IPC: B08B9/032
Filed: 1958-02-26
Abstract: 835,176. Cleaning heat-exchangers. K. E.- PATENTER A.B. Feb. 26, 1958 [April 12, 1957; Oct. 3, 1957], No. 6287/58. Class 99(2). In apparatus for cleaning boiler tubes 2 and the like by dropping cleaning particles through the flue 1, one or more horizontal or slightly sloping rebound surfaces 6, Fig. 1, are arranged below the tubes 2 so that the cleaning particles 9 rebound therefrom to clean the lower surfaces of the lowermost tubes. The particles are dropped from funnels 5 and the rebound surface 6 may be vibrated to move the particles collecting thereon to an outlet 7. A grating 11 prevents the particles being carried through the outlet 4 for the flue gases. In a modification a perforated rebound surface is arranged immediately below the tubes 2. In Figs. 3 and 4 the rebound surfaces 6a, 6b meet in a sloping line 14 which leads to an outlet 15 for the particles controlled by a counterweighted flap 16. Part of the flue gases and impurities are removed through an outlet 19, the main flue gas outlet 21 in the side 6b being convered by a grating.

Filed: 1948-02-29
Abstract: 656,566. Charging melting furnaces. TOLEDO ENGINEERING CO., Inc. Feb. 29,1948, No. 6356. Convention date, Aug. 15, 1946. [Class 51(ii)] Batch material is fed into a melting furnace through a conduit which extends through the upper surface of the molten mass in the furnace and is moved laterally of the furnace to distribute the e batch material beneath the surface of the molten mass. In the apparatus shown, a feed hopper 65 is positioned adjacent the charging opening 0 of the doghouse D of a glass-melting furnace and is vertically adjustable by means of a rack and pinion 66, 67 in supporting frame 30 mounted for oscillation about a vertical pivot 20 on a carriage 15 having wheels 16 running on horizontal tracks 12. The rear end of the frame is supported by a roller 37 running on an arcuate track 22 provided on the carriage and driven through gearing by an electric motor M, trip switches I being provided to effect reversal of the drive. The. front end of the frame may be raised or lowered relative to the pivot 20 by rotation of a threaded shaft 55 through chain and sprocket gearing. The lower end of the hopper communicates with an L-shaped discharge spout 80 through which the batch material is fed by a worm 83 driven through gearing by the motor M. The spout is pivoted to a bracket 95 on the frame 30 and is angularly adjustable by lengthening or shortening a link 100 connecting the worm gearbox to the bracket 95. A closure plate 115 is pivoted to a lug 119 on the spout and is angularly adjustable by a bolt 120. The upper edge 126 of this plate is radiused for engagement with a guide pin 125 depending from the carriage 15. The walls of the spout and plate are formed with chambers for the circulation of a cooling medium. The lower end of the spout, which is normally immersed in the molten glass, is formed by an expendable collar 112 welded in position. In operation, the position of the carriage 15 and the inclinations of the frame 30 and spout 80 are so adjusted that the lower end of the spout is suitably spaced from the walls of the furnace and immersed to a desired depth in the molten glass, the hopper 65 being raised or lowered to maintain its lower end in sealing engagement with the upper end of the spout. The motor M is then started to effect rotation of the worm and an arcuate movement of the hopper and spout, the batch material being thus distributed beneath the surface of the molten glass.

Title: A bundle tying machine
Inventor: WALTERS JOHN WALTER GRAY
IPC: B65B13/10
Filed: 1963-02-18
Abstract: 1,002,471. Bundling-machines. SHERIDAN SERVICE CO. Ltd. Feb. 14, 1964 [Feb. 18, 1963], No. 6439/63. Heading B8C. A bundle, e.g. of newspapers, is tied with tape in two directions normal to one another, the tape being tensioned around the bundle before it is overlapped, welded and cut above the weld. The machine is prepared by drawing tape from a reel 20 through a tensioning device 40 and a reciprocable tightening mechanism 44, into a gripper head 48, the tape then being drawn to the position shown in Fig. 15 by a pair of extensible draw arms 70, 72 having fingers 78, 80 respectively at their ends which pivot into engagement with the tape. Similar mechanism, Fig. 1 (not shown), operates on tape drawn from a second reel to tie the bundle cross-wise, both mechanisms operating together but not synchronously. Compressing and tying.-A bundle supplied to the tying position on a table 2 is compressed by means of a ram and piston 5, 7. A supply conveyer (not shown) is stopped when the bundle trips a switch, and drive is imparted to camshafts on which are discs controlling the actuation and timing of the tying movements. The draw arms 70, 72 are interconnected by crossbars 396, 430, Fig. 10, which, when latched together, hold reels 418 in engagement with the tape. On release of the latches, the reels pivot to the position shown in interrupted lines in Fig. 10. The tape is drawn about three sides of the bundle by the action of rollers 52 of the tensioning device 40, the rollers being mounted on a carriage spring-urged away from fixedly mounted rollers 50. The gripper head 48 descends to draw the tape along the fourth side of the bundle. The grip and release of the tape is effected by means of a cam-operated block and a pawl which is spring-urged to hold the tape against a face of the block, Figs. 7 and 9 (not shown). A pinion on the block engages a rack to rotate the block as the gripper head 48 descends, thereby turning the end of the tape horizontally. At its lowest point of travel the head 48 engages a forked member, Fig. 4 (a) (not shown), which moves a sleeve of the head horizontally under the bundle to overlap the free end of the tape with the portion already there. Gripper shoes, Fig. 3 (a) (not shown), of the tightening mechanism 44 close on the tape pulling it back round the bundle. The overlapped tape is gripped between an anvil and backing member, Fig. 9 (not shown), and heat applied to weld it together. The rising anvil trips a switch to temporarily disconnect the drive to the cam-shafts, thereby allowing the weld to set. After an interval, the sleeve of the head 48 is withdrawn and the tape cleared from the gripper head which is re-aligned to grip the tape lower down. The tape is then cut. The gripper head is raised to its initial position preparatory to the next machine cycle.

