Abstract: PRODUCTION OF SPONGY CERAMIC MATERIAL            ABSTRACT OF THE DISCLOSURE:    Spongy ceramic material supporting exhaust gas decontamination catalysts is produced. Loosely aggre-gated polystyrene spheroids are joined together across their contact surface to a spheroskeleton having hollow spaces which are filled with an aqueous suspension of ceramic material. More particularly, use is made of hollow foamed polystyrene spheroids which are connect-ed together to a sphero-skeleton by plasticizing their surface areas. The hollow spaces inside the spheroske-leton are filled with the aqueous suspension of cera-mic material and the skeleton is dried at 20 - 95°C. The dry material is freed from the polystyrene spheroids and the ceramic skeleton is calcined at 1000- 1500°C.

Abstract: ABSTRACT OF THE DISCLOSURE       This invention controls the application of a parison to a core rod in the cavity of the injection mold of injec-tion blow molding apparatus.  The invention is particularly useful for core rods that include a balloon which covers the outside surface of the core rod and over which the parison is applied.  Elastomer material of which the bal-loon is made is eventually eroded by the hot blast of plastic injection against the end of the core rod in the conventional manner.  This invention covers most of the core rod with a protecting metal tube in the mold cavity and applies the plastic as a rolling wave instead of a blast impact.

Abstract: A B S T R A C T         An electric power coupler for use with first and second door members relatively movable along a predetermined path toward and away from substantial abutment has a first frame mounted on the first door member.  An inner pair and an outer pair of first frame electrical connectors are mounted on the first frame in a recess therein having a lateral opening in the direction of the path.  The first connectors have exposed surfaces parallel to the path. At least some of the connectors are resilient in a direction normal to the path.  The second frame is mounted on the second door member and supports a plunger for movement in a direction normal to the path.  The plunger is spring urged to project, and cam surfaces on the first frame and the second frame cause the plunger to retract.  The plunger has opposite walls partly defining a chamber therein having a lateral aperture confronting the recessed opening.  An inner pair and an outer pair of second frame electrical connectors are respectively disposed on the opposite walls.  The second connectors have exposed surfaces parallel to the path and in position to engage the exposed surfaces of the first connectors.

Abstract: A B S T R A C T        A rock boring assembly for producing a straight hole for use in a drill string above a pilot boring bit of predetermined diameter smaller than the desired final hole size.  The boring assembly comprises a small conical boring bit and a larger Conical boring bit, the conical boring bits mounted on lower and upper ends of an elongated spacer, respectively, and the major effective cutting diameters of each of the conical boring bits being at least 10% greater than the minor effective cutting diameter of the respective bit.  The spacer has a cross-section resistant to bending and spaces the conical boring bits apart a distance at least 5 times the major cutting diameter of the small conical boring bit, thereby spacing the pivot points provided by the two conical boring bits to limit bodily angular deflection of the assembly and providing a substantial moment arm to resist lateral forces applied to the assembly by the pilot bit and drill string. The spacing between the conical bits is loss than about 20 times the major cutting diameter of the lower conical boring bit to enable the spacer to act as a bend-resistant beam to resist angular deflection of the axis of either of the conical boring bits relative to the other when it receives uneven lateral force due to non-uniformity of cutting conditions about the circumference or the bit.  Advantageously the boring bits also are self-advancing and feature skewed rollers.

Abstract: POWDER FILLING MACHINE            ABSTRACT    A composite measure of varying capacity, composed of supply-ing-apparture of straight cylinder and an inside measure telescop-ically inserted into the apparture and having a hollow of frusto-conical section, is employed in order to improve accomodation of the known conventional capacity type rotary powder filling machine, to powder of varying bulk density.    A turntable which receives the supplying-apparture, superim-poses over another turntable which holds the inside measure, and the distance between the both, is adjustable during the operation in accordance with the variance in the bulk density.  The height of the container transferring path is also adjustable simultaneous-ly with that of the second turntable. Spouting of compressed-air through an annular nozzle the diameter of which approximates to that of the apparture as a flow parallel to their inside wall is effected to blow off remaining powder in the measure and clean the same when the nozzle is dis-posed on the apparture.    Evacuation for removing air from an empty or partly filled container is made through an annular suction inlet capable of suctioning the air as a flow parallel to the inside wall of the container.

Abstract: Abstract of the Disclosure This specification discloses a process and a culture composition for growth of an alga and synthesis of biopolymer by the alga.  The process involves growth of the alga and concomitant synthesis of the biopolymer in an aqueous culture containing as a source of phosphate for said alga dibasic sodium or dibasic potassium phosphate. The nitrogen source can be sodium nitrate or urea.  Control of the pH of the culture is effected by injecting a mixture of carbon dioxide and air into the culture during growth of the alga and synthesis of the biopolymer.  The carbon dioxide also serves as a source of carbon for growth of the alga and synthesis of the biopolymer and provides agitation/mixing within the culture chamber.  Preferably, the mixture of carbon dioxide and air is injected continuously into the culture during the entire growth period of the alga.
