Abstract: ABSTRACT OF THE DISCLOSURE:              A process for the electrodeposition of metals, especially  zinc,  on  to  metal  strip,  particularly  steel strip, from an aqueous solution of metal salts. The process uses  high  relative  flow  velocities  between  electrolyte and strip and electrolyte and anodes, the metal strip being introduced vertically into the electrolyte,  turned around and led vertically out of the electrolyte.  A process of this  nature should enable  high current  densities  to be employed,  including in vertical cells in which the metal strip,  in  particular  steel  strip,  is  passed  vertically through  the  electrolyte,  and permit  even relative  flows between the metal strip and the electrolyte, thus producing even deposition conditions for the parts of the metal strip entering and leaving the cell. The electrolyte is forced to flow against the direction of strip travel throughout the section between the anodes and the metal strip.  The equipment envisaged  for carrying out  the process is de-signed so that the electrolytic cell is fitted with shaft-shaped sections  for the strip entrance and exit,  within which sections  the anodes  are arranged parallel to each other and to the metal strip, and the sections are connect-ed by a communicating lower part of the cell, and the top of the section for the strip entrance is set lower than the top of the section for the strip exit by the dimension .DELTA. h.

Abstract: ABSTRACT OF THE INVENTION     A process is disclosed for the production of 6-hydroxynicotinic acid  by biotechnological methods.   Nicotinic acid  is enzymatically hydroxylated in the presence of an equivalent quantity   of magnesium or barium ions with the help of a nicotinic acid-hydroxylating microorganism.         The resultant magnesium or barium salt of the  6-hydroxy-nicotinic acid is separated from the reaction mixture.          Then the 6-hydroxynicotinic acid is freed from the separated salts.  Examples of the microorganism are those of the genus    Pseudomonas,  Bacillus  or  Achromobacter,  for example,  Achromobacter  xylosoxydans.    Preferably  the enzymatic hydroxylation is carried out at 20° to 40°C. and a pH of 5.5 to 9.0 under aerobic conditions.

Abstract: ABSTRACT          Method of Pouring a Metallic Melt Molten metal is poured from an intermediate vessel 1 into an ingot mound 5 via a sliding gate valve 2 whose sliding plate 6 is moved in the opening or closing direction to maintain the level of the melt in the mould at a predetermined level 9.  If there is a partial blockage of the flow passage 3,4, as indicated by the sliding plate 6 performing an opening movement the sliding plate is first moved in the closing direction to throttle the flow of metal through it and thereby reduce the metal level in the mould and is then substantially fully opened to produce a surge of metal through the flow passage to remove the obstruction.  Thereafter the valve is again controlled in response to the level of the metal within the mould.

Abstract: CONVEYOR     ABSTRACT     There is provided a self-propelled conveyor for use in mining operations having an endless revolving conveyor strand driven in its longitudinal direction by intermediate drives and guided on a conveyor frame which consists of segments multi directionally pivotally connected to one another along the central longitudinal axis of the conveyor.  The conveyor frame has downwardly extendible support elements which, for the conveying operation, lift the conveyor strand reversing in the lower stringer from the ground when the support elements are extended.  For the transporting operation, the support elements are retracted so as to permit the strand to lie on the ground.          Between the segments of the conveyor frame disposed in the front region of the conveyor there are steering cylinders by means of which the angle between these segments can be adjusted so as to direct the longitudinal direction of the conveyor.

Abstract: ENHANCED PRESSURE SWING ADSORPTION PROCESSING               Abstract of the Invention A feed gas is passed to a pressure swing adsorption system, each bed of which undergoes a processing cycle that includes (1) pressurization (2) copurge at upper adsorption pressure, (3) countercurrent depressurization, including, in some embodiments, evacuation to a lower subatmospheric desorption pressure.  By recycling effluent gas released upon copurge and countercurrent depressurization for use in the pressurization or the copurge step, the more readily adsorbable component of the feed gas is advantageously recovered at high purity and at high recovery levels.  Enriched less readily adsorbable component is also recoverable as coproduct effluent at relatively high recovery levels.  The process can be advantageously employed for the separation and recovery of product nitrogen from air.

Abstract: ABSTRACT Inorganic metal oxides having high surface area and pore volume are prepared by spray drying.  The admixture which is spray dried to yield the metal oxides is produced from reactants comprising at least one hydrolyzable metal compound, a sufficient amount of water to at least partially hydrolyze the metal compound and an organic solvent.  The admixture is supplied as a plurality of droplets to a reaction zone operated under conditions of temperature and pressure below the criti-cal temperature and pressure of the reactants but suffi-cient to produce a product comprising metal oxide powders and a gas comprising organic solvent vapors. The powders are separated from the gas in a known fashion and collected.  Spray drying of non-aqueous systems unexpectedly produces metal oxides having properties generally intermediate conventionally produced oxides and aerogels.

Abstract: PROCESS AND APPARATUS FOR APPLYING CHILLED   ELECTROSTATICALLY CHARGED PARTICLES TO  THE SURFACE OF A LARGE METAL ARTICLE     ABSTRACT OF THE DISCLOSURE      The  process  described herein comprises the application  of chilled  particles  such  as  polytetrafluoroethylene   generally marketed  under  the trade mark  "TEFLON",  graphite,  molybdenum sulfite,  boron nitride, etc., to a metal surface having crevices or pores therein.   With the metal heated to expand the  crevices or  pores  and  the  particles  chilled  to  contract  them,  the particles  will be locked into the pores when both the metal  and the  particles come to equilibrium temperature with the particles thereby expanding  and  the  pores  contracting.    The  process described  herein is directed to such an application  of  chilled particles  to  expanded pores in large metal objects such as  for example,  large rolls.   The large object is rotated on it linear axis  while maintained at the desired raised temperature and  the particles are given an electrostatic charge and chilled prior  to their application to the metal surface.

Abstract: PRESSURE-RESPONSIVE DEVICE     Abstract Electrical signals are produced by a pressure-responsive device, such signals being indicative of the position of locally applied pressure.          The device comprises a position sensor assembly which comprises a composite layer medium including electrically conductive magnetic particles (e.g. 34) in a nonconductive matrix material (e.g. 35).  The medium is sandwiched between contact assemblies (e.g. 71).  The particles are aligned into chains extending across the thickness of the layer, and chains include a non-conductive gap )e.g. an air space or a nonconducting layer at least on particles nearest the contact assemblies) which is bridged upon application of sufficient pressure.  The medium is sandwiched between sheet electrodes, and the resulting assembly may be transparent as is advantageous in writing pad and touch-sensitive screen applications.  The pressure-responsive device is suitable, e.g., as an input device in graphics information systems, in combination with transmission and display facilities.
