Abstract: A hydrophone deployment apparatus is provided for an underwater vehicle, rein the apparatus includes an annular drum releasably mounted about the tail portion of the vehicle. A plurality of arms are pivotally connected to the aft portion of the drum and are capable of swinging from forward positions flush with the vehicle to aft positions behind the drum. A device is provided for enabling retention and selective releasing of the arms from the forward flush positions. A hydrophone is releasably mounted on the inside of one of the arms, and a cable is connected between the hydrophone and the vehicle with an intermediate portion wound on the drum. With this arrangement a release of the arms during travel of the vehicle will cause the drum to be released and the vehicle will swim away from the drum pulling the cable until it is completely off the drum, at which time the hydrophone is pulled from its mounting in the arm. At this time the drum is jettisoned and the hydrophone becomes operational.

In other embodiments, the hinge pin has resilient flap-like members which normally extend outwardly of the shank of the hinge pin, and which are resiliently present against the hinge pin during insertion of the hinge. The flap-like members flapping outwardly after passing through the hinge to secure the hinge pin in place. In other embodiments, first and second members, which extend into the hinge pin opening of a hinge from opening ends thereof, are interconnected by a spring member which extends outwardly of the hinge to retain the hinge pin in place.

Abstract: A rotary kiln having a live ring is supported by a pair of rollers on shafts. The ends of each shaft are supported by bearings carried at the ends of a weigh beam having a rocking bearing so that the rollers can tilt to follow changes in the slope of the kiln. To allow the rollers to follow any axial movement of the live ring, upon thermal expansion or contraction of the kiln, the rocking bearing is slidable on a partly cylindrical segment.

The major parts of the assembly include a spigot having a base arranged to be rigidly secured to the vehicle part and a tubular projection extending from the base. The projection includes an outer end defining a first annular surface facing axially outwardly of the projection. A tubular cap is provided having on its inner end a second annular surface and engageable in abutting relation with the first annular surface of the projection. A centering and aligning means is located at the inner end of the cap to ensure registry of the first and second annular surfaces.

Abstract: A clamping device for releasably snap joining or clamping two panels comprises a plug element and a bush element. The plug element comprises: a stem portion engageable with the walls of a hole in a panel; a body portion; a head portion formed with legs that can be resiliently moved near one another and defined by at least one longitudinal slit; a notch extended from the longitudinal slit within the body; and a slider slidable between the legs to lock the latter at widened out position.

Abstract: A slack adjuster assembly for coupling a brake shaft to a power actuator comprising a bushing member fixed to the brake shaft and having an annular flange therearound and having an annular bearing surface next to the flange which carries a series of teeth on a shoulder facing toward the bearing surface, a lever having a hub member journaled on the bearing surface and having a toothed shoulder interengaging with the teeth on the flange when the hub member is moved toward the shoulder, a spring urging the hub member toward the flange to keep the teeth normally engaged, and a pawl carried in one of said members and having lugs engageable with teeth of the opposite member to separate the teeth by compressing the spring and to advance the engagement of the teeth in a direction determined by the direction of rotation of the pawl.

Abstract: A demountable hinge is disclosed for mounting a door to a frame. The hinge is particularly suitable for cabinets such as kitchen cabinets and includes a first section, and a second section pivotally attached to the first section to provide rotative hinge action. The first section includes a generally rectangular tab portion which has a button-like projection upstanding from one side and is dimensioned to be received by a correspondingly configured receiver strap securable by screws to the frame. The receiver strap is constructed of resilient material and includes an aperture which is dimensioned and located to receive the button-like projection in resilient snapped engagement to retain the first section on the frame. The second section may either be adjustably fastened directly to the door by screws of the like, or it may be demountably attached to the door in a manner similar to that used to mount the first section to a frame.

Abstract: The apparatus includes a first connecting link having a pair of axially opposing ends with one of the ends being coupled through a uniball to a drive portion of an actuator. A second connecting link includes a pair of axially opposing ends. One of the ends of the second connecting link is coupled to a driven portion, e.g., a butterfly valve. Coupling means, including a mating plug and socket, is provided for adjustably coupling the remaining opposing ends of the first and second links. The mating plug includes four sides and one hole disposed eccentrically therethrough and parallel to the sides. The remaining end of the second link includes a socket for mating with the plug. The plug can be mated in eight different rotational positions with respect to the socket. At each of the eight different rotational positions, the eccentric hole is disposed in a position which determines one of a predetermined number of available couplings between the first and second links.
