IPC: F15B13/043
Abstract: 1,053,296. Valves. DUNFORD & ELLIOT PROCESS ENGINEERING Ltd. Sept. 27, 1963 [Sept. 11, 1962], No. 34731/62. Heading F2V. A three-part valve body 1, 2, 3 has an inlet 5 in the part 1 communicating with respective ends of two piston valves 24, 36 movable in sleeves 19, 20 and 31, 32 respectively. The sleeves have external annular grooves 23, 35 which communicate with the interiors of the sleeves and with respective outlets (not shown) in regions 13, 14 of the bores housing the sleeves. Larger diameter heads 29, 41 of the pistons are exposed to pressure in a control chamber 43 which communicates with inlet 5 through a passage 8, 79 and an orifice 47, Fig. 3 (not shown), of an adjustable plug housed in the wall of body part 3. A second adjustable plug 53 aligned in the opposite wall communicates with the atmosphere. A needle pilot valve 59 is movable with small clearance between the plugs 45, 53, whereby the control chamber is alternately placed in communication with the inlet 5 or with atmosphere. A spring 63 normally urges the pilot valve to the position which vents the chamber. This spring acts against an iron cross plate 62 carried by the pilot valve and forming an armature which co-operates with polepieces 64, 65 of electromagnets 66, 67 housed in the chamber. In the position shown, the chamber 43 is vented, valve 24 being closed and valve 36 open; when the chamber is pressurized, both valves move upwardly to reverse this condition. The space above the larger diameter heads is permanently vented at 11, 12. The pilot valve may be energized through electronic means.

Abstract: 1,227,153. Photo-electric position finder. BRITISH AIRCRAFT CORP. Ltd. 14 Aug., 1969 [14 Aug., 1968], No. 38959/68. Heading H4D. A transmitter for a guidance system has a source of a beam of radiation 41 illuminating a reticle 37 divided into alternate bands of differing opacities, two optically flat plates 10, 11 one on each side of the reticle 37 inclined to one another such that the beam is displaced laterally by equal amounts in opposite directions by each plate, and means for rotating the plates 10, 11 conjointly about the axis of the reticle. In a system for guiding a vehicle in a straight line the plates 10, 11 are mounted in casings 28, 29 which are supported in bearing assemblies 22, 23 in a fixed housing 27. The casings are rotated by a constant speed drive through gears 32, 34 at each end of the drive shaft 33 engaging gears 31, 35 on the casings. The rotation of the plates causes the centre portion 17 of the infrared or visible light beam 41 to rotate about the centre of the reticle which may be divided into equiangular alternate areas of different opacity or the areas may be Archimedean spirals. The beam 17 is deflected by an amount not less than half the beam width and not more than the radius of the reticle. The fixed beam of light 20 leaving the transmitter thus is modulated over its area according to the relative widths and opacities of the alternate areas. The receiver is mounted on the vehicle, e.g. as described in Specification 1,046,024, and detects the varying modulation over the cross-section of the beam to enable it to correct deviation from the desired course.

Abstract: 1,230,778. Jet propulsion nozzles. ROLLS ROYCE Ltd. Aug. 5, 1968 [Aug. 15, 1967], No.37352/67. Heading F1J. Apparatus for controlling the flow of fluid through a duct, such as the propulsion nozzle of a gas turbine engine, comprises an annular arrangement of pivotal flaps mounted on or in the duct and movable by piston and cylinder fluid-pressure motors connected directly, without any intermediary mechanism, between the respective flaps and an annular support member disposed coaxially with the flaps. In one embodiment, alternate flaps 11 are pivotally mounted by transverse pins 14 to a jet pipe 10 and carry integral pistons 12 each slidable in a curved cylinder 13. Sealing is effected by a piston ring 21 mounted on a grooved flange 22 on each piston 12. The cylinders 13 are connected to or integral with an annular support ring 16 containing a chamber 16b communicating with each cylinder through a duct 15. A valve 18 controls the flow of pressure fluid to and from chamber 16b through a duct 17 for operation of the flaps 11. The flaps 11a adjacent flaps 11 follow the movement of the latter by interengagement therewith. In a modification, the chamber 16b can be separate from ring 16. In further modifications, Figs. 4, 5 (not shown), the wall containing duct 15 and separating each cylinder from the chamber 16b is eliminated and sealing between each piston (30) and its cylinder (33) is effected by a ring (31) located in a groove (32) in the cylinder wall at the end of the cylinder adjacent the flap 11. In an alternative construction, the cylinders 13 (or 33) can be fixed to the flaps 11 and the pistons 12 (or 30) fixed to the support ring 16. The pistons and cylinders instead of being of circular cross-section, as shown, may be square or rectangular. In a further modification, the flaps are arranged on a centre body in the propulsion nozzle and are connected directly by fluid-pressure motors to a support member lying inside the flap annulus.

