Title: Production of ingots having changes in cross-section along  theirlengths
IPC: B22D23/10
Filed: 1972-11-01
Abstract: 1447230 Electroslag refining ASSOCIATED ELECTRICAL INDUSTRIES Ltd 31 Oct 1973 [1 Nov 1972] 50401/72 Heading B3F Apparatus for producing, by an electroslag refining process, an ingot having a change in cross-section and/or a transverse dimension along its length comprises a succession of superimposed moulds 2, 4 and 10 open at both ends, the lowermost mould 2 being movable longitudinally away from the other moulds. In the embodiment shown, a base-plate 8, the mould 2 and a consumable electrode 14 are movable vertically by means of arms 9, 7 and 15 extending from carriages arranged to run up and down a mast. The moulds 4 and 10 are restrained against movement in a vertical direction but the mould 10 can be swung horizontally into and out of its casting position. At the start of the casting process the mould 10 is swung aside and the mould 2 is positioned with its upper end in abutment with the lower end of the mould 4. An ingot is then built up within the mould 2 by electroslag melting of the electrode 14. When the molten slag 16 and pool of molten metal 17 rise into the mould 4, the electrode 14 is replaced by one of larger diameter and the process continued with the mould 2 and base-plate 8 being lowered continuously to withdraw the ingot from the mould 4 as it is formed. When the portion 5 of the ingot reaches its desired length, the mould 10 is swung into position, an electrode of reduced diameter placed in the electrode holder 13, the molten slag and metal allowed to rise into the mould 10 and the process continued as before with the mould 2 being lowered until the ingot has obtained its desired length. In a modification, the mould 2 is shorter than the ingot portion 3, the latter being built up to its desired length by lowering the baseplate 8 relative to the mould 2 to withdraw the ingot from the mould as it is formed.

Abstract: 1333783 Thermographic processes and apparatus XEROX CORP 27 Oct 1970 [29 Oct 1969] 51013/70 Headings G2A and G2C A thermographic process comprises applying a coloured liquid to a non-porous support to form a continuous or discontinuous layer (if support is recessed), imagewise exposing to radiation of sufficiently high intensity (e.g. a flash) to cause the radiation to be converted to heat and to form vapour in the coloured ink which is propelled from the support in the exposed areas. As exemplified, a paper receptor sheet is used and placed 2-12 mils from the liquid and the assembly is imagewise exposed through the support to propel the liquid (with or against gravity) to the receptor sheet to produce a coloured image thereon. Exposure through the receptor sheet may occur if a transparent receptor sheet and a black support for the liquid layer is used. The support specified is a glass slide taped round the edge or grooved to contain the liquid or a grooved metal support or a gravure plate may be used. The specified liquid is carbon black particles dispersed in isopropyl alcohol. As shown, a revolving transparent glass or plastics drum 1 which is preferably grooved has coloured liquid 2 applied by roller 3. The liquid is exposed to laser 7 collimated by lens 9 through transparency 5 so that the liquid is propelled from the grooves across the gap to paper sheet 15 revolving on drum 17 to produce a negative image 21 thereon and leave a positive image 19 on drum 1.

Abstract: 1276910 Photo-electric device EASTMAN KODAK CO 28 Oct 1969 [28 Oct 1968] 52816/69 Heading G1A [Also in Divisions G4 and H4] A range finder has means for transmitting light mounted coaxially with optical means admitting light only through an annular or part-annular portion, reflected light passing therethrough being refracted to an image plane at which photosensitive means are disposed in configurations in which predetermined loci are functions of the range and also has means for identifying the locus delineated by the refracted light. A light source 38 is supplied from a single flash power supply, the light passing through a collimating lens 46, the whole arrangement being mounted at the centre of an apertured spherical lens 30. Light reflected from a subject passes through the portion 50 of the lens 30 that is not covered by a mask 48. The light is refracted and forms an annular image on the plate 52 mounted on the rear wall of the casing 28. On the plate 52 are mounted four annular Fig.3 (not shown) or semi-circular Fig.4 (not shown) selenium cells (54-60). These photosensitive cells are connected to amplifiers and Schmitt triggers which operate solenoids. The diameter of the annular image is inversely proportional to the range of the subject if the plate 52 is inside the focal length of the lens 30, thus the range is determined by which solenoid is actuated. In a camera the range finder solenoids operate stops e.g. pawls engaging teeth on the lens which limit rotation of the lens to provide automatic focusing Fig.6 (not shown). A pointer on the lens provides visual indication of the range. The range finder may be actuated by the shutter release, the lens then being rotated under the action of the spring until it engages the stop, at which point the shutter is released exposing the film. In a further embodiment Figs.5A-C (not shown) only one half of the lens is used and the photo-sensitive cells may be only part annular.

