Title: Improvements in screws for watercrart
IPC: B63H5/14
Filed: 1928-09-24
Abstract: 310,268. Kort, L. Sept. 24, 1928. Propelling by jets; propeller shaft arrangement; driving arrangements for screw propellers. -A ship is provided with a tunnel from bow to stern in the forward part of which works a screw at the position of minimum cross-sectional area, the tunnel converging more rapidly towards this point than the after part of the tunnel diverges therefrom. The forward part may be in two sections between which is located the power plant. The tunnel t, Fig. 2, has a. propeller s situated at its minimum diameter and at its front is divided by a portion of the hull which contains the driving motor m. The motor may, however, be placed in the after body of the ship and drive a screw by a forwardly projecting propeller shaft. In some cases the change in cross sectional area of the tunnel is obtained by alteration of the horizontal dimension leaving the height of the tunnel constant. In an alternative form of drive, the motor is supported in a boss in the tunnel and carries the screw propeller directly. In other forms the drive is by means of gearing so supported in the tunnel and connected with an engine in the hull. In another modification the rim of a screw propeller fits in a groove in the tunnel and carries external blades on which water or gases under pressure are caused to impinge and rotate the screw.

Abstract: 1,221,698. Non - woven web; stretching fabrics. VETRERIA ITALIANA BALZARETTI MODIGLIANI, S.p.A. 10 June, 1968 [10 June, 1967], No. 27464/68. Headings D1N, DlR and D1S. [Also in Divisions B8 and F2] A tube of mineral fibres is made by winding a strip N of fibrous felt spirally onto a mandrel 12 and axially removing the tube from the mandrel. The strip is formed by depositing the fibres on a collecting surface and importing to the strip as it so formed a curative in its own plane. As shown, the strip is formed from a gas suspension of fibres passing through hood 22 onto the surface of a rotating perforated cone 20. Since the larger periphery of the cone moves faster than the smaller periphery, a curved strip will be formed. A suction flue 24 assists in collection of the fibres. Bonding agent, fillers and additives can be added to the fibres. The distribution of the fibres across the width of the strip can be varied by baffles or blowers or by using different diameter holes and/or selectively located holes in the cone 20. The strip can be differentially stretched across its width so as to modify its curvature. The strip can be made thickest where it will be subjected to most stretching.

[Also in Division H2] A compressed-air braking system for vehicles comprises two independent sections each supplying air via separate sections of a driver's valve to brake-operating devices which are common to both sections, the devices being adapted and arranged so that if one section fails the force exerted by the devices on the brake-applying members is unaltered, and an electro-pneumatic signalling device which signals to the driver the failure of either section of the system. As shown, an engine-driven compressor A supplies air to a pressurereducing valve B including check valves B1, B2 feeding separate sections of the system, each section comprising a reservoir C1 or C2 maintained charged by the compressor, a respective section of a two-section distributer control valve D operated by foot pedal F to determine braking pressure, and controlled-pressure lines G1, G2 each leading to front and rear sets of brake cylinders H, K. Each cylinder is of the kind disclosed in Specification 986,537, i.e. it is provided with two mechanically interconnected pistons defining two power chambers communicating with the respective lines G1, G2, the pistons being connected to a common link H1 or K1 for connection to the associated brake applying member, such that regardless of whether pressure is supplied to one, the other or both chambers the same force is produced to operate the brake applying member. The electro-pneumatic signalling device L is arranged to operate a warning device 36, e.g. a lamp, when failure in one of the sections occurs, and comprises a pair of cylinders 14, 15, Fig. 3, communicating respectively with lines G1, G2, and containing pistons 20, 21 acting via springs 18, 19 on opposite ends of a balance beam 24 rockable about pivot 26. In operation, unbalance between the pressures in lines G1, G2 causes rocking of a cam 30 supported by the beam 24 to close switch contacts 32, whereby the lamp is energised in either direction of unbalance. In a modification (Fig. 2, not shown) the front brake cylinders H are replaced by conventional cylinders having a single piston and connected only with the line G1, only the rear brake cylinders K being operable by both sections of the system. Specification 986,537 is referred to.

Abstract: 1478890 Metal coating refractory metals OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES 21 June 1974 [26 June 1973] 27764/74 Heading C7F [Also in Division B3]  A refractory metal surface e.g. Ta, Nb, Zr, Mo, W, Ti or their alloys is coated with a metal by applying a dispersion of brazing metal halide particles in a non solvent liquid and heating to a temperature sufficient to form a refractory metal halide which is more volatile than the brazing metal halide and to deposit the brazing metal. The brazing metal halide may be a fluoride or chloride of Ag, Cu, Ni, Al, Cr, Fe, Sn, Zn, Co. The dispersion may be formed by grinding the halide e.g. Ag Cl, in cyclahexanone containing 2% methyl polymethacrylate and applying to the substrate by brush, spraying or by immersion. The coated substrate is then heated at 400-800C in vacuum or an inert gas to deposit the brazing metal and volatilize the formed refractory metal halide. Further metal, preferably the same metal, may then be electro-deposited or fused on to the coating and the coated refractory metals brazed together via the coating. Coating and brazing may be effected together by placing a metal film between two brazing metal halide coated substrates and heating to brazing temperature.
