IPC: B65B9/207
Filed: 1963-06-06
Abstract: 1,043,408. Wrapping-machines. ASPRONICHOLAS Ltd. June 5, 1964 [June 6, 1963], No. 22524/63. Heading B8C. [Also in Division B5] In a sachet-forming machine a tube is formed from one or two webs by margin crimp rolls and the transverse seals are made by a pair of reciprocating crimp rolls which rotate at the same peripheral speed as the margin crimp rolls. The machine comprises shafts 34, 35, Fig. 6 (not shown), for rolls of heat sealable web 1 which are fed through the margin and transverse crimp rolls 2, 3 and 7, 8 respectively. Rolls 7, 8 are rotated at the same linear speed as rolls 2, 3. This movement by means comprising a gear train 11, 12 from a common shaft drive 9 and pinion 10, also rotates the rolls 7, 8 through gear trains. Reciprocating movements of the rolls 7, 8 are achieved by mounting them on pairs of arms carried on shafts 24, 25 oscillated by a bell-crank extension 28, follower 29 and cam 30 whose profile is adjustable to govern the time during which the rolls are in engagement with the web. Variable speed motors may be fitted for the separate drives of the shaft 9 and the cam, and the socket length can thus be varied. Reciprocating knife blades 38, 39 separate the contiguous sachets which slide down shoot 40 to delivery conveyer 41. Several parallel lanes of packages may be formed from the one or two webs and separated longitudinally by slitting rolls 43, 44. Control of the web feed to synchronize printed matter with the transverse sealing is possible either by manual variation of the speed of the shaft 9 or through a photo-electric cell 42.

Title: Furnace for continuously heating wire
IPC: C21D9/56
Filed: 1957-07-19
Abstract: 811,613. Wire-heating furnaces. ROSAZ, F. M. July 19, 1957 [July 20, 1956], No. 22985/57. Class 51 (2). A furnace for continuously heating wire prior to a forging operation comprises a refractory lined casing 1, a drum 13 having a shaft 14 journalled in a fixed bearing 15 and a suspended bearing 16, and burners 4-7 with fuel pipes 8 and 9 and air pipes 10 and 11. Compressed air is supplied by a blower 12 which also provides the bearing 15 with cooling air through a pipe 41. The drum, which has a taper of about 1.5 per cent, is driven by a motor 23 through speed control means 24, pulleys 25, 26 and belts 27, reduction gearing 28 and gears 29, 30. The speed control means 24 is of the infinitely variable type operated by a reversible motor 32 through chain and sprocket gearing acting on the gear 31. Wire is introduced through a cat-trap 18 near the bottom of the wider end of the drum, and is withdrawn through a cat-trap 20. A spring-pressed bar 45 bears against the drum at the inlet end to guide the incoming wire away from the end of said drum. Initially, the wire is drawn into the heated furnace through the inlet and its bent end is hooked into a hole 57 registering with the outlet, and the drum is rotated slowly until a sufficient number of turns is wound on to it. It is then stopped with the hole 57 near the outlet, the free end of the wire being drawn therethrough. During operation the turns of wire on the drum expand and tend to move by gravity away from one another towards the smaller end of the drum.

Abstract: 531,952. Valves. AIR CONTROL INSTALLATIONS, Ltd. Aug. 9, 1939, No. 22994. [Class 135] A byepass or changeover valve is provided with one or more inlet openings and two or more outlet openings and with a number of flexible valve plates adapted to be moved rapidly from one seat to another. In the form shown in Fig. 1, the device has one inlet opening 2 and two outlets 3, 4, controlled by a pair of plates 5, 6 carried by a sleeve 12 slidably mounted on a rod 13 supported by a bracket. The discs 5, 6 are corrugated to increase their strength and elasticity and have rings, 8, 9 of rubber or other resilient material around their peripheries. The valve is actuated by a pair of toggle-links 16, 17 moved by a shaft 15 provided with a handle 14. The handle works between stops 18, which may be adjustable, so arranged that the handle is arrested when the links are just past their dead centre positions so that the elasticity of the plates holds the valve in its adjusted position. The valve may be actuated by a quick-threaded screw, a cam or a rack and pinion and a locking catch may be provided to secure the valve in its adjusted position.

