Title: A high-pressure gas inlet valve device for a respiratory apparatus
IPC: A62B9/02
Filed: 1966-06-16
Abstract: 1,100,996. High-pressure gas inlet valve device for a respiratory apparatus. O. H. DRAGER, [trading as DRAGERWERK, HEINR. & BERNH. DRAGER], 16 June 1966 [16 June, 1965], No. 27041/66. Heading AST. A high-pressure gas inlet valve device for a respiratory apparatus is illustrated with reference to the drawing and comprises a pressure-reducing valve C which serves to reduce the pressure of high-pressure gas to a low pressure, a lung-controlled valve B located downstream of said valve C and serving to reduce the pressure of the gas from said lowpressure to respiratory pressure, and a valve housing A common to both valves. The device illustrated by the drawing is connectable at the upper end by a union nut 1 to a shut-off valve of a high-pressure nutrient gas bottle, and at the lower end the device is connected to a breathing bag 25. The nutrient gas flows through bore 3 into inlet chamber 4 and past closure member 5 into the outlet chamber 13 of valve C where expansion and pressure reduction occur. The low-pressure gas flows through bore 15 into antechamber 16 of the valve B. Operation of the rocking arm 19 allows gas at respiratory pressure to flow into bag 25.

Title: Improved method of and means for the preparation of fibres for spinning
IPC: B65H54/78
Filed: 1945-10-16
Abstract: 606,686. Preparing fibres for spinning. DUNKERLEY, F., and ALDINGTON, F. Oct. 16, 1945, No. 27082. [Classes 120(i) and 120(iii)] In the preparation of fibres for spinning, the fibres are formed into slivers and the slivers are formed into a band in which the fibres are wholly or partially parallelized, the band being delivered through a laying device into a substantially rectanguler can. As shown, card slivers pass through drawing rollers, condensing funnels 10, and calender rollers 11 and are laid side by side or slightly overlapping upon a travelling lattice 12 which conveys them to compressing rollers 14 which cause the slivers to adhere to form an even flat band 20. From the compressing rollers, band 20 is led over a take-up device comprising pivoted plates 15, 16, which leads the band to a laying device comprising a reciprocating carriage 17 driven by a cable 21 running round a pulley 25 oscillated by a crank 26 and arm 27. Spring loaded, driven calender rollers 28 in carriage 17 take up the band 20 through guide plates 29 and lay it in a rectangular can 30. Cans 30 are arranged on a travelling lattice 31, and when one can contains sufficient material as measured by an electric measuring mechanism connected to rollers 14 or some other part of the apparatus, it is caused to move on and is replaced by an empty can. The band 20 may be automatically severed as the can is changed. From the rectangular can, the band may be led to a drawing frame, preferably provided with trumpet condensers as described in Specification 487,630, a single band from a rectangular can replacing a plurality of slivers from a number of the usual round cans. 42 card slivers of cotton may be drawn and led in threes through funnels 10 to produce 14 slivers which are formed into a band about 3¢ inches to 5 inches wide. The rectangular cans may be about 5 inches wide, 22 inches long and 40 inches deep, and may be mounted on castors.

Abstract: 1486363 Coking bituminous coal HOUILLERES DU BASSIN DE LORRAINE 26 June 1975 [27 June 1974] 27147/75 Heading C5E In a coke manufacturing process in which bituminous coal is passed downwardly through an inclined rotating tubular oven 1 and the heat required for carbonization is provided by combustion of volatiles evolved from the coal, combustion air is introduced into the oven, at a position between the coke outlet and the zone at which the coke reaches maximum carbonization temperature, in an amount in excess of that necessary to bring the coke to the maximum carbonisation temperature, and an endothermic fluid such as water or flue gases is introduced into the oven in an amount sufficient to maintain the desired carbonization temperature; the supply of combustion air and endothermic fluid is regulated to ensure that the temperature of the gases issuing from the oven is kept above 600 C. and that the carbonization is carried out at 600-1100 C. The bituminous coal used has greater that 15% volatiles content and a swelling index between 1 and 8. In the apparatus shown, combustion air is fed via fan 9 and water via tube 11. Pyrometric devices 17 spaced along the oven are connected via control circuits to valves 18, 19 in the air and water intake lines. Further combustion air may be provided along the oven by fans 14, 15, 16. The coking process is controlled, either by adjustment of the speed of rotation of the oven or by providing a widened portion of the oven, to provide a zone of lowest temperature rise of 10-15 C. per minute in the temperature range 300-100 C.

Title: Improved process for the flotation treatment of ores and minerals
IPC: B03D1/001
Filed: 1930-09-12
Abstract: In concentrating by flotation ores and minerals the solubility of which exceeds 0,04 gm. per litre the solubility of the ore or mineral to be floated is diminished by the addition of the same ions as those liberated in the solution by the ore or mineral.  In concentrating sulphates, e.g. gypsum, a sulphate solution is added, for example calcium sulphate, and in treating minerals sending halogen ions into solution, halides are used.  The Specification as open to inspection under Sect. 91 (3) (a) describes the flotation of cryolite with the addition of sodium fluoride to the pulp.  This subject-matter does not appear in the Specification as accepted.

Abstract: 873,702. Manifolding papers. CARIBONUM Ltd. July 24, 1959 [Aug. 26, 1958], No. 27365/58. Class 96. A sheet of manifolding paper is coated on one side with a transferable composition comprising a colour-forming leucauramine derivative such as 10 - (4 - N - leucauramine - benzoyl) - 3,7- bis - (dimethylamino) - phenothiazine, as disclosed in Specification 817,564, morpholinylleucauramine, piperidyl-leucauramine, piperazyl-dileucauramine or monocarbethoxy-piperazyl-leucauramine, and a stabilizer such as pbenzylaminophenol, diphenylamine, N-phenyl- 2-naphthylamine, or a salt thereof such as the hydrochloride, or 1,5-dihydroxy-naphthalene. The other side of the sheet, or a separate copy sheet, is coated with a non-transferable colourless acidic composition capable of reacting with the leucauramine derivative to form a colour. The acidic composition may comprise tannin and phosphotungstic acid, as described in Specification 852,131. When two or more sheets are assembled in a manifold pack with transferable and non-transferable coatings touching, pressure exerted, as by writing, on the uppermost sheet, transfers corresponding portions of one or more transferable coatings on to one or more non-transferable coatings, and a reaction occurs producing a coloured, e.g. blue, copy on the underlying sheet or sheets. The transferable composition may also comprise gelatine, precipitated calcium carbonate, titanium dioxide, soda ash, an emulsifying agent, a fungicide, sextol phthalate and tricresyl phosphate. It is stated that yellow or brown discoloration of the manifolding paper, caused by exposure to light, is prevented by the stabilizer. The amount of the latter may range from 0.05 to 0.5% by weight, of the transferable composition.

When the resistance to the movement of pistons 36 increases, back pressure lifts a seal 34 from a seat 21 thus allowing the check-valve 31, which has been held open by a member 22, to close. Fluid now passes to the underside of a differential piston 25, 27 so that as piston 25 is raised a higher pressure is applied between the pistons 36. At a higher preset pressure a relief valve 37 opens allowing fluid to return to a reservoir 13. When this occurs a ball 42 moves a reset knob 45 upwards and is held in the open position by a plunger 40 until reset against the action of a spring 43a. The reservoir 13 contains a bladder 14 which inflates due to atmospheric pressure as liquid is drawn from the reservoir.
