Abstract: A balance-type scale is provided which is made nearly substantially entirely of plastic, thereby being resistant to environmental degradation. A counter-balance weight is of metal, but is embedded within the plastic. The scale is of two-part construction, comprising a body including the counter weight and a hook-like structure at the opposite end. A suspension member is pivotally connected to the body, and comprises a pair of spaced plates embracing the body. The suspension member includes a pointer, and the body is provided with indicia to be read opposite the pointer and readable directly in units of weight.

Abstract: An electronic scale used for weighing an object or material. The scale includes a weighing platform arranged to move upon receipt of a material thereon. The device further includes support means, a variable capacitor having a first and a second plate, spring means which is coupled both to the frame means and to the platform means such that movement of the platform means upon receipt of the material thereon causes the spring means to twist about an axis. The scale further includes counterbalancing means and energy absorbing connecting means to prevent error from being introduced into the weighing process, should vibrational moments be transmitted to the scale from its external environment. An alternative embodiment of the invention entails a flexure base scale, adapted to be used with counterbalancing means.

Abstract: Device for raising weights in precision balances, such as analytical balances, in which a number of weights from the smallest to the largest are disposed substantially in a single plane and are made associated with at least two pusher raising elements mobile in a direction substantially orthogonal to the plane of the weights, the pusher raising elements being raised by programmed operating means including rotatable annular disc members and cam means provided thereon. The disc members are rotated by acting on the weighing control members of the balance.

Abstract: A top loading precision balance having a weighing pan held horizontal by a parallelogram linkage is provided with a set of coaxial, annular weights mounted on the stem of the pan above the secondary or suspension pivot which connects the balance beam with a vertical pan carrier member of the linkage. The weights may be lifted from the stem of the pan in any desired combination by means of lifters operated by cams on a single control shaft, but remain coaxial in all positions, their common axis passing through the center of the pan and being laterally offset from the upright pan carrier, which is parallel to a stationary support member in the parallelogram linkage.

Abstract: A counterbalance weight addition or removal device for automatic use with a balance, a control circuit being provided to control the device, which device is arranged to deposit and lift from the balance, a plurality of counter weights in equal weight steps. The balance produces an electrical signal (load analog signal) proportional to the portion of a load on the balance not counterbalanced by counterweights. A digital indicator and four signal generators to receive said electrical signal, two of which signal generators are arranged to produce a signal for actuating the device, to deposit and lift a counterweight when said electrical signal exceeds the limits of a specified range, while the other two signal generators are arranged to produce a control signal when said electrical signal has exceeded the range of a signal equivalent to a counterweight step just completed, by more than the magnitude of that range. First and second delay members are provided whose delay times are longer than the oscillation time of the balance. The first delay member is permanently connected to the input side of the signal generators defining the said specified range, and the second delay member is arranged in the control circuit so as to be operable by the device at the end of each counter weight addition or removal operation to render said device inoperative for the duration of its delay time. The second delay member is also arranged to be rendered inoperative under the influence of a control signal from one of said other signal generators, to thus enable said device to then remain continuously operable.

Abstract: A platform balance including a housing, a weighing platform vertically movable relative to said housing, and at least one force indicating lever pivotally movable in accordance with the mass to be weighed by said balance, characterized in that the force indicating lever is pivotally supported in said housing beneath said platform at the upper end of a vertical support member the lower end of which is pivotally connected with the bottom wall of the housing, said force indicating lever being operable by the platform via load lever linkage means connected between the opposed side walls of the housing. In the illustrated embodiment, a pair of symmetrical force indicating levers are connected for pivotal movement in opposite directions to increase the sensitivity of measurement. Adjustable weight means are provided for varying the operating range of the balance, and tangent error is compensated for by appropriate selection of the dimensions and location of the center of gravity of the vertical support member.
