Title: Method of and apparatus for forming and covering fibrous pads
IPC: B65B9/02
Filed: 1958-02-19
Abstract: 884,196. Production of fibrous pads. JOA, C. G. Feb. 18, 1959 [Feb. 19, 1958], No. 5277/59. Divided out of 884,195. Class 96. Waste fibrous material is defibrated in a hammer mill, pneumatically conveyed to a volumetric feeder, picked up by a rising conveyer acting with suction to form continuous fibrous strips 52 which are trimmed to the required thickness and width, e.g. as disclosed in Specifications 884,191 and 884,193. The strips 52 pass to a wide conveyer 46 and are compacted by a belt 5 and divided into pad portions with the aid of a hood 7 or a hood 7A according to the length of pad required, one hood 7 being fixed relatively to a carriage 23 and the other 7A being movable. A drum cam 21 is rotated by a shaft 22 which also carries switch units controlling suction and compressed air supplies to the hoods 7, 7A to remove portions of the strips 52 to effect the subdivision thereof into batts. The batts pass across a gap 10 to a conveyer 47, where they are covered by paper webs 11, 12, the latter being glue-coated at 13 so that the batts adhere thereto, as does also the upper web 11, when pressed thereon by rollers 14 and by bars 16, 16A which reciprocate above a conveyer 49. The assemblage is divided longitudinally by rotary knives 17A, and transversely by a serrated, rotary knife 18 as disclosed in Specification 884,194 to leave projecting, frayed, fibrous edges, so that e.g. polished furniture is not scratched if packaged with such pads. An adhesive which is pliable after setting may be used for the same reason. In a modification, only one hood of inverted U-shaped cross-section is used instead of the hoods 7, 7A, and such a hood may remove a portion of the fibrous material in four equal parts. A network of rollers may be used for impressing corrugations in the upper web 11. Specifications 884,197 and 884,201 also are referred to.

[Also in Divisions G5 and H1] A magnetic tape 3 in the form of a magnetite layer coated with a thermoplastic adhesive and mounted on a carrier is fed over an electrically heated roller 22 before being applied to a cinematograph film 2 to which a solvent has previously been applied by a device 25, the carrier being stripped off subsequently. The supply and take-up spools 4 and 9 for the film are belt driven, and the tension of the film is kept constant by band brakes 15 acting on the spools and controlled by a lever 18 which carries a roller 19 bearing on the film on spool 4. The roller 22 is maintained at a constant adjustable temperature, e.g. about 130‹ C., to make the thermoplastic layer liquid and tacky, and a roller 43 presses on the driving roller 7 to press dust particles on the film or tape into the adhesive layer. A guide pin 23 is adjustable to alter the position of the tape on the film, and the position can be observed by a microscope 44. The tape may be applied to one or both edges of the film. The adhesive may be acetyl cellulose, and the carrier may be a polyester which sticks to the acetyl cellulose only by adhesion so that it may be stripped off easily.

Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M25/14
Filed: 1948-02-24
Abstract: 660,262. Spray carburetters. CARTER CARBURETOR CORPORATION. Feb. 24, 1948 [Feb. 3,1942], No. 5519/48. Class 7(iii) In a carburetter, valves 16, 29, normally held closed by suction in the induction pipe 7 acting through pipes 19, 32 on pistons 17, 30, open when the suction decreases to allow extra fuel from chamber 9 and antidetonating liquid e.g. water or alcohol from chamber 25 to flow to nozzles 12, 28 respectively to reduce detonation. A choke valve 34 is held closed at starting by a thermostat 35, in which position a pipe 33 supplies air directly to the nozzle 28 and prevents antidetonant being sucked therefrom. When the valve 34 closes after warming up, its upper part closes the pipe 33 and antidetonant can then be sucked from the nozzle 28 when the valve 29 opens. A pump 42 is actuated by the drop in suction in the pipe 7, when the throttle valve is opened for accelleration, to force antidetonant through a nozzle 48. A pivoted vane 50 is actuated by a spring-pressed piston 53 subject to the suction in the pipe 7. Specification 412.597, [Group XXXV], is referred to. The Specification as open to inspection under Sect. 91 states also that exhaust gases may be used as the antidetonant, in which case the means supplying anti-detonant liquid through the nozzle 28 is replaced by a pipe leading to the induction pipe 7 from the exhaust pipe and controlled by a suction actuated valve similar to the valve 29. This subject-matter is not included in the Specification as accepted.

