Abstract: A method of assessing the biomechanical efficiency of a pitching delivery relative to time elapsed through certain motions of the pitching delivery. The method includes a pitching delivery timeline. The pitching delivery timeline has a first time requirement between 0.95 and 1.05 seconds within which a first forward movement until a foot strike range of motion should be completed. The pitching delivery timeline has a second time requirement between 1.25 and 1.35 seconds and corresponds to the time it takes to complete the first forward movement and a ball release range of motion. The pitching delivery timeline has a third time requirement from between 1.925 and 2.025 seconds and corresponds to the time it optimally takes to move from the first forward movement to a follow through range of motion. The method includes comparing at least one of the time requirements with a pitcher's delivery time for the corresponding range of motion.

Abstract: A starting pad, a landing pad and a target are spaced along a beam. The device may be used to train an athlete, such as a baseball pitcher, to accurately repeat a sequence of coordinated leg, arm and torso movements. The athlete stands on the starting pad and grips a suitable striking implement, such as a hand towel. The athlete executes a sequence of movements in the manner required by the sport, beginning with the athlete stepping off the starting pad and ending with the athlete stepping onto the landing pad. During the movement sequence, the athlete swings the implement in the manner of the sport to which the sequence pertains and attempts to strike the target with the implement. For example, a baseball pitcher begins a delivery with a leg lift on the starting pad and strides to the landing pad while swinging the implement as though it were a baseball in an attempt to strike the target.

Abstract: A traveling suction floor cleaner for cleaning textile mills and adapted for periodic removal of textile waste material collected by the cleaner, and comprising a suction blower fan; means for causing said suction blower fan to travel adjacent one or more textile machines; a housing for enclosing said suction blower fan; suction duct means communicating with the housing and arranged for carrying suction air and entrained textile waste material from the floor of a textile mill to the suction blower fan; the suction blower fan, the housing and the suction duct means defining a suction air path; filter means having filtration surfaces positioned within the suction air path for receiving entrained textile waste material while permitting air flow therethrough; and means for moving the filter means for successive presentation for filtration of clean filtration surfaces on the filter means to collect textile waste from the suction air path and means for concurrent successive presentation for waste removal of filtrat

Abstract: A plurality of traveling pneumatic cleaners for respective groups of textile machines cooperate with respective unloading stations for transferring fiber waste from collection chambers of the traveling cleaners into the unloading stations. All the unloading stations are connected, via normally closed valves, to a common source of suction, and according to the method and apparatus of this invention, provision is made for controlling the opening of the valves for the respective unloading stations so that only a single one of the valves may be opened at any given interval of time, thus minimizing the amount of suction required at the source for effectively transferring the fiber waste into the unloading stations. Further, a normally closed door for the collection chamber or chambers of each traveling cleaner is controlled so that the opening of each such door may be effected only at times when the valve of the respective unloading station is open.

Abstract: A noise abating enclosure is positioned beneath and movable with the overhead-mounted blower fan housing of a traveling pneumatic cleaner, and is provided with an upwardly opening air flow inlet passage in a medial portion thereof which communicates with the inlet opening in the fan housing. The enclosure also is provided with one or more stacks projecting upwardly from outer portions thereof and adjacent the fan housing so that air flows downwardly from generally above the traveling cleaner and into the stacks at locations spaced from the machines and operators below the fan housing of the traveling pneumatic cleaner so that impingement of noise generated by the air streams onto operators is minimized.
