Abstract: Astract of the Disclosure A strong, seamless one-piece metal bottle of substan-tially uniform wall thickness for containing and dispensing gas under pressure is produced from a flat metal piece by a series of deep-drawing operations to provide an elongated cylindrical shell having an open end mouth and a slight flange thereabout.  A dim-ple is formed in its bottom end wall.  The flange and an adjacent cylindrical open end mouth portion of the shell is then severed from the main body, and the wall thickness of the new open end mouth portion is tapered from the cylindrical side wall of the shell towards its mouth edge.  Thereafter, the tapered open mouth end portion is turned or swaged inwardly into a somewhat blunt, rounded-in nose portion of a substantially uniform thickness that substantially corresponds in the thickness to the side and bottom walls of the formed metal bottle and that has an open end of re-duced size suitable for mounting a nipple, ferrule or valve fit-ting therein.

Abstract: REFRACTORY HARD METAL CONTAINING TILES FOR ALUMINUM CELL CATHODES     Abstract of the Disclosure This invention relates to electrolytic reduction cells for aluminum production wherein tiles have been placed upon the cathode surfaces to improve the cell operation.  These tiles have aluminum-wettable surfaces, which reduce electrical losses and increase cathode life.  The tiles are produced from a mixture of refractory hard metal (RHM), a thermosetting resin, carbonaceous fillers and carbonaceous additives.  The tiles are physically formed, polymer-ized and/or cross linked, and carbonized so that they can be inser-ted into a cell.  The tile may have the RHM homogeneously dispersed throughout the tile structure, or it may have the RHM concentrated in layered form.

Abstract: POWER TRANSMISSION CHAIN-BELT            ABSTRACT:      A power  transmission chain-belt  (30),  especially adapted to provide a drive and transmit power between the pulley of a pulley transmission, such as a variable ratio pulley transmission.   In such each pulley has a pair of flanges, at least one of which is axially movable with respect to the other.   The chain-belt is con-structed of a plurality of ranks or sets of interleaved links, each rank being joined to the next adjacent rank by pivot means, such as round pins, or a pin and rocker, to permit articulation of the belt.   Generally trape-zoidal-shaped load blocks  (44,46)  are located between the pivot means of each rank or set of links, which blocks have opposite edge surfaces to drivingly contact the flanges of the pulleys.  At least one load block has a different width than the other load blocks, so as to contact the flanges of the pulley at a different radial location and different time than the other load blocks. Because  of this  construction,  the generated  noise pattern produced when the chain-belt engages the pulley flanges  is modified.

Abstract: A colour cathode ray tube including a screen (16) comprising at least two sets of phosphor stripes luminescing in different primary colours.  A channel plate electron multiplier (44) is mounted parallel to, but spaced from, the screen (16). The electron multiplier (44) comprises a stack of juxtaposed substantially planar apertured dynodes (Dl to Dn) with the apertures therein aligned to form channels.  An apertured extractor electrode (48) is mounted on the output side of the electron multiplier (44).  Preferably two or more foraminous deflector electrodes (50, 52) are mounted on the extractor electrode.  The apertures in the foraminous deflector electrodes (50, 52) have the same pitch as the channels of the electron multiplier but are offset laterally relative to each other and to the axes (A) of the channels by amounts which allow the emergent electron beam from each channel to pass through to the screen (16) without impinging upon the deflector electrodes (50, 52).  By applying a potential difference between the deflector electrodes (50, 52) an electron beam emerging from its respective channel is deflected laterally onto a respective one of its associated group of phosphor stripes.  The apertures in the deflector electrodes (50, 52) may be circular, elliptical or polygonal for example square, rectangular or hexagonal.
