Title: Continuous writing framing camera
IPC: G03B39/04
Filed: 1959-06-15
Abstract: 862,735. High speed kinematograph cameras. BECKMAN & WHITLEY Inc. June 15, 1959 [Sept. 23, 1958], No. 20366/59. Class 97(1) A camera comprises a drum shaped housing 10, a removable cover 15 closing one circular side face of the housing, a drum-shaped film transport member 17 rotatable within and concentric with the housing, a motor 13 with a drive shaft 14 extending into and supporting the film transport member 17, and optical elements supported entirely by the cover for forming an image of an external object on a film 18 disposed on the inner cylindrical surface of the film transport member. As shown, the optical elements include a hexagonal mirror 25 driven through a gear box 42 carried by the cover 15 and arranged with its operative face is close to the axis of the drum so that the reflected image formed on the film 18 moves in synchronism. Light from an external object through objective 20 is reflected by a mirror 23, which is rotatable to permit finding and focussing by means of the sight tube 35, to a mirror 24, hexagonal mirror 25 and then via either of two relay systems each comprising lenses 26 or 261 and a periscopic pair of mirrors 27 or 27<SP>1</SP> so as to form alternate images in separate ranks as shown in Fig. 4. Diamond apertures are disposed at 30 (Fig. 2) and 31, 311 (Fig. 3) to prevent frame overlap. The hexagonal mirror may rotate in the same or the opposite direction as does the film depending on whether the objective 20 and lens 24 form an image before or after reflection in the rotating mirror. The gear box 42 has a splined shaft connection at 48 with the drum driving shaft 14 so that the gear box carried be readily disengaged when the cover 15 is removed. The mirror rotation also rotates a magnet to induce a current operating a meter 41 indicating frame speed controlled by adjustment of the motor 13.
Patent GB-870691-A (GB)
Title: A method of processing fuel material of nuclear reactors
IPC: G21C19/48
Filed: 1959-06-15
Abstract: A uranium or plutonium mass is dissolved by adding an alkali metal-aluminium double chloride and heating to 260-800 DEG C.  When the mass treated is a spent uranium fuel from a nuclear reactor, plutonium and fission products are separated by adding aluminium metal (if not already present), to form two phases, a metal phase containing uranium and a salt phase containing plutonium chloride and fission product chlorides.  The fuel treated may be an oxidic mass or a uranium-aluminium alloy.  The process may be carried out in quartz, platinum, or tungsten crucibles in the presence of air, or, in order to prevent the formation of aluminium oxide, an inert gas containing a carbon halide may be passed through the melt; nitrogen, argon, and helium are suitable inert gases, and carbon tetrachloride, carbon tetrabromide, and carbonyl chloride suitable carbon halides.  To separate the two phases, the mass may be partially cooled and the molten salt phase removed from the solidified metal.  Plutonium is recovered by dissolving the salt phase in acid, followed by solvent extraction or precipitation; alternatively, plutonium metal is obtained by reducing the salt phase with metallic calcium and/or magnesium.  Examples describe the dissolution of uranium oxides, plutonium oxide, uranyl chloride, and uranium metal in potassium-aluminium chloride. Other examples show that plutonium, thorium, and cerium go into the soft phase when aluminium metal is present.

Abstract: 217,466. Urquhart, A. Aug. 14, 1923. Chucks.-A tool or work chuck, which may be mounted in a hollow-spindle lathe, consists of a body 1 and an internal slit sleeve 2 rotatable within the body but restrained from end movement by flanged plates 4 engaging grooves in the chuck body. The sleeve is mounted in ballbearings and is closed on the work by relative rotation to the chuck body, causing a series of balls mounted in a spiral on the sleeve to oact with the wedge surface of a similar spiral 10 on the interior of the chuck body. In a modification the balls may be carried in the chuck body and the wedge-section spiral formed on the sleeve. Stops 12, 13 carried respectively in the sleeve and the body may be provided to limit the relative rotation of these parts, and a handwheel 21, Fig. 5, loose on the body may be fitted for actuating the chuck. The handwheel has a recessed hub engaging the stop 12, and is locked to the body in the tightened position by a handlever 30 which actuates an eccentric connected to a draw-pin 26 passing through lugs on the hub of the handwheel. Slit bushes of different sizes may be inserted in the sleeve and may be retained in axial position by a spring-pressed pin 16, Fig. 4, which engages a groove 18 in the bush when the head of the pin has been pressed and turned so as to engage. a stop 20.

Abstract: 1472477 Nuclear reactor containments; handling reactor components NUCLEAR POWER CO (WHETSTONE) Ltd 6 May 1975 20907/74 Heading G6C A nuclear reactor installation comprises a pressure vessel 12 enclosed within an outer envelope constituting secondary containment means and an external missile protective shield, and a plurality of auxiliary-facility stations disposed outside the outer envelope wherein the outer envelope comprises a lower wall portion 21 surrounding the pressure vessel 12 an annular portion 22 integral with the lower wall portion 21 and extending outwardly therefrom and an upper portion 23 integral with the annular portion 22 and extending over the annular portion and over the pressure vessel 12 the annular portion and the pressure vessel being formed with sealable vertical penetrations (for example core access standpipes 12<SP>1</SP>, a containment access penetration 46 and other penetrations 33, 34) communicating with the pressure vessel interior and the respective auxiliary-facility stations and there being provided handling means for lifting reactor components vertically through such penetrations and transporting them over the said annular portion 22 and the pressure vessel 12. The upper portion of the outer envelope is constituted partly by a dome 23 and is supported by a part-annular wall 24 (Fig. 5). A space between this wall 24 and the lower wall portion 21 of the outer envelope accommodates certain of the auxiliary-facility stations namely a facility 39 (Fig. 5) for the assembly seal-changing and drop-testing of standpipes and a control-rod storage and maintenance facility 43. Other facilities each have a part disposed within the said space and another part extending through an opening in the outer annular wall 24. For example a shielded facilities block 29 contains a bay 30 for the reception storage and preparation of new fuel, a bay 31 in which new fuel is assembled and a loading bay 32 (disposed below the platform 22 and between the wall portion 21 and the wall 24) from which fuel columns can be picked up. Also provided is a spent fuel transfer machine 35 and a spent fuel store 37. Another facility comprises an access bay 52 by which heat exchangers 51 and coolant circulators can be transferred into or out of the outer envelope. Within the outer envelope, the platfrom 22 supports a number of fixed tracks each of which movably mounts a handling machine; also, a polar gantry 19 having a vertical axis of rotation disposed in alignment with a vertical axis of the pressure vessel 12, can carry any one of the handling machines. Thus, by means of the gantry and the respective fixed tracks, each auxiliary facility is accessible by its associated handling machine which can be moved on to the polar gantry and thus traversed across the top of pressure vessel 12.
