Abstract: A PIPE COUPLING Abstract of the Disclosure A pipe coupling is disclosed which is capable of being periodically coupled and uncoupled between two lengths of pipe. The pipe coupling includes a first and a second union which are fixed between an intervening length of pipe such that the intervening length of pipe does not have to be of a precision length.  The outer periphery of one end of the pipe contains serrations and this end is fixed to the first union by a serrated compression ring and a backnut.  By tightening the backnut onto the first union, the compression ring firmly engages the serrations on the pipe and prevents axial movement thereof.  The second union includes a non-binding compression ring and a backnut as well as having an internal elongated bore of approximately the same diameter as the outer diameter of the pipe.  As the backnut is tightened onto the second union, the compression ring is squeezed about the outer periphery of the pipe and forms a seal therewith.  One benefit of this second union is that it can be repeatedly coupled and uncoupled relative to the pipe to permit the intervening length of pipe to be moved into or out of the second union as the need arises. The second union also permits a tight seal to be formed even when a limited amount of misalignment exist between the pipe and the second union.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to a process for polymerizing in an gaseous  phase using heterogeneous catalysis and to a spherical reactor for carrying out said process. At least one monomer which is gaseous under the reaction conditions is just in contact with a solid catalyst in an agitated polymerization zone. The polymerization zone is defined by a spherical wall and the agitation is ef-fected by means of a turbine unit having blades driven in rotation. The blades extend alongside the wall on 10 to 60 % of its surface. The particles of the catalyst and the growing polymer powder are driven by centrifugal force onto at least a part of the spherical wall and fall back into the central part of the spherical zone, thereby ensu-ring an thorough and uniform mixing without any dead zone.          The invention is useful for prepolymerizing or polymerizing olefins.               BACKGROUND OF THE INVENTION               Field of the invention The invention relates to the field of polymerization in a gaseous phase with the use of heterogeneous cataly-sis. It more particularly relates to a process and a reac-tor for carrying out such polymerization reactions.    Many monomers may be polymerized in a gaseous phase with heterogeneous catalysis. This is in particular the case of unsaturated ethylenically insaturated hydrocarbons and in particular olefins. For the homopolymerization as well as the copolymerization reactions, the monomer is put in contact in the gaseous form with a catalyst dispersed

Abstract: ABSTRACT OF THE DISCLOSURE         Communication between portal units and identification tags is accomplished by continually radiating an interrogation signal consisting of a code pattern from each portal unit followed by a listening interval.  Tags within range of such interrogation signal test the incoming signals for frequency, bit duration, bit rate, a preamble code and a facility identifying code.  If the tag receives a valid signal to which it has been preprogramed, such signal synchronizes and initiates a plurality of tag re-sponses within a given overall response interval and with each response transmitted during randomly selected time slot.  Each tag is provided with its own pseudorandom binary sequence generator and reply counter with the pseudorandom generator sequenced by a signal derived from the carrier signal radiated by the tag.          The portal units also test incoming signals for fre-quency bit rate and bit duration as well as for a preamble code generically indicative of a tag. If the test is passed, the remaining tag response consisting of an identifier and an error correcting code is accepted and passed on to a CPU.
