Abstract: A rebar anchorage system for a horizontal lifeline is described as well as the method of installing the same. Preferably, two triangular frames are secured to vertically extending rebar by eight sets of J-bolts and speed nuts. The frames are preferably made of tubular steel, and may be attached to the vertically extending rebar by one workman. Two or more rebar lifeline anchors may be used in combination to secure the ends of a horizontal lifeline. Three or more anchors can be used to secure two or more lifelines that are perpendicular to each other, such as along the outer, leading edges of a construction site.

Abstract: A shock absorbing lanyard having an integral fall arrest energy absorber formed in a one-piece woven, knitted or braided construction wherein partially oriented yarn (“POY”) fibers and high modulus yarn fibers are combined integrally in one section and are separate in another section in which the high modulus yarn fibers preferably form a sheath around a core of POY fibers.

Abstract: An apparatus and method for temporarily anchoring a horizontal lifeline to existing rebar extending from concrete. Preferably, two triangular frames are temporarily secured to vertically extending rebar by eight sets of J-bolts and speed nuts. The frames are preferably made of tubular steel, and may be attached to the vertically extending rebar by one workman. Two or more rebar lifeline anchors may be used in combination to secure the ends of a horizontal lifeline. Three or more anchors can be used to secure two or more lifeline that are perpendicular to each other, such as along the outer, leading edges of a construction site.

Abstract: Presented is a golf course having a single fairway of conventional length common to at least three putting greens and cups, the course having a Tee area designated for use in connection with the three putting greens and cups, and a set of balls that are color coded in correlation to the green to which they are to be played. The Tee area is also delineated to provided specific areas from which golf balls are driven to the various greens, these areas also bearing indicia correlated to the green to which golf balls are to be played. In addition to being color coded, the balls are also marked with indicia indicating the sequence in which they are to be hit, and indicia indicating the golfer to which the balls belong. The course, the set of golf balls, and the method of play thus permit the completion of nine or eighteen holes of golf in a short time span in comparison to conventional golf courses.

Abstract: Presented is a portable catapult device for hurling a succession of simulated baseballs for the purpose of affording novices in the game of baseball an opportunity to swing at the simulated baseball to thereby increase their proficiency at batting. The device includes a base on which is mounted a carriage that is reciprocable by engagement with an endless chain, and a sling mounted on the base through use of elastic bands selectively connected to and disconnected from one end of the reciprocable carriage so that the elastic bands are stretched a predetermined amount and when released carry a ball-impelling member that engages the ball and impels the ball from the device at a predetermined velocity and in a predetermined trajectory that carries the ball toward the batter.

Abstract: Presented is a method and apparatus that permits a skier to control the speed at which he descends a ski slope. In terms of structure, the invention includes a pair of probes mounted on each ski that protrude below the running surface of the ski and thereby drag in the snow. The probes may be controlled as to the depth of penetration of the snow either before the skier starts his run, or during his descent. Having deployed the probes, added manueverability control is achieved merely by conventional body movements which affect the depth to which the probes penetrate the snow.
