Title: Improvements in or relating to the manufacture of electric discharge devices
Inventor: GOODCHILD FRANK DOUGLAS
IPC: H01J19/42
Filed: 1947-09-02
Abstract: 662,433. Electron discharge apparatus. STANDARD TELEPHONES & CABLES, Ltd. Aug. 27, 1948 [Sept. 2, 1947], No. 24197/48. Class 39 (i). The anode is hollow and indented to partially surround the cathode, the outer wall providing a closed eddy current heating loop in any plane perpendicular to the cathode axis. In one form of thermionic rectifier, two hollow rectangular anodes 15, with an indirectly-heated cathode 22, are mounted between mica discs 14, 18. The anode is supported on leading-in wires and secured to the discs 14, 18 through lugs 16. A getter assembly 23 is welded to the anode lug 24. In a further form, two separate cathodes, connected together internally or externally of the envelope, are each completely surrounded by an anode, which is formed of two of the anodes 15 welded together. The anode arrangement shown in Fig. 6 may be used to form the two diodes of a double-diode triode having a single cathode.

Title: Needle-gripper for engaging and transporting hollow tubular elements
Inventor: WILHELEM ANTOINE
IPC: B66C1/66
Filed: 1967-05-24
Abstract: 1,149,456. Article engaging devices for lifting. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). 24 May, 1967 [26 May, 1966], No. 24209/67. Heading B8H. To lift a nuclear fuel-element 14 a tube 2 is inserted through the interior of the element and a locking-pin 7 which holds a spring 8 compressed is released. This allows the spring 8 to expand and raise a rod 1 eccentrically mounted within the tube 2. As the rod rises it is rotated through 180 degrees by pins 13 which run in helical slots in the wall 11. This rotation moves an eccentrically mounted stop 10 out of alignment with the tube 2 into a position in which it engages below the bottom of the element 14 so that the latter can be lifted by a ring 5 on the rod 1. When the load has been set down a pull exerted on a ring 6 attached to the tube 2 rotates the rod 1 and stop 10 to their original positions and re-compresses the spring 8.

Title: Improvements relating to electrical networks
IPC: G05D3/12
Filed: 1949-09-22
Abstract: 688,626. Electric follow-up systems. EVERSHED & VIGNOLES, Ltd., and ASKEW, J. H. Sept. 22, 1950 [Sept. 22, 1949], No. 24405/49. Class 40 (i) [Also in Group XXXVI] An alternating current circuit for producing an integral function, e.g. for compensating the error signal of a follow-up control system for positional lag in the receiver element, comprises a resistance-capacitance network giving an output voltage which is a time integral of the input voltage over relatively short time intervals, with a mechanical rectifier operated at the frequency of the A.C. input to rectify the A.C. input to the network, and a mechanical switch operated at the required A.C. output frequency and connected to modulate or chop the network output into an alternating signal. Fig. 1 shows a follow-up system in which the rotor of a known transmitter T is energized from an A.C. energized transformer W, and the threephase transmitter stator is connected to the stator of a known receiver R, whose rotor develops an error signal which energizes the field of a motor M through an amplifier A to drive the receiver rotor into coincidence with the transmitter rotor. A pilot alternator G driven by the motor generates a velocity voltage for injection into the amplifier circuit to prevent hunting, and the lag of the receiver rotor behind the transmitter rotor is compensated by the injection of an A.C. voltage proportional to the time integral of the error voltage, which is derived from the network N shown in Fig. 2, wherein a polarized relay S energized at the error voltage frequency operates contacts 16 and 17 to shortcircuit the input at terminals 11, 12 on alternate half waves, the rectified voltage being applied to a network comprising the series resistance H and the parallel condenser C whose output is proportional to the time integral of the input over short time intervals. Contacts 16 and 23 shortcircuit the output on alternate half waves to chop the integrated voltage across the condenser into an A.C. voltage on terminals 26, 27 substantially proportional to the time integral of the error voltage. Separate relays, or a rotary commutator, may be used for rectifying and chopping.

Abstract: 244,863. Jones, D. A. Oct. 17,1924. Binding-apparatus.-An independent machine for packing and binding hay, straw. or corn, &c. comprises a light frame 1 of tubular members jointed together and supported by a wheel 2 and tubular legs 3. The longitudinal frame members accommodate, two shafts 4, 5, the shaft 5 being provided with a handle 6 and being connected by a crank 10 and a link 12 to a crank 11 on the shaft 4. A second link 13 extends from the crank 11 to one end of a lever 14 pivoted on the shatf 5 and at its other end connected to a U-shaped member 8 pivoted on the shaft 5 and adapted to receive the material to be bound. A pair of arms 7 is secured to the shaft 5 and these arms are adapted to move towards the member 8 to compress the material for binding. A needle arm 9 is secured to the shaft 4 and a knot-tying mechanism 16 partially covered by a shield 15 is provided. In operation the material is placed on the member 8 and the handle 6 turned to rotate the shafts. The member 8 and the arms 7 swing towards one another, the material being pushed on to the binding cord which is then brought round by the movement of the needle 9 and knotted by the mechanism 16. The movement of the shaft 5 is then reversed, permitting the bound sheaf to fall through the machine. The two shafts may be connected by a transverse shaft instead of the links and cranks and such transverse shaft may be driven from the supporting wheels of the machine. The arms 7, member 8 or needle 9 may be pivoted on the frame of the machine and actuated by cams on the shafts.

The rod 41 serves both to prevent the jaws being opened by a clamped limb approaching close to stem 38, and to prevent rotation of jaw 40 about stem 38. A stop pin 50 restricts the minimum jaw separation and thereby prevents clamping of small diameter limbs.

Source 130 is within the cone of detection 120. If a single crystal were used, as in prior art, the centroid of its response is midway bebetween the centroids 154, 158 of the separate responses. By absorbing correspondences with response patterns obtained by scanning known radiation distributions an unknown radiation distribution can be determined.
