Patent GB-1157621-A (GB)
Title: Improvements in or relating to Laminated Sheets.
Inventor: MORRIS DAVID RICHARD
IPC: B32B5/28
Filed: 1965-05-25
Abstract: 1,157,621. Laminates; moulding reinforced articles. ENGLISH ELECTRIC CO. Ltd. 18 Aug., 1966 [25 May, 1965], No. 22188/65. Headings B5A and B5N. A process for producing a laminated sheet includes the steps of impregnating a mat, cloth or filaments of glass fibre 14 with a thermosetting plastics material 15, passing the impregnated mat, cloth or filaments through a heated die 16 and bonding a sheet of thermoplastic material 11 to the resulting reinforced solidified thermosetting plastics material by the application of pressure either simultaneously, by means of the die 16, or subsequently by means of rollers: see the figure accompanying the Complete Specification (not shown). The thermosetting resin 15 may be a polyester resin. The thermoplastic sheet 11 is preferably polypropylene but may be polyvinyl chloride or polythene. The sheet 11 may be first bonded to a sheet of woven material 12 of glass fibres and polypropylene fibres by heat and pressure applied by rollers 13. Alternatively, the sheet 11 may be bonded directly to the cured impregnated fibres 14 after passage of the latter through the die 16, and after application of adhesive to a surface of the sheet 11, by means of pressure rollers. The adhesive may be an epoxy resin contact adhesive. The heated die 16 may have cooled inlet and outlet portions to prevent premature curing of the thermosetting resin, and the die opening, instead of being flat, may be of channel or other shape to produce a product of corresponding section.

Title: Differential gearing
IPC: F16D41/00
Filed: 1963-06-05
Abstract: 1,049,652. Differential gearing; positive clutches. J. ROTTER. June 5, 1963 [June 7, 1962], No. 22277/63. Headings F2C and F2D. In a differential gear, relative rotation of the driven shafts causes disengagement of one shaft. Two clutch plates 12 splined to driven shafts 5, 6 are urged by springs 13 to engage integral dogs 2 with grooves 10 in a clutch ring 1 rigid with a driving bevel gear 7. When one shaft 5, rotates faster than the other shaft 6 the dovetail dog 2 rigid with the faster shaft is released from the undercut groove 11 in the clutch ring 1 and is moved axially for disengagement by a roller 3, rigid with one clutch plate, co-operating with a cam surface 4 rigid with the other clutch plate; the other dog 2 being held by the undercut to prevent disengagement of the slower shaft. Slight driving torque is provided between the shafts by spring-loaded friction discs 14 to assist return of the dogs to the engaged condition. The undercutting of the grooves may be omitted and the roller replaced by a sliding element.

