Title: Improvements relating to conditioning filaments, yarns, fibres, and like materials
IPC: D06M13/224
Filed: 1934-12-19
Abstract: Filaments, yarns, fibres, and like materials, and particularly such materials having a basis of a derivative of cellulose such as cellulose acetate, are conditioned with the aid of tea-seed oil. Materials having a basis of an organic derivative of cellulose may contain pigments or fillers such as powdered metal, metal oxides, or carbonates, lamp black, and opaque organic substances, fire retardants such as b -chlornaphthalene, triphenyl phosphate, and tricresyl phosphate, plasticizers such as diethyl or diamyl phthalate and ethyl toluene sulphonamide, dyes or lakes.  The tea-seed oil may be applied alone or as a solution or emulsion or in conjunction with other substances such as sodium and potassium soaps, oleic acid and other oils.  The conditioning agent may contain a relatively non-volatile substance having a solvent or latent solvent action on the base of the materials, e.g. when treating cellulose acetate, -ethyl oxy-butyrate, benzyl alcohol, diacetone alcohol, or the formals made by condensing an aldehyde with polyhydric alcohols or partial ethers thereof.  The agent may also contain a hygroscopic substance such as a polyhydric alcohol or ethers thereof, and, if desired, a fugitive tint for identification purposes.  The agent may be added to a spinning solution; or applied to materials during production or treatment thereof by means of a wick, roller, disc or other device dipping into a reservoir, by passage of the material through a solution or emulsion of the agent, by spraying, by dipping hanks into the agent, or by forcing the agent through packages of yarn.  In an example cellulose acetate yarn dry spun from an acetone solution contacts as it leaves the spinning cell with a wick partially immersed in tea-seed oil, to apply 1--2 per cent of oil based on the weight of the yarn.  The yarn is twisted and wound on a cap-spinning device.  In another example a solution containing 25 parts of cellulose acetate, 75 parts of acetone, and tea-seed oil equal to 4 per cent of the weight of cellulose acetate is dry spun to form yarn.  In another example conditioning liquid containing 60--70 parts by weight of the formal of the mono-methyl ether of ethylene, glycol, 30--40 parts of tea-seed oil, and 6--12 parts of a 70 per cent aqueous solution of diethylene glycol is applied to cellulose acetate yarn in amounts equal to 4--6 per cent of the weight of the yarn.  The Specification as open to inspection under Sect. 91 comprises also the conditioning of films, foils, and like materials with tea-seed oil.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to electrical circuit-breakers of the air or gas blast type
Inventor: ROX URGH ALBERT
IPC: H01H33/32
Filed: 1956-12-03
Abstract: 883,394. Gas-blast switches; actuation of switches. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 3, 1958 [Dec. 3, 1956], No. 36926/56. Class 38 (5). A gas-blast circuit-breaker has a blast control valve operable by a mechanical connection between an operating spring and the valve or a servo-valve on release of latching means retaining the spring in a stressed condition. As shown, a trip-bar 6 biased to the right by a spring 6.1 is latched by means of a member 8.15 engaging a roller 8.14 on a lever 8.12 pivoted at 8.13 and connected with the bar 6 by a link 8.11 and a lever 8.7 which is pivoted at 8.8. When a trip coil 8.17a is energized a plunger 8.17 strikes the latch 8.15 to release the roller 8.14 and allow the bar 6 to move the valve operating members 6.4, 6.4<SP>1</SP>, 6.4<SP>11</SP> which may be interconnected as described in Specification 882,816. The valves 3 are generally as described in Specification 850,271, the lifting of the fin 31.2 opening the valve so that the air blast passes up the passage 1 to the breaker contacts. Air also passes along the tube 5.3 to a cylinder 5.2 and acts on a piston 5.1 tending to open the isolators which are coupled, as described in Specification 882,817, to a bar 5 for opening and to a bar 4 for closing. Latches 4.12 and 4.21 act on the linkwork coupled to the bar 4 and although the air in a pipe 5.3a acts on a piston 4.15 to immediately release the latch 4,12 the release of the latch 4.21 is delayed since the air supply to its operating piston 4.23 has to pass through a restricted orifice at 4.26. When the latch 4.21 is tripped the piston 5.1 moves up to open the isolators and uncovers a pipe 8.3 leading to a cylinder 8.2 with a piston 8.1 carrying a plunger 86 which resets the lever 8.7 and the bar 6, the latch 8.15 being reset by a piston 8.20 and plunger 8.21. A closing coil 9.6 operates a pilot valve 9.5 so that a servo-valve 9.3 admits air to a cylinder 8.1 and piston 9 driving a lever 7.9 clockwise about its other end to operate a double valve 7 connecting the isolator closing cylinder 42 to the air supply. The latch 4.12 is shaped so that its biasing spring 4.14 assists the isolator closing movement when the isolator contacts are within arcing distance. If the bar 6 is released during a closing operation a lever 7.17 displaces a latch 7.14 allowing the upper end of the lever 7.9 to move to the right and reverse the valve 7, cutting of the air supply to the cylinder 4.2. A valve 10.1 ... 10.3 may be provided to prevent air being supplied to the local reservoir during a circuit-breaking operation. Specification 882,818 also is referred to.

Other fixing arrangements for the plates 24 may comprise a co-operating lugs (29, 30, Fig. 5), on both the plates 4 and 24 adapted to receive a locating pin (31); b bent-over lugs (32, Figs. 6 and 7), on the plate 4, apertures (33) in which are fitted over corresponding protrusions (36) at the ends of plates 24. The header covers 15 rest on ledges 14 formed at the open end of each header box 7, the covers being secured in position by the bending over of tabs 13 on the header box (see Fig. 3), Pipes 17 (and 17a, Figs 4 and 8), convey fluid to or from the heat exchanger, and a sleeve (42, Fig. 8), may interconnect the pipes 17a of adjacent heat exchangers where two or more of these are interconnected to form a larger unit. In such a unit the internal fin elements 28 may be of different length or form in the respective heat exchangers. The heat exchanger may be mounted from extensions (not shown), of the intermediate plates 4 or by means of pins or hooks projecting from the bosses 21 on the plates 4.

Patent GB-1038148-A (GB)
Title: Continuous mashing process
IPC: C12C7/04
Filed: 1963-09-20
Abstract: A continuous mashing process involves establishing a reservoir of mash, maintaining the temperature of the mash at conversion temperature (140 DEG -158 DEG F.), continuously withdrawing from the reservoir a stream of converted mash, continuously adding to the reservoir preheated mash at essentially the same rate as the withdrawal of converted mash and withdrawing the converted mash by pumping by a swept surface heat exchange pump to heat the mash to a temperature at which enzymatic action is destroyed (165 DEG -180 DEG F.).  The preheated mash added to the reservoir may be obtained by establishing a further reservoir at proteolysis temperature (115 DEG -120 DEG F) and employing a second swept surface heat exchange pump to pump the proteolysed mash to the first reservoir and to raise the temperature of that mash to conversion temperature.  The hot, converted mash may be delivered to a lauter unit.

The outlet of the combustion chamber is connected to a device for recovering heat from the products of combustion. The apparatus shown comprises a combustion chamber 1 having air intakes 4 controlled by non-return valves 5, air passing through the tubes 6 into the chamber 1. A fuel injection device 2 supplied from a pump 3, and an igniter 7 are also provided. The combustion chamber 1 is connected to a discharge duct 8 and the combustion chamber and discharge duct are enclosed in a container 11 which may be supplied with water so as to constitute a hot water boiler or a steam generator.
