Title: Improvements in or relating to Rocket Launchers
Inventor: CHOATE PAUL VINCENT
IPC: F41A1/08
Filed: 1968-02-13
Abstract: 1,196,563. Rocket launcher. NORRIS INDUSTRIES Inc. 13 Feb., 1968, No. 7135/68. Heading F3C. A rocket launcher comprises two telescopic sections 10, 11 one 10 of which forms the breech end of the rocket launcher. The section 10 has a rigid member 20 attached thereto which member 20 overlies the section 11. A firing mechanism comprises a firing member 34 which is movable relative to the section 10 between a cocked forward position and a firing position. The cocking is effected during extension of the sections 10, 11 when the rigid and firing members 20, 34 are interconnected for movement with the section 10 by a pivoted latch 42. Towards the end of the extension movement of the two sections the firing member 34 is releasably connected to a trigger 22 so that the firing member is locked to the section 11 and a cocking spring (Figs. 1, 9, not shown) is compressed. A safety 30 is movable to disengage the latch 42 from the members 20, 34. In the construction shown the firing member is provided with a firing pin portion which cooperates with an igniter mounted in a pocket of the section 10. The latch is urged in an anticlockwise direction by one end of a spring 46, the other end thereof engaging a lock 47 which locks the sections in their telescoped conditions. The rocket launcher is shown as adjusted to discharge subcalibre rockets. To this end a tubular member 74 is mounted in the section 10 by three discs 75 (Fig. 9, not shown), 76, 77. The disc 75 includes an electric terminal for firing the rocket, the impulse being generated by a magneto 91 mounted on the disc 75. The magneto 91 which comprises a spring-loaded, slidable actuator 92 is actuated through a linkage 102, 103, 99 by a part 106 depending from the firing member 34. A lost motion connection is provided between the rod 102 of the linkage and the depending part 106 such that the part 106 is accelerated before it engages the rod in its firing stroke. A firing impulse is not imparted to a rocket in the launcher on cocking of the firing mechanism as the output of the segments is earthed through a switch 112 which is controlled by an arm 113 of the latch 42. A foresight and a backsight 51 are folded within the rocket launcher in the telescoped condition thereof but are spring-loaded to an erect position on extension of the rocket launcher.

Abstract: 704,500. Oil gas generation. UNITED ENGINEERS & CONSTRUCTORS, Inc. March 21, 1952 [March 29, 1951], No. 7313/52. Class 55 (2) A cyclic process of manufacturing oil gas comprises, in a heating period, forcing an ignited mixture of fluid fuel and air downwardly from the top of a combustion zone 2 and withdrawing the products through an outlet at the. top after having descended and reversed their flow so as to store heat in the zone, the products then passing to a stack 4 through refractory heat storage material 3, and in a make period vaporizing oil in zone 2 to which steam may also be admitted and passing the vapour through the refractory material to convert it into a fixed gas. In the form shown air for the heating stage is supplied through a pipe 6 and oil through pipes 8, 10. In the make stage the same or a different oil is introduced through the same pipes or through branches 8a, 10a; steam may also be admitted through inlets 14 or 16. In another form two refractory filled chambers are grouped at the side of the combustion chamber through which the products pass in series, e.g. down the first and up the second; steam, fuel, air and make oil inlets may also open into the first refractory chamber, and the refractory material may be dispensed with. A short steam purging period is preferably interposed between the stages. To dilute the final gas, combustion products may be added or preferably the products from a brief stage of incomplete combustion are utilized. U.S.A. Specification 2,247,336 is referred to.

Title: Nuclear reactor with integrated heat exchanger
IPC: G21C1/00
Filed: 1968-02-15
Abstract: 1,208,616. Reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. 15 Feb., 1968 [24 Feb., 1967], No. 7477/68. Heading G6C. An integral nuclear reactor has at least one off-centre extraction opening at one end of its prestressed concrete pressure vessel for the insertion or withdrawal of any one heat exchanger unit, a support for these units being coaxial with the vessel and rotatable about the axis of the vessel so as to bring any one unit into a position opposite to an extraction opening for withdrawal of the unit from the pressure vessel and for substituting another unit in the vacated operating position on the support. In the embodiment shown in Fig. 4, all the heat exchanger units 10 are connected to a single central manifold 44 which is of annular shape and disposed around a passageway 4 provided for a fuel element handling device 5. The manifold 44 extends outwardly through the pressure vessel wall in a series of conduits 46 which are connected to the heat-removal circuit by means of flanges 48. The number of conduits 46 is distinctly smaller than the number of heat exchanger units 10. The assembly of manifold 44 and conduits 46 is fixed inside a tube 50 which is rotatably mounted in the top wall of the pressure vessel. Outside the pressure vessel, the tube 50 is fixed to an annular member 56 supported by jacks 58 either on a stationary annular member 60 or on a ballbearing 62. The annular member 56 is provided with an externally toothed wheel 64 which is rotated by a suitable drive mechanism. By this means, the manifold 44 and the heat exchanger units 10 are rotated. Balls 74 in a channel formed partly in the pressure vessel wall and partly in the tube 50 support the rotary assembly when the annular members 56, 60 are disassembled for the purpose of renewal of the seals 61 placed within the annular member 60. Flanges 70 serve to connect each heat-exchanger unit 10 to the conduit 72 through which hot secondary fluid is discharged to the manifold 44. A biological shield plate 76 which is fixed to the manifold 44 and extends to the heat-exchanger units 10 serves to protect the operator against any residual radioactivity emanating from the reactor core during the replacement of a unit 10. By rotating the tube 50, any damaged heatexchanger unit 10 can be brought into position beneath an opening 2 in the pressure vessel, whereupon it is disconnected from the manifold 44 and replaced.
