Abstract: Systems and methods for measuring displacements at the picometer level are provided. A system can include a Michelson interferometer having a fixed arm and a measurement arm. As the length of the measurement arm changes, the output supplied to the interferometer from a variable wavelength light source is changed until the intensity of the resulting inference pattern is maximized. The wavelength of the light at the point the interference pattern is maximized is then measured by mixing light from the light source with the output from a frequency comb generator. The resulting frequency measurement is then converted to a length measurement.

Abstract: The present invention relates to a polymeric cove base support for installation where flooring meets a wall, comprising extruded straight portions and molded exterior corner and end portions. The cove base support comprises an upper wall portion, a lower toe portion and an intermediate curved or concave cove. The wall portion is substantially perpendicular to the toe portion. The curved cove comprises an outer cove surface for facing the wall-floor interface and a spaced apart inner curved cove surface facing the room when installed. The spacing between the two curved coves for the straight portion creates an open area, where the open area includes a supporting or reinforcing bar juxtaposed between the curves, preferably positioned perpendicular between the two curve coves in the center region of the open area, and extending the length of the cove base.

Abstract: A side rail for installation in a shredder and method of fabrication in which the side rail has fingers that are partially embedded in a base. The fingers are made from steel and the base is made from cast aluminum. The fingers have a dovetail shape at an outer end thereof that is immersed in molten aluminum in a mold. When the aluminum is allowed to harden the fingers are embedded in the base. The side rails are much lighter weight than previous side rails, and are still sufficiently strong to be used in a mobile shredder.

Abstract: A mobile shredder has a shredder mounted in a truck box in combination with a vibratory hopper. The vibratory hopper is open on one side and opens into a fixed hopper. The fixed hopper is mounted on the shredder and is shaped to direct material to be shredded into the shredder. The vibratory hopper and the fixed hopper are located immediately adjacent to one another, but slightly apart from one another, so that vibration of the vibratory hopper does not cause vibration of the fixed hopper.

Abstract: A method for fabricating molded parts utilizing a plurality of mold details having respective molding surfaces defining respective contours. The method selecting a first group of the mold details and disposing the selected mold details adjacent to one another in a first predetermined spatial relationship so that the molding surfaces of the selected mold details are contiguous, to define a first molding cavity for producing a first desired molded part. A hardenable polymeric material is injected into the molding cavity and hardened to form the desired molded part. Various combinations of mold details can be assembled to produce multiple parts in a common mold frame.
