Abstract: U.S. 903,635 ABSTRACT OF THE DISCLOSURE          In a coal gasification operation or similar conversion process carried out in the presence of an alkali metal - containing catalyst wherein solid particles containing alkali metal residues are produced in the gasifier or similar reaction zone, alkali metal constituents are recovered from the particles by withdrawing and passing the particles from the reaction zone to an alkali metal recovery zone in the substantial absence of molecular oxygen and treating the particles in the recovery zone with water or an aqueous solution in the substantial absence of molecular oxygen.  The solution formed by treating the particles in the recovery zone will contain water-soluble alkali metal constituents and is recycled to the conversion process where the alkali metal constituents serve as at least a portion of the alkali metal constituents which comprise the alkali metal-containing catalyst.

Abstract: 53,436 CAN/JLG                       Abstract A microorganism identification test container comprises a tray member provided with a plurality of wells.          Some of the wells are microorganism identification test wells having biochemical test media which permits growth of microorganisms with the generation of a volatile color-forming compound,  Some of the wells are negative control wells including an inhibitor which prevents color formation in the negative control wells caused by the volatile color-forming compound generated in the test wells.  Preferably a series of biochemical test media is adjacent to the corresponding negative control medium.         Comparison between the negative control wells and the test wells, after inoculation and incubation of the microorganism, indicates the presence of a particular microorganism.  Since many of the biochemical test media produce only subtle changes in response to microorganism activity, the appearance of the negative control must remain essentially unchanged or subtle changes in the biochemical test wells will not be perceived.

Abstract: RCA 74,344 SEARCH TYPE TUNING SYSTEM                ABSTRACT OF THE DISCLOSURE           A tuning system for a television receiver includes a phase locked loop (PLL) configuration and an automatic fine tuning (AFT) configuration which are selectively enabled to operate to tune the receiver to nonstandard as well as standard frequency RF carriers which may be provided by cable and master antenna systems. After the selection of a new channel, the operations of the PLL and AFT configurations are sequentially enabled by a mode control apparatus.  During the operation of the AFT configuration, an offset detector determines when the frequency of the local oscillator signal is caused to be more than a predetermined offset from its value established during the previous operation of the PLL configuration. In response, the mode control unit reestablishes the operation of the PLL configuration.  Channel selection apparatus causes a new channel to be selected after a predetermined number of alternate operating cycles of the two configurations.

Abstract: Abstract of the Disclosure The economy of production of hydrogen and sulfuric acid in a three chamber electrolysis cell in which an electrolyte flows through the intermediate chamber which is bounded by ion exchanger membranes can be improved by the provi-sion of a porous supporting framework or skeleton of graphite or of ion exchanger material against which the separators with the electrodes on them, can be pressed. The overall internal resistance of the cell can thus be reduced and its mechani-cal behavior improved.  Substantial through passage porosity is desired in the supporting structure, which may be of graphite, but porous aggregates of ion exchanger material with fixedly applied or welded on separators in the form of stacked layers or rolled mats, are preferred for the relative simplicity of their provision in practice.
