  • Publication number: 20230204406
    Abstract: A cast load cell comprising a load sensing portion integrally cast with a first mounting portion. The load sensing portion has a flexure portion spaced apart from the first mounting portion by a flexure gap. The load sensing portion has at least one sensor cavity above at least a portion of the flexure gap. A second mounting portion is integrally cast with the load sensing portion above the flexure gap. A load sensor is connected to the load sensor portion and positioned within the sensor cavity above a portion of the flexure gap. The first mounting portion, the load sensing portion, and the second mounting portion define an integral, low-profile, weld-free, substantially homogenous unitary cast member.

  • Patent number: 9726535
    Abstract: Embodiments of the present disclosure are directed to load cell assemblies configured for measuring loads or weight associated with a semi-trailer. In one embodiment, a load cell assembly includes a shear plate load cell configured to be coupled between a frame and a support member of the semi-trailer. The shear plate load cell detects or measures the trailer's weight with a sensor positioned on a strain sensing section of a plate. The strain sensing section is positioned at a location offset from the plate's centerline. The shear plate load cell is accordingly configured to provide an ideal moment balance that allows accurate load measurements independent of where the load is applied relative to the load cell or the support member.

  • Patent number: 7561034
    Abstract: A load warning system for use with a vehicle having a load-support portion, a frame, and a vehicle-support portion movably coupled to the frame. The system has an engagement portion mountable to the vehicle-support portion or the frame and is movable therewith as a unit. A load indicator is mountable to the other one of the vehicle-support portion or the frame, and is spaced apart from the engagement portion when in a first position. The load indicator moves to a second position and engages the engagement portion when the frame moves a selected distance in response to the load applied to the load-support portion. The load indicator provides a signal upon being moved to the second position. A warning indicator is coupled to the load indicator and provides an improper load warning to a user in response to the signal from the load indicator.

  • Patent number: 7506538
    Abstract: One aspect of the invention is directed to a suspension and weigh system for use with a vehicle having weight bearing members. The system has a support connectable to the weight bearing members of the vehicle. The support has a length and a neutral axis along at least a portion of the length. A weigh system is coupled to the support and configured to measure and/or determine weight carried by the weight bearing members. The weigh system has a load sensor attached to the support and positioned substantially adjacent to the neutral axis. A data processor is coupled to the load sensor and configured to receive the output signal from the load sensor for determining the weight carried by the axles. In one embodiment, a display is coupled to the data processor and configured to display data related to the weight carried by the axles.

  • Patent number: 6733809
    Abstract: The method for applying dry toppings to baked goods includes the steps of pre-treating a surface of the baked goods, after baking, with an adhesive substance such as a pregelatinized wheat starch suspended in a solution and thereafter applying the dry toppings to the treated surface. Such an application has been shown to decrease wastage of such items as sesame seed topping from as much as 50% to as little as 5%.

  • Patent number: 6422800
    Abstract: The system is for use in a front loader assembly for refuse vehicles, which include two spaced fork members which are secured to a cross-member, which in turn are supported by lift arms which move the load supported on the forks into the refuse truck. The system includes flexure beams which are formed by cutout portions in a sensing portion of each fork. The flexure beams are located symmetrically about a centerline of a sensing section of each fork, and alternate between two different lengths, with the flexure beams of each length being in alignment. Three sets of long cutout portions and 3 sets of short cutout portions are included, in addition to a central pair of cutout portions on which the strain gauges are mounted. The sensing section of the fork is configured to provide the necessary stiffness with the plurality of flexure beams therein.
