Abstract: 736,133. Filters. PUROLATOR PRODUCTS, Inc. Oct. 1, 1953, No. 26949/53. Class 46. A filter element is fabricated by pleating a strip of filter paper transversely to its length, rolling the strip into an annulus composed of a single layer and having its axis parallel to the line of the pleats, providing adhesive material for adhering the ends of the pleats to annular end caps, applying solvent material to the adhesive material and capping the ends of the pleats with annular end caps. In Fig. 2, tapes 4, 5 of adhesive material (soluble in an appropriate solvent) are applied to the edges of filter paper 1. The paper is then pleated, in the manner shown, either before or after cutting off a length which is thereafter rolled. The edges of the tapes appearing at the ends of the annulus thus formed are moistened with the solvent and caps 8, 9, Fig. 4, preferably of heavy cardboard are applied. In Fig. 5, tapes 13 of an adhesive material which may be stretched in its own plane are applied to the edges of already pleated paper 1 and lengths of the paper thereafter rolled into annular form. Caps are applied as before. In a further modification an annular disc of adhesive is applied to the inside of each end cap, the free surface is moistened with solvents and the caps are applied to the ends of a pleated annulus. Many examples of adhesive materials and corresponding solvents are given.

Filed: 1938-09-15
Abstract: 519,183. Alloys. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 15, 1938, No. 26957. Convention date, Sept. 17, 1937. [Class 82 (i)] [Also in Groups V and XII] Alloys containing a readily oxidizable metal such as aluminium, for example, permanent magnet alloys of the kind described in Specifications 423,897, 424,746, 466,587, and 485,074, or alloys of iron, aluminium and chromium, are made by pressing the mixed powdered ingredients, which may include a brittle preliminary alloy as of iron and aluminium, into the required shape and sintering the pressed material by passing it first through the heating zone of a hydrogen furnace at about 1,400‹C. in the opposite direction to the flow of hydrogen, and then through a cooling zone wherein hydrogen flows in the opposite direction to the flow of hydrogen in the heating zone. Machining may be carried out before sintering or after partial sintering, complete sintering being applied after the machining. In the apparatus shown, the pressed material 19 on boats 20 is pushed slowly through the heating zone 5 of a rectangular tube 4 passing through an electric furnace 1, hydrogen being supplied through a pipe 17 to the tube 4 and through pipes 3 to the furnace 1. Curtains of hydrogen are supplied over the ends 7, 8 of the tube 4. The zone 6 into which the material is quickly pulled from the heating zone 5 is cooled by a water jacket 13, and the material is cooled therein to below 600‹C. to effect precipitation hardening. The boats 20 may be made of a mixture of alumina and metal powder, for example 25 per cent. of alumina and 75 per cent. of iron.

Title: Resuscitator mechanism
IPC: A61M16/00
Filed: 1958-08-22
Abstract: 835,198. Respirators. STANTON, P. L. Aug. 22, 1958 [March 24, 1958], No. 27081/58. Class 81 (2). Respiratory apparatus comprises a chamber connected to a gas supply and to the lungs, flow of gas through the chamber being controlled in response to pressures above and below atmospheric by a piston subjected on one side to atmospheric pressure and on the other to pressure in the chamber. Lower and upper sections la, 1b, Fig. 4, of a body 1 are separated by a gasket 3 and are secured inside a plastic cover 1c so that a chamber 5 open to atmosphere through an opening 6 is formed above the sections. Gas under pressure is supplied by a hose 21 to an intake passage 16, Fig. 8, and through a manually-adjustable needle valve 22 and a port 17 into a valve chamber 9. On inhalation, gas flows from the valve chamber 9 to a mask 2, Fig. 1, supported on the body 1 via a port 8 and a main chamber 7 in the lower section 1a. Negative and positive pressure safety valves 12, 13, Fig. 3, communicate with the main chamber 7. The valve chamber 9 also communicates via a passage 33 with a Venturi tube 28 so that gas can pass via a jet nozzle 34 and the throat 31 of the Venturi tube 28 to atmosphere to effect exhalation. A piston 39, which is reciprocable in a cylinder 38 formed in the upper body section 1b and is subjected to pressure in the main chamber 7, is secured to a spring toggle mechanism 41 in the chamber 5 which is open to atmosphere. One arm 47 of the toggle mechanism 41 is attached to a valve stem 40 having valve members 44, 45 controlling the passage of gas from the valve chamber 9 to the main chamber 7 and the Venturi tube 28 respectively. When the first valve member 44 is open gas is supplied to the chamber 7 and the lungs to effect inhalation, a small amount of gas passing from the main chamber 7 to atmosphere via a suction port 35 and the Venturi tube. Pressure builds up in the chamber 7 during the inhalation phase and on reaching a predetermined maximum moves the piston outwardly of the main chamber. The toggle mechanism 41 snaps over to close the first valve member 44 and open the second valve member 45, thus permitting gas to flow only into the Venturi tube 28 from the valve chamber 9. Gas from the main chamber 7 and the lungs is thus drawn through the suction port 35 to effect an exhalation. When the pressure in the main chamber reaches a predetermined minimum, the piston 39 is moved inwardly of the main chamber 7 to snap over the toggle mechanism and move the valve members 44, 45 into position for inhalation. If the gas supply is sufficiently restricted by the control valve 22, the pressure in the main chamber 7, which is vented continuously through the suction port 35, never becomes sufficiently great to operate the piston and the toggle mechanism to effect the closing of valve member 44. Thus the inhalation phase of operation of the device may be made continuous.

