Patent CA-1168288-A (CA)

Abstract: ABSTRACT OF THE DISCLOSURE         A novel electron gun for use in television cathode ray tubes of the direct view or projection type is disclosed.  The cathode ray tube has associated therewith a power supply for developing a predetermined pattern of operating voltages including first and second adjustable voltages.  The electron gun has electrodes aligned on an axis for receiving the operating voltages to produce a focused beam of electrons.  The electron gun comprises lower end means for generating an electron beam having a crossover.  The beam expands in a prefocusing section following the crossover and the outer rays of the expanding beam define a half-angle with respect to the axis.  The gun also comprises main focus lens means for receiving the expanding beam and focusing the beam to form a beam spot of minimum size at a predetermined distance from the gun.  The main focus lens means has at least a focusing electrode for receiving the first adjustable voltage for focusing the beam spot.  The main focus lens means, by its inherent characteristics, is capable of focusing a minimum beam spot whose size is a function of the beam half-angle.  The gun according to the invention is characterized by having at least one-half angle control element located in the region between the lower end means and the focus lens means.  The control element according to the invention receives the second adjustable voltage to generate a half-angle control field of adjustable strength. Voltage adjustment means are provided for adjusting the second adjustable voltage such that upon adjustment of the voltage adjustment means to increase the strength of the half-angle control field, the half-angle is increased.  Conversely, upon adjustment of the voltage adjustment means to decrease the strength of the field, the half-angle is decreased.  As a result, an optimum half angle providing a minimum beam spot size is attainable.

Abstract: Abstract of the Disclosure The invention is directed to the separation of nickel and cobalt contained in hydrometallurgical by-products such as hydrates and carbonates occurring in plants adapted to work up nickel, copper and cobalt ores wherein a slurry of the initial oxidized material is reduced by hydrogen under pressure in the presence of cobalt metal.  The nickel content of the slurry is removed by pressure carbonylation and the remaining solution, after filtration to remove precipitated impurities, is acidified to produce cobalt hydridocarbonyl which is removed from the reaction mixture by sparging with a reducing gas and is collected.

At least two adjacent focuses F and F', at least one reflecting interface H and directions such as (D1) and (D2) are selected in the sub-surface.          A seismic trace, from which a portion containing the effect due to the reflecting interval is extracted, is made to correspond to each direction and to each focus.          The correlation function between the two trace portions relative to two adjacent focuses and the same direction is then determined.  The correlation functions obtained are finally summed for the different directions.        Application to high resolution seismic prospecting.

Abstract: La présente demande concerne un générateur de plasma comprenant un tube métallique de petit diamètre à l'intérieur duquel on peut faire circuler un gaz tel que de l'argon à un faible débit, qui s'échappe à l'extrémité antérieure du tube. Ce tube est couplé à une structure excitatrice qui peut comprendre un générateur de fréquence alimentant par une liaison coaxiale une structure de couplage permettant le transfert de l'énergie du générateur à la partie antérieure du tube métallique. En l'absence d'un courant de gaz dans ce tube, cette partie antérieure rayonne l'énergie qui lui est transmise à la manière d'une antenne. Lorsqu'un gaz s'échappe à l'extrémité du tube, cette énergie permet d'entretenir un plasma à l'avant de celle-ci. Ce dispositif générateur de plasma peut recevoir des applications, notamment comme chalumeau, source lumineuse ou torche utilisable en spectrographie, moteur à plasma ou source d'ions.

Abstract: ABSTRACT OF THE DISCLOSURE                   The plate-, foil- or strip-shape support materials for offset printing plates are based on chemically, mechanically and/or electromechanically roughened aluminum, or on one of its alloys. Optionally, the aluminum may also have an aluminum oxide layer produced by anodic oxidation.  One of the two surfaces the support material has a hydrophilic coating of at least one salt-type hydrophilic organic polymer which is a complex-type product obtained by reacting a) a water-soluble organic polymer having acid functional groups con-taining phosphorus or sulfur (for example, polyvinyl-phosphonic or polyvinylsulfonic acid) with b) a salt of an at least divalent metal cation.           In a process for manufacturing this support material, the complex-type reaction product, dissolved in an aqueous acid, is applied to at least one surface of the support material and the support material thus modified is dried.  It is also possible however, to produce the complex-type reaction product of the components a) and b) on the support material. The support material is used in the preparation of offset printing plates having a light-sensitive layer.

Abstract: ABSTRACT OF THE DISCLOSURE           Opening arrangements for packing containers which are manufactured from a flexible material and intended for pressurized contents, e.g., beer, are sometimes in the form of a tear-off cover strip which is sealed to the packing con-tainer wall and covers punched out pouring opening.   In order to withstand the high internal pressure caused by the contents, the seal between the cover strip and the packing material must be strong, which detrimentally affects the openability of the packing container.  By ensuring that the mutual bond between the different layers in the packing laminate is weaker than the seal between the cover strip and the outer layer of the container material, a readily opening packing container is provided, in spite of the seal between the cover strip and the packing laminate being of a strength such that the risk of leakage or unintentional   opening is small.  By sealing the cover strip in a zone extending around the pouring opening which is at a small distance from the  actual pouring opening and by providing -the pouring opening with a "set in" pouring edge, the properties of the opening arrangement are optimized further without increasing the risk of leakage or making the handling more difficult.

Abstract: ABSTRACT:              A pal comb filter having a first and a second parallel transmission path.  The first path includes a time delay network.  This time delay network has a time delay equal to one line period N instead of two line periods as in conventional PAL comb filters.  For this purpose a PAL inverter is arranged in one of the two paths.  Alternatively, this PAL phase inversion can be switched in such a way that this inversion is effected either in the first or in the second path, change-over causing an additional PAL phase inversion of the output signal of the comb filter, which may be employed in video recording systems with parallel tracks in which the PAL phase is aligned in directions per-pendicular to the tracks by use of additional PAL phase inversions during recording, and in video recording systems in which this alignment is not used, in order to ensure, inter alia during fast-motion playback, that the PAL phase inversion sequence in the reproduced signal is not disturbed.

Abstract: ABSTRACT           A belt conveyor is disclosed which is adapted for steep or vertical conveyance of loose particulate materials even at high conveying speeds.  A second conveyor belt serves as a cover belt in the discharge region of the discharge drum.          The cover belt comes into close proximity with the carrier belt in the region of the discharge drum to catch particles which are expelled under centrifugal force and to guide such particles into the discharge stream.  The high dispersion of previous L-conveyors is thereby avoided and it is possible to utilize the minimum size conveyor belt needed for the conveying capacity.  The trajectory of the discharge stream may be adjusted by altering the path of the cover belt by means of an adjustable deflector drum.
