Abstract: An improved grain mill is presented herein comprising a dispenser adapted to receive and store a material, and a grinding mill adapted to receive the material from the dispenser. The grinding mill comprises a grinding cylinder and a motor assembly adapted to rotate the grinding cylinder. When the material is dispensed into the grinding mill from the dispenser, and the motor assembly is engaged, thereby causing the grinding cylinder to rotate, the material is moved along a tapered passage and forced across a sharp edge, causing the material to be ground, crushed, broken, flattened, or cut, dispensing the material into a material receiving portion and thereby allowing the material to be delivered to the user.

Abstract: An actuation pressure control system effects actuation of adjustable seal segments between stationary and rotating turbomachinery members. At least one actuator is coupled with each of the adjustable seal segments and controls a position of the seal segments, respectively. A pressure system is disposed within the turbomachinery that measures or estimates ambient pressure representing an actuator back pressure acting against the actuator. A pressure regulator via a controller pressurizes the actuator to a level sufficient for a desired seal operation and controls actuator pressure based on the actuator back pressure.

Abstract: A composition for producing surface layers on wood or other substrates is formed from diatomite, expanded perlite, chopped glass fibers and a thermosettable resin mixed in specified amounts to provide a flowable mixture. When applied to the substrate as a layer about 1 to 2 cms. thick and the resin component has cured, a tough, impact-resistant, watertight surface is created on the substrate. The new compositions and surfacing methods are particuarly useful for refinishing the hulls of wooden boats.
