Title: Method and apparatus for coating web material
Inventor: SMITH ROBERT LEWIS
IPC: B05C1/10
Filed: 1965-04-08
Abstract: A method of coating a web with adhesive in the form of separate dots comprises passing the material around a roller adjacent a source of powdered thermoplastic resin, providing an electrostatic potential difference between the conducting spindle of the roller, formed of insulating material, and the resin source, the roller surface including a pattern of spots of conductive material each electrically connected to the spindle, and subsequently heating the material to fuse the resin to the material.  If the material comprises synthetic fibres e.g. rayon or nylon, it is necessary to subject it to an antistatic treatment prior to coating to ensure the resin only adheres to those portions adjacent the spots of conductive material. Examples of thermoplastic resin given are polyethylene, polypropylene copolymer of ethlene and propylene or an E.V.A. resin (copolymer of ethylene and vinyl acetate).  The roller preferably comprises a wooden roller mounted on a metal spindle, the wooden roller having radial holes drilled therein, and in each hole, a wire connected to the spindle, the end of the wire at the roller surface forming the conductive spot.  The source of powdered thermoplastic resin may be a fluidised bed, an electrode being inserted into the container to provide the electrostatic potential difference.  Alternatively the source may be a spray gun which scans the width of the roller.  The resin may be cured by infra-red heaters.  The product may be immediately laminated with other layers or cooled and subsequently laminated. The product is intended for use as an 'iron-on' material.

Title: Improved machine for sealing cartons
IPC: B65B7/20
Filed: 1948-06-04
Abstract: 649,355. Closing cartons. McTAGGART, J. H., and ROSS, D. T. June 4, 1948, No. 15102. Convention date, July  23, 1947. [Class 94(i)] A machine for sealing cartons comprises a feed-in carton race and a feed-out carton race disposed approximately at right angles to each other, reciprocating means to move a carton along the feedin race, means associated with the feed-in race to hold the two inner flaps of the carton closed, glueing means adjacent to the feed-in race adapted to render adhesive both sides of one outer flap of the carton, further reciprocating means to move said carton into the feed-out race,when it reaches the end of its movement along the feed-in race and means to close the glued outer flap between the closed` inner flaps and the unglued outer flap and means to close the unglued outer flap over the glued outer flap as the carton moves into the feed-out race. A carton 99, closed at the bottom and with its inner top flap folded, is placed on a feed-in race 6, comprising an inclined back plate 10 and a floor 12 perpendicular thereto, in front of a reciprocating pusher plate 51 which then engages the side of the carton and pushes it along the feed-in race with its outer flaps 102, 103, Fig. 2, disposed on either side of a retaining arm 56, extending along the feed-in race, which holds the inner flap closed. The flap 102 is turned outwardly by a deflector 57 and is directed between glueing rollers 46, 47, the peripheral speed of which is preferably slightly greater than that of the pusher 51, the rollers glueing both sides of the flap. The glued flap 102 is then turned inwardly by a deflector 59 and the unglued flap 103 by a deflecter 105 to positions shown in Fig. 3, when the pusher 51, at the end of its stroke, pushes the carton into an inclined entrance portion 28 of the floor of a feedout race 7. A pusher 37 then advances and pushes the carton erect and into the feed-out' race; during this movement an arm 39 moves down as the frame 38 carrying the pusher 37 moves forward and a head 44 on the arm 39 closes the glued flap 102. A curved inner end 36 of a pressure plate 35 extending along the top of the feed-out race 7 then engages the unglued flap 103 and folds it down over the flap 102, the glue on the flap 102 securing all four, two inner and two outer, flaps together. The pusher plate 37 moves the carton into the feed-out race 7 a distance sufficient to allow the passage of a succeeding carton from the feed-in race. In operation the feed-out race is normally filled and as one carton is pushed in at one end the opposite end carton is forced out. The time taken for one carton to pass through the feed-out race is sufficient for heating means 30, secured to the back of the pressure plate 35 and with it adustable vertically, to cause the adhesive to set. The pushers 51, 37 are reciprocated in timed relationship by a series of cranks and levers driven from an electric motor which also drives the glueing rollers 46, 47, the upper roller 47 being mounted to yield slightly in an upward direction.

Abstract: 705,482. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. May 19, 1950 [July 7, 1949], No. 15187/49. Class 106 (1). [Also in Group XL(c)] A digital computer including an electrostatic storage device comprising an insulator arranged to be scanned by an electron beam to set up at discrete areas on the insulator charge distributions representative of information to be stored, the scanning action being such that pauses occur during which the beam is held stationary, is characterized by the provision of means for switching off the electron beam for part of each pause. After reading a digit (i.e. either a "dot = 0" or a " dash = 1 ") recorded on a CRT memory tube, a finite time elapses before the digit to be recorded in the same data position is determined by the computer, and since it is undesirable to keep the electron beam on the one spot longer than (say) two microseconds, a so-called "meditation pulse is arranged to switch off the beam for a predetermined period. Negative-going " dot " pulses from a suitable generator are applied continuously via a diode D16 to cut off a valve V13, causing positive pulses, limited to a peak of 50 volts by the action of a diode D17, to be passed to a cathode follower V14 supplying the grid of the memory tube. Meditation pulses, coming down to 20 volts, are passed through the diode D17 shortly afterwards, causing the CRT beam to be cut off. Other arrangements for applying the meditation pulses are described, and the following Specifications are referred to:- 645,691, 657,591, 682,156 and 705,474.

