Abstract: ABSTRACT OF THE DISCLOSURE An expansible cellular void filler for dunnage uses is formed of a stack of flat, bendable strips, each except the top and bottom of which is secured at alternating longitudinally spaced positions to an overlying strip and to a subjacent strip, the secured positions being aligned in rows in a direction perpen-dicular to the planes of the flat strips, the spacing between at least two such rows being less than the spacing between other rows, so that when the strips are moved apart and bend to form cells, the cell sidewalls formed by the portions of the strips which extend between said two rows move toward a straight planar relationship prior to the sidewalls of other cells, and limit the expansion of the filler.

Abstract: ABSTRACT OF THE DISCLOSURE              A flapper valve has integral oppositely projecting hinge pins mounted in a recess provided between two abutting tubular housing members.  The flapper valve is of cylindrical segment configuration so as to maximize the opening within a conduit in which it is mounted when the flapper valve is pivoted to its open position.  The spring bias urging the flapper valve to the closed position is provided by helical springs mounted in surrounding relationship to the axis of the conduit and in an annular recess provided between two abutting tubular housing members.  The bottom surface of the actuating sleeve for the flapper is contoured so as to exert a minimum unbalanced torque on the flapper valve during opening with the mechanical opening force being balanced by an opposing force exerted by fluid pressure.  Such construction permits a substantial reduction in the size of the hinge pins and the space required to mount the pins and the helical springs thus reducing the radial proportions of the flapper valve assemblage to increase the open bore diameter.

Abstract: ABSTRACT OF THE DISCLOSURE           A novel contact electrode material for vacuum interrupters is disclosed, by which the chopping current value inherent in contact material can be reduced so that it is possible to stably interrupt small lagging current due to inductive loads without generating surge voltages.          The material is equivalent or superior to the conventional Cu-0.5Bi material in large current interrupting capability and dielectric strength.  The material consists essentially of copper, chromium, iron or molybdenum and metal carbide.          The metallographical microstructure is such that copper is infiltrated into a porous matrix formed by mutually bonding chromium  powder,  iron  or  molybdenum  powder  and  metal carbide powder in diffusion state.   In its manufacturing process, firstly copper is placed onto a powder mixture of chromium, iron or molybdenum, and metal carbide, and then the  copper and  the  powder  mixture  is  heated  within  a nonoxidizing atmosphere at a first temperature lower than the copper melting point and thereafter again at a second temperature higher than the copper melting point.

Abstract: ABSTRACT OF THE DISCLOSURE A ball-bed (pebble-bed) nuclear reactor, instead of having fuel ele-ments more or less continuously withdrawn and new or reconstituted fuel elements more or less continuously reintroduced, is initially partly filled with fuel balls of which two-thirds have a fissionable material content 12% below and the upper third 24% higher than the average content.  This filling meets the requirements of criticality in order to begin operation.  Thereafter, fuel balls are added slowly, a few hundred per day, having 150 to 250% of the average fissionable material content of the initial loading, thus preserving the criti-cality requirements, while keeping the temperature within safe limits until the reactor cavern is filled.  Thereafter, the reactor is shut down, cooled off, pressure relieved and emptied, the last step typically from above.  An ordered array of the fuel balls in regular layers avoids excess pressure loads on the reflector over the life time of the filling.  For a random packing of the balls a cross-section of the cavern that increases somewhat from the bottom upwards also avoids the excess pressure loads on the reflector.

Abstract: ABSTRACT OF THE DISCLOSURE   A snowmaker mounting structure is described useful for attaching a snowmaking apparatus used at ski resort areas to a ski lift tower.  The structure includes a generally horizontally extending boom having one end attached to an upper portion of the ski lift tower and an extending end having a snowmaker attached thereto.  Control over the region of ski slopes being covered with artificially produced snow is provided by rotatably mounting the snowmaker to the end of the boom by employing a generally vertically oriented collar through which a central tubular post is inserted and rotatable therein.  The water supply is conducted to one end of the post and a pair of turning cables are connected to the post which, through tension being applied to either one of the cables, causes the snowmaker to be rotated within the collar. This invention eliminates the necessity of providing a separate snowmaker mounting tower.
