Abstract: Device for training people to a preferred posture during normal gait comprising of: at least a base for stabilizing at least one rail or post coupled to said base at least one gait regulating component, which will be arranged perpendicularly with respect to said rod or post and parallel to the floor surface, with said gait regulating component provided for defining an obstacle during the normal gait of a user to impose on the latter a predetermined movement of the foot, knee, and hip, facilitating the maintenance of the user's bust erected in a position of equilibrium, with the consequent lengthening of the pushing leg, the gradual transition of the weight of the user's body by the supporting foot posterior to that of the advancing leg, and the oscillation of the arm forward opposite to the lower limb that moves, with a final effect of a steady pace.

Abstract: A sports training agility ladder is usable in a flat ladder position with the ladder rungs on or close to the ground. The ladder may also be moved into and used in a hurdle position where a bridge or center section of each rung is raised up off of the ground. The ladder accordingly provides advantages of an agility ladder and of hurdles. Each rung may have permanently attached left and right tubes forming a frame. Left and right elastic cords may extend through the left and right tubes. The ladder is consequently easily and compactly folded up for storage and transport, and quickly and easily unfolded for use in either the ladder position or the hurdle position.

Abstract: A collapsible ladder for use primarily for athletic training and the like has a plurality of spaced-apart, substantially rigid rungs secured with collapsible connectors to a plurality of spaced-apart, substantially rigid spacers extending therebetween. In one disclosed embodiment, the collapsible connectors are strips of flexible material extending between the rungs and spacers. Another disclosed embodiment has a second set of rungs aligned substantially parallel to the plurality of spaced-apart rungs along a common central set of spacers. The collapsible connectors allow the ladder to be quickly and easily transitioned between an extended, operational position, and a collapsed, storage position.

Abstract: An exercise grid includes four running strips and four crossing strips. Each running strip connects with each crossing strip at an intersection to form a grid. The running and crossing strips comprise firm rods positioned between pliable intersections. The firm rods positioned between pliable intersections facilitates folding of the grid at the intersections for transport. Placement of the grid on a playing surface allows one to perform various drills using the spaces between the running and crossing strips.

Abstract: A sporting activity system comprising a plurality of stakes and a plurality of pods. The plurality of stakes each have a length and a cross-sectional configuration. Each pod includes a body and a member for interfacing with a stake. The body includes a lower edge, a side and a top surface. The interfacing member includes an opening disposed on one of the top and the sides configured to receive a stake, and, two channels disposed on the body spaced apart from the opening. Each of the at least two channels and the opening can accept a stake of the plurality of stakes simultaneously. Connectors may be provided releasably coupling two stakes of the plurality of stakes to each other.

Abstract: By providing a playing surface which is dimensioned for enabling a desired game to be played with all competitors positioned thereon, with the playing surface being rotated, a competitive game and/or playing system/environment is created which enables all individuals to compete equally and fairly regardless of their physical capabilities. In the preferred embodiment, the rotation of the playing surface is maintained at a constant rate of speed, although added dimensions and difficulties can be added to the game by altering the rotational speed of the playing surface during the competition. By providing a playing surface upon which any desired game can be played, particularly an action oriented game, with the playing surface being continuously rotated throughout the play of the game, forces previously unknown to each competitor are continuously imposed on each competitor, effectively rendering each competitor to possess equal capabilities, regardless of their strength, agility, proficiency, or size.

Abstract: An adjustable step trainer including two straps and more than one slat through which the straps are passed. Each end of the slat has a fixing section through which the strap is passed. A press unit is disposed in a chamber of the fixing section for pressing and fixing the strap.

Abstract: A template assembly comprising at least one marking template comprising a pair of side rails and a pair of end rails integrally connected at their ends to substantially form a rectangular-configured frame; and a plurality of marking pans situated within and fixedly attached to the rectangular-configured frame, each having a bottom facing plate and an upwardly extending wall along the perimeter thereof to substantially form a receptacle for holding and collecting marking media used in establishing the field line, the bottom facing plate comprising a rectangular-shaped opening having geometric dimensions substantially equivalent to the width and length of a field line typically appearing on a football playing surface.

Abstract: A portable obstacle course system that includes of number of child safe obstacle elements that is used as an entertainment activity for birthday parties and the like activities. The system is easily transported to the activity site, is rapidly set up in a variety of configurations and is rapidly taken down after the activities are over.

Abstract: A gauntlet athletic sled for use by football trainers has a sled frame with spaced apart side sections defining a runway between them from a front end to a rear end. A front to rear extending series of readily removable, position adjustable inflated resilient arms project from the side sections laterally into the runway to create a predetermined obstacle path simulating the arms and hands of would be tacklers, which must be deflected aside to permit passage of the runner down the pathway. The varied pressure of arm inflation controls the resistance to passage of the runner proceeding down the runway.

Abstract: A jump training device has a substantially ladder-like element including two longitudinal bar members spaced from one another in a transverse direction, and a plurality of transverse members connected to the longitudinal members movably movable in a longitudinal direction, each of the transverse members being yieldable so that when an athlete jumping over the transverse members touches a transverse member, the transverse member yields so as to prevent injury to the athlete.

Abstract: A process for the recovery of metal carbides from ferroalloys and nickel alloys of niobium, tantalum, vanadium, and hydrides thereof is disclosed. The selected ferroalloy or nickel alloy is contacted with a hydrogen containing gas, subdivided, and carbided by contact with a hydrocarbon containing gas at a temperature above 500.degree. C. The carbided reaction product is then leached with an aqueous acid solution for recovery.