Abstract: 1276050 TR switches; waveguides WESTINGHOUSE ELECTRIC CORP 9 Nov 1970 [31 Dec 1969] 53196/70 Headings H1D and H1W A microwave TR switch for a radar system comprises a pair of electrodes 10, 11 extending from the broad walls 12, 13 of a section of rectangular waveguide 5 to define a discharge gap 19 in which there is disposed a capillary tube 26 containing an ionizable gas so as to lie within a static magnetic field produced by magnet 28, the field lines from which are parallel to the electric vector of the H 01  mode microwaves propagated in the waveguide. The capillary tube which may be of quartz or sapphire and contain for example Cl 2  or HCl at a pressure of 5-15 torr, extends across the discharge gap and is disposed within a bore passing through the upper electrode 10 and the upper leg 28a of the magnet where it terminates in a reservoir (not shown). Extending inwardly from the narrow walls of the waveguide are vanes 14, 16 which form a tuned iris. The iris constitutes the inductive portion of the tuned circuit and the two electrodes the capacitative portion. A high power E.M. wave, preferably the dominant TE 01  mode, produces a high inter-electrode voltage causing ionization of the gas and a current discharge within the capillary tube. The magnetic field is thought to cause the discharge electrons to move in helical paths thereby reducing electron loss at the wall of the capillary tube and extending the electron life-time such that when the radar is operated with a long inter-pulse period enough electrons remain after one pulse to facilitate the subsequent discharge breakdown.

The clockwise distance travelled by ring 3 (and hence the diaphragm opening) is determined by the position of an abutment pin 11 between actuating lever 10 and a drive lever 9 operated on clockwise release of a cocked drive cam 5 (from the position shown), pin 11 being connected via a link 12 to an adjusting lever 13 carrying a pin 13a which engages a cam surface 23 or 23a. The time of clockwise travel of ring 3 is determined by the retarding action of a lever 14 on a pin 10c carried by actuating lever 10, lever 14 being controlled by a variable governor mechanism comprising a lever 19 carrying an escapement member 17, gear 16 and pin 19 engaging a cam surface 24 or 24a. After projection 5b of drive cam 5 passes arm 9b of drive lever 9, blades 2 are closed by anti-clockwise rotation of ring 3 under the action of a spring 4 and finally by contact of projection 5b with a pin 3b on ring 3, the spring tension (and hence the time of closure) being determined by the position of a pin 20a on a cam surface 25 or 25a. The cam surfaces 23, 24 and 25 (operative in programme 1) and 23a, 24a and 25a (operative in programme 2) form part of adjustment ring 22.

Abstract: 1410388 Granulating from suspensions HOBEG HOCHTEMPERATURR REAKTOR-BRENNELEMENT GmbH 20 Nov 1972 [18 Nov 1971] 53583/72 Heading B5A [Also in Division C1] Spherical particles containing solid material, especially a neutron absorbing or a moderating material, e.g. graphite, carbon black, boron, boron oxide, boron carbide, silicon or silicon carbide, are produced by suspending particles of the material in a solution comprising a solvent containing one or more organic compounds capable of curing to yield a solid product; dripping or spraying drops of the suspension into a body of liquid immiscible to the solvent, and allowing the drops to fall through the liquid whilst the organic compounds are cured so that the drops solidify. The organic compounds may be a phenol, e.g. resorcinol, or urea and an aldhyde, e.g. formaldehyde, the solvent being water and the immiscible liquid being paraffin oil. Alternative liquids are organic solvents and dissolved amines or ammonia may be present. The suspension may include an acid catalyst such as an organic carboxylic or sulphonic acid, several examples being given. After curing the particles may be washed, dried, heated to, say 600‹ C. to carbonize the resin which may then be graphitized, e.g. at 1800‹ to 2600‹ C. This process gives boron carbide particles coated by a gastight pyrocarbon-containing layer. Apparatus comprises containers of suspension 1 and curing agent 2 connected to a jet vessel 5 via proportioning pumps 3 and 4. The contents of vessel 5 are stirred by agitator 7 and forced through jets 8 into a receiving vessel 9 filled with paraffin oil which is heated by a jacket 12. The solidified descending particles are collected in vessel 11 and drawn off intermittently through outlet 32. Liquid levels and temperatures are maintained by means of a system of separator and storage tanks 18, 19, 20, 28, 31 and 15 together with heaters 21, 29, pumps and valves. Examples of suspensions are: (1) Boron carbide containing carbon composed from water 1000 g., resorcinol 375 g., mellitic acid 5 g., cyclohexane sulphammic acid 40 g., amorphous boron 45 g. and 400 ml. of 40% formaldehyde curing agent; (2) Carbon particles composed from water 1000 g., resorcinol 410 g., canesugar 25 g., pyromellitic acid 5 g., toluene sulphonic acid 35 g., soot or graphite powder 40 g. and 425 ml. of 40% formaldehyde as curing agent.

Preferably the struts are #" diameter high density polyethylene of sufficient rigidity not to buckle when a force is applied axially in one direction and counteracted by tension in longitudinal members 2. The members 2 comprise filaments or twines of synthetic plastics material. Both struts 2 and members 1 may include electrically conducting wire filaments. The longitudinal members may be joined to the struts by injecting heated plastics into moulds placed about their intersections. Alternatively the struts are formed by moulding whilst the preformed longitudinal members are in place. A fence is obtained by tensioning the mesh between posts 3. The relative rigidity of the struts ensures that the effective height of the fence is not decreased by a rise in the terrain as at 5. The fence may be electrified.
