Patent GB-534326-A (GB)
Abstract: 534,326. Fatty oil compositions. AMERICAN CYANAMID CO. Jan. 27, 1940, No. 1702. Convention date, Feb. 25, 1939. [Class 91] An oil composition suitable for use in paints, varnishes and enamels is prepared by mixing an incompletely polymerized alkylated aminotriazine-aldehyde condensation product with a triglyceride oil and heating the mixture until a uniform blend is obtained. It is stated that the film forming characteristics of triglyceride oils such as non-drying, semi-drying and drying oils are greatly increased by this treatment. In examples (1) Hexamethylol melamine is heated in butanol solution with phosphoric acid and the .water continuously distilled off. The butanol solution so obtained is heated with linseed oil for 20 minutes to give an oil which will take to a hard clear film. (2) Melamine is heated with formaldehyde solution which has been neutralised with caustic soda and a solution of butanol .acidified with phosphoric acid added and the water removed as before. The product so obtained is condensed with soya bean oil. (3) 2:4-Diamino-1:3:5-triazine is condensed with formaldehyde as above but using cyclo-hexanol in place of butanol, and the product condensed with soya bean oil. In place of soya bean oil there may be used oiticica oil. (4) Ammeline is condensed with formaldehyde as above, polymerized with butanol containing phosphoric acid, and the product condensed with castor oil. (5) The butylated melamine-formaldehyde solution of example (1) is condensed with cottonseed oil. (6) Kettle boiled linseed oil is substituted for cottonseed oil in example (5).

Filed: 1968-11-21
Abstract: 1,248,604. Percussive tools. CANRON Ltd. CANRON LIMITEE. 21 Nov., 1968 [24 Nov., 1967], No. 55279/68. Heading B4C. [Also in Division B3 and F1] An hydraulically operated rotary-percussive tool comprises a hammer piston 6 which reciprocates in a cylinder to impart blows via anvil 7 to a drill steel, the piston and cylinder together defining two variable volume chambers 19, 25 to which liquid, e.g. oil, under pressure is fed alternately via a distribution valve 60. The liquid is supplied by a constant velocity pump 77 and the supply circuit includes a pulsation damper 80 which enables the liquid being supplied to be maintained at a substantially constant pressure. A gas accumulator 10 imparts to the hammer piston on its working stroke energy stored during its return stroke. The drill steel is continuously rotated by an hydraulic motor 50 the exhaust of which passes via ports 16, 17 (Fig. 1a) to a supply tank and flows into a chamber ahead of the accumulator when the piston on its working stroke opens that chamber. In operation liquid is supplied to the chamber 19 and the piston is moved on its working stroke. When port E opens to the chamber 19 just before impact of the piston on the anvil 7, slide valve member 61 will move to the right to connect the chamber 25 with liquid supply, and the piston will, after impact, be moved on its return stroke. During the return stroke, port C opens to the chamber 52 and the slide valve member is returned to the position shown and liquid is supplied to the chamber 19 thus decelerating the piston. Towards the end of the return stroke the piston closes off the chamber ahead of the accumulator and further movement of the piston causes the accumulator to store energy. The piston is stopped by liquid trapped in a chamber 40. The energy stored and the liquid supplied to the chamber 19 force the piston on its working stroke. Lubrication liquid or fluid passes via ducts 47, 49, 43 and 45 to the working end of the drill steel. Fluid introduced via duct 41b into chamber 41a reduces or prevents recoil of the anvil.

Abstract: 1276552 Ultrasonic cleaning apparatus W R GRACE & CO 16 June 1969 [3 Oct 1968] 57054/70 Divided out of 1276551 Heading A4F [Also in Division G2] Apparatus for developing exposed photopolymerizable materials comprises a vessel containing developer consisting of a detergent solution, means for energizing the developer by ultrasonic energy, control means responsive to the concentration of the detergent solution and means actuated by said control means for delivering developer from a reservoir to the developing vessel to restore the concentration of developer to a predetermined value. The developed material may be subsequently washed in a water spray bath and dried in a curtain of moving air. As shown, the exposed material 62 in frame 60 is placed in a processing tank 10 containing detergent 12 and the material is moved up and down during development. Ultrasonic vibrations of 18-40 kilocycles per second are produced by transducers 14, 16 and 18. The concentration of the developer is monitored by electrode 52 which transmits this to control 48 via line 54. If concentration is too low, control 48 opens valve 40 allowing water into reservoir 42 containing detergent and causing detergent to flow through pipe 46 to tank 10. The liquid level may be maintained in the tank by water from pipe 32 controlled by valve 34 and any excess being removed by overflow 36. The temperature of the detergent is maintained at the desired degree by heater 56. After development, the material is transferred to tank 66 and washed by spraying with water from sprays 68 and on opposite sides of the material; the water may be heated. Air jets 76 and 78 may be provided to remove most of the water from the material. The washed material is placed in tank 84 where it is dried by heated air from jets 86 and 88 on opposite sides of the material. The material may be mounted in frame 96, Fig.4, which contains oppositely disposed L-shaped members 108 and 104 which fit into holes in the material and on to frame members 100. A handle 102 is fitted on to members 104 and is tensioned by spring 106.

Abstract: 1,243,349. Compression moulding. ESSO RESEARCH & ENG. CO. 6 Dec., 1968 [21 Dee., 1967], No. 58109/68. Heading B5A. In a method of baling particulate synthetic elastomer containing vaporizable and gasform material a confined body of such elastomer in particulate form is subjected to a reduced pressure to remove said material and the body is also subjected to mechanical pressure in the range 60 to 300 p.s.i. to form a body of higher density. The elastomer may be butyl rubber or polyisobutylene, and the reduced pressure may be between 1 and 10 inches of mercury absolute. The particulate material, before being subjected to reduced pressure, may be swept with a gas to remove vaporizable material. In the baler of Fig. 1, butyl rubber in particulate form is supplied to a cylindrical vessel 11 subjected to a reduced pressure via a conduit 14, and compressed by a piston 32 operated by pressure air supplied at 10. A cover 13 clamps a screen, not shown, in position, and is pivoted about a davit 25 and counterbalanced by a member 22 pivoted at 24. In the modification of Fig. 3 (not shown), for producing a rectangular bale, the upwardly driven piston is perforated and covered by a screen, and a reduced pressure is connected to the space below the piston. The baler top is closed by a horizontally slidable cover. Apparatus for continuous automatic operation, Figs. 4 and 5, includes loading, baling, and unloading stations 100, 101, 102, respectively, at each of which identical rectangular wall members 180, 108, 160 are located and supported for rotary movement about a vertical axis 106, so as to move from one station to another in turn. After a loading stage the assembly is moved around one station and the charge in the loaded wall, supported by a porous plate 109, is positioned between a perforated cover 114 and a lower assembly including a perforated plate 130. The charge is subjected to a sweep gas supplied via conduit 140, valve 138, passage 136 and plates 130 and 109; the gas is discharged via the cover 114, hollow shaft 116 and conduit 119. Pressure is then applied to the charge by moving the cover downwardly by a piston and cylinder 145 and forcing the plate 130 upwardly by a motor 134 and gearing 131, 132. Reduced pressure is applied via the valve 138, passage 136 and plate 130, and also via the hollow shaft 116 and conduit 119. On passing to the unloading station the bale is raised by an hydraulic motor 162 which lifts a plate 165 attached to the porous plate 161 by electromagnets 166; the bale is freed from the plate 161 by pressure air supplied at 168 and fed by an unloading belt 169 to a discharge conveyer 171.
