Abstract: 820,118. Fluid-actuated valves. HOBOURNEATON MANUFACTURING CO. Ltd. (Eaton Manufacturing Co.). Feb. 2, 1956, No. 3309/56. Class 135. A flow divider valve, e.g. for hydraulic systems, comprises a housing having an inlet 50, and main and secondary outlets 51, 52 cooperating with a hollow valve member 49 slidable against spring 62 under a pressure drop across a restriction 67 between the inlet and main outlet, and a relief valve 58 slidable within the valve 49 and biased at 60 in the opposite direction to the bias of spring 62 on valve 49. A pump passes fluid from inlet 50 via restriction 67 to outlet 51 leading to an "open-centre" valve controlling a fluid motor, e.g. for vehicle steering and, when required, via outlet 52 to an " open centre " valve controlling another fluid motor, e.g. for an hydraulic lift device or vehicle brakes. Flow through the restriction moves the valve 49 to the right to open port 52 through openings 65 to the inlet. Should pressure in the main outlet rise unduly, piston valve 58 is moved to the left to relieve pressure through a port 66 in valve 49 and outlet 53 leading to the pump inlet. The valve 49 assumes a position of balance and carries a dash-pot piston 63 at one end. The valve ensures a continuous constant rate of supply of fluid to the main outlet, and fluid in excess of such supply passes to the secondary outlet.

Abstract: 758,443. Boring-heads. WILLETT, V. W. May 5, 1954 [Feb. 10, 1953], No. 3712/53. Class 83 (3). A boring-head of the brake-ring type comprises a gear reduction-train between the brake-ring and a tool-slide, and manually-operable gear selectors with means for effecting a quick return of the slide either independently, or through the gear-train. The tool-holding slide 21, Figs. 3 and 4, is guided in ways 29 in the body 19 and may be clamped during boring operations by a screw 68, Fig. 4. The slide is fed, for facing operations, by a screw 23, Fig. 3, which may be rotated through a socket-head 33, or by change-gearing described below. A shank 13 is secured to the body by screws 20, and a flange 12 integral with the shank, encloses an arcuate brake-piece 8 against a rotatable ring 2 provided with gear teeth on its inner end-face. A shoe 3 is secured by screws to the brakepiece 8 and a screw 10, Fig. 2, enables the shoe, brake-piece 8, and gear-ring 2 to be clamped together. When the shoe is held, either by hand or by a rod 11 engaging a fixed part' of the machine, the gear-ring is stationary relative to the remainder of the rotating toolhead. Diametrically-opposite gear-wheels 36, Fig. 3, on stub shafts 37, rotatable in the body 19, engage the gear-ring 2, and further gearwheels 43 on the stub-shafts may engage either a slidable wheel 40, Fig. 2, or a slidable wheel 41, thus giving forward or reverse rotation respectively to a shaft 38 on which the wheels 40, 41 are slidably keyed. These wheels may occupy a neutral mid-position as shown, in which no drive is transmitted, and are moved into engagement by a spindle 58, extending to an opening in the head, which has a pair of eccentric pins at its inner end engaging inclined slots in a slide-bar 55. The latter has notches which engage flanges 57 integral with the gearwheels 40, 41. The shaft 38 carries a worm 47 which engages a worm-wheel 48, Fig. 4, on a transverse shaft 51. A further worm 49 on this shaft drives a worm-wheel 50, Figs. 2 and 3, on a shaft 39 parallel to shaft 38. A slidable gear 42 on the latter shaft is engaged or disengaged from a pinion 34 on the feed-screw by a forked slide-bar 60 similar to that for sliding the gears 40, 41. The screw 23 may thus be hand-adjusted when the gear 42 is in the disengaged position. An adjustable stop-bar is provided for automatically sliding the gears 40, 41 into the neutral position. Different gear ratios in the feed drive may be provided for. Specifications 554,820, 633,465 and 758,488 are referred to.

P., 41, Glebe Avenue, Enfield, Middlesex, and AUSTEN, P., 11, Victoria Road, Edmonton, London. Feb. 10, 1932, No. 4005. [Classes 38 (ii) and 38 (iv).] A system for charging batteries in a circuit 7 from A.C. mains 19 through hot cathode vapour discharge tubes 1, 2 comprises means, e.g. a contactor 14 operated by a synchronous motor 4, which inserts the batteries into the rectifier circuit a predetermined time after the application of A.C. to the rectifier valve cathodes. A relay 9 is responsive to the battery voltage and, at a low voltage, closes its lower contacts 10 which energize a contactor 8 from the A.C. supply through the contacts of an over-current relay 15 in the battery circuit. Closure of the contactor 8 energizes the synchronous motor 4 and rectifier transformer 3 and hence the valve cathode filaments and, after a time delay, the motor 4 closes holding contacts 6 for the contactor 8, opens auxiliary contacts 25 in the motor circuit by momentarily tilting a mercury switch 12 which is then held tilted by a winding 13 energized in parallel with one of the valve filaments. The switch 12 closes the circuit of the contactor 14 across the battery terminals which operates and closes the main connection between the mid-point of the transformers at tappings on a switch 20, through an ammeter 21 and the battery to the anodes through chokes 22. When the battery voltage reaches its gassing value relay 9 opens its contacts 10 and closes its upper contacts 11 which energize the motor 4 and open contacts 6, close contacts 25 and re-tilt switch 12 a predetermined time after relay 9 operates, so as to de-energize contactor 8 and relay 14 and shut down the rectifier. Failure of the A.C. supply de-energizes windings 13, 8 and the time delay must be repeated when A.C. is restored. A pushbutton 19 de-energizing relay 9 permits of the cycle being performed at any desired time. The system may be used as an emergency arrangement supplying emergency lights &c. in the event of failure of the A.C. supply, an A.C. relay 16 controlling contacts of a D.C. relay 17 which closes the circuit of the emergency system 7, 18 being provided. Over-discharge under emergency conditions may be prevented by the relay 17 opening its contacts at low battery voltage. Relay 16 may be designed so that the emergency supply may come into action on partial failure of A.C. supply. The current relay 15 opens the circuit of the contactor 8 in the event of excessive or reverse battery current.
