Title: Improvements in and relating to thermoplastic films or sheets
Inventor: PATCHELL ALBERT GEORGE
IPC: B29C55/02
Filed: 1964-06-02
Abstract: 1,075,824. Stretching thermoplastic sheet. T. J. SMITH & NEPHEW Ltd. May 31, 1965 [June 2, 1964], No. 22812/64. Heading B5B. Sheets of thermoplastic material in continuous lengths are stretched transversely by the following method: at each side edge of the sheet an integral hollow loop is formed, closed at its outer edge portion, and held sealed at its inner edge portion; the loops pass on to, are held expanded by and move over suitably supported longitudinally extending fillers forming beaded edges, the sheet material passing through narrow gaps in fixed guides which diverge with respect to the central line; the material is drawn through the guides; and the exterior edges of the guides force the expanded beaded sides of the material apart laterally. The material may also be stretched longitudinally before, during, or after the transverse stretching. The loops may be formed by turning in the edge of the sheet to form an overlap and sealing the edge to the sheet (Figs. 1-3, not shown); or by superposing two sheets and sealing the outer edges (Figs. 4 and 5, not shown), or by using a flattened tube of material (Fig. 6, not shown), the guides acting to form the inner edges. The fillers may have one end free and located in the loop and one end supported at the beginning (Figs. 1 and 3) or end of the transverse stretching zone; in the latter case (Fig. 8, not shown) the loops may be cut to open them after the transverse stretching step to permit the passage of the fillers into the loops. Alternatively, the filler (Fig. 9, not shown) may have both ends free and be prevented from longitudinal movement by exterior means which hold the loop flat just beyond the two ends of the loop. The filler may be formed of polytetrafluoroethylene cords or a liquid or gas under pressure. The sheet may be open network, which may be produced from sheet material which is perforated or which is embossed on one or both surfaces with spaced bosses or raised figures.

Title: Improvements relating to pressure vessels
Inventor: CAMPBELL RONALD HUGH
IPC: G21C9/04
Filed: 1960-07-04
Abstract: 905,684. Reactor pressure vessels. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. July 4, 1961 [July 4, 1960], No. 23258/60. Class 39 (4). Fire suppression in a nuclear reactor is effected by the injection of a fire-suppressing fluid into the fuel channels through the piping system used to monitor the coolant to detect fuel element sheathing failure. The coolant from each channel passes through a detector and then into a common return duct from which it is pumped back into the pressure vessel. A valve 23, Fig. 2, is incorporated in the return duct and comprises an impervious membrane 24 in the form of a bursting disc and a perforated metal support backing 25 at the atmospheric side of 24. A small pressure differential acting from the atmospheric side, i.e. from left to right will fracture disc 24 while the disc, supported by the backing 25 resists the normal pressure within the reactor. If the pressure vessel is ruptured and a fall of internal pressure results, a fuel fire is prevented by the injection of borated water through valve 23 from the atmospheric side, the membrane 24 being broken by the low water pressure.

Title: Method of producing zinc sulphide pigment
IPC: C09C1/06
Filed: 1950-09-22
Abstract: In the production of a pigment, zinc sulphide obtained by precipitation from a zinc sulphate solution, preferably with hydrogen sulphide, after being washed, is allowed to stand for a prolonged period, say 48 hours, in 5-40 per cent sulphuric aci, or 1/10-1/1000 N hydrochloric acid, or in the absence of washing, in the acid reaction solution containing at least 5 per cent H2SO4, the ageing taking place advantageously at 80-150 DEG C and if desired or necessary at a pressure of up to 5 atmospheres gauge, and the precipitate is then washed, dried without calcination, and ground. The zinc sulphate solution used contains more than 40 and up to 100 grams/litre, and precipitation should, as far as possible, e quantitative, i.e. 96-97 per cent. If precipitation is not carried out to this extent, hydrogen sulphide is passed into the solution during the ageing, particularly when the sulphides, e.g. alkali metal sulphides, have been used initially.

The eccentric portion 8 is provided with a recess 15 to accommodate the gear 13 and bearing sleeves 18, 19 for the spindle 16. The ratio of the gearing 14, 13 is 3: 2 so that the rotor rotates one third of a revolution for each rotation of the shaft 7 (or the body if the shaft 7 is fixed). In a second embodiment, Fig. 3, the externally toothed gear 13<SP>1</SP> is formed integrally with a lip 22 of the end wall 2 so that the shaft 7 need not be hollow. The eccentric portion 8<SP>1</SP> is formed in two parts secured together by bolts 23 to provide a space to accommodate the internally toothed gear 14<SP>1</SP>. Bearings 26, 25 are provided for supporting the two parts of the eccentric portion on the lip 22 and another lip 21 of the end wall 1, respectively.

Specified cyclic nitrogen compounds are N-methane-sulphonyl-oxazolidine, N - p - toulene - sulphonyl - tetrahydro - 1,3 - oxazine, N - methane - sulphonyl - tetrahydro - 1,3 - oxazine, N - benzene - sulphonyl - oxazolidine, N - p - toluene - sulphonyl-4-methyl-oxazolidine and N-(C12- 18-alkane-sulphonyl-oxazolidine. A third comonomer, e.g. styrene, acrylonitrile, ethyl vinyl ether, methyl vinyl sulphone, ethylene or propylene oxide, cyclic acetals and their analogous thio compounds may be added as modifier.  The cationic active catalyst may be a concentrated mineral acid, a sulphonic acid, a Lewis acid, a boron halide etherate, a halogen containing organic aluminium compound, oxonium and carbonium salts and aryl diazonium compounds, while the polymerization may take place as bulk, suspension or solution. Examples are given of the copolymerization of trioxane in a saturated hydrocarbon fraction using, as catalyst, boron fluoride dibutyl etherate, with (1) N-benzene-sulphonyl-oxazolidine, (2) N-benzene-sulphonyl - tetrahydro - 1,3 - oxazine, (3) N - toluene-sulphonyl-oxazolidine and (4) N-toluene-sulphonyl -tetrahydro-oxazine.

Alternatively, 1,3-propanolamines containing a free amino group are reacted with sulphonic acid chlorides to form the N-(hydroxypropylene)-sulphonic acid amides which are then cyclised with aldehydes or ketones in the presence of acids of dissociation constant of at least 10-4 to give the oxazines.  The N - sulphonyl - 1 - oxa - 3 - aza - cycloheptanes (i.e. n=3 in above formula) may be obtained in a similar manner.
