Title: Soap or other tablet or block covered with a soft sheath
IPC: C11D17/04
Filed: 1937-05-08
Abstract: <PICT:0495480/III/1> Blocks or cakes of soap or the like 2 having circumferential grooves 1 substantially parallel to the surface S being used are fitted with a pliable, preferably elastic, waterproof sheath 3 retained by an elastic ring 3a pressing the sheath into one of the grooves; as the block wears down the sheath and ring are drawn downwards by the folded end 3e, the sheath sliding over the ring if they are not united.  The sheath is usually of rubber, the ring of rubber or spring steel.  The buoyancy may be increased, so that the block floats with the exposed parts out of the water, by enlarging the recesses 1, by enclosing light material, e.g. sponge rubber in the folded end 3e of the sheath, and by folding the free end 3b of the sheath about a framework; the block may also be formed with an air-chamber 8.  The sheath may have (1) a widened mouth to facilitate fitting on to a new block and the taking hold of the end 3e,; it is then preferably ribbed, narrowed, or tightened toward the open end to increase the grip on the block; (2) ribs 3m to fit into the lower grooves 1 and increase the hold on the block; the ribs may have recesses 3n in which the ring 3a will fit, and may be made tighter or of smaller circumference than the remainder of the sheath.

Title: Improvements in or relating to devices for restricting the entry of water into an air intake
Inventor: BENNISON MICHAEL JEREMY
IPC: B60V1/00
Filed: 1963-04-05
Abstract: 1,002,834. Gas turbine engine air intakes; fans; valves. VICKERS-ARMSTRONGS (ENGINEERS) Ltd. March 10, 1964 [April 5, 1963], No. 13762/63. Headings FIB, FIC and FIG. An air intake for supplying air to the engines and/or fans of an air cushion craft or for any vehicle or apparatus in which water may undesirably enter the air intake, comprises a duct having a flap pivotally mounted therein about an axis transverse to the direction of flow through the duct and springs acting between the flap and the duct to urge the flap into a position offering minimum resistance to the flow of air through the duct, the shape of the flap, the stiffness of the springs and the positioning of the pivotal axis on the flap being such that if water flows over the surface of the flap, the latter is displaced to restrict water flow along the duct. In the embodiment shown in Fig. 2, a single flap 3, which may be an aerofoil or a curved or flat plate, is pivoted about an axis 6 nearer its trailing edge than its leading edge. Should water flow over the surface of the flap, its balance is upset and hydrodynamic forces are exerted to rotate the flap against the force exerted by spring 9 so as to completely block thÚ duct. When water drains from the air intake mouth 1, the spring 9 returns the flap to the position shown. In a modification, Fig. 3 (not shown), a vertical series of flaps are mounted in the duct, those over which water flows rotating to block that part of the duct whilst the remainder maintain their horizontal positions allowing air to pass. In the arrangement shown in Fig. 4, when water flows over the lower of two flaps 12 and 13, flap 13 rotates (in an anti-clockwise direction) and opens the cover 21 of a drain 22 through linkage 15, 18 and 19 so that any water which flowed past the flaps before they blocked the duct is disposed of. In another arrangement, Fig. 5, more than a predetermined amount of rotation in either direction of a flap 24 is sufficient to energize servo-mechanism 32 which rotates a bell crank lever 35 thus blocking the duct 2 with a shutter 36. The shutter may be operated directly by the flap, without the servo-mechanism. A drain as shown in Fig. 4 may be mounted upstream of the shutter.

Abstract: 720,613. Discharging molten metal. IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 18, 1953, [May 30, 1952.] No. 13781/52. Class 51 (2). [Also in Groups II and XXII] A process for arcmelting and casting high melting point reactive metals and alloys such as titanium, zirconium, molybdenum, thorium, hafnium, tantalum, chromium, and their alloys, comprises melting a charge or charges in inert atmosphere or vacuum in a cooled crucible communicating through a centrally disposed orifice in its base with a separable mould, the said orifice being closed by means of an initially positioned plate of the same composition as the metal to be melted, under conditions such that a molten pool of metal at least sufficiently large to form the casting is formed and maintained below the electrode and thereafter melting the plate at least in part to permit the charge to flow into the mould. A lining of metal is first built up on the closure plate 15 by melting a small charge at reduced arc current, allowing it to solidify, and repeating the process several times. The main charge is then added and melted until the molten pool 16 penetrates to the plate 15 and the melt is cast into the mould 10. The formation of a large pool 16 is obtained by increasing the diameter and decreasing the length of the crucible as compared with water-cooled copper crucibles heretofore used.
