Title: Method and apparatus for forming clay sagger pins
IPC: B28B11/16
Filed: 1941-08-18
Abstract: 553,764. Moulding sagger pins. DEHN, F. B. (Industrial Ceramic Products, Inc.). Aug. 18, 1941, No. 10505. [Class 87 (ii)] A clay column is extruded through triangular openings 5 in a nozzle 4 on to a conveyer belt 6, a cutter 28 cuts strands from the column and a second cutter 29 cuts the strands into pins of uniform length. The two cutting operations take place while the clay lengths are moving in the same direction as the conveyer belt. The speed of extrusion is less than the speed of the belt, so that slippage occurs between the strands and the belt prior to the first cutting operation. When the strands have been cut from the column they move away from the cut end thereof. When the pins reach A they are removed by hand on to a transversely-disposed conveyer 71 which carries them through a tunnel drier kiln 3. The cutter 29 is continuously driven, in synchronism with the belt 6, by an electric motor 25, and comprises a knife 50 disposed transversely (or obliquely) of the belt, the knife being carried by a vertical plunger 35 which is intermittently depressed, against a spring 55, by a cam 59 acting on a rocking arm 56. When the plunger 35 descends, knurled feet 49 on the knife assembly engage the belt, the movement of the belt being thereby imparted to the knife assembly which slides forward along a guide pin 38 against a spring 40 ; during this sliding movement the knife descends through a slot in a stripper member 53 and cuts through the strands, the cut surfaces being normal to the longitudinal axis of the strands. When the plunger 35 ascends, the spring 40 returns the knife assembly to its initial position. Spring-pressed rollers 65 resist raising of the belt by the feet 49. The cutter 28 is, in general, similar in construction to the cutter 29, but its plunger is solenoidoperated under manual switch control, and it has a plate which presses the cut clay strands into engagement with the belt to make them move with the belt away from the column.

Filed: 1959-03-26
Abstract: 878,648. Valve pulse generating circuits. STANDARD TELEPHONES & CABLES Ltd. March 26, 1959 [April 3, 1957], No. 10588/59. Class 40(6) A control circuit for a gas discharge tube comprises a source of pulses connected to the control electrode and a delay line with one end short circuited and the other connected to the control electrode so that the pulses are inverted and delayed so as to reduce deionizing time. In the circuit shown, a pulse forming network is discharged when the gas tube 3 is triggered by a positive pulse from source 1. After the pulse forming network has discharged, a reflected negative pulse from the delay line 5 reaches the control electrode to reduce deionizing time. A filter 8 prevents a large positive pulse generated at the control electrode by the firing of the gas tube 3, from reaching the source 1.

Title: Improvements in or relating to welding machines
IPC: B23K11/31
Filed: 1929-04-06
Abstract: 309,196. Budd Wheel Co., (Assignees of Eksergian, C. L.). April 6, 1928, [Convention date]. Wheels.-In welding discs to the rims of wheels, a welding-machine is arranged in fixed juxtaposition to a work conveying path and the work is moved transversely from the path to and from the machine. The discs 12 are fed by reciprocating arms 11 along a track 10 from the last forming machine 14, so as to transfer them successively to a machine 15 for forming spuds 45<1> in the flanges, a machine 17 for assembling the rims and discs, and an electric welding machine 19 for welding the rims to the discs. The discs are lifted from the track and clamped against an abutment 65 on the machine 15 by a pneumatically operated cylinder 47 provided with a head 50 for fitting the centre of the disc and pins 49 for engaging holes 45 adjacent thereto. The flanges are thus inserted between a series of pairs of radial dies 46 which are operated by fluid pressure cylinders 51 to form the spuds. The flanges are then lowered to return the discs to the track. The track from the assembling machine to the welding machine is at a lower level and as the discs are transferred from the machine 15 they are pushed by a reciprocating head 18 into the rims 13. The assembled parts are then transferred to a movable section 10<1> of the track under the welding machine, the wheel with its track being lifted so that the flanges are inserted between a series of pairs of adjustable water-cooled radial electrodes 29, 31, the centre of the disc engaging an adjustable head 43 and the holes 45 passing over pins 44 thereon. This motion is effected by a spider 37 carried by a pneumatically operated piston 39, rods 41 and sockets 42 maintaining the radial alignment of the parts. The pairs of electrodes are mounted in cylinders 25 floatingly mounted in guides 24, and are each connected to a separate transformer. The electrodes 31 are actuated by pistons 26 retracted by springs and operated pneumatically. The fluid pressure is supplied to the actuating members through valves 60 controlled by cams 61 .. 64 on the timing shaft 61<1> of the fabricating line. The welding cylinders are controlled by the cam 61. The pressure is also communicated through a quick release pneumatic valve 57 to operate an electromagnetic relay 54 so as to put in the welding switch 53 after the electrodes have been pressed into contact with the work and to release it before they are disengaged therefrom. Reference has been directed by the Comptroller to Specification 305,097, [Class 83 (iv), Metals, working].

Title: Separating apparatus
IPC: B01D47/06
Filed: 1937-04-22
Abstract: 485,807. Centrifugal separators. TRIGGS, W. W. (Centrifix Corporation) April 22, 1937, No. 11505. [Class 23] Apparatus for separating entrained matter, such as oil or the like, from gases or vapours, consists of a casing 2 divided into two chambers by a partition 7 supporting a tangentially bladed centrifugal separator 8 which forms the only channel of communication between the two chambers. The inlet 5 is connected to the lower chamber and the outlet pipe 6 leads from the upper chamber, while the separator has upper and lower races for the separated entrained matter. The incoming gas with the entrained oil passes along the pipe 9 and meets a jet 16 of vapour such as steam from the nozzle 14 on the pipe 14a. The mixture passes through the tuyere element 11, which causes it to whirl in the main chamber on its way to the separator 8. The temperature is such that the oil is in liquid form while the steam remains in vapour form, and owing to the whirling motion some of the liquid particles, with any solids that may be present, are thrown against the casing wall, and drop to the bottom where a drain 10 is provided. The separator 8 has two end rings 8c, 8d, connected by overlapping blades 8a the spaces between these blades providing tangential entries for the whirling stream of gas and vapour. The blades are made of thin metal with stiffened outer edges, and the cross sectional area of the body portion of the separator is substantially double that of the outlet orifice 8h. A circumferential race 8x is arranged at the top of the separator and the inward extension of the top plate from this race forms a conical surface 8c<11>. A corresponding race 8y is formed at the bottom of the separator and the two races are connected by ducts 8m. The whirling material from the casing passes tangentially between the blades 8a, and the entrained particles are thrown outwards while the clean gas and vapour pass upwards to the outlet 6. The particles collect in the races 8x, 8y and pass by the drain pipe 8t to the vessel 9x from which they overflow to the discharge drain 10. The apparatus may be modified to permit the inlet and outlet to be placed opposite each other.
