Patent GB-475906-A (GB)
Title: Process for the production of novel discharge effects on cellulosic fabrics
IPC: D06Q1/02
Filed: 1936-05-29
Abstract: Pattern effects on fabrics of cellulosic material such as cotton, or regenerated cellulose, are obtained by printing the fabric with strong caustic alkali lye and a thickening agent, subjecting the printed material to the action of an a b  - alkylene oxide or derivative thereof, and then treating the material with aqueous caustic alkali solution so as to remove from the printed portion material that has been rendered soluble in p  aqueous caustic alkali solution.  Ethylene oxide, propylene oxide, or glycide, may be used as etherifying-agent.  In the case of lighter cloths the solubilizing treatment with caustic alkali may be effected by immersing the treated material in water or even in dilute sulphuric or other acid. In this case, the caustic alkali in the printing paste diffuses out and removes the soluble cellulosic substance before neutralization by the dilute acid has had time to be effected.  In an example, cotton velveteen is printed with a paste of brown British gum, caustic soda, and water.  The undried fabric is suspended in a closed chamber and subjected to ethylene oxide vapour.  It is immersed in cold dilute caustic soda until the pile of the printed portion is dissolved, then washed, and dried.  An etched pattern is formed.  In another example, cotton velveteen is similarly treated with propylene oxide vapour, after being printed with caustic soda paste, the temperature during the vapour treatment being maintained at 50 DEG  C. by means of heating coils.  In other examples, plain cloth and cotton velveteen are printed with caustic soda paste and then subjected to the action of ethylene oxide dissolved in carbon tetrachloride or glycide dissolved in acetone.  The materials are hydro - extracted and then treated with dilute caustic soda solution.  In the case of the plain cloth, a fabric resembling lace is obtained.  Specification 231,804, [Class 2 (ii)], is referred to.

Filed: 1968-03-29
Abstract: 1,246,481. Cutting glass. PILKINGTON BROS. Ltd., F. J. GROVE, D. C. WRIGHT, and F. M. HAMER. 21 March, 1969 [29 March, 1968], No. 15301/68. Heading C1M. Glass is cut along a desired line by effecting relative movement between the glass and a laser beam impinging thereon, which laser beam is of a wavelength to which the glass is' opaque, the energy density of the beam being regulated so that a stress field is set up in the glass along the line in question, and the glass is separated by a fracture which runs from a point of weakness along said line. The process may be applied to cutting or trimming sheet glass produced by the float or vertical draw processes. The laser may be traversed from a weakened point, e.g. a score in the edge of the sheet, so as to start the desired fracture, or the beam may travel towards the score so that the fracture runs back from the score along the line of energy application. Alternatively the score may be made after traversing the sheet with the laser. The glass may be subjected to mechanical stress after application of the beam, since the glass is not necessarily fractured immediately on applying the beam. The invention may also be applied to cutting other glass objects, e.g. tubes. In the embodiment illustrated a glass sheet 2 has impinging thereon a laser beam 10 produced by the laser 7, the beam being reflected on to the sheet by mirror 16 which is so mounted as to allow the beam to traverse the glass. The mirror may be of glass plated with gold on its front face. For cutting commercial glasses a laser with an output wavelength of 2À5-500 Á is used.

Title: Improvements relating to the production of filament and film-forming polyethylene terephthalates
Inventor: BILLICA HARRY ROBERT
IPC: C08G63/86
Filed: 1953-06-05
Abstract: A continuous process for making filament- and film-forming polyethylene terephthalate comprises continuously injecting into a polymerization system bis-2-hydroxyethyl terephthalate with antimony trioxide as a polymerization catalyst, and continuously withdrawing polyethylene terephthalate from the polymerization system.  A very large number of uses are specified for the polyethylene terephthalate produced.  In an example, bis-2-hydroxyethyl terephthalate was first prepared continuously by feeding dimethyl terephthalate, ethylene glycol, lithium hydride and zinc acetate dissolved in ethylene glycol, and a paste of antimony oxide with ethylene glycol to the top-plate of an ester-interchange column.  The product withdrawn from the bottom of the ester-interchange column was then continuously prepolymerized to intrinsic viscosity 0.25 by passing it upwardly through an inverted bubble cap column maintained at a pressure of 10 mm. of Hg. and a temperature of 255 DEG  C. at the bottom and a pressure of 3.5 mm. of Hg. and temperature of 270 DEG  C. at the top. The prepolymer was then continuously polymerized to intrinsic viscosity 0.62 by passing it through a horizontal cylindrical vessel heated to 280-285 DEG  C. and housing revolving intermeshing discs which serve to move the polymer through the tube and to provide exposure of a large surface area of the reaction mass to the effects of a vacuum maintained at 3.5 mm. of Hg.
