Title: Improvements in or relating to nuclear reactors
Inventor: BELL JOHN DAVID
IPC: G21C3/32
Filed: 1959-08-27
Abstract: 944,699. Nuclear fuel elements. BABCOCK & WILCOX Ltd. Aug. 26, 1960 [Aug. 27, 1959 (2)], Nos. 29310/59 and 29311/59. Heading G6C. The fuel elements of a nuclear reactor comprise rods arranged in units contained within sleeves of graphite moderating material in relation to which they are withdrawable or insertable. As shown in Fig. 1, graphite sleeves 2 are joined end-to-end by means of beryllium coupling rings 10, each of which has external bayonet projections 14 of rectangular crosssection at the upper end and an internal annular flange 20 and external bayonet projections 22 of semi-circular cross-section at the lower end. The bayonet projections 14 co-operate with L- shaped slots 8 (Fig. 5) in the lower end of a sleeve 2 to position the ring within the end of the sleeve and a beryllium grid 28 is placed upon the annular flange 20 to support an assembly of fuel rods 30 which extend as far as a lower intermediate grid 32. Further fuel rods 30 extend between the grid 32 and an upper intermediate grid 34, and between the grid 34 and an upper grid 36. A further coupling ring 10 (shown in a raised position in Fig. 1) fits within the upper end of the sleeve 2, its bayonet projections 22 co-operating with further L-shaped slots 8 (Fig. 5) and rotation of the sleeve 2 relative to the ring 10 is prevented by means of a set screw 48. Each end surface 50 of the sleeves 2 is formed as a frustum of a wide angled cone and the ends of the sleeves 2 between the L-shaped slots 8 flare outwardly, which construction, together with suitable spacing of the bayonet projections 14, 22 at each end of the sleeves 2, permits a degree of articulation between the sleeves 2 when these are coupled together. When in position within the core of a nuclear reactor, the lower coupling ring 10 of the lowermost sleeve 2 rests upon a supporting stool while the uppermost sleeve 2 is connected by a coupling ring 10 to a neutron shield plug, the raising of which serves to lift the sleeves and their contained fuel rods. The fuel rods 30 comprise both thin-walled fuel rods 54 and structural fuel rods 56, the former consisting of thin-walled berryllium tubes 58 filled with pellets 60 of uranium oxide and closed with compressed alumina plugs 62 and axial beryllium pins 64 which engage within apertures 66 in the corresponding grids, while the latter consist of thick-walled beryllium tubes 67 similarly filled and plugged. The tubes 67 are provided at their ends with threaded beryllium pins 78, 84 and threaded bores 80, 86 which are connected together through corresponding holes in grids 32, 34, while pins 74 on the lower set of tubes 67 are screwed into threaded holes in grid 28 and screws 90 connected to the upper grid 36 are threaded into the upper set of tubes 67.

Title: Improvements in or relating to photographic exposure meters
IPC: G01J1/42
Filed: 1952-11-20
Abstract: 748,083. Photo-electric exposure meter. SANGAMO WESTON, Ltd. Nov. 20, 1952 [Dec. 20, 1951], No. 29369/52. Class 40 (3). [Also in Group XX] A meter comprising a casing 10 having at one side a photo-cell 18 exposable to light through an aperture 17 in the casing and at the opposite side a moving coil electrical measuring unit (Fig. 1, not shown) having a pointer actuated in response to the photo-cell current, a scale for the pointer calibrated to read in one of the exposure factors consisting of camera diaphragm stop, film speed, and shutter speed, and a masking disc 28 pivotally mounted at 29 on the outside of the casing so as to vary the aperture of the photo-cell and calibrated in another of the exposure factors 30, said disc being rotatable with respect to a fixed set of marks 23, 24 representing the third exposure factor. As shown, the disc 28 may bear a scale of film speeds arranged so that for settings indicating increasing speeds the exposed area of the cell increases, the marks 23, 24 indicate shutter speeds, viz. 1/34 and 1/50 second, respectively, corresponding also to 16 and 24 frames per second, and the electrical meter scale is calibrated in diaphragm stops. Alternatively, the masking disc scale indicates exposure times and the fixed marks represent film speeds or the electrical metal scale may indicate shutter speeds and the masking disc scale may represent film speed or diaphragm stops. Preferably, the masking disc has an opening 31 overlaying the photo-cell when the disc covers a major portion of the aperture 17 so as to minimize the differences in response of different parts of the cell. The meter may carry a table showing the relationship between the exposure factor in which the electrical meter scale is calibrated and that indicated by either the scale on the masking disc or the fixed scale, the table preferably being visible in the window of the electrical meter. The member 22 carrying the fixed scale may be adjustable for calibration purposes, as may the zero setting screw 19 of the electrical meter.
