Abstract: 868,181. Animal-spraying. BIGGINS, W. H., HIGGINS, K. M., and HIGGINS, B. L. Sept. 30, 1959 [Oct. 1, 1958 ; Nov. 24, 1958], No. 33125/59. Class 5(1). Animals are sprayed in a circular pen A fitted with a rotary, overhead spray which comprises nozzles 4 and 4a at the ends of pipes 1 and 1a extending from a header 2 which is rotatably mounted on a delivery pipe 3. The nozzle 4a, together with the attached control arm 7, is rotatable in a plane perpendicular to the axis of the tube 1a, and by positioning the nozzle so that the jet issuing therefrom is inclined to the vertical, the face of the jet may be utilized to rotate the spray unit. As the unit rotates, the arm 7 contacts an abutment 9 on a support member 8, and is thus moved to alter the position of the nozzle 4a and thereby reverse the direction of rotation of the spray unit, the movement of the arm 7 being limited by a bracket 10. Movement of the arm 7 is assisted by a tumbler weight 13 pivoted at the end of the arm.

Abstract: 865,830. Fluid-pressure servomotor control systems. NORMALAIR Ltd. Sep t . 29, 1959 [Oct. 17, 1958], No. 33142/58. Class 135. [Also in Groups VI and XXI] A by-pass valve 13 is incorporated in an aircraft respiratory circuit and permits rapid inflation of a flying suit 11 in an emergency. The valve 13 is supplied by a branch pipe 12 from the main supply 1 and comprises a casing 17, an oxygen inlet 18 and an outlet 19. If a sudden drop in pressure occurs in the line 14 in Fig. 1 then the capsule 26 expands, turns the lever 30 against the spring 32 and allows the pressure of oxygen in the chamber 20 to open the valve 23 so that the oxygen enters the chamber 21 and acts on a diaphragm 25 which turns the lever 37 and opens a main valve 24 against a spring 44. Oxygen then passes directly from the inlet 18 to the outlet 19 and hence to the suit. Oxygen is exhausted from the chamber 21 past an adjustable bleed screw 29. Specification 785,371 is referred to.

Patent GB-1072794-A (GB)
Title: Method of recovering formic acid
IPC: C07C51/487
Filed: 1964-08-19
Abstract: Aqueous formic acid is obtained from the waste liquor from the production of a polyol by the aldol condensation using formaldehyde in the presence of an alkali metal hydroxide, which liquor contains the alkali metal formate, together with residual polyol, organic impurities and water, by concentrating the liquor, liberating formic acid from at least 75% by weight of the alkali metal formate by treatment with a non-oxidizing acid forming an alkali metal salt which precipitates from the liquor, separating the precipitated alkali metal salt and distilling the remaining liquor under reduced pressure to recover aqueous formic acid as distillate, additional water being introduced during the distillation to minimize esterification of the formic acid.  The distillate may be further distilled under atmospheric pressure to remove water overhead and yield the maximum boiling-point azeotrope of formic acid and water.

Abstract: 967,324. Laminates and laminating. ST. REGIS PAPER CO. Oct. 5, 1960 [Oct. 22, 1959], No. 34181/60. Heading B5N. [Also in Divisions D2 and F2] Laminates comprising plies of resin-bonded fibrous sheet material surfaced with polytetrafluoroethylene (P.T.F.E.) are made by impregnating fibrous sheets, e.g. of paper, cotton or other cloth, or glass fibres, with a thermoset resin such as phenol- or cresol-formaldehyde resin in the B stage, superposing a layer of P.T.F.E. the contacting surface of which has been activated by treatment with an alkali or alkaline earth metal, e.g. a solution of sodium in liquid ammonia, and bonding the layers with heat and pressure and without additional adhesive. A suction box cover for paper - making machines, Fig. 3, comprises a layer 28 of P.T.F.E. bonded as above in a platen press to a base 29 of fibrous plies, both components being perforated as at 30. The press may have semi-cylindrical pressing members and may produce an imperforate semi-cylindrical laminate having the P.T.F.E. layer on the inner side and usable as a bearing member. The P.T.F.E. layer may contain carbon or glass fibres. In Fig. 4 a mandrel 30 has wrapped around it a layer 40 of surfaceactivated P.T.F.E. of length slightly less than the mandrel circumference. The free end of a resin-impregnated web 34 is wrapped over the layer 40, a projecting end 41 being then cut off. The web 34 is then drawn from a roll 35, by rotation of the mandrel, and is wound over and pressed on the layer 40 by pressure rolls 31, 32, 33. The completed laminate is removed from the mandrel and baked in an oven for 2-8 hours at 300-330‹ F.; it may then be subdivided into bearing members. Specification 793,731 is referred to.