Title: Conveying arrangement
IPC: B65G47/49
Filed: 1974-05-20
Abstract: 1427308 Discharging articles and different positions along a conveyer belt SANDCO Ltd 20 May 1974 22355/74 Heading B8A Articles, e.g. boxes 16 on a steel conveyer belt 10, are discharged at a selected station 17, 18, or 19, or at the end of the belt, by an operator pressing the appropriate selector key 51. This causes a magnetic spot to be induced in the belt by one of a series of magnetizing heads 40, 41, 42, or 43. The charging circuit of the latter includes a positive-temperature-coefficient resistance means. Prior to passing over the heads, the belt passes over a demagnetizing device 45. If for example an article 16 is to be discharged at the station 18, a spot is induced by the head 42 and when the article reaches the station 18, the spot is detected by a sensing head 31 which causes a member 23 to be moved from an inoperative to an article discharging position. In another embodiment (Figs. 2, 4, and 6), there are eight lanes of articles and each magnetizing head is arranged on a respective plug-in circuit board 72. Also arranged on each circuit board 72 is a demagnetizing head 63. Each magnetizing head comprises a U-shaped iron core 77  having a pair of windings 88 and 89 (Fig. 6) for inducing a magnetization of North polarity, and a pair of windings 90 and 91 for inducing a magnetization of South polarity. Each pair of windings is energized by a pulse of current via a transistor circuit 98 and associated AND gate 106, from a condenser 92. If the transistor circuits or the condenser 92 fail, a light 96 functions both as a visual warning and the positive temperature coefficient resistance.
Patent GB-410118-A (GB)
Title: Manufacture of organic esters of cellulose and its derivatives
IPC: C08B3/12
Filed: 1932-08-10
Abstract: Cellulose phthalate is prepared by treating undissolved cellulose with phthalic anhydride in presence of an organic tertiary base and continuing the phthalylation until a dope is formed; one carboxyl group esterifying the cellulose, and the other being combined with the organic base, from which it can later be freed by treating the product with an acid.  Cellulose modified or pretreated in any way so as to increase its reactivity, regenerated cellulose or a cellulose ester or ether containing free hydroxyl, for example, a cellulose acetate or a cellulose ethyl ether may be used as starting material. Pyridine, quinoline, or other saltforming bases of the same group, or bases such as the dialkylanilines, for example, dimethyl aniline, the hexalhydro-dialkylanilines, dimethyl n - hexylamine are suitable organic bases.  A solvent such as benzene, tetrachloroethane, or ethylene chloride may be added to the reaction bath.  The reaction temperature is preferably below 95 DEG  C.  When the required degree of esterification is attained, the reaction mass is precipitated in a non-solvent for the ester.  The products obtained are generally soluble in water containing a small amount of pyridine, in pyridine-benzene pyridine-tetrachlorethane, pyridine-ethylene chloride and similar mixtures, and in other inert organic solvents. From solutions of the esters in suitable solvents transparent sheets or skins may be formed, plasticisers such as an alkyl phthalate, triphenyl or tricresyl phosphate, a p - alkyloxalkyl phthalate, or tributyl phosphate.  The esters may also be used in adhesives, for laminated glass, lacquers, artificial silk, and moulded products, either alone or mixed with a plasticiser and other compatible addition products.  Examples are given.  U.S.A. Specification 1,704,306 is referred to.ALSO:Cellulose phthalates are employed in the manufacture of moulded products &c.  Phthalic acid derivatives of cellulose esters such as the acetate or of cellulose ethers such as the ethyl ether which still contain esterifiable hydroxyl groups are included. These esters are generally soluble in pyridine and in mixtures of pyridine with suitable organic solvents; from the solutions transparent sheets or skins may be formed, plasticisers such as an alkyl phthalate, triphenyl or tricresyl phosphate, a b -alkyloxyalkyl phtholate, or tributyl phosphate being added. When used in the manufacture of moulded products, plasticisers and other compatible addition products may or may not be added. U.S.A. Specification 1,704,306 is referred to.

Abstract: 930,795. Fluid-pressure servomotor systems. P. FIORENTINI. July 4, 1960 [Dec. 2, 1959], No. 23245/60. Class 135. In a pressure regulating valve, a diaphragm 14 has a lost-motion connection with a valve spindle 2 and a rigid connection with a pair of resilient control valves 22, 28 actuated in response to outlet pressure variations to keep the pressure in a balancing chamber 8 proportional to inlet pressure. Gas from an inlet 5 flows through a filter 12 and a closure member 1 on the stem 2 to an outlet 6 having a conduit communicating with the space below the diaphragm 14. A rise in outlet pressure lifts the diaphragm to open the valve 22 and allow gas from the inlet to flow into the chamber 8 through passages 19 and 17 while a fall in outlet pressure opens the valve 28 to vent the chamber through the passages 17 and a bore 29 in a rigid member 27 between the valves. This member is rigidly connected by a pin 27 to a pair of sleeves 15, 24 having the diaphragm 14 clamped between them and moves relatively to the spindle 2 which carries a flanged sleeve 23 limiting the lost motion. Metal sealing bellows 32, 33 are provided.

A ball float drops to allow water to enter boiler 34, but on falling below a lower limit, it operates a switch to de-energise the heaters. The water supply is also connected to spray nozzles 46 controlled by handle 45. A flap 26 covering a neck recess hinges back to form a head rest. An arrangement for supplying air of controllable temperature to the cabinet is also described.
