Title: Insect-repellant composition and process
IPC: A01N37/36
Filed: 1962-07-24
Abstract: An example described a soap comprising olive oil which has been saponified with sodium hydroxide, and methyl 2-hydroxy-4-phenylbutyrate as an insect repellent ingredient.ALSO:Insect repellant compositions comprise as active ingredient a compound of the formula R1CH2CH(OH)COR2 wherein R1 is hydrogen, benzyl, monochlorobenzyl or monomethyl benzyl; and when R1 is hydrogen, R2 is dialkylamino or dialkenylamino, each alkyl and alkenyl group containing up to 8 carbon atoms; and when R1 is benzyl, monochlorobenzyl or monomethyl benzyl, R2 is cyclohexyloxy, alkoxy, alkenyloxy, alkylamino, alkenylamino, alkylalkenyl-amino, dialkylamino or dialkenylamino, each alkyl and alkenyl group containing up to 8 carbon atoms; together with an extending agent. The compositions may be used in the form of solutions, suspensions, emulsions, aerosols, dusts, powders, ointments and soaps with the usual extending agents.  For emulsions and suspensions, surface-active agents may also be included, e.g. soaps, Turkey-red oil, fatty alcohol sulphonates, fatty acid ester, quaternary ammonium compounds and condensation products of ethylene or propylene oxide with alcohols.  Other insect repellants or insecticides, e.g. DDT, may additionally be present. In some of the examples, solutions of various of the active ingredients were applied to cotton bunting cloths in order to test the effectiveness of the insect repellants.

Title: Apparatus for synchronizing data read from parallel data tracks on a record medium
IPC: G11B20/20
Filed: 1962-07-24
Abstract: 935,893. Magnetic tape data storage. NATIONAL CASH REGISTER CO. July 24, 1962 [Oct. 23, 1961], No. 28394/62. Class 106 (1). In a system for compensating for misalignment in data read from magnetic tape each bit channel is provided with an individual variable delay. As described, magnetic tape 10 has data recorded thereon in six parallel channels, the misalignment due to tape skewness and to " gap scatter " of the recording heads (not shown) being indicated by arrows 13, 15, and the " gap scatter " of the read heads 12 being indicated by their relative misalignment. A block of data on the tape 10 is preceded by a mark 24 in a marker track MT1. The first two block characters are 111111 followed by 000000 which are reproduced in misaligned fashion as shown in Fig. 2A. In operation, reception of the marker pulse 24 triggers a mono-stable circuit MS1, thereby (1) resetting flip-flops F1-F6, (2) setting a flip-flop G1 to enable gates 18, and (3) resetting the delay devices D1-D6. The preliminary " 1 " bits in each track cause the associated flip-flops F1-F6 to be set, thereby producing signals S 1 -S 6  applied to the delay devices D1-D6, these signals being terminated by the resetting of the flip-flop G1 when all the preliminary " 1 " bits have been reproduced (at time t 2 ). The delay devices D1-D6 are thus conditioned to delay the signals in the associated channels by an amount dependent on the duration of the corresponding signals S 1 -S 6 , the aligned bits being passed via gates 20 to a data processor 22, where each character can be applied to an " or " to produce a clock pulse. Alternatively, a separate clock pulse can be provided on the tape 10. The delay devices D1-D6 are as described in Specification 907,492 [Groups XXXIX, XL (c)].

Title: Fluid pressure system
Inventor: SHUTT PAUL BENJAMIN
IPC: F15B13/01
Filed: 1958-09-05
Abstract: 837,531. Tractor power-lift systems. BENDIX AVIATION CORPORATION. Sept. 5, 1958, No. 28621/58. Class 79(1) [Also in Group XXIX] In a hydraulic lift system, e.g. for raising and supporting loaders on a tractor, a lift cylinder 12 is supplied from a pump 10 through a selector valve which enables the load to be lifted, to descend freely, and to be arrested gradually whereby it can be locked hydraulically in any position of descent. As shown, a selector slide valve 50 which is spring biased towards a neutral position as shown and supplies the cylinder 12 through a ball valve 34, has three annular chambers 98, 100 and 102 and co-operates on one side with pump pressure and return ports 60, 56, respectively, and on the other side with motor and exhaust ports 66, 72 respectively. The ball valve 34 is biased towards the closed position and can be forced off its seat by an actuating piston 104. The underside of this piston can be placed in communication with the pressure port 60 or the exhaust port 72 or can be isolated by the selector valve, and there is a restriction 106 connecting the underside of the piston to the space beneath the ball valve 34. On raising the slide valve 50 from. the neutral position, pump pressure is supplied beneath the ball valve 34, and thence to the lift cylinder, through chamber 100 and port 66, the underside of the actuating piston 104 being simultaneously exhausted. Depression of the slide valve below the neutral position places ball valve 34 in communication with the return port 56 via chamber 98 and communicates the underside of piston 104 to the pressure port 60 via chamber 100, so that the ball valve is forced off its seat and the load is allowed to descend freely. Movement of slide valve 50 back to the neutral position during this descent interposes a flow restriction 108 in the slide valve between the motor port 66 and the return port 56 and also isolates the space. beneath the actuating piston 104. Flow out of this space through the restriction 106 allows the ball valve to close slowly until the load is arrested. A further restriction to return flow from the cylinder 12, when the ball valve is held off its seat by piston 104 and the slide 50 is first moved to its neutral position, is constituted by the clearance between the actuating end 30 of piston 104 and the ball valve seat 20; the clearance may be formed by an enlargement on the tip of the end 30 so that there is substantially no flow restriction when the ball is held in its fully released position.

Abstract: 757,103. Embossing thermoplastic sheet material. BRITISH CELANESE, Ltd. Oct. 20, 1954 [Oct. 22, 1953], No. 29233/53. Class 100 (2). [Also in Groups V and XVII] A method of attaching an article or articles, e.g. buttons, to a thermoplastic sheet comprises supporting the or each article so as to expose the greater part but not all of its surface, clamping the sheet by its edges so that it faces the article, heating the sheet by radiant heat to render it plastic, causing gaseous (preferably atmospheric) pressure to act suddenly on the surface of the sheet remote from the article and force the sheet into close overall contact with the exposed surface of the article, so forming in the sheet a pocket which partially encloses the article and has a mouth of smaller area than the maximum cross-sectional area of the article in a plane parallel to the sheet, and thereafter cooling the sheet. Fig. 1 shows one of a number of buttons 10 spaced apart on a porous base sheet 11 which is supported on a perforated partition 12 in a vacuum box across the mouth of which is clamped a thermoplastic sheet 13. After the sheet has been heated, a vacuum is created below the partition to suck the sheet around the articles and into contact with the base sheet, as shown in Fig. 2, and after the sheet has cooled it is trimmed at the edges and stripped from the base sheet. The sheet 11 may be made of paper, knitted or woven fabrics, felt, glass or wire fabrics or perforated metal foil, the surface characteristics of the sheet being imparted to the portions of the sheet 13 surrounding the pockets. Alternatively, it may be non-porous and provided with surface channels which allow the withdrawal of air, in which case it does not extend to the edges of the partition. Non-porous materials which may be used are sandpaper, hammered glass or scored sheet metal. The base sheet may be given a thin coating of a silicone stripping agent or impregnated with polytetrafluoroethylene to facilitate removal of the sheet 13, and may be ridged to produce lines of weakness in the sheet 13 between the articles so that individual articles may be torn from the sheet.
