Title: Improvements relating to flying helmets
Inventor: LOBELLE MARCEL JULES ODILON
IPC: A42B3/18
Filed: 1961-03-14
Abstract: 1,005,187. Respiratory appliances. M. L. AVIATION CO. Ltd. March 9, 1962 [March 14, 1961], No. 9315/61. Heading AST. [Also in Division A3] A flying helmet has an oxygen mask 8 and ear buns 21, 22 which are movable inwardly towards the centre of the helmet against a bias on operation of a control means 36 to 40. The mask is secured by a resilient neck 9 to the front of the helmet which has a face opening 2 closable by a visor 3. The ends of a resilient pad 11 arranged over the mask are interconnected a cord 14, 15, 18, 19, 29, 30 which passes round the sides and back of the head and is supported in guides 27, 28 on the ear buns and in eyelets 31, 32 fixed to the helment. Near the rear of the helmet, the cord is attached to a further cord 34 wound on a capstan 36 which is operated through a gear 38 by a hand wheel 39 on the outside of the helmet. The ear buns are normally held away from the head by pairs of spring arms 23, 24 connected to the crown of the helmet On winding the further cord on the capstan, the cord interconnecting the two ends of the maskcovering pad is tightened to cause the application of the mask and the ear buns to the head of the wearer against the resilience of the flexible neck and the spring arms, respectively. Temple pads 43 and a back pad 47 are similarly normally held away from the head of the wearer by spring arms 45 and leaf springs 48, 49, respectively, and may be moved against the head of the wearer by tightening a cord 54<SP>1</SP> on rotating a second capstan 66 by a handwheel 73. A further pad 68 or a webbing harness may be supported within the crown of the helmet by leaf springs. Specification 1,005,186 is referred to.

Title: Improvements in or relating to systems for conveying and counting flat articles
IPC: G06M7/08
Filed: 1958-03-24
Abstract: 868,654. Photo-electric counting. IGRANIC ELECTRIC CO. Ltd. March 24, 1958 [April 4, 1957], No. 9323/58. Class 40(3) [Also in Group XXX] In a system for counting flat, flexible articles, e.g. folded newspapers, the articles are conveyed between endless wires 10, 11 until they reach a point where wires 11 are reversed around a drum 14, beyond which the articles are engaged by downwardly moving runs of endless wires 15 which cause the articles to be flipped in turn through a light beam 24 emanating from a source 25 and impinging on a photo-cell 26. A second light beam 27 passes upwardly from a light source 28 to a mirror 29 and thence to the photo-cell 26, this second light beam intersecting the path of the articles at a point in advance of the light beam 24. The photo-cell 26 is connected to a counter mechanism so arranged that a count is made only when both beams 24 and 27 are broken. This is said to avoid an article being counted twice as a result of its tail end flipping upwardly through the beam 24 after its forward end has passed downwardly through the beam 24. Instead of the second beam 27 passing to the same photo-cell as the beam 24 it may pass to a second photo-cell which replaces the mirror 29, the two photo-cells being in this arrangement connected in parallel in a counting circuit arranged to respond only when the light beams impinging on both photo-cells are broken simultaneously.

Filed: 1957-03-21
Abstract: 833,570. Discharge apparatus. HILGER, & WATTS Ltd. June 23, 1958 [March 21, 1957]. No. 9352/57. Class 39(1). [Also in Groups XI, XX and XXXV] In order to carry out a quantitative spectroscopic analysis of a substance (see Group XX) a sample 1 of the substance is introduced by a rod 3 into a vacuum chamber, and the rod is rotated so that the sample falls into crucible 7 in the lower part of the chamber. The temperature of the sample is then raised sufficiently to vaporize it, by heating the crucible with an electron beam from a hot cathode 9, this heating being controlled by a D.C. voltage from supply 10, which is fed with an error signal equal to the difference between the current corresponding to the temperature of the sample, as measured by a photo-electric pyrometer 11, 19, and a predetermined current corresponding to the requirements of the analysis in question. In order that the crucible surface shall have a high emissivity, it is provided with grooves 12, and the ratio of crucible diameter to the diameter of the surrounding radiation shields 8 is as low as practically possible. The vapour may be excited to emit the characteristic spectrum of the sample by heating the latter to a sufficiently high temperature. Alternatively, the vapour may be heated by a glow discharge between electrodes comprising the mouth of the crucible and of a diffuser 16, separated by an insulator 21, or by an electron beam directed on to the vapour. This electron beam may be reflected by a reflector electrode to produce standing electro-magnetic waves and plasma oscillations. Ultra high frequency oscillations may also act on the vapour stream.

