Abstract: 1408298 Inner walls for cryogenic tanks BABCOCK & WILCOX Ltd 25 Aug 1972 [27 Aug 1971] 39639/72 Heading F4P The inner wall of a cryogenic tank comprises a plurality of metal plates 4, Fig. 10, each plate being spaced from the adjacent plates, every plate having intersecting corrugations 6, 7 such that the corrugations of the plates are aligned with one another, and each gap between a pair of adjacent plates being bridged by strips 28, 30 which are welded to the two plates and have transverse corrugations which interfit with corresponding corrugations on the plates. Caps 33, Fig. 11, are welded over the gaps left at the corners of the plates, the caps being shaped so as to have portions 35 which fit against the plate corners with intermediate portions 34 for lifting over the ends of the strips 28, 30. In assembling the inner wall, each panel is supported on a base of thermal insulation by a pair of pegs 16, Fig. 3, which extend through a respective pair of openings 5 in the plate. Each peg 16 has a pair of rotatable pins 19, 23, each of which has an eccentric portion 21, 25 which extends through a respective slot 22, 26 in respective horizontally and vertically movable blocks 17, 18. Looking at the horizontally movable block 17, it can be seen that rotation of pin 19 causes the desired horizontal movement. Vertical movement of block 18 is similarly effected. The pins 19, 23 are suitably adjusted in both pegs so that the respective plate is corretly positioned. From Fig. 5 it can be seen that after the required vertical movements have been made with the top of each opening resting on its respective block 18, Fig. 5A, then the left hand block 17 the plate 4 to the left to the required position, Fig. 5B, after which the right-hand block 17 is moved rightwards to engage its opening so that the blocks 17 between them prevent lateral movement of the plate. When all the plates are positioned they are welded to backing strips 10, 11 to maintain the required relative position whilst the bridging strips 28, 30 are attached. The caps 33 are finally welded into position. A cover 36 is welded over each hole 5 and is either cup-shaped to accommodate the projecting peg or is in the form of a flat disc if the pegs are removable. In an alternative embodiment (Figs. 14 to 16, not shown), specially suitable for large plates 4 with a high flexibility, a larger number of adjustable supporting pegs 16 may be provided, these being supplemented by a plurality of attachment means for fixing the plate at multiple points on its surface to the insulation after the necessary adjustment is made.

Abstract: 1379138 Controlling gas burners CONTROLS CO OF AMERICA 16 Aug 1973 [31 Aug 1972] 40392/72 Heading F4T [Also in Divisions F2] A gas flow control device, e.g. for a gas fired space heater, having an inlet 11 and outlet 40, Fig. 1, includes a thermostatic valve control mechanism comprising a lever 25 pivoted at 26 and bearing at one end on an actuating rod 28 controlling coaxial snap-action low flow valve 30 and main valve 31, Fig. 2. The valves 30, 31 comprise a piston 32 slidable within cylinder 33 to which gas is led via a aperture (34, Fig. 5, not shown), in the cylinder wall, passage 55, pressure regulator 29 and safety valve 14. The crown of piston 32 contains apertures 35 for the low flow valve 30 having a closure member 36 biased to the closed position by spring 49 acting on a stem 46, attached at its lower end to disc 44 which snaps member 36 open when spoked member 47 is urged upwardly by actuating rod 28. A low flow then passes downwardly through piston 32 and apertures 41b in a guide member 41 for rod 28. Further movement of the latter urges piston 32 upwardly against spring 54 causing flexible sealing ring 52 of main valve 31 to deform from a flat to a dished shape as the piston moves away from seat 51. Initially the periphery of ring 52 remains against seat 51 and main flow takes place through apertures 52a in the ring and thence through apertures 41d in parallel with low flow apertures 41b. Further movement of piston 32 causes ring 52 to lift-off seat 51 to increase the main flow. The control device also includes a manual knob 12 movable axially to close an interrupter valve 13 and open safety valve 14 to allow gas to flow to a pilot outlet 15, and an electromagnetic safety device 16 energized by a thermocouple 17 when a pilot flame 18 is present. An interlock device 20 is operable after closure of safety valve 14 to prevent reopening of the latter before the main burner has cooled. Rotation of knob 12 adjusts a temperature setting cam 21 bearing on one end of a lever 22, the other end of which presses on the upper end of thermostat bellows 23. The interior of the latter is pressurized with fluid from a temperature sensing bulb (24, Fig. 5, not shown). The lower end of bellows 23 acts on one end of the valve actuating lever 25.

Title: Material containing aluminium halide and lower halide of titanium
Inventor: STANLEY ROBERT HOLROYD
IPC: C01G23/00
Filed: 1961-11-13
Abstract: Unsaturated hydrocarbons, e.g. ethylene and propylene, are polymerized in the presence of a Ziegler/NaHa catalyst containing aluminium halide and a lower halide of titanium; this halide material is made by reaction between aluminium and titanium tetrahalide in the presence of free halogen (see Division C1). The catalyst also contains an organo-metallic compound, e.g. metal alkyl or aryl or metal alkyl halide, the metal being of groups I-III of the Periodic Table, e.g. A1.ALSO:Material containing aluminium halide and a lower halide of titanium is made by reducing a titanium tetrahalide with aluminium in the presence of free halogen.  The stoichiometric ratio of titanium tetrahalide to aluminium is at least unity; 1-50 moles halogen per 100 moles titanium tetrahalide are employed.  Liquid diluent, e.g. aromatic hydrocarbons or chlorinated hydrocarbons, may be present, or excess of titanium tetrahlide, if liquid, may be used as reaction medium.  The reaction, which commences at ambient temperature, is performed under reflux, preferably in an inert atmosphere, e.g. Ar or N2.  A slurry is obtained, from which a solid is recovered, e.g. by filtration or distillation. The halogen, preferably sufficient only to initiate the reaction, may be added to the liquid before or after the aluminium. Further liquid may be added after the initial reaction.  The aluminium is preferably finely divided:  e.g. 0.5 m  diameter particles.  The material may be used as a nucleating agent in vapour phase oxidation of TiCl4 to form TiO2. For use as Ziegler/Natta catalyst, the dry product may be milled either dry or in liquid vehicle, e.g. the polymerization medium (see Division C3).
