Title: Improvements in or relating to fluid flow control valves
Inventor: KAHN PETER BRUNO
IPC: B64D13/04
Filed: 1961-01-10
Abstract: 1,007,138. Valves. PLESSEY CO. Ltd. Jan. 10, 1962 [Jan. 10, 1961], No. 1067/61. Heading F2V. [Also in Division G3] A fluid-flow control valve includes a conduit 22 through which pressurized media is intended to flow, a first valve 24 serving to shut off in the conduit, and a second valve 9 located in the conduit downstream of the shut-off valve each valve being biased towards its closed position, the second valve being arranged to provide a variable fluid flow area when it is moved between its open and closed positions by a pressure differential produced between a constant value datum pressure tending to open the second valve and derived from a point downstream of the shut-off valve but upstream of the second valve, and a second pressure tending to close the valve and obtained from a point downstream thereof. When the valve 24 is lifted against the resistance of a spring 30 from its seat 23, fluid flows through a duct 33 into a chamber 32 to act on the right-hand side of a web 12 of the valve 9 which is slidably displaced to the left on a fixed boss 1 against the resistance of a spring 30a. The separation of the valve 9 from its seat 16 permits fluid to flow past three equiangularly spaced webs, such as 19, 20, in a Venturi-shaped section of the body into a rear flared portion 21 which communicates with a chamber 31 at the left-hand side of the web 12. Escape of fluid from the chamber 32 is controlled by a duct 35 and a relief valve 34 until sealing means on a sleeve 13 integral with the valve 9 connects the chamber 32 to atmosphere through a calibrated port 52, a duct 53 and a chamber 45 in a solenoid-actuated valve 39. The sealing means also isolate the chamber 31 from atmosphere as the valve 9 opens by closing a port 51. A chamber 24a inside the valve 24 is normally connected to atmosphere through a port 49, ducts 48, 47, and a chamber 44 in the solenoid-actuated valve. When the latter is energized, however, the chamber 44 is connected through a duct 58 to the conduit 22 so that equal fluid pressures are applied to opposite sides of the valve 24 which is then closed by the spring 30. If the valve 9 sticks in an open position the valve 24 is closed in consequence of the movement of the valve 39 to the right by the increase in downstream pressure acting through a duct 46, the valve 39 being locked in the actuated position by a catch plate 56 until manually dis-engaged. The valve may be used in an air supply system for an aircraft cabin, the valve 9 serving additionally as a non-return valve to prevent excess pressure within the cabin.

Abstract: 829,847. Cutting plastic strips. WOLF, P. Jan. 13, 1958 [May 13, 1957], No. 1174/58. Class 87(2). [Also in Group XXX] Strips of confectionery, soap or the like are cut into pieces, and the pieces spaced, by a machine which pushes the strips past cutters and over a grid, whereby alternate cut pieces move along the grid bars and the cut pieces between them are pushed down between the bars on to a conveyer belt and temporarily held back on the belt. A pusher bar 1 is horizontally reciprocated by a cam 27 acting through adjustable linkage 16-23, Fig. 3, and a cross-piece 10 carrying a row of plungers 9 is vertically reciprocated by cams 32 acting through push rods 30. The bar 1 pushes the material through the row of cutting wires 3, so slicing it, and at the same time this material pushes previously cut slices 5a, Fig. 2, along the battens of the grid 7 while the cross-piece 10, descending, brings down the plungers 9 on the pieces 5b between the battens and pushes them on to the conveyer belt 6, where they are temporarily held back by adjustable braking fingers 13 attached to the cross-piece 10, resulting in the cut piece being spread on the conveyer belt at predetermined distances from each other, Fig. 1. The plungers are adjustable by screws 11, Fig. 1, and the cross-piece 10 is adjustably carried on the push rods 30. The length of the slices is adjustable, owing to the link 20 being of variable length and its connection with the lever 22 being adjustable in a slot 21.

Abstract: 684,209. Jolt-ramming machines for making plaster pattern plates. HERRING, J. Jan. 24, 1951 [March 15,1950], No. 1854/51. Class 87 (ii). [Also in Group XXII]  A jolt-ramming machine, for jolting plaster pattern plates &c. is equipped with a compressed air generator, a pressure liquid generator and an electric motor or other means for driving them. In the base of the machine are arranged an electric motor M and air and liquid pumps K, P which it drives. The pump P draws oil from a sump Q and keeps a pressure, regulated by a safety valve A, Fig. 3, in a pipe 2. This has a hand-operated valve D which is operated to raise the plunger a as shown. Then the valve G is opened to supply the jarring plunger s which has means for reversing a valve C to cause it to fall after having lifted the mould d through the desired distance. The falling plunger s strikes the top of the plunger c in which it moves and liquid in the space 4, below the piston a on which c rests, can be forced back through an excess pressure check valve B. This cushioning effect may be increased by introducing some compressed air by a pipe into the space 4 e.g. when jarring plaster pattern plates. The valve G is then closed and a valve E opened to supply liquid below the plunger c to lift the table b and mould d and press this against the usual adjustable swinging head e. The pump K draws air through a filter F and charges a container L having a safety valve H and the compressed air is used for operating an automatic hammer f during pressing and for a cleaning blast. The valve E is then reversed, the weight of the mould and plungers s and c forcing the oil from the space 10 back into the sump. The valve D is then reversed and all the plungers, table b and mould d fall until this is arrested in known manner by vertical rods x mounted on the cylinder g to strip it from the pattern mounted on the table b.

Patent GB-474191-A (GB)
Title: Improvements in the cooling of gases
IPC: F28C3/06
Filed: 1937-01-22
Abstract: Hot gases or vapours are cooled by injecting a liquid of a different chemical nature, preferably water, in a finely distributed state at a temperature which is (a) equal to or above its boiling point at the pressure of the gases to be cooled, and (b) below the temperature of the said gases.  The complete evaporation of the injected water thus ensured is useful in processes, such as the obtaining of gases by roasting pyrites, where the presence of liquid water is deleterious to the constructional materials of the apparatus.  The water, heated directly or indirectly, may be forced through atomizing nozzles arranged in known manner.  The superheated pressure water may be obtained from the feed water for a boiler.  Preferably the temperature of the liquid under pressure should be at least 5 DEG  C. above its boiling point at the gas pressure.  The invention is applicable to exothermic catalytic reactions in which the main part of the gases involved is converted by means of a first contact layer, the final conversion being effected by means of a second contact layer and the gases being cooled between the two stages.  Such processes are used, for example, for producing hydrogen and carbon monoxide from hydrocarbons and steam, or for oxidizing sulphur dioxide, in the synthesis of ammonia from nitrogen and hydrogen, liquefied ammonia being preferably injected in this case between the contact layers for cooling the gas, or in the synthesis of hydrocarbons from carbon monoxide and hydrogen, superheated hydrocarbons being preferably injected between two or more contact layers.  The invention is also useful when products formed are to be prevented from decomposing by cooling them rapidly, as in the production of oxides of nitrogen by combustion of ammonia in the production of unsaturated hydrocarbons by thermal decomposition.  A quantitative example is given to illustrate the application to the cooling of sulphur-containing gases obtained by the Claus process. These gases having a temperature of 400 DEG  C. are cooled down to 150 DEG  C. by the injection of finely atomized water at a temperature of 125 DEG  C., the whole of the sulphur being condensed into the liquid phase.  One third of the sulphur precipitates as a liquid in the vaporizer sump and is continuously withdrawn by means of a heated overflow pipe; the bulk of the sulphur is separated on an electrofilter arranged behind the cooler.
