Title: Gas lighter
IPC: F23Q2/28
Filed: 1965-12-28
Abstract: 1,119,375. Piezo-electric generators. MANSEI KOGYO K.K. 28 Dec., 1965 [29 Dec., 1964; 2 June, 1965], No. 54924/65. Heading H2A. [Also in Division F4] In a lighter gas issuing from a burner 6 is ignited by a glow discharge across electrodes 5a and 5b generated by a hammer 33 striking a piezo-electric device 1. A resistor 4, Fig. 1 (not shown), connected between one electrode and the piezo-electric device forms in conjunction with the inherent capacitance 2 of the device a time constant circuit which will cause the glow discharge of lower temperature but longer duration than is normal with an internal spark. The hammer is propelled towards the elements by a push button 9 normally held in its inoperative position by a coil spring 41. The hammer is supported in an inner frame 10 by overcentre springs 42 which extend between a peripheral groove 55 in the lower part of the hammer and openings 44 in the frame. When the push button is depressed the head 32a of a rod 32 rigid with the push button moves a distance X within a cavity formed in the hammer before causing the hammer to move towards a metallic cap Ia of the piezo-electric device 1. When the groove 55 passes through line A-A<SP>1</SP> serving as the dead centre for the springs 42 the hammer is caused to accelerate sharply towards the cap Ia. The device 1 is rigidly supported in insulation 38, 39 and the positive poles of the piezo-electric elements are connected to electrode 5a through conductor 37 and lead 8. The negative poles of the device 1 are connected to electrode 5b by a lead not shown. The frame 10 may replace this lead in which case the supports 38, 39 are made conductive. Also the electrode 5a may be replaced by a bored metallic cap 6a, Fig. 4A (not shown), mounted on the outlet end of the burner and insulated therefrom. A gas valve 17 mounted on the liquid gas container 16 is opened by a lever 18, pivoted at 19, contacted by the hammer when it is depressed. In Fig. 5 (not shown), the push button may be replaced by a sliding member 9a, and an opening 46 or holes 47, Fig. 6 (not shown), be formed in the outer lighter casing to allow venting of combustible gases from the interior of the lighter.

Filed: 1972-11-29
Abstract: 1345861 Inserting terminals in panels; shearing AMP Inc 29 Nov 1972 [14 Dec 1971] 55030/72 Headings B3A and B3W Apparatus for severing terminals 2 from a carrier strip 3 and securing the terminals to a panel 14 comprises, a mechanism for intermittently feeding the strip along a feed path to position terminals at a shear block 76, Fig. 8, a terminal gripping member 78 spaced from the shear block which member is resiliently biased towards the shear block, the shear block and gripping member being movable against the bias to sever the leading terminal from the strip and to position the severed terminal in the path of an insertion punch 24, which is movable laterally of the direction of movement of the shear block. At the beginning of the work cycle a severed terminal is held by the shear block 76 and gripping member 78 in alignment with the insertion punch 24. A ram is driven downwardly by a piston cylinder 32 and the terminal to be inserted into a printed circuit board 14 is picked up by the punch. The terminal is held by a spring loaded ball 50 in a recess 48 in the punch and an inclined surface on the punch 24 engages a similar surface on the member 78 to move it against a spring 98, thereby releasing the terminal for downward movement through a recess 86 formed in the shear block and gripping member. At the end of the downward stroke, a rod 122 closes a switch 120 to energize the cylinder 32 to retract the ram and pressurize a cylinder 72 to retract a feed finger 58. When the rod 122 closes a switch 118, a cylinder 82 is pressured to align the shear block 76 and gripping member 78 with the feed path of the terminal strip. A rod 130 on the block 76 closes a switch 128 to pressurize the cylinder 72 to advance the terminal strip. At the conclusion of strip feeding, the cylinder 82 drives the shear block 76 to the right, shearing the leading terminal in co-operation with a shear blade 90 and aligning it with the insertion punch 24.

Filed: 1969-12-03
Abstract: 1280659 Feeding webs SCHWEIZERISCHE INDUSTRIE GES 3 Dec 1969 [3 Dec 1968] 58926/69 Heading B8R [Also in Divisions B4 and F2] In apparatus for cyclically performing work operations, e.g. cutting and welding, or moving elongate material such as paper, tubing or cables, feeding and processing assemblies are provided, each assembly having a pair of parallel shafts associated with inter-related drive members and couplings so arranged that the shafts of one assembly are rotated at a uniform rate whilst the shafts of the other assembly are rotated alternately at a higher and a lower rate during each cycle of operation. As shown, a paper web 2 from a supply roll mounted on a shaft 1 is fed to a cutting device 13 by means of rollers 4 mounted on two vertically spaced shafts 5 and 6 which are coupled together at one pair of adjacent ends by similar intermeshing gear-wheels 7; at their other ends the shafts 5, 6 are coupled together by way of respective electromagnetic couplings 8, 9 and two intermeshing gear-wheels 10, 11, the gear-wheel 10 having more teeth than the gear-wheel 11. The gear-wheel 10 meshes with a driven gear-wheel 12 which also drives the cutting device 13 constituted by coupled shafts 14, 15 carrying cooperating knife blades 17, 18. Thus, when coupling 9 only is energized the shaft 5 is driven by the gear-wheels 12, 10, 11, the closed coupling 9, the shaft 6 and the gear-wheels 7 at a number of revolutions corresponding to a feeding speed V 1  of the web 2; when coupling 8 only is energized the shaft 5 is driven by gear-wheels 12, 10, and the closed coupling 8, and drives the shaft 6 through the gear-wheels 7 at a speed of rotation corresponding to a feeding speed V 2  of the web 2, V 2  being smaller than V 1 . A control circuit (Fig. 2, not shown), including a cam operated switch 22 asosciated with the cutting device 13 and a photo-electric scanning head 24 responsive to marks 23 on the web 2, controls the energization of the couplings 8, 9 so that the web is advanced alternately at a higher rate and a lower rate during each operating cycle of the cutting device. The Specification explains, with reference to Figs. 3 and 4 (not shown) how this arrangement results in the cutting of the web at predetermined points into pieces having a length equal to the distance a between the marks 23. In a modification (Figs. 5 to 7, not shown) the scanning head 24 is omitted the shafts 5 and 6 are driven at a constant speed and the couplings 8, 9 are associated with the cutting device 13 the shafts of which rotate alternately at a higher rate and a lower rate during each operating cycle as the couplings are selectively energized by a circuit including a cam-controlled switch associated with the shaft 5.
