Title: Improvements in nuclear reactors and in nuclear reactor fuel elements
IPC: G21D5/08
Filed: 1962-04-22
Abstract: 1,018,481. Reactors; fuel elements. BABCOCK & WILCOX CO. Aug. 22, 1962 [Aug. 23, 1961], No. 32222/62. Heading G6C. A nuclear reactor has fuel elements formed of clusters of cylindrical fuel cans, some of the elements being provided with retaining means to prevent their displacement by coolant flow, the retained fuel elements themselves retaining adjacent fuel elements not possessing said retaining means. The retaining fuel elements, Fig. 5, include grapples 104 which engage lugs on the under face of the lower grid plate 60 (Fig. 1), and can be released by means of a rod 108 actuated from above the fuel element to withdraw the locking wedge 112. Adjacent fuel elements are retained by springs 126 mounted on the top casting 88 of the fuel element, and also by lugs mounted at the lower ends of said adjacent fuel elements which engage beneath the shoulder formed by the cylindrical body portion 94 of the retaining fuel element. Dowels are provided for lateral constraint. The reactor is adapted to operate with spectral shift control as described in Specification 894,902, and uses a combined moderator and coolant in the form of a mixture of light and heavy water. The pressure vessel 54, Fig. 1, is supported on a base 200 during construction, but on completion its weight is supported by a cylindrical biological shield 196 which is waterfilled. The moderator-coolant enters through a pipe 17 and passes downward, cooling the thermal shields 140, 150, 152, into a lower plenum chamber 62, from which it flows up through the core to an upper plenum chamber 66 and out of the reactor through a pipe 18. The upper plenum chamber includes a filler casting 178 to reduce the required volume of moderatorcoolant. Top mounted control rods 12 are used for emergency shut-down, and a portion of the coolant is allowed to leak through the controlrod guide tubes 158 into the uppermost part of the pressure vessel. The lattice (Fig. 2, not shown), is arranged so that each retaining fuel element is surrounded by four retained fuel elements having within them cruciform control rod passages. Fuel elements (Fig. 5).-The individual fuel cans are retained in each element by top and bottom grip plates 78, 80 and an intermediate grid 82. The fuel cans 84 at the corners and 86 at the side mid-points are made of thicker section tubing and constitute structural members for connecting the top and bottom fuel element grid plates. Similar tubes are used in the same manner in the control rod-passage-containing fuel elements. The structural cans are threaded for retention in the upper grid plate.

Title: A new or improved detachable wheel for motor cycles and the like
IPC: B62K25/02
Filed: 1935-11-22
Abstract: 460,733. Detachable wheel mountings for motor-cycles &c. NORTON MOTORS, Ltd., and FRANKS, E. M. Nov. 22, 1935, Nos. 32354/35 and 15154/36. [Class 136 (ii)] In a readily detachable wheel mounting for motor-cycles &c. adapted to be manipulated without the use of tools, the wheel hub 1 is detachably secured to a brake-drum or chain-wheel or to a combined brake-drum and chain-wheel 13 by studs 22 which are parallel to the axis of the wheel and are screwed into the drum 13 or chain-wheel, and the studs 22 after being tightened by the fingers are further tightened and locked by partial rotation of a disc 20 having arcuate slots 21, Fig. 2, through which the studs pass and having adjacent to the slots inclined or cam surfaces which, on angular movement of the disc, wedge between the heads of the studs 22 and the hub shell on the ends of spacing-sleeves 23 through which the studs pass. The spindle 4 passes through a sleeve 3 and screws into a sleeve 7, which is rigidly held in one side 8 of the fork by a nut 9 and carries the stationary back-plate 10 of the brake, the drum 13 of which is rotatably mounted on the sleeve 7 but retained thereon by means of annular shoulders 15, 16. A sleeve 19 is slidably keyed on the spindle 4 on the inside of the fork side 6, and is provided with an arm 30 carrying a spring-pressed peg 31 adapted to be pressed by the fingers into engagement with a recess 32 in a lug on the cam disc 20, which is thus keyed to the stationary spindle 4, whereby partial rotation of the wheel causes relative angular movement of the disc to lock or unlock the studs 22. After unlocking, further rotation of the wheel rotates the spindle 4 and unscrews it from the sleeve 7, thus slackening the grip of the fork sides and allowing, after removal of the studs 22 by the fingers, the wheel and spindle to drop out of the fork, leaving the brake-drum and chain-wheel in position on the fixed sleeve 7.

