Title: Improvements in or relating to electron beam tubes
IPC: H01J25/36
Filed: 1963-10-02
Abstract: 994,507. Electron beam parametric amplifiers. SIEMENS & HALSKE A.G. Oct. 2, 1963 [Oct. 3, 1962], No. 38737/63. Heading H1D. An electron beam tube for frequency multiplication of an input signal comprises an input coupler 3, a multiple 7 having an even number of electrodes greater than four disposed symmetrically about the beam axis and extending parallel to the axis, means for applying one direct potential to alternate electrodes of the multipole and for applying an equal and opposite direct potential to the other electrodes, and a catcher system in which in operation an output signal is produced from the beam, a magnetic field being applied along the direction of the axis. The signal wave of frequency # 0  is applied to the input coupler which is in the form of a delay line and induces a cyclotron wave on the beam. Between the coupler and the multipole the axial direction of the magnetic field is reversed and the cyclotron wave mode changes to a synchronous wave mode. With # pairs of conductors forming the multipole, the positive energy input synchronous wave of frequency # 0  inducts a negative energy synchronous wave of frequency (n-1)<SP>2</SP> # 0 , which in turn induces a positive energy wave of frequency (n-1)<SP>2</SP># 0 . Waves of higher frequency may be produced, their general frequency being (n-1)m# 0 , where m = 1, 2, 3 . . . The multipole structure also amplifies any one of the synchronous waves formed. A desired frequency output is obtained by connecting an output catcher tuned to the desired frequency directly to the multiple. Positive energy waves of the desired frequency will be coupled out as soon as they are formed within the multipole, and thus higher frequency waves will not be produced. A suitable six-pole structure, Fig. 4, comprises alternate rodshaped electrodes 12, 13, 14 and comb-like electrodes 15, 16, 17, the teeth of which are directed towards the axis of the structure and lie on a helical path. In other structures, all the electrodes are rods except at least two symmetrically disposed comb-like electrodes.

Title: Nuclear reactor including a package safety device
IPC: G21C9/02
Filed: 1957-12-13
Abstract: 852,366. Nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Dec. 13, 1957 [Feb. 6, 1957], No. 38750/57. Class 39(4). A safety device for a nuclear reactor comprises a tube containing a first chamber and a second chamber, the first chamber containing moderator material and being adapted to be located at a position within a reactor where neutron absorbing material has a large effect on the reactivity, the second chamber being adapted to be located at a position within a reactor where neutron absorbing material has little effect on the reactivity, the second chamber containing at high pressure a gas having a high neutron absorption cross-section, a barrier separating the first and second chambers, and means responsive to the neutron flux within the reactor for rupturing the barrier. As shown in Fig. 5 a stainless steel tube 120 may be divided into two chambers by a stainless steel ring 136 surrounding a copper disc 138 to which is attached a body 140 of 90% uranium 235. The upper chamber is filled with a neutron absorbing gas such as helium 3 and may be provided with an internal coating 134 of cadmium to protect the gas from deterioration due to neutron bombardment. The lower chamber may be almost completely filled with a moderating material such as beryllium or graphite. The device is situated in a reactor with the lower chamber adjacent the fuel elements and the upper chamber above the level of the fuel elements. If the neutron flux in the reactor rises too high, the block 140 generates sufficient heat to melt the copper disc 138 and allow the gas in the upper chamber to expand into the lower chamber and thus reduce the reactivity of the reactor.

Title: Apparatus for feeding a workpiece between rolls
IPC: B21H1/22
Filed: 1963-10-02
Abstract: 1,017,467. Rolling. MASCHINENFABRIK HASENCLEVER A.G. Oct. 2, 1963, No. 38764/63. Heading B3M. A work feeding device suitable for use with forging rolls has a work gripper which is connected to servo motor means for automatically feeding the work at substantially the same rate as the rolls move the work. A workpiece 3, held by a gripper 4 for rolling between rolls 1 and 2 in response to movement in direction C caused by initial contact with working rolls 1 and 2, is fed in the same direction by an hydraulically controlled movable slide. Movement of a slide 10 which carries the gripper 5 is controlled by the position of a spool 6 formed integrally with the gripper, the spool determining the quantity of fluid supplied to either side of a fixed piston 13 about which the slide moves. Hydraulic fluid is supplied from a conduit 30, through a conduit 17 to a fixed piston rod 14, and through conduits 19 and 20, to act on both sides of a piston 13 in a bore 11. As the workpiece is initially moved to the right, however, conduit 19 is closed by a shoulder 22 on a spool 6, so that fluid is supplied only to the right of piston 13, and so that conduit 20 is vented to an exhaust port 21. The slide 10 thus moves to the right. Should the slide move too fast relative to the slider 6, and hence the workpiece, the conduit will again be opened and the driving force supplied to the slider will cease. Thus the slider follows the feeding of the workpiece and avoids compressional or tensional stresses in the rolled workpiece. Air from a reservoir 45 is directed by a lever 62 to the right of the slider 6 when rolling is completed to cause movement of the slide 10 back to its original position. The frame 12, including the slide 10 can be moved laterally by an hydraulic piston-cylinder assembly to align the workpiece with further roll pairs mounted coaxially with rolls 1 and 2.
