Applying liquids to work.-Relates to preparing welting for the inseaming operation, and consists in tempering it on one edge by dipping this edge into water or other liquid e.g., just prior to its being fed to the inseam stitching machine. A kink-removing device is provided prior to the tempering machine. Water in a tank 12 is maintained at a constant level from an inverted bottle 16 the mouth of which is sup ported at an adjustable height, the water flowing into the tank by a passage of inverted V-shape at its top. Posts 13, 15 at the sides of the tank support a dipping device through which the welt is fed. Alternative forms of dipping devices are described, an adjustable form, Fig. 1, comprising a body 34 carrying pins 36, 38 at right angles. Members 40, 42, longitudinally adjustable along these pins, together form a guide-way for the welting, the members being kept in alignment by a flat face 44 on the member 40 and a fork 45 on the member 42 engaging a tongue 46 on the member 40. The body 34 and member 40 are recessed to prevent water creeping up the grain side of the welting by capiliary action, the corner 54 of the recess being at the water level. The body 34 is adjustable along a slot 50 curved about the corner 54, the slot being formed in an arm 14 guided on the post 15 and carried by a sleeve 20 adjustable longitudinally of the post 13. The sleeve normally rests on adjustable nuts 32, but may be raised at the end of the day by a handle 28 provided with a crank linked to the sleeve. The handle is pivoted to a collar 24 adjustable vertically on the post 13. The kink removing device comprises a pair of brackets 94 forming edge guides for the welting and carrying a pair of substantially triangular plates 96 forming side guides. A ring 98 is secured over the triangular plates, which engages the edges of any kinked portion of the strip. From this device the welting passes over a roll 92 and through an aperture formed by lugs on the tank supporting a rod 58. The roll 92 and the upper and lower sides of the aperture are inclined to correspond with the inclination of the strip at the welter point. In a modification, Fig. 7, a disc so formed with four welt guiding apertures of different sizes is clamped in a ring 82 carried by the sleeve 20, the aperture to be used being positioned at the bottom before the clamping ring is tightened on the disc. The apparatus may be mounted on a plate 68, Fig. 5, secured by hook bolts 70 to the edge 66 of the work table of an inseam sewing machine, the tank 12 and water bottle being supported on the reduced upper ends of posts 72 on the plate 68.

A trip - free, snap - action switch for a motor starter comprises movable contacts mounted on a pair of bridges 42, urged to contact-closed position by springs 48, sliding on an insulating contact carrier 46, itself guided in groove 18 and slots 38 in the base 10. A contact operating lever 82 has a finger 84 slidable in slots 20 in the base and engaged with slot 50 in the contact carrier 46, the lever being actuated manually by an over-centre spring action comprising a lever 52 and a spring 76 secured to the bridge of a support 70, pivoted to lever 52 by a pin 74, and to a hole 78 in a yoke 62 which is pivoted between trunnions 56 of the lever 52 by a pin 64, a slot 80 allowing yoke 62 to swing about pin 74. As lever 52 is swung from " on " to " off " (Fig. 2), pin 64 moves anti-clockwise about pivot 74 until pin 64, hole 78, and spring 76 are in alignment, and the spring support 70 initially held against a groove 32, and when alignment position is passed, the legs of the spring support 70 will contact lever 82 and swing it to the position shown in Fig. 2, finger 84 thus depressing the contact carrier 46 and opening the contacts. On overload, the heater coil of a thermal release assembly melts a blob of solder allowing a ratchet 106 to rotate and release a spring finger of an arm 102 forming part of lever 90 pivoted on pin 74 which then rotates under influence of a spring 98, the lever 102 engaging a bar 88 on lever 82 and thus opening the contacts (Fig. 4). To reset the switch, the lever 52 is swung from the " on " (Fig. 4) to the " off " position, which causes the lower left-hand edge of the lever to engage the bridge of lever 90 and swing it anticlockwise to carry arm 102 to the position of Fig. 2 so that finger 104 again engages with ratchet 106.

Abstract: 993,494. Electron beam apparatus. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 5, 1963 [July 12, 1962], No. 26882/62. Heading H1D. An electron gun includes a cathode 1, an anode 2, and a strip transmission line formed by an apertured strip inner conductor 4, which acts as a control electrode, and an apertured outer conductor extending transversely across the path between the cathode and anode. The gun is controlled by applying to the transmission line positive pulses of sufficient amplitude to overcome a negative bias applied to the inner conductor 4, which may have a grid 3 mounted in the aperture. The outer conductor comprises upper and lower portions 5 and 6 and is coupled to the inner conductor through a condenser 7 and an optional resistor 8 which, if present, has the same impedance as the transmission line and absorbs the control pulses. If the resistor 8 is omitted a sharp-fronted incident pulse is reflected with a change of polarity to provide a resultant control pulse the duraton of which (e.g. 10<SP>-3</SP> Á sec.) is largely independent of that of the incident pulse. The aperture in the upper portion 5 of the outer conductor is shaped to provide a beam forming electrode and may be provided with a screen grid 9. A mounting arrangement is described (Fig. 5, not shown) in which the electron gun is supported from a plate which may be the end plate of the vacuum chamber of an electron accelerator. Specification 697,823 is referred to.
