Abstract: Methods, systems, apparatus, and articles of manufacture to control a vehicle based on signal blending are disclosed. An example apparatus disclosed herein includes programmable circuitry at least determine a first yaw rate signal based on first signal data output by a yaw rate sensor of a vehicle, determine a second yaw rate signal based on second signal data output by a steering wheel angle sensor of the vehicle, determine a blended yaw rate signal based on the first yaw rate signal and the second yaw rate signal, and adjust a torque to be applied by a motor of the vehicle based on the blended yaw rate signal.

Abstract: Improvements in the operation and maintenance of non-clogging pumps are provided which increase pump efficiencies through improved impeller design and vacuum assembly design, and which increase seal lubrication efficiencies through improved seal lubricant reservoir system design.

Abstract: A two-piece bearing housing is provided for use in centrifugal pumps having or requiring multiple chambers for enclosing or confining bearings or seals, and/or providing lubricant or coolant to the bearings and seals of the pump, the two-piece housing providing several improvements including the ability to make the two pieces from different materials, the reduction in scrap castings due to imprecision achieved in the casting process and improved structures in the housing for monitoring the lubricant chambers in the housing.

Abstract: A check valve of the flapper type structured for use in a self-primer pump is structured for attachment to the pump casing in a manner that facilitates servicing of the check valve, and includes securement means that are positioned external to the casing and a flapper that is located through an opening of the casing in a manner that enables the servicing of the valve without dropping the flapper or the hardware into the interior of the pump.

Abstract: A wear plate for use in a centrifugal pump is structured with at least one cutting element positioned at the inner bore of the wear plate, the cutting element or elements being positioned to impact the cutting edge of the vanes of an impeller and oriented in a direction relative to the rotation of the impeller so that the wear plate cutting element or elements can capture the solids in a processed fluid and hold them in place until the solids can be cut by the impeller vane or vanes, the wear plate cutting elements further being structured to be self-sharpening.

Abstract: A safety cover for the fill port of a self-primer pump is structured to improve the seal between the fill port cover and the fill port in the pump casing to thereby control the release of steam from the pump, and includes an improved sealing band between the fill port and fill port cover, an improved fill port cover design and an improved retaining clamp design.
