Abstract: A portable stair lift system, for assistance in traversing short or medium length stairways, employs a pair of spaced elongated solid metal plates extending the stairway length and supported by a pair of vertically extending end brackets attached to a block of wood at each end thereof. An axle extends through each pair of end brackets and each axle supports a roller transversely disposed at the metal plate ends. At least one of these rollers is provided with a sprocket wheel secured to the axle between split roller segments. A reversible drive gear motor, drive chain connected to the sprocket wheel, drives the roller. A heavy duty conveyor belt is positioned about the pair of rollers. A passenger support system (either a chair seat or step segments) is secured to and movable with the conveyor belt. Manual switch means for controlling motor operation and direction are provided and actuatable by the passenger at any point along the stairway.

Abstract: A fish scaling apparatus and process is disclosed wherein a vertical stand 11 supports a pair of elongated, concentrically spaced, perforated drums 20,22 (FIGS. 1-7). An access door 23 is provided along the length of the outer drum 20 to permit loading and unloading of a quantity of fish in the space d between the two drums. Drums 20,22 are provided, respectively, with a plurality of dimpled perforations 25,26 through the sidewall thereof with each perforation having rough edges facing toward the space between the drums (FIG. 3a). A perforate water pipe 13 serves as an axle about which the drums 20,22 rotate and an electric motor 40, in conjunction with a selection of pulleys, (FIGS. 1-2), chain and sprocket wheels (FIG. 5), and/or gears (FIG. 10), supply the rotative force for the drums. Drums 20,22 are designed to rotate together (FIGS. 1-7), separately (FIGS. 8-9), or in opposite directions (FIG. 10).
