Title: Improvements relating to numbering machines
IPC: B41K3/12
Filed: 1931-06-22
Abstract: 388,386. Printing- machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Du Pont-Pathe Film Manufacturing Corporation ; 35, West 45th Street, New York, U.S.A.) June 22, 1931, No. 18079. [Classes 100 (i) and 100 (ii).] Number - printing apparatus ; inking - apparatus; feeding webs ; cleaning printing-surfaces. -I n a numbering- machine for continuous lengths of kinematograph film &c., the numbering-discs are mounted on a rotary carrier on an axis at right-angles to the carrier axis and form an arcuate printing-surface ; the carrier is rotated to give a surface velocity equal to the velocity of the film. A drum 1 is driven from a film perforating or like machine by a sprocket chain 11, and a carrier drum 2, pressed against the drum 1 by adjustable spring pressure, is driven from the drum by gears 13, 14. The film passes over a roller 8, between the drums 1, 2, and over a roller 9, and thence round a floating roller to a friction-driven rewind spindle. The numbering-discs 53 are mounted on an axle 49 in the carrier 2 and drive each other by pawl-and-ratchet mechanism as usual. The units disc is driven by a pawl 55 on a lever 40 which is connected to a yoke 42 sliding on the carrier 2. The printing-mechanism may also include hand-set discs, which may be locked in position. The yoke 42 is oscillated by a roller 44 running on the edge of a cam 7. The inking-device comprises a milled roller 63 rotating in a trough 59, which is fitted with a wiping-pad 64. A small felt roller 71 lies in contact with the roller 63 and can be adjusted to contact the type by means of arms 74. The types are wiped by a brush 5 and the change of number takes place between the wiping and inking points. Auxiliary guide rollers 82 and 82a, mounted on spring-pressed arms 78, press the film to the drum 1, which is provided with projections 84 to engage the holes in the film. The guide rollers may be provided with slightly-raised tracks 85 to support the film.

IPC: F26B9/06
Filed: 1917-12-06
Abstract: 119,156. Clarke, L. B. Dec. 6, 1917. Trays.-Drying-trays are formed with metal baffle or deflector plates secured to their under side, so that, when arranged vertically in a stack, they form a self-contained unit. The end rails are narrower than the side rails and disposed so as to leave a space below a perforated &c. false bottom at one end and a space at the upper part of the tray at the other. Figs. 5 and 6 show the ends of a tray. In Fig. 6 the end bar is shown raised, leaving an opening 8 to admit air to the space between the perforated bottom 5 and the imperforate plate 6. Fig. 5 shows the opposite end with an opening 9 above the bar 2. The stack of trays may be bodily introduced and re. moved from the drying-chamber by means of a trolly. In a modification, openings are left above and below at both ends, but may be entirely or partially closed by sliding plates mounted on the end bars Figs. 1 and 13 show trays constructed according to the invention arranged in drying- chambers with air-inlets 14, 15 and outlets 16.

Title: Improvements in or relating to aircraft arrester gear
IPC: B64F1/02
Filed: 1945-07-20
Abstract: 642,705. Winding and paying-out apparatus. BODDINGTON, L., and FAWELL, H. D. July 20, 1945, No. 18698. [Class 78 (v)] [Also in Group XXXIII] Arrester cables 1-8 on an aircraft landing- deck are coupled in pairs to blocks 10-13 slidable in guides 14 below deck and connected by a common cable 17 to a winding-drum and friction brake 18. The pairs of cables 1, 5; 2, 6; 3, 7 and 4, 8 are connected to the blocks by cables 1a, 5a; 2a, 6a; 3a, 7a and 4a, 8a extending between the port end of one arrester cable of a pair to the starboard end of the other cable, so that engagement of the aircraft with one cable will cause movement of the corresponding block and tensioning of the other cable. The cables are guided by pulleys 9 on the deck and pass through fairleads 9a in the deck and around pulleys 1b-8b on the blocks. The cable 17 passes alternately around pulleys 16 on the blocks and fixed pulleys 15, so that a pull on one of the blocks causes the required amount of cable to be unwound from the drum and at the same time maintains the other blocks in their initial positions with the inoperative cables under tension.

Abstract: 747,459. Aircraft undercarriages. BLACKBURN & GENERAL AIRCRAFT, Ltd., and THIRSK, W. H. June 25, 1954, No. 18712/54. Class 4. A retractable undercarriage for aircraft comprises a rigid leg 1 pivoted at its upper end to the aircraft for sideways retraction and pivotally attached at its lower end to a freely swinging arm 2 which supports a landing wheel 3. The arm 2 is pivotally connected to a shock absorber 4 connected at its upper end to an arm 8 pivoted to the leg 1 and fast with a bevel pinion 9 meshing with a further pinion 10 connected by a shaft 11 to a gear wheel or sector 12 in turn meshing with a fixed sector 13. The leg is retracted by a jack 7 through a back-stay 5, 6 and during retraction movement of the leg about its pivot the sector 12 is caused to roll round the sector 13 and thereby rotate arm 8 and the movable undercarriage elements from the full line to the chain-dotted position shown in Fig. 1. To relieve the link 8 of taxying loads a stop 14 is provided for engagement by the cylinder of the shock absorber and the leg may carry a fairing panel to close a structural opening when the undercarriage is retracted. Specification 686,953 is referred to.

Abstract: 774,955. Centrifugal strainer separaters. WESTERN STATES MACHINE CO. June 28, 1955 [July 6, 1954], No. 18718/55. Class 46. [Also in Group XXV] A centrifuge adapted to receive material to be treated through a gate-controlled outlet from a source of supply and having a rotary basket with an opening through which the material enters it, is provided with a cover or door for the opening biassed to close it and movable either by hand or fluid pressure, the latter operating through a control means which also acts on a valve associated with the outlet gate to keep them both closed or both open. Sugar massecuite or magma are fed from a tank through a spout 22, Fig. 5, having a gate 20, opened and closed by a power cylinder 26 to which compressed air is fed under control of a device 26a, into a centrifuge basket surrounded by a curb 10 and covered by a curb top 16, Fig. 2, in which is an aperture 18 through which the material passes into the basket. A fixed door-segment 32 and a movable segment 34 co-operate to close the aperture. The movable segment 34 swings aside on curved links 38, 40 in parallel ruler fashion when compressed air is fed to a power cylinder 50, the movement extending a return spring 66. Compressed air is supplied past a main control valve GSV, lines 148, 144, three-way valve 63 and line 62 to the cylinder 50, the line 148 also supplying the upper compartment 164 of a valve chest 160 in which a spring pressed valve isolates the upper compartment 164 from a lower one 166 in communication with the control means 26a for the gate 20. When the power cylinder has opened the door 34, a latch 182 on the link 40 engages an arm 180 to open the valve 176 and admit pressure air to the chamber 166 from which it flows to the control 26a and power cylinder actuating the gate 20. The rate of movement of the door 34 is controlled by valve units 122, 124 each comprising a needle valve bye-passed by a non-return valve arranged in the line 62. When the door is closed, drips from the gate 20 are caught in a trough 98 formed in the door and drop therefrom into a tray 108 whence they fall on to the sloping top of the basket.
