Title: Improvements in or relating to retarding mechanisms
Inventor: LOCKETT GEORGE EDWARD
IPC: G21C7/20
Filed: 1964-04-06
Abstract: 1,028,886. Jacks. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 2, 1965 [April 6, 1964], No. 14198/64. Heading B8J. [Also in Divisions F2 and G6] Mechanism for raising and subsequently retarding the descent of a control rod 11 of a nuclear reactor comprises a spider 12 attached to the lower end of the control rod, the spider consisting of three arms each provided with an inner roller 14 and an outer roller 15, and two concentric tubes 16, 21, the former of which is fixed via a separate flange portion to a casing 9 and provided with straight axial slots 16a in which the rollers 14 slide, while the latter is rotatable on bearings 20, 22 and has slots each of which comprises a straight portion 23a and a helical portion 23b, to receive the rollers 15, so that, on descent of the control rod, as it approaches its lower position, the tube 21 is rotated and drives, via a compound epicyclic gear, a flywheel 25, which absorbs the kinetic energy of the control rod. Just before the rod 11 reaches its lower position, the rollers 15 drop out from the lower ends of the slots 23b to disengage the drive so that the flywheel spins freely, the rod coming to rest on a spring-loaded buffer stop 19. The mechanism for raising the rod from its lower position in which the neutronabsorbing part 8 (Figs. 1 and 2, not shown) is disposed at B in the reactor core 5, to its upper position where the part 8 is disposed at A in the reflector 6 and shield 7, consists of a nut 13 which engages a threaded portion 11a of the rod and is driven via a sleeve 29 having a splined connection 30 with a driving sleeve 31, from a reversible electric motor 33 which drives the sleeve 31 via a worm 32. Raising is carried out in two stages. First the sleeve 29 is raised by rotating the nut 13 in one direction until a magnetizable ring 38 carried on a bearing 35 at the lower end of the sleeve is brought into contact with the core of an electromagnet carried by the casing 9, upon which a controlling rod 40 engaged by ring support 39 actuates a switch (not shown) to energize the magnet winding 41, then the motor is reversed so that the control rod 11 is raised with the sleeve 29 held in raised position by the electromagnet. A spring 36 absorbs any overwind torque when the sleeve 29 is fully raised and the motor 33 co-operates with a torque-limiter switch 34 (Fig. 4, not shown) to prevent overwind in the opposite direction. The raising mechanism and retarding mechanism are completely enclosed by the casing 9 which is joined to a tube 1 (Figs 1 and 2, not shown) embedded in concrete wall 2 of the reactor, an extension tube la passing through the core bed plate 3 into the bottom reflector 4 of the reactor.

Abstract: 1421244 Welding by fusion MITSUBISHI JUKOGYO KK 23 March 1973 14230/73 Heading B3R In butt-welding together the edge of a laminated metal body to the edge of another laminated or a non-laminated metal body, weld metal is deposited in lines extending obliquely to the lamination edges, so as to avoid inter-laminate cavities between the laminated body and the weld metal. In Fig. 5, two laminated plates 17, 17<SP>1</SP> are butt arc welded together by a consumable electrode wire 18 fed so that the direction of each deposited layer 19 makes an oblique angle a to laminate interface lines 32. A cooling strip 20 avoids flow of molten metal out of the welding gap and shapes the molten metal. Shielding gas may be fed through the strip 20. Deposited backing metal 21 is welded to the lowermost edge of each laminate, or a second, lower, cooling strip. In this embodiment, the description refers to the use of shielding gas of 50% A+50% CO 2 , and to procedures to reduce a to a minimum, in particular by introducing short (10-15 seconds) rest periods between each pass. In Fig. 7, cylindrical laminated tubular members are butt arc welded together using a consumable electrode wire 28 together with a cooling strip 29. The angle a referred to is that which the innermost laminate line 33 makes with each deposited layer 31, and the smaller the angle α, the greater the weld length per pass. In this embodiment the Specification refers to both submerged-arc and gas-shielded arc welding. The specification refers to laminated tubular bodies comprising spirally wound strips or multiple layers of hoops. The Specification includes description of prior arc welding of laminated tubes end-toend by conventional circumferential welding (Figs. 1-3, not shown) and by circumferential welding using buttering layers (Fig. 4, not shown).

