Title: Method and apparatus for producing carbonaceous materials for electrodes
Inventor: BODLAENDER HANS W
IPC: B02C17/18
Filed: 1957-07-02
Abstract: 812,320. Ball mills; screening apparatus. KENNEDY VAN SAUN MFG. & ENG. CORPORATION. July 2, 1957, No. 20855/57. Classes 59 and 117 A method of producing carbonaceous material for electrodes comprises the steps of subjecting raw unground carbonaceous material to a grinding operation in a single grinding zone to produce finely ground carbonaceous aggregate, air-sweeping the grinding zone with an air stream to selectively remove therefrom the finely ground carbonaceous material, selectively removing the coarsely ground aggregate carbonaceous material from the grinding zone, separating the finely ground carbonaceous material from the air stream, and mixing the coarsely ground aggregate and finely ground carbonaceous materials to produce a mixture suitable for making electrodes. Apparatus for carrying out the method comprises a rotatable cylindrical ball mill drum 12, Fig. 1, to which raw carbonaceous material and air are supplied through an inlet 24, the discharge end of the mill being provided with a shoot 26 through which a stream of air and finely ground carbonaceous material is drawn and with a duct 28 through which the coarsely ground carbonaceous material is discharged. The stream of air and finely ground material is drawn from the shoot 26 by means of a fan 32 and delivered in succession to cyclone separators 35, 37, the fine materials from which are delivered through ducts 39, 40 into a common duct 41 and then into a mixer 42 to which are also delivered the coarse material discharged through the duct 28 by means of a motor-driven screw conveyer 43, and hot pitch or tar from a container 45. The electrode paste formed in the mixer 42 is delivered to electrode moulds by means of a motordriven screw conveyer 47. The coarsely ground material is separated from the finely ground material by means of a screen 50, Fig. 2, having on the outlet side thereof three equally-spaced curved lifters 54 each associated with a web 54 and a pivotally-mounted shoot 68 by means of which the coarsely-ground material is delivered to a cylindrical member 64 provided with helical fins 65 and thence to the duct 28. The member 64 is supported by brackets secured to the helical fins 63 of a member 61, the fins 63 returning to the mill drum any coarse material separated out in the delivery shoot 26. The shoots 68 are simultaneously adjusted and set, according to the amount of coarselyground material required, bymeans of a control 30 comprising a rotatable rod 72 movable longitudinally by means of a pivotally-mounted lever 91 which is locked in the desired position by means of a handle 107. The casing of the shoot 26 has welded thereto the plate 82 of a manhole cover unit, the plate 82 carrying a pair of normally-closed inspection tubes 110 (not shown). The trunnion 16 is provided with a flange 60 to which a ring driving gear is secured.

Title: Knot adjusting arrangement for a coil spring feed apparatus
IPC: B21F27/16
Filed: 1972-05-05
Abstract: 1391201 Orientating and conveying articles SPUHL AG 5 May 1972 [22 May 1971] 20962/72 Heading B8A In apparatus for feeding an array of helical wire springs, for example to a machine for manufacturing spring mattresses, the springs are orientated such that their wire ends or "knots" 7 of their end coils 8 are aligned, as shown in Fig. 2, by turning mechanisms 9-11. These mechanisms co-operate with two endless belts 1 which feed the springs step-by-step from a spring manufacturing apparatus (not shown). Assuming the springs are fed with their knots in position 7<SP>1</SP>, pusher 12 of the mechanism 9 moves to a position determined by a stop 14 and the knots of the seven springs to the left of Fig. 2 are aligned with an axis m-m. The knot of the spring 8n which preceded the other springs is, due to removal of the stop 14, caused to move to a position 7 2 . The mechanism 10, by means of a pivoting arm 17, then moves the knot to a position 7 3 , after which the mechanism 11 moves the knot to position 7 4  in alignment with the other knots but with its spring 8n rotated through 180 degrees relative to the other springs. Damage to covers for the springs is avoided by such positioning of the springs. To improve the accuracy with which the springs are rotated, pairs of oppositely located mechanisms 9, 10, 11 may be provided. The mechanism 10 includes a double-acting pneumatic cylinder 53 which, by means of a reciprocating member 50 causes the knotengaging arm 17 to pivot. A stop 16 for engagement with the springs when a knot 7 is being acted on by the arm 17 is movable by a cylinder (42) and a pivotable lever (31), Fig. 5 (not shown).

