Title: Improvements in machines for applying cork tipping or other material to a continuouscigarette wrapper or other strip
IPC: A24C5/58
Filed: 1930-05-20
Abstract: 357,203. Affixing sheet material by adhesives. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) May 20, 1930, No. 15507. [Class 73.] In machines for applying sections of covering material to a continuously fed strip of wrapping material, a knife cuts transversely across the strip and is movable in an orbital path in a plane which crosses the strip in an inclined position to the strip, causing the knife to move with the strip while cutting the same, and a ledger plate moves forwardly with the knife and the strip. In a cork tipping machine for making cigarettes, a cork strip C is fed through adjustably-mounted guide plates 48 to rollers 27, 28, guide brackets 50, and a ledger plate 47. The ledger plate is carried by an arm 46 attached to a slide 44 carrying rollers 40, 41 reciprocated by a cam disc 39 on a knife shaft 17, which is inclined to the horizontal plane. To clamp and release the knife, a knife disc 32 supports fingers 35 shaped like bell-crank levers, which clamp a knifeblade 36 to the disc 32 with one arm and with the other arm engage a recess of the clamp bushing 37. The paper strip P is guided through an adjustable plate 95 to rollers 77, 79 the former having projections 78 spaced at lengths of two cigarettes apart. It receives paste from a paste drum 65 rotating in a bowl 64 adjustably mounted on the frame 55. An adjustable scraping plate 71 controls the amount of paste carried by the paste drum 65. The paper then passes between rollers 80, 81 which can be moved relative to each other by a screw 89, and are so placed that the distance of their centre line from the knife 36 corresponds with the length of one cork tip. Each tip is pressed upon a pasted part of the strip P, which is then carried round a drum 82 where the tips are firmly pressed on to the paper strip as they pass on the inside. To alter the position of the rollers 80, 81 relative to the cork strip feed, these rollers are carried by a double lever arm 91 provided with an adjusting screw 93. In a modification, the paste is applied to the cork strip by passing it over a paste drum.

Abstract: 971,601. Recording television signals. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. April 24,1962 [April 26, 1961], No. 15558/62. Heading G5R. Video-frequency signals are satisfactorily recorded on and played back from audio-frequency grade tapes by recording the same carrier,frequency modulated by the video signals on to two tracks of the same or associated tapes, mixing the outputs on playback in proportion to their respective playback amplitudes and limiting the mixture to a predetermined level. At the transducing speeds involved, each track may be affected by drop-outs &c. up to 3% in the system, but the combined output will only be subject to the product of these effects, namely 0.1%. Where one tape is used, the two recordings are preferably separated physically by half of one picture element, so that the same tape fault affects only one track but the tracks are not differentially phase-affected by tape stretch or shrinkage.

Abstract: 129,355. Railing, A. H., and Angold, A. E. Oct. 30, 1917. Arc lamps.-In a magazine lamp, approximately alined carbons are fed by two bellcrank levers D<1>, D<2>, Fig. 1, pivoted to the magazines and connected together by a pin R' and slot R<2>, the pin R' moving in a line with a pivot C for one of the magazines, which can thus swing freely to strike and regulate the arc. The bell-cranks may be operated by a crank F engaging a slot in one of them. A ratchet-wheel S, Fig. 4, geared to the crank-shaft is rotated by a pawl U on the armature of a shunt electro-magnet T provided with a make-and-break device. A guard-plate A<2>, normally preventing the pawl from rotating the ratchet-wheel more than one tooth at a time, is moved out of action by a pin A<4> on the swinging magazine if the arc breaks, and also by a cam A<6> on the crank-shaft when the bell-cranks are returning rapidly to pick up fresh carbons. This return motion may be effected by inclined springs M<1>, M<2>, Fig. 1, which also press the arms towards the magazines. Each bell-crank carries a catch H, Fig. 3, engaging the butt end of a carbon and bearing against the bellcrank D<2> and the side of the magazine at fulcra K, K<1>, so situated that most of the pressure of the spring is borne by the magazines, and the catch is easily deflected in passing to the back of a fresh carbon. The carbons are frictionally gripped at the nozzles B<2> of the magazines.

Abstract: 457,616. Front glasses for light projectors. GRAVES, A., Sunny Cottage, Wheathampstead, Hertfordshire, and CODD, R. G., 9, Temple Fortune Court, Golders Green, London. June 1, 1935, No. 16001. Convention date, June 4, 1934. [Class 75 (ii)] In a light projector, suitable for use as a road vehicle headlamp or as a landing lamp for aircraft, of the kind comprising two or more selectively operable sources of light, one situated at the focus of a parabolic or like reflector and another in a non-focal position and associated with a screen so as to produce a flat-topped divergent beam passing through substantially one half of the front glass, as described in Specification 210,105, [Class 39 (ii)], this half of the front glass is provided with shallow vertical or substantially vertical oneway prisms or half flutes symmetrically disposed in two groups one on each side of the vertical centre line of the front glass, the angle or curvature of each prism or half flute being large enough to cause a narrowing of the beam obtained from the non-focal source of light but not so large as to cause a separation of the beam obtained from the focal source of light into non-overlapping beams. The front glass is formed with diverging prisms or half flutes on its upper half, or converging prisms or half flutes on its lower half, according to whether the non-focal source of light is, respectively, in front of, or behind, the focal point of the reflector. The prisms or half flutes may be formed integrally on the inner or outer face of the front glass, and the curvature of the half flutes may be convex or concave. Additional light-refracting devices may be imposed on the prisms or half flutes or on the other half of the front glass. In the form shown in Fig. 1, the upper half of the front glass 11 is formed with vertical prisms 12. Fig. 6 shows the centre prisms 17 cut short and replaced by upwardly reflecting horizontal prisms 18. The positions of the prisms 17 and 18 may be interchanged. Fig. 9 shows prisms 23 inclined inwardly towards the vertical centre line of the front glass. The Specification as open to inspection under Sect. 91 states also that the invention is applicable to lamps of the kind described in Specification 188,057, [Class 75 (iv)]. This subject-matter does not appear in the Specification as accepted.

