Abstract: A tubular connector system for joining two pipe ends without the necessity of rotating the pipe ends. A coupling has opposing tapered ends. Each of the tapered ends slopes inwardly from an inner extent to an outer extent to form a respective mouth opening of the body. Each tapered end of the coupling has a contoured surface which is made up of a series of alternating helical spline wedges. The wedges are oppositely tapered from an inner extent to an outer extent, whereby the helical spline wedges form an alternating series of lands and grooves on the body as viewed from the respective mouth openings. The two opposing pipe ends have mating engagement surfaces which engage and mate with the contoured surfaces of the coupling as one pipe end is pushed toward the other during assembly.
Abstract: An interactive boxing training device is made up of an inner tube, an outer tube and a fluid propulsion system for propelling the outer tube outwardly along a generally horizontal axis in a stroke defined between a retracted position and an extended position, upon demand. A retraction system returns the outer tube to the retracted position after each stroke. The inner tube is mounted in a housing at a pivot point which allows 360 degrees of freedom of movement. The housing is itself mounted on an upright rail which allows the housing to have a vertically adjustable height. The retraction system is made up of one or more elastomeric elements which are stretched as the outer tube moves to the extended position and which are relaxed as the outer tube moves back to the retracted position. The housing is also removable from the upright rail so that the device can be pointed at a boxing trainee in order to simulate punches thrown at the boxing trainee.
Abstract: This discovery is storable, pre-nascent iodine that activates and: produces nascent iodine over a two-to-three-hour period within the body when diluted in water and consumed. The iodine is in a low concentration in a tincture of grain alcohol. A quantity of tincture is submerged in a glass container in an electrolytic bath between two electrodes and subjected to a specific amperage for a period of time. This action causes the diatomic bond of the iodine molecule to be broken with the iodine atom receiving excitation energy from the magnetic field. When diluted and consumed into the body, the nascent iodine is able to produce significant beneficial effects in the body.

The accessory device includes a walking plate which connects to one of the fixator frame components for supporting the sole of a patient's foot. The accessory device also includes a companion shroud which is wrapped about the fixator with the fixator being received within the interior of the shroud. The shroud has a width and height which are sufficient to conceal the fixator within the shroud interior. The shroud has fasteners which allow it to be easily installed and removed from about the fixator.
Abstract: A method for reducing the deleterious effects of sulfate reducing bacteria in aqueous environments, particularly those in which metal materials are exposed to the microorganisms. A treatment solution containing rotenone is introduced into the aqueous environment. The rotenone is present in the treatment fluid in an amount which is sufficient to inhibit the growth of sulfate reducing bacteria on the metal material.
Abstract: A thread form is shown which is used to make a threaded pipe connection capable of being screwed together and subsequently unscrewed. A pin member has external threads with stab flanks and load flanks and flat crests and roots for mating with the mating internal threads of a box member to make up a pipe connection. The stab flanks and load flanks form a distinct geometric profile which is arrow-shaped when viewed in profile. The arrow profile can be cut in either of two opposite directions. Each profile includes only two facets with the facets on the stab flank and the facets on the load flank both leaning in the same direction with respect to the longitudinal axis of the pipe, when viewed in profile.
Abstract: An improved rail car is pulled by an engine for transporting coal or other porous dust bearing materials. The car has opposing long sidewalls and opposing shorter end walls, which together define an initially open interior, a bottom and an open top. The open top of the car is covered by at least one pair of main doors in the form of opposing hinged A-frame sections which are pivotable between a closed, transport position and an open loading position which exposes the rail car interior for loading. The A-frame sections also have longitudinally spaced edges which are spaced apart to form a discharge door opening. A discharge door is located in each of the discharge door opening and is pivotally hinged within the respective door opening so that it opens under the influence of gravity in a rotary dumping operation. The discharge doors, together with the A-frame sections, form a door-within-a-door operating configuration.

Abstract: A combination sealing and restraint system for an as-cast ductile iron fitting is shown for both sealing and preventing separation of an iron pipe fitting and a mating male pipe. A ring-shaped body is installed within a mating groove provided in a mouth region of the as-cast fitting after the fitting has been cast at the manufacturing plant. The ring-shaped body is formed of an injection molded elastomeric material and carries a series of gripping segments which have teeth on an inner surface thereof which are designed to engage an outer surface of a mating male pipe. The teeth are oriented to allow movement of the male pipe in a first direction relative to an end opening of the fitting during assembly, but to resist movement in a opposite direction after the fitting joint has been assembled. The gripping segments have shelf regions which are mechanically secured to the elastomeric body of the gasket.
Abstract: A wound treatment-dressing is shown which includes a dressing body formed from a medically inert, moisture permeable, urethane open-cell foam which is hydrophilic in nature. The foam body has a foam matrix of interconnected foam cells with cell walls which have incorporated therein a combination of inorganic antimicrobials as active agents, the active agents being incorporated into the foam matrix both topically on a foam cell surface and integrally within the foam cell wall. The antimicrobials are manufactured in a selected particle size range which improves predictability and performance of the wound dressing.
Abstract: Calco-magnesian aqueous suspension having particles of solid matter with, before being put into suspension, a specific surface area, calculated according to the BET method, which is less than or equal to 10 m2/g, and its method of preparation. Such an aqueous suspension of calco-magnesian solid matter can achieve a very low viscosity, making it possible to greatly increase the solid matter concentration of the suspension, or again to reduce the size of the particles in suspension, thus obtaining a concentrated and reactive milk of lime.

Abstract: A method and system for cleaning the perforations of well casings employs a non-rotating tubing string attached to a hydraulic jet carrier body. The carrier body has outwardly extending arms which terminate in spray nozzles, each of the nozzles expelling a stream of fluid under pressure against the well casing with an inertial force. The nozzles are oriented on the carrier body such that the reactive force for each jet is directionally offset with respect to the central axis of the carrier, thereby creating a twisting moment tending to rotate the carrier body about its central axis. The nozzles are located a fixed distance from the carrier body which is between about ½ and 1½ inches from the well casing perforations in use.
Abstract: A window frame assembly for installation within a garage door having front and rear exposed surfaces and one or more window openings. The assembly includes front and rear window frame members which are installed within the door opening on the front and rear exposed surfaces. The front and rear members are brought toward each other to sandwich the borders of the door panel defining the window opening and while also capturing an associated transparent pane. The rear frame member has a rib formed about an inner peripheral edge which is received in locking engagement within a cooperating peripheral groove provided on an inner side of the transparent panel. The rib and groove locking arrangement transfers impact forces on the pane to deformation forces on the front and rear frame members. A series of fastening members are used to hold the front and rear frame members securely against each other.
