Title: Automatically positioning radiation beams
Inventor: UNDERHILL MICHAEL JAMES
IPC: H01J37/304
Filed: 1969-05-09
Abstract: 1,211,529. Template followers; programme control. MULLARD Ltd. May 9, 1969, No.23762/69. Heading G3N. An apparatus for positioning the area of incidence of a beam of radiation on a target provided with a fiducial mark comprises a step-wise beam deflecting means, a Schmitt trigger changing over when a step crosses on edge of a mark and means for providing an output signal indicating within which step the edge is crossed. As shown, an on-line computer 14 moves an electron beam in a series of steps across a target 3 in the X direction by controlling the energization of a deflection coil 4 through a digital-to-analogue converter 17 and amplifier 19. When the beam crosses a mask, not shown, a pulse is developed which, through a capacitor and an amplifier 7 triggers a Schmitt circuit 8, coupled through a capacitor, to multivibrators 9, 10 operating in opposite senses, to cause an 'interrupt' of the computer on line 12, 13. The computer then issues a 'cancel' on line 21 to the multivibrators. It is stated that the computer can be programmed to issue large steps until an 'interrupt' is signalled on line 12 and the beam movement is then reversed in small steps until an 'interrupt' on line 13.  After positioning in the X direction the positioning is repeated for the Y direction. The mark may alternatively be detected by secondary emission. The electron beam machine is used to cut out selected portions of the target 3 or expose selected areas of a'photo-resist provided on the target.

Title: Improvements in or relating to the treatment of materials made of, or containing, organic derivatives of cellulose
IPC: B29D30/20
Filed: 1930-08-08
Abstract: Effects are produced on materials made of or containing organic derivatives of cellulose by applying to them a composition containing an effect material and a water-insoluble thickening agent in a medium containing an agent having no appreciable solvent effect on the organic derivative of cellulose present in the material, but which exercises a solvent action on the thickening agent, and a small proportion of a substance which possesses a solvent action for the organic derivative of cellulose present in the material.  The material to be treated may contain cellulose esters, e.g. acetate, formate, propionate or butyrate, or cellulose ethers, e.g. ethyl, methyl or benzyl cellulose, alone or in admixture with other fibres such as silk, cotton, wool or reconstituted cellulose.  The effect materials include pigments and mineral effect materials, e.g. barium sulphate, zinc oxide, metal powders, with or without dyes, particularly such as have affinity for the organic derivative of cellulose present in the material.  The thickeners may be cellulose derivatives, such as cellulose nitrate or a cellulose ether.  If cellulose nitrate is employed as thickening agent for producing effects on a fabric containing cellulose acetate, the medium employed may consist of alcohol and ether, while if cellulose ethers are employed as thickening agents for treating materials containing cellulose acetate or other cellulose derivatives insoluble in benzene or toluene, one of the latter may be employed as the medium.  The substance having a solvent action on the cellulose derivative present in the material may comprise 10 per cent of the liquid constituents of the composition.  For materials containing cellulose acetate, the solvent may be acetone, methylethyl ketone, a sulphocyanide, ethyl acetate or trichlorethylene.  The effect compositions may also contain plasticizers, e.g. camphor, triphenyl phosphate, tricresyl phosphate, tributyl tartrate, diethyl phthalate, triacetin or xylene monomethyl sulphonamide. The composition may be applied by the methods described in the parent Specifications, for example, locally by printing or spraying through stencils or, to the whole surface of the material, by immersion in a bath containing the composition.  The material may be subjected to any desired treatment, e.g. dyeing or delustring, before or after the application of the effect composition.  In an example of a composition for treating a fabric consisting of cellulose acetate, a dry dyestuff, e.g. 1-amino-4-oxyanthraquinone, is ground and incorporated in a solution containing nitrocellulose, camphor, xylene monomethyl sulphonamide, acetone or methylethylketone, methylated spirit and propyl or butyl acetate.

Title: A neutron flux dosimeter
IPC: G01T3/00
Filed: 1959-07-10
Abstract: 919,192. Detecting neutrons. COMPAGNIE DE SAINT-GOBAIN. July 10, 1959 [Sept. 5, 1958], No. 23862/59. Class 39 (4). [Also in Group XXIII] A neutron dosage meter comprises a body of heterogeneous glass having two or more juxtaposed zones, one of the zones reacting to neutron irradiation in a different manner from the others, the body deforming when irradiated by neutrons, to a degree which is a function of the dose received. In one example two rods of glass, one of which is rich in boron, each has one of its ends softened by heat; the softened ends are brought into contact with each other and the rods drawn away from the softened ends to form a glass wire. After cooling, the wire has a certain curvature due to differential contraction, and on exposure to neutrons the curvature alters as a function of neutron dose. In another example a plate of glass rich in boron is treated on one face with sulphuric acid to eliminate the boron for half the thickness of the plate. The plate curves on exposure to neutrons, the curvature being a function of neutron dose. The dosage meters may be introduced into a nuclear reactor and can be made to operate an electric switch when a predetermined dose has been absorbed; an electric heating device may be provided to restore the dosage meter to its original condition.

A method of machining a workpiece 13 by electric spark discharges comprises a tool electrode 14 of wire or strip form supported in tension and extended formation in the sparking zone 23 and fed therethrough from a bulk supply so that each part of the wire or strip is used once only during the whole of the feed movement. The wire electrode 14, preferably of brass, is supported on either side of the sparking zone by wire-drawing dies 24, 25 and fed through the zone 23 from a storage reel (not shown) to a receiving reel (not shown) by means of a motor 20 driving through reduction gearing 21 a tapered sleeve 22 on which the wire is lapped. The die 24, in the approach path of the wire, has an aperture of less area than the crosssection of the wire and the die 25 has an aperture equal to or smaller in size than that of the die 24. The wire may be fed continuously or intermittently, the speed of feed or the period of dwell respectively being such that no significant erosion of the wire occurs. The workpiece 13 is carried by a member 12 which may be mounted on the machine frame 10 so as to be adjustable transverse to the wire electrode in the horizontal and/or vertical directions and also, if desired, angularly about an axis perpendicular to the electrode. Such adjustments may be controlled manually or automatically by motors controlled by the spark discharge voltage. The workpiece, electrode, and dies are immersed in a cooling liquid 17, such as paraffin oil supplied to and drained from a receptacle 16 by pipes 18 and 19 respectively. The positive and negative contacts of the spark producing circuits are connected respectively to the workpiece and the die 24. The invention is particularly applicable to forming holes in tungsten carbide or other hard materials or to forming wire-drawing dies, the electrode wire passing through a pilot pole in the workpiece which is traversed normal to the electrode or angularly adjusted with respect thereto to produce the required shape of the hole.