Patent GB-243534-A (GB)
Title: An improved process and apparatus for carbonizing fuels
IPC: C10B53/02
Filed: 1924-12-08
Abstract: 243,534. Krauss, F. Dec. 8, 1924. No Patent granted (Sealing fee not paid). Coking processes; retorts.-In the distillation or gasification of peat, brown coal, and lignite, the hot gases from a central fuel chamber and produced therein or outside are passed into a second fuel chamber concentric to the first, and then, if desired, through one or more fuel chambers 'which surround both of the former chambers, and in which drying or carbonization takes place. An inner chamber 1 to which either hot furnace gases are supplied through a tube 4 or in which the fuel is burned in an air supply, is surrounded by an annular carbonizing chamber 2, which in turn is surrounded by a fuel drying chamber 3. Branches 4<a> from the pipe 4 lead the hot gases from the chamber 1 into contact with the fuel in chamber 2, the gases from which are circulated by a fan 6 and tubes 7 through the fuel in the drying chamber 3. The cooled gases escape through tube 8. Pipes 12, 13 lead off combustible gases for use in the chamber 1 or elsewhere. The fuel is charged into and the coke discharged separately from each chamber. The fuel in chamber 2 is heated both by heat from the wall of chamber 1 and by contact with hot gases. In modifications, the direction of the hot gases through the charge may be reversed, and openings may be formed in the wall of chamber 1 leading directly into chamber 2, chamber 1 being subdivided into several compartments, and conduits may be provided in chamber 2 to distribute the heating gases evenly through the charge. In Fig. 7 the hot gases are withdrawn by tubes 35, 36 and fan 6, and are heated in a coiled pipe 39 leading, according to the position of a valve 43, to chamber 2 or 3, or when a valve 44 is open, to the chamber 1. The fan 74, Fig. 12, withdrawing the gases may be controlled automatically by the heat of these gases, by providing in the outlet pipe 73 a valve 82 operated by a solenoid 81, the circuit of which and a battery 78 is closed when the contact element 80 in a thermometer 77 is reached, the valve being opened and air admitted through an opening 83, thus reducing the suction effect of the fan and cooling the outgoing gases. Liquid, such as water or hydrocarbons, from a tank 91, Fig. 14, may be vaporized in a coil 92 in chamber 1, and steam or oil vapour supplied through a, valve 95 either to the carbonizing or drying chamber or to a pipe 94 leading to a motor. The coke may be cooled by the gases leaving the apparatus. The hot gases may be generated by igniting and charring the fuel in the central chamber.

Title: Improvements relating to drop box looms
IPC: D03D43/00
Filed: 1925-11-24
Abstract: 266,442. Heyworth, E., and Pilling & Sons, Ltd., J. Nov. 24, 1925. Picking-motions.-In a drop-box loom, rods 1, one at each side of the loom, are provided with swell fingers 13 and elbow arms 2 having bowls 4 acting on curved arms 16 on the stop rod 15, which is thus operated from the swell fingers in the direction to move the usual fingers 17 out of their engaging position but not in the contrary direction. Each swell finger controls the picking motion at the opposite side of the loom, the elbow arms 2 having pin and slot connections to links 5 connected to arms on the picking catch pawl rods 7, 9, which are connected to the picking catch pawls. A control bar 20, which can oscillate and also move up and down and is guided by a slotted plate 25, is normally moved upwards and to the left by a spring 45, so that a shoulder 28 on 'the control bar engages under the plate 25. In this normal inoperative position, shown in Figs. 2 and 3, the control bar, which is indepedent of the usual starting handle, does not interfere with picking &c. When the weft fork lever is operated, the breast beam finger rod 32 is oscillated, and by means of a pin 30 on an arm 31 engaging a slot in the control bar disengages this bar 20 from the plate 25. The bar is then moved upwardly by the spring 45 into its operative position wherein pins 23, 24 act on fingers 18, 19 on the rods 7, 9 so as to disengage both picking catch pawls and stop the picking, whilst an arm 42 raises the swing finger 39 on the oscillating member 37 carrying the take-up pawl 38 out of the path of a projection on the lay sword 42, so as to stop the take up, but the movement of the lay is not interfered with. A flexible cord 33 disengages the pawl 36 of the dobby or jacquard, so that the loom can be run without the picking or take up motion or the jacquard or dobby being operated, whilst the weaver takes out broken picks. The weaver can afterwards depress the control bar to cause its shoulder to engage beneath the plate 35, so that picking &c. can recommence. The breast beam finger and rod can only move the control bar from its operative to its inoperative position, but this bar can be moved by hand into either position.