Abstract: 1342929 Aligning pins of electrical components; twisting axially HUGHES AIRCRAFT CO 20 May 1971 [28 May 1970] 16019/71 Headings B3A and B3E Non-circular pins 17 projecting from an electrical component are accurately aligned to facilitate subsequent interconnection by a wire wrapping machine, by twisting them beyond their elastic limit. An alignment head 14, Fig. 2, for operating on four pins 17 at a time, is connected to each end of a boom (18) (Fig. 1, not shown) the movement of which is automatically controlled. Each head 14 includes four pin sockets 15 each having a flared end and an axial bore of square section. The sockets 15 are lowered over the free ends of square section pins 17 by moving a rod 28 by a pneumatic actuator 29 to cause springs 27 and 22 to be compressed and a housing 20 carrying the sockets 15 to be lowered. Upon further downward movement of the rod 28, a cam follower 35 moves within a curved portion 34a of a cam 34 to cause the cam 34 to rotate a pinion shaft 33, which in turn rotates the sockets 15 through 180 degrees so as to twist the pins about their axes. During the return stroke of the rod 28, the configuration of the cam track 34a is such that the sockets 15 are rotated a certain amount in the reverse direction to facilitate subsequent retraction, are lifted free of the pins 17 and then rotated back to their initial positions. If a pin 17 is laterally misaligned, it is deflected by the tapered end of the socket 15 into the internal bore of the socket 15. If a pin 17 is circumferentially misaligned, the socket 15 engages the pin 17 during its downward movement and is then forced upwardly against the action of a spring 31. During the subsequent rotation of the socket 15, proper engagement can occur when the bore of the socket 15 becomes aligned with the pin 17.

Filed: 1925-06-22
Abstract: 235,913. Zoller, A. June 21, 1924, [Convention date]. Drawings to Specification. Pumps, rotary.-The mean pressure or torque of an engine charged by a compressor is maintained constant or increases up to a certain engine speed by arranging that the delivery pressure of the compressor rises at the same rate as or at a greater rate than the increase in the resistance to flow of the charge through the intake passages; above the determined speed the amount of charge per revolution of the compressor is gradually reduced. As applied to an engine for use on a road vehicle the change-speed gear may be dispensed with or the number of changes reduced by using a compressor, the suction or delivery or both of which is or are controlled bv a centrifugal governor driven by the engine to control the supply of the charge as stated. Instead of controlling by means of a governor, the effect can be obtained by reducing the cross-section of the suction or delivery ports.

Scoop-arm machines. - In loading shovels which are moved forward at first and then upward while at the same time they are rotated to one side and tilted by means of a toothed segment gear, a common rocking axis is arranged for the engine, shovel and segment. The shovel 85 is operated by a compressed-air cylinder 30 carried by trunnions 20 in bearings 61 of a support 10 carried on a pin 9 of a bracket 8 which is rotatable about a vertical axis in a bearing 2 in the frame 5. Cooperating with a rack 7 in the frame 5 is a toothed segment 14, of elliptical shape, on the trunnion 20, and opposite the rack is an inclined track 7<a> on which is supported one of the uprights of support 10 by means of a roller 11. The shovel 85 is secured to the piston rod 39 and is also carried by a rod 32 on which are mounted rollers 35 adapted, when the shovel is pushed forward, to ascend cams 41 and rock the shovel. The boss 14<a> of segment 14 is loosely mounted on its trunnion 20 and is recessed at 56 to receive a dog 57 on the trunnion 20, the recess being wider than the dog to allow play between them. To prevent play on the return movement, a spring 59 urges a wedge 58 on the segment 14 into the space formed in the recess 56 when the dog 57 moves forward, the wedge being withdrawn by a projection 73 thereon engaging a lug 72 on the frame. When the shovel is moving outwards along the shaking shoot 4 it rocks the cylinder 30 and when the rollers 35 ascend the cams 41, it is raised. The dog 57 then engages the face 56<a> of recess 56 and causes the segment 14 to roll on the rack 7 so that the shovel is rocked to one side and tilted. On its return movement, the shovel is forced into its initial position by the weight of the material advancing in the shoot, aided, if necessary, by admission of air to the front of the piston.