Title: Adjusting the rental charge in prepayment mechanism
IPC: G07F15/08
Filed: 1945-06-18
Abstract: 594,264. Prepayment mechanism for meters. ENGLISH ELECTRIC CO., Ltd., and WHITEHEAD, R. K. June 18, 1945, No. 15451. [Class 27] Mechanism for varying the rental charge, and included in the drive from a constant speed motor to the prepayment differential, comprises a single adjusting knob for effecting adjustment in steps of a unit (e.g., a halfpenny) and multiples of such unit (e.g., a shilling) in combination with a unit step adjustable transmission comprising a positive clutch engaged and dsengaged at two relatively adjustable points in each revolution. As shown the driving member of the units clutch comprises a spring loaded pin 4a carried by an axially movable gear 4 driven by a pinion 3 from the constant speed motor. The driven member is a wheel 7 having a ring of holes 7a for engagement by the pin 4a. Control of the clutch is effected by a disc 1 fast with the gear 4 and provided with a projection lb and a notch la, a pin 5 on a normally stationary adjustment disc 9 lying in the path of the projection lb. When the projection lb reaches the pin 5 as the disc 1 rotates the disc, and with it the wheel 4, is displaced axially to engage the pin 4a in a hole 7a of wheel 7, this position being maintained against a return spring 2, as the projection clears the pin, by a catch 6 which snaps behind the disc 1 to hold it. Subsequently the notch la in the disc comes up to the catch 6 so that the disc is released and the clutch pin 4a disengaged from wheel 7. The position of pin 5 relative to catch 6 determines the unit charge, and this can be adjusted by rotating disc 9 by means of a screwdriver slot 5b in its boss. The multiple unit drive is substantially identical, and comprises corresponding driving and driven clutch parts 14a, 17 controlled by an adjustment disc 19. This adjustment disc is rotated through one step, at each revolution of the units disc 9, by engagement of a pin 9b of the disc 9 with teeth 19a. Thus, by the rotation of disc 9 through a number of revolutions, adjustment through the complete range of the twin transmission mechanism is effected. The two driven clutch members 7, 17 are connected through summating mechanism to the prepayment differential. The clutch may be engaged more than once in each revoution, with appropriate modification of the transmission from disc 9 to disc 19. To cover a wider range, more than two transmissions, as above, may be provided. Indicators.-The fine and coarse price-adjustment discs 9, 19 are appropriately graduated, e.g., in pence and shillings, with the operative figures visible side by side through a window.

Title: Improvements relating to the production of pattern effects on textile fabrics
IPC: D06Q1/02
Filed: 1940-10-28
Abstract: 544,820. Artificial silk ; treating textiles with liquids ; dyeing processes. HARDACRE, R. W., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. Oct. 28, 1940, No. 15745. [Classes 2 (ii) and 15 (ii)]  Textile fabrics composed of synthetic linear polyamides are crimped by locally treating them, e.g. by printing, with an aqueous medium having a swelling effect and containing zinc chloride or a metallic thiocyanate, removing water from the locally treated portions, and then steaming. The printed portions of the fabrics are endowed with an increased affinity for direct, azoic, vat, and cellulose acetate dyestuffs. The polyamides may be derived from monoamino monocarboxylic acids or their lactams, e.g. 6-amino-caproic, 7-aminoheptanoic, or 11-amino-undecanoic acid, or from diamines and dicarboxylic acids examples of such polyamides being polytetramethylene sebacamide, polyhexamethylene adipamide, and polyhexamethylene sebacamide. The filaments may be obtained by melt spinning and may be cold drawn. Calcium or zinc thiocyanate may be used as swelling agent. The fabric may be printed with the aqueous solution of metallic salt, dried, steamed at 100‹C. whilst in tensionless condition, washed, and dried in tensionless state. If desired the fabric may first be printed with a resist such as starch paste or gum and then immersed in the metallic salt solution. The salt solution may contain a thickener such as gum senegal and a wetting agent. Dyes may also be included in the salt solution but it is preferred to dye the fabric after treatment with the salt solution. In an example, polyhexamethylene adipamide is printed with a paste made by mixing calcium thiocyanate solution, gum senegal solution, water, and the substance sold under the Registered Trade Mark " Perminal K B." The fabric is dried, steamed without tension, washed, and dried without tension. The printed portions shrink and the fabric becomes crinkled. On dyeing with " Chlorazol " Yellow R.S., the printed portions dye a deep yellow whereas the unprinted portions are practically untinted. Specifications 461,236, 461,237, 474,999, and 495,790, are referred to.
