Abstract: An onboard device for determining the weight of a vehicle. A transducer is coupled at one end with a fixed point on the vehicle and is coupled at the other end with a single or tandem axle of the vehicle. The transducer measures the change in distance between the fixed point and the axle and sends an electrical signal to a display unit. The display unit processes the signal and displays the vehicle weight which corresponds to the signal received from the transducer. An upper carriage mounts the upper end of the transducer to the fixed point on the vehicle. A lower carriage couples the lower end of the transducer with the axle. Telescoping pipes shield the transducer. A grade compensating device corrects the signal generated by the transducer to compensate for nonlevel surfaces.

Abstract: The present disclosure describes a housing module characterized in that it may be readily slid onto a counter-like unit which provides support therefor. The module finds particular application in the housing of electrical components, wherein the latter may be located either in a tray-like section disposed on the surface of the counter-like unit or in a box-like enclosure, below the unit. The components are electrically connected and communicate with one another via cables which are routed within the module and which may be pre-wired, thereby eliminating cable through-holes in the unit.

Abstract: Incorporated in a tensile member by which a hopper or the like is suspended from a ground-supported frame is an electronic load cell which is constructed and arranged to report to a convenient control location a signal which corresponds to the tension in tensile member as a measure of the weight of the material such as sand, crushed stone, cement or ore in the hopper. In order to prevent lightning which may strike the hopper or support frame from travelling along the tensile member and damaging or destroying the load cell, the tensile member is electrically isolated from both the hopper and the support frame by bushed connectors wherein the insulating bushing portion is stressed in compression. These bushed connectors simultaneously provide this electrical shock isolating function and both carry the static load and accommodate mechanical shock produced upon sudden changes in load, as when a load of stone is dumped into or dispensed from the hopper.

Abstract: A cooking apparatus includes a rotary table which is disposed inside a heating chamber such as to mount a food to be heated, and a motor which rotates the rotary table. The rotary table and the motor are integrally supported in a floating state by a resilient member, thereby allowing the food and the rotary table to vibrate or move vertically. This vertical vibration or movement is measured by employing a detector, and the weight of the food is measured from the output of the detector. The rotary table is provided with a biasing means interlocked with a door for regulating the height of the rotary table or stabilizing the same when the door is opened. In the case where the vibration of the rotary table is particularly detected, the rotary table is forced to vibrate by the action of the biasing means thereby allowing highly accurate measurement of the weight of the food.

Abstract: A load cell assembly having a predetermined overall stiffness and a mounting plate for reducing the apparent stiffness of the load cell assembly to that predetermined level are disclosed. A load cell is mounted on a base by a mounting plate so that the load cell is fixed with respect to mechanical ground yet is free to deflect under load. The overall stiffness of the assembly is reduced to a predetermined stiffness by selecting the resiliency of the mounting plate in accordance with the stiffness of the load cell. The resilience of the load cell may be determined by either undercutting the mounting plate or by proper selection of materials. An apparatus for protecting the scale from overloads and shock loads is also disclosed.

Abstract: An apparatus in a scale for protecting the load cell in a scale from overloads and shock loads is disclosed. A movable element has an inclined projection which projects under the load cell to limit the deflection under load.

When the weight is removed the appropriate clearance is automatically established. In one embodiment of the disclosed invention the load cell is provided with opposed elongated members and the movable element has a pair of inclined projections projecting under the elongated members to provide downstop protection and a second opposed pair of inclined projections projecting above the elongated elements to provide upstop protection. A load cell assembly having a predetermined overall stiffness and a mounting plate for reducing the apparent stiffness of the load cell to that predetermined level are also disclosed.
