Abstract: A system for recovering information from a videodisc and performing special functions which enhance the operational character of the system. To increase the reliability of landing at or near a target track, provisions are made to search for a track adjacent a target track whose track identifier has been obliterated. Further, a method and means for stepping forward or reverse one field at a time is disclosed. Another aspect of the invention concerns a capability to respond to a random command instruction resulting in subsequent functioning of the system in a random manner. Yet a further aspect of the invention is related to controlled jumping of one or more tracks during vertical blanking time to produce unique forward or backward motions; multiples of playing speed, both forward and reverse, and visual special effects can be realized using the multiple track jumping feature. Finally, a method and means are described which permit synchronous transmission of video from a videodisc to an external using device.

Granted: 1988-06-30
Abstract: An apparatus and method is provided for packaging a fibrous, preferably compressible material; such as mineral fiber insulation shapes, in which the method and apparatus provides for delivering one or more such shapes (which are preferably rolls) through a staging area to a compression chamber in which they are compressed from a generally cylindrical shape or roll (or rolls) of a first diametral size, to a roll (or rolls) of a second, reduced diametral size, with the roll then being discharged from the compression chamber and being secured to substantially retain the cylindrical configuration of reduced diametral size, preferably by means of a sleeve or the like placed thereover. The operation occurs with a minimum of operator assistance, and may optionally be effected to occur automatically. The package formed may be of various roll lengths, and to this end, in the staging area prior to the compression chamber, the number of rolls that will be simultaneously compressed may be determined. Individual ones of the features are separately presented, such as the compression chamber, which employs a double stage compression, and a discharge arrangement that provides particular efficiency.

Abstract: A stringing system for a racket consisting of two elements, a prewoven net of individual strings and a two piece fixing device, acting as a string clamp in the string hole of a racket frame under the string's own tension. A first member of the fixing device is tubular in shape and is designed to extend through the interior of the racket frame hole. Its upper portion extends outward from the frame hole and has a slot which separates it into two half shells. A second member of the fixing device is placed over the frame hole and is located entirely exteriorly of the hole. The exterior surface of the second member is adapted to the profile of the racket frame. During stringing of the racket, the first member is placed inside the second member and into the frame hole. The string is passed through the hole in the first member, such that when the first member slides into the second member, its two half shells are pressed together around the string to hold the string in place when under tension.
