Abstract: 1,182,057. Mixing in proportions; sand classifier. BARBER-GREENE CO. 23 July, 1968, No. 35015/68. Headings B1C and B2N. [Also in Division G3] In apparatus for preparing sand mixtures containing desired proportions of various particle sizes, a sand/water slurry flows through a hydraulic sand classifier and deposits sand along its V-cross-section settling tank 16 according to grain size. There is a plurality of pneumatic-sleeve discharge valves 31-39 (see also Fig. 2 not shown) each forming a classifying station in association with a pivotable shoot 61-69, or flexible spout (see Fig. 12, not shown) which can be pivoted by a pneumatic actuator (see Figs. 6, 7, 8, 9 and 12, not shown) or other means selectively over first or second product flumes 140, 142 or a waste flume 144. The discharge valves can be opened until there is sufficient depth of sand in the classifier as sensed by the torque required to rotate the paddles (116, Fig. 2 not shown) of sand level indicators 51-59. A control device, which may be manually preset or operated by a punched card or a magnetic tape programme, then positions the shoots over the respective first and second product flumes for times proportionate to the quantities of sand of each particle size required in the first and second products.

Abstract: 817,674. Electric indicating systems. ENGLISH ELECTRIC CO. Ltd. Dec. 6, 1955 [Dec. 6, 1954], No. 35319/54. Class 40 (1). [Also in Group XIX] In an integrating accelerometer which may be controlled in accordance with stored information the number of revolutions of a rotor inside a stator is a measure of the distance moved by the device. As shown, Fig. 2, the rotor 30 is. rotated in accordance with the energization of its stator 32. The latter is mechanically unbalanced relative to the axis BB so that acceleration in a plane perpendicular to BB will tend to cause a displacement of 32 about BB which is detected at 38 and controls the energization of 32 from control unit 34. Prior to acceleration measurements being taken on 30, 32, for example in a guided missile prior to take-off, the accelerometer is given a predetermined control by means of device 31, 33. The rotor 31 is coupled to 30 and is rotated by stator 33 which is energized in accordance with stored information from unit 42. When the restraint from 42 is removed a control system 39, 35 governs the action of 31, 33 similarly to 38, 34. In an alternative form, not shown, when the restraining control of 42 is removed from 31, 33 the latter are mechanically coupled to the accelerometer 30, 32 and are then subject, with 30, 32, to the control of 38, 34.

Title: A phase-rotation sense indicator for polyphase electrical systems
IPC: G01R29/18
Filed: 1954-12-07
Abstract: 797,591. Phase sequence measurement. RUSSELL, R. L. March 7,1956 [Dec. 7, 1954], No. 35473/54. Class 37. The sense of phase rotation in a polyphase supply is determined by connection of a resistance in series with a capacitance or inductance across any two phase voltages and connecting a current sensitive indicator from the junction to neutral, whereby the indicator exhibits maximum response when its associated resistance is connected to the leading phase voltage. The indicator circuit is particularly adapted to a balanced biphase system (Fig. 1, not shown) and in a modification (Fig. 2, not shown) may be duplicated with an indicator for each sense of phase rotation. In Fig. 3, resistance R3 is connected between phase A and the junction of resistance R5 and capacitance C5, selectable by switch S1 for connection to phase B in series with capacitance C3, while resistance R4 is similarly connected between phase B and the junction of capacitance C6 and R6, selectable by switch S2 through capacitance C4 to phase A. Current indicators M1 and M2 are connected from the junctions to neutral and for two phase circuits C3 and C4 are switched in series with C5 and C6, while for three phase circuits they are switched in series with resistances R5, R6 respectively. Indicator M1 reads maximum when phase A leads phase B while indicator M2 reads maximum when phase B leads phase A. Tungsten filament lamps, neon lamps, gas discharge tubes, or A.C. sensitive relays and measuring instruments may be used as indicators, and the capacitances are replaceable by inductances of appropriate values.

Title: Foot operable control apparatus for controlling the throttle valve of the engine of an automobile vehicle
IPC: F02D9/00
Filed: 1958-11-06
Abstract: 850,996. Regulating. ANCIENS ETABLISSEMENTS PANHARD & LEVASSOR S.A., DES. Nov. 6, 1958 [Nov. 14, 1957], No. 35718/58. Class 7(6). [Also in Group XXXI] The throttle valve of an automobile engine is controlled by an apparatus comprising a pedal having a small amplitude of displacement acting upon an hydraulic distributing valve which delivers liquid under pressure proportional to the pressure upon the pedal, a device which exerts an opposing action proportional to the engine speed and a connection to the throttle valve movable under the combined influence of the pedal pressure and the opposing pressure, the pedal pressure being in the direction to accelerate the engine. As shown, a pair of valves 2 of identical construction are connected, via an hydraulic accummulator, by pipes 15 to a pump 16 driven by the engine. Each valve 2 has two compartments separated by a valve 11 which is normally kept shut by the pressure of the fluid generated by the motor 16. The valve 2 also comprises a foot operated element 3, normally held in the rearward position by a spring 7 and which has passages 8 which, in the rearward position communicate with the pipe 19 which is in communication with a reservoir 20 of the pump 16. On depressing the element 3, the passages 8 are closed by a needle valve 10 attached to the valve 11 and the valve 11 is opened. A pump 32, e.g. the main lubricating oil pump of the engine, supplies fluid to a cylinder 28 which provides a pressure dependent upon the speed of the engine to a piston 27 connected to a lever 25. The lever 25 is also connected to a piston 24 which is operated upon by the fluid from motor 16 when the valve 11 of one valve 2 is opened, piston 27 providing a back pressure. The lever 25 is also connected through an arm 29 to the throttle control valve. The exit port 21 (through the valve 11) of the other valve member 2 is connected to the brake cylinders 22. Instead of the oil pump 32 fluid pressure dependent upon the speed of the engine may be generated from devices operating in response to a centrifugal governor, or the piston 27 may be connected to the intake manifold in a manner such that the suction tends to close the valve. The throttle valve is moved to the open position until the lever 25 is balanced by the pistons 24 and 27. When the valve 11 is shut (e.g. by means of the driver's foot from the element 3), liquid from 24 returns to the reservoir 20 via the passages 8 and the throttle is closed by pressure from the pump 32 (or alternative mechanism).
