Title: Improvements in or relating to Bundling Machines
Inventor: JOHNSON FREDERICK PAUL
IPC: B65B35/24
Filed: 1967-03-16
Abstract: 1,180,569. Bundling machine; endless conveyers. HENRY SIMON Ltd. 7 March, 1968 [16 March, 1967], No.12282/67. Headings B8A and B8C. A machine for binding a bundle of articles comprises upper and lower conveyers to convey the bundle through the machine, binding means for encircling the bundle with twine and securing it, sensors to detect the trailing extremity of the bundle and stop the conveyers when the bundle is at the bundling station, and means to restart the conveyers when the bundle has been bound. In one embodiment, a bundle, e.g. a stack of carton blanks 94, is compressedly conveyed between endless conveyers 10, 12, each comprising belts 34, 26 respectively running over rollers 36. Its leading face abuts twine held between a needle 80 and a clipping assembly 16. The bundle's movement causes the twine to be folded around its upper; lower and leading faces and the movement is ceased when a trailing extremity 96 has passed the needle 80. The bundle is thus positioned by its initial contacting of switch means to actuate a photocell 110 and by restoration of the beam as it is cleared by its trailing edge. The photo-cell signal stops the conveyer motors 30, 38 after a predetermined delay, this arrangement allowing non-uniform bundles to be bound. During the binding the conveyer 10 is lowered to compress the bundle. The needle 80 then descends, completing the band of twine, the band being secured by a clipping assembly. Details of the thread feed, needle and clipping devices are disclosed in Specification 947,093. The twine is severed below the clip and the bound bundle is conveyed from the machine, the rising needle operating switch means 120 to restart the conveyer. The upper conveyer 10 is supported on arms 46 raisable on guides 42 to take bundles of differing sizes and to exert a predetermined pressure on the bundles, by piston and cylinder means 56 and hand wheels 58. It also has an angled entry conveyer 68 hinged to it and operating at a slightly greater speed than the other conveyers so as not to retard the upper articles in the bundles. The operation of the machine is controlled by limiting switches throughout and the machine has a safety switch 130 operated by excessive upward hinging of the conveyer 68 to react to an oversize bundle to stop the machine. The machine can be moved on wheels 22 engaging rails 24. In a further embodiment, Fig. 4 (not shown), the machine frame is supported on vertically adjustable castors (200). The upper conveyer is slidable vertically on a single tubular support (207) by piston and cylinder means (210), Fig. 5 (not shown), with the addition of spring- loaded manual adjustment, and means is provided to slow down the conveyer as the bundle approaches the tying station. Otherwise the machine is substantially as in the first embodiment. Blowers are provided in both embodiments to clear away thread after severing.

Title: Improvements in selective control mechanisms for change speed gears
IPC: G05G9/08
Filed: 1943-08-06
Abstract: 583,034. Variable-speed gearing. DERUNGS, E. A. Aug. 6, 1943, No. 12745. Convention date, Sept. 24, 1942. [Class 80 (ii)] In control mechanism for change speed gearing, of the kind described in Specification 573,734, the gear change lever 1 is connected to the selector mechanism by linkwork including a disengageable coupling 21, and the selector is connected to the change speed gears by links 8, 9, 10, including a spring coupling 11. The coupling 21 is such that for a part of the stroke of the lever 1 the operated machine is started or stopped, and during another part of the stroke a change of gear ratio is effected. A gear change is effected by a complete up-and-down oscillation of a lever 24 about an axis 25. The lever 24 is connected to the gear lever 1 by links 22, 23, 34, 35, Fig. 6. Links 22, 35, are pivoted about a fixed point 36, and link 34 is rigid with a disc sector 32 pivoted on one part 28 of the coupling 21. The other part 30 of the coupling is slidable in the part 28 and has an arcuate cut-out portion 31. In the position shown in Fig. 6, the machine is in operation. Movement of the lever 1 from I to II stops the machine but does not affect the gear change mechanism as the coupling part 30 slides into the part 28. During movement of the lever 1 from II to IV both parts of the coupling 21 move together and a complete oscillation of the lever 24 is made to change the gear ratio. At position IV the sector 32 again uncouples the parts 28, 30, so that during movement of the lever 1 from IV to V the part 30 slides within the part 28 and the machine is again started up. The same sequence of operations is repeated during reverse movement of the lever 1 from V to I. Each coupling 11, Fig. 3, comprises a sleeve 12 fixed to one part of a link such as 8 and a beaded rod 15 fixed to the other part of the link, a compressed spring 18 abutting flanges on sleeves 14, 17, carried by the rod 15. Thus the spring 18 is compressed whether a pull or a push is exerted on the link.

