In the pool of a swimming pool reactor, fuel elements are individually inspected by means of X-rays. The element is mounted in a pressure tube, through which gas is circulated, and scanned by an X-ray beam, the image being viewed either by a photographic or a television camera. The X-ray tube, photographic camera and television camera, are mounted in a watertight container which is movable along and around the pressure tube. Water is displaced away from the X-ray beam by means of inflatable chambers surrounding the pressure tube. Protection against gamma radiation is provided for the photographic camera by a shield and for the television camera by a mirror system interposed in front of the lens.

Filed: 1925-07-11
Abstract: 263,952. Taylor, A. M. July 11, 1925. Addition to 232,275. Drawings to Specfication. Transmission conductor arrangements.- In a transmission system according to the parent Specification employing intersheath cables and an overhead line in conjunction, the voltage of the latter is raised considerably above that of the principal core in the cable by using transformers. The overhead line may transmit load currents as well as the charging current for the core and intersheaths and overhead 'and underground systems may run parallel so that each may act as a standby to the other. The engaging currents of inductive loads concentrated at the principal substations are employed to furnish the energy for cable charging over such lengths of cable as will give resonance with the full load of the substation. An extra-high tension overhead line 220,000 volts three phase may be connected at intervals with underground 150,000 volt three-phase mains by small transformers in " dummy " substations arranged to step up or down the voltage of the charging currents for the principal cores and also to supply currents at appropriate voltages to the intersheaths. At the main substations the stepdown transformers perform similar functions. Inductances may be used in series with the secondaries connected to the intersheaths.

Title: Esters of dibasic carboxylic acids and their use as lubricating oils
IPC: C07C69/34
Filed: 1965-04-28
Abstract: Lubricants comprise at least one diester of an alkyl succinic acid of the formula <FORM:1099716/C4-C5/1> where R3 is a C4- 10 alkyl group and R1 and R2 are the same or different and represent C6- 10 alkyl groups.  Specified esters are the di-n-octyl esters of iso-octyl- and iso-butyl-succinic acids, di-(2-ethylhexyl) iso-octylsuccinate and n-hexyl n-octyl iso-octylsuccinate.  The lubricant may include other esters, e.g. those of the above formula in which R3 is a C4- 10 alkenyl group, esters derived from trihydric aliphatic alcohols and long chain monocarboxylic acids, such as trimethylolpropane tripelargonate, and esters derived from C6- 10 aliphatic dicarboxylic acids and monohydric C8- 10 aliphatic alcohols.  The lubricants are particularly useful for high speed engines, e.g. jet engines and gas turbines.ALSO:The invention comprises di-n-octyl isooctylsuccinate, di(2-ethylhexyl) isooctylsuccinate and n-hexyl n-octyl isooctylsuccinate.  The compounds are prepared by esterification of the corresponding succinic acids or anhydrides with the appropriate alcohols, preferably in the presence of p-toluene sulphonic acid. The diesters are used as lubricants (see Division C5). The n-octyl diester of isobutyl succinic acid are prepared in a similar manner. The iso-octyl- and isobutyl-succinic acid anhydrides reactants are prepared by reduction of the corresponding isooctenyl- and isobutenyl compounds, e.g. by hydrogenation over a Raney Ni catalyst. Isooctenyl succinic anhydride is prepared from maleic anhydride and di-isobutylene.

