Abstract: ABSTRACT OF THE DISCLOSURE      A welding sleeve has an inner body with a grooved outer surface, a surrounding outer body and a resistance heating wire therebetween.  The inner wall, between the bottoms of the grooves and inner surface of the inner body, increases in thickness toward the axial center of the sleeve.  During welding, the center of the sleeve and the adjacent axial ends of the parts to be joined are heated later than the axial ends of the sleeve, thereby increasing the stability of the joint formed.          Also, disclosed are improved mold assemblies for forming the welding sleeve.

Abstract: Abstract:           A microprocessor based, digital to digital converting, full duplex time division multiplexing data set operating in burst mode transmission interfaces a data terminal to a communication path for communicating with another data terminal. The data set includes a transmitter, a receiver, a controlled transmit/receive switch, digital logic control circuitry, and a microprocessor for communi-cating with and controlling the other elements thereof.          Communication is based on a bipolar code, and bipolar vio-lation encoding is used to signal special messages.  Control words, indicated by bipolar violations, are generated within one data set and transmitted to another data set as a preamble to a bipolar violation for communicating information to, and controlling oepration of, the other data set.  Special start and stop bits are generated by the data set before and after each fixed length data block for clock synchronization and DC balancing, and are stripped from the data clock by the receiving data set.  Circuitry is also provided for generating a DC balance bit within each preamble to a bipolar violation.  Specific logic circuits and control programs cooperate in providing system operation.

Abstract: ABSTRACT OF DISCLOSURE            A shear connection truss construction is disclosed that exhibits no bending moment or horizontal reaction when the construction is mounted on vertical support columns.          The truss construction utilizes truss members attached to each other having essentially I-shaped cross sections defined by parallel, longitudinally extended flanges, and a connecting web extending transversely between them.          Each truss member defines a unitary, unsplit end and a longitudinally split end, defined by an upper chord located in the same directional plane as the unsplit end, and a lower chord extending at an acute angle with respect to the upper chord, the lower chord having associated therewith a portion of the web that is dis-continuous with the web of the unsplit end.  Preferably, the unsplit end of the truss member has a length ranging from about 15% to about 35% of the total length of the member, and the acute angle subtended between the upper and lower chords may range from about 5° to about 15°.          The truss member may be prepared from a unitary I-beam, or from flat component parts that are assembled to form the final member.  Also, a lower flange of the truss member may be smaller in size than the upper flange.          The ease of construction and constructural stability of the present truss member and truss construction confers economies in fabrication and use.  The present truss member and truss construction are particularly well suited for use in the construction of wide-span building structures.
