IPC: G06T15/00
Filed: 2006-09-29
Abstract: Memory's first and second portions stores object data for divided image's rectangles and depth data (object data derived) respectively. Further object data replaces part of contents, repeated until no more exists. Image and shading data (depth data derived) displayed. Object data is stored in memory for each rectangle's objects by allocating portion per rectangle. Portion allocated global list storing data of objects crossing multiple rectangles. Each rectangle's data supplied from respective portion and, if required, from global list, derives rectangle's image and shading data. Latter stored for display. Subdividing rectangles is disclosed. Memory comprises portions storing data for each rectangle's objects and pointers from each subdivision to subdivision's objects data. Image objects are divided triangularly, data defining triangles, vertexes and pointers between. When processing subdivisions, system fetches vertex data once using pointer from each subdivision to triangle data for subdivision's objects and pointer between that triangle and vertex data.

Drawings to Specification. [Class 91] [Also in Group IV] Mercaptans, alkyl phenols, thiophenols, and other weakly acidic impurities are removed from such water-insoluble neutral or basic organic liquids as gasolene, kerosene, pentane, hexane, benzene, toluene, xylene, carbon tetrachloride, dichlorethylene, chlorpropane, and nitrogen bases, e.g. alkylated pyridines by extraction with an aqueous solution of a strong base in which is dissolved a substantial amount of at least two solubility promoters for the acidic impurities, one promoter being a phenolic-hydroxy-aromatic compound having oxidation-inhibiting properties and the other an aliphatic or aromatic promoter other than a phenolic-hydroxy-aromatic compound, both promoters having B.P. higher than water, being inert to the strong base, and being substantially insoluble in the liquid treated, and mixtures of alkyl phenolates with alkali salts of fatty acids with 3-5 C atoms being excluded.

Title: Improvements in or relating to electron discharge apparatus
IPC: H01J31/28
Filed: 1936-04-04
Abstract: 473,006. Cathode-ray tubes. BAIRD TELEVISION, Ltd., and JONES, V. April 4, 1936, No. 10009. [Class 39 (i)] For generating an image signal an optical image is formed on a photo - electric cathode and a corresponding charge image formed on a storage grid electrode partially permeable tc electrons, which image is scanned by an electron beam, electrons emitted from the storage grid being collected on an electrode connected to a load impedance across which is generated the image signal or the direct current and lower frequency alternating current components thereof. The Figure shows an arrangement in which the photo-electric cathode 2 and the electron gun 5 are on opposite sides of the storage electrode 3. The electric image formed on the cathode 2 is focussed on the electrode 3 by a coil 4. The collecting electrode 6 is a wide meshed grid and the scanning beam passes through it ; alternatively such an electrode may be placed between the cathode 2 and the storage electrode 3. The electrode 3 may be formed of a grid of insulated wire on to which metal is sputtered in such a way as to form discrete deposits extending partly round the wires of the grid, or discrete insulating particles may be deposited on uncoated wires. In an alternative arrangement the photo-electric cathode and the electron gun are on the same side of the storage electrode. The storage electrode may be negatively charged by the photo-electrons from the cathode 2 and discharged by secondary emission produced by the cathode ray, or positively charged by secondary emission produced by the photo-electrons and discharged by the cathode ray. The photo-electrode may be transparent.

Patent GB-375865-A (GB)
Title: Method of and means for electrically purifying gases, non-conducting liquids and thelike
IPC: B03C3/66
Filed: 1931-04-02
Abstract: <PICT:0375865/III/1> <PICT:0375865/III/2> In a process for the electrical purification of gases, nonconducting liquids, such as oils &c., the discharge electrodes are supplied with impulse potentials of such short duration that the time occupied by each impulse, e.g. 10,5 second, amounts to only a very slight fraction of the time between two successive impulses, thus allowing a much higher potential to be applied to the discharge electrodes without spark-overs occurring. Impulse potentials of a definite polarity are preferred to those of an alternating type.  A suitable arrangement for attaining this effect is shown in Fig. 1, wherein an impulse spark-gap 9 preceded by an earthed condenser 10 is inserted in the feed line 7 to the electrofilter 8.  The spark gap is preferably cooled by a current of gas to prevent arcing.  The supply cable 13 may also be arranged to act as a capacity by earthing its covering.  The transference of high frequency oscillations through the line 7 which might cause interference in wireless apparatus &c. is prevented by means of a resistance 12 and a choke 11.  The frequency of the impulses may be varied from a few to several hundreds per second by alteration of the potential, capacity and resistance in the supply line to the filter. Suppressed impulse potentials in which the potential does not rise above a predetermined value may be used and are obtained by connecting a retarding resistance 14 directly in front of the filter 8 and in front of that, and in parallel with the filter, an adjustable spark-gap 15 which is earthed and has no retardation.  The potential height of the impulse is altered by varying the length of the spark-gap 15.  To prevent a complete discharge of the filter, a condenser 16 shunted by a resistance 17 is arranged in the earthed lead to the spark-gap 15.  When this spark-gap operates to prevent a flash over in the filter 8, the condenser 16 is charged and discharges through the resistance 17 leaving a sufficient charge on the electrodes of the filter to ensure the separation of the dust particles.  In large installations, it is preferable to subdivide the discharge electrodes and supply each section in rotation.  The sections may also be isolated from the supply line at the moment of discharge so that the reactive effects cannot damage the transformers, rectifiers, &c.  As shown in Fig. 2, a rotating switch 18 is arranged between the poles of the spark-gap 9 and a third contact 19 is connected to the smaller condensers 20, 21, 22.  These condensers are first charged from the impulse condenser 10, and then, on further rotation of the switch, are discharged on to the filter 8. During the last operation, they are isolated from the supply line 7.
