Abstract: 1452540 Metering particulate material NIPPON LIGHT METAL CO Ltd 13 March 1974 11174/74 Heading B8N [Also in Division C7] Apparatus for feeding and distributing particulate material comprises an inclined generally V-section feeding trough 8 for receiving particulate material, a plurality of distribution pipes 9 communicating with the trough at spaced points along its length and projecting downwardly therefrom, a metering receptacle 10 at the lower end of each pipe for collecting particulate material gravitating down the pipe, and discharge means for each receptacle 10 operable to discharge particulate material collected therein. As described the apparatus is used to supply alumina to an electrolytic cell 1 including a bath 6 of electrolyte, and carbon anodes 5 supported from bus-bars 3. The trough 8 has a porous bottom 82 above channels 83, and each receptacle 10 has a porous bottom 111 above a chamber 112. In operation compressed air is supplied to the channels 83 so that alumina flows along the trough 8 and down the pipes 9 to fill each of the receptacles 10 in turn. When the last receptacle is full a detector 10A is actuated to cut off the air supply. At a desired time compressed air is subsequently supplied to the chambers 112 so fluidizing the alumina lying on the porous bottoms 111 and allowing it to flow from the receptacles 10 via discharging passages 113 and delivery pipes 12 on to a crust 7 formed on the electrolyte bath 6. Chisels 14 having collars 16 guided in the pipes 12 are advanced by hydraulic devices 13 to break the crust 7 and allow the alumina to enter the bath 6.  The pipes 9 and receptacles 10 are telescopically connected so that the volume of material dispensed at each operation can be varied.

Title: Apparatus for determining the value of one of a plurality of parameters of a heat exchange process
IPC: C21D1/28
Filed: 1973-03-07
Abstract: 1429945 Analogue simulators SOC DES ACIERS FINS DE L'EST 7 March 1973 [9 March 1972] 11205/73 Heading G4G The temperature of the flue gases in a heatexchange annealing process is found by repeatedly calculating in an analogue simulator the value of a prescribed operating parameter and comparing the calculated value with a desired (pre-set) value of the prescribed parameter, using for this purpose an estimated value of the sought temperature, repeatedly adjusting the value of the sought temperature until the calculated and pre-set values of the prescribed parameter are equal. The analogue apparatus may simulate the heat-treatment furnace of Fig. 1 in which products are conveyed through two hot-gas heating/cooling ovens 4, 5 separated by a dead space 19. For a given velocity v of products through the furnace, the heatexchange process in each oven may be represented by the differential equation:- where #t is an element of dwell time, ## is an elemental variation of product temperature, # is the instantaneous product temperature, T is the blowing temperature, Z is the oven temperature, C is a product heat-capacity parameter, A is a convection coefficient and B is a radiation coefficient. In the computer of Fig. 3, ## is formed in module 101 using ## = (# 0 -#F)/n, where # 0 , #F are respectively initial and final product temperatures set on potentiometer 109a and n is arbitrary. The quantities C(#) = M#+N and Z(T) = KT+L are respectively generated in modules 102, 103 from values of M, N, K and L which are characteristic constants of the ovens 4, 5. The variables # and T are supplied from clock-actuated potentiometers 109b, 110a and fed to module 108 which calculates (#-T). The time element #t is calculated in an obvious manner in modules 104, 105, 106, 107 from the various input factors and summed in module 114, which may be a recording device, to yield total dwell time. This is compared in a comparator 116 with the prescribed dwell-time tF and the difference fed to the command circuit 117 of motor 110b which adjusts the potentiometer 110a by an amount  #T.

The operation of an hydraulic actuator 2 is controlled by a main valve 22 itself controlled by a remotely positioned pilot valve 42 connected to the main valve by pilot lines 8, 10 which are selectively pressurized by operation of the pilot valve to cause corresponding actuation of the main valve, the pilot line not pressurize acting as the return line for hydraulic fluid returning from the actuator 2, whereby the pilot lines are flushed during operation. In the position of the pilot valve 42 shown, the pilot lines 8, 10 are connected to a return line 16. Actuation of the pilot valve 42 pressurizes one or other of the lines 8, 10 from a pressure main 12. Assuming the line 8 is pressurized, the main valve 22 moves to its position 1 in which pressure fluid from the line 12 flows to one side of the actuator through a line 6 to cause operation in one direction. Fluid displaced from the other side flows through lines 4, 10 to the pilot valve 42 where it is directed through a volume meter 53 before entering the return line 16. The meter 53 has an associated indicator 55 which provides an indication of the position of the actuator 2. The main valve 22 may be manually operated and may be provided with means for indicating the actuator's position, Fig. 3 (not shown).

