Abstract: Hydraulic cylinders each comprising a hollow cylinder casing, a ram, and an annular seal are assembled automatically by a mechanism that stores and feeds seals, ram and casing members into separated axial alignment and then axially moves the components together until they are assembled. A tapered mandrel protects the inner surface of the seal from abrasion as it is fitted over the end of the ram, and a tubular insert with collapsing finges guides the ram and protects the seal from abrasion by the end of the casing as the ram is fitted into the casing. An automatic cap threading machine threads a cap in the open end of the casing after the push rod has been assembled in the casing. Retractable support means are provided for certain of the components in order to permit an assembly mechanism to fit over the components and move them along an axial path.

Abstract: A doctor bar consists of two different circular disks that are clamped or fixed in some other way on a cylindrical carrier bar. Circular disks having a smaller diameter and made from elastic material alternate with circular disks that have a larger diameter and are made of a very wear-resistant material, specifically ceramic. The difference in the outside diameter makes for one-half the groove of peripheral grooves of the doctor bar that are formed between the various circular disks.

Abstract: A method and apparatus for automatic orientation and assembly are provided. A first plurality of parts are mated with corresponding depressions or other irregularities formed in a pallet by vibrating the pallet and moving the parts thereover. A second plurality of parts are then oriented in a predetermined positional relationship with the first parts, for example matingly engaged therewith, by passing the parts over the pallet which is again vibrated, generally with different vibration parameters. The second parts may matingly engage corresponding irregularities in the first part, may be positioned and oriented by further irregularities on the pallet, or a template may be provided over the pallet with openings for positioning and orienting the second parts. The passing of parts over the pallel and vibration of the pallet may be repeated for additional parts to be assembled if desired.

Abstract: In a controlled deflection roll comprising a roll shell rotatable about a stationary support and braced or supported by support elements at the stationary support, a rotational moment is intentionally exerted at the opposite ends of the roll shell by force-exerting elements. These force-exerting elements extend in axial direction of the controlled deflection roll but are offset in spaced relation with respect to the lengthwise axis of the controlled deflection roll. These force-exerting elements operate in pairs in opposite directions with respect to one another. A lever arm is formed by the distance or spacing between the force-exerting elements and such lever arm exerts a greater rotational moment in the presence of modest space requirements and without deformation of the roll shell.

Abstract: A roll cover apparatus is disclosed for covering a roll of a papermaking machine. The apparatus includes a synthetic cover which is applied to the outer peripheral surface of the roll, which is of an electrically conductive material.

Abstract: An elongated insert has an enlarged central area with wrench faces formed thereon. On one side of the central area, an end of said insert is formed to provide a connector. On an opposite side of the central area, the insert is an elongated pipe having a series of annular barbs formed thereon. An inner split collar fits over and is dog locked to the pipe after it is slipped into the end of a hose. An outer locking collar fits over the split collar, compresses, and secures it in place. Various principles are shown for selecting a degree of locking forces which optimizes and matches the ease of installation vs. the grip that is required.

Abstract: An open ended, flat spiral belt is joined at its ends on a roll to form an endless cover. A spiral belt is fitted with a zipper assist in the seam area to facilitate the joining of the spiral belt on the roll. One part of the zipper assist is removably attached to one end of the spiral belt with the other part of the zipper assist being removably attached to the other end of the spiral belt. When the two sections of the zipper assist are zipped together, they pull the two ends of the spiral belt together, allowing for interdigitation of the spiral loops of the spiral belt, which then forms a channel for the introduction of a seam wire. Once the spiral belt is seamed on the roll, the zipper assist is removed and the roll is set in slow motion at about ten revolutions per minute. The entire fabric is subjected to application of heat from a hot air gun to set the spiral belt, now in the form of a spiral shrink sleeve.