Abstract: 660,359. Seaming non-metallic sheet material. COMMUNICATIONS PATENTS, Ltd., and BAZIN, R. E. June 10, 1949 [May 10, 1948], No. 12798/48. Class 42 (i). [Also in Group XI] A high-frequency electric field heat scanning apparatus, for seamwelding thermoplastic sheet material or seaming non-thermoplastic sheet material by means of a thermo-sensitive adhesive, comprises relatively movable press members, whereby the work to be dealt with is subjected to heat and pressure between co-operating parts of an electrode system adapted to form a seam of the desired shape, and a movable carrier arranged and adapted to travel to and fro between the press members for transporting the work to and away from a position between the members. As shown, layers of thermoplastic material 9 to be seamed are laid on a sheet metal carrier 8 fixed to a carriage 6 adapted to travel on runways 5. The sheet 8 passes between upper and lower press members 2, 3 which are connected to a high-frequency electric generator 11. An electrode part 10, adapted to provide a rectangular seam, is placed on the layers of material 9 and the carriage is moved to bring the work 9 and electrode part 10 between the press members. The upper press member 3 is then lowered, e.g. by means of a solenoid, to press the work between sheet 8 and member 10 which make electrical contact with members 2, 3 respectively, and the electrode system thus formed is energized to provide the desired seaming. Member 3 is then raised and carriage 6 returned to its original position to withdraw the work 9. The carrier may carry two spaced loads of work so that while one load is being seamed a new load can be substituted for the previouslytreated load. Carrier 8 may be formed with clips &c. for locating the work. A flexible sheet of insulating material, e.g. woven glass fabric, may be substituted for the metal carrier sheet 8, or such an insulating sheet may be used together with carrier 8, being provided with apertures through which the work is loaded on to the carrier.

It is stated that when this alkali metal ferrite is treated with water it is hydrolized with the liberation of an iron oxide, more or less hydrated, which has not been subjected to a high temperature and can be reduced at a much lower temperature than can an oxide which has been heated to a high temperature.ALSO:Magnetizable ferrous powder of particle size not greater than 5000 Angstrom units is made by heating a mixture of iron oxide, or hydrated iron oxide, or other iron compound which yields an oxide on heating, with an alkaline earth metal compound and an alkali metal oxide, hydroxide, or carbonate, the atomic ratio of iron to alkaline earth metal being not less than 9 : 1 and the heating being carried out at a temperature at which alkali metal ferrite is formed, treating the product with water, remvoing the aqueous solution formed, and heating the residue at a temperature below 500 DEG  C. in a reducing atmosphere to reduce the iron to the metallic state.  The alkaline earth metal compound may be the oxide, hydroxide, formate, oxalate or carbonate of calcium, barium, or strontium and the alkali metal compound may be the hydroxide or carbonate of sodium or potassium.  The heating may be carried out at 500-800 DEG  C. to maintain the product in a liquid or semi-liquid state when using an alkali metal hydroxide or at 700-800 to produce a sintered mass when using an alkali metal carbonate and may be in an atmosphere of oxygen-free nitrogen. The final heating at 250-500 DEG  C. may be in an atmosphere of hydrogen flowing at the rate of at least 300 litres per hour for every 10-15 grams of solid.  Ferro-magnetic oxid materials other than iron which are decomposed or reduced to the metal may be added to the mixture.

Title: Improvements in or relating to multi-color kinematograph and other films
IPC: G03C7/22
Filed: 1923-05-18
Abstract: 224,569. Thornton, J. E. May 18, 1923. Kinematograph picture-films; colour photography.-Relates to films in natural colours, of the kind in which the partial images are separately produced on two component films of halfstandard thickness, each comprising a colloid layer on a celluloid or like base, which films are cemented together in register, image-face to image-face, so that the images are enclosed between the celluloid &c. supports, and consists in (1) a four-colour film in which each component film carries two partial colour images, and the image on one film is laterally inverted, and (2) a similar three-colour film in which one of the partial colour images is duplicated on both supports. The images may be produced photographically by any process of full-tone or line, dot, &c. character, or by dye-impression. The thin component films may be printed on film material of the kind described in Specifications 26786/11, [Class 97 (i), Optical systems &c.] ; 213,647, 213,866 and 214,934. The colours for a four-colour film may be crimson and yellow in one component film and blue and green in the other; and for a three-colour film, red, yellow, and blue, one of which is duplicated. Alternatively, the fourth image in the case of a threecolour film may be grey. The partial negatives for printing the film are produced by any known optical apparatus for dividing the primary image from one lens into four secondary images. Such negatives are printed successively in pairs in two layers, one pair on each support. Or the negatives may be made on screen-film which records the images as two two-colour images, and these may be printed by successive printings in two layers on each support, or may be printed to form broken-tone images, the two colours of which are located in adjacent areas on each support. The negative and the positive strips carry marginal identification marks to facilitate assembly for cementing. Registration is secured during printing &c. by means of accurate perforations in the negative and positive films co-operating with accurately fitting pins on the printing &c. apparatus; and to secure uniform shrinkage, the two component films are carried simultaneously through all the various stages of treatment. The component films may be cemented together as described in Specification 232,302. The invention may be applied to non-kinematograph pictures.
