Patent GB-681861-A (GB)
Abstract: 681,861. Cash registers. ANKER-WERKE AKT.-GES. Dec. 20, 1949 [Oct. 1, 1948], No. 32655/49. Class 106 (i). A cash register or accounting machine has means in the height range of the item-setting means for printing on an inserted bill, means, at about the same height, for printing on a record strip and means, arranged beneath the first two printing means, for printing on a voucher to be issued. The type wheels 4-8 each carry three sets of type and are mounted in a housing 10. The wheels 4-6 are secured to concentric tubes 9 which are set by the itemsetting means (not described) to cause the amount, clerk's symbol and transaction symbol respectively to be printed. Type wheels 7 and 8 are rotatable on a cylindrical bearing 13 secured in the housing 10. The wheels 7 print a consecutive number and are operated by a counting-mechanism (not described). The four wheels 8 are internally toothed and mesh with gears 17-20 which project through apertures in the bearing 13 and are hand-set, by rotation of a key engageable on respective shafts 27 carrying the gears 17-20, to print the date. These shafts carry indicator discs, e.g. 21, 23, visible through windows 25 in a cover 26, round which passes an automatically-advanced ink-ribbon. The bill is inserted through an aperture 61 in the machine casing and passes behind the type wheels and against a stop 30. A printing hammer 28 impresses the bill against the type and, if desired, may operate twice, in which case the stop 30 is raised between the two printing operations. The guide 60 for the bill may be extended to the rear wall of the machine to receive a strip instead of a bill. The record-strip passes from a roll 70 round a guide 32 to a roll 71, which is advanced during each operation by a pawl on an arm 90 rocked by a roller in a cam 88 on the main shaft. The cam 88 operates a link 69 to cause a hammer 31 to take an impression. The record strip is visible through an opening 73 in the casing and autographic entries may be made thereon. The voucher strip is fed from a roll 81 between a hammer 33 and the type wheels, past a cylindrical cutter 34 and between guides 35 and 36. The cutter and hammer are cam-controlled to operate one or more times during each operation and the cutter may be such as to perforate tear lines between successive prints. The severed voucher drops on to a pair of spring belts 37 which are driven to throw the voucher forwardly on to a plate 55 at the front of the machine. To this end, the shaft carrying pulleys 38 for the belts also carries a pinion 40 which is engaged by a rack 41 after it has been moved forwardly by a lever 47 and depressed by the engagement of a lug 42 thereon with a spring guide 43. The lever 47 is operated by a roller 50 in a cam rotated from the main shaft and, as the roller leaves the lever 47, a spring 49 rapidly restores the rack 41 to operate the belts 37. A flywheel 54 geared to the pulleys 38 causes the belts to continue to operate after the machine cycle has been completed.

Abstract: 744,944. Sliding clasp fasteners. SUSS, O. Aug. 26, 1953, No. 23518/53. Class 44. In a sliding clasp fastener having inverse, handed inter-locking elements comprising helicoidal spring coils, the coil or coils of the one hand are identical in pitch to, but of different diameter from, the coil or coils of the other hand, the pitch being equal to or wider than the thickness of the wires constituting the coils when the elements are interlocked. As shown, single coils 1 and 2 having coil diameters D and d respectively are sewn to tapes 1<SP>1</SP> and 21 and are of identical pitch b and wire thickness s, but the helicoidal spaces between the coils are wider than the thickness s. In other arrangements, Figs. 2 to 5 (not shown), both elements in one arrangement consist of a pair of identical coils, the diameters of the identical coils of one pair being greater than that of the other pair, and in the other arrangement both elements consist of a pair of coils, the coils of each pair having different diameters. In all forms the coils may be of metal or synthetic plastic and the wires of the coils may be of different thicknesses or profiles.

Title: Valve structure
IPC: B60C23/00
Filed: 1979-09-12
Abstract: A valve structure for inter-connecting the tyres of a set of dual tyres to equalize the pressures therein including a casing (10) having therein a cylinder (14) at one end of which is a valve seat. A piston (20) carrying a valve closure element (28) is spring urged towards said seat and the interiors of the tyres communicate with the chamber 14 via passages (18, 30) so that the air pressures therein may be used to hold said element away from the seat. Should either tyre deflate to below a predetermined pressure, the spring urges said element (28) against said seat to isolate the tyres one from the other. A warning device triggered by movement of the piston to close the valve warns the driver that he has an under inflated tyre. A semicylindrical groove (96) in the casing (10) and a bore (98) co-axial with the groove serve to receive a tyre inlet connection (104), there being a valve opening element (116) in the bore (98). <IMAGE>

Abstract: A device for remote control of a hydraulic crane which includes a hydraulic pump, a plurality of fluid actuators for hoisting a boom tilting cylinder, a boom telescopic cylinder, a hoisting motor and a turning motor or the like connected in parallel via oil passages to hydraulic oil supply and exhaust circuits connected to a hydraulic oil tank, operation selecting solenoid valves connected to the oil passage, a proportional solenoid relief valve provided in the oil passage for bypassing the exhaust side of the pump to the tank for controlling the exhaust side hydraulic oil from the hydraulic pump in a crane body and automotive body side, respectively, operation selecting switches for the respective operation selecting solenoids and a potentiometer for controlling the proportional solenoid relief valve in an operation terminal unit wherein the solenoids of the solenoid valves are electrically connected via cables to the switches and potentiometer. In order to control the crane hoisting speed, the conventional relief valve heretofore provided at the exhaust side of the hydraulic pump as a hydraulic oil source is constructed of the proportional solenoid relief valve instead of the conventional flow control valve to thereby control the hydraulic oil and accordingly the operating oil pressure at the exhaust side of the pump. This controls the operating speed of the fluid actuator for hoisting to thereby enable an economical and smooth hoisting operation as well as its remote speed control.
