Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for the production of a stack of etched, patterned metal foils for component elements, such as fluid plates and nozzle plates, is disclosed.  Individual patterned foils are cut free from a mat having a group of patterned foils and also edge foils.  The patterned foils are examined and unwanted foils together with the edge foils are discarded.  The approved foils are individually stacked at stacking positions in a stacking station.  A number of foil stacks corresponds to the number of individual patterned foils in the mat with the patterned foils being placed on the foil stacks in correspondence with their arrangement in the mat. Additional patterned foils from additional mats are stacked onto the individual foil stacks until a counter for each of the stacks determines that a pre-determined number of stacked foils has occurred.  The stack is removed and a new stack is begun until the counter again arrives at the predetermined number of foils for a given stack.

Abstract: METHOD OF MAKING A MOLD OR PATTERN OR CASTING    FOR A TURBINE WHEEL OR A NOZZLE            Abstxact of the Disclosure A method is presented for forming a rotatable tur-bine wheel or nozzle having one continuous and regular series of blades extending around its periphery with a uniform pitch between blades and in which all such blades are bent in one circumferential direction and adjacent blades overlap each other in a circumferential direction so that the wheel cannot be made in a simple two part mold separating at right angles to a parting line.  The method comprises separately molding two wheel portions of the same diameter as the finished turbine wheel or nozzle, each having a series of continuous and regular blades around its periphery with a uniform pitch between the blades which is exactly twice the pitch of the blades in the finished wheel.  In such a wheel portion the adjacent blades do not overlap each other.  Two wheel portions are then assem-bled by placing the two wheel portlons together in such a mutual position that the blades of the two portions form the one continuous and regular series of blades which comprises the turbine wheel or nozzle.  The turbine wheel or nozzle itself, made in such a manner, is also part of the invention.

Abstract: COLOR IMAGING ARRAY            ABSTRACT OF THE DISCLOSURE         Light responsive elements of a color imaging array are arranged in basic groupings of four aligned ele-ments, which groupings included two luminance-responsive elements that alternate with individual elements for two other basic colors.  These groupings are repeated along a line and are shifted by one element in each adjacent line.          As a result of intermixing color-responsive elements in this way, high-spatial-frequency luminance sampling is achieved for all directions on the array and closely re-peated patterns of elements are achieved for all three basic colors in both fields of the array (here assuming a two-field interlaced readout array).  Because closely repeated sampling occurs for all colors in both fields of such an array, the field-to-field color flicker, that can occur when intermixed color sampling is attempted using an interlaced-readout imaging array, is avoided.

Abstract: ABSTRACT OF THE DISCLOSURE          Fluidized beds of iron in alpha-alumina solid solution catalysts useful in converting feed gas mixtures of ethane, oxygen and hydrogen chloride to vinyl chloride and ethylene are maintained at peak efficiency by on-stream addition of one or more of the catalyst precursor materials such as an iron compound and alpha-alumina particles. Iron lost by the catalyst is replaced by on-stream addition of an iron compound to regenerate the catalyst.  Overhead losses of catalyst as fines formed by attrition are replaced by on-stream addition of alpha-alumina particles which are converted to catalyst particles by the simultaneous or subsequent addition of the catalyst metal precursor compounds.  The presence of an atmosphere of the feed gases appears to lower the threshold temperature at which iron cations dissolve or diffuse into the alpha-alumina host lattice replacing the alumina cations of the host lattice.  To form solid solutions of this type in an oxygen atmosphere require extended calcination of 1100° to 1300°C but form easily at temparatures of 500 to 650°C in an atmosphere of the feed gases.

Abstract: ABSTRACT OF THE DISCLOSURE                 A nonwoven fabric-like material having a unique combination of strength, absorbency and hand consists essentially of an air-formed matrix of thermoplastic polymer microfibers having an average fiber diameter of less than about 10 microns, and a multiplicity of individualized wood pulp fibers disposed throughout the matrix of microfibers and engaging at least some of the microfibers to space the microfibers apart from each other.  The wood pulp fibers are interconnected by and held captive within the matrix of microfibers by mechanical entanglement of the microfibers with the wood pulp fibers, the mechanical entanglement and interconnection of the microfibers and wood pulp fibers alone forming a coherent integrated fibrous structure.  The coherent integrated fibrous structure may be formed by the microfibers and wood pulp fibers without any adhesive, molecular or hydrogen bonds between the two different types of fibers.  The wood pulp  fibers are preferably distributed uniformly throughout the matrix of microfibers to provide a homogeneous material.       The material is formed by initially forming a secondary air stream containing the wood pulp fibers, merging the primary and secondary streams under turbulent conditions to form an integrated air stream containing a thorough mixture of the microfibers and wood pulp fibers, and then directing the integrated air stream onto, a forming surface to air form the fabric-like material. The microfibers are in a soft ??ascent condition at an elevated temperature when they are turbulently mixed with the wood pulp fibers in air.

Abstract: TITLE           A METHOD OF MAKING A CELLULAR BODY FROM A HIGH SILICA BOROSILICATE COMPOSITION                  ABSTRACT OF THE DISCLOSURE           An intimate mixture of an amorphous silica (pref-erably an amorphous, precipitated hydrated silica) potassium oxide, boric oxide, alumina and a cellulating agent is pre-pared.  The intimate mixture is thereafter subjected to a temperature of between about 1390°C to 1450°C for a sufficient period of time to coalesce the mixture and gasify the cel-lulating agent and form a cellular body having a substantially uniform cell structure.  In one embodiment the intimate mixture is prepared by first forming a slurry of the constituents and thereafter drying the slurry to form aggregates.  The dried aggregates are thereafter comminuted if necessary to a suitable size to form a pulverulent batch.  The pulverulent batch is subjected to a cellulating temperature in a cellulating furnace and forms a foam-like mass.  The foam-like mass is comminuted to a suitable size to form a precellulated material.  The pre-cellulated material is thereafter intimately mixed with additional cellulating agent and pulverulent batch in pre-selected proportions and subjected to cellulating temperatures in the cellulating furnace where the constituents coalesce and gasify the cellulating agent to form a cellular body having a substantially uniform cell structure.  In another embodiment alumina, boric oxide, an alkali metal salt and a cellulating agent are comminuted and intimately mixed in a ball mill to form a first mixture.  Thereafter, amorphous silica (preferably an amorphous, precipitated hydrated silica) is added to the first mixture to form a second mixture or batch that contains more than 80% by weight amorphous silica.  The second mixture is milled in the ball mill and thereafter the second mixture is subjected to a temperature sufficient to coalesce the second mixture and gasify the cellulating agent to form a cellular body having a substantially uniform cell structure. A preselected portion of the trimmings from the cellular body may be added to and comminuted with the first mixture before the amorphous silica is added to the first mixture to form the second mixture.

Abstract: ABSTRACT OF DISCLOSURE   A device as described whereby the concentration of a gas such as alcohol vapour can be measured using radiation absorption techniques in a pair of chambers.  The chambers are elongated tubes, the first having a window at one end through which infra red radiation can pass with an optical reflector at the two ends of each tube so that radiation from a source and focused  by an ellipsoidal reflector passes through the first tube in both directions and thence through the second.  The reflected radiation leaves the second tube through a second window in the side of the tube, from where it passes to a detector.  Passing the radiation in series through two or more parallel arranged chambers, conveniently located within a common housing increases the sensitivity.
