Title: Development of Light-Sensitive Layers
Inventor: LAWSON LESLIE EDWARD
IPC: B41N3/08
Filed: 1966-05-31
Abstract: 1,188,527. Developing photo-sensitive materials. ALGRAPHY Ltd. May 8, 1967 [May 31, 1966] , No. 24263/66. Headings G2C and G2M. Positive-working, photo-sensitive materials are imagewise exposed and developed by a developer containing or consisting of a non-aqueous, non- alkaline phase containing ethyl alcohol or a waterimmiscible organic solvent which selectively dissolves the exposed areas to produce a positive image. The developing solution may also contain a dye, a resin or an emulsifying agent. In the examples, a diazonium salt or a napthoquinone diazide sulphonic acid ester and a novolak, a diazo resin p toluene sulphonate, or a naphthoquinone diazide sulphonic acid ester of a novolak is coated on a support (e.g. chromium on brass, copper foil/ resin laminate), exposed to a positive image and developed with a solution of 2-ethyl-hexanol, 1- octanol, 2, 6-di-methyl-4-heptanone, 6-methyl- 3-heptanone, diethyl phthalate, n-hexyl acetate, diethyl carbonate, 3-methyl-2-pentanone or industrial ethyl alcohol to produce a positive image. The image may be etched (if a metal support is used) and lacquered in the image areas with a solution of an epoxy or vinyl resin and a dye in an organic solvent and the material given a fogging exposure. The material may be heated to 100 C. after coating and before exposure. An alternative method is to imagewise expose the material using a copper foil/resin laminate support to a negative, develop as above, electroplate with silver, remove the remaining resist and etch the bared copper areas.

Title: Improvements in or relating to the marking of articles to be laundered, dry-cleaned,dyed or the like and means therefor
IPC: D06F93/00
Filed: 1936-09-05
Abstract: Textile or other articles to be laundered, dry-cleaned, dyed or similarly treated are marked by applying an ink containing an organic solvent to a local area of the article, which area has been made different from the remaining area by the application thereto of a water-insoluble material capable of penetration or swelling by the organic solvent.  Such water-insoluble material may be, for example, a cellulose ester or ether or a synthetic resin and the use of cellulose acetate or acetobutyrate is specified.  A film of such material may be produced in the area by chemical means or may be applied as a solution or suspension thereof which is then evaporated, or by cold or hot pressing in presence of a solvent for the film material or the fabric, or, e.g. in the case of a thermoplastic material or of a material dissolved in a fusible solvent, may be applied by hot ironing; alternatively, a tape impregnated or coated with the material may be attached to the article by sewing or by metal staples.  In an example, a label, obtained by cutting up a compound fabric made by moistening a cotton fabric with a solution of cellulose acetobutyrate in acetone and applying a thin film of cellulose acetobutyrate thereto by hot ironing, is attached to the article and is marked with an ink consisting of a suspension of ultramarine in an acetone solution of cellulose acetate.

Title: Improvements in or relating to the working of metals
Inventor: COX ALAN JOHN
IPC: B24B39/04
Filed: 1961-07-12
Abstract: 957,805. Making crank-shafts; rolling. BIRMINGHAM SMALL ARMS CO. Ltd. Oct. 11, 1962 [July 12, 1961], No. 25178/61. Headings B3A and B3M. A method of rolling the fillets of the crankpins and journals of a crank-shaft comprises rolling all the fillets except those of one or two journals, measuring the amplitude of eccentricity of the or each remaining journal, and then rolling the or each remaining journal to cause opposite distortion of the crank-shaft to reduce the eccentricity to an acceptable value. Rolling of the fillets leads to burnishing, which improves the physical properties and fatigue resistance of the fillets. Control of the rolling may be hydraulic pneumatic or electric. As shown, clamps 6 carrying hydraulically actuated rollers are arranged on the crank-pins and journals of the crank-shaft 1, cylinders 7 determining the pressure on the rollers. The crank-shaft is driven through gearing 4 by a motor 5, and an indexing drum D driven by the same motor through gearing G actuates valves 8-11 to control the rolling sequence. These valves direct fluid at either high or low pressure from reducing valves VH and VL to the cylinders 7. For rolling the final journal, signals from a transducer 26 and a reference pick up 27 are fed to a computer 28 to control, via a valve 29, the rolling pressure in a cylinder 34. The cylinder 34, Figs. 3 and 4, controls the pressure between rolls 39 and inclined rolls 38 through levers 31 and 32, the rolls 38 being supported by a profiled back-up roll 37. Specifications 943,255, 957,711 and 957,712 are referred to.

Filed: 1927-09-26
Abstract: 287,408. Marks, E. C. R., (Nash Fngineering Co.). Sept. 26, 1927, Pumping-machines; starting, facilitating.-A centrifugal water pump is primed by means of an air pump which is rendered ineffective when the head of water on the centrifugal pump rises to a predetermined point and is rendered effective again when the water head fails. The suction pipe 13 of the centrifugal pump 12 enters the lower part of the separating tank 10 which obtains its water supply through the inlet pipe 11. The priming air pump 20 is connected by pipes 21, 23 to the casing of the pump 12 and by a pipe 22 to the top of the tank. A chamber 30, connected between the pipe 23 and the tank, contains a float 32 which operates an air admission valve 31. Check valves 38, 25 are placed in the pipes 21, 23. The air pump 20 draws air from the centrifugal pump 12 at starting and also draws air from the tank 10 thereby causing the water level to rise in the tank. When this reaches the level X, X, the float 32 is lifted to open the valve 31 to admit air to the system so that the air pump is limited in its operation. When the level drops, the valve 31 is closed and the action of the air pump again becomes effective.
