Title: Pattern synchronizing circuit
Inventor: TAKAHASHI TOSHIRO
IPC: H04J3/06
Filed: 1991-06-04
Abstract: ABSTRACT OF THE DISCLOSURE         An Nth one of N parallel sequences of low-speed data demultiplexed by a demultiplexer from high speed input data in synchronization with a high-speed clock is compared by N comparators with N parallel sequences of reference patterns.  The N parallel sequences of reference patterns are each generated in synchronization with a frequency divided clock obtained by frequency dividing the high-speed clock into 1/N.  When any of the comparators provides a disagreement output at least once, one clock pulse is eliminated by a post-clock eliminating circuit from the divided clock so that the N sequences of reference patterns are each delayed by one bit.  When it is detected by a counter that any one of the comparators does not provide the disagreement signal for n consecutive bits, the sequence of reference pattern corresponding to this comparator and the Nth sequence of low-speed data are in synchronization with each other. Clock pulses of the number corresponding to the line position of the synchronized sequence of reference pattern are eliminated by a pre-clock eliminating circuit from the high-speed clock which is applied to the demultiplexer.  By this, line positions of the N parallel sequences of low-speed data are sequentially shifted so that the Nth sequence of low-speed data assumes the same line position as that of the synchronized reference pattern, and as a result, the N parallel sequences of low-speed data are synchronized with the N parallel sequences of reference patterns, respectively.

Title: Earth duct tunnel enlargement apparatus and method
Inventor: BERGEY MICHAEL J
IPC: F16L55/18
Filed: 1991-10-24
Abstract: ABSTRACT OF THE DISCLOSURE      A method of and an apparatus for relieving ground pressure surrounding pvc vent pipes which have been displaced from their T-fitting traps in sewer systems.  The round tubular nature of a semi-rigid pipe is changed to an elliptical or oval shape with initial insertion and rotation of a special tool.  The tool being connected to a drive-shaft and rotated by an external source such as a drill motor.  The rotation of the tool within the pipe progressively causes the pvc pipe to have momentary elliptical cross-sectional shape as the tool rotates within the previously round pipe, without rotating the pipe.  As the tool passes down (or "screws down") through the pipe, the pipe re-assumes its circular cross-sectional shape, and original dia-meter, but only after its larger-dimension elliptical cross-section has pressurized the earth duct and increased its diameter to about an inch greater than its initial (unpressured) circular diameter.  The tool includes angled rollers for exerting pressure against the interior wall of the pvc pipe to reduce friction between the rollers and the interior wall of the pipe.  While the circumference of the pvc pipe in its prior round shape and its forced elliptical shape remain equal, the maximum cross-section dimension of the elliptical shape of the pipe, caused momentarily by the tool as it is screwed into the pipe, is greater than the diameter of its circular shape, thus progressively enlarging the earth duct which surrounds the buried pipe as the tool is being operated and rotated by the drill motor.