Title: Improvements in machines for grinding and polishing lenses
IPC: B24B13/02
Filed: 1924-09-29
Abstract: 244,849. Long, E. M. Sept. 29, 1924. Lenses, grinding and polishing.-A lens is ground or polished by a rotating lap across the surface of which the lens is oscillated in a curved path. On a table 1 is supported a two-part housing 2, a waste receptacle 3, and a post 7 for the lens holder 6. Within the housing is mounted a shaft 22, and secured to the upper end of the shaft 22 is a conical nut 30, which receives a lap 5, and also secures in place a cap 16 covering a flange 17 of the receptacle 3 to deflect dust &c. into the receptacle. The shaft runs in a bearing 23 and in a hub 10', and has loosely mounted thereon a clutch member 31 driven, through gearing 32, 33, by a shaft 19 and having an inner face 34, which is engaged, when the clutch is in gear, by lugs 39 on levers 37<1>. The levers are pivoted at 38 to a clutch section 36 secured to the shaft 22 and are rocked to bring the clutch into and out of gear by a collar 41 slidable on the shaft. The collar is pressed down by springs 55 and is moved by a lever 42 operated, through a shaft 45 and an arm 47 thereon, by a lever 49. The lens holder 6 is engaged and moved by a member 94 held in either of two sockets 100, 101 in a spring-pressed shaft 96 mounted in a section 84 of a bracket 9 and oscillated about its axis by a rack bar 81 engaging a pinion on the shaft. The rack bar is reciprocated by a rod 79 having thereon a collar 78 engaging an eccentrically bored hub 73 of a hand-piece 72 slidably mounted on a spindle 71, which is secured eccentrically to a shaft 65 journaled in the post 7. In order to vary the stroke of the bar 81 a disc 70 is mounted on the shaft 65, and in the disc are a number of recesses 75, any of which may be engaged by a pin 74 on the hub 73, the hub being raised on the spindle 71 and rotated, a spring 77 serving to press the piece 72 down to retain the pin in a recess. The bracket 9 comprises three parts, namely, two members 87, 88 adjustable around the axis of the post 7 and clamped by bolts 90, a part 83 adjustable about a horizontal axis in the member 87, and clamped by one of the bolts 90, and the section 84 which is adjustable vertically on the part 83 by a pinion 103 and a rack 102; by adjustment of the bracket parts, the position and pressure of the lens on the lap may be adjusted.

A light anti-tank gun comprises a barrel which recoils on a support, firing means both for propelling a projectile and for a counterrecoil charge and means for igniting the counterrecoil charge at the moment the projectile leaves the barrel. The round of ammunition comprises a projectile 1 engaged in a case 2 having a priming device 3 for the propellant charge 17 and a priming charge 5 connected to a delayed pyrotechnic firing device 6 for the counter-recoil charge 4. The charge 5 is also connected to an electric firing device 7. The round is held in the barrel 11, which is supported on guiding rings 14, 15, by abutment of the bottom peripheral plate 23 of the round with a shoulder 22 on the breech 20 having a nozzle 21 connected thereto. The breech is releasably attached to the barrel by locks 24 which engage behind the peripheral ring 25 of the barrel and are normally urged upwardly by spring-loaded levers 28. When the trigger 16 is pulled the projectile is caused to move down the barrel 11 which recoils freely, cams 34 thereon rocking stops 31 about their pivots 29 as they move thereby. When contacts 10,12 on the barrel 11 and support 13 abut the electric circuit of the fuse 7 is closed and the counter-recoil charge 4 is ignited at the moment the projectile leaves the barrel. The pyrotechnic charge 6 is calculated to also fire the charge 4 when the projectile leaves the barrel and acts as a safety charge. The firing of the charge causes the barrel to reverse its direction of movement and when cams 34 on the barrel move past stops 31 they rock the stops about pivots 29 which act on the levers 28 to raise the ends thereof above the height of studs 35 on the locks 24, so that the latter are moved out of engagement with the end of the barrel as the latter moves forwardly to permit the breech 20 to tip over on the guides 27, one of which is shorter than the other to permit such tipping.
