Filed: 1974-01-21
Abstract: 1503485 Rotary hand tools BUNKER RAMO CORP 21 Jan 1975 [21 Jan 1974] 02752/74 Heading B3N In a rotary handtool, such as a screwdriver, or one having a collet for receiving a variety of adjusting members as desired, an output member 12, rotatable relative to handle 10, is coupled to an actuating member, sleeve 11, rotatable on the handle, by means of reduction gearing comprising a pinion 14 which is restrained from rotating about its own axis but is gyrated eccentrically relatively to the handle by the actuating member within and in mesh with an internally toothed annulus 13 having more teeth than the pinion and being fixed coaxially to the output member. The pinion is restrained against rotation about its own axis by means of restraining member 15 having pegs 20 and slots 19 engaging with slots 22 in flanged sleeve 21 on the pinion and pegs 18 on boss 17 of the handle, the arrangement allowing gyration of the pinion which is located by the flange of sleeve 21 in an eccentric bore 24 in actuating member 11. Shaft 16, which is fixed to the output member, which may be of transparent plastics material, and passes through the other parts, to be held by a circlip 31 at the rear of the handle, holds the assembly together. The tool may be used as a normal screwdriver merely by rotating the handle but if the handle is held stationary and the knurled actuating sleeve is rotated the reduction gearing operates with a ratio equal to the difference in number of teeth on the pinion and annulus relative to the number of teeth on the annulus.

Title: Improvements in automatic vacuum railway-brakes
IPC: B60T8/18
Filed: 1921-01-26
Abstract: 181,049. Vacuum Brake Co., Ltd., and Walker, W. P. Jan. 26, 1921. Fluid-pressure; force-transmitting mechanism.-The leverage of brake mechanism for railway vehicles is automatically changed from the higher to the lower leverage suitable respectively for a loaded and unloaded vehicle, by the destruction of the vacuum or loss of air-pressure in the fluid-pressure brake system that gradually takes place when the vehicle is detached from the train. The high-leverage fulcrum k<2> of the brake lever k is arranged to slide in a slotted link n when bv means of a cam o the low-leverage fulcrum k<1> is held stationary and is thus effective. The fulcrum k<1> is carried by a block m which when the cam o is turned to the opposite position from that shown is free. to slide so as to render the high-leverage fulcrum k<2> effective. The cam shaft a has a crank to which is connected a rod c adapted to be engaged by a catch rod d, attached to a diaphragm e which encloses a chamber s connected by passage t<1> with the vacuum reservoir t of the vehicle. Assuming there to be no vacuum in the reservoir and the rod c to have been raised by the hand-lever g on the cam shaft the rod c is held by the tooth c<2> thereon in the high-leverage position under the action of the spring f on the bar d. Upon the establishment of the vacuum in the reservoir t and chamber s, the rod d moves to the right and the rod c is then held raised by the engagement of the parts' c<1>, d<1>. If the vacuum is destroyed in the reservoir, the catch parts c<1>, d<1> are disengaged by the spring f and the cam shaft is turned to the low leverage position by means of the weighted end of the hand lever q. In the lower position of the bar c, the ball valve g is seated and prevents air gaining access to the reservoir t through a faulty diaphragm e.

Filed: 1936-02-03
Abstract: 469,940. Separating gases by liquefaction. TRIGGS, W. W. (Gas Industries Co.) Feb. 3, 1936, No. 3237. [Class 8 (ii)] In a process of separation of air and other gases into constituents by liquefaction and rectification, involving expansion of the air in an engine or turbine 4 driving an electric generator 22 or other external load, a variable speed mechanism 21 is interposed between the engine and driven machine in order that the engine speed may be adjusted to the amount of gas to be expanded. Compressed air enters at 1 a cooler 27 traversed by conduits 14, 19 conveying cold gas from a rectification column 29. A part of the compressed and cooled air is branched off at 2 to the expansion engine 4 and after expansion is led into the rectification column at point 7. The other part of the compressed cooled air is led through a second cooler 28 and is expanded directly through an orifice 30 to the column. Liquid nitrogen from the bottom of the column is expanded through an orifice 8 and gaseous mixture is expanded through an orifice 10 and delivered to the top of the column. Liquid oxygen may be drawn off at 9. The changespeed mechanism may comprise toothed or belt gearing. The last shaft 31 of the changespeed mechanism may be coupled to a shaft from which the compressor of the apparatus is driven by an' electric motor.

Bending; welding.-In a process in which an electric cable sheath is made by forming strip metal, e.g. aluminium, copper or their alloys or stainless steel, and subsequently electric arc welding the seam, molybdenum disulphide lubricant is applied between the forming tools and the strip which is welded without previous complete removal of the lubricant. The lubricant in powder form is applied continuously from time to time either to the forming rolls or the strip. Pads impregnated with the lubricant may be maintained in contact with the rolls or the rolls may have surfaces capable of being impregnated with the lubricant. The seam is welded by a gas, e.g. argon, shielded tungsten electrode, and the tube so formed may be corrugated or reduced in diameter to form the cable sheath. Specification 741,235 is referred to.

IPC: F01B25/00
Filed: 1917-03-06
Abstract: 110,863. Portham, R. S. March 6, 1917. Working-fluid supply.-Consists in passing the superheated steam from a turbine stop valve, ahead or astern, through a cooler of the surfacecondensing type before reaching the inlet to the turbine, whereby the steam is reduced to and maintained at the desired reduced temperature. The device is primarily intended for the reduction in temperature of the steam for the astern turbine when manoeuvring. The cooler b, supplied preferably from the circuit of the main condensers, is mounted between the astern turbine stop valve c and the inlet of the astern turbine, and valves g, h are provided to regulate the water passing through the cooler. To effect this regulation in proportion to the steam admitted to the astern turbine, the valve h is coupled up to the main turbine stop valve spindle i. The Provisional Specification states also that the invention may be applied to reciprocating engine installations.

Filed: 1959-01-30
Abstract: 852,767. Moulding boats. UNITED STATES RUBBER CO. Jan. 30, 1959 [March 20, 1958], No. 3361/59. Class 87(2). [Also in Groups VIII and XXXIII] A boat hull is moulded from a plastic laminate 10 having an expanded cellular core 11 disposed between and integral with low-expandable outer structural sheets 12, 13, 14 and 15. The plastic for the core 11 and sheets 12 and 13 is made from a blend of a major proportion of thermoplastic resin (e.g. styrene-acrylonitrile) and a minor proportion of a rubbery material (e.g. butadiene-acrylonitrile) and a vulcanizing agent (e.g. sulphur). The core 11 composition further includes a blowing agent. The sheets 14 and 15 are made from an elastomeric material (e.g. equal parts of chlorosulphated polyethylene and butadiene-acrylonitrile rubber). The laminate 10 is heated under pressure causing the core 11 and outer sheets 12, 13, 14 and 15 to bond together, the rubbery constituents to vulcanize and the blowing agent to be decomposed and expands the core 11. The expanded laminate 10 is then secured at its periphery to a frame and is further treated so that it can be shaped by the mould 34, adapted to be lowered by the hydraulic cylinder 35 and provided with holes 36 which communicate with a source of vacuum via the flexible connections 37. The laminate may have further layers on its outer surfaces consisting of a substantially saturated elastomer (e.g. chlorosulphated polyethylene).
