Filed: 1985-08-20
Granted: 1989-10-03
Abstract: ABSTRACT OF THE DISCLOSURE:            A ceramic body having continuous three-dimensional through holes can be employed as a filter for filtration of non-metallic inclusions in a molten metal and as a porous plug for introducing a gaseous medium for flotation of such non-metallic inclusions on the surface of a molten metal bath. The ceramic body is prepared by placing an organic body having a three-dimensional construction in a casting mold, pouring a slip of a ceramic material into the mold, and after drying,  baking the molded body for decomposition of the organic porous body.   The ceramic body thus provided, has within it,  three-dimensionally interconnected through holes and has a high mechanical strength.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a demodulation circuit for use in a heterodyne receiver for stably demodulating a carrier-suppressed double-sideband signal such as a 2-phase or phase PSK signal.  The demodulation circuit comprises a reference oscillator oscillating at a frequency corresponding to an intermediate frequency, and the frequency difference between the reference frequency and the input frequency is detected by a costas loop, a signal indicative of the frequency difference being fed back to a local oscillator through a loop filter thereby stabilizing the intermediate frequency.

Abstract: Abstract A vibratory particle separation apparatus of the type having at least two plateau conveying surface interrupted by a drop-out opening.  A composite mixture is conveyed by a vibrating action beyond the upper pla-teau and over a foraminous section in the upper plateau adjacent the drop-out opening.  Air is directed upwardly through the foraminous section to break apart the compo-site mixture, and an air supply is also directed angular-ly in relationship to the plane of the upper plateau to further break apart the composite mixture and to propel particles of a predetermined density and/or dimension to the landing area on the second level.  In another aspect of the invention, the landing area is adjustable angular-ly with respect to the plane of the upper plateau of the conveying surface and is translatable to constrict or enlarge the dimensions of the drop-out opening.  The par-ticles passing through the drop-out opening and not in-tercepted by the landing area exit the system.

Abstract: Abstract of the Disclosure A trioxane polymer is continuously produced with a continuous stirring-mixing apparatus which comprises two parallel rotational shafts, a number of paddles mounted on each rotational shaft and a barrel having an inside wall surface along the cir-cular surface traced by the respective paddles, as they rotate, the barrel having a cross-section in the shape of two circles concentric with the two rotational shafts, which overlap each other.  The apparatus is provided with a temperature controlling jacket.  In the apparatus a mixture of trioxane, catalyzer, other copolymerizable comonomers, as the case may be, and additives is continuously fed in through a material supply port located at one end thereof, then, the material mixture is subjected to a polymeri-zation or copolymerization reaction, while being stirred by turning the aforementioned rotational shafts in opposite directions to each other and, thereafter, the polymers or copolymers of trioxane are taken out as fine granules through a discharge port located at the other end thereof.  The method is characterized in that one set or two or more sets of paddles of a sectional shape which meet the requirement that when a pair of paddles facing each other are turned in different directions around their rotational axes, the clearance between them is kept to less than 3/100 of the barrel ID, the paddles being mounted on each shaft, adjoining each other, and the different direction turning is made in a state such that the clearance between the farthest part from the rotational axis of said paddle and the inside wall of the barrel is always less than 3/100 of the barrel ID.

Abstract: Abstract A variable reluctance motor having tapered stator teeth and more rotor teeth than stator teeth.  The width of the stator and rotor teeth provides a relatively high rotor tooth ratio and a relatively low stator tooth ratio.  With this configuration the motor has very low torque ripple.  Magnetic saturation is limited to the tips of the stator teeth, so the motor can be operated at current levels above the saturation point, producing a linear torque to current function and high output torque.

Abstract: ABSTRACT          A process for making additive multilayer circuit boards uses separately designed and fabricated composite structures each consisting of a patterned conductive metal foil supported by a photo-processible insulating film.  The composite is bonded foil pattern side down to the substrate or pre-existing multilayer structure and selected areas of the insulating film are removed down to underlying metal sites for electroless plating.  All of the apertures in the insulating film are then electrolessly plated full of metal flush to the upper surface.  Additional patterned composites are applied and plated up as desired to create blind vias and new conductor patterns layer by layer.  In an alternate process a foil clad composite is bonded to an existing substrate foil side up.  The insulating layer is selectively etched through windows photoetched in the foil layer. The voids in the insulator layer expose copper sites on the underlying composite.  The voids are plated full of metal to form vias and the foil layer is photoetched to make a conductor pattern.  The process is repeated to make a multilayer PWB.

Abstract: Abstract of the Disclosure A telephone system allows a user to provide new services to terminations in a telephone network.  A server having program sequences for controlling its operation connects the terminations and the telephone network.  Using certain of its program sequences, the server monitors the occurrence of a request event at one of the terminations.  A processor, distinct from the server, controls the server by accessing a directly accessible database to extract a state transition rule to provide control information corresponding to the response event.  Information is returned to the terminations in response to the control information.  The database storing the state transition rules is directly accessible by the user for changing the state transition rules to modify the services without changing the program sequences of the server.  State transition rules within the database may be inserted, deleted or modified using conventional database management techniques.
