Abstract: 857,556. Electrolytic apparatus. PROCEDES ROVAC. May 28, 1958 [June 21, 1957], No. 17090/58. Class 41 An apparatus for electrolytic, chemical or like treatment of parts comprises a battery of tanks arranged in a circle, at least two uprights independently, rotatable inside the battery of tanks about a vertical axis through the centre of said circle, an arm articulated in each upright about a horizontal axis and arranged to carry a part or parts to be treated, separate stepping means for bringing each upright in front of each of the tanks in turn by rotation and separate dipping means for immersing the parts into or withdrawing them from the tanks by rocking the associated part-carrying arm downwards or upwards in relation to the upright. As shown (Figs. 1 and 2) the apparatus comprises a battery of tanks 1, arranged in a circle, a central fixed shaft 2 and two uprights 3 mounted on shaft 2 by means of bearing collars 7. On each upright 3 is disposed a part-carrying arm 9, having a perforated and non-metallic drum 12 mounted rotationally thereon. Drum 12 is solid with shaft 13 terminating in pinion 14 (Fig. 3) which is in mesh with tangent screw 15, which latter is driven from motor 17 by transmission 16. Each upright 3 is driven about shaft 2 by jack 21 whose piston is connected to shaft 23 terminating in finger 24 which engages ratchet wheel 25 fixed on shaft 2. Circular rim 29 carries stops 30 and retractable panels 31. Upright 3 carries jack 33 whose piston carries finger 34 adapted to engage the space between stop 30 and panel 31 to position the upright 3 opposite each tank. Upright 3 comprises mechanism to position drum 12 in each of 3 stable positions:-position C, in which the drum dips into a tank, position D wherein the drum can be moved horizontally in transference from one tank to another, and position E wherein it is inclined upwardly for loading and unloading. This movement is effected by jack 35, piston rod 37, and connecting rod 38 which is solid with arm 9. By operating the relevant jacks drum 12 can be made to assume the loading position, then to dip successively for the requisite period of time into each of tanks 1 and then to assume the unloading position. The jacks are operated by compressed air. A slide valve distributer may be provided to control the feed to the several jacks, the distributer being controlled by electro-valves which latter are controlled by a timeswitch whereby the entire cycle of operations may be carried out automatically and continuously.

[Class 44] In a door fastening, particularly for vehicle doors, in which a bolt is operable either by an inside handle or by an outside handle, the handles being mounted on separate axes and actuating the bolt through an intermediate member, the latter is moved to a position clear of a follower or the like on the spindle of the outside handle by reverse rotation of the inside handle so as to render the outside handle non-effective. The spring urged sliding bolt a is actuated by movement of a pivoted intermediate member c when the latter is actuated either by a follower d on the spindle of the outside handle, or by a follower e on the spindle of the inside handle. Reverse rotation of the latter moves the member c into the position shown in broken lines, in which it is clear of the follower d. The follower e is held in its two alternative positions by the engagement of a spring i in notches j.

Abstract: 1,080,833. Controlling reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 23, 1965 [April 27, 1964], No. 17458/64. Heading G6C. Rapid shut down of a nuclear reactor is effected by boric acid which is caused to flow into a vertical tube in the reactor core by pressurized air. The boric acid is contained in a vessel surrounding the core which acts as a shield. Air -is trapped in the vessel, under pressure, above the free surface of the acid. In an emergency, an outlet valve from the core tube is opened and acid is urged into the core tube by the trapped air. Subsequently, the acid may be expelled from the core tube and returned to the shield vessel and the trapped air re-pressurized by the application of an external helium source.

Spring devices.-Relates to spring suspensions for motor vehicles and of the kind comprising two coaxial helical springs arranged in a casing fixed to the chassis and operated by mechanism. arranged between the springs, connected to an axle, and adapted to act upon movable caps to compress the springs ir. such a manner that resistance to relative movement between the chassis and axle is increased at a quicker rate than the rate of increase of the movement. According to the invention, which is also applicable to the frames and forks of motor-cycles, both springs act simultaneously and the force acting on the caps to compress the springs is exerted in a direction practically along the axis of the springs. In one arrangement, the springs o, p, Fig. 1, are arranged in tubular holders m, n fixed in a casing h and are acted upon by movable caps r, s. A lever c, connected to the axle, is pivoted to the casing h at a point between the springs o, p and carries an arm b which bears, by means of suitable rocking or rolling surfaces b<1>, a<1>, on a lever a pivoted at one end a<2> to the casing. The other end of the lever a carries a pivot v connecting the adjacent ends of links t, u the other ends of which bear against a cap s and holder n respectively. The cap r is moved downwards by a distance piece y mounted on the link u. The arrangement, offers no resistance to rebound. Two such arrangements may be combined to serve as a suspension as shown in Fig. 4, or a single, arrangement may be used in conjunction with a laminated spring suspension. In another arrangement which resists shock and rebound, a rotary cam device connected by a lever to an axle, is arranged between caps bearing against the adjacent ends of the coaxial springs.
