Title: Method of and apparatus for manufacturing open containers made of pliable sheet material
IPC: B31B3/28
Filed: 1940-06-24
Abstract: 542,244. Making containers of flimsy material BEE BEE BISCUITS, Ltd., and BUXBAUM, E. K. June 24, 1940, No. 10814. [Classes 18 and 94 (ii)] Open containers are made from flimsy material such as thin sheets of cellulose derivatives, waxed paper, metal foil, tissue paper &c. by mechanically folding the sheet about the base and sides of a forming block, causing the folds to adhere at least to each other and stripping the formed container from the block by pressure applied to the inner surface. The sheet A, Fig. 3, is positioned on a plate 2 beneath a block 5, its sides turned up by hinged plates 4, the block moved through a die 1 to turn the remaining sides up and the folds thus formed laid against the sides by folders 9, 10, one of which may have an electric heating element at 13 if an adhesive requiring heat is used. The container is stripped from the block 5 by a frame 15, Fig. 7, carried on rods 18 which pass through the block and are actuated by a lever 19, return movement being effected by springs 16. Means for dispensing adhesive may be associated with a part of the table bounding the die aperture. The sides of the container may be held against the forming block by suction applied through holes in the sides of the block. A modification is described in which sheet material, e.g. thin cellulose acetate, is fed from a roll 70, Fig. 12, between rubber or covered friction rolls 72, and is cut by a blade 81 actuated by a cam 83. The web is positively positioned by two suction heads 93, these being connected to a suction main 100 and moving with the web, the required motion being derived from a cam 84 through roller 113, rod 111, lever 109 and rods 105. Curved guard rods 101 prevent lateral sagging and leaf springs bear on the web and prevent it from being lifted by the cutter. Specification 542,148 is referred to.
Patent GB-1090732-A (GB)
Title: Method of producing plastics mats and mats produced by said method
IPC: C08J9/36
Filed: 1963-03-19
Abstract: Mats are made by screen printing one or more layers of a thermoplastic plastisol, of e.g. PVC or polythene, over discrete areas of a flat matt surfaced support, applying an overall backing layer, either as a plastisol or as a preformed layer, or as both in combination, heating the composite thus formed to gell and bond it, and finally removing the finished mat from the support.  The plastisols used for the screen printing may have a lower plasticizer content than that used for the backing thus giving a mat with a hard decorative upper surface and a soft non slip undersurface.  The preformed layer may be a foam polyester, polyether, or polyurethene.

Title: Conveying of a slurry through a pipeline
IPC: B65G53/30
Filed: 1959-04-01
Abstract: 861,537. Conveying solids in a liquid. CONSOLIDATION COAL CO. April 1, 1959 [April 14, 1958], No. 11003/59. Drawings to Specification. Class 102(2). In a pipeline system through which solids such as coal are conveyed by mixing the solids with a liquid to form a slurry, the pipeline is filled with liquid prior to the introduction of the slurry and as the slurry is pumped through the pipe some of the solids mixing with the liquid and tend to settle. The solids settling at the front of the slurry are subsequently remixed with the slurry passing over them forming a zone of high solid concentration which results in a high pressure drop while the solids settling at the back of the slurry remain in the pipe. To avoid these two conditions the present invention provides a slug of pseudo fluid having a solids suspending property greater than the liquid of the slurry at either end of the body of the slurry and the solids from the slurry mixing with this pseudo fluid slug are carried through the pipe without settling. The slug is preferably formed by mixing finer particles of the solid being transported in the liquid medium.
Patent GB-436529-A (GB)
Title: Improved inking mechanism for the ribbons of typing machines
IPC: B41J31/16
Filed: 1934-04-12
Abstract: 436,529. Ink - ribbon mechanism. ALEXANDER, P. S. H., 25, Stirling Road, Edgbaston, Birmingham.-(Pelton, G. E. ; Popkin's Farm, Alexandria, Virginia, U.S.A.) April 12, 1934, Nos. 11047 and 14118. [Class 100 (iv)] In mechanism comprising a thin disc for supplying a film of ink to the ink ribbon of typewriting-machines, the disc contacts with the ink ribbon as a part thereof which is otherwise out of contact with the mechanism. The arrangement prolongs contact between the disc and ink ribbon, and thereby prevents the disc from wearing or cutting the ink ribbon, and also prevents the film from being ruptured by vibration. The mechanism may be employed also for supplying ink to a ribbon which runs in contact with the ink ribbon. In the mechanism shown in Fig. 2, a two-colour ribbon 10 is guided around approximately half the circumference of a roller 28 and receives ink-films of different colours from discs or rings 24, 25 which are housed in grooves 26, 27 and project slightly beyond the periphery. Discs 21, 22, running in contact with the discs 24, 25, receive ink from wicks 18 and rest on wicks 16 dipping into inkwells 14. To prevent ink from spreading, the roller is knurled and formed with a middle groove 37, and the discs 24, 25 are arranged out of contact with the walls of the grooves 26, 27. The roller is geared to the shaft 23 of the discs 21, 22, and ball bearings 33 are provided. The vents of the inkwells may be provided with valves which are closed by pendulums when the machine is tilted. The wicks 18 are mounted in tubes 19 which can slide frictionally in housings 20, and the ends of the wicks are preferably flared. The roller 28 may be made in sections to permit changing of the discs. The inking surface of the discs may consist of type-metal or fibre. Duplicate mechanisms, each arranged rear one of the ribbon-spools, may be provided. In another construction, the ribbon passes around a roller geared to the ribbon-spool and formed with a groove containing a disc running in contact with an absorbent disc connected to an absorbent cylinder which is geared to the roller and dips into an inkwell. In the mechanism shown in Fig. 3, the ribbon 10 passes around a roller 41 and receives ink from a disc 40, the roller being formed with a circumferential groove in register with the disc, and the disc being arranged to touch the ribbon at or near its point of tangency to the roller. The disc is geared to the roller and to another roller 43 which receives ink from a wick 44. In another construction, a disc applies ink to a straight stretch of ribbon passing along a guide which is formed with a slot in register with the disc. Specifications 309,027, [Class 100 (iv)], 410,655, and 422,289 are referred to.

