Abstract: Abstract of the Disclosure Disclosed is a transportation device with an electrodynamic suspension, comprising a motor system, a suspension system, and a transverse stabilization system, the system being provided with exciting coils of the motor, levitation and transverse stabiliza-tion, arranged on a vehicle, and with a three-phase armature wind-ing mounted horizontally along a track bed and consisting of acti-ve portions formed as plates up to one third of the pole pitch of the armature winding in width, and of end portions formed in two layers and made as rectangular plates mounted parallel to the track axis. The end portions of the three-phase armature winding are used as reactive buses of transverse stabilization. At least one layer of the end portions is mounted parallel to the planes of the exciting coils of transverse stabilization. The proposed device requires less expenses in its manufacture and assembling and has a higher operating reliability as compared to the known transportation devices.

Abstract: METHOD FOR BRIGHTENING NATURAL CALCITIC ORES                             Abstract of Disclosure A method is disclosed for processing a natural calcitic ore to yield a finely divided calcium carbonate particulate of very high brightness characteristics.  The natural calcitic ore is initially coarse-milled to produce a product wherein no more than 5% by weight of the particulate is + 325 mesh, and no more than 35% by weight of the particles are of less than 2 microns E.S.D.  This coarse-milled product is then subjected as an aqueous slurry containing less than 40% and preferably less than 30% solids by weight, to a froth flotation, which separates with the froth the relatively coarse colorbodies liberated in the initial grinding.  Preferable compositions for use in the froth flotation comprise the salt derivatives of 1-hydroxy-ethyl-2-alkyl-imidazolines, with such compounds being utilized in admixture with a neutral aliphatic hydrocarbon.  The purified underflow from the flotation step is dewatered to at least 60% solids by weight, and is wet-milled, as for example in a sand mill, to yield an output product wherein at least 80% by weight of the resultant particulate has an E.S.D. of less than 2 microns, the product being further characterized by a brightness of at least 94 on the G.E. scale.

Abstract: BUILDING CONSTRUCTION             Abstract of the Disclosure A concrete building is constructed by initi-ally forming a generally circular concrete pad.  A spherical or slightly more than hemispherical plastic mold is then erected on the concrete pad with a central post extending axially out the central top of the mold. Barbed wire is then wrapped around the mold and wire mesh is subsequently wrapped around the mold on top of the barbed wire, with the barbed wire serving to space the reinforcing wire mesh away from the surface of the mold.  Concrete is then applied to the outside of the mold starting at the bottom of the mold adjacent the concrete pad and moving helically up the surface of the mold while laying concrete around the mold in strips. The apparatus for applying the concrete includes a frame mounted on wheels and pivoted on the post extending out of the top of the mold and being curved to follow the exterior surface of the mold.  Mounted on the frame is a hopper arrangement for feeding concrete against the mold and for automatically smoothing it into place on the outer surface of the mold with the barbed wire and the wire mesh concrete reinforcing being embedded in the two inch thick layer of concrete.  A motor is provided for feeding the hopper and concrete dis-pensing and smoothing apparatus up the movable frame as the frame is rotated around the surface of the mold, to form the exterior of a concrete building.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention provides an essentially inorganic, sintered, monolithic hollow fiber characterized by having a radially anisotropic internal void volume wall structure.          Processes for the production of such fibers are also disclosed.  The hollow fibers of this invention are useful in many fields, such as fluid separations, fuel cells and catalysis, and are capable of withstanding conditions to which they may be subjected during, for example, a separation operation, while providing adequate selective separation of the fluid together with a suffi-ciently high flux. The fibers overcome the disadvantage of providing separation membranes which exhibit adequately high selective separation, but undesirably low fluxes and thus requiring such large separating membrane surface area that the large scale commercial use of these membranes is not economically feasible.

Abstract: WATER TREATMENT DEVICE             ABSTRACT OF THE DISCLOSURE      A device for the magnetic treatment of water and other liquids, having a pair of concentric tubular casings which are spaced from each other so as to form an annular treatment chamber.  The inner casing contains an elongated magnet having two or more longitudinally spaced poles, and the outer casing is made of a magnetic material which serves to concentrate the magnetic lines of force within the annular chamber.  The inner casing is supported within the outer casing by means of elastic, non-magnetic sleeves which are positioned over opposite ends of the inner casing and compressed between it and the inner surface of the outer casing so that the treatment chamber is rendered fluid-tight and the inner casing and magnet are prevented from shifting longitudi-nally with respect to the outer casing.     The device is manufactured by pressing resilient end caps on opposite ends of the magnet and pressing this assembly into the inner casing, inserting the inner casing in the outer casing and then wedging the sleeves between them.

Abstract: ABSTRACT     Relative humidity within a machine enclosure is con-trolled by means of a desiccant and a circulatory breather flow through the enclosure walls.  The desiccant absorbs moisture during power off periods to keep the relative humidity down.  During power on periods the enclosure temp-erature rises which drives off the absorbed moisture from the desiccant.  Operation of the machine also creates a pressure differential between two breather orifices in the enclosure walls so that there is a circulatory exchange of air between the enclosure and atmosphere.  If the desiccant has absorbed a significant amount of moisture during power off periods, the moisture concentration within the enclosure will exceed that outside and there will be a net expulsion of moisture to partially recharge the desiccant.

Abstract: ELECTRO-MAGNETIC PRINT HAMMER         Abstract of the Disclosure An electro-magnetic print hammer comprises a single magnetic hammer element in which an impact mass is coupled to a pivotted armature by flexible stem.  The hammer-stem has (N+1/2) periods of oscillation at its resonant frequency during the free flight time of the hammer mass.  A permanent magnet with a strong magnetic force which decays rapidly with distance holds the hammer element fixed upon motion of the armature until the arma-ture torque exceeds the magnet holding force to cause -the hammer mass to break loose with a snap action.  Stop means prevents armature impacts with the operating pole piece of a stator core.  The visco-elasticity of the armature stop matches the rebound characteristics of the print medium when impacted by the hammer mass.

Abstract: ABSTRACT OF THE DISCLOSURE An improved building, e.g., a greenhouse structure, is provided herein.  It consists of an enclosure having a pair of spaced-apart walls, e.g., an outer light transparent covering and an inner light transparent membrane spaced apart from the outer covering.  A fan is provided for charging the space between the covering and the membrane with air, having a dew point so selected that it will not allow condensation to take place, e.g., outdoor air, under pressure. An insulating layer is disposed in the pressurized air space between the outer covering and the inner membrane. The insulating layer includes an insulating blanket disposed between the outer covering and the inner membrane, and is positively movable between an extended covering position and a retracted stored position.  Operating structure is connected to a leading edge of the blanket and this structure is adapted to move the leading edge from its retracted stored position to its extended covering position.  Cooperative structure is provided opera-tively associated with the trailing portion of the blanket.  This struc-ture is adapted to draw the blanket from its extended covering position to its retracted stored position.  This provides a system in which heat loss from within the structure is minimized at night and yet does not result in excessive condensation within the structure.
