Patent GB-805376-A (GB)
Title: Adhesives
IPC: C09J4/06
Filed: 1956-05-22
Abstract: An adhesive comprises a solution of natural rubber in a strong solvent therefor, a butadienestyrene copolymer and a polymerizable monomer such as styrene which is a solvent for the copolymer. Preferably the strong solvent is an aromatic or a chlorinated aliphatic hydrocarbon and constitutes at least 50 per cent of the combined weight of strong solvent and polymerizable monomer.  The weight of copolymer may be 5 to 100 per cent of the weight of natural rubber.  The adhesive may also contain 10 to 100 per cent by weight of the natural rubber of cyclized or chlorinated rubber or other rubber resin compatible with natural rubber.  The natural rubber solution may be prepared by treating the rubber with the strong solvent until it has swelled to a spreadable consistency.  In an example, 2.5 kg. of natural rubber are swelled in 46 kg. of trichloroethylene for 8 to 14 days and the resulting solution is added together with 1.25 kg. of natural rubber and 0.75 kg. of cyclized rubber to 0.75 kg. of a butadiene-styrene copolymer dissolved in 5.5 kg. of styrene.  The adhesive is especially useful for adhering a vulcanized or unvulcanized natural rubber surface to another surface in shoe manufacture.  A layer of the adhesive is applied between the surfaces to be bonded together and the strong solvent allowed to evaporate, one or both of the surfaces being heated to 60 DEG  to 100 DEG  C. immediately before the surfaces are assembled together.

Abstract: 899,429. Copying telegraphy. FAIRCHILD CAMERA & INSTRUMENT CORPORATION. May 11, 1959 [May 20, 1958], No. 16029/59. Class 40(3). In an apparatus for the electrical reproduction of an image of an original by synchronously rotated transmitting and receiving drums in association with axially moved scanning and reproducing heads having their axial movement effected by means operated in timed relation with the rotation of the drums, the scanning head is secured to the member producing the axial movement by an engaging device which is rendered operative by members rotating with the transmitting drum during a portion of each cycle of its rotation so that effectively an enlarged reproduction of the original is made. Reproducing and transmitting drums 10, 12 mounted on a shaft 18 rotated by a motor 46 also driving a pulley 36 which in conjunction with a pulley 40 moves a steel belt 38 to which the reproducing head 30 is permanently secured and to which the scanning head 32 is attached by an upper clamp 42 or a lower clamp 62, the latter being employed when a mirror image of the original is desired. The upper clamping is effected by the energization of the solenoid 64 which by its core 66 and a resilient tongue holding the belt 38 against the upper arm 70 of a jaw member 42 on the scanning carriage 32. For the reverse movement, the energization of a solenoid 72 holds the belt 38 against the lower member 78 of a jaw 62. When a drum 12 of a different diameter is inserted for the mounting of the original to be reproduced, the scanning assembly 32 may be adjusted radially relative to the drum on rods 88 and held in its adjusted position by locking spindle 96. The period during which the solenoid 64 (or 72) is operative is determined by contact members 48, 50 operated by associated cams 54, 56 on the shaft of the drum 12. Circuit arrangements. The degree or extent of enlargement may be selected by appropriate operation of a switch 60, the 1/1 ratio operating solenoid 64 or 72 for direct or "mirror" reproduction dependant on the position of the switch 58, during the complete rotation of the transmitting drums 12. For the ratios 1.6, 2.2 the contact members 48, 50 are respectively operated by cams 54, 56. To provide for automatic operation in part, the axial adjustment of the scanning carriage 32 along the rods 88 to correspond to the diameter of the drum 12 used for mounting the original controls switch members 124 and 126 neither of which is operated for the 1/1 ratio, the switch 126 being in the operated position (shown) for the ratio 1.6 and both switches 124, 126 being in the operated positions for the 2.2 ratio. A modification for deriving a reduced reproduction is described in connection with Fig. 8 (not shown), in which the movement of the scanning carriage is normally faster than that of the reproducing carriage and the clamping means is utilized to lessen the reduction of the reproduction. Specification 692,349 is referred to.