Abstract: 1426726 Fluid-pressure servomotor systems C A V Ltd 30 April 1973 [5 May 1972] 21014/72 Heading G3P [Also in Division F1] A fuel injection pump is provided with an automatic timing device comprising a piston 18 movable to adjust the timing, a servovalve 22 slidable in an axial bore 20 within the piston 18 and operable to control the position of the piston 18, a passage 23 for supplying speed dependent fluid-pressure to one end of the servovalve, and springs 24, 25 for opposing movement of the valve caused by the fluid-pressure. The piston 18 is provided with a peg 19 for rotating the cam ring 16 of the rotary distributer type pump shown. In operation, the increasing pressure applied to the valve, as engine speed increases, causes the uncovering of a port 28 whereby liquid flows through a passage 30 to cause rightward timing advancing movement of the piston 18 until the port 28 is again covered. Initially movement of the valve is resisted by the spring 24, but when the clearance R is taken up the movement is resisted by the stronger spring 25 until a stop member 26 abuts a plug 27.

Title: Improvements in or relating to electrical non-linear resistance devices
Inventor: GARDNER ERLE
IPC: G06F7/501
Filed: 1959-06-19
Abstract: 900,548. Electronic adders. GENERAL ELECTRIC CO. Ltd. Sept. 19, 1960 [June 19, 1959], No. 21126/59. Class 106 (1). [Also in Groups XXXVI and XL (c)] An electrical non-linear resistance device consists of a disc of silicon carbide with electrodes 1, 2, 3 on one side (Fig. 1) and 7, 8, 9, 10 (Fig. 2) on the other. The electrodes 1, 2, 3 are all opposite electrode 6 and two of them are opposite electrodes 8, 9 and 10. The electrodes may be of gold or brass. The law of the silicon carbide is i=kv<SP>n</SP>, where n is greater than 1 and preferably greater than 3. Fig. 4 shows a representation of a device in which the electrodes retain their own references and the resistive material between pairs of electrodes 1 and 8, for example, is indicated by (1, 8). The device operates as a three gate between electrodes 1, 2, 3 and 6, that is unless a pulse is applied simultaneously to all of electrodes 1, 2 and 3, electrode 6 remains at earth potential and transistor 15 remains conducting because of the positive emitter bias. Application of three pulses at once blocks the transistor giving a collector output. Similarly, electrodes 8, 9 and 10 are so connected to electrodes 1, 2 and 3 to act as two gates. Half adder (Figs. 5 and 6).-Input pulses are applied to lines 17, 18 and 19 (Fig. 5) and the silicon carbide device as described above constitutes two gates 22, 23, 24 and three gates 30. The outputs of all the two gates are connected to a one gate 25 which is connected to a " carry " terminal 26 and to a negatory two gate 27, the other supply to which is from a one gate 21. The output of the two-gates 27 feeds through one-gate 28 to a sum terminal 29 and this onegate is also fed from three gate 20. The arrangement is that three pulses feed outputs to both the sum and carry terminals, two pulses to the carry only and one pulse to the sum only. Fig. 6 shows a circuit diagram of the arrangement. Pulses may be applied to one or more of terminals 17, 18, 19. The silicon carbide connected to terminal 6 constitutes the threegate feeding a discriminator 44 and amplifier 46 and finally, through a one-gate comprising rectifier 41 and resistor 42 and corresponding to the one-gate 28 of Fig. 5, the sum terminal 29. Rectifier 36 and resistor 37 are all onegates so that a pulse applied to any of terminals 17, 18, 19 feeds a pulse to negatory two-gate 27 which is not able to reach sum terminal 29 unless a negative signal is received from onegate 25 following two-gates 8, 9 and 10 in the silicon carbide device. Output pulses from one-gate 25 are amplified at 23 and applied to " carry " terminal 26. They are also inverted and applied to gate 27 so that one pulse cannot register at " sum " terminal 29.

