Filed: 1958-10-01
Abstract: 843,739. Pelleting machines. METALLGESELLSCHAFT A. G. Oct. 1, 1958 [Jan. 2, 1958], No. 31377/58. Class 87(2). [Also in Group XXX] Freshly formed pellets P, Fig. 4, particularly pelletised ores, are conveyed from the forming machine to the sintering machine by a roller conveyer 4 to which they are fed at such a rate that pellets lodging in the valleys between adjacent rollers nevertheless become entrained, rolling in frictional contact with the rollers and with each other and so becoming compacted during conveyance. The diameter of a roller should be not more than ten times the diameter of a pellet and not less than half its diameter. It is stated that the best results are obtained for pellets of diameter between 20 and 25 mm. by rollers of a diameter between 40 and 100 m.m. The rollers are spaced so that at least the top half, and preferably more, of the lowest pellets will project above the horizontal plane in which the tops of the rollers are situated. The width of the conveyer at its charging end 11, Fig. 5, is less than the width at its delivery end 12, and the separation of the rollers near the delivery end may be slightly greater than elsewhere. A plate 13, Fig. 6, distributes the pellets evenly. The apparatus may be used to increase the diameter of the pellets by supplying unpelleted material with them, or to make pellets by supplying material mixed with starters.

Filed: 1964-02-06
Abstract: 1,060,774. Control of several motors. HYDRIL CO. Feb. 6, 1964, No. 31758/66. Divided out of 1,060,773. Heading H2J. [Also in Divisions E1 and F2] The valves 235, 236, 239 of an underwater wellhead are each actuated by electrical circuits (272), (272a) on a vessel 256. The valves 235, 236 control the flow of production fluid to a barge 238, and the valve 239 controls the flow of mud or other fluid through the pipe 240 to the well. Fluid is supplied by a pipe 255 to a chamber 250 which contains motors and valves controlling flow to the actuators 241, 242, 243 of the valves 235, 236, 239 respectively, the current for the motors being supplied by cable 292. In a modification (Fig. 2, not shown) the valves 235, 236, 239 are directly coupled to actuating motors. A reversible motor (271) (Fig. 3, not shown) is typical of one of the motors in the chamber 250, or one of the valve actuating motors in the modified construction. With the current switched on the power is insufficient to move the motor but lamps (290), (290a) glow dimly. When the switch (287a) only is depressed the motor rotates its valve and the lamp (290a) glows brightly before going out as the motor operates a pressure or a torque switch (295a) when the valve closes fully. The valve is opened by depressing switch (287) only, the lamp (290) glowing brightly before going out as the valve is fully opened. An emergency D.C. supply 301 is provided. In a modified circuit pressure switches adjacent the switches (295), (295a) cause further lamps to indicate that the valve is between open and closed positions.

Title: Improvements in or relating to electronic control apparatus
Inventor: SMITH ALFRED JOHN
IPC: G05B11/01
Filed: 1947-12-02
Abstract: 644,084. Automatic temperature control systems. ROLLS-ROYCE, Ltd. Dec. 2, 1947, No. 31860. [Class 38 (iv)] [Also in Groups XXXVII and XL (c)] In electronic control apparatus in which the anode of a single valve is supplied with a pulsating D.C. voltage alternately through a pair of circuits, the valve is rendered conductive during alternate pulses from one circuit or the other according to the phase-sense of an A.C. signal applied to the grid. In a system, Fig. 4, for controlling the throttle 26 of a gas turbine to maintain constant exhaust gas temperature, a resistance R3 responsive to the latter forms part of a bridge circuit 30, supplied with A.C. at 31, the output of which is connected through a two-stage amplifier 32 and a further amplifier 34 to the grid-cathode circuit of a triode valve 10, the anode supply to which is pulsating D.C. from a full-wave arrangement of metal rectifiers 13 associated with an A.C. source having the same frequency as the A.C. supply to the bridge circuit. A rheostat R5 is adjusted so that the bridge is balanced at the desired temperature, and temperature deviation in one sense or the other determines the phase sense of the A.C. signal applied to the grid circuit of valve 10 and hence determines which rectifier 13 passes current during periodic conductivity of valve 10. This in turn determines the phase of the anode current pulses which pass through a winding 23 of a two-phase motor, the other winding 24 of which is supplied through a condenser 25 from the A.C. source so that the motor runs in the appropriate direction to effect the necessary correction of throttle adjustment To prevent conduction of valve 10 when the A.C. signal applied to its grid is zero and yet permit conduction of the valve during a complete half cycle when an A.C. signal is present, pulsating grid bias in phase with the anode voltage is derived through rectifiers 17 and 18. H.T. supply to amplifier 34 is derived from rectifiers 13 through a smoothing circuit 22, 22a. Control systems in which control devices are connected in each of the rectifier circuits are referred to.
