摘要： A balance mechanism for automatically lifting known weights in a single-arm balance comprised of two plates, a first plate supporting the known weights and a pan for an unknown mass to be weighed and a second counterbalancing plate coupled to the first through a box lever having diagonal corners connected to a support member through flexible elements that will permit the box lever to pivot about a diagonal axis in response to a vertical force at one free corner connected to a corner of one balance plate or in response to a vertical force at the other free corner connected to a corner of the other balance plate. One balance plate is secured in space by two taut rectangular loop lines, one line being connected taut to diagonally opposite corners of the plate and to elements affixed to the support member in a position over the free corners of the plate, and the other line being connected taut to the free corners of the plate and to elements affixed to the support member in a position over the other two corners. The other balance plate is secured in space parallel to the first plate in the same manner as the first plate by two taut rectangular loop lines, but relative to the first plate as the support member and oriented 90.degree. from the first plate about an axis normal to the plates. Any force on one plate is coupled to the other plate by the box lever to cause the plates to move in opposite directions while the two pairs of taut lines maintain the plates substantially parallel regardless of whether or not the plates are horizontal or the force is normal to the plates.

摘要： A spring balance with a horizontal scale, which comprises a housing, and a weighing pan which is mounted to perform a substantially vertical movement upon placing a weight on the weighing pan, and includes a support and a drive pin disposed at its end. A pointer is movable in a horizontal direction and indicates the weight on a scale. A device for converting the vertical movement of the weighing pan into a horizontal movement of the pointer. The converting device includes a deflection wheel which has a radial slot receiving the pin and is mounted in the housing. A spring is engaged to and holds the weighing pan in its starting position and serves as standard of comparison.

摘要： A system for determining remotely the distance from the bottom of a storage tank to the liquid-vapor interface of the stored liquid utilizing a pair of solid state electrical sensing elements whose electrical resistance varies as a function of element heat dissipation capable of providing continuous extremely accurate digitally displayed measurement information referenced to the bottom of the tank even when the stored liquid and vapor are at the same temperature. The solid-state electrical interface sensing elements are affixed at the end of a vertically suspended motor driven cable disposed within the storage tank which is coupled to a DC pulse activated stepping motor and a master control circuit connecting the signal output of the sensing elements to the motor. The motor and cable system in conjunction with the control circuitry provide and drive the motor in stepping increments for continuously determining the liquid-vapor interface as referenced to the bottom of the storage tank. A remote digital display showing the quantitative values of the liquid-vapor interface level is provided. Scaling logic circuitry correlates the digital pulse counting technique in conjunction with a step-by-step movement of the probe assembly through the DC stepping motor.

摘要： A self-adjusting balance comprising a stirrup supporting a rotatable disk at its center. The front face of the disk is graduated in degrees from 0* to 90*, the graduations continuing on the reverse face from 90* to 0*. At the rim of the disk there are two slots, at diametrically opposite 0* marks, to accommodate cords, one to be connected to a weight to be measured and the other to a standard weight, the weight to be measured being connected to the cord in the front face 0* slot with the cord lying circumferentially against a portion of the rim of the disk to the point where this cord hangs free and vertical, the standard weight being connected to the cord in the diametrically opposite slot, this cord hanging free and vertical.
