Patent GB-237979-A (GB)
Title: Improvements relating to drilling, boring, turning, milling and other cutting machines
IPC: B23B39/16
Filed: 1924-05-06
Abstract: 237,979. Ord, L. C. May 6, 1924. Drilling - machines; driving- machines.-In a boring, drilling, turning or other cutting-machine in which the relative motion between the tool and work is more rapid before and after than during the cutting operation, the motion is produced by a cam, or a cam and weight or spring, rotated by two independent agencies which act simultaneously while the tool is in engagement with the work but which at other times produce the high and. low feeds respectively. The two agencies operate through one - way clutches and are controlled automatically by the resistance of the work. As applied to a drilling-machine the spindlehead a is fed by a rotating cam g acting on a roller h on the machine frame c. For slow power feed the cam is rotated by a worm-wheel j actuated from the electric motor f which drives the spindles b, and for rapid idle feed by a pinion k engaging a rack which may be reciprocated by hand or fluid pressure, or by a weight or spring. When a spring is used it may be contained in a cylinder moved axially by a hand-operated pinion engaging a rack on the cylinder. Springs or weights i, y, return the spindle-head and rack respectively after a cutting operation. The cam is connected to the pinion and worm-wheel by one-way clutches o, s, respectively, the. teeth being yieldingly engaged by springs q, t, or weights and being of opposite hand. In operation the drill-head is advanced to the work by the rack and pinion k, the clutch teeth s being overridden. On encountering the work the resistance becomes too great for the rack and a power feed is imparted by the worm-wheel until the cutting operation is completed when the rack again rotates the cam until the roller h meets its highest point, further rotation being prevented by a stop w on the cam meeting a ledge x on the rack and the clutch s being disengaged by a ramp v. The head and rack are then returned by the springs &c. and stop w is disengaged to allow another feed operation to take place. The motive fluid mav be controlled automatically, or by a timing device if a sequence of operations is to be performed, and a number of machines operating on the same or different pieces of work may be co-ordinated by being controlled from a common valve.

Title: Improvements in and relating to methods of and apparatus for absorbing decompositionproducts in liquid-insulated electrical apparatus
IPC: H01F27/08
Filed: 1944-06-12
Abstract: 595,752. Presssure-relieving devices for fluids. BRITISH THOMSON -HOUSTON CO., Ltd. June 12, 1944, No. 11240. Convention date, June 12, 1943. [Class 135] [Also in Group XXXV] The pressure of hydrogen halide gas formed by the decomposition, by arcing, of an insulating liquid halogenated hydrocarbon in a transformer tank, liberates a fixative substance to neutralize the gas. Fixed to a bracket 19 in the tank is a plunger device, 15 comprising a plunger 16 urged by a spring 20 towards a frangible bottle 14 containing the fixative. A flat 25 on a rotatable shaft 24 normally latches the plunger 16 at a cut-away section 23 thereof, and a latch arm 30 on shaft 24 is restrained by the cut-away end 29 of a shaft 26. Compression of the bellows 22 by pressure due to gas products of decomposition causes a spindle 21 to pull down a lever 27 and rotate shaft 26, so releasing the plunger 16. The halogenated hydrocarbon may be that described in Specification 394,776, [Group XXXVI], and may itself initially contain some of the fixative. The latter may be as described in Specification 473,441, [Group XXXVI], or, alternatively, an aqueous solution of a strong inorganic base such as caustic soda may be used. If in spite of the additional fixative, the pressure in the tank rises unduly, a plunger-unit 17, similar to that 15, and mounted in the lid 7, operates to break a glass diaphragm 18 and liberate the gas. Both members may be set against the pressure of a spring 28 by lock-nuts 35.

