Abstract: The present invention relates to a radiation monitoring device which is utilized to measure the voltage supplied to an x-ray generator of an x-ray machine in terms of kVp units. The device includes a pair of detectors which are simultaneously exposed to an x-ray beam. The x-ray beam is filtered by a first amount before being supplied to the first detector, and is filtered by a second amount, greater than the first amount, before being supplied to the second detector. Both detectors generate an output signal having a magnitude proportional to the amount of radiation energy received. The ratio between the detector output signals is proportional to the amount of voltage supplied to the x-ray generator. The output signal of the first detector is an input to a first integrator which generates a voltage ramp output signal as an input to a trigger circuit. The output of the second detector is supplied to a second integrator which generates a second voltage ramp output signal as an input to a sample/hold circuit.

Abstract: The invention disclosed concerns a method of selecting a standard glove size. The method includes the steps of selecting a pair of two dimensional measurements which are correlated to hand volume, dividing a population of hand volumes into a predetermined number of approximately equally populated subgroup ranges, plotting two dimensional chart areas for each subgroup based upon intersections of the selected two dimensional measurements with reference to a predetermined point on the chart, and assigning one of the standard sizes to each chart area. The method further includes the steps of placing a hand on the predetermined point and plotting the intersection of the pair of two dimensional measurements for the hand to select the proper standard glove size. The chart can include areas for both left and right hands and the predetermined point can abut the web space between the middle and index fingers on the hand.

Abstract: A battery tester adaptable for testing both 1.5 and 9 volt batteries is disclosed. The tester includes an indicator lamp carried by an arm extending over a base which receives the battery to be tested. The arm is attached to a plunger, vertically slidable within a stem connected to the base. A bias spring urges the arm to an uppermost position on the stem. Conductive means on the base, stem, plunger, and arm provides a partial circuit between the lamp and a first pole of a cylindrical 1.5 volt battery in contact with the base. A resistive terminal is attached to the arm near the indicator lamp. Depression of the arm from its uppermost positions places a protruding terminal on the lamp in contact with a second pole of either a cylindrical or rectangular battery. Such depression of the arm also places the terminal secured on the arm in contact with a first pole of a rectangular battery. Thus, a circuit is completed between either type of battery and the lamp.

Abstract: A sled for use in tractor pulling contests, and the like, comprising a frame supported on front and rear wheels, a ballast mass supported by the frame, a pan adapted for sliding frictional engagement with the ground, and an articulated linkage mechanism for transfering the weight of the ballast from the wheels to pan. As the sled is pulled, the linkage mechanism, which is driven by rotation of the rear wheels, progressively shifts the weight of the sled from the wheels to the pan, by lowering the pan relative to the frame. The suspension springs for the rear axle have a greater vertical stroke than those for the front. Therefore, although the front wheels may ultimately be completely lifted from the ground during the weight transfer, the rear wheels always contact the ground with a force sufficient to drive the linkage mechanism. suBACKGROUND OF THE INVENTIONTractor pulling contests have become increasingly popular.
