Abstract: ABSTRACT   A unit for a shrinkage joint assembly for installation in construction slabs particularly poured in place concrete and prefabricated concrete slabs for use as floors, walls, ceilings, tunnels, etc. and where the shrinkage joint assembly is mounted at the working surface of and between pairs of such slabs. The assembly comprises of pair of the units one adjacent each slab with an elastomeric bead bridging and coupling the units together.  The units are longitudinally extending and each has a first longitudinally extending recess for receiving the bead, a second longitudinally extending recess with ribbed walls for receiving screw threaded members for vertical adjustment of the unit, and a third longitudinally extending recess for anchoring means to be imbedded in the adjacent slab.  A marking groove is formed on the surface of the unit so that holes can be drilled into the second recess for receiving screw threaded members from above for vertical adjustment and prestressing of the unit.

Abstract: ABSTRACT OF THE DISCLOSURE           A novel rotary blade for pruning machines is provided herein.          The rotary disc-type blade comprises a disc portion and a cutting blade portion.  The cutting blade portion includes a plurality of cutting blades projecting radially from the periphery of the disc portion.  The disc por-tion and the cutting blade portion are each made of a particularly recited flexible, high molecular weight, elastomeric material.  A mounting hole is disposed in the center of the disc portion and a rigid core member is embedded in the elastomer surrounding the mounting hole.  The diameter of the core member is 1/3 to 1/2 that of the diameter of the rotary blade. A plurality of buffering holes is disposed along the periphery of the disc portion along the radii connecting the center of the disc portion with the body of each cutting blade portion.  The rotary blade has good tensile strength, good tear resistance, good abrasion resistance, good light stubby lity and good flexibility and will give far less shock to the operator when compared with known bar-type blades, when the blades collide with a rigid obstacle.  This shock is also substantially reduced by providing a plurality of holes along the periphery of the disc portion or supporting member of the blade.  Because of the extraordinary high speed of rotation, up to 6,000 rpm, even if the first blade which contacts a rigid stalk of weed is bent, the next blade instantly contacts the stalk damaged by the first blade body and, consequently, smoothly cuts down the stalk with little shock being transferred to the operator.

Abstract: U.S. 14,107 ABSTRACT OF THE DISCLOSURE     This invention relates to a process for the separation of isotopes of an element, preferably uranium, utilizing certain uranyl compounds having the formula (U02AA')n  wherein A and A' are monovalent anions and n is a number from 2 to 40  With reference to the drawing, which schematically represents an apparatus in which the process may be conducted, the uranyl compound is vaporized in a heated oven (1) to produce a molecular beam (8) which is irradiated by a CW CO2 laser beam (5).  Molecules containing one of the isotopes absorb radiation from the laser beam (5) preferentially over molecules of the other isotope and undergo unimolecular dissociation.  The dissociation fragments to which sufficient random translational energy is imparted leave the molecular beam (8) and are collected by cooled cylindrical collector (11).

Abstract: IMPROVED DRUM BRAKE ADJUSTER                         ABSTRACT OF THE DISCLOSURE The present invention relates to an improved drum brake assembly having an automatic adjuster to compensate for lining wear to a pair of brake shoes.  A backing plate includes an anchor to pivotally support the pair of brake shoes and to secure a hydraulic actuator thereto.  An extendible member cooperates with the pair of brake shoes to define a non-braking position and the hydraulic actuator is operable to move the pair of brake shoes to a braking position in engagement with a rotatable member.  A pawl is pivotally engageable with the extendible member and the hydraulic actuator via a spring extending from one of the pair of brake shoes to the pawl so as to pivot when the hydraulic actuator is operable.  The pivot-ing of the pawl causes the pawl to extend the extendible member if the move-ment of the pair of brake shoes is above a predetermined value.  The pawl includes an arm which is pivotally engageable with a piston of the hydraulic actuator.  The arm also defines an arcuate abutment between the other brake shoe and the hydraulic actuator.  In addition a parking lever may also be pivotally engageable with the hydraulic actuator and define another arcuate abutment opposing the one brake shoe.

Abstract: ABSTRACT      An anode composition as the sole source of aluminum comprising an aluminous material such as aluminum oxide and a reducing agent such as carbon for use in the electro-deposition of aluminum at low temperatures.      The electrodeposition of aluminum at low temperatures and low electrical potential by the electrolysis in a fused salt containing a composite anode within the electrolytic cell by the reaction of the anode under electrolysis to produce aluminum during the electrolysis.  An aluminum compound ionized at the anode is electrolytically reduced to molten aluminum at the cathode and an anion formed at the anode reacts to produce CO2 gas at the anode.  In one operational mode a unique porous membrane passes electrolyte or other dissolved material while withholding undissolved impurities.      Aluminum also may be electrodeposited from aluminum oxide to produce molten metal,  at a temperature as low as the melting point of the metal and with the use of an all fluoride containing bath and the composite anode.      Dimensionally stable cells for the electrodeposition of aluminum may have sloped walls forming electrodes that permit the maintenance of a reduced anode current density as well as anode-cathode spacing when using the low temperature non-aggressive baths permissible with the particular composite anode composition.