Title: Constant speed propeller simulating means for aviation trainer
IPC: G09B9/16
Filed: 1944-06-09
Abstract: 587,779. Apparatus for training pilots. LINK AVIATION DEVICES, Inc. June 9, 1944, No. 11112. Convention date, July 31, 1943. [Class 4] A ground trainer is provided with means for simulating the functioning of the manifold pressure gauge and tachometer in an aircraft fitted with a constant speed airscrew, the manifold gauge being caused to register in accordance with the setting of a dummy throttle control member, and the tachometer in accordance with the setting of a dummy airscrew governor control member. The invention is shown applied to a trainer of the type described in Specification 370,128 incorporating a dummy airspeed indicator 60, and dummy altimeter 142 and vertical speed indicator 144 mounted on a pressure tank 138, operated by movements of the fuselage and dummy throttle lever 92 as described in Specification 481,375. The dummy manifold gauge 232 and tachometer 290 are in communication with bellows 214, 288 connected to a source of reduced pressure and operated by the movements of the dummy throttle lever 92 and air-- screw governor control 242 respectively. Included in the mechanism operating the manifold gauge is a compensating bellows 204 in communication by a pipe 240 with the pressure tank 138, whereby the effect of altitude on manifold pressure may be simulated. The manifold gauge and tachometer actuating mechanisms are interconnected by a link 268 provided with a stop 272 permitting a degree of lost motion between the link and a bell crank 96 connected to the throttle lever, whereby movement of the latter to a position corresponding to an engine power below the range which the airscrew governor can effectively control results in appropriate variation of the tachometer reading. The airscrew governor control mechanism includes a bell crank 246, to which is connected a link 300 which, through an intermediate link 310, causes appropriate variation of the manifold gauge indication when the governor lever 242 is moved. A link 194 operates the manifold gauge and tachometer when the fuselage moves about the pitching axis, to simulate the effect on the manifold pressure and engine speed of diving and climbing. Specifications 569,248 and 573,953 also are referred to.

Abstract: 976,861. Machines with permanent magnets; A.C. commutator machines. LAURENCE, SCOTT & ELECTROMOTORS Ltd., and B. J. MASE. May 31, 1961 [March 30, 1960], No. 11148/60. Heading H2A. A tachogenerator comprises a body member provided with means for attachment to an anchoring device, a permanent magnet 4 fixedly mounted on the body member, an armature encircling the magnet 4 rotatably mounted on the body member for rotation about the magnet and coupled to a shaft the speed of rotation of which is to be measured, a commutator 16 rotatable with the armature and connected to the armature windings 14 and brushes 22 mounted on the body member and coacting with the commutator to provide electrical output leads from the commutator and thus the armature. The stationary body member comprises a main shaft divided into three sections 1a 1b 1c of different cross-section, an end plate 9 to which the magnet shaft 1 is keyed and a brush gear housing 11. Armature windings 14 are mounted within a cylindrical armature housing 12 built up from an end cap 12a a spacer 12b and an end cap 12c, the end cap 12a being shaped for attachment to the shaft the speed of which is to be measured and the end cap 12c being integrally formed with a sleeve portion 15 which surrounds the shaft portion 1a and carries the commutator 16. Connecting leads between the armature windings 14 and the commutator bars pass through holes in the end cap 12c and commutator spacing washer 16a which with the commutator is locked against rotation relative to the sleeve 15. The brush gear housing 11 fits about a boss 9a on the end plate 9 which is circular and coaxial with the shaft 1 so that orientations of the brush gear housing relative to the magnet 4 can be varied. In order that the body portion remains stationary the end plate 9 is held in position against rotation by clamping to a metal strip 26 formed with an anchorage hole 29. In operation leads are taken from the two brush holders 20 to a voltmeter the reading of which provides an indication of the speed of rotation of the shaft. Variations in magnetic flux density due to changes of temperature may be compensated for by means of a variable temperature sensitive resistance coil wound around the magnet shaft.
