Abstract: A boring bar apparatus for removing material from the interior of a rigid structure through an elongated cylindrical opening therein. A bar mounted for rotation within the cylindrical opening carries a cutting head whose position relative to the opening can be independently varied radially and axially as the bar rotates. In this way, precision cuts can be made on otherwise inaccessible areas of the structure.

Abstract: Polycarbonate membranes useful for hemodialysis are fabricated from polyether-polycarbonate block copolymers by a water gelation process. The process comprises casting onto a substrate surface a layer of a multicomponent casting solution comprising the copolymer dissolved in a water-miscible organic solvent together with a cosolvent which acts as a swelling agent for the copolymer, drying the layer to partially evaporate the solvents therefrom, immersing the partially dried layer in water to form a gelled membrane, and stripping the gelled membrane from the substrate surface. The membrane has improved strength and improved permeability to solutes in the "middle molecule" range while maintaing clinically acceptable ultrafiltration rates and clearance of low molecular weight solutes.

Abstract: A cartridge is provided in which a tubular element extends axially of the cartridge from the primer through the powder charge in the cartridge. The tubular element can be made of a combustible material such as paper or plastic, or an explosive material or one which fragments readily.

Abstract: An automatic seed planter which includes an elongate, upwardly-opening V-shaped trough with front and rear ends defining a longitudinally extending, upwardly opening seed-conducting channel, a seed receiving chamber at the front end of the trough, elongate guide means in the chamber overlying the channel to pass seed from the chamber downwardly and longitudinally rearwardly into the rear end portion of the channel, means to vibrate the trough and cause seed in the chamber to migrate past the guide and into the channel at a predetermined rate, and a seed discharge opening at the rear end of the channel.

Abstract: Apparatus and methods are provided for reducing solid combustible particles by heat and abrasion to a condition in which they can be burned completely and without the production of objectionable solid particulates in the exhaust gases. Solid combustible particles are carried into an outer chamber of the device by a low pressure transport air stream, with additional air at high pressure and high velocity being introduced into the same chamber in a relation driving the solid particles rapidly and circularly within the outer chamber and about an inner chamber of the device. Impingement of the particles against one another and/or the walls of the outer chamber during such swirling motion, supplemented by partial oxidation of the combustibles, raises the temperature of the particles and comminutes or reduces their sizes to form a very highly combustible flowable aerosol mass which will burst into flame when contacted by a stream of secondary combustion air.

Abstract: A novel method for stimulating the flow of oil from the pay zone of a formation traversed by a bore hole which involves the conversion of liquid water into steam in situ in heat transfer proximity to the pay zone. A novel oil tool adapted to be lowered and suspended within the bore hole in proximity to the pay zone having a closed casing or shell within which is contained means for the in situ generation of steam, with the casing being provided with valve means whereby the steam thus generated can pass through the shell and into contact with the pay zone. A novel electrical control system for the operation, regulation and malfunction-detection of the oil tool from the ground surface.

Abstract: A carrier for releasably engaging and supporting a pair of skis and a pair of ski poles in horizontal hand-carrying spaced relationship with the poles above the skis, whereby the poles function as a carrying handle. The carrier comprises a pair of flexible coupling straps, each of which includes a lower adjustable ski-engaging loop, on upper adjustable ski-pole-engaging loop, and a vertical intermediate hand-clearing web therebetween.

Abstract: A flexible sheet or garment to be worn on or around the human body, or body member for cooling and having two flexible plastic sheets or films which are joined or adhered to form two tortuous, adjacent, generally co-extensive, non-communicating fluid paths, one of said fluid paths being substantially and permanently filled with a viscous liquid heat transfer media and the other of said fluid paths being in communication with a reservoir of pressurized gas, means between said reservoir and other fluid path for regulating the flow of pressurized gas through said other fluid path and a pressure relief means in said other fluid path and positioned at a point remote from said reservoir to limit the gas pressure and gas flow rate in said other fluid path; and means for holding said sheet or garment in place on or around the human body, or body member.

Abstract: A belt assembly capable of functioning as both a safety belt and a support for a tool carrier, and which includes a first belt adapted to extend about the back of a user's waist and carrying two connecting rings at opposite sides of the user's body, and a second belt which also extends across the back of the user's waist and is attached to the first belt at a predetermined location but not at a second location at which the belts are separable to allow a tool carrier to be slipped onto and be suspended by that portion of the second belt. The first belt is preferably shaped to have two portions one of which is received behind and supports the user's waist, and the other of which can extend downwardly between the rings to support the user's body in a sitting position.

Abstract: A high-strength, light-weight, fired clay body which is characterized by relatively greater surface oxidation than interior oxidation with accompanying surface layer shrinkage. The clay body is quick-dried and quick-fired to substantially uniformly oxidize the surface layer to maturity while maintaining the interior of the body in a relatively unoxidized and unfired condition.

Abstract: An elongated tube (preferably stainless steel) is maintained at a temperature of at least about 1000.degree. F. throughout its length. Coal or other carbonaceous feed material is moved through the tube at a uniform rate of speed in the substantial absence of air, with the feed material being constantly churned or turned as by a screw conveyor. The churning of the feed material and the diameter of the tube is such that the material is subjected to "shock" heating, whereby gases and vapors are violently released from the solid mass and are removed therefrom at a vacuum of from about two to about five inches of mercury, with said gases and vapors passing through the aforesaid churning mass. The residue is recovered and the gases and vapors are subsequently passed through conventional condensers and scrubbers to liquify the oil and separate the gases and the water.
