Patent GB-971423-A (GB)
Title: Improvements in nuclear reactors
Inventor: DEIGHTON THOMAS
IPC: G21C11/08
Filed: 1962-09-28
Abstract: 971,423. Reactors. BABCOCK & WILCOX Ltd. Sept. 25,1963 [Sept. 28,1962], No. 36957/62. Heading G6C. In order to prevent reactor fuel elements melting when coolant circulating pumps mounted in the reactor base are being removed, a liquid cooled, liquid moderated reactor is provided which includes a vessel, containing the fuel elements, arranged in the reactor pressure vessel and capable of retaining a body of liquid in which the fuel elements are submerged upon draining the pressure vessel, the pressure vessel also containing a heat exchanger. An unusual feature is that the entire fuel element container complete with the fuel elements can be lifted from the reactor. The pressure vessel 4 is thermally insulated with glass fibre 9 and closed by a removable bolted-on dome 10. The fuel element vessel 24 includes grid plates 20, 22 for supporting hollow, square crosssection fuel elements 14, and is supported on a flange 40 of the pressure vessel and also located at its lower end by a spigot 46. The fuel element vessel acts as a thermal neutron shield. Cruciform section control rods 18 are positioned in the fuel element lattice, and withdrawable therefrom by drive means 38. Four coolant (water) circulation pumps 64 are provided. Situated between the fuel rod vessel and the pressure vessel are four ducts 52 and eight heat exchanger assemblies 76 (see also Fig. 3). Secondary coolant circulates through the tubes of the heat exchanger. Resilient stainless steel seals 58 are used at the four junctions between the ducts 52 and the fuel element vessel 24. Coolant circulation. Coolant passes from the pump 64 up through the ducts 52, downwards within the fuel element vessel around the fuel element exteriors, into a lower plenum chamber, up through the fuel element interiors to an upper plenum chamber 98, downwards over the heat exchangers and duct exteriors via ports 43, and back to the pump inlets 66. Pump servicing. After the control rods have been fully inserted, the pumps are stopped and drainage duct 75 opened; thus the pressure vessel will be emptied, but the fuel element vessel will remain full, so as to act as a heat sink for heat generated by fuel decay. Pumps can then be removed from the pressure vessel. If necessary, an auxiliary coolant circuit may be connected to the fuel element vessel. Fuel removal and heat exchanger servicing is accomplished by draining the pressure vessel, removing the top dome and withdrawing the complete fuel vessel and fuel load. still filled with coolant water. After this, heat excnanger units may be uncoupled and removed bodily through the top of the pressure vessel. The pressure vessel may be re-loaded with a replacement fuel vessel and fuel element load combined, thus reducing fuel recharging time.

Title: Decorative effects on textiles and sheet materials
Inventor: MADARAS GEORGE WILLIAM
IPC: D06Q1/08
Filed: 1955-12-23
Abstract: Textiles and sheets or films made wholly or to a substantial extent of cellulose acetate (including the triacetate) are subjected to the local application of pressure to a desired pattern and then, without any saponification step, to the application of a dye, for example, as by padding, whereby a differential dyeing effect delineated by the pattern is obtained. A swelling agent, many of which are specified, may be applied after the localized pressure application and before or together with the dye, whereby a differential puckered effect is also obtained.  Pressure may be applied by a press, stamp, brush or embossed calendar and the apparatus of Specification 752,191, whereby selected areas of the material are compressively shrunk, may be employed.  When no swelling agent is employed, dispersed, solubilized acetate, azoic and vat dyes (including acid leuco vat dyes) may be applied, followed, if necessary, by a steaming operation, the pressed portions of the material resisting the dyestuff.  When a swelling agent is applied with the dye, acid, premetallized and vat dyes may be employed, a subsequent washing removing the dye from the unpressed parts of the material.  When a swelling agent is applied before the dye, acid, premetallized and basic dyes may be employed, a subsequent drying step effecting migration of the dye to the pressed portions of the material. Two-coloured effects may be obtained by double-dyeing from the same or different baths employing dyes responding differently to the material, or by additionally dyeing the material, e.g. with a disperse dye, before the application of pressure.  The steps of applying pressure and dye may be repeated to give combination effects.  Numerous examples are given.  Specifications 301,567, 301,568 and 311,306, [all in Class 15 (ii)], also are referred to.

