Title: Method of Producing Laminates
Inventor: RATNER BENJAMIN MAX
IPC: B32B27/00
Filed: 1967-05-26
Abstract: 1,168,539. Laminate. DISPRO Ltd. 13 May, 1968 [26 May, 1967], No. 24527/67. Heading B5N. A process for laminating an aperture-containing substrate to a film comprises applying a solution of an adhesive directly to the film, partially removing the solvent in the solution, laminating the film to the substrate, and subjecting the film to a treatment which renders non-adhesive the adhesive on that part of the film covering the aperture. The substrate may be of paper, paperboard, synthetic resin or synthetic resin-coated paper or paperboard, and the film may be of oriented polypropylene, cellulose acetate, PVC or polyethylene terephthalate. The adhesive may be rendered non- adhesive by subjecting it to elevated temperature, e.g. hot air, or by curing it using ultraviolet radiation. In one example an adhesive consisting of an isocyanate polyester and an isocyanate curing agent dissolved in ethyl acetate is applied to a film of oriented polypropylene. The adhesive is subjected to controlled evaporation to render it tacky, and the film is combined with an aperture-containing board prior to passage through a heated nip. The adhesive over the aperture is then allowed to cure, or cured at an elevated temperature. The laminate may be used in envelopes or boxes.
Patent GB-203192-A (GB)
Title: Improvements in stop-mechanism for sound-reproducing machines
IPC: G11B17/02
Filed: 1922-09-11
Abstract: 203,192. Hopkins, L. S. Sept. 11, 1922. Brakes.-Relates to stop-mechanism of the kind in which automatic application of the brake is effected by cessation of the travel of the tone-arm. According to the invention, the brake-bar carries a star-wheel which is normally rotated by the turntable spindle, but is prevented from rotation when the tone-arm stops, whereupon the pressure exerted on the star-wheel by the spindle causes the brake to be released and applied. In the construction shown, a bar 17 carrying a brakepad 20 has a star-wheel 33 pivoted thereon, and also bears a lever 36 on which is a pad 37 adapted to engage frictionally a bow spring 15 mounted on an arm 11 carried by the tone-arm. Screws 23, 25 project through slots 21, 22 in the bar 17, the brake being held inoperative when the screw 25 is in engagement with the offset end of the slot 22. As the turntable spindle 3 rotates, an arm 35 thereon turns the star-wheel step by step until a pin 34 on the star swings the lever 36, against the action of a spring 38, into contact with a stop 31. The pin 34 then passes the lever 36, and, if the tone-arm is moving, friction between the parts 15, 37 assists the spring 38 to return the lever to the normal position shown, during the ensuing revolution of the star-wheel. If, however, the tone-arm has stopped when the pin 34 shifts the lever 36 in the manner described, the lever is prevented by the member 15 from moving back to the normal position, so that the next revolution of the star brings the pin 34 against a lug 40 on the lever. Further rotation of the star-wheel is thus stopped, and the pressure of the arm 35 on the star moves the bar 17 laterally, bringing the main part of the slot 22 into line with the screw 25. A spring 27 thereupon slides the bar outwardly and applies the brake to the turntable 5. In a modification the lever 36 is pivoted to the motor-board 2, instead of on the bar 17, and carries on a resilient member a pad engaging with a rigid convex member moving with the tone-arm. A further modification comprises, instead of the lever 36, a bell-crank, one arm of which is formed as an anchor coacting with two pins on the star-wheel, the other arm resiliently supporting a friction-pad engaging with a curved member moving with the tone-arm.

Title: Improvements in or relating to sheet classifier
IPC: B65H29/58
Filed: 1955-08-29
Abstract: 801,251. Endless conveyers for sheet material. WEAN ENGINEERING CO., Inc. Aug. 29, 1955 (Feb. 9, 1955], No. 24710/55. Class 78 (1). [Also in Groups XVI, XIX and XL (b). Defects on sheet metal are recorded so that when after being cut into separate lengths the sheets reach a sorting position they are sorted according to whether or not a defect is registered. As shown (Fig. 1) the strip 1 under test passes a thickness gauge 2 and pinhole detector 3. The gauge and detector are connected to a magneto recording head 17 so that if the sheet is defective in either respect a signal is recorded on a magnet tape 14 driven at a speed proportional to that of the strip. The strip then passes to a flying shear 5 where it is cut into individual sheets. As the defect passes the shear a pick-up 18 detects the defect recorded on tape 18 and operates a relay which prepares a circuit so that subsequent closure of a switch 32 operated by the shear transfers the signal to a second recording head 28 which records it on a second magneto strip 27. The movement of this second strip is synchronized with conveyer 7 and recorded defects are detected by a detector 29 which operates through a solenoid a deflector 10 so that defective sheets leaving the conveyer pass to a pile 13. Whole sheets pass to a third conveyer 11 and are piled at 12. In a modification, Fig. 3, separate magnetic tracks are used by the thickness gauge and pinhole detector. Thus the thickness gauge controls a first deflector and the pinhole detector a second one while prime sheets pass to a final piler. In Fig. 4 is shown an arrangement in which defective sheets pass from conveyer 82 to conveyer 84 while a magnetic roll 85 leads prime sheets over deflector 83 to a third conveyer 87.

