Low density composite particles made of a binder and filler material are provided for use in subterranean formations. The filler includes low density filler and optionally other filler. The binder includes a polymer and optionally cement. The particles may be employed as proppants useful to prop open subterranean formation fractures. The particles are also useful for gravel packing in subterranean formations, water filtration and artificial turf for sports fields. Methods of making the composite particles are also disclosed.

A method and apparatus are provided to execute bets in an agile manner. The method and apparatus of the present invention, incorporate new functions that make easier for the bettor to enter and register wagers. Such functions are, among others: 1. Same + / -2. Delete Competitor 3. All-(All except (n competitors)) 4. Trifecta to Superfecta and vice versa (TrinuSup) 5. First place, with the respective places to move 1, 2 or 3 positions (according to the type of bet, exacta, trifecta or superfecta) 6. Third or Fourth place, with the respective places to move 1, 2 or 3 positions (according to the type of bet) 7. Original bet 8. Combine with first place (Mix 1) 9. Combine with second place (Mix 2) 10. Combine with third place (Mix 3) 11. Combine with fourth place (exclusively superfecta) (Mix 4) 12. Combine all groups (Mix All) The entering and registration of pari-mutuel wagers is made easier by means of the apparatus and method of the present invention.

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.

A method of conducting a racing series for competitors and team owners is disclosed. The racing series has a plurality of races divided into a first and second set of races with competitors racing in both sets of races. The competitors and team owners are awarded points after each race, with those points being adjusted between the two sets of races. The points of only a predetermined number of competitors and / or team owners are adjusted between the sets of races. Awards, including a championship, is awarded based on the points accumulated during the racing series.

A safety jump training apparatus designed for safely mounting on a wall to permit an athlete to safely measure their vertical leap. The safety jump training apparatus includes a jump measurement device and a rotating support to rotably attach the measurement device to a mounting plate, as well as numerous safety features. The safety features include cooperating locking pin recesses and a locking pin to secure the apparatus in either an operating position or a storage position, a lock to adjustably secure the vertical height of the measurement device, a translation resistor to control the movement of the measurement device when the lock is disengaged, a safety position limiter to ensure that the measurement device is always a predetermined distance above the ground, and a safety cover to safely contain majority of the apparatus.

A hurdle has a crossbar and a pair of vertical legs. The hurdle is designed to give way or collapse when the crossbar is struck by a user to minimize the risk of injury and thereby decrease the user's fear of injury. This is done either by splitting the crossbar into separate left and right sections, or by splitting each of the legs into separate top and bottom sections. This permits the separate sections to break apart from an aligned, end-to-end orientation which they possess in an operative position of the hurdle into a nonaligned orientation after the hurdle has given way or collapsed. An elastic member connects the separate sections and urges the sections back into their aligned, end-to-end orientation when a user picks the sections of the hurdle up and resets the hurdle.

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.

A continuously height-adjustable jump cup attachment bracket for a sporting fence to support a rail includes a jump cup carried on a bearing plate that frictionally engages a support post provided with a channel and a clamping means associated with the bearing plate. The clamping means may be selectively engaged to set the height of the rail of the fence and also to be displaced from such setting in the event of accidental downward movement of the rail in relation to the post.

An exercising device includes a main frame, a pivot bar pivotally mounted on the main frame, a stop block mounted on the pivot bar and rested on the main frame when the main frame approaches the pivot bar, two rocking bars mounted on the main frame, and two elastic members each biased between the main frame and the pivot bar. Thus, the longitudinal bar of the main frame is rested on the stop block, thereby preventing the main frame from being entirely rested on the ground due to an excessive rotation, and preventing the user's back from being injured due to excessive bending so as to protect the user's safety.

An apparatus for an a method of closing a fixed gap in an activity surface such as a turfed race-track is described. The apparatus comprises a movable turf tray having an upper surface with the same characteristics as the activity surface and means for guiding the tray into the gap so as to wedge the tray releasably in the gap and thereby to provide a substantially continuous activity surface. The apparatus can be used to provide a reconfigurable racetrack crossing with the permanent road gap in the racetrack being closeable by means of the movable turf tray. Overlapping edges of the turf tray provide a weight wedging action which provides reliable pressure joins. This also has application for creating reconfigurable turfed activity surfaces such as are used in sports stadia and the like.
