Patent GB-1007407-A (GB)
Title: Stainless steel decladding
IPC: G21C19/38
Filed: 1964-03-16
Abstract: Stainless steel is removed from a stainless steel clad body by intimately contacting the body with a gaseous stream containing oxygen and solid metal fluoride particles.  In the preferred embodiment, a stainless steel clad body such as a stainless steel clad uranium bearing fuel element is immersed in a fluidized bed of which 1% by weight of the bed particles are aluminium fluoride and the remainder aluminium oxide.  The bed is activated by intimately contacting and fluidizing the bed particles with fluorine at a temperature between 400  DEG C. and 450  DEG C. for a period of up to half an hour, whereupon the bed is fluidized and the element immersed therein intimately contacted with oxygen at a temperature between 675 DEG C. and 750  DEG C. until the desired degree of decladding is achieved.  The steel cladding is often found to split, perforate or rupture during the decladding leaving the uranium exposed for immediate recovery.  Fluorine is then passed through the bed to intimately contact the exposed uranium and convert it into uranium hexafluoride which after being passed through filters is condensed and further treated by conventional means to recover the uranium therefrom. The bed is fluidized by fluorine in this latter stage under the same conditions as in the first stage so that the bed particles are again activated and the bed is ready to receive another fuel element for decladding.  In the preferred embodiment, the fluorine makes up 25% by volume of a mixture with argon, this mixture being used because of the high reactivity of fluorine, whereas the oxygen used is 100% pure.

Filed: 1967-03-06
Abstract: 1,114,148. Record retrieval. INTERNATIONAL BUSINESS MACHINES CORPORATION. 6 March, 1967 [28 March, 1966], No. 10383/67. Heading G4C. A position in a storage unit is addressed and a key field of the record in the addressed position is compared with a mask, the comparison being at least partly under control of a field of the record which specifies the length of the key field, a data field of the record being retrieved on equality. A computer selects a bulk storage module (magnetic discs, drums or tapes) using conventional channel controls by supplying its address, the module recognizing the address and sending its address to the computer for a check comparison. The computer selects a read-write head in the storage module and can perform an associative search on the records in the track thus selected, a serial by bit comparison being performed in the module for high, low or equal under control of the computer apprised of the progress of the search by status bytes transmitted from the module. Each record has three portions. The first portion identifies the disc surface, track and access mechanism (associative search may be done on these bytes) and specifies the lengths of the key and data fields. The second and third portions contain the key and data fields respectively. Associative search may be done on either of them. Particular bytes are skipped during this associative search if the bytes supplied by the computer at the corresponding times for comparison are special " skip " characters. Each portion also contains burst check bytes, an accumulating shift register being provided for checking purposes. Parity bits are also mentioned. A decrementable control counter, presettable from the length fields, is used to delineate the various record fields. Communication with the computer is serial by parallel byte, serial to parallel and parallel to serial conversion being performed as necessary. Ring counters are provided for gating purposes. Each track also starts with various identifying indicia.

Abstract: 232,974. Gerschel, A. April 26, 1924, [Convention date]. Cutting-edges, shaping and treating; guides and rests; wheels. -The blades of mowing, reaping, reaping and binding, and like machines, are sharpened by a grinding-wheel 26 which during sharpening is reciprocated in contact with the blade. The blade is held by clamps 15 secured to a channel-sectioned member 14, which is movable, on rollers 13, 17 on a bracket 11 secured to a plate 8. The plate 8 is mounted on a shaft 7 carried by a member 4, and by adjustment of the plate around the shaft 7 by means of screws 10, the blade may be positioned so that one edge of a mower blade section, or the adjacent edges of two sections can be sharpened. The member 4 is adjustable in a member 3 by a screw 5 and a nut 6 to move the blade towards or away from the grinding-wheel, and the member 3 is pivotally mounted on trunnions 2 in the frame 1 of the machine; screws 23 serve to adjust the position of the blade about the trunnions 2, and by means of a handle 24, the complete blade-holder may be lifted clear of the grinding wheel. In order to move the blade endwise to bring a fresh section into the grinding position, a bracket 18 is provided on the plate 8, and in the bracket is slidably mounted a rod 20 carrying a finger 22, which engages between two sections of the blade. An adjustable abutment 21 limits the endwise movement of the rod, so that by sliding the rod, the blade is moved the exact distance between sections. The grinding- wheel comprises an annular working part 26 with bevelled periphery held between cheeks 27 secured together by bolts 28 and spaced apart by a sleeve 29. Through the sleeve passes a hollow shaft 30 secured to the cheeks and to a shaft 32. The shaft 32 runs in slides 34 which are movable in guides 33 on a trough 25, and the grinding-wheel is reciprocated in the slides by a link 50 and crank 49 driven, through gearing 46, 47, from a shaft 36 carrying a driving crank 39. The grinding-wheel is driven, through a bevel pinion 35 on the shaft 32, by a bevel gear 44 mounted on a hollow shaft 41 carried by the shaft 36 and' rotated therewith by a pin 42 and a slot in the hollow shaft, or by a feather and keyway. The wheel 44 is kept in gear with the pinion 35 during sliding by the shaft 32, the end of which engages a groove 45 in the hub of the wheel 44. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a construction in which the bracket 18 and the abutment 21 are replaced by bosses cast with the plate 8, and a spring is provided for holding the finger 22 between two blade sections.

