Title: Laminate and method of manufacture
IPC: C09J7/22
Filed: 1966-01-18
Abstract: 1,128,477. Laminates. WELLINGTON PRINT WORKS, Inc. 18 Jan., 1966 [21 Jan., 1965], No. 2243/66. Heading B5N. A decorative laminate comprises a plastics sheet 12 having printing on one side, an adhesive layer 18 on one side ofthe sheet 12, and a plastics backing 14 in coextensive and facing relation to the layer 18 and temporarily secured to the sheet 12 by the adhesive layer 18, the sheet 12 and backing 14 having been stretched to a similar extent from their normal conditions prior to being secured by the adhesive layer. In a method described for making the laminate, the sheet 12, of e.g. polyvinyl, having decoration 16 on one face, is fed from an unwind roller, via a preheat roller and tensioning rollers, to an adhesive applying station, where the adhesive layer 18 is applied to the other face of the sheet by an engraved roller. The adhesive coated sheet is then fed via a curing tunnel, where the adhesive is dried by hot air, to a pair of combining rollers, where the backing 14 is applied, the laminate so formed being slit longitudinally on its way to a rewind roller. The backing 14, which is of e.g. polyethylene, and which has previously been treated to receive printing by exposure to an electric spark gap or discharge or by electrostatic etching, and has also previously been printed and embossed, is fed to the above mentioned combining rollers from an unwind roller via a preheat roller, stretching rollers, and a slitting roller which forms perforations 22. The embossing, which is preferably longitudinal, reduces the area of contact of the backing and the adhesive layer, and facilitates stripping of the backing, as also do the perforations 22. The printing on the backing may be instructions 20 and/or length indications.

Abstract: 371,442. Slotted wings. PAGE, F. H: and PAGE, Ltd., H., 40, Claremont Road, Cricklewood, London. Jan. 23, 1931, No. 2290.[Class 4.] In aircraft wings of the type having automatic slats connected to pivoted flaps in such a manner that each flap is angularly adjusted to a high incidence position when its slat moves away from the wing and is returned to a small incidence position when its slat moves towards the wing, the connecting mechanism is so constructed as to prevent the flap when in its high incidence position from moving the slat to close the slot. In one form, Fig. 2, a slat b is connected to a flap c through toggle levers d<1>, d<2> which are pivotally connected at d<5>, and of which the lever d<1> is pivoted at d<3>. The arrangement is such that as the slat advances and pulls down the flap c the toggle parts d<1>, d<2> cross over dead points preventing the flap from overpowering the slat. In a modification the connecting members comprise an eccentric rotated by movement of the slat and operating the flap through an eccentric strap. In the full-open position of the slat the eccentric is past the dead-centre point and the flap is ineffective to move the slat. In a further modification, Figs. 5, 7, and 9, pawl and ratchet mechanism is employed to lock the flap in its adjusted position until moved therefrom by the slat. Coaxially mounted levers f<3>, g<3> are connected to slat and flap respectively and are interconnected through stops g<4>, g<5> permitting a certain amount of lost motion. Lever g<3> carries a spring-pressed pawl h<2> engaging with a fixed ratchet h<3>. Fig 9 shows the mechanism with the slat fully open and the flap locked, Fig. 7 shows how the pawl h2 is released on backward movement of the slat by means of an extension f<5> of the lever f<3>. According to the Provisional Specification a release mechanism may. be interposed between the slat and the flap which may be automatically or manually operated when the flap tends to overcome the slat and may provide for elongation or release of the connecting links.