Abstract: 382,288. Antiaircraft gun sights. VICKERS-ARMSTRONGS, Ltd. and WATSON, J. P., Vickers House, Broadway, Westminster. April 16, 1931, No. 11331. [Class 92 (ii).] Relates to sighting apparatus, particularly for antiaircraft guns of small calibre, in which the rear end of the sight bar F is connected to a variable-throw crank P which is adjusted angularly to suit the course of the target and as to its throw in accordance with ST/R, where S is the target speed, R the range, and T the time of flight of the projectile, the sight bar being articulated to a link E of fixed length kept parallel to the gun B. According to the invention, a member is moved in accordance with the factor R/T by combining the displacement of a member D moving automatically in accordance with quadrant elevation (E) with the displacement of a member moving in accordance with target height (H), the resultant movement being combined with a movement according to S to adjust the crank throw in accordance with ST/R Fig. 2 shows one construction in which one side wheel g of a differential gear G<3> is driven from the member D in accordance with log E obtained from a cam G, the planet wheel h being adjusted in accordance with log H obtained from a dial H<1>. The resultant motion of the other side wheel j is combined by a differential gear K with log S obtained from a dial L<1> and passed to an antilog cam M which causes a shaft N through shaft P<2> and rack gear P<1> to displace the crank pin by the calculated throw. - The rear sight head r is carried by a sleeve r<1> which is adjustable to suit the course of the target and thereafter maintained in adjusted position during gun training by gearing S<1>, S2 connected to a fixed rack on the gun through a clutch S<4>. A differential gear s compensates for undesired movements of the shaft P<2> which might occur during course adjustments. The sight head r is vertically adjusted for tangent elevation by a cam T rotated from a shaft J<x> driven by the wheel j which also serves to rotate gears V, W to give the settings for drift and fuze respectively. In a modification, Fig. 3, the rotation of the shaft J<x> is obtained by setting a pointer h<x>, screw threaded on the shaft, to appropriate height curves on a drum G<x> rotated from the member D in accordance with quadrant elevation.

Abstract: 331,602. Heenan & Froude, Ltd., and Walker, G. H. Jan. 10, 1930. Straight-tube apparatus having internal baffles; plate apparatus.-In heat exchanging apparatus one or more cores are interposed in the path of the moving fluid, the cores being formed of a metal ribbon or strip F which is slit and the parts f between the slits twisted so that they will lie at an angle to the flow of the moving fluid. The latter is thereby caused to take a tortuous passage and prevented from forming stream lines during its passage in contact with or in proximity to the heat transmitting surface. Three or more such ribbons may be used, the segments f being then staggered in relation to those of an adjacent ribbon. The segments may be twisted at an angle to the general path of the fluid flow and also to each other and further, also offset relatively to each other. The core or cores may be inserted in tubular or plate apparatus.

Abstract: 1,100,566. Clutch/brake control. INTEGRATED ELECTRONICS CORPORATION. 18 March, 1965, No. 11445/65. Heading F2L. [Also in Division B5] The control circuit of a machine which performs a repetitive process includes a plurality of switch-actuating sensing devices and shutdown means controlled thereby in such a way as to become operative at a predetermined point in the machine cycle. The control circuit, Fig. 1, is energized by manual operation of a switch 70 to energize relay 30 and the " go " lamp 36. The switch 20 is actuated to lock the relay 30, de-energize " stop " lamp 32 and to connect the main clutch of the machine. If in the ensuing cycle detecting switch elements 111, 111a, 111b are operated by the presence of work-pieces at particular machine stations the relays 40, 40a, 40b are energized and locked-in so that when the cam 83 subsequently opens the switch 82 the relay 30 remains energized. Lamps 47, 47a, 47b are energized with the relays 40, 40a, 40b, which are de-energized later when cam 53 momentarily opens switch 50 so that the succeeding cycle starts. If, however, one of the detecting switches 111, 111a, 111b is not closed the corresponding relay 40, 40a, 40b is not energized so that on opening of the switch 82 the relay 30 is de-energized to return the switch 20 to its initial position disconnecting the main clutch and applying the main brake. By adjusting the cam 83 the point in the cycle at which the machine is stopped can be varied. The finished work-pieces fall into a bin 65 which when full interconnects contact feelers 62, 120 to energize relay 60 and its lamp 67 so that on the next opening of the switch 80 by the cam 83 the relay 30 is de-energized to stop the machine. A detecting switch element may be associated with the stock supply and other detecting switches may be provided.

In the cyclic manufacture of coal water gas the hot coal water gas is passed from a carburetter through a distillation retort of a carbonization chamber. As shown during the " run " steam passes through valve 24, is superheated by passing over the hot chequered brickwork 11 in superheater 3 and enters generator 1 through pipe 25 and non-return valve 26. The steam forms blue water gas in shaft 10 and carbonizes the coal in distillation retort 9. The coal gas, blue water gas, and tar vapours pass through valve 23 to carburetter 2 where the tar vapours are cracked into oil gas. The coal water gas at a temperature of 750-800‹ C. passes through pipe 27 into the coal in retort 12 of carbonization chamber 4 to effect carbonization at about 650‹ C., the mixed gases finally being cleaned and cooled in wash-box 6 and condenser 7. Some of the cooled gas is supplied by booster 28 through pipe 29 to cool the coke in zone 13, the gas then mixing with the hot coal water gas to effect carbonization in retort 12. The semi-coke produced slips through shoot 30 into a container or a water-filled pit. During the "blow" air is forced by fan 8 through shaft 10, annular space 18 around retort 9, and through carburetter 2 and superheater 3 into the annular space 21 around retort 12 of chamber 4. It then passes through a dust collector 5 and stack 22 into the open air. Secondary air passes through valves 19 and 20 during the " blow." A waste heat boiler may be arranged between the retort 12 and dust collector 5, and the annular space 21 may be filled with chequered brickwork to retain the heat.
