Filed: 1976-07-30
Abstract: 1528278 Pattern followers GRIESHEIM GmbH 30 July 1976 [2 Aug 1975] 31868/76 Addition to 1465795 Heading G1A The pattern follower control system for control of workpiece cutting, e.g. using a parting knife, laser, plasma torch or oxy-fuel gas torch, as described in Specification 1465795 is modified so as to deal with the situation where two deceleration marks lie close together on the workpiece pattern. Photo-resistance 24 detects the deceleration marks and activates monostable multi-vibrator 27 for a period t 1 , via amplifier 26, whose output passes via OR gate 29 to switch 30 connected to relay coil 32 to slow down the sensor and cutter (not shown). At the same time, monostable 36 is triggered so that a different photo-cell pair is used for sensing. If a second deceleration mark is detected before time t 1  has expired, AND gate 81 activates monostable 82 whose output passes to OR gate 29. Thus slow speed movement continues.

Title: Improvements relating to electric arc stud welding
Inventor: AINSWORTH ARTHUR RATCLIFFE
IPC: B23K9/20
Filed: 1956-10-23
Abstract: 823,614. Welding by pressure. CROMPTON PARKINSON Ltd. Oct. 10, 1957 [Oct. 23, 1956; March 14, 1957], Nos. 32308/56 and 8478/57. Class 83 (4). [Also in Group XXXV] In electric arc stud welding equipment in which a solenoid retracts a stud from a workpiece to strike a pilot arc the current in which is limited by a series impedance subsequently short-circuited by a main contactor to apply the full welding current, the main contactor is energized either directly or indirectly by the voltage set up across the pilot arc. Operation of a push-button PB, Fig. 1, energizes the solenoid 11 to retract the stud 1 and connects the stud 1 and the workpiece 2 across the supply 3, 4 in series with the impedance 17 to strike the pilot arc. The main contactor MC whose coil 20 is connected between the stud 1 and the workpiece 2 operates to short-circuit the impedance 17 and to disconnect a relay R. After a delay due to condenser C, relay R falls back to disconnect the solenoid 11, whereupon the stud 1 is welded to the workpiece 2 and the collapse of the welding arc de-energizes the coil 20. In a modification (Fig. 2, not shown) operation of the push button PB energizes a relay only if the stud is engaging the workpiece. This relay energizes the solenoid and connects the coil of the main contactor between the stud and the workpiece. A pneumatic timer is used. In a further modification, actuation of the push button PB, Fig. 3, brings up a relay S if the stud 1 is contacting the workpiece 2 and energizes one coil 50 of the solenoid to retract the stud 1, the coil 50 also acting as the limiting impedance. Relay S short-circuits contacts 54, 55 of the push button PB. When the push button PB is released, the pilot arc voltage energizes a relay T to connect up the coil 20 of the main contactor MC which short-circuits the coil 50 to apply full welding current and places the second coil 51 of the solenoid in circuit. After a delay a pneumatic timer actuates contacts 62, 60, contact 62 short-circuits the solenoid coil 51 to make the weld and contact 60 disconnects relay T which slowly releases to deenergize the main contactor coil 20 even if the stud has stuck in the retracted position. Specifications 673,743 and 764,764 are referred to.

Abstract: 1,260,011. Welding by fusion. MOSKOVSKY ORDENA LENINA ENERGETICHESKY INSTITUT. 26 June, 1969, No. 32311/69. Heading B3R. In consumable wire electrode arc-welding or deposition, of metals such as aluminium and titanium, the arc is stabilized and parasitic arcing is eliminated by shielding current carrying parts of one of the electrodes (e.g. the wire) by a metal envelope having an electrical charge of the polarity of the charge of the other electrode (e.g. the workpiece). As shown, a workpiece 3 is mounted on a movable table in a vacuum chamber 1. The table and chamber are connected to negative. The electrode wire 5, fed by a head 4, is supplied through a tip 6 the electrical input thereto being connected to positive and insulated from the chamber by a sealing device 7. A metalshielding envelope 8 surrounding the wire and tip is connected to an additional, low-power, current source such that the envelope charge polarity is that of the workpiece. The voltage of the additional source may be varied. In an alternative embodiment, the additional source is dispensed with, the envelope, on arc striking, storing a charge of workpiece polarity.

