Abstract: An improved structure for rotational support for a heat-dissipation fan is disclosed, comprising a hollow ceramic bearing passing through and concentric with the fan rotor and rotating with said rotor, a hollow ceramic support bearing fixedly mounted to the base of the fan, and a hollow or solid ceramic axle tube passing through the inside of said bearing and rotating freely to reduce friction and allow high-speed rotation. The exterior surface of said bearing is ground or otherwise formed to provide better connection with the rotor, while the interior of the bearing and exterior of the axle tube are further processed to reduce contact area therebetween to reduce rotation friction. This improved structure has achieved reduced friction, reduced noise, reduced power consumption, longer life and higher rotational speed.

Abstract: A cardboard holder for business cards, suitable for use on a bulletin board or a hard surface, is disclosed. The holder is made from a single piece of cardboard, folded to form a box of appropriate size to hold a number of business cards, displaying the cards so a prospective customer or client can take one. The device described is made from a pattern, cut and folded to form the card holder. Different embodiments of the invention allow the holder to be tacked onto a bulletin board using thumbtacks, affixed to a hard surface using an adhesive tape, or glued together and onto a surface with glue that is administered to the cardboard pattern during manufacturing. Additionally, the holder can be imprinted with the information contained on the cards it holds, to simulate the look of the cards.

Abstract: A method is disclosed whereby existing on future motion picture films are modified for exhibition at frame rates significantly higher than those used for general theatrical release. Films photographed at customary frame rates (such as 24 frames per second) are printed, with each frame printed twice, onto film for exhibition. The resulting film is shown at double the original frame rate (48 frames per second, for example). The method disclosed here allows more light to pass through the film than is possible with conventional projection methods. The method disclosed here is also compatible with any standard or nonstandard film size or aspect ratio. This method also allows light brightness to be varied for certain scenes or sequences, thereby allowing the viewers to perceive different amounts of visual impact for different scenes or sequences, a feature not available through conventional motion picture exhibition methods.

Abstract: A method is disclosed whereby cinematic image components photographed at one frame rate are composited with other cinematic image components photographed at a higher frame rate, to produce images containing some components that deliver a more realistic impression to the audiences viewing such images than are delivered by the other image components. This method is applicable to any combination of frame rates, as long as one frame rate is greater than thirty frames per second, and the other is thirty frames per second or less. Scenes or sequences photographed at different frame rates and containing entire images can also be combined into a single motion picture by intercutting in accordance with this method. In addition, this method allows conversion of films photographed at nonstandard frame rates to be converted to a universal format for exhibition in conventional motion picture theaters, thus eliminating the restriction of films of this sort to special venues.

Abstract: A method is disclosed whereby film images designed to produce a high-impact effect upon the members of an audience viewing a motion picture film are composited with other images designed to provide the conventional cinematic effect upon such audience members. "High-impact" film images photographed at forty-eight frames per second are composited with "conventional" images photographed at the traditional motion picture rate of twenty-four frames per second, with such images superimposed onto the same film frame. Certain portions of the motion picture image seen by the audience deliver a greater illusion of reality than other portions of the same motion picture image. In addition, the method described can accommodate the intercutting of discrete scenes presenting either high-impact or conventional cinema experience. The method disclosed here also allows easy conversion of films to the conventional twenty-four frames per second rate associated with conventional motion picture release and distribution.

Abstract: The device described here allows for the raising or lowering of the mask which sits along the bottom edge of the screen in a motion picture theater and, along with the top and two side masks, frames the entire screen. The lower mask is supported by a number of support units, each containing two arms, equal in length and pivotally joined at their apex, where they are also attached to the bar that supports the screen mask. The arms are moved further apart or closer together at their lower ends, so that they push the bar supporting the screen mask up or down. A rotating shaft, with sections of oppositely-pitched threads, is connected to a motor. Sleeves with complimentary inside threads are pivotally mounted to the support arms, such that rotation of the motor in one direction moves the loser ends of the arms further apart and rotation in the other direction brings the lower ends of the arms closer together. Thus, the screen mask can be raised or lowered by motor rotation in one direction or the other.

Abstract: A method is disclosed whereby a motion picture projector is equipped to operate at two or more different speeds, such as 24 and 30 frames per second. It is envisioned that different parts of a motion picture may be recorded at different frame rates, to variably impart a highly intense effect upon the audience, expanding the parameters of creative control for the producer of the film. In operation, the method described facilitates switching between these different frame rates, both during the presentation of a single motion picture and between pictures. Cue signals recorded onto the film actuate the change in speed. The projector is automatically set to switch operation into a different speed, and the frames of the film that will be shown during the transitional period are prepared to give the audience the impression of a smooth transition between speeds.

Abstract: A method is disclosed for quickly and efficiently calibrating the color filtration levels of a photographic enlarger for the characteristics of the printing paper on which prints are to be made, and subsequently adjusting the enlarger for optimize adjustment of the color values for final printing. A test print is made of a standard transparency in the conventional manner. A charge coupled device (CCD) TV camera is then substituted for the printing paper. The output of this camera is connected to a video monitor and to an oscilloscope set to show the amplitude of its output over time. The input of this camera is adjusted to match the color values of the first test print, and the enlarger is adjusted so that the colors in the image showing on the video monitor screen are correct. The transparency to be printed is then substituted for the standard transparency and the enlarger adjusted for correct color filtration levels for the transparency to be printed.
