Filed: 1972-10-12
Abstract: 1413678 Treating polyester fibres EASTMAN KODAK CO 12 Oct 1972 [13 Oct 1971] 47189/72 Heading B5B [Also in Division G2] A method of imparting curvature to a film of a polyester or polycarbonate which is to be used as a photographic support comprises applying to one surface of the film a solution of a volatile phenolic compound in a solvent having a volatilization point below that of the phenolic compound and subsequently heating the film to a temperature above its 2nd order transition temperature to volatilize and completely remove the solvent and the phenolic compound. Volatile phenolic compounds are those easily removed by heating at a temperature above the 2nd order transition temperature of the polymer of which the film is made and are preferably phenol, resorcinol, pyrogallol, 4-phenyl resorcinol and 4-hexyl-resorcinol which may be applied in solutions containing 0À05-2 parts by weight of a surface-active agent and 15 to 20 parts by weight of the treating agent. The curvature imparted to the film is preferably such as to completely counteract the curvature produced when the untreated surface of the film is subsequently coated with a gelatino-silver halide photographic emulsion so that the resultant photographic film is completely flat. Examples relate to the treatment of polyethylene terephthalate films with (1) an aqueous solution of resorcinol, (2) a methylisobutylketone solution of resocinol and (3) a dichloromethane solution of phenol, the treated films being dried by heating at 130 C. and subsequently coated with a silver halide photographic emulsion.

Filed: 1966-10-24
Abstract: 1,091,319. Sewing machines. UNION SPECIAL MACHINE CO. Oct. 24, 1966 [Oct. 26, 1965], No. 47555/66. Heading DIG. [Also in Division F2] The rate of work feed in a sewing machine is regulated by the eccentricity of a crank pin carried adjustably by a driving shaft, the pin and shaft having interconnected lubricant passageways. The bed shaft 108 is formed with an axial bore 136 and is journalled in a bearing 268 mounted in a transverse wall 266 bounding an oiltight chamber filled during operation with oil mist. Bearing 268 is formed with a first helical groove which forces oil collected from said chamber through an inlet port 274 into bore 136, and with a second reverse-handed helical groove which forces back into port 274 any oil passing the latter. One end of bore 136 is closed by a screw 276, and the other end communicates with a bore 138 in an extension of a block 102 rigid with the end of shaft 108. Block 102 is formed with a transverse groove 103 and supports a plate 104 formed with a transverse slot 176 communicating with groove 103. A block 10, slidable in groove 103, carries on one side a crank pin 14 which passes through slot 176, and is formed on its other side with a recess 46. Crank pin 14 is formed with an axial bore 60 which communicates with recess 46 and has a lateral port 58. Recess 46 houses a plate 130 formed with two apertures 132, one of which communicates with bore 138, and which are joined by a groove 134. Plate 130 is surrounded by an oil-tight gasket 126. Bore 138 contains an oil filter pad 139. Block 10 receives a screw 62 formed with a head 123 engaging the upper edge of plate 104, and with a collar 122 engaging the upper edge of slot 176. Rotation of screw 62 thereby shifts crank pin 14 from a position of minimum eccentricity when a surface 36 of block 10 engages collar 122, to a position of maximum eccentricity when the lower surface of block 10 engages the lower edge of slot 176. Surface 36 co-operates with a scale at the edge of slot 176 to indicate the extent of eccentricity. Crank pin 14 supports a sleeve 110 secured non-rotatably thereto by the head of a screw 124 and having an aperture 146 aligned with port 58 to supply oil to a needle bearing 112 in an arm 114 connected by a link 240 to a feed-advance shaft 226 actuating a feed bar 224. Excess oil from bearing 112 falls on to a sloping felt-covered' surface 282, and is delivered therefrom by a wick 284 to a tube 286 which passes through a wall 292 bounding the oil-tight chamiber, and which is connected by a further tube 296 to a pump (298) actuated by shaft 108.
