Title: Improvements in and relating to life-saving apparatus
IPC: B63G8/41
Filed: 1922-10-23
Abstract: 208,617. Gray, J., (Tribe, C. R.). Oct. 23, 1922. Submarine vessels.-Apparatus for saving the crew of a submerged vessel comprises a lifesaving buoy 4 housed in a cylindrical chamber 2 fitted inside a water-tight safety chamber 1, positioned in the hull of the vessel, in which the crew assemble and from which they enter the buoy through the housing chamber 2, means being provided for enabling the buoy to rise to the surface. The buoy is provided with a water ballast tank 38 and a mooring wire 23 attached to a drum 21 positioned in the chamber 2, the drum being rotated to lower the buoy from the surface bv a hand or electric winch 5 mounted in the chamber 1. Communication is established between the chamber 1 and buoy through watertight. doors 31, 37 and the buoy is forced from the housing by filling the housing with ater by a hand or electric pump 65, 68 positioned in the chamber 1, additional pressure in the chamber 2 being raised by the occupant of the buoy by means of a pump 47 fitted therein. When the occupant leaves the buoy and closes the port 36, he floods the ballast tank 38 by operating a hand wheel 43 and the buov is hauled down into the chamber 2, water escaping therefrom by pipes 72, 70 leading to a tank 63 in series with the pumps. The core of the mooring rope 23 may be a telephone cable connected to a telephone 54 inside the buoy and a plug 55 on the top thereof so that communication may be established between the submerged vessel, the buoy and a surface vessel.

Abstract: 1,144,453. Polyimide containing laminates. E. I. DU PONT DE NEMOURS & CO. 28 June, 1966 [29 June, 1965], No. 28869/66. Heading B5N. [Also in Divisions F2 and H1] A method of making a laminate comprises laminating by heat and pressure a film of a polyimide to an adherable surface of a film of a copolymer comprising 95 to 50% by weight of tetrafluoroethylene and 5 to 50% by weight of hexafluoropropylene, and then heating the laminated films at 350‹ to 500‹ C. for at least one second. The adherable surface is formed by subjecting the copolymer film to an electrical discharge treatment preferably at a temperature of at least 50‹ C. An adhesion promoter, e.g. polyethylene imine, may be used. Preferred laminates made by the process comprise (a) copolymer film/polyimide film/copolymer film and (b) copolymer film/polyimide film/copolymer film/aluminium/copolymer film. The products may be used in the manufacture of spiral wrapped ducts and tubes and for the insulation of electrical conductors.

Title: Improvements in and relating to windlasses
IPC: B66D1/72
Filed: 1919-11-21
Abstract: 159,026. Macfarlane, G. T. Nov. 21, 1019. Drum or barrel winding-machines; driving-gear for winding and paying-out apparatus; selfsustaining gear.-Relates to driving-gear for windlasses or capstans and comprises a driving- gear in which a motor running in one direction is connected through reversing-gear to an epicyclic or like clutch capable of sensitive control which is geared to the windlass &c. The motor a drives, through gearing g, a short shaft h connected by bevel-gearing to reversing bevel-wheels clutchable to a shaft l carrying an epicyclic gear t, Fig. 4, which drives a bevel-wheel z geared to a vertical shaft 12 which in turn drives the chain-lifters &c. 17. mounted on the ship's deck, the motor &c. being below the deck. The brake band p is suitably operated to control the epicyclic gear. The chain-lifters 17 are provided with a ratchet device controlled by a ring 20 which is angularly adjustable to put the pawls into or out of action. A brake drum 30, Fig. 8, is mounted on the outer side of each chain-lifter, the brake coils 31 being controlled by loose brake rims 32 to which one end of each coil is fixed. The brake rims can be held by brake-bands 33. This constitutes a selfsustaining gear, since when the coil-brake is hard on the load cannot run back, even when the driving-clutch is disengaged, while when the driving-clutch is engaged the chain-lifter can rotate freely. Another form of self-sustaining gear is also described in which a loose brake rim carries pawls engaging with a ratchet-wheel secured to the chain-lifter. The pawls are linked to blocks sliding with slight friction in grooves in the ratchet-wheel, so that while the chain is being lifted, the pawls are put out of action. A positive connection between the shaft and the chainlifter for driving the latter in either direction can also be effected when desired. For this purpose a member that can slide axially but not rotate on a sleeve keyed to the shaft carries dogs 40 which are capable of engaging the polygonal interior of the drum 30, when operated by a screw through the medium of the hand-levers 45.