Title: Improvements in and relating to plant for oiling or moistening textile fibres and the like
Inventor: SCHLUMBERGER ROGER
IPC: D06B1/02
Filed: 1952-12-22
Abstract: Plant for oiling cotton or other textile fibres comprises an oil tank, an air-compressor and an atomizer which has an oil inlet and three separately controlled pipe lines for admitting air under pres <PICT:0708520/IV(c)/1> <PICT:0708520/IV(c)/2> <PICT:0708520/IV(c)/3> <PICT:0708520/IV(c)/4> sure so that a sheet like dispersal of the atomized oil jet is produced.  Fig. 1 shows a cotton oiling plant in which oil from a tank 2 is pumped into a tank 4 and is fed into two constant level tanks 7a, 7b.  Compressed air from a compressor 11 is fed to atomizers 8a-8d to which oil is fed from tanks 7a, 7b controlled by panels 13a, 13b respectively so that a sheet-like dispersal of the atomized oil jets from atomizers 8a-8d is produced and is applied to two cotton laps 9a, 9b which pass over beaters 10a, 10b respectively.  The oil level in the constant level tanks 7a, 7b can be adjusted so that it is located at, above or below the atomizers.  The compressed air supply line 12a divides into three branches.  Fig. 2 (not shown) in each of which is located a regulating sluice valve and measuring appliances.  In two of the lines are located electrically operated valves which are synchronized with the device which advances the corresponding lap of cotton so that in the event of the lap stopping the air supply is cut off and the spray ceases.  Figs. 4 and 5 shows the construction of an atomizer which ensures a sheet-like dispersal of the oil jet 42, Fig. 3.  Oil is admitted from the constant level tank (Fig. 1) into the oil chamber 24 and the compressed air pipes are connected at 19c, 20c and 21c respectively, so that when pressure is applied at inlet 20c piston 32 and rod 29 are depressed against the action of spring 31 to displace joint 30 from its seating 27 and admit oil from chamber 24 into the oil outlet duct 28.  The air connection 21c effects atomization of the oil leaving outlet 28 in known manner, the system comprising an annular chamber 34 communicating with two helical passages 35, 36 of opposite pitch which terminate in two atomization pipes 37, 38. Air inlet 19c communicates with an annular chamber 39 from which two inclined blast pipes 40, 41 start which are arranged symmetrically on each side of the oil outlet duct 28 so as to spread out the atomized oil into a sheet as shown in Fig. 3, the breadth of which can be adjusted by variation of the air pressure in the line feeding inlet 19c.

Title: Improvements in or relating to retorts and furnaces
IPC: C10B7/02
Filed: 1921-12-03
Abstract: 196,958. Bonnard, L. H. Dec. 3, 1921. Retort furnaces; discharging; cooling discharged materials.-In a mechanical furnace or retort for the treatment of mobile materials such as sludge, ores, sawdust, and decolourizing-carbon, having a number of superposed trays or hearths over which the materials are moved bv rabble blades, arrangements are provided for raising and lowering the blades so that they act alternately to spread the material and to move it over the travs. The blades 17 are mounted on a rotary shaft'16, which is driven through gearing 21, 22, and is raised and lowered by the engagement of rollers 19 with a fixed face cam 20. The pressure on the cam is reduced by counterbalancing the shaft by means, of a weight 26. When the blades are lowered to contact with the trays more than once in each revolution, the number of blades for each tray should be incommensurable with the number of times of contact. The material is fed from a hopper 27 on to a plate 29 and is swept through a drop opening therein by an arm 31 on the shaft The retort is heated by tangentially arranged burners 4, and the material is discharged by a screw 8 into a sealed receiver 12 connected to the conveyer casing by an expansion pipe 11. The material is cooled by a water jacket 9 around the conveyer casing. Specifications 11174/13 and 118,960, [Class 55 (i), Coking &c.], are referred to.

