Abstract: A case for carrying pole vault poles is made of an elongate flexible bag of a length approximately equal to the length of the pole vault pole or poles to be carried and a sheet of semi-rigid laterally bendable material generally coextensive with the bag and forming therewith a shell for protectively encircling the pole or poles contained within the bag. The bag is preferably of butterfly style foldable and unfoldable about a longitudinal fold line between a closed position and an open position. The sheet of semi-rigid material lies flat in the open position of the bag and is bendable about the longitudinal fold line to form a pole encircling protective shell in the closed position of the bag. The case facilitates convenient carrying of pole vault poles from place to place, for example, from track meet to track meet, and insures safe, damage free transport of pole vault poles when transported, for example, via commercial carriers.

Abstract: A high opacity, defined kaolin clay product having a relatively narrow particle size distribution, low colloidal particle content and an average particle surface area of less than about 30 square meters per gram is prepared by defining an aqueous kaolin clay slurry via controlled centrifugation to remove a substantial portion of the colloidal particles therein. Prior to being subjected to centrifugation, the aqueous kaolin clay slurry is prepared so as to improve the defining process achieved via centrifugation by first subjecting the aqueous kaolin clay suspension to scrub grinding so as to break up agglomerates into individual kaolin clay particles without substantial delamination of the kaolin clay particles.

Abstract: An axially moveable portable tool, such as a drill, and a guide for the tool are disclosed. The guide has a base with a post and a handle attached to and extending from the base. The post and handle are positioned so that a projection of the time of force applied during use to the tool grip and to the handle, both fall substantially within the base footprint. The upper extremity of the post can be provided with attachments that form parallel guide means or with angular sections that form a external guide for standard size and shaped portable tools. The portable tools can be easily attached to the post to assume a specific angle with the base and can be easily removed from it for independent use.

Abstract: The invention is to an improvement for power tool presses of the type that clamp a portable tool, such as a drill, for use as the cutting means. A commonly used base, column, support bracket, rack and pinion and actuating handle are used. The press is provided with a pressure plate that is driven by the actuating handle to drive the cutting means. The power tool is securely and accurately positioned on a guide post or by parallel adjustable guide means. A single simple lock plate holds the power tool in position on the press or releases it for removal from the press. The tool is quickly removed from and quickly and accurately repositioned in alignment on the guide and easily clamped to it.

Abstract: A guide for an axially movable hand-held tool, such as a drill, is disclosed. The guide has a base that supports a pivot assembly including a post attachment with a guide post and an angle locator, used with an adjustment shaft for angle cuts. A "U" bracket adjustably supports the post attachment on the guide base. One end of the adjustment shaft is shaped to prevent rotation while permitting reciprocation of the shaft within the "U" bracket. A handle cooperates with the adjustment shaft to clamp the pivot assembly to the "U" bracket and guide base at selected angles and is used to position and control the guide during use. A spring biases the post attachment toward one leg of the "U" bracket for angle selection, location and retention.

Abstract: Two processes and apparatus for chromatographically separating components of a volatilizable mixture on a continuous basis are described herein as specific examples of the continuous preparative chromotographic separation of unwanted volatile species from volatile product by passage through a continuous fibrous textile solid. The volatilized mixture is fed by means of a flowing carrier gas through a column or conduit containing continuous polymeric solid therein such as a fibrous textile solid like yarn wherein one unwanted component of the mixture is significantly retarded in its passage by adsorption processes as compared to the other components of the mixture. The retarded component is that which one wishes to remove from the mixture. The desired product is gathered at the outlet of the conduit. The polymeric solid separating medium is regenerated by removal of the adsorbed component in either of two ways.
