Abstract: 708,592. Dispensing measured quantities of liquids. S. V. CARBURETTER CO., Ltd., and SIMMONDS AEROCESSORIES. Inc. March 30, 1953 [May 21, 1952], No. 12820/52. Class 106(5) [Also in Group XXVII] A liquid fuel metering distributer for supplying the fuel-injection nozzles of internal-combustion engines comprises a rotary disc valve 7A, Figs. 3 and 4, having an epicyclic motion under control of which one or more distensible metering chambers 12, 13 of adjustable volumetric capacity, are charged periodically with pressurized fuel and, at recurrent intervals. caused abruptly to contract and thereby rapidly eject their fuel content to a delivery outlet. In Figs. 3 and 4 the valve 7A is pressed against the end of the distributer casing 1 by a spring-loaded metering block 3 and is rotated by an eccentric 10 on a driving shaft 11 so that it rolls with epicyclic motion around a ring gear 9 on the casing 1 with which it is in mesh through teeth 8. Fuel supplied by a pump 25 to an inlet 27 enters the metering chamber 12, 13 when their inlets 23, 24 are uncovered by the epicyclic motion of the valve 7A, to force spring- loaded pistons 14 therein down against stops 17 which may be adjusted simultaneously by a gear wheel 19 to adjust the effective volume of the metering chambers. The charge of fuel in each metering chamber 12, 13 is discharged to its associated injector N<SP>1</SP>, N<SP>2</SP> under the force of the springs 15 when ports E<SP>1</SP>...E<SP>8</SP> in the valve place the metering chambers ports 21, 22 in communication with the outlets C', C<SP>2</SP>, leading to the injectors. Each part E<SP>1</SP>... E<SP>3</SP> has a cycloidal motion and in Figs. 3 and 4 the ratio of the pitch circle diameters of the gears 9 and 8 is 9:8 so that for each revolution of the driving shaft 11 the valve 7A rotates upon its axis through one-eighth of a revolution. A resilient sealing ring 30 seals the space between the .block 3 and the .casing 1, ..and the spring-loading of the pistons may be replaced by hydraulic loading. In a modification, each metering chamber is associated with two fuel injectors and in a further modification the block 3 is integral with the casing 1 and the valve 7A is urged into contact with the block by a spring. In Fig. 6, a single metering chamber 12 supplies two nozzles N<SP>1</SP>, N<SP>2</SP> and the fuel is supplied alternatively to opposite sides of a free piston in the chamber 12, so that for example the fuel supplied to the top of the piston through the port 23 drives out the fuel in the space below the piston through a passage 34 to the injector N<SP>2</SP>, the return of the piston under the force of fuel supplied to the passage 34 forcing the fuel above the piston to the injector N<SP>1</SP>. Specification 552,547, [Group XXVII], is referred to.

Title: Improvements in or relating to electrical measuring instruments for giving remote indications of quantities or measurements
IPC: G08B21/00
Filed: 1943-08-17
Abstract: 566,449. Electric measuring instruments. SANGAMO WESTON, Ltd. Aug. 17, 1943, No. 13326. Convention date, Feb. 18, 1942. [Class 40 (i)] [Also in Group XXXVI] A remote-controlled electrical measuring instrument in which a permanent magnet rotor takes up an angular position corresponding to the direction of the magnetic field produced by the stator is provided with an auxiliary magnetic system in the form of one or more split rings of magnetic material in order to move the rotor to an off-scale position in the event of the stator not being excited and to permit adjustment of the deflection characteristics of the instrument. As shown, the stator 8 carries three field coils 7 which are excited from a transmitter unit 27, Fig. 4. The rotor 16, which is disposed within a cylindrical extension 11 of the base 9, is mounted in bearings in the base and in a bridge member 12 secured thereto and carries a flat pointer 20 visible through a window 241 in the casing. One or a pair of split rings 26 of magnetic wire which fit into a peripheral groove in the base 9 are magnetized to produce diametrically opposed poles, as indicated in Fig. 3, and are disposed so that when there is no current in the field coils 7, the rotor takes up a position in which the rear end of the pointer 20 marked OFF is displayed through the window 24<1>. Moreover, it is apparent that when the field coils are excited, any deflection of the rotor from the central position shown in Figs. 1, 4 will be partly dependent on the magnetic strength of the ring or rings 26. When two rings are used, therefore, the magnetic strength may be varied to adjust the deflection without shifting the magnetic axis by displacing the rings in opposite directions, as indicated in Fig. 6.

Title: Improvements in or relating to automatic weighing apparatus
IPC: G01G13/00
Filed: 1928-05-07
Abstract: 293,445. F÷rster, O. B. July 7, 1927, [Convention date]. Automatic-feed weighers. - Apparatus for automatically weighing out material for filling into packages comprises a beam-carrying column capable of being lowered and a pivoted scale pan which, upon the beam-carrying column being lowered is emptied by its marginal flanges bearing upon an abutment, with a pan-charging shoot vibrated by a magnetic hammer break, in such a way that during the descent of the charged pan under its load the vibrating of the shoot is stopped by the opening of a circuit contact, a second circuit contact being opened during the descent of the beam-carrying column, and a fresh shaking of the shoot thereby only being permitted after the re-closing of the pan and of the two contacts, that is, after the reascent of the beam-carrying column. The scale pan g is formed of two pivoted portions i, i<1>, and receives the material from a supply hopper 82 by way of an inclined shoot 60 which is vibrated during a weighing operation by blows from an electromagnetically operated hammer 44. Alternating current from the mains 24, 25, after reduction by a transformer 23, passes to a rockable switch arm 29 adjustable over studs 31 - - 34 connected in parallel to resistances of various magnitudes. From the resistances the current passes through the magnetic hammer break 43, through a conductor 46, a spring 13, contacts 8, 7, the scale beam c, a spring-supported beam column b, a beamlowering lever x, contacts 5, 6 and back to the transformer. Continuous, instead of alternating, current may be used. When the desired quantity of material has entered' the pan g the beam tilts and opens the contacts 7, 8, thus stopping the hammer 44 and arresting the feed of material. The operator now depresses a knob 3 thereby opening the contacts 5, 6 to prevent premature re-actuation of the hammer, drawing down the beam-support b, and causing flanges l, l<1> on the pan to press upon stationary abutments n, n<1> so as to open the pan and discharge its contents down a package-filling shoot. Release of the knob allows the pan and beam to return for another cycle of operations. The knob may be held down by a catch. The quantity and speed of the material sliding down the shoot 60 may be adjusted in the following ways, viz. (a) by screwing the supply hopper 82 up or down, (b) by adjusting the inclination of the shoot by means of a screw adjustment 77, (c) by raising or lowering the hammer mechanism relative to the floor of the shoot, (d) by adjusting the hammer armature in relation to the core of its electromagnet, and (e) by adjusting the strength of the hammer blows by moving the rockable lever 29 to a different contact stud. The package-filling shoot for passing the weighed charge into the package is secured in position by a slotted flange permitting ready removal and replacement of the shoot to suit packages of various sizes. The hammer-containing box together with the feed shoot 60 may be provided as a separate unit for mounting on the supporting table of the apparatus.
