Abstract: An apparatus as provided for measuring acceleration of a person's head or other object. The apparatus comprises a sensor for sensing acceleration and a controller for controlling recording of data resulting from the sensed acceleration due to an explosive force. The controller is adapted to determine whether or not to enable recording of the data based on the sensed acceleration. A data receiver is provided to receive the sensed acceleration data from the sensing means, and requires electrical power to enable data to be received thereby. The controller controls electrical power to the receiver so that if the sensed acceleration reaches or exceeds a predetermined value, electrical power to the data receiver is enabled. The recorded acceleration data may be used for injury analysis.

Abstract: A manual device, for use in a stand, provides a threaded rod with two opposed cones coaxial upon the rod. The cones have wider bases located outwardly from the center of the rod and narrow tops located inwardly. Threaded holes centered in the tops of the cones admit the rod. In use, a wheel is placed upon the rod and the cones are turned towards the wheel, points toward the wheel. As the cones engage the wheel, the angled surface of each cone guides the wheel to be centered upon the rod. For open hubs, one cone is reversed so the base contacts the wheel while the top of the other enters the wheel hub and the base. When finger tight, the cones secure the wheel to the rod without marring for spinning and balancing on an axis coaxial with the rod.

Abstract: A method and system for balancing a rotary member. The system preferably comprises balancer stand, a stator element including and a levitation element. The rotary member is coupled with the levitation element. The rotary member and the levitation element are positioned above the stator element which preferably comprises a superconductor element. The rotary member and levitation element are suspended above the stator element when the superconductor element is activated through field cooling. The rotary member is titled with respect to a direction of gravity such that an imbalanced portion of the rotary member rests at the lowest point of the rotary member. The imbalanced portion is thereby identified and can be corrected.

Abstract: A blade balancer qualitatively determines imbalance of a lawn mower blade. The blade balancer comprises a tube that rotates on precision bearings about a horizontal axis. A sphere is slidingly captured in one end of the tube concentric with the axis of rotation. A spring biases the sphere partially out of the tube. The mounting hole of a lawn mower blade is placed over the sphere, and the lawn mower blade is pushed against the sphere to slide the sphere into the tube inner diameter until the blade contacts an annular magnet secured to the tube and surrounding the sphere. The blade is thus accurately located for rotation about the horizontal axis. Gravity rotates the lawn mower blade, tube, and sphere together to place any unbalanced mass of the blade at a lowermost point under the horizontal axis. In a modified embodiment of the invention, the sphere is replaced by a plug having a cylindrical section that is slidably captured in the tube inner diameter and a conical section.

Abstract: The wheel balancer includes a plastic one-piece body for mounting on the shaft of a wheel and also having a window. A bar is carried by the body and is slidable therein to a position where the wheel is in balance, whereupon indicia on the bar, visible through the window, informs the mechanic how much weight is to be added to the wheel to place it in balance. The bar is also rotatable about its axis, in the body, so that several labels corresponding to several wheel diameters can be provided on the same bar. A detent mechanism on the body and on the bar holds the bar in a selected rotational orientation while enabling the sliding movement during balancing.

Abstract: The nose unit is formed by a hollow body of revolution having an annular flange and attached to a rotatable spindle. A series of crank-plates provided with studs for securing the rim of a vehicle wheel can be pivotally mounted on the annular flange. The crank-plates can then be positioned correctly by means of guiding grooves formed in a disk which is rotatably fitted within the annular flange. A cup acted upon by a spring is housed within the interior of the hollow body and cooperates with a cone for centering a wheel rim having a central bore. Vehicle wheels having rims of the central bore type or of the closed type can be balanced without any need for preliminary disassembly of the disk or of the cup, the centering cone being introduced either on the front side or on the rear side of the rim.

Abstract: A bowling ball weighing device is provided for determining weight imbalance between various opposed sides of bowling balls comprising a support stand having two substantially vertically oriented standards supporting a circular cradle freely and pivotally therebetween for free rotation of the cradle about an axis of rotation extending between the standards. The cradle is adapted to receive a bowling ball therein, with the geometric center of a bowling ball lying in a vertical plane which includes the cradle axis of rotation and which divides the ball into opposed sides. An elongate indicator is securely attached to the cradle and registers on an indicia carrying field attached to the support stand the degree of weight imbalance between the opposed sides of the bowling ball.

Abstract: The static balancing of a wheel is achieved quickly and in a simplified manner with the use of a scale device which is mounted alongside a rotatably mounted wheel. The scale device comprises an elongate deflectable pointer which is mounted at one end and extends in a cantilever manner alongside the wheel. A scale is mounted alongside the elongate deflectable pointer and indicia is provided on the scale indicating the amount of weight needed to be added to the wheel in order to bring the wheel into balance. A finger is provided which is adapted to be secured to the wheel at a selected circumferential location in relation to the heaviest point on the wheel and having a portion projecting laterally from the wheel for engaging and deflecting the pointer whereby the amount of deflection of the pointer can be read directly from the scale and the amount of weight needed to bring the wheel into balance can be readily determined, thus greatly reducing the amount of time required for balancing the wheel.

Abstract: A wheel mounting assembly for a tire balancing machine of a type for rotating a wheel with a tire mounted thereon includes an annular support plate arranged to be mounted for rotation by the machine. The support plate carries means for simultaneously moving a plurality of studs uniformly between first and second radial positions defined about the axis of rotation of the support plate. The foregoing means includes a central gear disposed on the axis of rotation of the support plate. A plurality of satellite gears corresponding in number to the number of the studs needed for support of a given wheel are disposed about the axis of rotation of the plate in engagement with the central gear. The studs are carried on means supported from each satellite gear so as to revolve about the axis of rotation of the satellite gears whereby rotation of one of the satellite gears serves to rotate the others to the same degree via the central gear so as to move all studs simultaneously from the first to the second position.

Abstract: Method and apparatus for single plane, balance determination of cylindrical parts and the like, particularly adapted for use with determining imbalance of unmounted tires. The tire to be tested for balance is supported for rotation about a horizontal axis and driven in a substantially constant slow speed while torque monitoring means generates an output proportional to the variations in torque resulting from driving of the support means, electrical signal conversion means determines the magnitude of imbalance as being one half the difference between the maximum and minimum torque output values which is shown on a visual output display. A marking device is triggered to indicate the position on the tire at the instant the maximum torque output occurs to locate the position of the center of gravity on a horizontal line moving upward around the rotation axis.
