Abstract: 1,096,045. Circuits employing multi-stable magnetic elements. HONEYWELL Inc. Dec. 13, 1964 [Dec. 13, 1963], No. 49205/64. Heading H3B. In a counting circuit, a magnetic core 40 having a plurality of stable states is supplied with pulses from a transfer circuit which includes a power amplifier and is coupled to a bi-stable core 10. An input pulse at terminals 19, 33 allows current to flow through set winding 11 to switch core 10. Collapse of the field around winding 11 when the input is removed induces a voltage in winding 29 and permits current to flow in reset winding 21 until core 10 is reset. The voltage induced in output winding 31 during resetting of core 10 switches on transistor amplifier 42 and current flows through set winding 41 to partially switch core 40. The voltage induced in winding 59 is such as to maintain transistor 52 switched off. Each successive output pulse from winding 31 causes core 40 to be switched one step further until it reaches saturation. The impedances of windings 41 and 59 then drop and the current flowing through resistor 60 increases and causes transistor 52 to be switched on. When current flow in winding 41 ceases, current flows in windings 50, 51 to reset core 40, and an output is induced in winding 61. It is shown that the final count in core 40 may be made temperature independent by suitably selecting the values of resistors 43 and 44, and resistor 23.

An apparatus for pre-piercing and scalping a billet to prepare it for extrusion comprises a ram 42 to force the billet into a container 94 against an abutment 144 to compress the billet to the size of the container, a piercing mandrel 48 slidable within the ram to pierce the billet and a scalping die 126 through which the billet is pushed after removal of the abutment. The ram 42 is mounted on a movable platen 23 and moved along tie-rods 14 by hydraulic cylinders 17 mounted on a fixed platen 10. The mandrel is moved relative to the platen 23 by a pair of hydraulic cylinders 21. The ram 42 has an axial bore 43 along which the mandrel 48 is moved. The mandrel is screwed into a holder 54 slidable in a horizontal slot in the ram and the holder 54 is bolted to a cross-head 59. The mandrel 48, holder 54 and cross-head 59 are provided with cooling ducts 62-70. The billet is initially supported in a cradle defined by adjustable pads 83, 84, Figs. 8, 8A, 8B, 8C (not shown). The billet container 94 is mounted on a fixed platen 92. The container has a tapered inner wall 95, Fig. 11, and an alloy steel liner 94a is press-fitted into the container. The container is mounted in a hole 93 in the platen 92 and the diameter of the hole is greater than the container to allow for adjustment to align the mandrel and container. The container has bores 107 to receive heating elements if desired. The scalping die 126 is mounted in a fixed platen 111 mounted on adjustable levelling blocks 111a. The platen receives the ends of the tie-rods 14. The die is bolted to a die holder 122 which is bolted to the platen. The die has three knives 132, Fig. 12 (not shown), mounted at spaced points to cut the scalped metal into segments. The abutment or gate lock 144 is positioned between the container 94 and the scalping die 126 and is slidable in guide blocks 141, (142), Fig. 10 (not shown), on the platen 111 by an hydraulic cylinder 147. The gate lock has a small central bore 149 with an annular trimmer 152 which trims the flash formed by the piercing mandrel from the billet during the raising of the gate lock. A knock-out rod 155 actuated by a pneumatic cylinder 157 serves to move the flash from the bore. In operation, a heated copper or brass billet is rolled on to the pads 83, 84 of the cradle and the ram pushes the billet into the container against the gate lock and compresses it. The ram is then retracted and moved forward with the mandrel 48 and the billet is pierced by the mandrel, Figs. 17-20 (not shown). The mandrel is withdrawn and the ram acts as a stripper. The gate-lock 144 is raised to shear the flash and the ram pushes the pierced billet through the scalping die 26. The ram finally ejects the billet to a discharge position where the billet rolls into an extrusion press loader, Figs. 21-24 (not shown).

Abstract: 1,121,333. Nuclear power plant. SIEMENS-SCHUCKERTWERKE A.G. 25 Nov., 1965 [25 Nov., 1964], No. 50238/65. Heading G6C. [Also in Division H1] A thermionic converter for use in a current supply nuclear reactor, e.g. of a space vehicle, comprises emitter and collector electrodes arranged coaxially one within the other, with opposed operative surfaces which diverge from the axis, so that relative axial movement of the electrodes varies the electrode spacing, means being provided for causing such relative axial movement to adjust the spacing, and the nuclear fuel being in good thermal connection with the emitter. As shown, a plurality of converter diodes are connected in series, each diode comprising emitter and collector electrodes 3, 4 with conical facing surfaces. Each emitter has nuclear fuel 31 embedded therein, and is centred at one end by a column of ceramic bodies 10 and at the other end by a laminated bridge 9 connected to the collector of the adjacent diode. The collectors are fitted into a tubular casing 20 with the interposition of an insulating layer 7. Ceramic-coated metal heat screens 5 are provided between adjacent diodes. Relative axial movement of the electrodes is achieved by means of displacing devices at each end of the column of ceramic bodies 10. Each device comprises an expansion rod 13 surrounded by a heating coil 130 and connected between ceramic bodies 16 which are secured within ceramic tubes 14 by breakable solder joints 172. To move the emitters relative to the collectors, both joints 172 at one end, and the inner joint at the other end are heated to melt the solder, and the expansion rod at said other end is heated to cause the desired movement, after which the three broken joints are allowed to cool to effect resealing, and the remaining joint is broken while the adjacent expansion rod is allowed to cool before resealing of this joint. Instead of using thermal expansion to cause movement, the inverse piezo-electric effect may be employed, or movement may be effected with the aid of a spindle or electric motor, and may be controlled in accordance with electric output properties of the converter. Also the displacing device at one end may be replaced by a spring. The electrode spacing may be 0À1 to 1 mm. The operative electrode surfaces may be stepped conical surfaces, or may have a helical, conical stepped configuration so that the emitter and collector of each diode interengage in the manner of screwthreads, Figs. 3 and 4 (not shown). The diodes may be with or without a caesium filling and are sealed off from the displacing devices by fluid-tight diaphragms 12. The casing 20 may be surrounded by a cooling jacket and a moderator in an insulated hexagonal casing, Fig. 2 (not shown), which may be used to form a gapless thermal reactor core construction. Similar converter fuel elements may be used in other types of reactor, e.g. rapid reactors in which there would be no moderator provided.