Abstract: 780,446. Making furnace walls. COMBUSTION ENGINEERING, Inc. Feb. 24, 1955 [Sept. 14, 1954], No. 5547/55. Class 83 (2). [Also in Group XII] A method of constructing a wall 12, Fig. 2, comprised of parallel tubes 14, particularly a fluid-cooled furnace wall, comprises forming at least two tube panels 36a, 36b, 36c, each composed of a plurality of parallel tubes secured to each other, raising said panels into the desired wall position with the tube ends of one panel abutting and aligned with the tube ends of an adjacent panel, and welding the tube ends of one panel to the corresponding tube ends of the adjacent panels as at 38, Figs. 1, 6. A watercooled furnace 10, Fig. 1, of a steam generator, comprises tubular walls 12a, 12b, 12c, each made up of panels such as 36a. The tubes of each panel are welded together at 44 approximately at their mid-spans and the panel is bent where necessary, such as at 54, to conform to the desired shape of the furnace walls. These operations are performed in the workshop. The panels are then despatched to the erection site and adjacent panels such as 36a; 36b, Fig. 6, are assembled together by means of jigs 64, 66, each comprising a pair of channel-section beams 68, Fig. 7, with lugs 70 spaced to engage alternate tubes 42, 42b, of the panel. The two beams are pulled together by diagonal bolts 80, 82, whereby the ends of the tubes are sprung out of the general plane of the panels to permit access all round the tube ends for welding. The two jigs 64, 66 having been assembled on the adjacent ends of the two panels 36a, 36b, Fig. 6, are secured together by bolts 78 whereby the tube ends of the two panels are aligned with each other. The panels are then positioned in the furnace walls and the adjacent tube ends are welded together at 38. Upon removal of the jigs, the tube ends return to their original parallel position. For transit, and also if desired during bending, the tubes forming a panel are additionally held together by straps 46, 48, Fig. 4 (not shown), and the ends of the tubes are protected by channels.

Title: Improvements in or relating to locking devices associated with nuts and other internally screw-threaded parts
IPC: F16B39/32
Filed: 1944-03-28
Abstract: 575,591. Locking nuts &c. HOY & CO., Ltd., A., and PROCTOR, S. E. March 28, 1944, No. 5723. Addition to 563,437. [Class 89 (i)] Instead of cutting away part of the thread of the screw to receive a locking wire as in the parent Specification part of the thread is removed from the nut or equivalent member. The thread is removed to about the depth of its root diameter forming a groove 4, Fig. 2, extending from a hole 1 to a hole 2 about 270 degrees apart. The ends of the wire are bent to engage in the holes, the length of the curved portion being such that when the end 6 engages the side of the hole as shown there is clearance x on either side of the end 7. The part 5 is bent to a radius less than that of the screw and in this form the action of the nut is to decrease the frictional grip of the wire both during screwing-up and unscrewing. The backlash x may be eliminated, if both ends of the wire contact the holes as shown in Fig. 3 the grip of the spring is increased in both directions of rotation but if the ends contact the opposite sides of the holes then the grip is relieved. In a further modification the ends of the wire 8 engage abutments 12 formed in a separate ring secured in a reduced end 11 of the nut. One end only of the ring may be anchored. The cross-section of the ring may be such as to fit the thread or to engage it at the sides only and it may be deformed laterally to increase the pressure on the threads.
