Abstract: An improved joint assembly has a boot seal with a retainer ring. The retainer ring is effective to hold the seal in place on a housing having a circular side surface with any one diameter in a range of diameters. The retainer ring includes an annular base having a plurality of interspersed groups of radially inwardly extending fingers or tabs. Each group of fingers includes fingers of different lengths to cooperate with housing side surfaces having different diameters within the range of diameters. Thus, each group of fingers includes a medium length finger which cooperates with a housing side surface having a diameter that falls within a middle portion of the range of diameters. Each group of fingers also includes a relatively short finger which cooperates with a housing side surface having a diameter which is greater than the mid-range diameter.

Abstract: In an arrangement for fastening a structural part (1) to a round steel chain by means of two webs (3,6) which overlap the long sides (19,20) of a chain link (9) and bridge the gap between said long sides (19,20) a centering member (5) is used which centering member is provided with a bore (12) and parallel side faces (10,11) having a spacing from one another which is approximately equal to the width of the gap between the long sides (19,20) of the chain link (9) partially overlapped by the webs (3,6). At least one web (3) being provided with a guide (4) which holds the centering member (5) in a prescribed position.

Abstract: A controlled deflection roll comprising a stationary roll support and a roll shell rotatable about the roll support. The roll shell is guided in radial direction upon the roll support in order to perform displacement movements, typically lift movements. The controlled deflection roll is equipped with a shutoff element, a slide or a valve, which upon exceeding a given displacement magnitude of the roll shell causes outflow of pressurized fluid medium from a pressure line, and thus, prevents the development of the full pressing or contact force which otherwise could lead to destruction or damage of the roll shell. In an overflow line, branching-off of the pressure line, there can be arranged a residual pressure regulator equipped with valve means or throttle means for preventing drop of the pressure in the pressure line below a desired value.

Abstract: A cabinet which contains an appliance such as a refrigerator is provided with novel hinges having one member secured to the body of the appliance and the other member adapted to carry both the door of the appliance and the door of the cabinet for simultaneous operation. The hinge members are interconnected in a known manner by means of connecting links pivotally mounted at each end to the respective member. A spring may be incorporated in each hinge for biassing the doors into the closed position.

Abstract: The disclosure concerns a roller for use in pressure treatment of webs of material, or the like. The roller includes an annular roller shell and a beam support extending through the roller shell. The pressure on the roller shell is transmitted through a supporting element to the support within the shell. The supporting element includes a sleeve that is received in a recess in the support. The sleeve is connected with a source of pressurized liquid through a conduit in the support. The sleeve opens toward the shell. A spring normally urges the sleeve toward the shell. The sleeve is closed in the space between the support and the shell except where it opens toward the shell. The inner diameter of the section of the sleeve closer to the shell is approximately the same as the outer diameter of the sleeve more remote from the shell for improving the hydrodynamic force exerted by the "plug" of pressurized liquid inside the shell.

Abstract: A locking device for coupling an externally splined power take-off shaft with an internally splined coupling hub which may be part of a universal joint shaft of an agricultural implement, including locking elements which are radially movable between an inner locking position and an outer unlocking position, the elements being engaged in the locking position with a circumferential groove in the power take-off shaft. A retaining member is axially slideable on the coupling hub to a position to engage the locking elements to hold them in their radially inward locking position. Insertion of the power take-off shaft into the coupling hub causes an actuator device which includes radially movable members extending into the bore of the coupling hub to be moved radially outwardly by engagement with the power take-off shaft thereby to engage the retainer member to urge the retainer member toward its position holding the locking elements in the radially inward locking position.

Abstract: An apparatus for coupling tubular frame members is disclosed. A coupling block has a plurality of couplings extended therefrom. Each coupling has a guide recess, a clamp mounted for sliding movement within each guide recess, a bolt having a first end connected with the clamp and a second end screwed into the coupling. The clamp is provided with a hole which receives the first end of the bolt. A bearing within the hole supports the bolt at the first end for free turning movement. The bolt has a circular groove adjacent the first end, and a pin is mounted to the clamp and extended through said circular groove. The clamp is operable to slide responsive to the rotation of the bolt within the guide recess to press the tubular frame member surrounding said clamp and the coupling defining the respective guide recess thereby solidly holding said coupling and tubular frame member to each other.

Abstract: A disposable bag is supported from two rectangular wire formed loops defining a stand which extend transversely to one another in a pivotal C-like relation. The invention provides for two horizontally disposed elements which cooperatively support a bag and stand cover when it is in an upright position. Also provided are rolling means for facilitating the transport of the stand, and an integral handle unit to enhance maneuverability. A removable shelf, to support the bottom of the shelf is also disclosed.

Abstract: The end of a wire strand adjacent to a hot metal or resin type end fitting is relubricated after application of the fitting to the strand by injecting lubricant through a thin tube extending between the wires of the strand in the hot metal or resin portion of the fitting from the surface of the hot metal or resin to the neck of the fitting.

The connector includes a coupler having a pair of sockets. One of the sockets having a bearing seat adapted for receiving and confining a pivot-like ball therein and the other socket adapted for receiving and capturing an end of the rod-like member. The coupler is slotted for permitting enlargement of the sockets to enable insertion of the end of the rod-like member into one of the sockets and insertion of the ball-like member into the bearing seat of the other socket. The connector further includes a sleeve adapted to be received over one end of the coupler in an initial position and rotatable relative thereto to a final position.

Abstract: A clamp-down device whereby an inaccessible portion, such as the rear end of an equipment rack, for example, may be secured to a base or anchor member from the front end of the rack which is readily accessible. The clamping arrangement includes a clamping bar having a wedge-shaped end which fits into a complementarily wedge-shaped slot in a pin secured to the base and extending through the rear end of the equipment rack. A jack-screw is operatively connected between the equipment rack and the clamping bar adjacent the front or accessible end of the rack, so that by turning the jack-screw, the wedge-shaped end of the clamping bar is forced tightly into the wedge-shaped slot in the pin to thereby draw the rear portion of the rack tightly against the base.
