Abstract: 255,191. Jenkins, C. E. May 21, 1925. Closure members, rotary spherical.-The air inlet of a carburettor is controlled by a pair of curved blades a, b, Fig. 1, mounted on bearings in the wall of a spherical chamber x formed in the air inlet passage, and adjustably connected by radius rods d, c to tangent rods e, f attached to a control rod g operated manually or by the engine governor. In a modification, the blades a. b, Fig. 4, are each connected through an arm c and a rod f to a cross-bar i carried by a piston h, which is loaded by a spring h<1> and actuated by suction transmitted from the mixing-chamber y<1> through a passage y<2>. By adjusting a rod l<1> which limits the upward movement of the piston h, the tension of the spring h<1> may be varied.

Title: Improvements in or relating to fluid mixing valves
IPC: F16K11/065
Filed: 1962-04-06
Abstract: 1,043,241. Valves. J. M. SHEARDOWN. April 8, 1963 [April 6, 1962], No. 13421/62. Addition to 901,761. Heading F2V. In a mixing valve for controlling the flow of two separate supplies of fluid, e.g. hot and cold water, substantially as in the parent Specification, the reduction in flow experienced at higher delivery pressures due to distortion of the sealing rings is overcome by separating the peripheral valving surfaces by an interrupted groove constituting a plurality of waterways. The waterways may consist of a plurality of asymmetrically machined notches 24 within a reduced diameter portion 11 between the peripheral valving surfaces 16 and 12 of plunger 8. The tapered portion 13 of the innermost peripheral valving surface 12 is also provided with a plurality of flats 24<SP>1</SP>. Additionally, an extraction washer 25 is formed or provided at the end of the portion 13 for facilitating withdrawal of the seating ring assembly, upon dismantling of the valve, by engaging with washer 26. The notches may alternatively be provided on the full diameter of the plunger 8 or may be formed in the bore with the seating rings 15 and 14 carried by the plunger 8.

Title: Improvements in Suction Actuated Liquid Feed Apparatus.
IPC: F02M37/02
Filed: 1917-09-19
Abstract: 119,082. Marks, E. C. R., (Sparks-With. ington Co.). Sept. 19, 1917. Vacuum apparatus.-In suction-actuated liquidfuel supply apparatus wherein fuel is raised by suction from a main tank to an intermediate tank at a higher level whence it is discharged to the carburettor, the intermediate tank is divided by a partition 13 into chambers 8, 10, of which 8 is connected at 55 to the carburettor, and 10 is connected at 33 to the main fuel tank, at 25 to a source of suction, such as the engine induction pipe, and at 36 to the atmosphere. The connexions 25, 36 are provided with valves 23, 39 respectively which are actuated by a float 26 in accordance with the fuel level in the chamber 10. The float is mounted rigidly on the stem 22 of the valve 23 and carries a disk 48, to which two springs 49, 50 are connected. The other end of the springs 50 is connected to a flange 51 and that of the spring 49 to the outer end of a U- shaped lever 40 which is pivoted to depending portions 41. This lever engages loosely the stem of the valve 39 between enlargements 46, 47 thereon, and its upward movement is limited by a stop 52. Atmospheric pressure is transmitted to the chamber 8 through a pipe 53. As the fuel rises in the chamber 10, the float is raised and, when the disk 48 is above the pivot of the lever 40, the spring 49 causes the lever to snap over and open the valve 39. The valve 23 being closed or nearly closed, fuel is discharged through the nozzle 18 and non-return valve to the chamber 8. The float falls with the fuel level, the valve 23 is again opened, the spring 49 snaps the lever 40 downwardly to close the valve 39 and the chamber 10 is again filled with fuel. The valve 23 instead of controlling the suction connexion, may control the liquid inlet connexion 33. The cover 27 of the chamber 10 is secured by screws 32 to a flanged ring 28 the jointing face 30 of which has two thicknesses of metal, packing 31 being inserted. In a modified construction, the partition 13 instead of being secured as shown by soldering, welding &c., is inserted between flanges formed on the chambers 8, 10, the lower face 9 of the chamber 8 is flat instead of dome-shaped and the pipe 53 is situated outside the chamber 18.

Abstract: 954,794. Analogue computors. W. GUTTINGER. April 19, 1960 [April 17, 1959], No. 13721/60. Heading G4G. An analogue computer for statistical calculations will derive outputs analogous to the mean value x = #x i /n and the standard deviation #<SP>2</SP> = #(x i -x)<SP>2</SP>/n where x i  are the single values under consideration and n is the number of values or, alternatively, if values x i  are distributed into classes, the quantities are: #x = #f i K i /n, #<SP>2</SP> = #f i (K i -#x)<SP>2</SP>/n where K i  is the average value of class i and f i  the number of values falling into class i. One computer circuit is shown in Fig. 1 and comprises an autotransformer T having end terminals w 0 w 3  and taps w 1 w 2 w i  and energized from a source Q 1  the inductive no-load current and the iron loss no-load current being compensated for by a second energizing source Q 2  and capacitor C. Derivation of #x. The values x 1 x 2 x i  of which the statistical mean value is to be determined are represented by voltages U 1 U 2 U i  across terminal w 0  and tappings w 1 w 2 w i  respectively, the latter being connected together to a point S through resistances R 1 R 2 R i  respectively. If R 1 R 2 R i  are equal then the voltage U between w 0  and S will be the average of the voltages at points w 1 w 2  and w i  and therefore represent the mean value #x of x 1 x 2  and x i . If, alternatively, U 1 U 2 U i  represent the average K 1 K 2 K i  of x values distributed in a number of classes and the resistances R 1 R 2 R i  are inversely proportional to f 1 f 2  and f, then U will represent #f i K i /n i.e.#x. Derivation of #<SP>2</SP>. The total admittance between w, and w 3  referred to the transformer primary circuit is and the current through ammeter A is proportional to voltage U 0  and to the admittance of the primary circuit, and this current is therefore proportional to #<SP>2</SP> multiplied by the number n of values x i . If the x values are distributed in classes, and R 1 R 2 R i  are inversely proportional to values f 1 f 2 f i  the current through ammeter A will be proportional to #<SP>2</SP> for this case multiplied by n. In another embodiment (Fig. 2, not shown) currents replace voltages as the analogue signals.