Abstract: 1,128,488. Automatic exchange systems. INTERNATIONAL STANDARD ELECTRIC CORP. 3 June, 1966 [4 June, 1965], No. 24788/66. Heading H4K. In an exchange system having a multi-stage read-relay switching network and a common control circuit, the latter includes a memory in which the busy/idle state of each link is recorded on an individual core. The memory is provided with additional cores and the logic circuitry is such, that, during route searching, if all the links from one stage accessible to a just-selected link from the previous stage are busy, the next possible free link from the previous stage is selected and the links accessible thereto are then tested. The procedure is repeated until an outlet of the network is reached. The addresses of cores corresponding to links in a succeeding stage are stored with the free/busy data of links in a preceding stage in the manner described in Specifications 1,128,487, 1,128,489 and 1,128,490. Alternatively the addresses of cores in the next stage may be derived from a "translator" as described in Specification 1,126,075.

Abstract: 584,104. Electric resistances. STONE & CO., Ltd., J:, and AUSTIN, C. V. Dec. 11, 1944, Nos. 24843/44 and 4987/45. [Class 37] [Also in Group XXXV] In a carbon pile type regulator, the pile or the regulator comprising a pile is enclosed in an inert gas, such as nitrogen, hydrogen or carbon dioxide. In one arrangement, Figs. 1 and 2, two cylindrical metal bellows chambers 5, 9 are mounted on either side of a mounting plate 1 to contain a pile element 3. A bridle device 6 extends within chamber 5 from one face of the plate to form a fixed abutment 7 for engagement by one end of the pile 3, which end is provided with collector disc 8. The closed end of chamber 9 is adapted to transmit pressure to a collector disc 10 at the other end of the pile and an insulated rod 11 passing freely through the pile is rigidly and gas-tightly held by plates 12 to the closed ends of 5 and 9 so that pressure exerted upon end 10 of the pile compresses chamber 9 which effects corresponding expansion of chamber 5. In a modification, a cage 4, preferably of spaced rods having their ends fixed to the closed ends of the chambers, may replace rod 11. The pile is attached to bracket 13 of a regulator as shown in Fig. 1. The air within the chambers may be rendered inert after sealing, by electrical ignition of a small magnesium charge or by exhaustion of the oxygen in the said air during operation of the pile. In a further arrangement, Figs. 3, 4 and 5, the regulator is enclosed in compartments 26, 27 secured on either sid of a plate 28 and filled with inert gas which is introduced through non-return valve 53 in the spigot 52. Pressure is applied by a strut 38 to the movable collector 10 of the pile 3 which is suspended at this end in a plate 47 of frameshaped springs 40, 41 connected' by links 46 and supported by arms 42 of a bracket 43, carried by insulated base part 44 which is secured to flange 45 on casing 26. Connections to 8 and 10 are effected through gas-tight bushings 48. The pile may be adjusted for wear, etc. by means of screw device 51 enclosed by cover 31. Adjustment, without removal of cover 31, may be effected by rod 55 supported in diaphragm 56 attached to the cover and secured by nuts 57 on either side of bracket 58. Pressure compensating effect may be obtained by the use of two diaphragms. Casing 26 is provided with heat dissipating means such as fins 50. Specifications 555,269; 558,621 and 572,932, [both in Group XXXV], are referred to.

Abstract: 718,195. Changing waveshape. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 27, 1952 [Oct. 24, 1951], No. 24868/51. Class :38(2) In a pulse generating circuit of the kind forming the. subject of Specification 715,826 in which voltage pulses are produced upon saturation of a condenser D 1  having a non-linear dielectric fed from an A.C. source V 6  through a series resonant combination of inductor L, and capacitor C, duration of the pulses supplied to load R is reduced by adding a number of stages each comprising a series connected inductor L2, L3...Ln and a parallel connected saturable capacitor D2, D3...Dn. The capacitors are so chosen that the unsaturated value of capacity of the one of each stage is much less than and much greater than the unsaturated and saturated values of the one of the stage nearer the A.C. source respectively, while L1=L2=L3...= L . The time taken to charge and discharge the capacitor of each stage is smaller than the times associated with the preceding stage, so that the pulse length decreases as the number of stages increases. The output pulses may be made unidirectional by polarizing the saturable capacitors in the manner which forms the subject of Specification 718,191.

Title: Improvements in and relating to dough shaping equipment
Filed: 1959-07-22
Abstract: 877,193. Rolling dough. WADLEY, L. A. July 22, 1959 [July 23, 1958], No. 25185/59. Class 87(2). Dough lumps are rolled into balls in a machine having a conveying surface for the dough, a second surface in contact with the dough during the movement of the dough along its path and means to move one of the surfaces so as to oscillate the dough sinusoidally about its direction of travel. The dough is fed to the machine at 37, is centred by the action of wing zones 38 which are depressed as shown, and is passed through the machine between moving belts 5, 7 driven by rollers 8, 9. The lower, faster-moving belt 5 is located over a foundation 36 which imparts to it a convex surface and the upper belt 5 is similarly given a concave surface by a foundation 41. The foundation 41 and the driving rollers 9 for the upper belt are carried on pivot arms 21 which are moved so as to oscillate the upper belt across the width of the lower belt. A motor 22, also mounted on the structure of the pivot arms 21, drives a pulley 25, through a speed-reducing train of belts, which also acts as a crank disc for connecting rods 27 which are pivoted to the machine frame at 30, the arms 21 being pivoted at 31. The effect is a combined movement of the two belts which acts on the dough so that it appears at the output end 39 as a lump of  spherical shape. To adjust the spacing between the belts the pivot shafts 30, 31 may be raised and lowered together along guide zones 32. A belt tensioning arrangement is shown at 19.
