Title: Improvements in or relating to fast nuclear reactors
Inventor: ACKROYD RONALD TUNSTALL
IPC: G21C9/00
Filed: 1962-04-13
Abstract: 958,088. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 25,1963 [April 13, 1962], No. 14348/62. Heading G6C. A reactor comprises a core of fast neutron multiplying material, below the core a bed of moderator material, and passages in the bed to receive the multiplying material in the event of its melting, the arrangement being such that the reactivity of the multiplying material, when in the bed, is reduced by absorption of moderated neutrons. As shown, a cylindrical core 11 of fuel elements of uranium enriched with its fissile isotope and/or supplemented with plutonium is supported by means (not shown) above a bed 13 of graphite containing a neutron absorber such as boron. Liquid metal coolant from an inlet plenum 14 is pumped upwardly through the core. Fast neutrons leaking downwards are moderated and absorbed by the red whilst those leaking outwards are absorbed in a breeder blanket 16. Should the core 11 melt the multiplying material flows into passages 15 in the bed where the neutron flux is moderated and absorbed. In another embodiment (Fig. 2, not shown) the lower ends of the passages 15 are open so that the molten material may pass therethrough.

Title: Improvements relating to magnetic apparatus for testing iron or steel articles
IPC: G01N27/84
Filed: 1942-10-15
Abstract: 556,888. Electromagnets. REYNOLDS TUBE CO., Ltd., and WOOD, T. W. Oct. 15, 1942, No. 14457. [Class 35] [Also in Group XXXVI] A single turn conductor in the form of a tongs is adapted to be placed over an iron or steel tube, bars or other articles so that when closed it surrounds the article and serves as a single turn loop through which current is passed to magnetize the article in order to test it for flaws by immersing in or spraying with a liquid containing finely divided magnetic particles in suspension. An insulating handle a is secured to the closed end of a casing b which is open at its opposite end to the open end is fixed a semicircular metal jaw C which is insulated from the casing and provided with a terminal d for the attachment of a cable e. A complementary jaw f is pivoted to the casing b by means of a pivot pin g which carries a flexible metal brush h arranged in contact with the adjacent face of the pivoted jaw. Another cable i is connected to the casing b, electrical connection between which and the movable jaw f is effected through the brush h. Both jaws are sheathed with insulating material. A lever m, with an insulating handle o is pivoted to the casing b by a pin k and extends through a slot n in the casing. The inner end of this lever has a pin-and-slot connection l with the pivoted jaw f a spring p tending to hold the pivoted jaw in its closed position. Alternatively or in addition a spring may be attached to the pivoted jaw f. The free ends of the jaws c, f are formed or provided with contacts q, r which in the closed position are surrounded by an insulating and heat resisting shield s mounted on one of the jaws, preferably the fixed jaw c. This shield prevents the spreading of the arc formed if the contacts are separated while carrying current. The jaws are opened by operation of the handle o, placed over the article to be tested; and allowed to close so that they form a loop around which magnetizing current is caused to flow.

Abstract: 1343495 Transferring designs XEROX CORP 12 May 1971 [15 May 1970] 14449/71 Heading B6C [Also in Division B8] A machine for transferring designs comprises a transfer wheel 17 which applies the labels carrying the designs to articles, and a label accumulator 21 which holds a supply of labels 11, separated from sheet 20 prior to transfer to wheel 17, in order that the supplying means and transfer wheel need not be exactly synchronized. The labels are detached a row at a time from the sheet, previously slit lengthwise by slitters 63, by guillotine 40, and fed to the accumulator on the upper run of endless belt 35, moving around pulleys 38, 39. A stripping finger 34 detaches the labels from pulley 38 and they collect, standing on edge, on the base 27 in the accumulator. A pick off wheel 22 removes the labels through gap 25, between base and rear wall 28, to heated shoe 30 of transfer wheel 17. Vacuum acts through slots in belt 35, pulley 38, wheel 22 and shoe 30 to hold the labels against the moving parts. Articles such as envelopes are fed by a conveyer between the transfer wheel 17 and a pressure roller (not shown). The spacing between the wheel 17 and the pressure roll may be adjustable to accommodate articles of different thicknesses. Once the designs, for instance in the form of wax impressions on the labels, have been transferred to the article, the labels are either collected in a storage tray for possible reuse as glued labels or simply destroyed.

Abstract: 998,099. Detecting liquid level by ultrasonic means. W. ROTH. April 17, 1962 [May 29, 1961], No. 14924/62. Heading H4D. A response is generated by circuits 15 (Fig. 1) when liquid 12 rises to the level of the face 16 of a transducer 10. The latter comprises a magnetostrictive element 24 (Fig. 2) biased by a permanent magnet 27 and carrying a diaphragm 22 formed with a #/4 tubular member 23 to provide effective rim clamping as described in Specification 942,202. A coil 25 energized by the output of an amplifier 31 drives the element 24 and a coil 26 supplies voltages resulting from vibration of 24 to the input of the amplifier. The coils, which are mutually screened by the presence of magnet 27 and by tubular member 23, are regeneratively connected to amplifier 31 by screened cables 32, 33 so that continuous oscillation of the diaphragm 22 may be produced by adjustment of the amplifier gain. In operation the gain is adjusted to be equal to the square root of the product of the gains necessary to produce continuous oscillation when the diaphragm is in air and when it is contacted (and consequently loaded) by the liquid thus providing a wide safety margin to ensure reliable operation. Contact of the diaphragm by the liquid is then sensed by the cessation of oscillation by means of device 35 the output of which may control an alarm, a luminous indicator or a control circuit &c.

Abstract: 673,289. Automatic alarm systems. CONFORZI, G. June 21, 1950. No. 15513/50.. Class 118 (i). Automatic fire or burglary alarm apparatus comprises an endless band bearing a recorded message and an associated signal-producing mechanism and radio transmitter, which are both energized by an alarm relay, so that signals capable of identifying the calling station are transmitted to a remote station in the case of burglary or fire. In the Figure, interruption of a ray which may extend across a doorway or window, from lamp 3 to photosensitive device 3a operates relay 4 which starts an electric motor 5 and supplies alternating current from supply terminals 1 to rectifiers 7 and 8 to supply high tension current to the valves of modulator unit B and radio transmitter C. The motor 5 drives an endless band 14, upon which is recorded information such as the address of the building concerned, past a reproducing means 15, thus providing a signal which is amplified and used to modulate the transmitter. Modulated high frequency signals are then radiated from aerial 33 to the distant police or central station. The signal may be either of the acoustic or visual type. In place of the ray and photoelectric device, a temperature sensitive device may be used to provide a fire alarm, and the apparatus may also be arranged to cause automatic operation of fire extinguishers. Batteries may be used in place of power mains, so that the apparatus could be used on a motor vehicle.
