Title: A process for producing germanium monoxide
IPC: C01G17/02
Filed: 1953-12-22
Abstract: Germanium monoxide is recovered from a non-volatile material containing germanium dioxide by heating the material at 900 to 1100 DEG C. in a flow of gas-mixture comprising a reducing gas and an inert gas, at a pressure of 10 to 40 mm. Hg below atmospheric, and cooling the resultant gas to deposit the monoxide.  According to Examples, (1) a ferric oxide powder containing 1 per cent of germanium dioxide was placed in a fused silica boat in a fused silica tube surrounded by an electric furnace.  After displacing the air in the tube with coal gas the tube was heated to 900 DEG C. and the pressure within the tube reduced to 14 mm. Hg below atmospheric. Heating was continued for 2 hours at this pressure in a flow of coal gas whereby germanium monoxide was volatilized and deposited on the cooler parts of the reaction tube; the reaction tube may be provided with a cooled and detachable tube to collect the germanium monoxide deposit.  Germanium monoxide deposit may be converted to germanium tetrachloride by heating to 400 DEG C. while passing chlorine through the tube.  A further example relates to reduction by a mixture of nitrogen and hydrogen.

Title: Improvements in actuating mechanism for fire extinguishers and other fluid containers
IPC: A62C35/60
Filed: 1934-12-12
Abstract: 447,621. Fire-extinguishing; releasing pressure-fluids. GRAVINER MANUFACTURING CO., Ltd., First Avenue House, High Holborn, London, and SALMOND, H. M., Briarwood, Fareham, Hampshire. Dec. 12, 1934, Nos. 35692 and 36035. [Class 47 (ii)] [See also Group XXVIII] Relates to means for actuating fire-extinguishers or other pressure-fluid containers, and consists in providing a spring-biassed cam adapted, when a locking linkage is released by shock or heatsensitive or manual devices, to drive in a selfretracting seal-piercing element. As shown, an extinguisher a of the pressure type is held in a bracket c with its plunger b above a rotatable spindle 3 carrying a cam 2. Levers 4 carried by the spindle are so connected to springs 6 that the tension of the latter acts mainly through the spindle 3 when the levers 4 are in set position. The levers are locked in this position by brackets 16 on a lever 14 which is pivoted at 15 and is locked by the lower end of a lever 13, the upper end of which engages a lever 12 which has, at its outer end, a pin engaging a pendulum 8. The latter is freely pivoted at 9 and is damped by a spring 17 fixed to an adjustable support 18. When the pendulum is displaced by a shock, the lever system 12, 13, 14 is released, and the springs 6 rotate the levers 4 and cam 2. These are so arranged that the cam exerts a maximum thrust on the plunger at the moment the latter is piercing the seal of the extinguisher. When the stroke of the levers 4 is completed, the cam has turned through an angle of 180‹, and the plunger b is free to be retracted by its spring. The pendulum may have a spherical depression engaged by the pin on the lever 12, or a conical depression to avoid inadvertent release of the lever due to vibration. In the latter case, the levers 12, 13 interengage through curved surfaces, and a spring 17a is provided for moving the lever 12 positively when it is released from the pendulum. For thermal and manual actuation, a spring-biassed lever 23 provided with a pin 26 adapted to displace the pendulum is connected to flexible cables leading to a hand knob and to heat-sensitive devices. The latter consist of thimbles soldered together and surrounded by inflammable material. The locking linkage 4, 16, 14, 13, 12 is so arranged that it can be reset automatically by rotating the spindle 3 to tension the springs 6. In a modification, the levers 12, 13 are dispensed with, the lever 14 having pins to engage the levers 4 and a stud seating in a recess in the pendulum. The lever 14 is biassed by a spring and is arranged, when released, to strike a blow on the levers 4 to move them initially past a dead-centre position. The pendulum is pivoted by a crank arrangement on the lever 23, so that movement of the latter, on hand or thermal actuation, lifts the pendulum to release the lever 14. The cam 2 is so shaped that the thrust applied thereby to the plunger b is proportional to the combined force applied by the springs 6 and the leverage of the levers 4.

Patent GB-818069-A (GB)
Title: Improvements to infra-red sensitive luminescent materials
IPC: C09K11/56
Filed: 1955-12-13
Abstract: In the production of an infra-red phosphor consisting of strontium sulphide, activators (Pb, Cs, Sm) and lithium fluoride as an auxiliary flux (see Group XL (a)), the strontium sulphide is obtained from a highly purified stronium nitrate (see below) by reaction with sulphuric acid and further reduction by ammonia or hydrogen at 1000 DEG  C.  The lithium fluoride is prepared by passing ammonia through distilled hydrofluoric acid until neutralization and reacting the ammonium fluoride so produced with lithium sulphate purified in the same manner as strontium nitrate below. The strontium nitrate is purified from heavy metal insoluble material by successive contacting of an aqueous solution thereof with a solution of oxyquinoline in chloroform or carbon tetrachloride followed by successive contacting of the strontium nitrate solution with a solution of diphenylthiocarbazone in the same solvents.  The strontium nitrate is thereafter crystallized. Alternatively the strontium nitrate solution may be adjusted to a pH 4 by adding ammonia or acetic acid and a solution of oxyquinoline in chloroform added.  After successive washings at this pH a second series of operations is performed at a pH=7 and then a similar washing procedure is performed with a solution of diphenylthiocarbazone in carbon tetrachloride pH's of 4, 7 and 10 successively.  The strontium nitrate so purified is treated with twice distilled sulphuric acid and the strontium sulphate precipitate is washed with distilled ethyl alcohol, vacuum dried and reduced in an alumina crucible at 1000 DEG  C. with ammonia or hydrogen.  Specifications 659,455, 650,458 and 650,459, [all in Group XL (a)], are referred to.

