Abstract: ABSTRACT       A furnace for burning dry or wet wood waste products such as hogged bark and the like is pro-vided with a grating therein comprised of aligned rows of bricks resting on supporting cross beams, with at least some of the rows of bricks maintained a uniform distance from other rows of bricks by spacers disposed between such spaced-apart rows of bricks.  The furnace is charged by turbulent air entering both above and below the grating, with a select portion of such air being pre-heated.  A temperature gradient is established between an area immediately beneath the grating and the area above the grating in the range of 2200°F and can be con-trolled by selected initial placement of the bricks and spacers to achieve an optimum cross sectional area for flow of heated, turbulent air through the grating to produce a temperature for efficient heating, drying and burning of wood waste products in an essentially pollution-free manner.

Abstract: ABSTRACT               A simple and inexpensive device for measuring radial expansion of tube-like structures which is particularly useful to measure male potency.  A radially expansible loop made of a flexible, relatively slippery thermoplastic tube havlng an elongated tail extending therefrom is drawn tight around the flaccid penis, by means of draw means at the end of the tail, and held in place by an adhesive patch.          Should an erection occur the tail slides partially out of the thermoplastic tube to accommodate the radial expansion which occurs and remains in the extended position until manually retracted by pulling the draw means at the end of the tail.          The radial expansion can he assessed by measuring the exten-sion of the tail exposed.

Abstract: Abstract of the Disclosure The magnitude of a DC high voltage supplied to an internal element of a CRT is varied by a thermionic valve that is located within the envelope of the CRT and that forms a voltage divider with an external load resistor. Only a small scale signal referenced near ground is needed to produce a several thousand volt change in the high voltage supplied to the internal CRT element. The variable high voltage may control a variable deflection factor, variable spot size, or in the case of a beam penetration CRT, either variable persist-ence or variable trace color.  In a particular beam penetration color CRT having a split anode the thermionic valve comprises a tetrode flood gun coupled by an electron mirror to a plate region in the neck of the CRT.

Abstract: HIGH PRESSURE BALL VALVE     (Abstract of the Disclosure) A ball valve designed for high pressure shut-off at fluid pressures approaching the ultimate compressive stress of plastic annular seat rings which are employed.  The ball member is trunnion mounted in order to carry the total force of the shut-off pressure and the seat rings are disposed in seat ring carriers.  Each seat ring includes a spherical ball engaging surface having a radius slightly smaller than the radius of the ball.  Each carrier is continuously urged toward the ball by a plurality of disc springs in order that the seat ring engaging surfaces will be in continuous sealing engagement with the ball surface.  The seat ring engaging surfaces are configured so that at least the areas thereof located adjacent the outer diameters will be first to sealingly engage the ball.  The valve components are configured and dimensioned to limit the effective area on which fluid pressure may act in urging the seat rings into ball contact for thus controlling compressive stresses which may be exerted on the plastic seat ring material.  Also, fluid pressure urges the seat rings toward the ball to enhance sealing engagement with the ball regardless of the position of each seat ring upstream or downstream of the ball from the source of fluid pressure and also with the valve in the open position. The inventive concept involved may advantageously be employed in a variety of valve bodies to accommodate a plurality of fluid shut-off applications.

Abstract: ABSTRACT OF THE DISCLOSURE     A film stirring system for developing photographic film.  The system includes a container for the developing solution and photographic film.  An agitator within the container has a central hollow shaft and upper and lower perforated disks for supporting a roll of photographic film.  A first magnetic disk is encapulated in plastic, to prevent contamination of the developing solution.  This magnetic disk is secured to the hollow shaft and drive means is provided for imparting oscilating motion to the magnetic disk on the shaft.  The drive means includes a housing, a motor, a circular crank on the motor, and a connecting rod secured between the periphery of the circular crank and a rack slider disposed in a groove in the housing for gear slideable movement.  A pinion is mounted for rotation on the housing and meshes with the rack slider.  The pinion gear is connected to a shaft which has a second magnet means thereon to connect with the first magnetic means on the hollow shaft in the container.  It is thereby possible to impart oscilating movement to the photographic film carried by the hollow shaft while providing a light proof detachable container capable of lightproof liquid-proof interconnection with the drive means.  The magnetic disk on the hollow shaft is encapsulated in plastic to prevent contamination of the developing solution by the barium iron oxide material which could result in irregularities in the development of the film.  The oscilating movement imparted by the crank type drive means is perferable to rotary motion.