Title: Improvements in or relating to gas separation
IPC: C01B23/00
Filed: 1960-08-15
Abstract: In a process for separating hydrogen out of dissociated ammonia gas, the ammonia gas is compressed to a pressure between 40 and 70 atmospheres, then cooled in a heat-exchanger where part of it (mainly nitrogen) is condensed the condensate separated, and the remaining gaseous part conveyed over a strongly cooled absorbing medium, such as active silica gel or <PICT:0957790/C1/1> carbon, so that impurities (mainly nitrogen) are adsorbed from the gaseous part and substantially pure hydrogen remains. The absorbing medium and heat exchanger are both cooled by means of a cold-gas refrigerator. Referring to Fig. 1 the mixture is compressed to 40-70 atmospheres in the compressor 10 and cooled to about 33 DEG  C. in heat exchanger 12, last traces of undissociated NH3 then being removed in adsorber 14.  The mixture then enters section 21 of the primary heat exchanger 18 via a filter 16. This heat exchanger has tubes 17, 19, 21 and 23, and a chamber 25 containing liquid nitrogen in a quantity which may be varied by a control device 46.  The mixture in tube 21 is cooled to 81 DEG  K. and then contains nitrogen in the condensed state.  It is fed to secondary heat exchanger 20 where N2 is further condensed, the coolant being liquid N2.  The condensate is then separated in a centrifugal separator e.g. cyclone 22.  The remaining gas mixture then passes through demister 24 to absorber 26 which is maintained at the boiling temperature of liquid N2.  The hydrogen gas so formed passes via filter 28 through tube 23 of exchanger 18 to stores e.g. pressure cylinders 30.  The nitrogen condensate withdrawn from cyclone 22 is sprayed into a chamber 32 so that excess hydrogen is released and pure liquid nitrogen can be collected, and may be used as a coolant in the secondary heat exchanger 20 or removed from the system at 32d.  A closed cycle in which pure liquid N2 circulates consists of the cold gas refrigerator 40, absorber 26, heat exchanger chamber 25, and vessel 42 where gaseous N2 is separated and returned for liquefaction. Cyclone 22 and demisters 24 may be arranged inside heat exchanger 20 in a common housing. Specification 763,707 is referred to.

Title: Control means for fluid-pressure-operated apparatus
Inventor: ABBOTT HERBERT GEORGE
IPC: F15B11/22
Filed: 1960-08-15
Abstract: 916,758. Controlling aircraft. DOWTY ROTOL Ltd. July 14, 1961 [Aug. 15, 1960], No. 28233/60. Class 4. Fluid pressure operated apparatus has a flow divider 33 between a pressure source and two motors 13, 14, and a differential mechanism 76 controlled by elements (flaps) 11, 12 to operate divider 33 to maintain the movements of the elements 11, 12 in phase, the divider having valve means to remove the fluid pressure from one motor should pressure be lost in the other. To extend the flaps 11, 12, an electrohydraulic valve 25 controlled by lever and switch 21-23 pressurises line 31 and vents line 30, fluid pressure passing via passages 57, annulus 44, passages 66, 70 to jacks 13, 14. Should the flaps move out of phase, e.g. jack 13 move faster than jack 14, the differential mechanism 76 operated via linkages 74, 75 and 77, 78 displaces valve spool 36 via link 82 to the left, the land 38 increasing the throttling of flow to jack 13 and land 40 decreasing the throttling to jack 14. On full extension, mechanism 76 operates switch 23 to isolate valve 25 to close outlets 28, 29. To retract the flaps, valve 25 directs pressure fluid into line 30 and the jacks, and vents line 31. Fluid displaced by pistons 17, 18 flows respectively via conduits 67, 71, passages 66, 70 and 69, 73, annular spaces 54, 55 passages 58, 60 and 57 to line 31. If jack 13, for example, moves faster than jack 14, spool 36 is moved by mechanism 76, to the right to increase the throttling of flow from jack 13 and decrease it from jack 14 until the jacks move in phase. On full retraction of flaps 11, 12 mechanism 76 operates switch 23 to close valve 25. If during flap extension, a rupture occurs, in conduit 67, aerodynamic forces rapidly retract flap 11; the mechanism 76 then immediately displaces spool 36 to the right to open a valve 52 to place conduit 71 in communication with return conduit 65, aerodynamic forces then retract flap 12. If a rupture occurs in conduit 71, spool 36 is moved to the left to open a valve 47 to vent conduit 67.

Abstract: 449,657. Applying closures to bottles. LIQUID CARBONIC CO., Ltd., Shell Mex House, Victoria Embankment, London. - (Liquid Carbonic Corporation ; 3100, South Kedzie Avenue, Chicago, U.S.A.) Oct. 15, 1935, No. 28512. [Class 125 (ii)] The capping mechanism for fixing crowncorks to bottles is provided with means, such as a plunger 16 and latches 11, arranged so that the sleeve 4 which carries the actual capping device 5, is locked to its carrier 3 during a predetermined portion of the stroke but is released for the remainder of the stroke. By such provision damage due to the supply to the machine of a bottle of abnormal height is prevented. For actuating the latches 11, spring-pressed plunger 16 has a head 16a which contacts with the cork, and at the upper end adjacent the latches a portion 141 that engages with their inner faces so that the noses 14 are forced into and positively held in the groove 15 ; excess movement of the plunger withdraws the portion 14 and at the same time a cam surface 19 engages the lower ends of the latches causing them to pivot and so unlock the sleeve 4 which with the capping head 5 then moves upwards with the plunger. On withdrawal of the bottle, the parts under their respective springs return to their original positions, the latches being forced into the locked condition by a cam surface 18 on the plunger.