Title: Improvements in or relating to a process for making polypropylene film
IPC: B29C55/14
Filed: 1961-09-12
Abstract: Biaxially oriented film of stereo-regular polypropylene is produced by extruding a molten flat film of the polymer through a slot die at a temperature below 290 DEG C., quenching the film to a temperature below 40 DEG C., rapidly reheating the film to 110 DEG  to 160 DEG C. by contact for a period of less than 3,5 seconds with a heated rotating roll, stretching the film to 1,2 to 3 times its length as it leaves the roll, quenching the film to a temperature of less than 40 DEG C. within 2,5 seconds after it leaves the roll and subsequently stretching the film transversely at 95 DEG  to 160 DEG C.  The film may be quenched initially by contact with a cold rotating roll. After transversely stretching the film it may be restretched linearly to induce additional linear orientation.  In an example, stereoregular polypropylene having a birefringent melting point of about 170 DEG C. and a reduced specific viscosity (the ratio of the absolute viscosity of a 0,1% solution of the polymer in decahydronaphthalene at 135 DEG C., to the absolute viscosity of the solvent at 135 DEG C.) of about 2,8 is extruded at 232 DEG C. through a slot die at a rate of about 3 ft./min.  The molten film is cast on to a rotating roll having a surface temperature of 21 DEG C. and a peripheral speed of 12,4 ft./min. and then travels to a roll having a surface temperature of 121 DEG C. and a peripheral speed of 12,4 ft./min.  The film, after remaining in contact with the heated roll for 3,33 seconds, travels to a third roll having a surface temperature of 21 DEG C. and a peripheral speed of 20,6 ft./min. From the third roll the film, now linearly oriented, travels via further rolls to an enclosed tenter chamber through which it is passed at a speed of 22 ft./min. and in the first 50 inch length of the chamber is heated to 43 DEG C. without being transversely stretched.  In the second 50 inch length of the chamber the film is heated to 168 DEG C. and stretched transversely by means of conventional tenter clips to a width 1,47 times its original width. In the third 50 inch section of the chamber the film is allowed to cool to 49 DEG C. without further stretching and upon leaving the chamber is edge-trimmed and wound. The production of the film in the prescribed manner enables the transverse stretching step to be effected without loss of clarity of the film or its linear orientation.

Title: Improvements in or relating to coal-cutter picks
Inventor: SHEPHERD-SMITH STEPHEN
IPC: E21C35/19
Filed: 1961-09-13
Abstract: 939,370. Mineral-mining picks. AUSTIN HOY & CO. Ltd. Sept. 13, 1962 [Sept. 13, 1961], No. 32906/61. Class 68 (1). Mounted within the shank 12 of a coal cutter pick 11 is an outwardly biased latch 25 for engaging within a recess 20 in the wall of the socket 44 of a pick-box to lock the pick in the box when the pick is inserted in the socket, and within the recess 20 is a spring-loaded plunger 30 that when urged through the recess 20 towards the socket clears the latch from the recess 20 so that the pick can be withdrawn from the socket. Outward biasing of the latch 25 is due to a rod 27, on engaging an inclined surface 18 at the bottom of the socket 44, causing compression of the cylindrical resilient sponge block 26 that is bonded to the rod 27 and the latch 25. Movement of the plunger 30 down through the recess 25 is due to a projection 36 on a downwardly swung lever 34 having a boss 35 that can be fulcrumed in a semi-circular notch 33 in the leading face of the pick.