Abstract: A chain saturated polymer, particularly an elastomer, at least half fluorinated and composed substantially exclusively of carbon, hydrogen, and halogen atoms, is cross-linked by heating in the presence of an organic peroxy-type compound which is relatively stable at temperatures below 50 DEG  C. and in the presence of a basic metal compound.  The polymer is preferably a copolymer of a highly fluorinated mono-olefin such as those of formul  CF2= CFCl, CF2=CCl2, CF3-CF=CF2, CF2=CHCl, CF3-CCl=CCl-CF3, CF2=CHF, CF3-CH= CH-CF3, CF2=CF2, <FORM:0774947/IV(a)/1> CF2=CFBr, CF2=CCl-CF3, CF3-CH=CH2 and CF3-Cl=CCl2, and a hydrogen-containing mono-olefin such as ethylene, vinyl fluoride, chloride or bromide, vinylidene fluoride or chloride, 1,1-fluorochloroethylene and <FORM:0774947/IV(a)/2> The peroxy-type compound may be ditertiary butyl, dilauryl, dibenzoyl, or p-chloro-dibenzoyl peroxide, cyclohexanone or ditertiary butyl hydroperoxide, ditertiary butyl perbenzoate or diperphthalate, or tertiary butyl permaleate or perlaurate.  The basic metal compound may be magnesium, calcium, zinc or lead oxide, magnesium or calcium carbonate, calcium acetate, tetraphenyl tin, tetraethyl lead or sodium methylate.  The cross-linking agents may be incorporated into the polymer by mechanical mixing, in solution, when the basic metal compound may remain in suspension, or in an emulsion; the reaction may also be effected by maintaining thin sections of polymer in contact with a mixture of the peroxy-type compound and the basic metal compound at elevated temperatures.  Films may be obtained by applying to a surface a solution containing the polymer, and cross-linking agents, drying and heating.

Title: Operation of aircraft control flaps
IPC: B64C13/02
Filed: 1946-05-13
Abstract: 611,942. Aircraft control systems. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G., and LLOYD, J. May 13, 1946, No. 14460. [Class 4] The link 27 from the pilot's controls is connected to a control flap 12, such as all elevator, aileron, rudder or elevon through spring means and is connected to a tab 15 on the flap through irreversible gearing including an epicyclic train so that the relative movement of the tab and the flap causing the tab to assist' the flap's controlled motion depends on the extent to which the spring means is stressed by the aerodynamic force on the flap. Link 27 is secured to a lever 26 fast with a torque rod journalled in bearings 24 and carrying a lever 22 operating the flap 12 by means of a link 21. The link 27 is also connected by a link 28 to a lever 25 mounted on a shaft 30 coaxial with the hinge of the flap 12 and rotation of which relatively to a casing 32 on the flap 12 causes movement of the tab 15 relatively to the nap by means of irreversible gearing in the casing. The gearing comprises an annulus on the shaft 30 which engages planet wheels 31 carried by the casing 32 and engaging a sun wheel 33 on a shaft 34 carrying a bevel gear 35 in engagement with a bevel wheel 36 operating a screw system to move connection 18, linked by a member 17 to the tab, axially. The screw system, Fig. 4, comprises the connection 18 in threaded engagement with a member 40 which in turn has 'threaded engagement with a member 43 screwed inside' the bevel wheel 36. Thus rotation of wheel 36, as' already described, or of pinions 41, 44 secured to members 40,"43 respectively will cause axial movement of member 18 which is held against rotation by its connection to the link 17. The pulleys 41, 44 may be connected by chains to trimming controls and to a control for one of the forms of movement of elevons on a tail-less aircraft. Specifications 383,590 and 555,635 are referred to.

Abstract: 1,141,102. Tubular heat exchangers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 20 March, 1967 [1 April, 1966], No. 14615/66. Heading F4S. A heat exchanger intended for use in a steam turbine installation, comprises an outer tubular casing through which extends a tube bundle consisting of a multiplicity of continuous metal tubes having an external diameter of less than 0À15 ins., said tubes being hermetically sealed at each end of the casing into a header plate positioned across the casing end section and also to spaced-apart partitions within the casing to form at least four separate chambers, whereby fluid introduced through suitable openings can be brought into heat exchange relationship with fluid in the tubes separately from the fluid introduced to the other chambers. In the form shown a collar 80 of polygonal outer section is placed around the requisite section of each tube 12 allowing the tubes to be contiguous with one another when clamped by a surrounding ring 84 (Figs. 2-4). Alternatively the tube ends are expanded to a hexagonal outline (90, Fig. 5) so that when the expanded sections are contiguous the tubes are spaced apart by the required distance. In another arrangement the header plate or partition comprises a stack of identically similar laminations (Fig. 6) apertured to receive the tubes. In another form (Fig. 8), the header or partition is produced by a matrix of particulate, woven or unwoven, stranded or fibrous material. In Figs. 9-13, (Figs. 10, 13, not shown) the header/partition is formed of a plurality of recessed or apertured members each forming a part of the area of the header/partition, e.g. strips (102), and the opposite faces of which include a plurality of spaced apart semicylindrical recesses 109, so that when the strips are stacked, corresponding recesses are aligned to define bores for receiving the ends of the tubes, the strip assembly defining a circular periphery for insertion in the casing. Similarly, instead of individual strips, the strips can be spirally wound (Fig. 11) so that the bores for receiving the tube ends are defined by the recesses in one layer and the contiguous surface of an adjacent layer. In another embodiment (Figs. 15-17) the tube ends are held tightly together in mutual contact by means of a suitable clamping arrangement, pressure then being exerted on the ends of the tubes to splay out the regions of the tubes between the clamping means, suitable spacers then being inserted. In all embodiments so described, each assembly is finally brazed, so that all the interstices become filled with the brazing material to form a solid and hermetically sealed assembly. The arrangement of the various chambers in the heat exchanger described (Figs. 1a, 1b, 1c).
