Title: High-speed time-multiplexed data transmission system
Inventor: KRAFT CLIFFORD H
IPC: H04J3/04
Filed: 1993-06-15
Abstract: A high-speed burst digital time multiplexed data system has N  parallel input data paths that are multiplexed onto a serial data path for transmission from a transmitter to a receiver. Serial transmission takes place in a short burst upon command at the transmitter. Data from the serial data path is demultiplexed back into N  parallel data paths at the receiver. The entire process is accomplished asynchronously without the aid of a clock or framing signal. In the preferred embodiment, a train of N sampling pulses is generated by two tapped delay lines, one at the transmitter and one of the receiver. The length of each sequential sampling pulse is determined by the tap spacing of the delay line, and the duration of the entire burst process is equal to the total delay of the delay line. A new burst may be initiated at any time after the completion of the previous burst. Thus, bursts may follow each other immediately or be arbitrarily spaced to occur whenever data transmission is required.

Abstract: TOTAL CONTAINMENT WELDING OF PLASTIC TUBES               Abstract of the Disclosure A pair of plastic tubes are welded together by mounting each tube in the clamp jaws of a holder.  A heated wafer is movably mounted in the gap between the tubes to cause the ends of the tubes to melt.  The melted ends of the opposed tubes are pressed into contact with each other to form a welded connection.  Each side of the wafer has a scoop to remove excess plastic material at the ends of the tubes to control the size of the weld connection.  A pair of structural cam elements is used to create a precise spacing between each set of clamp jaws for guiding the wafer to control the plastic volume of the weld.  The resulting weld is independent of rheology of plastic.  The same device could also be used for disconnect purposes by cutting through a single tube and forming two tube sections.   Unique double jaw construction is also disclosed.
