Title: Improvements in or relating to multi-stage pumps
IPC: F04C11/00
Filed: 1954-07-02
Abstract: 812,812. Radial cylinder pumps. WOODCOCK, F. H. June 20, 1955 [July 2, 1954], No. 19386/54. Class 102(1). [Also in Group XXVI] A fluid pump has two stages, the first stage comprising a pump of the sliding vane type and the second stage comprising pistons mounted on the inner ends of the vanes reciprocating in radial cylindrical bores in the rotor. In the embodiment illustrated sliding vanes 30 co-operate with a track ring 29 which is the inner race of a needle roller bearing 28 and rotates with vanes 30 which are urged outwards by spring rings 65. Fluid enters suction spaces 35 from an inlet passage 34 and is discharged from pressure spaces 37, through an outlet port 38 and through a passage 39 into two inlet passages 42 in a stationary pintle member 40 which is a running fit in a bore 41 in the rotor shaft 19. The fluid then passes through an arcuate inlet port 46 to cylinders 33 when it is acted upon by pistons 32 and discharged through an arcuate port 47 into a passage 48 in the pintle communicating with a discharge connection 49. The capacity of the sliding vane first stage pump is greater than that of the second stage and accordingly a relief valve 50 is placed in a passage 51 leading from the outlet port 38 of the first stage pump to a low pressure discharge connection 52. A ring 26 containing the bearing 28 is pivoted in a bore 15 in the pump casing about a pin 61 to vary the eccentricity of the track 29 with respect to the rotor 12, the eccentricity being controlled by a discharge pressure actuated piston 56 and an adjustably spring loaded piston 59 so as to decrease the pump capacity on increasing discharge pressure.

Patent GB-413869-A (GB)
Title: Improvements in processes for making basic magnesium carbonate
IPC: C01F5/24
Filed: 1933-07-11
Abstract: Basic magnesium carbonate is obtained by adding carbon dioxide to an aqueous suspension of magnesium oxide or hydroxide containing ammonia in quantity substantially less than would be present if the ammonia and carbon dioxide were added as ammonium carbonate.  The quantity of ammonia used is about 1,5 to 10 per cent by weight of the magnesium oxide or hydroxide.  The suspension may contain 1 part magnesium oxide or hydroxide to 10--30 parts of water.  It is preferably carbonated with agitation in a closed vessel, and the influx of carbon dioxide may be continuous and at such a rate that a pressure of one fifth of an atmosphere above atmospheric is attained. Alternatively, the carbon dioxide may be passed into the vessel until the above pressure is reached and the influx then discontinued until atmospheric pressure is attained.  More carbon dioxide is then added, and so on.  Carbonation is continued in both modifications until the mixture begins to thicken.  After solidification, the mass is dried, preferably in a closed vessel for recovery of ammonia, and the dried mass may be cut into blocks or powdered. The apparent densities of the products of the continuous and intermittent carbonation processes are respectively 0,10--0,12 and 0,06--0,07.

Title: Improvements in or relating to electronic devices for selective operation of circuits
IPC: H03K17/54
Filed: 1951-08-27
Abstract: 709,649. Multi-stable state circuits. HEEMAF, N. V. Aug. 27, 1951 [Aug. 26, 1950], No. 20188/51. Class 40 (6) The Figure shows a circuit for selectively operating a given electronic relay in dependence upon the value of an incoming control voltage. Valves 1a, 1b, 1c are normally biased to cut-off at their control grids by the progressively increasing voltage drops at the taps of potentiometer 18. When a positive control voltage of a predetermined level is applied at line 15, valve 1a alone conducts and the electromagnetic device 2a is operated. If a positive control voltage of greater amplitude is subsequently applied at 15, valves 1a and 1b are initially rendered conductive but before device 2a operates valve 1a is cut-off at the second control grid by the voltage drop across resistor 6b caused by the screen-grid current flow in valve 1b so that device 2b alone is operated. If a positive control voltage of still greater amplitude is applied subsequently at 15 valves 1a, 1b and 1c initially conduct but before devices 2b and 2a operate valve 1b is cut-off at its suppressor grid by the voltage drop in resistor 6c due to screen-grid current flow in valve 1c and valve 1a is cut-off at its second control grid by the voltage drop across resistor 6b due to the screen grid current flow in valve 1b; thus device 2c alone is operated.

