Abstract: A deformable feeding membrane for an apparatus that pneumatically conveys solid or semi-solid materials, e.g., gravel or crushed rock. The deformable feeding membrane includes a tubular portion adjacent an inlet feed auger. The sidewalls of the tubular portion includes sidewalls that are outwardly deformable, so that gravel or rocks that might otherwise become pinched or stuck between an inner sidewall of the feeding membrane tube and a flyte of a screw auger can pass through the membrane tube, with sufficient space provided by the deflection of the feeding membrane tube wall. In an embodiment, the tubular portion may be provided sufficiently elastic so that the flexible tubular sidewall may be operably displaced a distance delta (?), wherein the distance delta (?) may be at least as large as the thickness of the sidewalls of the tubular portion.

Abstract: An imager includes an array of pixel sensors. Each pixel sensor indicates at least two different primary color components of an image. For each pixel sensor, at least two storage locations are located in the array and store the indications from the pixel sensor.

Abstract: An apparatus for pneumatically conveying granular material such as gravel. The apparatus includes a vehicle base mounting plate, a prime mover such as a diesel engine, a hydraulically driven air blower, a hopper for receiving gravel to be conveyed, and a hydraulically driven auger assembly for moving gravel from the hopper to a pneumatic pick-up point. After pneumatic pickup, the gravel is transported through an extended network of suitable pneumatic tubing such as low friction, thick wall, PVC pipe sections, to a desired discharge location, where the material is discharged into a catch can for downward placement at a desired point. In a preferred embodiment, the auger assembly comprises a three piece unit, with a shaft, an inner auger section, and an outer auger section. The outer auger section is a replaceable wear part which can be repaired, rebuilt, or replaced as necessary due to frictional wear on the auger due to contact with the solid being conveyed.
