Abstract: Inventor   :   Walter L. Carter Title      :   TOOL HOLDER                   ABSTRACT OF THE DISCLOSURE         A tool holder adapted to be swivelly mounted on a lathe turret includes an open channel to horizontally support an elongated cutting tool projecting outwardly to operate on a rotating workpiece.  Dowels are insertable in aligned holes vertically defined at predetermined locations through the tool holder.  The placement of two pins in a desired alignment relative to a line of reference permits the adjustment of the tool holder upon the face of the turret to locate the tool horizontally at a selected angle with the workpiece.  Snap rings are close fitted to the dowels so as to frictionally engage the dowel along its length, fixing the position of the dowels in the vertical holes.  In a particular embodiment the lower surface of the tool channel is coplanar with the mounting surface of the tool holder.  A shim can be inserted to raise the lower channel surface to accommodate the centerline requirements of lathes designed for larger diameter tools.

Abstract: APPARATUS FOR WELDING AN END PLUG       IN A NUCLEAR FUEL TUBE                   ABSTRACT OF THE DISCLOSURE         Apparatus for precisely positioning the seam on an end of a nuclear reactor fuel rod opposite from a welding electrode in a weld chamber.  The circumferential seam is formed by abutting surfaces at the end plug-fuel tube inter-face, and it is important that the seam be located in an exact position relative to the welding electrode tip.  This is accomplished by providing a stop member against which the fuel plug rests during the time an end plug is welded.  The distances are chosen such that when the end plug is fully seated in the stop member, the electrode tip and seam will be located in optimum positions to effect the making of high quality welds.  Open communication is established between the inside of the fuel rod and vacuum equipment which is used for evacuating the fuel rod of air or other gases during the welding operation through an axial passageway in the stop member.  When evacuation is complete and the pressure drops to a predetermined low value, a vacuum switch respond-ing to fuel rod pressure acts to close an electrical circuit which energizes the welding electrode.  If the end plug is not properly seated in the stop member, the desired vacuum cannot be drawn, the vacuum switch will not close, thus precluding initiation of the welding process.

Abstract: SEISMIC SOURCE FOR USE UNDER WATER          ABSTRACT OF DISCLOSURE:  A seismic source is described which drives one or more jets of high velocity water into an underwater environment and then abruptly terminates the jets.  The momentum of the free jet columns generate vapor cavities in the water away from the housing of the source which cavities collapse coherently to generate the seismic signal.  A piston and a valve sleeve are slidably mounted in a cylinder in the housing.       The piston seals off a volume of gas on its rearward side.          The forward side of the piston defines one surface of a chamber.          The chamber receives high pressure water from an inlet.  In its rearward position, the valve sleeve seals a set of jet apertures in the side of the cylinder.  In its forward position the valve sleeve opens the apertures, exposing the chamber interior to the exterior underwater environment.  With the valve sleeve in its rearward position with the apertures sealed, the high pressure water entering the chamber moves the piston to its rearward position and compresses the gas.  The sleeve is hydraulically actuated upon command to abruptly open the jet apertures, enabling the piston to move forwardly under the pressure of the compressed gas, driving the water through the jet apertures so as to form the jets.  The piston enters the interior of the sleeve near the forward end of its stroke and, concurrently, abruptly terminates the jets.  To re-arm the source, the sleeve is actuated to close the jet openings whereupon the high pressure water re-sets the piston.  Upon the next command, the valve sleeve is again actuated to open the apertures and the next seismic signal is generated.

Abstract: COMBINATION APPARATUS AND METHOD FOR CHROMATOGRAPHIC SEPARATION AND QUANTITATIVE ANALYSIS OF MULTIPLE IONIC SPECIES                 Abstract of the Disclosure Apparatus and method for chromatographic separation and quantitation of different ions of like charges in a sample, e.g., cations or anions.  Referring to anion separation, the sample is directed to a first chromatographic column of the ion exclusion type in which the weak acids (e.g., carboxylic acids) and their salts are resolved and separated from a fraction of strong acids (e.g., mineral acids) due to Donnan exclusion.  The resolved weak acids are passed to a conductivity cell for quantitative detection.  The strong acids are directed to anion exchange bed with a highly ionized developing reagent and eluted in resolved form.  The effluent is passed to a suppressor ion exchange bed wherein the developing reagent is converted to a weakly ionized form without destroying the anion separation.  Then, a fraction of the strong acids is detected with the same or a different conductivity cell.  Prior to separation, the strong acids are preferably directed through a concentrator column formed of ion exchange resin in which they are retained but not resolved while the remaining solution is removed. Thereafter, the developing agent used for separation of the strong anion is passed through the concentrator column to remove the anions for resolution.  The same technique can be employed for cations.

Abstract: ABSTRACT OF THE DISCLOSURE          A hybrid integrated circuit for high output power having a conductive pattern on a ceramic substrate, a lead frame connected to said pattern, and electronic components mounted on said pattern wired with one another, has been found.          When said conductive pattern has an inductor in a spiral shape, the same spiral pattern is conformed on the lead frame, and those two spiral patterns are overlapped.  Thus, the resistance of the inductor is reduced since the conductive pattern and the lead frame pattern are connected parallel to each other.  Then, a large current can be loaded to said inductance with only a small loss.  As the material of the lead frame is cheap, the resultant hybrid integrated circuit can be manufactured at a lower cost.