Title: Liquid fuel pumping apparatus
IPC: F02D1/02
Filed: 1973-07-28
Abstract: 1466245 Fuel injection pumps CAV Ltd 15 July 1974 [28 July 1973] 36055/73 Heading F1A In fuel injection pumping apparatus wherein a rotary valve 23, 24 connects one end of a bore containing a shuttle 19 alternately to the outlet 27 of a feedpump 25 and a drain, the other end of the bore being alternately connected by a rotary valve 20, 22 to the pumping chamber 11 of a fuel injection pump 12, 13 and, via a throttle valve 54, 55, to a source of pressurized fuel; the latter is maintained at a pressure lower than at the outlet 27 by a device 64. The throttle valve comprises a fixed sleeve 40 in which slides a rod member 41 acted on at one end by centrifugal governor weights 43 and at the other end by a valve-member 48 loaded by a spring 49. The force of the spring 49 is adjustable by an operator controlled member 51. The device 64, Fig. 2, comprises a valve element 69 slidable in a bore 65, the bore having an enlarged end in which is slidably disposed a piston 67 acted on by opposed springs 73, 74. Fuel from the feedpump is received in a circumferential groove 72 and passes therefrom through ports 71 and an axial bore 70 in the valve element 69 to a passage 66, and thence to the throttle valve 54, 55. The piston 67 is acted on by fuel delivered past a fixed restriction 68 from the right hand end of a bore 46 in the rod member 41, the pressure in the right hand end being proportional to the square of the speed at which the apparatus is driven due to the combined action of the centrifugal weights 43 and the valve 48 controlling a bleed path from the bore. Thus the device 64 delivers a pressure which varies in accordance with a constant, dependent on the area ratio of the piston 67 and the valve element 69 multiplied by the square of the speed. This pressure characteristic ensures that for a constant load on the engine supplied by the apparatus the axial position of the rod 41 varies little with variation in engine speed, whereby the axial position of the rod 41 is load dependent. A servopiston 38 for controlling the position of piston 39 movable to adjust the angular position of the injection pump timing cam ring 13 is provided. The pressure established in a branch conduit 45 is used to control the servopiston, and is dependent on variable and fixed restrictions 52/60 and 47. In a modification Fig. 4 (not shown) a valve (75) controls a line which by-passes the restriction 52/60, the valve being open at low engine speeds and being responsive to feedpump pressure and to the delivery from the device 64 to control the opening.

Title: Breathing Aid Administration Device
IPC: A61M16/00
Filed: 1967-08-07
Abstract: 1,189,479. Respiratory apparatus. BRITISH OXYGEN CO. Ltd. 7 Aug., 1967 [10 Aug., 1966], No. 36162/67. Heading A5T. A device for administering a medicinal vapour to a patient comprises a casing with a connection 24 for a source of breathing gas under pressure, a reservoir 6 for the liquid medicament, and an outlet 8 for applying the medicinal vapour to the patient, the casing also including a valve for controlling the flow of the gas from the source to the outlet by way of the reservoir, the valve being arranged so that when the flow of gas is halted the outlet is automatically opened to atmosphere. As shown, by manually depressing a lever 21 a valve stem 15 with a closure flange 14 is moved away from a seat 13 and the gas is able to flow through the nipple 24 into a bore 25 and through fine bores 27 into the liquid medicament. The gas, together with fine liquid droplets, then flows through the outlet duct 8, 30 into a face mask 9 or mouthpiece (Figure 3, not shown) and thence to the patient. The device is arranged so that when the lever 21 is released and the flange 14 arrests the gas flow, the end 16 of the valve stem opens a valve member 17 allowing the gas outlet to communicate through an aperture 35 to atmosphere. The liquid is added to the reservoir 6 by removing a lid 29 and is contained under an apertured baffle 32. The lever 21 acts on the valve stem 15 through an end cap 19, and a spring 36 which loads the valve member 17 is adjustable by rotating a member 37. The device may include a bore 40 in the valve stem 15, the bore by-passing the liquid reservoir so that the proportion of gas in the mixture is increased by an adjustable amount of gas passing directly from the nipple 24 to the gas outlet 8. The by-pass is arranged to operate either by fully depressing the lever 21 or by rotating the valve stem. It is stated that, with no liquid in the reservoir 6, the device may be used for administering gas alone.