Title: Process of colour development in colour photography
IPC: G03C7/32
Filed: 1954-03-09
Abstract: 755,655. Photographic colour development. KODAK, Ltd. March 9, 1954 [March 13, 1953], No. 6768/54. Drawings to Specification. Class 98 (2). To reduce excessive graininess, sharpness and contrast of colour developed dye images without reduction of the silver salt content of the emulsion relative to black and white materials and without the loss of speed which' would be involved by use of a fine-grained type of emulsion, an exposed three layer colour-formd material is developed with a primary aromatic amino developer in the presence of an imageforming coupler and also of a competing coupler which gives a soluble dye image removable by washing without causing diffusion of the desired insoluble dye image. The competing coupler may be used either in one or more of the emulsion layers or in the developer. As illustrated with reference to three lots of fast coarse grained red-sensitive emulsion containing the coupler 2-(diamylphenoxyacetamido) - 4 : 6 - dichloro - 5 - methyl phenol dispersed by the method of Specification 541,589, the first with 30 mg. of silver halide per square foot on red exposure, normal direct colour development and silver removal gives a cyan image of normal contrast but undesired graininess, the second with 400 mg. per square foot on similar procedure gives an image of excessive contrast, while the third, similar in all respects to the second except for the addition of H acid as competing coupler to the colour developer, gives contrast as of the first emulsion but materially reduced graininess. In multilayer reversal procedure 1-naphthol- 3 : 6 : 8 - trisulphonic acid in the colour developer with two to four times the normal amount of silver halide in the emulsion produces superior results. The process is applicable to multilayer films containing coloured colour couplers, as of Specifications 599,377 and 617,247. Competing couplers other than the above are listed. Specifications 524,154, 524,554, 524,555 and 539,510 also are referred to.

Title: Improvements in and relating to methods and apparatus for folding and gluing of paperblanks for the manufacture of bags, pouches, envelopes and the like
IPC: B31B160/10
Filed: 1947-03-12
Abstract: 622,087. Paper bags. GASSMANN, W. March 12, 1947, No. 6885. Convention date March 15, 1946. [Class 94(ii)] Paper blanks 2 are formed into bags, pouches or envelopes by being passed around rolls 4, 10, 14, 16 provided with suction channels 11, 15, 17, 21, a pivoted suction arm 6, a folder 13 and a gluing strip 27. As shown, the arm 6 sucks off the lower blank, drawing it into the recess 7, the edge 8 of which afterwards contacts the back of the blank causing the latter to pass over the roller 3 and between rolls 4 and 9. An air stream may be directed against the upper edge of the pile 2 to help separation of the blanks. The suction in channel 11 becomes effective when the latter is at point of contact of roll 4 and roll 10, which is rubber covered. The vacuum in channel 11 then becomes ineffective and that in channel 15 effective, so that the blank is taken around the roll 14. The vacuum in channel 15 is cut off at 15<SP>1</SP> and that of the channel 17 (now at point of contact of rolls 14, 16) effective. The forward edge of the blank is then folded over just in front of the suction channels 17, then folded down backwards by means of the roller 22 and finally, when passing the latter, completely folded over. Suction channels 21, in arms 20, which may be angularly adjusted relatively to the roll 16, also suck at the blank along its centre line. A narrow strip of glue is applied by the strip 27 to the rear end of the blank. The suction in channel 17 is then reversed so that the forward end of the blank is blown off. The latter, with its previously folded forward edge, enters the space formed by a fixed guiding plate 31 and a pivotable plate 33 when positioned as shown dotted. The plate 33 now moves towards the plate 31 to hold the front of the blank. A fold is now formed along the centre line of the blank by a roller 29, the glued strip on the rear end being pressed on to the front edge. The flat tube is then fed into a device 34 where, in known manner, the bottom is closed on one side and a closing flap folded over the bag top. At the start, to prevent glue being applied to the uncovered roll 16, the latter may be fitted with a notch which faces the end of the strip 27, or the roll 28 may be moved clear of the roll 16.
