Abstract: 271,501. British Thomson-Houston Co., Ltd., (Assignees of Chapman, V. J.). May 22, 1926, [Convention date]. Uniting by fusion.-In fusion welding by an electric arc or gas torch in which the work and source of heat are moved relatively to one another and in which the source of heat is oscillated across the joint, the source of heat is moved relatively slowly across the centre of the line of the joint and relatively rapidly at points distant from the centre line e.g. as shown at 44, Fig. 5, in order to increase the penetration of the work and prevent the formation of a weld concave at the centre and piled up at the edges. A metallic electrode 1 is fed through guide tubes 9, 10, terminal block 11 and contact nozzle 12 on a head 4 carried by a standard 5 which is mounted on a carriage 6 traversed with relation to the seam 3 to be welded. The electrode is fed by rolls rotated by change speed gearing from a motor 7. The welding head is adjustable laterally of the seam by a hand wheel 13 and the pressure of the rolls is adjusted by a hand wheel 14. The tube 10 is pivoted at 15 and is connected by a link 20 and adjustable clamps 18, 19 to a rod 21 to which a shaft 23 is secured by an adjustable clamp 22. The shaft is mounted in an elongated bearing tube 24 carried by the head and has a slotted upper end in which is pinned an arm 25 provided with a strip of insulating material 30 carrying a cam follower 32. This follower, which has an oil cup 33, co-operates with and lubricates a cam 34 on the shaft of one of the feed rolls, so as to oscillate the electrode across the joint, the follower being held in contact with the cam by an adjustable spring 36. To vary the amplitude of the oscillations, the set-screws securing the clamps 18, 19, 22 are released and the clamps adjusted with respect to the shaft 23 and tube 10.

Title: Improvements relating to digital dividing apparatus
Inventor: ROBINSON NIGEL DAVID
IPC: H03M7/12
Filed: 1957-04-30
Abstract: 892,622. Dividing apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. April 24, 1958 [April 30, 1957], No. 13795/57. Class 106 (1). Division of a binary number by a number of the form, for example, 1Œ2<SP>n</SP> is effected by feeding the dividend in serial form to a subtracting or adding circuit as the minuend or addend and feeding the output of the circuit to the subtrahend or augend input through a delay line providing a delay of n digits, the operation depending on the relation p#2<SP>n</SP> q - r = q, where p is the dividend, q the quotient and r the remainder. Fig. 2 shows apparatus for dividing a number of 36 digits P 0 , P 1  . . . P 35  (in order of increasing significance) by 10, i.e. 5 x 2, in two minor cycle divisions MC1 and MC2; in the first the number passes from the dividend input 7 through subtraction circuit 1, the first three digits P 0 , P 1 , P 2  passing through from A to D unchanged (due to 2-digit delay network 5 and inhibiting gate G4; the timing of pulses applied to devices such as G4 is indicated by the appropriate tick numbers t0-t35 in the appropriate minor cycles). The first digit P 0  is stored in two-state device 10 as the remainder after division by 2, to be subsequently combined with the remainder obtained after division by five, while subsequent output digits q 1 -q 32  are fed back to subtrahend input B effectively multiplied by 4 by delay unit 5 so that at output D appears a 32-digit partial quotient followed by a 3-digit remainder - q 35 2<SP>34</SP> + q 34 2<SP>33</SP> + q 33 2<SP>32</SP>. The remainder is passed by gates G10-G12 to twostate stores 11, 12 and 13 and by means of decoder 15 and recoder 16 converted to the smallest non-negatiye remainder modulo 5 on outputs 18 1-3 . The quotient obtained in this first division is not used. In the second minor cycle MC2, the 35 digit quotient of the division by two which has been passing through the register 9 via gate G2 is re-applied to the subtraction circuit 1; this time the remainder obtained as above described is subtracted from it by applying pulses to gates G13-G15 which apply the first two digits to input B and the third to the second subtrahend input C (this is necessary as it may be simultaneous with a subtraction pulse returned to input B through delay unit 5). The output at D thus represents the true quotient and is gated to register 9 by gate G5, and the remainder passes to register 19 where it is combined with the remainder of the ¸ 2 operation. Fig. 3, not shown, illustrates division by 12 in a generally similar manner except that unit 5 provides a delay of 1 digit to divide by 3, and that initial division is by four to give a twodigit remainder in a store corresponding to 10. It is stated that division by 7 may be effected by a similar method, by applying to two separate subtrahend inputs of a subtraction circuit the output delayed by two and one " tick " periods respectively.

Title: Improvements in the distribution and conveying of pieces of extruded plastic materials
IPC: A01J21/02
Filed: 1944-07-26
Abstract: 595,253. Cutting and delivering extruded material. STONESTREET, G. A., and SAIT, H. R. July 26, 1944, No. 14309. [Class 87 (ii) ] Pieces of plastic material are produced by a chain cutter 21 in combination with an extrusion head 15, the extrusion head being reciprocated transversely to the direction of extrusion just above a conveyer 29 so that the pieces fall in transverse lines across the conveyer. The plastic material is forced through the flexible tube 12 to the water-jacketed nozzle 14 which is mounted on the extrusion head 15 which slides on guide bars 17, 22. The endless chain cutting mechanism 21 described in Specification 595,252 is used to cut pieces off the extruded column. A finger 35 having a downwardly projecting roller 36 engages one side of a chain 37 driven by sprockets. At the end 'of the transverse movement of the extrusion head the roller 36 strikes a bar 39 and the finger is shifted out of engagement with the chain on one side and pushed into engagement with the other so that the motion of the extrusion head is reversed. The movement of the conveyer 29 may be intermittent, moving forward by one step each time a row of pieces is completed. In this case the driving sprocket of the conveyer may be secured to a ratchet wheel engaged by a reciprocating pawl, the pawl being actuated by, e.g., the electro-hydraulic " thruster " described in Specification 363,137, [Group X]. The electrical circuit of the thruster is completed at the end of each transverse movement of the extrusion head by the switches 40 which are closed by the rollers 41 mounted on rigid bars 42. Instead of a single conveyer 29 a group of parallel conveyers may be used and the extrusion head may be moved intermittently from one to the next. When the movement of the conveyer is continuous the extrusion head may be mounted on a central vertical axis and slewed round in a horizontal plane so that the row of pieces is deposited across the conveyer at right angles to the direction of travel.