Title: Improvements relating to automatic voltage control means for use with electrostatic precipitators
Inventor: MILNER MAX
IPC: B03C3/68
Filed: 1959-06-23
Abstract: 891,010. Automatic control systems for electrostatic precipitators. FERRANTI Ltd. June 9, 1960 [June 23, 1959], No. 21416/59. Class 38 (4). The high voltage transformer of an electrostatic precipitator is supplied through a saturable reactor, the control winding of which is so energized as to raise the precipitator voltage steadily until a flashover occurs, whereupon the voltage drops to zero and then returns to a level lower than that at which the flashover occurred, rising steadily again thereafter. The control winding of the reactor 4 is energized by a pair of thyratrons 6, 7, the conduction of which is controlled by a D.C. bias applied to a grid phase-shifter 9. This bias is normally obtained by charging a capacitor 14 through a resistor 12 from an auxiliary D.C. source, so that the precipitator voltage rises as the voltage across capacitor 14 rises, until a flashover occurs. This applies a pulse, through capacitor 24, to render conducting two normally cut-off triodes 15, 16. Triode 16 has a separate H.T. supply 18 and resistor 19 is of a high value, so that the potential of point B goes negative and cuts off the thyratrons 6, 7. Conduction of triode 15 slightly discharges capacitor 14, so that after the flashover the precipitator voltage resumes its rise from a slightly lower point. If several flashovers occur before the precipitator voltage is lowered, the triodes 15 and 16 conduct for a time which is proportional to the numbers of flashovers occurring and capacitor 14 discharges accordingly so that the precipitator voltage eventually resumes its rise from a proportionally lower point.

Filed: 1945-08-22
Abstract: 604,459. Electric selectors. STROMBERG-CARLSON CO. Aug. 22, 1945, No. 21444. Convention date, April 21. [Class 40 (iv)] A selector switch comprises a ball-race unit 37 which is reciprocated under control of the solenoids 14 in response to impulses, cam elements 62 projecting into the ball-race serving to advance a ball 47 (Fig. 7) along the race stepby-step. At each step the ball raises the cooperating cam element to close one of a set of contacts 8, 9 by means of a pusher 10. Construction. - The solenoids 14 comprising the driving magnet are mounted in a block 15 which is screwed to the cam assembly support 20, the armature 25 being pivoted on knife edges 17 and 22 on the block and support respectively and being urged away from the solenoids by springs 35. The opposite face of the block is provided with hardened inserts 36 having V-notches serving as bearings about which the ball-race unit 37 oscillates, knife edges 40 on the inturned end portions thereof engaging the V-notches. The ball-race 44 of flattened elliptical outline has openings 45, 46 in the upper and lower plates 42, 43, the latter also being provided with a knife edge 43a co-operating with the recess 48 in one end of a toggle link 49, the other end of which engages a notch 51 in the armature. The cam assemblies each comprise two plates 57, 59 having holes through which the cams 63 and 62 project respectively. A switch 75 is fitted to the block 15 and is actuated by a push-rod 79 under control of the armature 25. Operation.-With the switch 75 closed, energization of the solenoids 14 by an incoming impulse results in the ball-race moving downwards under the action of return spring 85. At the end of the impulse, springs 35 restore the armature and raise the ball-race. On the downward movement of the ball-race, the ball 47 moves down with it followed by the cam 62a to the full extent of its movement, indicated by the dotted lines (Fig. 7), whereupon the ball depresses cam 62b and is itself moved along the ball-race thereby, passing under cam 62c into contact with the side of 62d. Cam 62c is depressed in a similar manner during the next upward movement of the ball-race and the ball is moved over cam 62d into contact with 62e. The upper cams are each associated with a cylindrical stem 63 engaging a pusher 10 so that the sets of springs 8, 9 are actuated in turn, the set corresponding to the digit received remaining operated at the end of the impulse train. Automatic hunting is obtained by connecting the switch 75 in the solenoid circuit, each attraction of the armature serving to interrupt the energizing circuit. Double-capacity switch.-In a modification (Fig. 8, not shown), both the upper and lower cams are effective in operating spring sets.
