Abstract: 1,004,802. Turbines; centrifugal pumps. P. J. J. DU PREEZ. Dec. 10, 1963 [Dec. 13, 1962; May 11, 1963], No. 48674/63. Headings FIC and FIT. A radial inward flow turbine has an accelerating system for directing fluid flow on to the turbine rotor through a zone between the system and the rotor and includes means for bleeding off working fluid from the zone at a predetermined pressure, the rate of bleed-off being responsive to pressure in the zone. A radial inward flow turbine 10, Fig. 2, has an inlet volute 22 supplying working fluid through optional guide vanes 26 to a turbine rotor 60a discharging through opening 32. A second volute 38 communicates with a zone 28 between guide vanes 26 and the periphery of turbine rotor 60a. An impeller 60b integral with turbine rotor 60a serves to bleed off working fluid from the zone 28. The bled fluid is either returned through a diverging pipe, Fig. 4 (not shown), to the turbine inlet pipe, or in the case of a liquid is pumped by impeller 60b through an outlet pipe 40, Fig. 3, at a pressure higher or lower, depending on the diameter of the impeller, than that at inlet 44. A control valve 45 is provided in each case. Fig. 5 (not shown) illustrates the mounting of the impeller blades on turbine rotor 60a. In a modification, Fig. 1 (not shown), impeller 60b is dispensed with and volute 38 communicates directly with zone 28. In this case pipe 40 acts as a stand pipe with an outlet 42 at a given height above the inlet 44. Alternatively a pressure relief valve 46 may be provided. The constructions are said to maintain the pressure in zone 28 substantially constant with variation in load on the turbine shaft 18 so as to maintain the shaft speed constant.

Abstract: 1,122,999. Caps for bottles. METAL BOX CO. Ltd. 11 Aug., 1966 [19 Nov., 1965], No. 49339/65. Heading B8T. A venting cap and bottle neck construction which permits the ingress of air into a plastics bottle 1 but prevents the egress of the bottle contents comprises a two-part plastics closure 23, 6 of which the inner part 6 has inner and outer co-axial tubular walls 11, 10 pushed on to the plastics bottle neck 2. Two diametricallyopposite flats 18 on the outside of the inner wall 11 leave gaps between the wall and the inner surface 15 of the bottle neck 2. A peripheral bead 3 around the bottle neck 2 engages the inner surface 12 of the outer wall 10. Axial ribs 25 are formed around the outer surface of the outer wall 10; during the process of moulding, these ribs contract to form recesses (26), Fig. 3 (not shown), around the inner surface 12, Fig. 1, of the outer wall 10. These recesses (26) thus form small gaps between the inner surface 12 of the outer wall 10 and the peripheral bead 3 around the outer surface of a bottle neck 2. The lower surface 20 of the outer wall 10 is an interference fit on a shoulder 5 around the base of the bottle neck 2. The arrangement is such that, should the pressure within the plastics bottle 1 fall, due to absorption of air into its contents, &c,. air will be drawn in from the ambient atmosphere through the gap between the lower surface 20 and the shoulder 5, through a tubular space 21 between the outer wall 10 and bottle neck 2, through the gaps (26) and the bead 3 into a tubular space 4 between the outer wall 10 and the bottle neck, and thence through the gap 16 formed by the diametrically-opposite flaps 18 on the outside of the inner wall 11 into the bottle. However, should the contents of the bottle 1 attempt to escape through the gaps 16, &c., the gaps (26) and the engagement between the lower edge of the skirt 20 with the shoulder 5 will both act as traps. The crown 9 of the inner closure member 6 is formed with a discharge hole 22. A lid 23 is moulded integrally with the inner member 6, and is hinged to the inner member. A spigot 24 inside the crown of the lid 23 is snapped into the hole 22 to closure the bottle.

Abstract: 1,142,552. Making sheets; working at specified temperatures. ARMCO STEEL CORP. 11 Nov., 1966, No. 50579/66. Headings B3A and B3V. [Also in Division C7] Low-carbon steel and ingot iron sheet having carbon up to 0À1%, manganese 0À01 to 0À40% and sulphur up to 0À05%, or such materials additionally having silicon up to 1À8%, are produced with either a (110), [001] or a (112), [110] preponderant orientation by hot-rolling, coldrolling, and subjecting the cold-rolled stock to a final anneal the first stage of which effects grain growth in the presence of sulphur, selenium or a decomposable compound of one of these and is followed by a secondary recrystallization under box annealing conditions at 1550-1650 F. To produce a (112), [100] orientation the cold reduction should be in excess of 90%, whereas a reduction of less than 90% will result in a (110), [001] orientation. The preferred finishing temperature for hot rolling is above 1600 F., with coiling at less than 1300 F., in order to obtain a fine grain size; alternatively it may be necessary to follow hot-rolling with a normalizing treatment at a temperature above 1625 F., preferably at 1800 F. Inter-stage annealing, if required during cold rolling, is carried out at 1100- 1800 F., while the stock is preferably decarburized, e.g. 1500 F. preferably after coldrolling, but possibly prior thereto. By treating the stock in the form of an open coil, the decarburizing primary and secondary recrystallization anneals may be carried out in the same furnace, the atmosphere and temperature being changed as necessary. Sulphur may be provided during the final anneal by incorporating elemental sulphur in the annealing separator (which may be magnesia, alumina, titanium oxide, calcium oxide or other refractory oxide) in an amount of ¢ to 10% by weight of the separator, or by incorporating an equivalent amount of a decomposable sulphur compound; alternatively a gaseous compound such as hydrogen sulphide, sulphur dioxide or sulphur hexafluoride may be present in the furnace atmosphere, to the extent of not less than 750 p.p.m. of hydrogen sulphide or its equivalent. In a further modification hydrogen sulphide may be added to the decarburizing atmosphere under such conditions that a surface layer of iron sulphide is formed of thickness 0À02 mil to 0À1 mil, from which sulphur is subsequently diffused into the grain boundaries during the subsequent final annealing step.
