Abstract: Abstract A novel improvement in the process for the carbo-chlorination of kaolinitic ores is provided wherein the improvement comprises adding catalytic amounts of boron chloride to the carbo-chlorination step which results in the catalyzed and controlled chlorination of alumina and silica. Preferably, about 0.3 to 5.0 percent of boron chloride per volume of chlorine is added to the chlorina-tion step and in combination with from 5 to 40 percent or more of reductant carbon to provide a conjoint action wherein preferential chlorination of alumina over silica is obtained at low levels of boron chloride and reductant and total chlorination of both alumina and silica are ob-tained at high boron chloride and reductant levels.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a new compound to be used as insulatinq material, e.g. as heat and fire insulation in house construction.  The new material of the present invention is a material insulating against and thus operating in cold as well as heat, it does not cause damage at fires (i.a. no poisonous gases being developed), it does not shrink and has good adhesion, which gives a practical  ?-value that sub-stantially agrees with the theoretical one, it is environmental non-hazardous, i.e. it does not contain any poisonous substances, and it is easy to inject and in practice useful at working sites, without necessitating the use of complicated equipment.  The new material of the invention comprises a mixture of water, binder, wetting agent, water glass, mineral wool, expanded vermiculite and optionally ammonia.  The material is character-ized in that it comprises a mixture of 250-1500 parts by weight of water, 5-70 parts by weight of binder, 1-10 parts by weight of anionic or cationic wetting agent, 10-100 parts by weight of mineral wool, 30-300 parts by weight of expanded vermiculite, optionally 1-10 parts by weight of ammonia, and optionally a difficultly fusible ballast material.

Abstract: ABSTRACT OF THE DISCLOSURE     A connector pin assembly for concentrically aligning and terminating a fiber optical cable with respect to the outer dimension of the pin includes a tubular body having two ends, a longitudinal bore extending into one end of the body and a counter bore extending into the other end of the body.  The counter bore has inner walls concentric with the outer dimension of the body and communicates with the longitudinal bore.  A plurality of pin members of equal dimension are within the counter bore arranged in side-by-side relation for tangential contact with the inner walls of the counter bore, tangential contact with each other, and tangential contact with an optical fiber inserted into the central passageway defined by the pin members,  As a result, the optical fiber is held by the pin members concentri-cally with respect to the outer dimension of the tubular body.          Also disclosed is a method of terminating an optical fiber within a connector pin of the present invention and concentrically aligning the optical fiber with respect to the outer dimension of the pin.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved method of cold pressure welding a cover member to the edge of a hollow tubular member, with both mem-bers consisting of cold pressure weldable metal.  The method comprises outwardly bending the end portions of the members to provide frusto-conical interfitting flanges.  The cylindrical member is placed in a die wherein the die supports the flange on the cylindrical member.  The cover member is mounted on a circular punch wherein the punch supports the flange on the cover member.  The punch is positioned concentric with the die.          A metallic interlay is placed between the faying surfaces of the members.  The flanges and the interlay comprise the weld assembly.  The punch is axially displaced relative to the die to compress the weld assembly thereby creating an intense inter-facial flow conducive to bonding of the members in a solid phase welding bond.

Abstract: TITLE:  FLYING SPOT PATTERN STORAGE SYSTEM                  Abstract of the Disclosure A storage system is provided in which digital numbers are read into a memory by periodically sampling a pair of analog input signals and in which the memory is scanned in timed relation to the signal sampling and also in timed relation to the scanning of a cathode ray tube screen in a raster pattern, the scanning spot being bright-ened when a stored digital number is detected.         A pair of digital-to-analog converters are used both in sampling and for raster scanning.  In sampling, the outputs thereof are compared with the input signals to control analog-to-digital logic circuits and the inputs thereof are connected through multiplexers to the output of the analog-to-digital logic circuits which operate as successive approximation registers.  In raster scanning, the inputs of the digital-to-analog converters are connected to counter sections driven from a high frequency clock one being operative to develop a sawtooth signal to generate a sweep line and the other being operative at a field or frame rate.  The memory is also connected through the multi-plexers, alternately to the outputs of the analog-to-digital logic circuits and to the counters to be scanned in synchro-nism with the scanning of the screen.  The multiplexers are so switched that sampling is performed between successive sweep lines.
