Abstract: TITLE OF THE INVENTION                      INDUSTRIAL TECHNIQUE     ABSTRACT OF THE DISCLOSURE            A typical embodiment of the invention detects leaking fuel rods by means of a radiation detector that measures the concentra-tion of xenon-133 (Xe1 3 3 ) within each individual rod.  A collimated detector that provides signals related to the energy of incident radiation is aligned with one of the ends of a fuel rod.  A statis-tically significant sample of the gamma radiation (? rays) that characterize Xe1 3 3 is accumulated through the detector.  The data so accumulated indicates the presence of a concentration of Xe1 3 3 appropriate to a sound fuel rod, or a significantly different con-centration that reflects a leaking fuel rod.

Abstract: IMPROVEMENTS IN AND RELATING TO STEAM GENERATING PLANT                ABSTRACT OF THE DISCLOSURE            This invention relates to waste heat steam boiler plant and in particular to a transition chamber for joining a waste heat gas duct to a waste heat boiler in such plant.          The cross-section of the boiler inlet differs from that of the waste gas duct and so this transition chamber has a cross-section which progressively joins one to the other.          Instead of using refractory clad steel the chamber is made according to the invention from air-tight water cooled tube panels formed of tubes joined by fins.

Title: Method for controlling caliper and edge and corner  delamination of hardboard
Inventor: BILTON GERALD P
IPC: D21J1/00
Filed: 1976-03-04
Granted: 1981-11-10
Abstract: ABSTRACT OF THE DISCLOSURE This relates to the manufacture of wet process hardboard.  The invention involves supplying additional heat curable resin to the mid-thickness regions of the panel by injecting additional resin into the moving mat as it is being formed on a forming surface.  The region of injection of the resin is selected so that the bottom of the partially formed mat is sufficiently consolidated to resist the passage of resin therethrough while at the same time the top of the mat is still sufficiently liquid so that disturbances of the fibers of the partially dewatered mat caused by the injection of the resin have an opportunity to mend.  The resin may be injected into the longitudinal marginal portions of the mat in continuous fashion such that, after the edges of the final board product have been trimmed, the resin treated areas are exposed to view.          The additional resin reinforces the edge portions and assists in providing uniform caliper of the board across its width.  The resin may also be injected intermittently so that the resin-treated areas coincide with the corner portions of the mat after it has been cut to length thus reinforcing and assisting in providing uniform caliper as between the central portions of the board and the corner portions.  In a further variation, the resin may be injected into the moving mat along lines spaced apart to coincide with the lines of cut of saws used to produce narrow strips of panelling which are later fabricated into lap siding.  Each narrow board product ultimately produced has additional resin along its marginal edges and thus has  additional strength and resistance to moisture penetration thus making it particularly useful for lap siding and the like.

Abstract: REACTOR CORE            Abstract of the Disclosure A reactor core includes a plurality of laminations of trapezoidal shape forming the legs of the core. These legs are arranged in generally rectangular configuration with air gaps provided at the comers of the core. These air gaps extend diagonally of the core legs and are formed between the inclined faces of adjacent ends of the trapezoidal-shaped core legs. End plates each having a longitudinal section extending parallel to and fixed to one of the legs and having flanges at each end of the longitudinal section extending perpendicularly to the longitudinal section are provided for maintaining the legs of the core in assembled relation and for effecting adjustment of the air gaps. The end plates include elongated openings in the flanges thereof for permitting movement of each of the end plates, and the leg to which it is affixed, relative to the remainder of the core for varying the size of the diagonal air gaps. A plurality of metallic, non-magnetic spacers having substantially the same shape as the end plates are disposed at intervals between the end plates to separate the core laminations into groups. These spacers carry the magnetic forces tending to close the air gap. Fastening devices extend through the elongated openings and are loosened to permit movement of the end plate and its associated leg relative to adjacent legs for changing the size of the air gaps and then again tightened to hold the legs in the adjusted position. The fastening devices are accessible from the exterior of the reactor to facilitate convenient adjustment of the air gaps. Because of the separation of the laminations into groups to reduce the forces necessary to oppose magnetic forces tending to close the air gaps and also, due to the diagonal construction of the air gaps, which has the effect of reducing the flux density and therefore themagnetic force at the air gaps the fastening devices can be designed to maintain the legs in adjusted position without the need of air gaps blocking spacers in the air gaps. The air gaps, therefore, are available as passages for the flow of cooling gas for removal of heat from the reactor core.

Abstract: ABSTRACT OF THE DISCLOSURE       Conventionally, two lengths of cross T-bar engage one upon each side of the main T-bar.  In the usual con-struction, the ends of the cross bar portions just rest on the flange of the main T-bar and are therefore easily dis-placed.  In another construction, they interlock through a slot in the web, can still twist and need upper clearance to engage same with the main T-bar.  The present invention consists of each cross bar portion having a projecting nose portion upon the ends thereof with a hook or notch formed on the underside thereof.  The projecting web end engages through a slot in the web of the main T-bar and the notch or hook is engaged over an upstanding channel formed along the edge of the flange of the main T-bar so that twisting of the cross bars relative to the main T-bar is avoided and engagement can be made from below with practically zero clearance between the ceiling and the main T-bar.  Further projections from the ends of the flanges of the cross T-bar may engage notches in the flanges of the main T-bar and firmly lock the cross bars into position to prevent movement up or down or from side to side as well as preventing twisting from occurring.
