Abstract:
A decorated ceramic floor tile is disclosed, comprising a clay tile substrate, an initial glaze layer applied to the tile substrate, and a high-fired glazed decal image applied to the tile such that the decal extends substantially at least to the edges of the initial glaze layer around the entire perimeter of the tile substrate. A ceramic floor having a substantially continuous decorative image thereon, comprising a plurality of ceramic floor tiles of the invention also is disclosed. A process for making floor tiles of the invention includes providing a clay tile substrate, bisquing the clay substrate to remove moisture from the clay, applying an initial glaze layer to the bisqued clay tile substrate, performing a first firing of the glazed tile substrate, applying a glazed decal image to the fired glazed tile such that the decal extends substantially at least to the edges of the initial glaze layer, and performing a second firing of the decaled tile such that the decal image is substantially fully bled to the periphery of the tile around the entire perimeter of the tile.
Abstract:
The tuning control system of a double-conversion tuner includes a phase locked loop type of frequency synthesizer for controlling the frequency of a controllable oscillator comprising the first local oscillator of the double-conversion tuner according to the frequency deviation of the difference between the frequencies of the first and second local oscillators from a reference frequency in order to compensate for the drift of either one of the local oscillators. An up/down counter which counts in one sense in response to the first local oscillator signal and in the other sense in response to the other local oscillator signal is used to generate the frequency difference signal. Because the frequency of the first local oscillator is always greater from the frequency of the second local oscillator the up/down counter can be implemented in the form of a simple pulse swallower.
Abstract:
A composite video signal including a timing component and a caption video signal having no timing component are combined to form a resultant video signal for application to a television receiver. The caption signal is produced by a character generator that is normally synchronized with the timing component of the composite video signal. A substitute timing signal is supplied to the character generator and also added to the player output signal under conditions which interrupt the timing component of the composite video signal whereby captions may be continuously displayed on the television receiver notwithstanding partial or total interruption of the composite video signal.
Abstract:
A video disc player, for use with a television receiving device having a tuner, includes a power switch, a source of baseband video signal and a switchable multi-channel TV modulator. Upon closure of the power switch the baseband signal is modulated on a selected TV channel and supplied to the television tuner. Channel prompting apparatus in the video disc player responds to initial closure of the power switch and to the selected channel of the modulator to produce a message perceptable to a user of the player, the message being indicative of the selected TV channel of the modulator, for prompting the user to select the corresponding channel on the receiving device. The message is communicated to the user by sight or sound upon initial activation of the player and may be subsequently followed by a further message indicative of an operating parameter of the player such as a playing time indication of the disc being played.
Abstract:
A memory type tuning system having memory locations for storing information corresponding to a limited number of preferred tuning positions includes apparatus for examining the contents of each of the memory locations when information corresponding to a tuning position is being entered to determine if duplication information corresponding to the same tuning position has already been entered in one of the memory locations. If so, the new information is entered in the memory location containing the duplicate information, rather than in an unused memory location to prevent multiple entries of the same information with the resulting undesirable loss of available memory locations.
Abstract:
In a memory type tuning system having memory locations for storing information corresponding to a limited number of preferred tuning positions, a display unit normally serving to display a number corresponding to a selected tuning position is selectively caused to display the letter F when all of the memory locations contain information corresponding to desired tuning positions and the letter E when all of the memory locations contain nondesired information.
Abstract:
A container and system for holding a cutting tool of a food processing device is disclosed. The container includes a shell defining a chamber sized to receive one of at least a first cutting tool and a second cutting tool. The shell has a slot that receives a stem of the first cutting tool when the first cutting tool is positioned in the chamber and another slot that receives a stem of the second cutting tool when the second cutting tool is positioned in the chamber. The shell also has a plurality of openings that are sized to permit fluid to pass into the chamber.
Abstract:
In a cathode ray tube, plural electron beams are directed towards a faceplate biased at screen potential and are magnetically scanned by a non-self-converging deflection yoke across the faceplate to impinge upon phosphors thereon to produce light depicting an image. The plural electron beams are substantially converged near two opposing edges of the faceplate. A processor changes the raster of the image from a first raster corresponding to position of the image to a second raster corresponding to the position of the plural electron beams on the faceplate. One or more electrodes between the tube neck and the faceplate are biased above and/or below screen potential to deflect electrons landing near the periphery of the faceplate.
Abstract:
Synchronization of a source of computer controlled video to a video disc player for interactive application is obtained by sensing when the computer vertical sync leads that of the player and gating out a number of computer clock pulses equaling one video line during a period of one or more video lines. Horizontal synchronization is disabled during the vertical acquisition mode and then is established by modulating the computer clock frequency with a line rate phase error signal obtained from both video sources thereby providing rapid synchronization within approximately two seconds under worst case conditions.
Abstract:
A transparent touchbar or touchplate is supported at its edges by a plurality of push-button switches. A plurality of valid touchpoints exist; and the touching of each can be distinguished, though the number of touchpoints is larger than the number of pushbuttons. This is done by logically combining the responses to the push-button switch closures occasioned by the application of force to any one of the valid touchpoints.