Layer 6 serves as an anti-reflection coating and prevents evaporation of (a) p+ layer during high temperature outgassing (e.g. 1200‹ C.). Its minimum optical thickness is preferably a quarter of the wavelength, or mean wavelength of the incident light, in the nitride and for infra red and Á = 2 is of thickness 0À11 Ám. Preferably the two major surfaces of the membrane are parallel and the same size, and a work function reducing material provided (e.g. caesium oxide). The impurity is preferably boron, typically negligible at depths greater than 0À1 to 0À2 Ám. Concentrations and thicknesses are given. Preferably the p+ layer is diffused from boron oxide vapour deposition or may be produced by ion implantation. The nitride may be vapour deposited and may be produced by passing silane gas and ammonia gas in an inert gas over the membrane at 800‹ C. and the p/c outgassed at 1200‹ C. prior to caesium oxide deposition. Membrane 1 with frame 2 may be formed by an etchant while rotating. Radial supports (3) (Fig. 2, not shown) increase mechanical strength.

Title: Projectile fuzes
IPC: F42C15/18
Filed: 1959-06-12
Abstract: 911,474. Ammunition fuzes. INDUSTRIALHOLDING-ESTABLISHMENT. June 12, 1959 [June 14, 1958], No. 20271/59. Class 9 (1). A projectile fuze operating on impact has a body 1 on which a cap 2 enclosing the percussion means is held by a split ring 3 housed within slots 4, 5 in the cap and body respectively so that the cap may be rotated relatively to the body. A screw 6 bearing on the ring 3 is tightened to lock the cap in any desired position, the periphery of the cap being quartered by markings indicating safety, instantaneous action, short delay and long delay respectively, when brought into register with a datum line 10 on the body 1. When set at safety the firing-pin 11, which is engaged by a spring-supported striker 12, is held by a bolt 14 secured in the locking position by a stud 17 projecting from a piston 18. The piston is thrust forward by a spring 19 and held by a ball 21, which bears against the inner surface of the cap 2, within which surface are three recesses 24, Fig. 3, corresponding to the other settings of the fuze. The appropriate recess 24 is brought into alignment with the ball 21, when the fuze is set. At the same time a barrel 33 rotates about a pivot 35, which slides in a radial slot 36, and thus brings the appropriate primer 34 into register with the pin 11. The barrel may, alternatively, be rotated by providing a groove in the barrel co-operating with a pin extending from the casing. When an unrotated projectile fitted with the fuze is launched, the piston 18 sets back due to inertia, forcing the ball 21 into the recess 24, withdrawing the stud 17 and becoming wedged on a member 42. The bolt 14 is then held only by a rod 52, which bears against an obturating plate 40 having a toothed segment 47 co-operating with clockwork 48 to prevent arming in the initial stage of the trajectory. As soon as acceleration ceases, the piston 18 and member 42 move forward together, withdrawing a pin 43 and so unlocking a rocking lever 44 forming part of the clockwork. The spring motor 46 then drives the clockwork, which rotates a barrel 26 until a detonator 30 housed therein is aligned with a flash passage 39 and the selected primer 34. When the quadrant 47 has rotated sufficiently for plate 40 to free the rod 52, the bolt 14 frees the pin 11 and the fuze is armed. The barrel 33 is slidable in its housing 23, so that if the projectile is arrested by impact with soft ground, the barrel moves towards the firing pin to initiate the primer. Such action may also be produced by deceleration. The toothed quadrant may be replaced by a rack driven by a spring in an unrotated projectile or by centrifugal force in rotated projectiles.
