Abstract: 860,167. Gripper shuttle looms. VYZKUMNY USTAV TVARECICH STROJU A TECHNOLOGIE TVARENI. Sept. 9, 1957, No. 28366/57. Class 142(2) A double-ended gripper shuttle consists of a tubular body 6, each end 3 of which forms one jaw of a gripper; the other jaws consist of heads 22, 22a, carried by tubular stems 2 on which are fixed flanges 5 loaded by springs 4 tending to close the jaws. During beat-up, a rod 1 rides on to a fixed ramp 9, causing a flange 7 to push open the jaw 22; suction applied at a port A in the shuttle box 8 draws the end of a weft supply 10 into the space between the jaws 3, 22; as the slay recedes, the rod 1 rides off the ramp 9, whereupon the jaws close to grip the weft. The shuttle is picked by air pressure applied at a port B in the shuttle box. Forming selvedges. As the shuttle enters the shed, the end of the preceding pick P, which is still held by the jaw 22a, is turned into the shed to form a tucked-in selvedge, and slides out of the jaws as the shuttle continues its movement. Weft stop motion. The heads 22, 22a are insulated from the stems 2 so that when weft is present there is no circuit from the shuttle box 8 through the body 6 to the heads; if weft is not gripped between a head and the co-operating jaw 3, a circuit is closed to a spring-loaded plunger (not shown) which makes contact with the head when the shuttle is in the box.

Title: Improvements relating to protective devices for electrical apparatus
IPC: H01H71/14
Filed: 1925-11-11
Abstract: 265,310. Siemens Bros. & Co., Ltd., Petithory, E. A., and Garrod, E. R. Nov. 11, 1925. Thermal switches for protecting electrical apparatus against continued light overload as well as against short heavy overload, comprise two expanding bellows a, b heated by the same heating coil f and carrying rods a<1>, b<1> which act on opposite ends of a bar o, the upward movement of which operates a protective switch A. A greater mass of metal intervenes between the heating coil f and the bellows a than between the coil and the bellows b so that the bellows b responds more quickly to temperature changes. Adjustable springs m, n act on the bellows, the spring n exerting a greater pressure, and the bellows b may, e.g. be filled with alcohol which has a smaller coefficient of expansion than ether with which the bellows a may be filled, the result being that for short heavy overloads, the rod b<1> rises more than the rod a' while the opposite is the case for long light overloads. The protective switch A is of the kind described in Specification 253,253, and is mounted on a carriage u which can be slid horizontally by a screw s<1> along a rod r and the vertically-moving operating rod 3 of the switch rests on the movable rod o.

A gate contact member 23 is urged into contact with a peripheral zone of one surface 2 of a semi-conductor wafer 1 by resilient means, e.g. a belleville washer assembly 21, acting against an insulating body 15 situated electrically between the gate contact member 23 and a main current contact member 12 contacting a central zone of the surface 2. Both contact members 12, 23 are, in the embodiment shown, provided with leads 11, 27 respectively, which pass through a central bore 17 in the insulating body 15 and are connected to terminals 8, 9 outside the housing 4. A flange 18 of the insulating body 15 is engaged by a further belleville washer assembly 13 to urge the first contact member 12 on to the central zone of the wafer 1. As shown the second contact member 23 comprises a central flat portion 22 and a dependent peripheral wall portion 24 which actually engages the gate zone of the wafer 1. In a second embodiment, however, the second contact member (23), Fig. 3 (not shown), comprises a central flat portion (22) from which extend two outwardly directed arms (53) having downwardly directed end portions (55) which engage the gate zone of the wafer (1). In this case the arms (53) are themselves resilient, and the central portion (22) is urged downwards by a spring (47) operating through an insulating bush (49) in a bore (46) in a relatively massive first contact member (12). The arms (53) extend out through slots in the member (12) and are covered by insulating sleeves (54). The bush (49), the central portion (22) of the second contact member (23) and the bore in the first member (12) accommodate a central gate head (27) bearing a head (51) at its lower end, which head is engaged by the central portion (22) of the member (23) and is insulated from the central zone of the wafer (1) by an insulating spacer (52).

[Class 56.] Delivering molten metal.-The molten glass in the channel of the forehearth of a glass melting furnace is maintained at substantially uniform fluidity by providing a central longitudinal opening in its roof to permit radiation of heat from the centre of the channel and long narrow flames directed downwardly on to the glass adjacent the side walls of the channel. In the construction shown in Figs. 1 and 2 the upper forehearth structure above the channel 1 includes transverse refractory walls 16, 52 and a middle refractory partition 15 dividing the structure in a rear chamber 24 and a front chamber 49. The chamber 24 is bridged by pairs of hinged refractory shutters carried by holders 32 supported by fulcrum rods 35. Each pair of shutters 25 may be rocked independently of the other pairs to vary the heat radiation by chains 38, 39 attached to wheels 40 rotated by handles 42. When closed a space 36 between the ends of the shutters permits the escape of hot gases. Firing chamber 26 extending along the side walls 18 of the chamber 24 are fitted with burners 47, the flames from which pass through slots 21a in supporting blocks 21 and are deflected by lips 18a on the walls 18 on to the side portions of the glass in the channel. The front chamber 49 is provided with two side combustion chambers 51 each having its rear wall composed of refractory blocks, to which is secured a plate 66 carrying a gaseous or liquid fuel burner provided with two series of annular air ports. The delivery end of the forehearth comprises a feed bowl 7 insulated by granular material 9 and fitted with a reciprocating member surrounded by an adjustable rotating tube 13. The front of the forehearth is provided with stacks 81, 82 fitted with adjustable dampers 83, 89. The temperature of the glass may be indicated and controlled by thermo couples 90. Fig. 6 shows another construction of forehearth in which hinged shutters 102 .. 105 pivoted on spindles 106 over openings above the longitudinal channel 100 are opened in turn by the engagement of blocks 119 .. 122 on a slidable rack bar 112 with rocker arms 108 .. 111 on the spindles 106. The rack-bar 112 is operated through reduction gearing by a reversible electric motor 118 controlled by a thermo-couple 130.