Title: Improvements in and relating to machines for making tires
IPC: B29D30/10
Filed: 1918-10-14
Abstract: 145,679. Goodyear Tire & Rubber Co., (Assignees of Harsel, W. B., and Nall, E .A.). Nov. 3, 1917, [Convention date]. Tyres, elastic, special apparatus for making.- Relates to a machine of the kind described in Specifications 120,563 and 120,564 for building-up the fabric foundation of a tyre cover. The present Invention comprises means for rotating the mandrel (2) at high or low speed and for stopping same in any position or after a predetermined portion of a revolution. To provide for rotating the mandrel-shaft 13 at variable speeds, the latter carries gears 16, 17 in mesh with gears 37, 36 on the countershafts 31, 30 respectively. Each of these shafts is in two parts connected by magnetic clutches 39, 38. To stop the shaft 13 at any instant, each clutch is fitted with a band-brake 225 the ends of which are connected to a weighted lever 226 tending normally to apply the brake. The free end of each lever is supported by the core of a solenoid 227 (in the corresponding clutchcircuit) and is raised, when the core is energized, to release the brake. To prevent shocks, a friction-drive is fitted between the sprocket 36 and shaft 30 of the high-speed gear. To facilitate the application of a single ply of fabric, means (see Figs. 6 and 7) are provided for transmitting one revolution to the mandrel comprising, a solenoidclutch, the solenoid 232 being carried by the end of the mandrel-shaft 13, and the disk 233 by a boss 235 on a co-axial shaft 234. The solenoid is in the circuit of the low-speed shaft-controls 39, 227 which also includes a make-and-break 241, 245. The latter is opened after one revolution of the shaft 13 by the engagement of an adjustable stop 248 on the disk 233 with a trip-arm 244 on the spindle of the switch-tinker 245. The circuit being thus broken, the disk 233 is reversed' by the spring 238 unwinding the band 236, and is stopped by the abutment of a projection 249 with a fixed bracket 250. In a modification of the driving- gear, the countershafts 30, 31 are omitted, the mandrel-shaft being alined with the main (variable-speed) driving-shaft and adapted to be operated through a solenoid-clutch with electricallycontrolled stop-mechanism similar to the brake 225. A treadle-operated switch is provided for freeing the mandrel for hand-rotation.

Abstract: 1,148,839. Pneumatic conveyers. BROWN & WILLIAMSON TOBACCO CORP. 19 April, 1967 [3 May, 1966], No. 18094/67. Heading B8A. A pneumatic conveying system for automatically conveying tobacco from a feeder 10 to any one of a plurality of cigarette-making machines 12a-12j when the tobacco supply at the one machine falls below a pre-determined level, comprises a feed pipe 14 between the feeder 10 and the machines, a suction blower 20 forcing air through the pipe at a predetermined conveying velocity, and a differential pressure switch 18 in the pipe 14 to control the operation of the feeder. A separator 13a-13j associated with each machine 12a- 12j comprises an inlet controlled by a check valve 30a, an outlet having a solenoid operated suction control valve 32a and a screen between the inlet and outlet to separate the tobacco from the conveying air. With an appropriate drop in tobacco level in a machine hopper below the associated separator, a sensing switch 66 is operated to energize an electric circuit which causes the valve 32a to be opened, whereupon the suction then applied to the separator opens the check valve 30a and closes a flap in the base of the separator. Tobacco accumulating on the flap eventually blocks the separating screen and a switch 72 actuated by a pressure differential across the screen operates to de-energize the electric circuit, whereupon the suction and check valves 32a, 30a close and the flap opens to discharge the tobacco to the machine. A time delay switch is energized with energization of the electric circuit, and deenergizes the circuit after a time nterval to prevent overloading of the separator 13a if the pressure differential switch 72 has not been operated during this time interval. The feeder 10 comprises a feed belt which delivers tobacco to a metering belt upon a low level on the metering belt being sensed. A doffer above the metering belt meters the tobacco fed into the pipe 14. A controlled air bleed 34 in the feed pipe 14 adjacent the machine 13d furthest from the feeder 10, allows air to bleed into the system when any of the other machines are being fed, to provide a two directional supply of air into the machine being fed. A dust separator 24 and air bleed 26 are provided adjacent and upstream of the blower 20. A second feeder 10<SP>1</SP> supplying a different brand of tobacco can be coupled into the system to supply any of the machines disconnected from the feeder 10.
