Title: Apparatus for metering and distributing fluids
IPC: G01F15/00
Filed: 1961-02-22
Abstract: 908,657. Dispensing liquids. SOC. D' ETUDES D'INVENTIONS ET DE BREVETS. Feb. 22, 1961 [March 29, 1960], No. 6544/61. Addition to 857,796. Class 116. - The predetermining apparatus of the parent Specification for a liquid-dispensing pump is modified in that the press-studs 14 for determining the amount to be dispensed are arranged in a circle and means are provided to permit quantities greater than the quantity capable of being set by the studs 14 to be dispensed under the control of the operator. A drum 16, Fig. 2, driven from the metering mechanism carries a cam 17 which operates a lever 18 to move a ratchet wheel 5 step-by-step, which wheel is integral with a notched wheel 8, the notches 8a, in which are normally masked by projections 10a, Fig. 3, on a wheel 10 driven from wheel 8 through a spring 9. On depression of a press-stud 14 it is locked in depressed position by a spring-loaded plate 7 engaging a notch 14c therein, the inner end of the stud 14 being then positioned in the path of a projection 10b on the wheel 10. During dispensing the wheels 5, 8, and 10 are rotated together until projection 10b contacts the depressed stud 14 when wheel 10 is held stationary to unmask the notches 8a and allow the end 12a of a lever 12 to pass therethrough, partially closing the liquid valve (not shown) connected thereto at 12c and causing the end 12e of the lever 12 to contact a cylindrical portion of cam 17. On continued rotation of cam 17, the lever end 12e falls into notch 17a, whereby the delivery valve is closed to discontinue dispensing at the predetermined amount. If no press-studs are operated, the lever 18, Fig. 2, operates wheel 5 until the pawl 3 reaches a smooth portion 5c, when operation of the lever 18 produces no further rotation of wheel 5 and liquid continues to be dispensed until discontinued by the operator. To zeroize the register of the pump, a lever 1 is depressed to move pawl 3 and the reverse-preventing pawl 4 away from ratchet wheel 5. A coil spring 6 tensioned during operation then returns wheels 5, 8 and 10 to their zero position and the return motion operates the return mechanism of the numeral drums of the register, as described in Specification 863,096. The lever 12 is returned to its initial position by a lever 13, Fig. 3, which also contacts a stop on disc 7 to rotate the latter slightly to free the depressed stud 14.

Abstract: 827,318. Making turbine blades; extruding. WIGGIN & CO. Ltd., H. Feb. 17, 1958 [Feb. 27, 1957], No. 6598/57. Classes 83 (2) and 83 (4). In the hot extrusion of a billet 1 of highmelting point metal, a pad 2 of more readily deformable metal is placed in front of the billet and graphite is used as a lubricant. In the extrusion of gas turbine and compressor blades, Fig. 2, the billet 1 may be an alloy of nickel and chromium or an alloy of nickel, chromium and cobalt and these alloys may include small quantities of aluminium and titanium; alternatively molybdenum-base or zirconium base alloys may be used. The pad 2 may be of nickel, copper-nickel alloy or mild steel and may be welded to the billet or deposited on the leading end from a welding rod. Graphite is applied to the face of the extrusion die and coats the metal passing therethrough. To reduce chilling the pad 2 is held out of contact with the die before extrusion pressure is applied by a wooden stick pushed through the die or by the ejector mechanism. The pad forms a coating which may produce a taper on the leading end of the extruded blade 5; this coating may be removed subsequently by machining or the coated leading end may be cut off. Reference has been directed by the Comptroller to Specification 732,081.

Filed: 1944-04-22
Abstract: 566,737. Firelighters. IRELAND, J. April 22, 1944, No. 6836/43. [Class 50] [Also in Groups V and XXX] Sawdust, peat, paper, &c. is delivered from a hopper A into moulds B supported by a stationary table or, as shown, by a conveyer C, 'and the filled moulds are loaded into trays or baskets F pivotally mounted on a wheel E which is almost half submerged in heated inflammable impregnating liquid contained in a tank D. The wheel is rotated clockwise intermittently, and as the trays pass through the upper part of the tank after having been dipped, the moulds are cooled by cold air or by arefrigerator. When each tray has completed one revolution, the moulds are removed therefrom. The hopper A is pivoted at a and comprises flow-regulating baffles a<1>, pins a<2>, which prevent the sawdust &c. forming into a solid mass, a wire mesh covering a3 to prevent entry of large pieces, a hinged door a<4> normally held closed by a spring a<7>, and an operating handle a<6> ; when the operator pulls the hopper in the direction of arrow 2 he simultaneously presses a rod a<5> on the door to open the latter. The mould B, Fig. 5a, is divided into compartments by partitions b<2> which terminate below the top of the mould, the firelighters being thus formed as a single block which may be readily broken into individual firelighters. A cover J has a front edge j formed as a scraper which removes excess material from the mould. The cover is pushed into place by a handle j<8> and secured by pins b<4> which enter holes in the edge j and slots j<6> in the cover sides. Instead of the scraping edge j, the front part of the cover may have a roller which removes excess material and compresses material in the mould. Hollow firelighters may be made by providing projections upstanding from the mould bottom, and the hollow in each firelighter may be filled with chips, shavings or other inflammable matter. Instead of a cover, the bottoms of moulds which are to be stacked on the trays may be formed as covers, as shown in Fig. 14, the edge jof each mould being used as a scraper.

