Title: Improvements in or relating to the Exposure of Photographic Plates Suitable for Use in the Manufacture of Thin Film Circuits
Inventor: MADDISON JOHN CLARK
IPC: H01L49/02
Filed: 1966-04-07
Abstract: 1,187,206. Photographic printing processes and apparatus therefor. PLESSEY CO. Ltd. May 10, 1967 April 7, 1966], No.15585/66. Heading G2A. Patterns are produced on photographic films by progressively exposing the film to a light spot whilst producing controlled relative movement between the film and spot and utilizing a filter or a shutter to expose the film to the spot before and after such movement so that the pattern is uniformly exposed at both ends thereof. Apparatus for this method comprises a table for supporting the film, an arrangement for projecting a rectangular light spot on film, means for producing relative movement of the table and spot along co-ordinate axes and either a filter or a shutter for producing uniform exposure of the film at the start and finish of the movement. As shown, a photographic film (not shown) is placed on table 1 which can be moved in the X and Y plates by drive mechanisms 4 and 5. Above the film is a lens shutter assembly 8 and bellows 7. Light from lamp 13 passes through locating holes 9 and cut out 10 in opaque screen 12 and is focused on the film by opening shutter 16. The square hole 11 is then focused on the film and exposed by a tungsten iodide lamp 14, the size of the hole being adjustable preferably by using a second opaque screen with square holes of varying size. The exposure is adjusted by progressively opening the shutter in the direction of movement of the film so that on subsequent moving the film the film is not doubly exposed. Similarly, after the end of movement of the film, the shutter is progressively closed in the direction of movement of the film. Alternatively, uniform exposure is achieved by covering the square hole with a graded filter which passes all light at the rear end of the film before movement and reversing the filter after movement of the film. The position of the table can be determined by generating electrical impulses when drive mechanisms 4 and 5 are moved or alternatively electrical impulses may be used to drive the mechanisms 4 and 5.

Title: Improvements in or relating to a process for crimping filaments
Inventor: LEWIS HANSFORD JOHN
IPC: D02G1/10
Filed: 1957-05-17
Abstract: <FORM:0839393/IV (a)/1> A filament of a synthetic linear condensation polymer is drawn as it is "edge-crimped" by passage, under tension, over and in contact with a taut wire or a filament, e.g. another run (on the path A, B, C, D, B, E) of the filament to be crimped, travelling across the path of the filament to be crimped so that the latter filament is bent over the travelling wire &c. through an angle (at least 170 degrees) thereby becoming potentially crimpable, i.e. capable of developing crimp when relaxed by release of controlling tension.  The filament(s) to be crimped may be monofilament, twisted or nontwisted multifilament(s).  The temperature may be raised, e.g. by passage over a hot convex plate or around a hot roller, to 15 DEG C. below the melting point of the polymer.  Crimp development may be assisted by heating and/or swelling agents applied before or after knitting or weaving into fabric.  Crimped filaments may be subjected to dry or moist heat-setting treatment. Specifications 558,297, 722,756 and 761,084 are referred to.

Abstract: 1409834 Separating hydrocarbons DEUTSCHE TEXACO AG 4 April 1973 [27 April 1972] 16048/73 Heading C5E n-Paraffins are produced from mineral oil distillates by reacting the oil, diluted with an organic solvent, with urea to form a pulverulent adduct of average particle size below 0À1 mm., washing the adduct with the solvent, treating the washed adduct with fresh solvent at a temperature between the adduct forming and adductdecomposition temperatures, cooling the mixture of adduct and fresh solvent to the adduct forming temperature, separating the adduct from the cooled mixture and recovering nparaffin product by decomposing the adduct. Distillates, such as light gas oil boiling from 210-315 C. or spindle oil boiling from 317- 420 C., are treated with solid urea or with aqueous urea solution saturated at 70 C., to produce adduct at 20-40 C. Suitable organic solvents with which the oil is diluted consist of pentane, hexane or benzene together with 5-35 volume per cent of a ketone (e.g. methyl isobutyl ketone). The washed adduct can be treated with the fresh solvent at 40-60 C. by stirring with liquid solvent or by contacting with solvent vapour, at least part of which is condensed and then cooled (e.g. by incorporating liquid butane and evaporating the butane) to the adduct forming temperature; the adduct is then separated and decomposed, e.g. at 85 C. with the addition of water. The steps of separating the first formed adduct from the oil, washing the adduct and treating the washed adduct can be carried out in a centrifuge.
