Abstract: A coaxial hose fitting includes an inner body including an outer end portion configured for connection to an external component, an inner end portion configured for connection to an inner conduit of a coaxial hose, and an axially extending passage through the inner body from the outer end portion to the inner end portion. An outer housing including an inner end portion configured for connection to an outer conduit of the coaxial hose and an axially extending hole through the outer housing from the inner end portion of the outer housing to an outer end portion of the outer housing, the hole being sized such that the outer housing can be telescopically moved over the inner body from the outer end portion of the inner body toward the inner end portion of the inner body. A retaining element restricts axial movement of the outer housing relative to the inner body after the outer housing has been telescopically moved over the inner body.

Abstract: A moldable plastic guard segment for use in a protective guard for a conduit such as a hoses, tubing, wire, cable, and fiber optics. The guard is receivable over the surface of the conduit and is formed as a series connection of a first guard segment and at least a second guard segment. Each of the guard segments is formed as having a generally-annular body which extends longitudinally along a central axis of the guard segment intermediate a first end and a second end defining a unit length of the guard therebetween. The body first end has an inner radial surface of a first diametric extent. The body second end has an outer radial surface of a second diametric extent configured to be receivable within the first diametric extent of the inner radial surface of the first end of an adjacent guard segment for coupling each guard segment to an adjacent guard segment in forming the guard.

Abstract: A coupling for connecting a distal end of a corrugated tube with a fitting having a forward coupling end. The coupling includes a collet receivable coaxially over the distal end of the tube and including a circumferential wall portion which extends axially from a forward first end to a rearward second end. The second end is configured as having an outer portion and an inner portion of a diameter smaller than the outer periphery of the tube. The inner portion is configured to be receivable within the root portions of the tube for retaining the collet thereon, and presents a generally rearwardly-facing compression surface. The wall portion is longitudinally dissected through the second end thereof into at least a pair of arcuate, cantilevered segments.

Abstract: A fluid coupling for connecting a corrugated tube to a fitting. The coupling includes an annular compression member having an opening therethrough which extends from a forward end portion receivable coaxially over the tube to a rearward end portion threadably engagable with the fitting to urge the tube into a fluid-tight engagement therewith. The forward end portion of the opening has a rearward first end, a forward second end defining the inner diametric extent of the opening, and an inner radial surface extending therebetween from a rearward gland portion to a forward camming portion. An annular locking member is journalled within the gland to be received therewith over the tube.

Abstract: A blade spacer for use in the cutting a length of corrugated tubing with a cutter of a variety including a rotary cutting blade rotatable circumferentially about the tubing within a plane defined by a radial axis of the blade. The spacer is mountable to the cutter coaxially with the axis of rotation of the blade for positioning the blade within a root portion of the tubing such that the radial axis of the blade is aligned within the root portion to define the plane as being generally equidistant from the side walls of the root portion and as being generally perpendicular to the central longitudinal axis of the tubing. The spacer is provided to invest the lateral surfaces of the blade centrally therewithin and as having a generally circular periphery extending radially outwardly from the axis of rotation of the blade to a bushing region.

Abstract: A high performance, real-time control sequencer is disclosed which incorporates a unique state matrix logic. This real-time control sequencer performs rapid resolution of control processed state transitions and the required control actions as a function of detected external events and the current control process state. The control sequencer's micro-instructions present event and current state data as inputs to a state matrix logic and initiate state matrix operations. The state matrix, in turn, outputs data defining and initiating the next control process state, required process control actions to be performed by the control sequencer microcode, process status, and event response or control output data. The real-time, event-driven data processor invention provides greater flexibility for reconfiguring event patterns to be detected and responses desired.

Abstract: In processing a priority queue, the elements are kept in an unsorted stack and are searched for the next highest priority element only after the highest priority element has been read from the holding register. Each time a new element is written into the queue, a comparison is made of the priority of the new element with the priority of the existing element in the holding register. If the new element has a higher priority, then the existing element in the holding register is written onto the top of the stack. Alternately, if the element in the holding register has the higher priority, then the new element is written onto the top of the stack. This assures that the holding register always contains the element having the highest priority. Therefore, a read of the priority queue by reading the contents of the holding register guarantees that the highest priority element is there and it can be accessed immediately without further searching the queue.
