Abstract: A color recognition system which illuminates a test surface through the use of a source light and fiber optic cables. The light transmitted to the test surface is reflected into a light pipe and then transmitted through fiber optic cables to a first plurality of color filtered photo detectors. The photo detectors produce quantitative color component values for the tested surface. Light is also transmitted directly from the source light through fiber optic cables to a second plurality of color filtered photo detectors. The second plurality of photo detectors produce quantitative color component values for the light source. The values produced from the first plurality of photo detectors are then adjusted with respect to the values produced from the second plurality of photo detectors.

Abstract: A metal integral elevated post base for elevating the base of a wood post above a concrete base in which the post base is embedded. The post base includes a metal foot member embedded in the concrete base, a pair of metal post members integrally connected to the foot member partially embedded in and extending above the concrete base, and a pair of seat members integrally connected to the post members for supporting the wood post. Side members integrally connected to the seat members attach to the sides of the wood post. The post base is formed in two halves from a sheet metal blank and is configured as opposite halves and folded to form a single post and seat. Parts of the post base could be welded, but the preferred form is not welded.

Abstract: The floatable element or pad including a body of floatable material, such as for example a low density polyethylene, or a high density cross-linked polyethylene, and the like, having a horizontal cross-sectional shape, such as hexagonal, enabling a plurality of such floating elements or pads to engage in flat surface-to-surface contact thereby providing a substantially gapless floating insulating cover. In one embodiment, the floatable element or pad includes top and bottom layers, side walls, and a plurality of thru-posts extending between the top and bottom layers and providing structural rigidity thereto, and wherein the top and bottom layers, side walls and thru-posts cooperatively provided a plurality of dead air spaces providing additional insulation between the liquid, slurry, semi-liquid or the like on which an insulating floatable cover comprised of such floatable elements or pad is comprised.

Abstract: A lid for a deep frying pan consists of a side wall adapted to fit on to the side wall of the pan and a baffle wall and a second wall extending inwardly of the side wall; the baffle wall has a re-entrant neck portion extending towards the baffle wall and the walls define a chamber in the lid around the neck portion.An opening leading to the chamber surrounds the opening in the neck portion and an aperture in the baffle wall provides access to both the opening in the neck portion and to the chamber. Gases accumulated in the chamber flow across the opening in the neck portion to cut off the supply of air to the pan.

Abstract: This describes an automatic defect inspection system as could be applied to metallized masks or other patterns. The system causes each subfield to be individually aligned for inspection irrespective of the previous alignment of the pattern or any other sub-field. This is accomplished by scanning a preselected portion of each sub-field and adjusting the position of the scan based on the resulting signal while scanning a pre-established portion of the sub-field. In this way a portion of each sub-field is used as an alignment mark and stepping errors avoided.Once alignment is achieved a probe, comparable to the size of the minimum defect to be detected is scanned over the sub-field with an overlapping pattern to find defects such as excessive metal, metal in improper places or points where the metal is missing.

Abstract: A collar for fitting over the upper end of the cake discharge chute of a rotatable disc filter, or the like. The collar has a plurality of downwardly and inwardly sloping walls which substantially reduce any tendency for cake to stick to the sides of the chute. For use with heavy cake, reinforcing members may be provided for the collar. The collar is configured for use with discharge chutes of diverse design.

Abstract: A disc filter chute liner for being inserted in the passageway formed in a cake discharge chute of a disc filter and for being interposed between the cake discharge chute and cake passing therethrough and for preventing the cake from adhering to the cake discharge filter, the disc filter chute liner being provided with smooth and slick internal surfaces with respect to the cake whereby the cake passing through the liner will not adhere to the smooth and slick surfaces and thereby in turn will not adhere to the cake discharge chute.
