Abstract: Process for creating a shaped product from a plurality of particles by having a heat beam directed thereon in a desired pattern, fusing the particles into a structure in the desired pattern where the heat beam was directed, such shaped product being removed from the remainder of the unfused particles, such process in some embodiments being a continuous process.

Abstract: A system for teaching artistic methods and techniques by providing both images on a television screen and instructional data and providing means for copying the image on a sheet of clear or translucent material place on a portion of the television screen.

Abstract: A process for making a silicon carbide foam structural material utilizing continuous and non-continuous processes where bead members are mixed with silicon powder-carbon powder and molded into a shape. The bead members are then removed by melting. The remaining silicon powder-carbon powder structure, having been formed with a plurality of apertures therein from where the beads have been removed, is further heated to a point sufficient to form a silicon carbide structure retaining such plurality of apertures to create a silicon carbide foam.

Abstract: A structural beam having a core with a multiplicity of wrappings therearound of shrinkable material, such wrappings being of greater mass than the core and in one embodiment having interlayers of fiber materials between the wrappings of shrinkable material.

Abstract: A game having circuitry for the conversion of a player's brain wave intensity to direct the movement of a rotating circular visual display. The game in one embodiment can be played by two players competing with one another and the visual display can include a variety of changing patterns.

Abstract: A game having a magnetically permeable game board areas, each of the areas having a magnet positioned thereunder below the game board and a plurality of magnetic game pieces to be propelled by a player by a repeller toward the game board in an effort to position the magnetic game piece on an area having the highest scoring value associated therewith.

Abstract: A method of operating a pulse thruster comprising delivering electrically charged fuel attracted to a plate having an opposite charge where such fuel is ignited, causing an impulse force, and repeating the process.

Abstract: A pulse thruster delivering electrically charged fuel attracted to a plate having an opposite charge where such fuel is ignited, causing an impulse force which process is repeated.

Abstract: A structural material comprising a plurality of irregularly arranged members contacting one another with the points of contact forming junctions, the members being coated, which coating holds the members together to form a strong integral structural material and methods for producing same.

Abstract: A book having self-illuminating pages, each page utilizing transparent sheets sandwiched around an opaque sheet with indicia imprinted on the transparent sheets illuminated by a light source within the spine of the book passing light in through the edges of the transparent sheets facing the spine, such light passing through the planar body of the transparent sheets, illuminating the indicia imprinted thereon.

Abstract: A closed-system hot gas device for flotation in the atmosphere having a rigid cap and flexible sides with an interior gas-heating element.

Abstract: A mill roll having a pair of ceramic, hollow rollers with the chambers defined in each filled with a plurality of particles with spaces defined therebetween including means to enter fuel therein to be burned to heat the rollers to incandescent temperatures.

Abstract: A device and method for determining the melting point of a material having light reflective properties by determining changes in the reflective properties of the material while under pressure as it is being heated.

Abstract: A method of creating hollow spheres and spheres produced according to such method, such method including suspending in a zero gravity environment a molten resin material mixed with a blowing agent which is caused to foam expanding into a spherical mass wherein the insides are hollowed out and the exterior sphere wall is solidified and the further process of creating adjoining spheres.

Abstract: A three-dimensional imaging system having a viewing chamber in one embodiment with electrode vibration plates disposed above and below the viewing chamber with a plurality of minute particles having a changeable charge moving rapidly back and forth between the vibration plates and in another embodiment having a moving screen in the viewing chamber with illumination of selected of the particles or screen provided at a desired height in the viewing chamber at a plurality of positions within the viewing chamber to produce a three-dimensional image based upon an image-sensing device's output directed to control the points of illumination within the viewing chamber.

Abstract: A fire-resistant foam having hydrogen-filled cells for use in airship/balloon envelopes.

Abstract: A therapeutic vibratory bath with a containment chamber for receipt of fluid medium and the individual to be bathed, such chamber having in one embodiment a plurality of vibration-producing devices arrayed around the chamber, such arrays disposed at a plurality of levels, the operation of which vibrators is performed in a sequence to produce a desired vibrational pattern in the medium around the individual being bathed.

Abstract: A structure to replace the outer wall of a pipe elbow to provide wear resistance in pneumatic conveying pipes carrying particulate material, said structure having a chamber with a source of vacuum suction therein disposed on the outer portion of the elbow with a screen disposed in the chamber where particles passing through the pipe are drawn and held by the suction against the screen member to form a particle accumulation area which is struck and worn by the oncoming stream of particles. Worn areas of the particle accumulation are replaced by new particles passing through the pipe.

Abstract: A musicians telephone interface that interconnects an instant location through a telephone line to a remote location such device having inputs to receive the sound from musical instruments and/or vocalization at each location with balancing circuitry and broadcast means at each location for the musicians at each location to hear the music of one another simultaneously balanced for collaboration and production of music.

Abstract: An electrostatic display device having a plurality of particles moving back and forth in a chamber illuminated by light. The chamber has oppositely charged top and bottom plates whereby the particles are alternately electrostatically attracted to and repelled from the plates while illuminated by the light, thus creating a constantly moving decorative light display.