Title: Improvements in or relating to jet wheel motors
IPC: F01D1/12
Filed: 1921-03-29
Abstract: 177,989. Johnson, A. B. March 29, 1921. Jet-wheels; circular-flow type; balancing moving parts. - Two inter-meshing jet-wheel rotors are geared together externally of their casing so that their blades may inter-mesh without contact. The blades have an edge portion 33 and end portion 34 forming buckets, recesses being formed on the rotors so that the blades are steam-tight. High-pressure steam is admitted through nozzles 35, at a point just above the line joining the shafts and on both sides of the rotor casing, to discharge at an angle on to the blades of both rotors. A downwardly extending projection 36 cuts off some of the steam which is led to intermediate receivers 37 for each rotor whence it discharges through nozzles 38 on to the blades and passes to low-pressure receivers 39 having inlet guides 42 finally discharging through nozzles 40 on to the blades again and then to the exhaust 45; the receivers for one rotor are arranged reversely to those of the other rotor.

Title: Improvements in or relating to a compressor control
IPC: F04B49/00
Filed: 1963-03-08
Abstract: 982,655. Fluid-pressure servomotor control systems. COOPER-BESSEMER S. A. March 8, 1963 [March 19, 1962], No. 9422/63. Heading G3P. The compression ratio of a compressor is varied in accordance with the algebraic sum of the inlet and outlet pressures to maintain the power input to the compressor substantially constant. The compressor has double acting cylinders C-1, C-2, an inlet duct 14 and an outlet duct 16, the compressor being driven by an engine 10. The inlet pressure acts on a piston 36 and the outlet pressure on a piston 26, the movements of the pistons causing movement of a stylus 20 in directions at right angles to each other. The stylus contacts a plate 44 divided into electrically insulated segments a,b,c,d and e, the areas of these segments representing a summation of the inlet and outlet pressures at which the compressor operates at substantially constant horse power. When the stylus is contacting segment a a current flows to a time delay relay 53a to cause closure of a switch 54a which energizes a coil 52a of a solenoid valve 50a. When the valve 50a is energized, fluid pressure from a leader 60 flows to open unloading valves A-1, A-4 to reduce the compression ratio. When the stylus moves to segment b due to an increase in suction or discharge pressure without a variation in the other pressure, current flows to a relay 53b to close switches 54b, 55b. Closure of the switch 55b provides a holding current for relay 53a to maintain the solenoid 52a  energized and switch 54b energizes coil 52b of solenoid valve 50b to open the unloader valve A-4 Similarly when the stylus moves over segments c,d and e further unloader valves are opened while holding the opening of the previous unloader valves. The stylus and plate may be replaced by a photo-electric cell and a plate having segments of varying density. A conventional speed governor 62 may be provided for the engine.

Title: Improvements in or relating to paper feeding mechanism for statistical and like machines
Filed: 1941-07-26
Abstract: 554,991. Feeding sheets. REMINGTON RAND, Inc. July 26, 11941. No. 9509. Convention date, Aug. 17, 1940. [Class 117] [Also in Group XVI] In statistical and like machines sheets stacked in a magazine are fed successively by a pickerknife which, when in inactive position, retains the edge of the fed sheet tightly pressed against feed-rollers when the latter are stationary. As shown, a pile of sheets is placed on a reciprocating table 90 and is confined at the sides and rear by brackets 98, 100, and at the front by a throat-member 101. The table is provided with blocks 92, 104, slidably mounted on a bar 86 which is secured to the tabulatorframework 20. The sheets are bent upwards at the middle by means of the curved top 94 of the block 92 and a curved plate 97 secured to the table. The table may have side-strips 96 for bending the sheets upwards at the sides. The block 92 carries a bottom-feed picker 103 having the same curvature as the face 94. The throatmember 101 and a block 132 are separated by a curved throat which is slightly deeper than the thickness of a sheet. The throat-member 101 is carried by a shaft 135 and is held in normal position by springs 136. The shaft is moounted eccentrically in a collar 138 which is clamped in a block 137 carried by the bar 80, and can be turned to adjust the throat. Mechanism for reciprocating the table comprises a rock-plate 207 connected by a slotted link 114 to an arm 122 on a rock-shaft 109 which is provided also with a spring-urged arm 111 and an arm 108 which is connected by a link 107 to the block 104. During each cycle, the picker moves rearwardly until it engages the rear edge of the bottom sheet 116a, and then moves forwardly to feed the sheet and press the front edge tightly against feed-rollers 64, 73, when the latter are stationary. Guides 118, 1119 direct the sheet. The upward bend formed in the middle of the sheet by the members 94, 97 provides a defined stiff edge for co-operation with the picker.

