the separator (60) of the rolling bodies.

[Also in Division H1] A beryllium sheet less than 100 microns thick suitable for use as an X-ray window is rendered gas-tight by sputtering e. g. beryllium or beryllium oxide on it. The sheet 15 is opposite an electrode 5 to which a beryllium or beryllium oxide plate 6 is fastened. A magnetic field is provided by a coil 14 and a generator 8 provides a voltage of up to 4KV at a frequency of 20 MHz. Argon may be supplied at 5 x 10<SP>-3</SP> mm. If the coating is to be of beryllium metal, a capacitor is connected between the electrode 5 and the power supply 8 to cause the process to be preformed in the correct sense. It is alternatively possible to sputter beryllium in an oxygen atmosphere to produce a coating of beryllium oxide. The coating may be applied before or after the sheet is cut into window plates, or after a window plate has been mounted in a frame, or after a window has been arranged in an X-ray tube when it may no longer be flat.

Abstract: 1,232,309. Multiple-effect distillation apparatus; desalination of water. GENERAL ELECTRIC CO. 1 Oct., 1968 [5 Oct., 1967], No. 46436/68. Heading B1B. Saline water is desalinated in a multipleeffect distillation apparatus wherein the effects are disposed one above another, the first effect 4 being uppermost, each effect comprising a header 20, a vapour chest through which vertical double fluted heat-exchange tubes 24 extend, a liquid/vapour separator 22, and a heat-exchanger 40. The vapour chest 8 of the first effect is supplied with steam through connection 18, and the steam-condensate is returned to the steam-generator through line 16. The saline water is pumped up through heatexchangers 40 and lines 36 to the topmost header 20, filling all the other headers 20 in the process via lines 34. The saline water is sprayed from the headers 20 into the interior of the tubes 24 of each effect, so that the feed is supplied to the effects in parallel. A mixture of steam and brine emerges from the lower ends of each set of tubes 24 into the corresponding separator 22. The separated brine flows through line 26 into the separator of the next lower effect; and the steam flows through line 28 into the vapour chest of the next lower effect or, in the case of the last (i.e. lowermost) effect, to a condenser. The distillate formed in each vapour chest (except the first) drains through line 29 and line 28 into the vapour chest of the next lower effect. Desalinated water is withdrawn from the bottom of the apparatus through manifold 60. Brine is discharged from sump 64. Each brine drainline 26 is associated with a float valve for maintaining the required pressure differential between the effects.
