Abstract: A cargo bed cover is provided for enclosing the cargo bed of a vehicle. A generally planar outer frame is mounted to the cargo bed, and two generally planar inner frames are connected with hinges to the outer frame for pivoting relative to the outer frame. The inner frames are moveable between a position with the inner frame generally parallel to the outer frame and a position with the inner frame at an angle relative to the outer frame. A generally planar cover panel is connected with a hinge to each inner frame for pivoting relative to the inner frame between a position with the cover panel is generally parallel to the inner frame and a position with the cover panel is at an angle relative to the inner frame. Each cover panel is slidingly connected to the inner frame for sliding relative to the inner frame.

Abstract: An impact flowmeter utilizes a part cylindrical impact plate mounted by a parallelogram strain gauge from the top of a cylindrical housing with which it is coaxial. Material to be metered enters the flowmeter through an inclined inlet tube so as to impact the inner surface of the impact plate, and the horizontal reaction force from the plate is measured by the strain gauge. The flowmeter is simple to construct and can be made very compact, while the cylindrical surfaces of the principal components minimizes disturbances of the flow of material through the unit and thus provides good linearity.

Abstract: A weighbridge unit for use in a conveyor weigh scale has a support for part of the conveyor belt, such as a trough or one or more idlers, a bridge carrying the support, and load cells formed by cantilever strain gauge bridge units supporting the ends of the bridge, the electrical outputs of the bridge units being summed to provide a weighbridge output signal. Cantilever arms of the load cell bridge units preferably extend in the direction of movement of the belt.