Abstract: 400,247. Electrolytic cells. EVANS, D. J., Glen Cairn, Shipbourne Road, Tonbridge, Kent. April 20, 1932, No. 11329. [Class 41.] The electrodes consist of rectangular graphite slabs g, Fig. 1, spaced to form a vertical gap through which the whole of the liquid passing through the cell flows. The electrodes are mounted in ebonite holders h secured to the side walls of the cell and are provided with lead-in conductors j of the kind described in Specification 390,647. The electrode surfaces preferably stand out clear of the holders. The gap between the electrodes is adjustable by means of packing strips h<2>. In a modification, Fig. 5, four anode holders h are mounted in recesses l in the interior wall of the cell to form gaps with a central square metal cathode m. The cathode may be hollow and an additional anode n provided within it. The electrodes m, n are mounted between liquid-distributing chambers and connection is made to them by rods m<1>, n<1> passing through the cover. In order to equalize passage of liquid through the gaps, the cover may be hemispherical or cylindrical and provided with a tangential outlet to produce a turbulent flow. The cell may be made of moulded ebonite or a synthetic resin.

Abstract: 358,927. Filters. PICKARD, J. A., 21, Rosemont Road, Acton, ROGERS, F., Windsor House, Victoria Street, and MITCHELL, W., 139, Regency Street, all in London. April 11, 1930, No. 11491. [Class 46.] A reverse cleansing flow is forced through an inwardly-drained filter element by means of a plunger working in a cylinder through which the filtrate is passed after leaving the element. The filter element shown is built up of spaced discs 19, Fig. 5, around a hollow or fluted rod 17. The liquid enters the casing 4 from an inlet 10, Fig. 7, through a bore 9, formed in a lateral extension of the casing, and a duct 14. The filtrate leaves the element through a cylinder 21, formed in the cover and connected by a duct 15 with the end of the bore 9 and an outlet 11. When a plunger 22 is moved along the cylinder it cuts off the duct 15 and drives the liquid in the cylinder backward through the filter element. The plunger returns to its initial position under the liquid pressure and a spring may be provided to aid its return. The bore 9 is provided with a spring-closed byepass valve 12. The cleansing of the filter element may be aided by scrapers 28, Fig. 8, carried on a ring 29 having holes engaged by teeth on a disc 31 rotated by means of a handle 33. The bore 9 may be formed in the cover parallel to the cylinder 22. The casing 4 may be provided with cooling fins 6. The filter is suitable for use in the main lubricating circuit of an automobile or in a shunt of the main circuit.

Abstract: 768,326. Hose couplings. PHILIPS ELECTRICAL INDUSTRIES, Ltd. April 22, 1955, No. 11765/55. Class 99(1) A tubular metal insert 3 attached to a hose has an outwardly extending flange 4 which is received within an annular recess 5 formed in a sleeve 1 of elastic material secured as by bonding to an insert 2 also attached to a hose. A ring 7 removable from a position in which the sleeve and insert 3 are retained in fluid-sealing relationship encircles the sleeve. As shown in the upper part of Fig. 1, the recess and flange each have oppositely directed and co-operating conical surfaces 4a, 6a and 4b, 6b so that effective sealing of the coupling is obtained against pressures above or below atmospheric pressure. The retaining ring 7 is slidable on two axially separated sets of plastic or metal rods 11, 11a embedded in and bonded to the external surface of the sleeve; the rods in each set are spaced apart circumferentially. The external diameter of the flange 4 is slightly greater than the diameter of the recess, and to prevent withdrawal of the ring from the sleeve the latter is provided with flanges 1a, 1b. In the modification shown in the lower part of Fig. 1, one wall 8 of the recess 5 is normal to the axis of the insert 3 the flange of which has a corresponding wall 9; the sleeve has an annular groove 10 adjacent the wall 8. In an alternative form, a split retaining ring 12, Fig. 2, is used, the free ends 16 of the ring being turned inwardly to engage upturned edges of a plate 17 partially embedded in and bonded to the sleeve 1, and the opposite ends 13, 14 being hinged on pins 15a, 15b held in a plate 15 also partially embedded in and bonded to the sleeve. In a further modification, Fig. 3 (not shown), the sleeve has an annular recess of rectangular crosssection provided with rounded corners engaged by corresponding corners of the flange 4, a groove having oppositely directed conical side walls being formed in the peripheral surface of the recess.