Abstract: 1,252,203. Automatic mixture control. MARATHON OIL CO. June 5, 1969 [June 5, 1968], No.28491/69. Heading G3R. The proportion of a fluid in a mixture is periodically detected by the peak voltage output of a chromatograph which is compared with a voltage corresponding to a desired proportion and the difference converted into a current pulse of corresponding duration for timing the addition of fluid to the mixture to correct the proportion. As applied to a reactor supplied with olefines and bisulphite to produce sulphonates, switch contacts operated by a timer motor periodically energize a solenoid valve to supply samples of the reaction gas to a chromatograph which adjusts a potentiometer 36, Fig. 2, to a position corresponding to the oxygen content of each sample. Under these conditions a condenser 46 is connected to terminals 56, 58 so that it is charged to a voltage corresponding to the difference between the actual oxygen content voltage from potentiometer 36 and a desired oxygen content voltage set by a potentiometer 34. A voltage corresponding to the actual oxygen content is stored in a condenser 44 and, when potentiometer starts to return from its highest position, transistors Q 1 -Q 3  are operated to de-energize a relay K 2  which through a relay circuit (not shown), connects condenser 46 as shown to operate transistors Q 4 -Q 7  and energize a relay K 3  so that a solenoid valve (not shown) is opened to supply oxygen to the reactor. Relay K 3  remains operated until condenser 46 discharges to a predetermined voltage through a resistor 60-66 which is selected to produce a desired correspondence between the duration of the oxygen supply and the magnitude of the oxygen deficiency.

Abstract: 1,252,222. Hydrogen. EUROPEAN ATOMIC ENERGY COMMUNITY. 21 Jan., 1970 [19 Feb., 1969], No. 3009/70. Heading C1A. A process for the production of hydrogen is based on a cycle of reactions which comprise: (1) Reacting mercury with hydrogen bromide to form mercuric bromide and hydrogen (2) reacting the mercuric bromide with an alkaline earth metal hydroxide to form an alkaline earth bromide, mercuric oxide and water (3) decomposing the mercuric oxide to give mercury and oxygen (4) hydrolysing the alkaline earth bromide to form the alkaline earth hydroxide and hydrogen bromide, the reaction products hydrogen bromide, mercury and, preferably, the alkaline earth hydroxide are recycled to the reaction system. For reaction (1) the temperature range may be between 25‹ and 300‹ C. The hydrogen bromide may be in liquid or gaseous form, or in solution, and the reaction may be carried out at elevated pressure. In reaction (2) temperature may be in the range 90-100‹ C., and it is preferred to use an excess of alkaline earth metal hydroxide. Specified alkaline earth metal hydroxides are Ca(OH) 2 , Sr(OH) 2  and Ba(OH) 2 . Reaction (3) takes place under normal pressure at a temperature between 500‹ and 600‹ C. Reaction (4) is preferably carried out at 600- 750‹ C. at elevated pressure; this may be accomplished by heating the starting materials in a closed container. Alternatively the alkaline earth metal bromide may be heated at normal pressure in a current of water vapour, and the water vapour condensed to recover the HBr.
