Abstract: IMPROVEMENT IN FLUIDIZED RED APPARATUS    ABSTRACT OF THE DISCLOSURE             Apparatus for carrying out fluidized operations comprising an elongate generally upstanding housing, said housing defining and upper chamber, an intermediate chamber and a lower chamber.  A plurality of open ended tubes is positioned inside the intermediate chamber.  The open ends of each of said tubes communicates the interior of said tubes with the upper and lower chambers.  An improved spacing means is provided in the upper chamber, said spacing means having a plurality of tapered openings wherein said openings are coterminous on the upper surface of said spacing means and spaced on the lower surface of said spacing means.  The openings on the lower surface are in concentric communication with the open ends of said tubes in the upper chamber, thereby communi-cating the interior of said tubes with the upper chamber.  The improved spacing means prevents the formation or "dead zones" where solids may lay for extended periods and be subjected to high temperatures and danger of explosion.

Abstract: HIGH-VOLTAGE FUSE LINK AND METHOD OF MANUFACTURING SAME ABSTRACT OF THE DISCLOSURE A fuse link and a method of manufacturing same are disclosed. The fuse link comprises a fusible element extending between an upper terminal and a lower terminal. The lower terminal includes a compressed segment of a multi-strand cable to which the fusible element is attached. In practicing the method of the present invention, a segment of the multi-strand cable is first radially compressed, as by cold-forming, to pro-duce a longitudinal receiving region or pocket indentation for receiving an end of the fusible element. Thereafter, an end of the fusible element is placed into the receiving region. The region is then further com-pressed and collapsed to secure the fusible element therein by crimping a compressible sleeve previously placed around the fusible element and the cable-segment.

Abstract: ABSTRACT       Neutron activation is used to analyse the silicon and aluminium content of samples of material, such as bauxite ore and coal.  The analysis can be performed on bulk samples, on material on a moving conveyor belt, or on the walls of a borehole.  The method involves high energy neutron irradiation of the sample, measurement of the thermal neutron flux in the sample, and monitoring the gamma radiation from the sample at energies of (a) 1.78 MeV and (b) 0.844 MeV and/or 1.015 MeV.  Such gamma radiation is produced on decay of (a) 28Al and (b) 27Mg isotopes, produced by the reactions 28Si(n,p)28Al and 27Al(n,p)27Mg.  A single gamma ray detector is used.  The analysis preferably utilises equations which include terms to compensate for (a) the production of radiation at 1.78 MeV as a result of the production of the isotope 28Al from 27Al by the thermal neutron reaction 27Al(n,y)28Al, and (b) the Compton scattering of 1.78 MeV gamma radiation and background.                             -oOo-

Abstract: ABSTRACT OF THE DISCLOSURE          An improved prestressed concrete tank having a core wall comprising elongated panels of precast concrete assembled in spaced, side-by-side relationship.  The panels having on their outer faces a sheet of metal presenting parallel longitudinal undercut channels and a lateral flange extending parallel with the elongated sides of the panels and laterally outwardly therefrom.  The sheet metal flange has a lip on the outermost edge which extends from the tank in a direction substantially perpendicular to the panel.  The flange lips of adjacent panels are spaced from one another.         A sheet metal, channel shaped splice member is interposed in the space between the flange lips of adjacent panels, the splice member having upstanding sides which abut the flange lips of adjacent panels and the flange lip and the abutting upstanding side being seamed together in a tight fold, thereby locking adjacent precast concrete panels together with a watertight seam.  Each of the panels may have on the outer face thereof a plurality of sheets of metal with parallel longitudinal undercut channels wherein the lips of adjacent sheets on the same panel about one another and are folded together in a continuous metal-to-metal seamed joint which is set within the concrete.

Abstract: ABSTRACT       A sharpening device, for the saw chain of a motor chain saw, with a holding device for a sharpening element which is arranged in the region of the reversing radius and is curved approximately concavely with respect to the center of this reversing radius. The sharpening element is seated upon an adjustment lever which is pivotable in a direction toward the saw chain.  This lever cooperates with a screw device which determines the feed path of the sharpening element.  An actuating handle is provided for the feeding of the. sharpening element; this handle is arranged on that side of the housing of the chain saw located remote from the free reversing end of the guide bar of the saw chain. The actuating handle is preferably release-ably secured in the grasping range of the front handle of the chain saw.  The actuating handle is connected by a yieldable shaft with a threaded bolt associated with the feeding device, and the nut piece of the threaded bolt is seated in an extension of a support plate connected with the guide bar, that end segment of the threaded bolt which projects freely from the nut piece pressing against an adjustment lever pivotally journalled on the support plate.  The adjustment lever supports the sharpening element and is spring biased, with the spring endeavoring to pivot the adjustment lever, together with the sharpening element, in a radial direction against the axis of the reversing chain gear.

Abstract: Title: "Foam Extrusion Apparatus and Method" ABSTRACT OF THE DISCLOSURE An extrusion system for the production of foam boards, billets and the like products includes an ex-truder (20) at a first higher elevation (22) extruding foamable resin through a die in the upper end of an elongated vacuum chamber in the form of an inclined barometric leg (26) which extends at its lower end into a shallow but large surface area pool (39) of liquid such as water. An elongated shroud or hood (44) on the lower end of the leg reduces the pressure head of water above the foam product as it exits the leg and moves out of the pool for processing at a lower second elevation. The large area of the pool reduces its depth for a given volume and minimizes fluctuations in the level of the pool and the pressure head above the product when the vacuum changes. In one embodiment the pool extends beneath substantially the entire floor of the building (30) enclosing the second lower elevation (31) in which the subsequent processing occurs. In another embodiment the pool (165) extends beneath the leg with the pool also serving as structural footings for the support of the leg and the platform forming the first higher elevation.
