Abstract: 1,098,252. Fluid cushion conveyers; slipways; vehicles guided and supported by gaseous cushions. SOCIETE BERTIN & CIE. Jan. 4, 1965 [Jan. 2, 1964], No. 227/65. Headings B7K, B7L and B7S. A conveyer, e.g. for ships, comprises a platform 1 supported on a track 2 by a liquid cushion contained by skirts 11 fixed to the platform or the track. As described, the track is inclined to form a ship lift, the ship either floating on water carried by the platform, or resting on inflatable bags. In one embodiment, a plate carried by the platform extends into an inclined gutter 5 running alongside the track to form a moving dam, allowing water to be withdrawn by a pump 6 for supply through passages 8 to the cushions. The. pump may be driven by a heat engine 7, or by an electric motor supplied from an overhead cable. The platform is propelled by rack and pinion drive 14, 16, and has abutments (10, Fig. 4, not shown) to support it when the cushions are not pressurized. In another embodiment (Fig. 5, not shown) water under pressure is supplied to valves (18) in the track, each surrounded by skirts (10a) and opened by contact with the platform passing over them to permit the water to form a cushion beneath the platform. Where the track changes in slope, the platform may have pivotally mounted fluid cushion "bogies" (Figs. 10 and 11, not shown).

Abstract: 468,508. Colour photography. GASPAR, B. Jan. 6, 1936, No. 507. Convention date, Jan. 5, 1935. [Class 98 (ii)] A method for producing colour photographic or kinematographic picture images and more particularly kinematographic colour films bearing sound records, in which dyestuff images are combined with a metallic silver image, or an opaque metallic compound image, is characterized in that there is employed material containing dyestuff-forming substances or dyestuffs in the light sensitive layer and in that the production or destruction of the dyestuff is effected by reagents which do not dissolve the silver halide, there being produced, after the production or destruction of the dyestuff, in the layer which is still light sensitive, or in which the light sensitivity is restored, an additional picture or sound record in the form of a metallic silver image or an opaque metallic compound image. In one example three colour component images are printed from positives on to threelayer material having a green-sensitized layer containing Diamine Pure Blue FF on one side of the support, and a red-sensitized layer containing Chrysophenin G and a blue sensitive layer containing Diamine Fast Pink G on the other side. The material is developed, but not fixed, the dyestuffs are destroyed at the silver image by a 2 per cent solution of hydrobromic acid, and the silver rehalogenized with a solution of potassium dichromate and hydrochloric acid or of cupric bromide or of potassium ferricyanide and potassium bromide. The film is washed, clarified with sodium bisulphite and dried, the sound record and a black-and-white key print printed from appropriate negatives, and the film re-developed and fixed. The material may have a colourless silver halide emulsion layer. Layers containing dyestuff-forming substances such as leuco-esters of vat-dyestuffs, in particular the leuco-ester of thioindigo pink may be used. The dyestuffs or dyestuff-forming substances may be introduced into the photographic layer after exposure. Specifications 379,679,416,566, and 416,660 are referred to.

Title: Improvements in apparatus for indicating the speed of a vessel in motion in a fluid
IPC: G01P5/20
Filed: 1924-01-08
Abstract: 220,225. Baule, M. E. A. Jan. 8, 1924. Logs.-In apparatus in which the ship &c. carries a longitudinally disposed conduit through which the water &c. flows, the conduit is provided at one end with an admission device and at the other end with a. similar discharge device, each device comprising a cylindrical or conical body 3 open at its outer end and provided with a number of additional orifices 4 regularly disposed over its surface. The open end may be covered by a strainer 8. The body is ccnnected to the conduit 10 by a conical part 5 and a tube 6, the latter having a restriction within it to reduce the velocity of flow through the conduit. To measure this velocity means, such as an air reservoir 12, Fig. 4, are provided for periodically discharging bubbles into the conduit, which pass over an insulated contact-plate 15 and break the circuit of an electromagnet 17 controlling a scribing arm &c. 20. The velocity is obtained by measuring the interval between the emission of a bubble and its passage over the plate 15. The means for discharging bubbles may be controlled by a second electromagnet in circuit with the magnet 17 so that the emission of each bubble synchronises with the passage of the preceding bubble over the contact plate, the speed then being deduced from the rate of emission of bubbles. Fig. 6 shows means for delaying the re-closing of the circuit to avoid errors due to parasitic bubbles &c. The armature 29 has an arm 35 carrying a contact 36 connected to the winding of the magnet, and normally in contact with an earthed contact 38 carried on an arm 37 secured to the piston 40 of a dashpot, the contacts 36, 38 being urged together bv a compression spring 39. When the circuit is broken the armature is drawn upwards by the spring 30 and is slowly followed by the arm 37. The conduit may be made sinuous in the vertical plane. To measure the drift angle a second conduit may be provided at right-angles to the first; a spindle passing through both conduits carries a vane in each conduit and also carries a pointer which indicates the drift angle on a scale.
