The weighing apparatus comprises a base (1) and a receiving platform (2) for the load to be weighed, parallel to said base, a test body (3) extending between the base (1) and the platform (2), the opposite ends (3a, 3b) of which are fixed rigidly to the base (1) and to the platform (2) respectively, one (3c) of the faces of the test body (3) comprising strain gauges associated with an electric circuit. The test body (3), molded in one single piece with the base (1) and the platform (2), is reces...

A multipurpose scale construction, particularly for household kitchen use, comprises a base, a compressible spring mounted thereon, a platform on the spring and at least one container for holding material to be weighed. The container may be inverted over the platform and spring and secured to the base protecting the scales when not in use.

The sounds of the alarm are produced by a membrane exposed to the atmosphere and against which strikes a vibrating blade located in a recess provided in the outer surface of a piece which constitutes a section of an envelope tightly surrounding the watch movement, the latter being located in a recess provided in the inner surface of said piece.

A multiple lever balance having a main lever supported on a main knife edge, a load input knife edge supported on the main lever, a lever having a load to be weighed applied thereto, a horizontally disposed weighing plate connected with the load input knife edge, and a force member connected with the weighing lever and in rolling contact with the weighing plate to assure that horizontal forces are applied vertically to the load input knife edge.

An apparatus for automatically weighing out material in desired weight quantities by roughly weighing a portion, gauging it for its weight relation to the desired quantity and adding or subtracting material if necessary to achieve the desired quantity.

The piece count calculating method and apparatus operates to determine the number of pieces in a container or the number of pieces to be placed into a container by employing known values primarily provided by a weighing system to automatically calculate a desired unknown value. The basic weight values are converted to pulse signals and digital calculator techniques are utilized to accomplish the calculation with the ultimate result being expressed in whole numbers.

A frame composed of two side bars and of two screws acting as wristlet lugs clamps the case between the bars. The appearance of the watch can be varied by changing the position of the case within the frame, by substituting a different case or different frame parts, or by any combination of these ways.

An overload protective arrangement for strain gauge type load cells used in weigh scale force measurement. Calibrated springs are interposed in the tension coupling between the load cell and the weigh scale load resolving lever to provide an inextensible link in the coupling until the designed load limit of the scale is reached and as a progressively extensible link when the scale load limit is exceeded. Another embodiment uses a piston moving in a fluid pressure cylinder as part of such couplin...

There is provided a railroad car dumping apparatus including an invertible cradle, a weighable platform assembly invertible therewith, weight-sensing means coacting between the cradle and the platform assembly in compression only, and stop means operable to support the platform assembly when the cradle is in its inverted position without a railroad car. This structure overcomes weight inaccuracies introduced by submitting the weight-sensing devices to both tensile and compressive forces and simp...

A truck chassis frame is provided with means for supporting a truck body thereabove, which means is utilized for operating a mechanism connected to a scale for weighing the body of the truck and the contents thereof. Before the truck operates in transit, the operator puts into operation means for fixing the truck body with respect to the chassis frame to prevent any movement of the truck body relative to the chassis frame during transit.
