Title: Fusion Welding Methods.
Inventor: MARSDEN ROY
IPC: B23K9/007
Filed: 1967-01-18
Abstract: 1,170,113. Welding by fusion. SUPERHEATER CO. Ltd. 18 Jan., 1967, No. 2607/67. Heading B3R. Abutting members are joined by forming discrete fusion welds between localized regions of the abutting members to produce a continuous joint composed of overlapping discrete welds. The welds may be formed by one or more argon shielded tungsten electrode arc torches. The are is started by a high frequency discharge. Each weld is timed by a timer T1, Fig. 1, which at the end of the welding pulse puts a resistance R1 in circuit to reduce the welding current and sets a timer T2. When timer T2 times out it sets a timer T3 and starts a motor producing relative movement between the torch and the work. When timer T3 times out the motor is stopped and a further weld is started. The amplitude and/or duration of each welding pulse may be reduced after a number of welds have been made to limit heat build-up in the work. Such a method may be used with an internal rotary welding gun to produce the welds 1, 2, 3 . . . Fig. 4, between a tube and a tube plate, or to weld plates or tubes end-to-end. Consecutive welds may be spaced and intervening welds formed subsequently by the same or a different welding torch. Groups of spaced welds may be made simultaneously.

Filed: 1973-01-22
Abstract: 1420106 Television NIPPON STEEL CORP and HAMAMATSU TV CO Ltd 22 Jan 1973 3238/73 Heading H4F Data from a plurality of channels is multiplexed with a television video signal and recorded on a video tape by converting an analogue data signal from each channel into a 10-bit digital signal these bits being recorded sequentially during 10 line scan periods of the video signal one bit in a blanked portion of the video signal after each horizontal sync pulse. After multiplexing a 10-bit digital signal from one channel with the video signal a parity bit pulse and then a word bit pulse are multiplexed with the video signal after the next two horizontal sync pulses. An analogue data signal from the next channel is them similarly multiplexed with the video signal during 12 line periods, i.e. 10-bit digital signal, parity bit pulse and word bit pulse. The sequential multiplexing of data from all the selected channels from which it is desired that data should be recorded, the other channels being skipped over, is similarly effected and then a group bit pulse is multiplexed with the video signal in the same blanked portion of the video signal as the last word bit pulse from the last channel. The multiplexing sequence is then repeated starting at the first channel. In addition a channel command pulse of substantially line duration is included in the vertical blanking period followed in the next line period by pulses signifying by their position the channels from which data has been selected. All the bit pulses are recorded at time #t 1 , after the horizontal sync pulses except the group bit pulses which are recorded at time #t 2  after the horizontal sync pulses. The complete signal may be displayed as shown in Fig. 4. The data signals recorded may signify the time of generation of the video signals.

Title: Improvements in or relating to labelling machines
Inventor: HOWARD FAIREST DEREK
IPC: B65C9/08
Filed: 1962-01-30
Abstract: 954,121. Labelling machines. MORGAN FAIREST Ltd. Jan. 9, 1963 [Jan. 30, 1962], No. 3386/62. Heading B8F. A labelling machine for applying neck and/or body labels comprises a rectilinear means or, as shown, a turntable 5 carrying bottles 3 held in arms 6, a label stack 30, a pick-up turret 26, gumming means 29, a transfer arm 32 and wiper flaps 17, 18 in the path of the bottle. A transfer finger 35 on the transfer arm 32 carries a label from the pick-up turret 26 to the two pairs of wiper flaps 17, 18 and is so orientated as to keep the label parallel to the face from which it was taken. Label transfer and gumming means.-A reciprocating gum applying mechanism 29 applies gum to the side faces 27 of the pick-up turret 26, the faces 27 being separated by a gap 28. The turret (Fig. 1) is indexed 45 degrees and the gummed face receives a label from a reciprocating label stack 30. The turret is again indexed 45 degrees and the transfer finger 35, holding the label by suction, passes through the hole 28, taking the label. The label is maintained parallel to the plane in which it was when it was removed from the turret face which is also parallel to the flaps and the path of the finger takes it through the gap in a face perpendicular to the plane of the label so that the label passes through without contacting the sides of the gap 28. The finger then passes through the flaps 17, 18 and the ungummed faces of the labels are held thereon by suction as they are released from the finger 35. The turret can be indexed while the transfer finger is either inside or outside the turret. The wiper flaps are spring-loaded to return to their central position and the body flaps are hinged vertically while the neck flaps have vertical and horizontal hinges to enable the flap to follow the shape of the bottle neck. Conveyer means.-The bottles 3 are suitably spaced by a star wheel 3 and moved on to a table 5 on which they are gripped by presser heads 8, at the ends of arms 6. The heads are forced upwardly by springs 9 and are moved down into contact with the bottle as roller 10 engages a cam rail 11. The bottle is moved through the wiper flaps 17, 18 and through the brushes 14 before being removed by the starwheel 15. In modifications to the turret 26 the octagonal turret may have apertured faces alternating with open sides and by indexed through 45 degrees both while the transfer finger is inside and outside the turret. In another modification (Fig. 8) a square turret rotates about an axis perpendicular to that of the transfer arm and has two apertured sides opposite each other, the other two sides being open and having one open end through which the label leaves, the turret indexing through 180 degrees while the finger is outside the turret. The gumming mechanism 29A for this modification consists of rollers (Fig. 5). More than one transfer arm can be used.
