Abstract: A scale is disclosed for weighing moving loads. The scale includes a weighing platform having entrance and exit ends. The platform is connected to a tipping member mounted to pivot about a fulcrum. A weighing device is operatively connected to the fulcrum. Downward movement of the platform entrance end causes the tipping member to pivot in a first direction and downward movement of the platform exit end causes the tipping member to pivot in a second direction. First and second stops limit movement of the tipping member in the first and second directions, respectively. As a load enters the platform, the tipping member pivots against the first stop such that the weight is distributed between the fulcrum and the stop. As the load approaches the center of the platform, the tipping member pivots off of the first stop such that the weight is measurable by the weighing device.

Abstract: In a top scale balance which has a Roberval's chain 10 and a load weight transmitting lever 30 and in which a movable post 13 of the Roberval's chain 10 is connected to a point of force 32 of the lever 30 through an elastic connection fulcrum 51, a horizontal member 12 nearer to the elastic connection fulcrum 51, out of upper and lower horizontal members 11, 12 of the Roberval's chain 10, is greater in rigidity than the other horizontal member 11. Alternately, the upper and lower horizontal members 11, 12 are equal in rigidity and the elastic connection fulcrum 51 is positioned, in the vertical direction, at the center between the upper and lower horizontal members 11, 12. Such an arrangement prevents or reduces the movement of the elastic connection fulcrum 51 in the back-and-forth direction due to an offset placed load. Thus, even though the top scale balance is made in a compact and thin design with the lever ratio increased, the top scale balance is high in precision with a less offset position error.

Abstract: A load to be measured is transmitted to a load cell, such as a compression load cell, through a double piston, single cylinder load transmitter that has a pressure chamber between two pistons in the single cylinder. One piston bears against the load. The other piston bears against the load cell to form a floating link between the load and the load cell when a sufficient pressure is introduced into said pressure chamber to prevent unwanted, off-center load application force components from adversely affecting any measured results. Preferably, at least one axially outwardly facing end surface of the piston bearing against the load cell has a curved end surface area. A rocker pin with a pressure controllable variable length may be formed by making both axially outwardly facing end surfaces curved. Several load transmitters may be arranged in parallel to transmit larger loads into a load cell.

Abstract: A center-lock portable truck scale has an end positioning post (4) between sides at ends of a truck scale and a central positioning post (8) positioned centrally in truck-scale sections. Positioning rods (5 and 9), preferably bolts, form positioning bumpers at adjustable distances from the lock posts. Hinges (23, 29 and 49) are employed to connect sides of the scale bridge (11, 12) so that large truck scale decks may be foldable for easy transportation to the site of installation. Scale loading weight is carried on a vertical load-cell pillar (75) that rests pivotally on a load button (77) that is positional in a load-button indentation in a top surface of strain-gauge beams (80). The central positioning post and positioning bolts prevent excessive end-to-end movement while the end positioning posts prevent excessive side-to-side or twisting movement of a scale unit, thereby positioning scale weight directly on load cells (3) in jarring and temperature-change use-conditions for more accurate weighing.

Abstract: A weighing apparatus employing dual load cells or dual load cell sets is provided with a hinged weigh frame attachment to transmit only vertical load to one load cell or set of load cells and prevent transmission of moments about the longitudinal axis. A ball and dual cup arrangement is connected between the weigh frame and the other load cell or set of load cells to transmit vertical load but prevent the transmission of moments about either the longitudinal or transverse axes of the load cell. Because of the decoupling arrangements, the weighing apparatus requires only longitudinal shift adjustment for only the load cell(s) connected to the hinge.

Abstract: An electronic balance incorporating a Roberval mechanism has a weighing pan attached to a vertically elongated arm connected to one end of a beam such that the arm remains vertically oriented as the beam swings around its supporting point in the middle.

Abstract: Apparatus for weighing vehicles in motion includes a base to be anchored to a roadbed below ground level in the path of moving vehicles and a pair of scale platforms mounted on the base for receiving the wheels on the opposite sides of the moving vehicles. Load cells are provided between the base and the platform for producing signals indicating the load applied by each wheel on the platform. A pair of flexure struts is connected between each platform and the base to apply a preload and permit relative movement therebetween in the vertical direction and to resist relative movement in the horizontal direction. The flexure struts extend lengthwise in the direction of traffic flow and are resistant to loads in that direction while being flexible in the vertical direction to permit application of the preload and flexing of the load cells. The dynamic weight signals from the load cells are converted to digital form and operated on to provide information as to the weights of the passing vehicles.

Abstract: Load cells incorporating rocker pin configured columnar central structures within a weighing system have the attribute of self-erecting upon being displaced from a vertical orientation due to dynamic transverse loading effects, as may be occasioned by vehicle movements onto a scale. The resultant transient vector forces thus developed have been observed to cause a rotational phenomenon in the rocker pin configured cells which causes unacceptable damage to the instrumentation control communication components of the load cell system. A mounting technique for such load cells is developed wherein only these rotation inducing forces are restrained, while the vertical force vectors representing valid load data are maintained in an unrestricted or uncompromised manner. In one aspect of the invention, a hexagonal form of mounting between a rocker pin neck-contact surface region and a corresponding receiver cavity achieves a fully pivoting and freely abutting geometry while effecting the noted restriction of rotation.