Abstract: 1,253,467. Velocity-modulated tubes. VARIAN ASSOCIATES. 30 June, 1969, No. 32997/69. Heading H1D. A microwave tube includes a centipede slowwave structure-i.e. a coupled resonator structure formed by a sequence of spaced discs 14, Fig. 2, axially spaced along a conductive tube, each disc being centrally apertured at 16 to permit passage of the electron beam, and having an array of peripherally spaced, radially directed, leg portions 18 with adjacent legs of S- shape and reverse S-shape, respectively-in which the legs are of constant width over their lengths, as shown at 18 in Fig. 4, in contrast to the prior art sector shape or indented sector shape shown at 18<SP>1</SP> in Fig. 4. The structure is mounted within a cooling jacket 19 having a helical coolant channel 21, the legs being clamped in position axially by the succession of conductive rings 24, and fixed circumferentially, with the legs of adjacent discs arranged interdigitally with respect to one another, by the insertion of the ends of the legs within spaced notches in retainer rings 22 (and see Fig. 3, not shown). At the output end of the structure, as shown in Fig. 2, the cavities are made of successively shorter axial length, to maintain synchronism between the wave and the electron beam, and S and reverse-S shapes are successively more flattened to raise the upper cut-off frequency and hence prevent band-edge oscillations by improving the impedance match between the centipede structure and the load. The internal diameter of the cavities are arranged to exhibit a corresponding progressive decrease, to compensate for the effect of the above changes on the low-frequency cut-off. The centipede structure may be severed and may be preceded by a stagger-tuned multi-cavity klystron section.

Abstract: 1409126 A stack of containers D I BARTOS 11 July 1973 [11 July 1972 10 May 1973] 33027/73 Heading B8C  A stack of a plurality of box- or jar-shaped containers 1, 2, each comprising a bottom tray 2 and a cover tray 1 formed of a top portion and a lateral rim depending from the top portion and partly surrounding the bottom tray, each container containing a filling in sterile condition, is characterized in that the superimposed containers are firmly forced against one another and held together in non-slip manner by two lengths of adhesive tape each of which extends from the top portion of the uppermost cover tray to the underside of the lowermost tray bottom, thereby to hold the containers in hermetically sealed condition. As shown in Fig. 1, a stack of four bottom trays 2, made, e.g., of substantially rigid plastics material, or glass, and each containing nutrient 4, such as blood agar, is engaged, under pressure, by their covers 1 to form air-tight seals, the entire stack being held under vertical compression by an adhesive tape loop 3, and preferably by a second loop 5 applied crosswise with respect to the first loop. More than two  loops may be employed, and the loops made, e.g., of high-tensile-strength, stretched plastics film or of paper, textiles, or plastics impregnated fabrics and provided on one face with a conventional pressure-sensitive adhesive, may be replaced by two separate parts which extend correspondingly down the sides of the stack. The loops, or strips, may either be adhered only to the rims of the covers, Fig. 1, or to the rims and also to the exposed surfaces of the bottom trays 4. Lateral displacement of the stack can be prevented, e.g. by providing the top covers 1 with upwardly protruding flanges 6 within which the bases of the associated bottom trays 2 are adapted to fit. Other well-known interfitting relationships are also described. An additional seal may be obtained by interposing between the upper edge of each bottom tray 2 and its cover tray 1 a thin layer of sterile sealing composition such as high-vacuum greases, soft waxes, resins, or plastics polymers. The upper edges 7 of the bottom trays 2 may be fluted at 7 and contain sealing compound, and the overlapping rims of the cover trays 1 may tightly engage the lateral wall of the associated bottom tray 2. The upper edge of the wall of each bottom tray 2 may be provided with a flange (8) which may either extend inwardly or outwardly or, in both of these directions, and may have a fluted upper edge (Figs. 6a-6c, not shown). The flanges may be replaced by upwardlyinclined lamellµ an example of which is shown in Fig. 7b. The bottom trays 2 may be divided into separate compartments by webs (10), Figs. 9a, 9b (not shown), for the sub-division of nutrient medium. The stack may be wrapped in a plastics bag heat-sealed at its ends.
