Patent GB-963791-A (GB)
Title: Nuclear reactors
Inventor: DODD JOHN ALAN
IPC: G21C7/26
Filed: 1962-01-11
Abstract: 963,791. Nuclear reactors. SOC. ANGLOBELGE VULCAIN S.A. Dec. 10, 1962 [Jan. 11, 1962], No. 1047/62. Heading G6C. A nuclear reactor core comprises a central stationary fuel unit 11 assembled as a neutron multiplying region and surrounded by a plurality of rotary fuel units 12-17 having three sectors 18, 21, 19 assembled respectively as neutron multiplying, neutron moderating and neutron absorbing regions and being rotatable to afford control of the core reactivity. The fuel units 11-17 are in the form of cylindrical drums with the central drum 11 containing enriched uranium aggregated in rod form and assembled together with graphite according to a uniformly spaced lattice configuration or systematically repeating pattern so as to have an infinite multiplication factor greater than unity. Coolant fluid is circulated through the lattice. Similarly the sectors 18 of the fuel drums 12-17 are assembled as neutron multiplying regions while the sectors 19, 21 are assembled from boron-containing material and graphite, respectively, so as to constitute neutron absorbing and moderating regions. A stationary reflector 22, e.g. of graphite bricks, embraces the core and fills the outer interstitial spaces between the drums. Alternatively, fertile material such as natural or depleted uranium can be used to fill these spaces. The inner interstitial spaces afford location for the insertion of further neutron moderating material, or conventional control rods 23 for supplementary control. Initially, the neutron absorbing sectors 19 are positioned adjacent the central drum 11 and the core is subcritical. Criticality is brought about by rotating the drums 12-17 clockwise to move the multiplying sectors 18 inwards towards the central drum 11 to the position shown. In this initial critical state the core is under-moderated and criticality is accompanied by absorption of excess neutrons in fertile material in the core to convert this material into fissile material. As the core is burnt up the initial excess reactivity of the core is reduced and criticality of the core is maintained by further clockwise rotation of the drums 12-17 so that the moderating sectors 21 are gradually moved inwards towards the central drum 11. Modifications to the above include the use of peripheral arcuate sectors for the different regions of the fuel units and the use of a star-shaped central unit with the encircling drums rotating between the arms of the star. The invention is described as having particular advantages for marine propulsion. Specification 922,498 is referred to.

Filed: 1951-11-06
Abstract: 743,520. Glass manufacture. BECTON DICKINSON & CO. Nov. 6, 1951, No. 1237/55. Divided out of 743,477. Class 56. A mandrel 15 on which glass tubular blanks are shrunk to acquire the accurately sized and finished bores. required for hypodermic syringes, has axial and radial passageways 16, 33, 35 so that vacuum may, be applied to the space between the blank and the mandrel to collapse the softened glass on to the mandrel. The mandrels 15 are spaced around a turntable 11 which is indexed from station to station, the bottom ends 17 of the mandrels being tapered to wedge in sockets at the upper ends of hollow shafts 19 which are rotated by radial shafts 30 and gear wheels 28, 29 and are connected to vacuum at 25. The blank 39 rests upon a collar 35 supported by a spring 37 from a shoulder 38 on the mandrel, the spring maintaining the top of the blank spaced from the top of the mandrel until the vacuum pulls it down. Heating is effected by burners 44 on a segment 12 which oscillates so that the burner follows the mandrel from one station to the next, and then returns to heat the next blank, the blank abandoned by this burner being heated by the next burner on the segment, and so on. The mandrel passes through several heating stations, and a station where the tip 42 is melted and sealed, before the vacuum is applied through the axial bore 16, radial passages 35 and top grooves 33. The burner at the vacuumapplication station is traversed upwardly along the blank to compel the blank to shrink on to the mandrel, first at the bottom and then progressively towards the top. The blank is then allowed to remain on the mandrel for a cooling period, the different coefficients of expansion freeing it from the mandrel for removal therefrom. In Fig. 6, the blank 93 rests upon a shoulder 99 of the mandrel 96, and has an open top which is plugged by a valve-like member 103 having a centering spill 105 which is received in the axial bore 97 of the manydrel. Heat is applied by burners 100. and the burner at the shrinking station heats the whole length of the blank without traversing. When vacuum is applied, the blank is shrunk on to the mandrel and the valve member 103 beds into the upper end of the blank. The zone 34 at the base of the mandrel may be very slightly flared, i.e., the zone may be about one-eighth to three-sixteenths of an inch long and the taper may be about one-thousandth of an inch.

Title: Improvements in or relating to the steam-treatment of textile fabrics
IPC: D06C7/00
Filed: 1953-01-21
Abstract: <PICT:0735947/IV (c)/1> A method of steam-treating a roll of fabric comprises injecting steam into a tank containing the fabric mounted on a perforated roller to effect pre-heating and subsequently injecting steam through the fabric from the interior of the roller. The Figure shows an apparatus for stabilizing textile fabrics comprising a cylindrical tank 10 having a steam jacket 11 in which is accommodated a roll of fabric 12 mounted on a perforated roller 13. The roller is provided internally with tubular members 14 which are positioned inside the roller to coincide with the perforations in it so that a considerable amount of condensate can then be accommodated. The roller 13 is mounted at an angle on a framework 15 which is run into the tank 10 via a door 16 by means of rails 18 and wheels 19, the steam inlet pipe 30 and outlet pipe 32 then being connected by means of quick-release joints 31, 33. The shaft 25 of roller 13 is connected to the steam inlet pipe 29 via a tapered union 25, 28 which is held firmly closed by adjustment of bolt 27.  When the roll of fabric 12 is in position air is withdrawn from the tank 10 by a vacuum pump attached to sleeve 36 until a pressure of some 5 inches of mercury is obtained.  Steam is then injected into the tank through pipe 35 to pre-heat the contents of the tank until the pressure inside is about 1 lb./sq. inch above atmospheric.  The steam supply to pipe 35 is then cut-off and steam supplied via pipe 29 to the interior of roller 13 any condensate draining away continuously through roller outlet pipe 32 or down the sloping base of tank 10 through the tank outlet pipe 34.  When the process has been completed the steam supply to pipe 29 is discontinued, the pressure release valve 37 is opened, and the fabric removed.