Patent GB-174194-A (GB)
Title: Improvements in starting internal-combustion engines
IPC: F01L13/00
Filed: 1920-10-20
Abstract: 174,194. Robinson, H. W., and Crude Oil Engines, Ltd. Oct. 20, 1920. Reversing; starting. - The start. ing and direction of running of a two- or four-stroke-cycle engine is controlled by a single handle, which moves in a slotted quadrant having a gate at one end, the movement of the handle in this gate determining the direction of rotation. The handle 21 when at its zero position in the quadrant 24 can slide along its pivot 22 and enter one or other of the slots 26, 27, Fig. 4, forming the gate; this movement turns one or other of the levers 40, 41 and through the vertical rods 48 and forks 44 slides the cam shaft 11 axially, in accordance with the desired direction of running. The handle is then rocked about its pivot and, through a bell-crank extension 36 and links 37, 39, raises a rack 30; this through the pinion 31 turns a lay shaft carrying a series of cams 51, Fig. 2, for each cylinder. These cams rock bellcranks 54 connected with tappets 13 between cams on the cam shaft and the engine valves and fuel pumps. The cams on the lay shaft are arranged to lift all the tappets, while the cam shaft 11 is being moved axially. For a four-cylinder engine there are also on the lay shaft two cams 33, Fig. 5, controlling main compressed-air supply valves 18, each valve serving two cylindem; the cambowl on the lever 34 has a spring trigger 46 so that if the lay shaft 12 is rotated in one direction the valve remains closed, but is opened when the shaft rotates in the other direction. The direction of rotation having been set the handle is moved to notch 1 in the quadrant; both valves 18 are opened; the compressed-air starting valves on the cylinders are brought into use and the fuel pumps and scavenging valves held out of action by the cams on the lay shaft. On moving into notch 2 one of the valves 18 closes, two cylinders work on compressed air and two fire, the fuel pumps and scavenging valves working. When in notch 3 the other valve 18 closes, all the starting valves are cut out, and all four cylinders work normally. To prevent wrong relative movement of the cam and lay shafts an interlock is provided in the form of two discs, one of which is notched to allow the other to pass by. For a four-stroke engine the cam shaft is also provided with cams for the exhaust valves. When the lay shaft lifts the tappets a link 62 holds open the fuel delivery valves of the pumps to prevent fuel supply; but fuel may be delivered by working the handle 64.

Title: Apparatus for and process of venting volatile mattter from viscous liquid
IPC: B29C48/92
Filed: 1974-07-04
Abstract: 1447716 Removing volatiles from extruded thermoplastics DU PONT OF CANADA Ltd 4 July 1974 [13 July 1973] 29762/74 Heading B1B [Also in Division B5] Volatile material from heat softened thermoplastics being extruded by a helical screw 23, is vented through a cylindrical tube 15 within which a screw flight rotates, both relative to the tube and to a shaft on which it is mounted, to return to the extruder any thermoplastics deposited in the tube or on the shaft. The outlet 18 of tube 15 may be connected to atmosphere either directly or via pressure control means, or to means for recovering the volatile material, and either or both the tube 15 and outlet 18 may have a heating or cooling jacket. The flight within the tube 15 may terminate at or beyond the inlet to tube 15, and the shaft of the flight may be stationary, or may also rotate either in a different direction to, or in the same direction as the flight but at a slower speed. The thermoplastics may be delivered to the location of the screw 23 at which venting occurs by further screws, or by a further part of the screw 23 or, as described, by gravity to the inlet of the screw 23, at a hopper 22 through the wall 21 of which the tube 15 extends into volatile matter accummulating at 26. The volatile material may comprise water in polyamide, or monomer, low molecular weight polymer, or solvent in thermoplastics obtained by polymerising unsaturated monomers in a solvent. The thermoplastics preferably comprises homopolymers of ethylene and copolymers of ethylene and higher olefins, containing up to 2.5% of volatile cyclohexane solvent, which is extruded through an underwater cutter to form pellets. The removal of the volatiles permits higher output, a more constant extrusion pressure to be obtained and a lower screw compression ratio to be employed e.g. 1:1, or preferably 2:1 to 2.4:1. The examples relate to the extrusion of homopolymers of ethylene, and co-polymers of ethylene and butene-1, polymerised in cyclohexane.