Filed: 1926-10-18
Abstract: 288,344. Miller, Inc., W. J., (Assignees of Miller, W. J.). Oct. 16, 1925, [Convention date]. Divided on 259,965. Blowing. - A device for coupling parts of a machine for making glassware comprises a detent yieldingly mounted on one of the parts to be coupled and adapted to engage in a recess in the other part, the detent maintaining a definite association of the parts under normal operating pressure but yielding gradually, and resiliently, under abnormal pressure and allowing the parts to uncouple. Fig. 1 shows the device applied to a rod 121 which rciprocates vertically in a sleeve 119 and carries at its upper end a plug 122 for forming the mouth ring. The rod carries at its lower end a roll 125 which engages in cam tracks 126 and raises or lowers the rod. A spring dog 127, disposed in a horizontal aperture in the rod 121, engages a notch in a bolt 128, depending from the frame 10 of the machine, when'the rod 121 is in its uppermost position. The rod is thus prevented from dropring by gravity and is held up until the roll 125 engages the proper cam track to lower the rod. When a charge of glass is dropped into the parison mould, compressed air is admitted above the glass from a blowhead 112 to compact the charge. The dog 127 prevents the plug from being depressed prematurely. Fig. 2 shows a blowhead 178 which is carried by a yoke 189 pivoted on a shaft 197, and it is swung about the shaft by a segment member 196, also pivoted on the shaft, which is moved by the vertical reciprocation of a rod 202. A latch 199, pivoted on the blowhead, is forced by a spring into engagement with a notch 200 on the segment, so that the blowhead and segment normally move as a unit. If the movement of the blowhead is obstructed, the latch 199 becomes disengaged from the notch and prevents breakage of the parts.

Abstract: 492,397. Cables ; extruding conductor casings. SOUTHERN UNITED TELEPHONE CABLES. Ltd., WHITEHOUSE, W. P., and MOORE, A. T. C. April 15, 1937, No. 10769. [Class 36] [Also in Group V] Air-space cables are manufactured by extruding insulating- material around a flexible mandrel which travels forwards with the extruded tube, treating the tube to harden it or to cause it to set, slitting the tube longitudinally, withdrawing the mandrel through the slit, opening the slit locally and progressively from one end of the tube feeding a wire into the tube through such opening and spacing the wire within the tube. Plastic material, such as polystyrol or the substance known under the Registered Trade Mark " Pernax," is supplied to an extrusion machine 1 through which passes an endless mandrel 2. The tube formed is reduced in diameter by drawing it forward, by means of the take-up drum 5, faster than it is delivered from the die, the mandrel 2 being somewhat smaller in diameter than the tube on extrusion : reduction in diameter is also caused by subjecting the interior of the tube adjacent the machine 1 to a partial vacuum. After extrusion, the tube is cooled or blown with air to cause hardening. The hardened tube is slit at 9 and the mandrel withdrawn through the slit. The tube is led from the drum 5 past an opening device 12 through which is fed a wire 10 having insulating discs or beads 11 fixed thereon. The tube is then fed intermittently to one or more constricting devices 14, each comprising a cylindrical casing 15 having circumferential slots 16 in which work tools 17. Fig. 7 shows the constriction produced by four such tools. Alternatively, spacing members 11 may be employed without constrictions, or constrictions without spacing members. An external covering may be formed on the tube by lapping, braiding and /or extrusion ; for instance, a tape of metal foil may be lapped on and such tape covered by an extruded tube of lead. Specification 24590/01, [Class 70], is referred to.
