Abstract: ABSTRACT OF THE DISCLOSURE A voltage doubler circuit for providing half-wave direct current at a predetermined peak voltage level to a device, has a source of alternating current having a peak voltage lower than the predetermined peak.  A first capacitance element is connected in series with the device and there is at least one additional capacitance element and a switch for selectably connecting the additional capacitance element in parallel with the first capacitance element for providing different levels of current to the device.  A resistance element is connected between the capacitance elements for causing a voltage buildup on the additional capacitance element when the additional capacitance element is not connected by the switching means, whereby the peak voltage across the switch is smaller than the predetermined peak voltage level.  The internal charging resistor and two capacitance elements form an integral wound capacitor.

Abstract: BRITISH TELECOMMUNICATIONS                     A B S T R A C T         IMPROVEMENTS RELATING TO VIDEO DATA TRANSMISSION         A conditional replenishment video data trans-mission system involves the transmission of digital values representing the brightness changes at picture elements of a raster scanned image since the previous frame. Since nothing is transmitted for those picture elements without a significant brightness change, the amount of data to be transmitted will depend on the extent of movement in the image, and buffer stores are provided to allow the use of a constant transmission rate.  If the extent of movement in the image is very high the buffer store at the receiver will tend to fill up and might overflow.  In order to avoid this occurring, reduction of the amount of data to be transmitted by element subsampling has been proposed in which in a cluster of changing elements data relating to only some, for example alternate ones of the elements are transmitted, and interpolation is used at the receiver to calculate the brightness change data for the omitted elements.  The blurring of vertical edges in the image resulting from the interpolation is avoided by suspending sub-sampling where vertical edges are detected in the image. When in the sub-sampling mode, in order to avoid having to mark those normally omitted elements for which data are transmitted the receiver  is arranged to detect -? the presence of a vertical edge and respond by treating the data as if they relate to all elements in the vicinity of the edge and not just the sub-sampled ones.          Transmission error can result in the receiver being incorrect in the detection of edges, and to avoid this the number of quantizing levels during sub-sampling is reduced from 8 to 4, using one set of 4 codes for the normally present elements and the other set of 4 codes for the normally omitted elements.          Since a vertical edge will usually appear in more than one line, the receiver may be arranged to check the previous line for a vertical edge and anticipate the inclusion of normally omitted elements if such an edge has occurred.

Abstract: ABSTRACT            "METHOD AND MATERIALS FOR THE MICROBIOLOGICAL OXIDATION OF AROMATIC HYDROCARBONS "           Disclosed are novel DNA sequences susceptible to expression in a microorganism in the form of synthesis of one or more enzymes participative in the microbio-logical oxidative degradation of a selected aromatic hydrocarbon substrate to a selected oxidized compound which is an intermediate in a multiple enzyme-catalyzed degradative pathway for total mineralization of said substrate.  The DNA sequences are characterized by being substantially free from operative association with DNA sequences susceptible to expression in the form of synthesis of one or more enzymes participative in oxidative degradation of said selected intermediate compound.  Illustrative of the invention is a plasmid-borne DNA sequence of Pseudomonas putida origin which codes for expression, in a host microorganism such as E. coli, of enzymes participative in the oxidative degradation of naphthalene to salicylate.  Cultured growth of stably transformed host cells in a medium including a naphthalene substrate results in quantita-tive naphthalene degradation and accumulation of isolat-able quantities of, e.g., salicylate products.

Abstract: "MOVING BED GAS TREATING PROCESS"                  ABSTRACT           A gas treating process for simultaneous solid particle fil-tering and sulfur oxide removal is described.  The feed gas stream is passed horizontally through a first moving bed of treating parti-cles, which trap fine particles entrained in the gas stream.  The treating particles of the bed also are effective in removing sulfur oxides by reaction with the sulfur oxides.  The effluent of the first moving bed is passed through an upper second moving bed of fresh treating particles.  Preferably the concentration of sulfur dioxide in the effluent of the first bed is monitored to control either, and possibly both, the rate at which gas bypasses the second bed or the rate at which the treating particles are transferred from the second to the first beds.

Abstract: ABSTRACT         Liquefying of pulverulent batch materials (e.g., glass batch) is carried out in two stages.  The first stage utilizes extended gas/solid contact to heat the materials to an intermediate temperature, and may recover waste heat.  The second stage rapidly liquefies the material in a cavity lined with the batch material, and may employ substantially nitrogen-free heat sources.  Another aspect involves maintaining a wet condition in the first stage to entrap particulates.