Abstract: 1343302 Control systems for consuming apparatus SOC ANON FRANCAISE DU FERODO 19 Jan 1971 [21 Jan 1970] 2704/71 Heading H2H Apparatus for controlling a plurality of thyristors arranged in groups for controlling the current supplied to a load comprising a plurality of partial loads or to a plurality of loads comprises means for reducing the possibility of the thyristors conducting simultaneously. Conductors 10A, 10B, 10C are connected to a group of three thyristors controlling the current flowing in a three phase load and corresponding conductors are provided to control the current in other loads, the number of which corresponds to the number of conductors C from a selector device 15. The firing pulses for the thyristors are developed from a source 11 of voltage, proportional to the desired load current, by way of a sawtooth generator 12 and pulse generator 13. The train of pulses dp from the generator 13 are fed to the rotary selector device 15, each pulse being delivered to one of the conductors C and then stepped on one stud P. After distribution by the device 15 each pulse is fed to a memory device 16 and thence to AND gates 18 and shaping circuits 20 finally to the firing conductors 10 for the group of thyristors. In order to ensure that the thyristors fire at the zero points of the supply voltage pulse generators 23 are provided to generate pulses at the zero points which are then fed to the second inputs of the AND gates 18 to allow the firing pulses to pass these gates. The output pulses from the shaping circuits 2 are also fed to an OR gate 22 and used for resetting the memory device 16. Thus each group of thyristors is fired as a pulse is delivered to the conductors C 1 , C 2  ..... C n . Other embodiments are described wherein each group of thyristors is controlled by an individual pulse generator 13, and in which the supply is single phase.

Title: Apparatus for applying adhesive
IPC: A43D25/18
Filed: 1945-02-05
Abstract: Apparatus for applying fluid adhesive simultaneously to two surfaces of a workpiece, specifically a sole element and the wrapper portion of a shoe upper, comprises a nozzle, means for advancing the workpiece relatively to the nozzle and means for supplying the adhesive under pressure to the nozzle.  The nozzle has a narrow and elongate delivery orifice in each of the two adjacent work-contacting surfaces.  A slide 16, Figs. 1 and 6, is provided with a bracket arm 28 which receives the nozzle 30.  In the shaft 42 is a tube leading from the nozzle through a supply conduit, a pressure gauge and pump to the adhesive container 41. A shaft 23 connected with the drive shaft 9 carries on its lower end a work-advancing roll 26.  The parts are so arranged that when the <PICT:0588203/III/1> <PICT:0588203/III/2> <PICT:0588203/III/3> <PICT:0588203/III/4> nozzle is applied to the work and to the roll by rearward movement of slide 16, adhesive is permitted to flow through to the nozzle. By forward movement of the slide the flow is automatically stopped.  The nozzle has an internal chamber 50, Fig. 11, and a work-engaging surface 51 provided with a vertical delivery orifice 53 and of which one marginal wall is notched to provide distributing ribs 54.  The bottom surface is similar.  Ports 57 and 58 communicate between the chambers 50 and orifices 53 and 55. The adjacent ends of the orifices are so spaced as to avoid delivery of adhesive into the angle where the sole and upper meet. Alternative nozzles are illustrated which by use of interchangeable plates provide orifices of different widths and/or lengths.  The adhesive container 41 is provided with a leak-tight nipple 69, on the inner surface of which, behind a thin septum, is secured an elastic diaphragm furnished with an aperture.  When placed in position, Fig. 16, the bracket 84 which carries a sharp-pointed cannula is swung up into position, and the tapering end pierces the septum and fits snugly in the aperture.  Fig. 6 illustrates the machine in operation on a force-lasted shoe.  The wrapper W is gripped between the roll and the nozzle, the roll tending to straighten the wrapper as it advances the shoe, and the adhesive is deposited as ribbons on the inner surface of the wrapper W and on the margin of the middle sole M.  In a modification, the roll 127, Fig. 22, having a rim preferably of yieldable material such as rubber, has a helical rib and is of frusto-conical shape.  This is fitted with a tubular shaft carrying a guide-roll 132 <PICT:0588203/III/5> <PICT:0588203/III/6> and in addition to advancing the work exerts an upward pull on the upper.  The machine may also be provided with a plough arranged in front of the guide roll to turn the wrapper up to the upright position ready to receive the adhesive.