Title: Process for the production of derivatives of vat dyes and the dyeing of non-cellulosic textile materials therewith
IPC: D06P1/22
Filed: 1953-04-09
Abstract: In the dyeing or printing of textile materials consisting of or containing non-cellulosic fibres with vat dyestuffs, the material is impregnated with an acid leuco vat dye, which has been prepared by reducing a vat dye at an elevated temperature, preferably above 60 DEG C., by means of thiourea dioxide in the presence of a cationic surface active agent, and then submitted to oxidation. The acid leuco derivative is preferably formed in situ by impregnating or printing the material with a mixture of the vat dye, thiourea dioxide and the cationic agent and then heating Specified cationic agents are quaternary ammonium compounds such as cetyl trimethyl ammonium bromide and pyridinium or morpholinium compounds.  The process is particularly applicable to cellulose acetate fibres, if desired in admixture with wool, silk, nylon and polyester fibres; mixed fabrics of wool and cotton may also be treated.  Examples describe the dyeing of cellulose acetate and cellulose acetate-nylon fabrics, additions to the dyebath being ethylene glycol diacetate, acid sodium phosphates and hexylene glycol.  Another example describes the printing of a wool-cotton fabric with a paste containing a vat dye, thiourea dioxide, cetyl trimethyl ammonium bromide, polyethylene glycol, glycerol and British gum-tragacanth thickener, the printed fabric then being dried, steamed, rinsed and oxidized with aqueous sodium percarbonate.

Abstract: 1,259,861. Biaxially orientated nitrile polymer film. STANDARD OIL CO. 24 Feb., 1969, No. 9676/69. Heading B5B. [Also in Division C3] Impact resistant, biaxially oriented nitrile polymer films are made by (1) forming a solution in a volatile polar organic solvent of a homopolymer or copolymer of a nitrile monomer having the structure wherein R is hydrogen, halogen or methyl, the copolymer containing up to 30% by weight of a mono-alkenyl or polyalkenyl monomer copolymerizable with the nitrile monomer; (2) forming a film containing 8-60%, preferably 25-45%, by weight, of solvent from the solution; (3) stretching the film at 100-260‹ F., preferably from about 145‹ to 180‹F., in a longitudinal and a transverse direction so that the film contains at least one half the percentage by weight of polar solvent that it contained at the end of step (2); drying and heat-setting the film at 257-482‹ F. for from less than 1 second up to 5 minutes preferably from less than one second up to about 60 seconds while it is retained in its biaxially stretched condition; and (5) quenching the film while still under tension by rapidly cooling to a temperature not exceeding 100‹ F. The polymers used in the examples are a copolymer of acrylonitrile with 0À3% by wt. of butanediol-1,4-divinyl ether, a homopolymer of acrylonitrite, a copolymer of acrylonitrile with 0À4% by weight of divinyl benzene, and a copolymer of 70% by weight acrylonitrile and 30% by weight ethylacrylate. The solvent used in the examples is a 90/10 mixture of dimethyl formamide and ethylene carbonate. In an example, a copolymer of 99À7% by weight of acrylonitrile and 0À3% by weight of butanediol- 1,4-divinyl ether is dissolved in a 90/10 mixture of dimethyl formamide and ethylene carbonate to form a 17% solution of the polymer, the solution is cast on to a stainless steel endless travelling belt at about 160‹ F. and dried in an oven to form a film containing 15% by weight of dimethyl formamide and 21% by weight of ethylene carbonate. The film is longitudinally drawn at a stretch ratio of about 3 : 1 using a feed and draw roll stretching apparatus in which the feed rolls are maintained at about 160‹ F. The film is then stretched transversely at a stretch ratio of 2À8 : 1 by means of a tentering apparatus in which the oven stretch zone temperature is maintained at 160‹ F. After this operation the film contained no dimethyl formamide and 16% by weight ethylene carbonate. The resulting biaxially oriented film is passed through the heat-setting zone of the tenter frame oven, maintained at 400‹ F., the period of residence in this zone being 30 seconds. The ethylene carbonate content of the film had been reduced to below 1%.
