Abstract: Bottle filling machines are known in which a centering bell is attached to a bushing for vertical movement up and down on a filler tube. Downward movement of the bushing and bell is limited by a shoulder on an enlarged tip portion of the filler tube. The area of contact between the bushing and shoulder in prior art arrangements is a narrow circular flat area perpendicular to the long axis of the filter tube. Repeated contact between the bushing and the shoulder on the tube tip causes wear on the bushing and on the shoulder. The present invention reduces the rate of wear of the contact areas by forming the shoulder so that it slopes downwardly and outwardly an an angle of about 20.degree. to 45.degree. with respect to a vertical axis. The region of the bushing which engages the shoulder is also sloped downwardly and outwardly at substantially the same angle.

Abstract: Disclosed is a proportioning valve which is of simple design compared to prior art arrangements and is easily constructed. The valve comprises lower and upper body members, the lower body member having a chamber region closed off by a flexible diaphragm of elastomeric material or, in an alternative arrangement, two diaphragms. The bottom of the chamber region has first and second inlets and the wall of the chamber has at least one outlet. Two cam followers are secured above the diaphragm, for axial movement only, in alignment with the inlets and they co-operate with a face cam which is movable both axially and rotationally. Rotation of the face cam results in one cam follower moving up, while the other moves down, thus resulting in movement of one portion of the diaphragm towards its associated inlet while the other moves away from its associated inlet, thereby controlling the relative rates of flow of liquid into the chamber region from the inlets.

Abstract: A clamp which comprises a metal band adapted to be wrapped around a pipe over a suitable gasket. The longitudinal edges of the band are secured to lug bars, one having fingers secured to it and the other having threaded bolts secured to it. The free ends of the bolts are each provided with a nut and washer soldered together to form a nut/washer combination. Each finger is generally U-shaped including a base portion and two leg portions. The bottom edges of the legs adjacent their free ends are welded to a lug bar. The legs converge over a part of their length from a first spacing in the region of the base portion sufficient to accommodate a nut/washer to a second spacing in the region of the lug bar sufficient to accommodate a bolt but not a nut/washer. The top edges of the converging parts of the legs slope outwardly with respect to the bottom edges. The legs have flat ends to accommodate a nut/washer and tabs adjacent the top edges restrain the nut/washer against outward movement while the nut is tightened.

Abstract: There is a requirement when using toilets to prevent and/or remove the accumulation of odor-causing substances from the sidewall of the toilet bowl. This can easily be accomplished with ceramic toilets where the water is directed to swirl around by angled holes formed in the flushing rim. However, in stainless steel toilets, the material is too thin to form angled holes and the water has previously simply entered a flushing rim and run vertically down the wall of the toilet. This invention is an improvement in the flushing rim portion of a stainless steel toilet which causes the water to swirl around as in ceramic toilets, to effectively clean the inside of the toilet bowl. Instead of drilled holes, the rim has upturned notches in its lower wall which cause the flushing water to spray the toilet bowl wall in an overlapping pattern. The notches also contribute to the swirling action of the water.
