Abstract: A model, a counter, an actuator, and a termination device is provided. During a rest state the model is stationary in a first position and the counter is not counting. During a first transition state the model moves from its first position to a second position in response to actuation of the actuator and the counter begin counting. During an operation state the model is stationary in a second position and the counter is counting. During a second transition state, in response to a termination device the model moves from its second position back to its first position and the counter stops counting. A timing mechanism is provided for controlling the duration of the operation state. The counter can be any type, such as a dial counter, digital counter, or analog counter. The actuator may also activate a music box.

Abstract: A special purpose calculator for determining the optimum degree of flexibility for a matched set of golf clubs, tailored to the driving capability of the individual golfer. The calculator first correlates the effective driving capability of the individual to an empirically determined optimum flexibility index, which index is based on a standard club length, hosel length, tip insertion depth, and swing weight of the golf club. The calculator next compensates for desired differences, in for example club length and swing weight, to determine a shaft with a compensated flexibility index which will provide the same "feel" as the standard club. The calculator can then also be used to determine the requisite head weights, both wood and iron, as a function of desired club length and swing weight so as to provide the proper flexibility for that individual. For optimum results, the flexibility index is determined by measuring the vibration frequency of the shaft.

Abstract: This computer device provides a system for selecting the winners of both horse and dog races, and it consists primarily of a stationary card, having a circular area, in which is imprinted the weights of the horses and dogs, as indicated on track programs. It further includes a rotatable disc, with openings to view the weights of horses and dogs, and the program "odds" are imprinted alongside of each of the openings, the bet selection being the lesser sum of the addition of each of the weights of the horses and the last figure of the "odds" on each horse, the same being applied to dog races.

Abstract: A device for enabling a golfer to determine the proper length of putting stroke according to the distance between ball and hole and according to the lie of the ball. The device comprises a plurality of scales representing relationships between putting strokes and putt distances for various lies. According to visual estimates of the distance and lie of a ball, be it flat, uphill, downhill or sidehill, a golfer may read out from the scales the corresponding putt stroke and aim necessary to hole a putt of any distance and lie.

Abstract: A calculating device and a mechanical method of calculating win, place and show odds for events such as horse races having pari-mutuel wagering systems. The apparatus includes a base member and a pair of slideable members laterally displaceable relative to the base member. A transparent cursor having a hairline located thereon is also laterally displaceable relative to the base member and to the slideable members. In an alternative embodiment, the members and the cursor are rotationally displaceable relative to the base member. The device is arranged so that indicia on a first scale which represent the amount in a wager pool of interest may be positioned relative to a second scale so that the hairline on the cursor may be adjusted to the amount bet on a horse of interest. The win odds of the horse of interest may be directly read beneath the cursor on a third scale and those odds may be calculated in terms of dollars returnable for a given bet on a fourth scale.
