Abstract: A cleaning blade system for a variety of electrophotographic apparatuses. A preferably reversible, elongated, elastic wiper blade is longitudinally supported by a relatively rigid, elongated holder. The wiper holder is universally adaptable to a variety of differently configured cleaning blade mounts by a plurality of mounting adapters which all have a uniform interface with the wiper holders so that all wipers and wiper holders can be uniform. Each mounting adapter has a second interface for fastening it to at least one of the varied cleaning blade mounts in the same way that a conventional cleaning blade is fastened to said one. The holder and mounting adapters include provisions for locating and stabilizing the disposition of wipers relative to the drums. Preferably the holder includes an interlock securing a wiper blade without adhesives. The wiper blade may include flared edges to enhance contact pressure against the drum and extend its useful life.

Abstract: Two substrate leaves are coupled by a folded flexible circuit medium. Integrated circuit components can be mounted to opposite faces of both leaves. A signal terminal projects from one of the leaves. Both leaves include paths for communicating signals between their respective components and the terminal. Preferably the leaves are formed by two outer, rigid substrates each laminarly affixed to a respcective inner substrate, the inner substrates being separate sections of the folded circuit medium and the outer substrates being separated sections of a rigid circuit medium. Components are mounted to the exposed faces of the substrates. The fold includes paths for communicating signals between the leaf distal from the terminal and the terminal, the signal paths between one leaf and the terminal being closely matched in length and impedance to corresponding paths between the other leaf and the terminal.

Abstract: A conduit network on a bristle face of a brush communicates with a supply of cleansing or rinsing effluent under pressure, and dispenses the effluent generally uniformly over a wide area of the bristle face through distributed outlet holes. A preferred quick connector couples the network to the effluent supply. A valve controls the rate of flow into the network. Control of brush movement during washing and grooming is facilitated by: an adjustable strap securing a user's hand to a top control face, a finger wall projecting from the control face including finger stops, a palm heel catch, liquid drain-off channels which also knurl the control face for better gripping, and a preferred length allowing a user's fingertips to overlap the front of the brush.

Abstract: A roller skating device combining advantages of conventional roller and in-line skates, and skateboards is presented. A “boot” (as defined herein) for snugly encasing a selected foot of a user has an undercarriage, i.e. a frame, connected to it in fixed relation. A rigid member having a planar top is affixed to the undercarriage, preferably behind the heel of the boot, for engaging the free foot of the user, i.e., the foot not wearing this invention. A plurality of rollers, connected to the undercarriage, rollingly support the undercarriage, and all connected to it, on a skatable surface. The free foot engages the planar top by resting on and, at selected times, pressing forcefully against the planar top to help control the device during operation. Two exemplary embodiments are described herein: an embodiment having a rectangular pattern of rollers and an embodiment having a single line of rollers.

Abstract: A display banner that may be attached to headgear and adjusted to provide weather protection for the back of the head, neck, ears and portions of the back and shoulders. It may allow the top of the wearer's head and hairstyle to remain uncovered, well ventilated and well groomed. Its shape and insertable supports enhance its inherent potential area for displaying promotional material and/or the preferred art of the wearer.