Title: Electron discharge devices
IPC: H01J25/76
Filed: 1938-12-30
Abstract: 523,281. Electron-multipliers. STANDARD TELEPHONES & CABLES, Ltd. Dec. 30, 1938, No. 37851. Convention date, Dec. 31, 1937. [Class 39 (i)] The cathode 20, preferably in the form of a thin walled hollow cylinder of silver with a silver-caseium oxide surface, is surrounded by the anode 30 which comprises a squirrel-cage or other openwork cylinder of a non-magnetic material such as copper or aluminium. An axial magnetic field is produced by solenoids 41, 42, or by a permanent magnet which is preferably housed in a re-entrant part of the envelope which extends downward inside the cathode, and in which the latter is supported by mica washers. When the device is used as an amplifying photo-electric device, the anode and cathode are connected across a source of high frequency potential 61, a steady biassing potential 50, and an output resistance. The photo electrons excited by the source 100, are sent back to the cathode in looped paths, and, as long as the cathode is becoming more positive, strike it with sufficient energy to release secondary electrons, which then follow a similar path. Electron multiplication continues until the potential imposed on the cathode begins to fall ; all the electrons then move outwards to the anode. For operation as an oscillator the device is connected as shown in Fig. 7 to a tuned circuit 81, which is coupled to the output circuit. Oscillations may be initiated by opening and closing the circuit and may be modulated by incident light. Alternatively the anode may be opaque and the cathode non-photo-electric, so that the device operates simply as a multiplier. The device may be mounted in a parabolic reflector to concentrate light on the cathode.

Title: Improvements in or relating to shuttles for looms for weaving
IPC: D03J5/24
Filed: 1928-12-31
Abstract: 324,491. Hutchins, A. S. Dec. 31, 1928. Shuttles. - Relates to a self threading and tensioning device designed to permit the yarn from the bobbin to be drawn through a tortuous path, which gives uniform tension to prevent kinks, snarls, slackness, or breakage by knots, and to allow the trailing weft of a used pirn to be withdrawn freely when ejection is effected. The tensioning device, which is pivotally mounted in the recess 14, Fig. 2, in the front of the shuttle, comprises a pair of tensioning- members 16, 18 having oppositely inclined portions 20a, 21a, Fig. 3, which form am entrance mouth M for the weft. The upper member 16 comprises an upper loop, having a closed end 22, and side portions 20 which curve round to form eyes 24 and continue as downwardly and outwaxdly inclined legs 20<a>. The lower member 18 similarly comprises an upwardly and outwardly extending loop having an end 23 to which forwardly extending leg portions 21 are joined by continuous curves to form the eyes 27. The eye portions 24, 27, when in position are alternate with each other. At the lower end, the legs 20<a>, 21 are bent outwards to provide pivots 25 which engage in recesses in bearing blocks 26 in the side walls of the shuttle. The tension members 16, 18 are tlso provided with offset portions 30, 32, Fig. 4, for engagement with the rearwardly-extending ends of a resilient member 33, which, looped about a projection 34 and secured at the front end of the recess 14 to an adjustable screw 35, forces the members apart. A fur or like lining is attached to one or both walls of the shuttle to provide a resistance greater than that of the tensioning device. In a modification shown in Fig. 12, the tensioning members are mounted above the mouth M by coiling the rear ends round a pin, which protrudes from the wall of the shuttle. In this case, an endless resilient band passes over the extending ends of the members and round one of a series of pins arranged in the forward end of the recess. In another modification, shown in Fig. 21, the tensioning members are mounted on separate pivots, constituted by respective pins projecting laterally from opposite walls and situated one above and the other below the mouth M. A resilient member is attached to each tension member. Means are also provided to keep the tension members on the pivots. In threading the shuttle, the thread is passed along the recess 14, over the plate P, Fig. 1, and into the delivery slot 15, during which action the thread also enters the mouth M of the device. The movement of the shuttle, in conjunction with the tension given by the fur 13, causes the tension members to move apart and allow the thread to enter the eyes 24, 27.
