Title: Improvements in or relating to Printing Devices.
IPC: B41L15/06
Filed: 1916-04-17
Abstract: 104,074. Goss Printing Press Co., (Goss Printing Press Co.). April 17, 1916. Printing-surfcaces; fudge boxes.-Relates to fudge boxes and means for securing them on their supports. The base-plate 27 of the fudge box is provided at one end with a bevelled part 28 to engage a rib 22 on a sleeve 21 secured to the supporting-cylinder 20, and at the other end with two bevelled lugs 29, 30 adapted to be engaged by lugs 34 on a clamp 31 mounted in a recess in the sleeve 21. The clamp is provided with a fulcrum projection 35 and is slotted so that it can be moved circumferentially of the cylinder 20 on the clamping-screw 32 so as to clear the lugs 29, 30 to allow ready removal or replacement of the fudge box. A number of fudge boxes may be secured to the sleeve 21 and are positioned by keys 25 on the sleeve engaging slots in the base-plates 27. The spacing-leads 36 are mounted in slots in a spacing-ring 38 integral with the base-plate 27 and a loose slotted ring 37 placed in a recess in a fixed head 40. The type-bars are clamped between knife-edges on the head 40 and on a movable head 46 overhanging the ring 38. The head 46 is operated by a slide block 47, to which the head is connected by screws 48, Fig. 8, allowing a little relative movement, and springs 50 urge the head away from the slide block. A circular block 51 rotatable in the block 47 is provided with an eccentric pin 54 engaging a block 55 slidable in a recess 56 in the base plate 27. The block 51 is rotated to move the head 46 into the clamping or releasing position by means of a square tool inserted in a hole 57 in the block 51, and is locked in either position by the head of a spring-pressed pin 62 engaging either of two recesses in the block 51. The locking-pin 62 is moved back to release the block 51 by means of pins 59, 60 mounted in the recesses and operated by the tool. A pin 61 is mounted in the block 51 with its head normally engaging one of two recesses 64 in the slide block 47, and the pin is of such a length that, when the block 51 is turned so that the head of the pin moves out of the recess 64, the inner end of the pin moves into a hole in the tool so as to prevent the removal of the tool until the slide block has been moved to either of its extreme positions.

Title: Spark-ignited engine
IPC: F02B23/08
Filed: 1976-02-13
Abstract: 1536971 Turbulence chambers in I C engine cylinders M G MAY 13 Feb 1976 05787/76 Heading F1B A 4-stroke spark-ignited I.C. engine has, in its cylinder head, a swirl chamber 21 in which is mounted an exhaust valve 17, the chamber being provided with an eccentric inlet duct 26 arranged to provide uni-directional vortexial flow of mixture within the chamber (see arrow B) towards the end of the engine compression stroke. A spark-plug 27 is mounted in the chamber 21. To promote anti-clockwise rotation of the charge as it enters through inlet valve 14, the inlet passage 15 may be tangential to the cylinder longitudinal axis, as may be the exhaust passage 19 extending in the opposite direction to inlet passage 15 to improve scavenging. The piston may be flat-crowned or slightly arced and the inlet duct 26 may be formed either in the cylinder head or wholly or partially in the piston crown (not shown). The chamber 21 may also extend partially into the piston crown (not shown). In Fig. 6, the inlet and exhaust passages 15, 19 extend in the same direction, the chamber 21 is oval, and the inlet valve 14 is also formed in a shallow recess 31 in the cylinder head, with the duct 26 extending between the recess 31 and chamber 21 to induce a mixture flow as indicated by arrows C, D and E towards the end of a compression stroke. The igniter 27' is located in the chamber 21 as far downstream with respect to this flow as is possible and a further duct or ducts 70 may be formed to reinforce the vortexial flow (see arrow H). A further inlet valve 34 may debouch into the chamber 21, for the introduction of rich mixture, in which case inlet valve 14 may introduce only air into the engine. In both embodiments the duct 26 may be subdivided into several parallel ducts (not shown).

Abstract: 1463712 Corona charging apparatus ELFOTEC AG 8 Feb 1974 [9 Feb 1973] 05859/74 Heading H1X A charging arrangement comprises a first electrode in the form of a sheet 5, a second electrode emitting corona and comprising a plurality of component electrodes 11 to 16, and fieldconnecting means 21 and 22 to provide a uniform current density over the charging area. The sheet 5, which may be of insulating material metallized on its lower surface is supported by conductive rolls 2 and 3 mounted on a chassis frame 1. Supporting walls 8 and 9 mounted on the frame 1 have holes 10 through which a wire is drawn to produce an arrangement of parallel wires 11 to 16 connected to the central conductor 17 of a cable 18 leading to one terminal of a high-voltage source, the other terminal of which is connected to the chassis frame 1. The field-correcting means 21 and 22 are plates, preferably of corona-resistant insulating material, e.g. P.T.F.E., attached by supports 23 and 24 to the walls 8 and 9. Insulating sleeves 25 intermediate the wire runs 11 to 16 provide further field-correcting means. As an addition to the plates 21 and 22, the peripheral field may be connected by making the two outermost wires 11 and 16 so thick that no corona discharge occurs at these wires.

Title: Film cartridge for use with motion picture cameras
IPC: G03B17/26
Filed: 1963-02-14
Abstract: 1,020,932. Cine cameras; double-run film cartridges. BELL & HOWELL CO. Feb. 14, 1963 [Feb. 23, 1962], No. 5990/63. Heading G2E. A double-run cine film cartridge has an indicator 75 to show whether either or both sides of the film have been exposed. The cartridge 27 may be loaded by the user with a film spool 61 whose end passes under clip 67 as in Fig. 19 (not shown), i.e. no take-up spool. The camera has a footage counter actuated by the insertion of the cartridge, the counter stopping the film drive before the end of the run so that some turns remain on the supply spool which becomes the take-up spool then the cartridge is reversed for the second run. When the cartridge cover 80 is opened, spring 83 pivoted on the base 79 in Fig. 18 (not shown) and indicator plate 76 are biased to the position of Fig. 20 (not shown) and an "O" appears through aperture 89 in the cartridge. As the first side of the cartridge enters camera 11, pin 86 in the camera turns indicator 76 counter-clockwise so that detent 85 on spring 83 seats in one of the grooves 82, and numeral "1" shows in aperture 89 as in Fig. 21 (not shown). The entry of cartridge 27 causes lever 28 to pivot away from pivoted lever 22 whose end 26 is then held against the periphery of footage dial 24 until the film is almost run off spool 61 when end 26 falls into recess 35 whereby stop pawl 18 on the other end of lever 22 contacts and stops cluster gear 12 through its projections 14, hence stopping the camera drive. Cartridge 27 is then removed from the camera and lever 28 is thus allowed to force lever 22 out of engagement with the footage dial 24 and to lift worm gear 30 from driving engagement with toothed periphery of dial 24 whose spring 32 then returns it to its initial position. As the cartridge is re-inserted in the reversed position, pin 86 presses plate 76 at its other end until number "2" shows. The film drive has a shuttle tooth 40 as in Figs. 5 and 9 (not shown) reciprocated in the film plane by eccentric pin 42 integral with shuttle and shutter shaft 43 driven through gear 45 by face gear 46 on cluster gear 12. Tooth 40 is moved into and out of the film plane by lift cam 48. The camera drive may be manually controlled by pivoted member 19 which has a stopping pawl 17 to engage projections 14 on gear 12 and which is actuated by an external starter button.
