Title: A safety cut-off device for hydraulic braking systems
IPC: B60T11/32
Filed: 1966-09-22
Abstract: 1,133,356. Hydraulic brakes; brake indicators. ALFRED TEVES MASCHINEN - UND ARMATURENFABRIK K.G. 22 Sept., 1966 [3 March, 1966], No. 42341/66. Headings F2E and F2F. [Also in Division H1] In a safety cut-off device for hydraulic brakes, a valve device is inserted between the master cylinder 10 and the wheel brake cylinders 35, the valve device comprising two casing halves 21, 22 which are located together and separated by a diaphragm 23. In operation, when the brakes are applied fluid under pressure is applied from the master cylinder 10 via conduit 33 into chamber 28 such that an increase in pressure in the chamber 28 results in a distortion of the diaphragm 23 to close a non-return valve 30, the pressure medium in the chamber 27 being forced through a screen 26, conduit 34 to the wheel brake cylinder 35. Should a leak develop in the line leading to the wheel brake cylinder the resilient partition 23 is distorted and bears against the chamber wall 29 to operate a contactor 36 of an electric warning system to automatically switch on a warning lamp 37. At the same time fluid is prevented from passing along the broken conduit 34. Each of the two casing halves 21, 22 are formed with bleed valves 39 and 40. Adjustment of the screw 32 determines the quantity of pressure medium which may be lost during one operation of the brake and compensated for by the non-return valve 30.

Title: Transmission comprising a hydrostatic coupling and a hydrodynamic torque converter in series
IPC: F16D31/04
Filed: 1960-12-09
Abstract: 969,964. Hydraulic transmissions ; friction clutches. SVENSKA ROTOR MASKINER A.B. Dec. 9, 1960 [Dec. 19, 1959], No. 42436/60. Heading F2C. An hydraulic transmission comprises an hydrostatic coupling of the pump type provided with low- and high-pressure chambers 66, 68 and located in series with an hydrodynamic torque converter 34, and a selectively-operable valve 28 adapted to connect the high-pressure chamber 68 of the coupling with an outlet 168, the low-pressure chamber having at least one inlet opening 84 of a restricted area. The operation of the valve permits slip to occur in the coupling thereby permitting gearing associated with the transmission when in a vehicle to be moved from forward to reverse drive or vice versa. The coupling comprises a gear 36 which is secured to an input shaft 10 and engages gears 54, in turn engaging further gears 58, the gears 54, 58 being mounted in a casing 38, which is secured to the pump 138 of the converter, and constituting pumps for passing fluid from the lowto the high-pressure chambers. The low-pressure chambers are supplied with fluid from an inlet 154 between reaction and turbine shafts 154, 148 respectively connected to reaction blades 144 and turbine blades 140, 142, openings 155 leading to the working circuit of the converter, bearings 170, a chamber 86 housing a friction clutch 32 between the pump and turbine members of the converter, the restricted inlet 84, and a passage 80, fluid in excess of requirements passing through ports 88 to a passage 166 and an outlet 168. The high-pressure chambers are connected by passages 92, 94 and 104 to the valve 28 which when in its left-hand position wherein it is urged by a spring 128, disconnects the passage 104 from the outlet. Fluid pressure from a pump can be supplied through passages 25, 122, 124 to the left-hand side of a piston 116 secured to the valve to move the latter against the spring to connect the high-pressure chambers to the outlet thereby permitting slip in the coupling. Valves 26 are provided to limit the maximum pressure in the high-pressure chambers. The clutch 32 is engaged by a piston 158 movable by fluid pressure supplied to a chamber 115 from the passage 168 which is then connected to a high-pressure source by a main valve which may also control the supply of fluid to the piston 116 of the valve 28. Specification 854,007 is referred to.