Title: Method of protecting mirrors
Inventor: GILARD PIERRE
IPC: C03C17/32
Filed: 1969-06-12
Abstract: 1291242 Protecting mirrors and mirror production INSTITUT NATIONAL DU VERRE 9 June 1970 [12 June 1969] 29888/69 Heading B2E At least one surface of a glass mirror is protected from soiling or damage by applying at least one coating composition to the surface which forms a protective film and which may be peeled from the glass when the protection is no longer required. The coating composition may be a solution of a film-forming vinyl polymer, e.g. polyvinylchloride which may or may not be chlorinated or a copolymer of vinyl acetate and a vinyl ester of a branch chain acid or it may consist of two or more ingredients which react in situ to form a film, for example a solution of a partially polymerized polyester and a hardener, e.g. cobalt naphthenate and a second solution of a partially polymerized polyester and an accelerator, for example cyclohexane peroxide, may be separately applied to the glass sheet. The polyester is preferably the reaction product of a polyhydric glycol and maleic acid. In a mirror production method in which glass sheets are passed in flat lying positions sequentially through metallisation and painting stations the bottom surface of each sheet is provided with a protective film before reaching the metallisation station. In an embodiment, glass sheet S is passed over roll 1 dipping in a bath 2 of the coating composition and then over a pipe 4 through which hot air is passing. In another embodiment the coating composition is pumped from a container 7 through a longitudinal slot 6 in a tube 5 placed just below the surface of moving glass sheet. The slot 6 may be defined by rollers or bars and may be adjusted. Excess coating composition falls back into the bath 7. The coating is dried by hot air from nozzles 11 and 12. The coated glass is then washed, silvered and coppered and painted on the other surface to form mirrors. The protective skin may then be removed.

Abstract: 1516752 Turning articles on a conveyer WHITIN MACHINE WORKS Inc 19 July 1976 [26 Sept 1975] 29970/76 Heading B8A [Also in Divisions Dl and D2] In the use of a combined doffing apparatus 11 (movable on rails 14) and bobbin supply and sorting apparatus 16 at a spinning frame 10, a box 18 containing a supply of empty-bobbins 20 is releasably secured in position by cooperating hooks 78 and pins 79. Buckets 27 of a conveyer 22 move through box 18 to collect bobbins 20 of random end orientation and elevate them in single succession under the restraint of sidewalls 86, 41 and skirts 88. At a detector assembly 47, each bobbin, the smaller end of which passes uninterruptedly between a bracket 50 and a lever 54 is carried therethrough and on to a delivery station 23 but each bobbin, the larger or butt end of which engages and enforces rotation of lever 54 carrying a tab 61 about a pin 52, is ejected by sudden rotation of a kicker arm 67 responsive to energization of a solenoid 66 caused by tab 61 interrupting the light beam of a photocell 63. The rejected bobbin directed into a return shoot 71, begins to fall therethrough, is arrested at one end by the arcuate surface of an inverter 96 to induce end-over-end rotation of the falling bobbin and, in consequence, reversed, i.e. corrected orientation as it contacts a face arresting inclined ledge 98 whence it rolls and drops into box 18 where it is again available for collection. Finger 101 of a limit switch 102 senses the state of bobbins assembled on a platform 32 ready for damming and includes de-energization or energization of a clutch 31 accordingly to stop or start the conveyer 22.
