Title: Improvements in or relating to methods and apparatus for weighing substances in sealed-off containers
IPC: G01G7/04
Filed: 1960-11-18
Abstract: 902,718. Automatic control systems. SARTORIUS-WERKE A.G. Nov. 18, 1960 [Nov. 18, 1959], No. 39621/60. Class 38 (4). [Also in Groups XVIII and XL (b)] Apparatus for weighing substances in a sealedoff space comprises a balance with its load side divided into two mechanically unconnected pendent parts, the lower of which can be located in a sealed-off container 10 and the upper outside, and with a magnetic system for quasirigidly coupling together the upper and lower parts by magnetic attraction, controlled to maintain a constant gap between the upper and lower pendent parts by electronic means. The part of the magnetic system in the upper pendent part comprises a magnet 4, polepiece 5, core 6, indicator coil 8 and control coil 9, all in a soft iron pot-shaped member 7. The part of the magnetic system in the lower pendent part comprises a magnet 11 in a soft iron potshaped member 12 which is soldered to a copper plate 13. Mounted on the base of the pot 12 is a rod 14 which, from a hook 15, supports a dish 16 containing the substance to be weighed. The coil 8 is connected in circuit in an inductance measuring bridge with an oscillator, rectifier, amplifier and output amplifier included in the circuit so that, when a change of inductance takes place in the coil 8 by relative movement of the copper plate 13, an A.C. signal is amplified and rectified and fed to the control coil 9, whereby the magnetic field in the upper pendent part is altered in such a manner as to compensate for relative movement between the upper and lower pendent parts and to keep the gap between them substantially constant. A time-constant circuit is included to counteract any tendency to swinging. In a modification, the coil 9 is controlled from a photo-electric cell (with an amplifier) 25, Fig. 3. Light from a lamp 21 is directed, by a condenser 22, through a shutter 24 mounted on the lower pendent part and thence, through a lens 23, to the cell 25. Either the optical system is mounted on the upper pendent part or, if it is mounted on the housing, a second shutter is mounted on the upper pendent part. In yet another modification, a capacitor system is used, with one plate stationary and the other plate on the lower pendent part, the capacitor system being electrically connected to the coil 9 to control the magnetic field to maintain a substantially constant gap between the two pendent parts.

Title: Improvements in or relating to nuclear reactors
Inventor: KENDALL JAMES WILLIAM
IPC: G21C1/12
Filed: 1947-02-14
Abstract: 821,221. Nuclear reactors. UNITED KING- DOM ATOMIC ENERGY AUTHORITY. Feb. 26, 1948 [Feb. 14, 1947], No. 4321/47. Class 39(4). A nuclear reactor comprises a mass of moderator material, fissile material distributed in the moderator, and means for establishing a flow of cooling fluid through the mass with a flow velocity greater in the hotter regions of the mass than in the cooler regions. Fig. 1 shows part of a moderator structure built of graphite bricks 1 and provided with horizontal fuel and coolant channels. The lower boundary walls of these channels are constituted by chamfered top edges 1a of the graphite bricks in one horizontal course and by V-shaped grooves 2a in the upper faces of the graphite bricks in the next horizontal course. The upper boundary walls are constituted by rectangular grooves 2b and rabbets 1b on the under sides of the bricks ; these grooves and rabbets are made shallow in the bricks in the middle of the moderator to increase the flow velocity of the coolant, but the outer channels may have a uniform cross-section. The moderator is surrounded and covered by a rectangular housing, as shown in the sectional drawing of Fig. 4, comprising reinforced concrete 6a clad in steel plates 6b and lined with massive iron plates 6c. Barytes may be included in the concrete mix to increase the radiation absorption of the shield. Spacers 7 and 8 between the shield and the moderator constitute inlet and outlet headers for the coolant gas, and the shield has a small clearance with respect to the other faces of the moderator. Channels 9 of stepped diameter and constituted by lapping steel tubes are provided through the shield in alignment with the channels through the moderator, and aluminium tubes 10 are fitted across the header spacers between the channel 9 and the fuel channels. Thus a straight passage is provided completely through the reactor from the charge face to the discharge face to allow fuel elements 4 to be moved into and out of the reactor. Openings 10a in the tubes 10 allow gas to pass from the inlet header into the fuel channels, and from the fuel channels to the outlet header. The channels in the discharge face of the shield are normally stoppered by plugs 11 comprising steel tubes filled with concrete ; similar plugs 12 in the charging face are provided with tubular extensions 12a having oblique ends which cover the openings 10a to an extent adjustable by rotating the plug. Thus each plug in the charging face comprises a control valve for the coolant gas flowing through the corresponding fuel channels.

Title: A process for liquid phase pelleting of thermoplastic resins and apparatus therefor
IPC: B01J2/20
Filed: 1957-02-08
Abstract: 833,702. Making thermoplastic pellets by extrusion. UNION CARBIDE CORPORATION. Feb. 8, 1957 [March 9, 1956], No. 4449/57. Class 87(2). A method of making pellets comprises extruding strands of molten thermoplastic, e.g. polythene, material directly into a cooling liquid and cutting the at least partly congealed strands, whilst still in the liquid, into pellets. The liquid may be water, a mixture of water and glycol or a saline water solution of a greater relative density than the thermoplastic material. Resin from an extruder is fed through a conduit 15 to an annular chamber 13 between cylinder walls 10, 11, heated by fluid in passages 11 and coils 18, and is forced through a circularly arranged series of extrusion orifices 23 and is cut into pellets by knife blades 36 mounted on a conical member 31. The orifices 23 are heated by annular fluid passages 24 which transmit some of their heat to the liquid causing it to rise, with the lower density pellets, to overflow through veins 50 of the enclosing chamber T and to flow by gravity down a collector 51 where the pellets are separated and the liquid returned to the chamber T through a pipe 53. The knives 36 may revolve or oscillate and extrusion may cease during cutting of the strands. The knives are adjustable vertically by means of a nut 46 on the shaft 30 supporting the conical member 31. The movement of the knives in the liquid dislodges the pellets which are kept separate by the liquid. The die orifices may be at a temperature of 110-160‹C., the temperature in the chamber 13 may be 125- 260‹C., the extruding pressure may be from 200 to 3,000 pounds per square inch, and the liquid may have a temperature of 80‹C. Reference has been directed by the Comptroller to Specification 774,681.
