Abstract: A shower drain adapter system configured to allow use of a bondable waterproof membrane with a shower pan drain system comprises a drain body and an integrated bonding flange extending upwardly from the drain body. The integrated bonding flange is operable to be sealably attached to a bondable waterproof membrane to provide a substantially waterproof seal between the membrane and the adapter. A lower mating flange is separable from the drain body, the lower mating flange operable to mate with a component of a shower pan drain system installable on a waste pipe. The lower mating flange includes a substantially rigid frame; and a pliable gasket disposed at least partially about the frame, the pliable gasket having an inner diameter sized to correspond to an outer diameter of a portion of the drain body.

Abstract: A segmented drain system comprises a drain body, operable to mate with a drain fitting installed in a bath or shower area, and a bonding flange body, adjustable relative to the drain body. An integrated bonding flange extends from the bonding flange body, the integrated bonding flange being operable to be sealably attached to a bondable waterproof membrane to provide a substantially water-tight seal between the membrane and the bonding flange body. A seal is oriented between the integrated bonding flange body and the drain body, the seal being operable to provide a slidable, substantially water-tight interface between the integrated bonding flange body and the drain body.

Abstract: A friction brake for a louvered structure having a plurality of slats pivotally interconnected between opposed stiles of a rectangular frame is described. The friction brake is a flat arm having a pair of spaced apertures. One of the apertures is dimensioned to receive a cylindrical sleeve of a connector which is secured to a pivot rod of a slat and the other aperture is dimensioned for friction fit about the cylindrical sleeve connected to the pivot rod of an adjacent slat whereby to arrest the connector and all the slats. All of the slats are interconnected together by a longitudinal slat interconnecting member which is pivotally connected to all of the slat connectors whereby when any slat is positioned to a desired slat angle all of the other slats will move in unison to that desired angle and be retained thereat by the friction retention of the second aperture of the friction brake about the cylindrical sleeve of one of the slats. Two or more friction brakes can be mounted in a stile.

Abstract: A slat tensioning mechanism is provided for holding interconnected slats of a louver assembly in a desired angulated position. The slat tensioning mechanism comprises a housing having wheel positioning means for rotationally receiving a bearing wheel. The bearing wheel has an outer circumferential flat wall, and hub means adapted for securement to an end connector of a slat, whereby the bearing wheel and the slat rotate together. A tensioning arm assembly is pivotedly engaged to the housing and has an arm disposed at a predetermined location with respect to the outer circumferential flat wall of the bearing wheel. The arm has a friction surface at a free end thereof for applying a pressure on the outer circumferential flat wall of the bearing wheel for frictionally arresting the bearing wheel at the desired position. The slat tensioning mechanism is adapted to be disposed in an upright of the louver assembly.

Abstract: A louver assembly is comprised of two or more louvers, each of the louvers having pivot connections at opposed ends thereof, with the pivot connections pivotally securing the louvers between opposed stiles of a shutter frame for pivoting motion of the louvers in the frame. Each louver has a connector secured to a common longitudinal side edge thereof. Each connector has a cavity with a connector rod extending thereacross and extending co-extensively to the longitudinal axis of its associated louver. Each connector rod has at least one engageable rib on an outer surface thereof. A control rod is provided with two or more transverse connecting arms each having a connecting end recess. Each end recess has a plurality of indentations formed at a predetermined location in a curved clamping inner face thereof for receiving the rib of a respective connector rod captive therein by clamping pressure of the connecting arms about the connector rod to angulate the louvers at a desired angle.

Abstract: A shutter assembly which is comprised of a support frame formed by opposed parallel hollow side frame members and a bottom and top block member interconnected between the ends of the side frame members. A plurality of equidistantly spaced slats are pivotally inter-connected to one another and disposed between the side frame members in a parallel relationship. The side frame members each have a removably securable inner side wall which is provided with equidistantly spaced holes to receive opposed pivot pins of each of the slats. A slat positioning mechanism is disposed in one of the side frame members and has a pair of vertically disposed slat interconnecting bars. Pivot pin connectors are secured to each of the pivot pins and each has a pair of connecting arms pivotally connected to respective one of the slat interconnecting bars. A control gear, of circular disc shape, has gear teeth on at least an outer peripheral portion thereof.

Abstract: A shutter frame member is comprised of an elongated plastic extruded body element having opposed parallel longitudinal side edges in which is formed a connector for removable connection thereto of an elongated edge adaptor. The connecting cavity is provided with a plurality of elongated connecting channels on opposed side surfaces thereof. The edge adaptor is provided with a flange which has ribs for selective engagement with the channels provided in the elongated edge cavity of the body whereby to provide an adjustment of the width of the shutter frame member.

Abstract: Bone fusion dental implant of the type able to form an artificial dental root as a support for a fixed prosthesis composed of one or more dental crowns, said implant being inserted into the bone of the upper or lower jaw by drilling a hole at a suitable location and to which implant the surrounding bone tissue fuses permanently as it grows, said implant also having a substantially cylindrical shape, with a crown end (3) provided with means (11, 4) for connecting with a prosthetic reconstruction and an apical end (2) designed for insertion into the bone, said implant having an externally threaded section (6) extending from crown end (3) over no more than one-third of the entire length of the implant, and a s section (1) without an external thread extending from apical end (2) over no less than twothirds of said length. In the section (1) not threaded externally, the implant is coated with a bioactive material, preferably hydroxyapatite, and is surface-threaded to make it rough and/or porous.
