Patent CA-1061388-A (CA)

Abstract: ABSTRACT               The disclosure concerns a radial bearing arrangement for a large diameter rotor wherein the rotor carries an annular surfache in a peripheral region spaced radially from the axis which cooperates with a series of bearing means mounted in a foundation.  The bearing means provide reactions in a limited number of main supporting direction  and act collectively to restrain the rotor against movement in all radial directions.     Not more than two of the bearing means provide positive, non-yielding restraint in those main directions, whereas the other bearing means have radially displaceable bearing shoes and furnish yielding holding forces.  The arrangement may include one type of yielding bearing means which furnishes a reaction which varies with displacement and affords a centering action, and/or a second type which furnishes a constant reaction during slow displacements and an increased reaction during rapid dis-placement, and thus affords damping action.  In cases where the rotor axis is not vertical, a type of bearing means, which affords a constant reaction regardless of displacement, may be employed to carry the weight of the rotor.

Abstract: ABSTRACT OF THE DISCLOSURE:         The invention is concerned with a process for the production of polyvinyl chloride by suspension polymerization of vinyl chloride monomer, alone or in mixture with other copolymerizable monomers, in a medium consisting essentially of water and containing a water-soluble suspending agent.  The process of the invention is characterized in that the polymeriza-tion is conducted in the presence of polyvinyl acetate having an average molecular weight between 10,000 and 30,000, and being partially hydrolyzed so that its saponification number is between 300 and 600.  The invention enable  one to produce a product having high porosity and high uniformity in the ganulo-metric distribution of the particles, which permits almost complete removal of residual monomer in the final stripping stage.

Abstract: ABSTRACT OF THE DISCLOSURE       A stabilized slurry of Beta-type alumina powder, a method of stabilizing said slurry of Beta-type alumina and a method of pro-ducing minute, spherical agglomerates of said Beta-type alumina by spray drying said stabilized slurry.  Said stabilized slurry exhibits a prolonged viscosity sufficiently low to accomodate spray drying techniques to produce said minute spherical agglomerates capable of rapid filling in ceramic forming pressing machinery.  Beta-type alumina powder is mixed with water and other conventional additives to form a slurry mixture.  A small amount of a polycarboxylic acid containing 3 or more carbon atoms and being capable of chelating with aluminum ion is added as a dispersing agent to inhibit any substantial increase in viscosity.  The maintenance of moderate to low viscosity permits application of such slurry to above processes for forming Beta-type alumina agglomerates which rely for formation on a low viscosity, uniformly dispersed stabilized slurry.           The invention herein described was made in the course of or under a contract or subcontract thereunder with the National Science Foundation.

Abstract: ZERO CLEARANCE FIREPLACE TYPE HEATING DEVICE                  ABSTRACT OF THE DISCLOSURE           An efficient zero clearance fireplace heating device is disclosed.  The device includes a conventional metal firebox having closeable glass doors and a flue adapted to communicate with a chimney.  The sides and bottom of the firebox are enclosed with mutally spaced metal walls to form a plurality of interconnected chambers for circulating either room air or outside air therethrough.  A portion of the circulated air is returned to the room through a vent and a portion is admitted to the firebox for combustion air.  The combustion air is initially directed across the interior surface of the glass doors to minimize blackening thereof by smoke from the fire.  Baffles may be provided between walls of the interconnected chambers to provide a labyrinthian series of passages for air circulated therethrough whereby heat is exchanged between the walls and the circulating air so that the outside surfaces of the device remain sufficiently cool to permit installation adjacent combustible structural members.

Abstract: PEDESTAL BUBBLE DOMAIN CHIP AND PROCESSES FOR MAKING SAME     Abstract of the Disclosure An improved magnetic bubble domain chip and processes for making the chip are described.  The chip is comprised of a magnetic bubble domain film in which small bubble domains can be moved, and overlying layers of metallurgy.  The layer of metallurgy closest to the bubble film is an electrically conductive layer having apertures (or recesses) therein.  This layer is patterned to provide current carrying conductors.  The next overlayer is a layer of magnetic material having in-plane magnetization which is patterned to provide the propaga-tion elements used to move the bubble domains.  In a particular embodi-ment, the magnetic layer is comprised of a magnetically soft material, such as permalloy.  The chip is characterized by the provision of insulating pedestals located in the apertures of the conductive layer. These insu-lating pedestals are located in the regions of the chip used for sensing (and/or bubble generation).  That is, they take the place of the thick conductive material in those areas of the chip.  The sensor and bubble generators are usually portions of the in-plane magnetic layer.  If the height of the insulating pedestals is the same as the height of the conductive layer, planarization is achieved and each overlayer lies in a single plane, where the planes are parallel to one another.  However, the pedestal can be of any desired height.  This chip is particularly advantageous for use with bubble domains having diameters of about 1 micron and less, since the pedestal magnetic chip can be provided by single level masking techniques in which only a single critical masking step is required.  The insulating pedestal can be formed prior to deposition of the current carrying conductive layer, or subsequent to deposition of this layer.
