Abstract: RECOVERY OF VANADIUM VALUES                     ABSTRACT OF THE DISCLOSURE   Vanadium values such as those in the form of vanadium pentoxide may be recovered from vanadium-containing materials by leaching the vanadium-containing material with caustic and thereafter precipitating insoluble salts of vanadium with an ammonium-containing compound followed by sepa-ration and recovery.  After suitable stripping of ammonia from the lean leach solution, said solution may be recycled to the leach step.  The recovery of the vanadium values is enhanced by effecting the precipitation step in the presence of carbon dioxide which maintains the pH of the solution in the optimum range.

Abstract: ABSTRACT OF THE DISCLOSURE An improved process for the production of catalysts comprised of a metal hydrogenation component, or components, composited with high pore volume alumina, with pores of narrow pore size distribution, wherein macropore volume is drastically reduced by improved extrusion techniques.  An alumina hydrogel paste is extruded through a die to form spaghetti-like extrudate shapes by app-lication of sufficient torque, suitably form about 25 to about 55 inch-pounds, preferably from about 40 to about 50 inch-pounds, to eliminate much of the macropore volume, i.e., pores greater than 400.ANG., which greatly improves the activity maintenance of the catalyst.  The extrudates can, if desired, be shapedinto other forms, suitably spheres.  The process of the present invention em-bodies a technique for increasing the intrinsic activity of these and other catalysts by special impregnation and rying techniques which provides better dispersion of the metal hydrogenation component, or components, throughout the catalyst.

Title: Method of burning solid fuel in a closed firebox and  a stove for carrying out the method
Inventor: LARSSON HUGO

Abstract: Luftkonditionering AB        A method of burning solid fuel in a closed firebox and a stove for carrying out the method Abstract In a method of burning solid fuel in a closed firebox for heating circulating air the firebox is provided with an air-supply passage and is separated from the surroundings.  The rate of combustion is controlled by means of at least one damper arranged in the air-supply passage.  The temperature of the heated . circulating air is limited to a prescribed maximum value.  One or more control means, such as a thermostat, time-relay or the like controls the movement of the damper between either a substantially fully open position and a substantially fully closed position, in which the supply of air to the firebox is substantially cut off.          In the closed position of the damper the combustion will practically cease but the fuel shall maintain a sufficiently high temperature for the combustion process to recommence when the damper is reopened.          At the same time a desired given temperature is maintained in a space heated by the circulating air or an object, such as an oven, a hot-plate, a hot-water producing device or the like, heated by the hot flue gases.  During those periods of time when the damper is closed the temperature of the fuel is maintained by limiting the amount of heat given from the firebox. Thus, the circulation of air around said firebox can be reduced.        A thermo-electric generator may co-act with one or more electrical thermostats in a manner such that when the firebox is cold the thermo-electric generator does not produce energy and then the damper will be held fully open.  However, when the temperature of the firebox, and then the output from the generator, reaches a specific desired value the damper will be closed via setting devices, provided that no thermostat will call for heat.        The invention also concerns a stove for burning solid fuel by the above method.  The stove has an air-supply passage (13) adapted for so-called balanced draft during heat exchange with the flue-gas duct extending from the firebox.  The circulation air is drawn in by means of a fan arranged in the neighbourhood of the lower part of the stove.

Abstract: Abstract of the Disclosure In a control circuit for igniting thyristors and reporting back thereon, which is controlled by a pulse-control telegram containing double and single pulses produced in a central system control, the double pulse initiates the ignition phase and the single pulses  initiate individual monitoring and measuring phases of the thyristor.   The pulses of the pulse-control telegram are passed to a first AND- element and to a monostable flip-flop.  The output pulses therefrom  actuate a second AND-element and a further input to the first AND-element.  The output signals therefrom set the control counter to the ignition position.  A signal, released by the control counter in its last position, is passed to a third AND-element and, inverted, to a further input to the second AND-element. The output signals therefrom actuate the timing input to the control counter.  The inverted output pulses from the flip-flop are passed to a further input to the third AND-element, the output signals from which constitute the report for igniting the thyristor.

Abstract: ABSTRACT:           A word-organized, content-addressable memory comprises per word location a validity indicator, hav-ing a position "valid" and a position "invalid", and a correspondence indicator.  The following functions can be performed: a) associative searching and reading of the content of a word for which correspondence occurs (R); b) reading the next word in sequence of words for which correspondence occurs (SR); c) loading a mask word in the mask register (LM); d) selective invalidating of the content of one or more predetermined word locations (CPM); e) writing in an empty word location, i.e. a location not having a valid data content (WFP); f) writing data in a number of selective bit positions of one or more words for which correspondence occurs (WP).          There is also provided a mask register whose data activate the comparisons as well as the outputting of data for which no comparison has taken place.          As a result of such an organization, a very versatile use is realised for a comparatively inexpens-ive memory.  In a memory of this kind, constructed as an integrated circuit, moreover, only a small number of connections are required per number of bit positions.