Filed: 1916-05-18
Abstract: 107,216. Stone & Co., J., and Darker, A. H. May 18, 1916. Exciting; dynamos, regulating. -In an installation comprising a self-regulating variable-speed dynamo c, one or more batteries o, o<1>, and a lighting or other consuming circuit l, the dynamo field magnet is provided, in addition to the main winding g connected between a main brush b and a subsidiary brush d, with an auxiliary magnetizing winding p which is connected in parallel with a resistance n<1> in the consuming circuit l; the output of the dynamo is thereby adjusted automatically to suit different demands in the consuming circuit. A second resistance n may be arranged in the consuming circuit. The resistance n or the resistance n<1> may be short-circuited across switch-contacts q<2> at low dynamo speeds, the short-circuit being broken on the closing of the electro-magnetic cutin switch q. An adjustable resistance r, Fig. 2, in the circuit of the field-magnet winding g may be short-circuited by a plug inserted between terminals r<1> when it is desired to charge a battery which has considerably " run down "; the resistance r may be cut in automatically by an overcharge switch when a state of full charge is reached. Fig. 2 shows a two-battery system in which a change-over switch o<2> of the kind described in Specification 7469/10 is used for connecting one or other of the batteries o, o<1> to the main j through the resistance n. In a moctification, an additional field-magnet winding which may assist or oppose the windings g, p is connected through the switch o<2> with that battery which, for the time being, is connected to the main through the resistance n. In a further modification, another demagnetizing field-magnet winding may be placed in circuit by a battery overcharge switch when the battery is fully charged. An arrangement of this kind is shown in Fig. 4; the demagnetizing winding g<2> is connected across the brushes b, d so as to assist the windings g, p when the contact-lever u of the overcharge switch rests upon the contact v; when the battery is fully charged, the solenoid t sucks up its core making contact at w. The winding g<2> is thereby connected across the brushes d, b<1> so as to oppose the winding g. In a bipolar dynamo, the windings g, g<2> are preferably mounted on one limb and the winding p on the other limb; the windings g, g<2> may be constituted by a single bobbin or coil divided into sections. For train-lighting, a pole-changer of the kind described in Specification 4073/12 may be employed, contacts b<2>, b<3> connected to and rocking with the brushes engaging terminal slippers j<1>, k<1>. The field-magnet poles may be fitted or formed with pole-tips or extensions, and commutating interpoles may be employed. The dynamo may be run as a slipping- belt machine by removing the subsidiary brush d and connecting the windings g, g<2> across the brushes b, b<1> in series with a resistance. Specification 7589/14 also is referred to.

Abstract: 825,595. Fluid pressure brakes. NEIL, G. March 7, 1958, No. 7394/58. Class 103 (1). In a brake system, particularly for rail vehicles, of the type in which the brake cylinders are of the twochamber type in which the pressure operative in the brake pipe 12 acts below the piston 4 and the space 10 above the piston forms a reservoir for compressed fluid for operating the piston on reduction of the brake pipe pressure, the upper space is separated from this piston by a quantity of liquid which contacts the piston and cylinder wall over their entire sliding seal surface. The upper space is divided into two compartments by a partition member 7 having an aperture 8 therein. The liquid may be prevented from passing the piston 4 by the use of a suitable ellipsoidalshaped sealing ring 11, the object of the invention being to prevent the reduction in air pressure above the piston due to leakages that may otherwise take place without it being apparent to the user of the vehicle. In the arrangement shown in Fig. 1, the lever 1 is linked to the brake shoes, a pawl 14 being shown which may be engaged with a pawl 15 on the rod 3 to lock the brakes in the " off " position, to which position the rod may be moved by a snail cam 16.