Abstract: 974,784. Sewing machines. MITE CORPORATION. Oct. 28, 1963, No. 42455/63. Heading D1G. A sewing machine attachment for buttonhole sewing comprises a base plate 10 formed at its respective longitudinal sides with vertical flanges 11,12 and at its front edge with a vertical flange 14 carrying an adapter 13 for attachment to the sewing machine presser bar, and a work-feeding blade 15 which pivotally carries a work-feeding foot 17, is longitudinally slidable on lugs 20 depending from plate 10, and is formed adjacent one edge with a longitudinal slot 60 slidably and pivotally engaging a vertical pin 56 rigid with plate 10. Pin 56 is slidable in a longitudinal slot 57 formed in plate 10, and is fixable in adjusted position therein by a finger piece 62 which passes through a slot in flange 12, a lug 67 being selectively engageable with spaced notches formed in said slot. Blade 15 is connected at its rear end by a vertical wall 21 to an upper horizontal portion 23 formed with an aperture removably receiving a buttonhole template 23 comprising a continuous rack 24 and a parallel continuous groove 25. Template 23 is held in position by a wire spring 26 pivoted at 27 to flange 12 and releasably engageable with a hook portion 28 of flange 11. A vertical shaft 30 journalled in plate 10 has rigid therewith a pinion 29 and a ratchet wheel 34. Pinion 29 engages rack 24, and the reduced upper end of shaft 30 engages groove 25. A plate 35, pivoted on shaft 30, carries a pivoted pawl 37 biased into engagement with the ratchet wheel by a spring 38. A blade 49, which is formed with a longitudinal slot slidably engaging a pin 51 rigid with flange 11, is formed at one end with a lug 54 engaged between a pair of lugs 39 on plate 35, and is pivoted at its other end, at 48, to a plate 46 pivoted on a pin 43 carried by a vertical lug 43a rigid with plate 10. A finger piece 52, rigid with blade 49, provides for manual operation of the attachment. An arm 42, also pivoted on pin 43, is formed at its free end with an elongated slot engageable with the needle clamp of a zig-zag sewing machine, and is drivably connected to plate 46 by a lost-motion coupling. To this end, arm 42 is formed with an arcuate slot 42a concentric with pin 43. A screwed stud 55, passing through slot 42a, has an enlarged head engaging the inner surface of arm 42, and carries a nut 47a which engages the outer surface of arm 42 to secure stud 55 in adjusted position in slot 42a. Plate 46 is formed with an arcuate slot 45 which receives the enlarged head of stud 55. The adjusted portion of the latter thereby determines the length of the stroke imparted to blade 49.

Abstract: 1,183,479. Cutting by fusion. D. A. POLLOCK. 25 Sept., 1968 [26 Sept., 1967], No. 43821/67. Heading B3V. [Also in Divisions B6 and G3] A method of manufacturing a strip-form printing plate, for printing along a base-tape a variable width recording of information initially in the form of electric signals, comprises making an intermediate recording which is read at a reduced speed to supply signals controlling a continuous forming apparatus, whereby the required plate is produced at the lower speed. As shown, Fig. 1, a magnetic tape 1, bearing a conventional recording of music, is read by consecutive play-back head 3, 4 of a tape-deck 2. The output of head 4 is used to deflect a mirror galvanometer assembly 19 of a photorecorder 5 and the output of the head 3, through a time-delay device 20, produces a D.C. bias which is used for ground-noise reduction. The movement of the galvanometer assembly 19 produces an intermediate recording by the bilateral illumination of a film 6. The magnetic tape recording can be replaced by a disc and the pick-up heads then comprise styluses running one after the other in the recording groove. The film 6 is read in a unit 7 at the speed required for optimum operation of an electron beam milling unit 11 which produces a master tape 12, 13. In the unit 7 the film 6 is passed in front of a lamp 9 and the light passing through a slot 8 falls on a gas-filled photo-tube 10 which produces control signals for the milling unit 11. Alternatively, the intermediate recording is made on a disc and read by a stylus which deflects a mirror-and-photocell assembly on a tracking arm by which the control signals are developed. The milling-unit 11 generates electron or laser beams which are oscillated across the tape from the edge at a frequency in the range of 10-12 kHz. The milling beam is limited heatresisting blocks and particles detached by the milling beam are removed by a suction nozzle or a statically charged electrode. It is stated that, alternatively, material can be removed by a cathode-sputtering process. Additional copies of the tape may be made from wax moulds produced by a continuous impression technique from the master tape. The material of the master tape can be copper or a colloidably-provided metal on a supporting base.