A bagasse or like furnace comprises a front wall, side walls and a vertically extending rear wall and has an externally arranged feed chute which is in direct communication with the interior of the furnace through a feed opening, and which is arranged so that bagasse feeds naturally from the chute into the furnace to build up a fuel bed in contact with the said walls and filling the feed opening, the fuel bed having one face inclined at the natural angle of repose of the bagasse and extending between the feed opening and a position intermediate the height of the rear wall, which latter is provided with primary air passages below said position. The furnace shown comprises a pair of conbustion chambers 1 each of which is fed with bagasse &c. by a hopper 7 through a wedge-shaped opening .6 disposed at the top of the front wall 2. From the opening 6 which does not extend across the entire width of chamber each chamber roof 5 extends towards the rear wall 4 at an angle equal to or greater than, the angle of repose of the bagasse B. Primary combustion air is supplied from the duct 9 to the openings 8, 10, whilst secondary air is supplied via duct 11 and openings 10. Tertiary air is supplied through openings 13 in the side walls of the exit flue passages 12 leading from the combustion chambers whilst any deposited slag is removed through openings 15. The combustion gases may be utilised for steam generation and ash is removed from each chamber 1 through an opening 14. In an alternative arrangement the opening 6 extends across the entire width of each chamber. The combustion may be controlled by varying the amount of combustion air supplied.

The trough 14 supporting the needle ring 2 is itself supported on a bush 20 journalled, on roller bearings 22, in a recess at the top of the supporting column 23. The drive shaft 13 of the machine is driven from a shaft 25 by a coupling 24, an adjustable slipping clutch 31 being provided. The trough is tiltable about a pivot pin 39 to permit inspection of the gearing fitted in the lower part of the machine. The machine may be held in the tilted position by a locking device. In one modification to the drive (Fig. 6, not shown), a motor drive shaft in the column 23 is connected to the drive shaft 13 by means of a belt drive which includes a countershaft mounted in the trough. In another modification (Fig. 4, not shown), a driving motor is mounted in the trough in place of the countershaft and drives the shaft 13 by a single belt. Power to the motor is supplied to the rotatable trough by slip rings. The invention may also be applied to linking machines wherein the supporting column is displaced from the machine axis, and to machines suspended from an overhead anchorage.

Title: Hard metal alloy and method for producing the same
Filed: 1954-10-20
Abstract: A hard metal alloy, particularly for tools, is produced by sintering a mixture of 78-80 per cent tungsten carbide (WC), 2-4 per cent tantalum carbide (TaC), 3-5 per cent titanium carbide (TiC), 12-15 per cent cobalt and 0-3 per cent of one or more carbides of metals of Groups 4a, 5a and 6a (excluding tungsten, tantalum and titanium) and/or one or more nitrates, borides or silicides of metals of Groups 4a, 5a and 6a under such decarbonizing conditions that total percentage of carbon is reduced to 0.2-0.5 per cent less than stoichiometric amount and the per centage of free carbon is less than 0.1 per cent.  The decarbonizing conditions may be obtained by packing the mixture in powdered aluminium or zirconium oxide and graphite or by sintering in vacuum.  In an example, 79 per cent tungsten carbide, 3 per cent tantalum carbide, 4 per cent titanium carbide and 14 per cent Co were mixed after first heating the carbides together at 1700 DEG C. The resultant mixture was then packed in a powder of 85 per cent aluminium oxide and 15 per cent graphite and sintered at 1400 DEG C. The total carbon content of the resultant compact was 5.5-5.65 per cent and the free carbon content was 0.05 per cent.
