Patent GB-1264624-A (GB)
IPC: D01F6/00
Filed: 1968-12-23
Abstract: 1,264,624. Fibrillated filaments. UNION CARBIDE CORP. 23 Dec., 1968 [26 Dec., 1967], No. 61099/68. Heading B5B. [Also in Division D2] Fibres used for pulp or paper manufacture are prepared by fibrillating filaments of thermoplastics materials, each of which filaments contain at least three melt-extrudable polymers that are immiscible with one another in the molten state. One of the polymers is a polyvinyl ester hydrolysed to the extent of 30 to 60% by weight, and at least two others have overlapping orientation-temperature ranges. Preferably these two are polyethylene and polystyrene, but reference is also made to polyolefines generally, polyamides, polyesters, polyethers, polyurethanes, polycarbonates, polysulphones, polymers of methacrylic esters, and polymers and copolymers of vinyl esters. The polyvinyl ester for hydrolysis may be made by polymerization in the presence of a polymeric interfacial agent, e.g. a copolymer or graft polymer of an alpha-olefine with a vinyl ester, a polyvinyl alkyl ether, a propylene oxide rubber or a butadiene-styrene rubber, and may be hydrolysed in the presence of basic or acidic catalysts. The three polymers may be fluxed together at elevated temperature, melt extruded into filaments, oriented by cold drawing and fibrillated by chopping and beating in water. Reference has been directed by the Comptroller to Specification 836,328.

Abstract: 1288913 High - temperature reactions UNITED STATES BORAX & CHEMICAL CORP 15 Dec 1969 [18 Dec 1968] 60164/68 Heading C1A High-temperature reactions, e.g. the preparation of boron from BCl 3  and hydrogen, are effected by injecting at least one reactant into a plasma formed by R.F. coupling in a stream of inert gas and/or another reactant downstream of the centre of the plasma, as described in Specification 1,194,415, with cooling of the plasma by indirect heat exchange in the plasma formation zone and preferably also in the reaction zone. The cooling may be effected by passing a coolant, e.g. water or a fluorinated hydrocarbon, through channels surrounding the region to be cooled, and a suitable apparatus for the process is described and claimed, being similar to that described in Specification 1,194,415 with the addition of a water jacket around the reaction vessel.

Abstract: 1289565 Relay circuits INTERNATIONAL BUSINESS MACHINES CORP 4 Sept 1970 [16 Sept 1969] 42418/70 Heading H3T A circuit for energizing the coil Bo of an electromagnetic relay, e.g. in telegraphy, so that its contacts are closed for the same length of time as an input signal comprises an electrical storage element and is arranged to detect the response time #t 1  between energization and closure of the contacts, and the time #t 2  between de-energization and opening of the contacts, and to delay energization by a time #t 3  following an energization command signal (start of an input signal) and to delay deenergization by a time #t 4  following a deenergization command signal (end of an input signal), the delays being such as to satisfy the equation #t 1  - #t 2  = #t 4  - #t 3 . In the embodiment the " off " delay #t 4  is made equal to the " on " response time #t 1  and the " on " delay #t 3  is made equal to the " off " response time #t 2 . The storage element is a capacitor C and it is shown how this is charged from a voltage Vb towards + V through a circuit having a first time constant for the time #t 2  following deenergization of Bo until the contacts B separate, and that this charge is dissipated through a circuit having the same time constant following an " on " command signal at I. This signal causes T1 to conduct immediately and T2, T3 and T4 conduct to energize Bo when the charge on C has dropped back to Vb, thus introducing the delay #t 3  equal to #t 2 . When T4 is conducting and until the contacts B close (i.e. time #t 1 ) the capacitor continues to discharge, through a circuit with a second time constant. When the input signal ends (off command) T1 goes off immediately but T2, T3, T4 remain on while C recharges up to Vb through a circuit having the second time constant, thus producing the delay #t 4 , equal to #t 1 . Thus the total time between " on " command and closure of contacts B is made equal to the total time between " off ' command and opening of the contacts B.

Abstract: 1295747 Containers TRANE CO 17 Sept 1970 [26 Sept 1969] 44509/70 Heading F4H [Also in Division H2]  A refrigeration system for use with movable or mobile containers comprises a refrigerant compressor 8, a condenser 7, a throttling means 10, and an evaporator 6 serially connected in a. closed refrigerant loop; a fan 12 positioned to circulate air in the container and a fan 15 positioned to circulate air over the condenser 7, the fan 12 operating continuously whether an engine power source or a standing-still motor source is in operation, except during those periods when defrosting is necessary. The internal combustion engine 19 is connected to a jack shaft 20 by way of a centrifugal clutch 21 which is responsive to engine shaft speed. A sheave 28 on the input shaft 61 to compressor 8 is interconnected with a sheave 29 on a first electric motor 30 via V-belt 31. Evaporator fan shaft 13 is provided with a sheave 32 which is interconnected to sheave 33 on a second electric motor 34 via V-belt 35. Condenser fan shaft 16 and evaporator fan shaft 13 are engaged upon energization of electro-magnetic fan clutch 18. A control system 37 for use in the operation of the mobile refrigeration unit includes a selector switch shown as making contact with terminal E rendering the system ready for engine drive operation. As the engine is started and brought to speed, clutch 21 engages thereby placing engine 19 in driving relation with jack shaft 20 which in turn is drivingly connected to compressor 8 and fan shaft 16, and fan shaft 13 by way of clutch 18. A thermostat 36 determines whether reverse valve 11 is brought into operation or not. When a defrost switch 45 is energized, contacts 41 are opened thereby deenergizing clutch 18 so that fan 12 will not circulate warm air from the evaporator 6. When engine 19 has been turned off, switch 39 is placed in position bridging contact M, thereby connecting the second electric motor 34 to alternating current power source 59 thus causing fan 12 to be driven by motor 34. Motor 34 does not drive shaft 16 as clutch 18 is disengaged. Should the temperature rise above a certain desired value, thermostat 36 brings into operation first motor 30 to drive the compressor 8 and through jack shaft 20 fan 15. Should the temperature fall, the contacts 44 and 57 of the thermostat close, thereby energizing reversing valve 11. If the system requires defrosting while on this stand-still motor cooling cycle, switch 45 is closed as before.

Abstract: 1306363 Photographic aurous iodide emulsions KODAK Ltd 7 May 1970 [8 May 1969] 23550/69 Heading G2C [Also in Division C1] A light sensitive photographic emulsion comprises a dispersion of light-sensitive aurous iodide grains in a hydrophilic colloid, preferably gelatin. The emulsion may be prepared by mixing aqueous solutions of sodium auric chloride and potassium iodide in the presence of the colloid or by adding the colloid after mixing the solutions as a solution to the newly formed aurous iodide. The precipitation of aurous iodide may be carried out in the presence of a mild reducing agent e.g. sodium sulphite. The exposed material may be developed with a silver halide developer solution or an aqueous hypophosphrous acid solution followed by washing. No separate fixation step is necessary since the developer solutions act as a monobath due to the solubility of aurous iodide therein. The imagewise exposed and developed material may be contacted with a nucleated receiving sheet immediately after developer application to form a transfer image on the receiving sheet. The nucleated receiving sheet may be a conventional silver salt diffusion transfer receiving sheet.
