Abstract: This invention deals with a permanent hose fitting for use with reinforced hose including a flexible inner tube, a wire reinforcement which surrounds the inner tube and an outer cover, the hose being comprised primarily of rubber or rubber-like material. The fitting is of the steel socket and insert type wherein an annular recess is provided for receipt of the hose with cover thereon. Projections on the inner surface of the socket are of a configuration to pierce the cover upon crimping or swaging of the socket, to contact the reinforcement and to be deformed thereby into gripping engagement. Controlled bending of the shape-biased projections provides a device for accommodation of size and material differences and allows for compromise in fitting design for different sizes or styles of hose.

Abstract: A crimping machine has a rockable hydraulic cylinder which in a force transmitting position drives a die segment assembly into a tapered cavity to force the assembly to contract radially for crimping the socket of a fitting onto the end of a hose. The die segment assembly is a unitary chain of linked die segments which may be fed into and removed from the die cavity in a serial manner to avoid obstructions. A floating die separator with axial projections engages angular surfaces on the bottom of the die segments to position the segments prior to crimping in a circular array which is equally circumferentially and radially outwardly spaced.

Abstract: A means for ensuring a firm seal between a hose fitting and a hose comprising a sealant that also acts as a lubricant and is applied to the nipple portion of the fitting prior to insertion into the core tube of the hose. The sealant causes the core tube or the core tube liner, if used, to soften and swell, thereby completely filling and firmly engaging the threads in the nipple portion, and also causes a localized plasticized condition in the core tube or liner adjacent the threaded portion of the nipple resulting in the core tube retaining firm engagement with the nipple during temperature cycling and flexing of the hose assembly.

Abstract: Electromechanical impact meter enables obtaining real-time on-site collection rate information concerning undersea mining of manganese nodules or other solid minerals at a remote location.

Abstract: A hand operated swager for attaching a fitting to a hose includes a housing having a turning means rotatably mounted at the top portion thereof and a die for radially contracting the fitting onto the hose is removably mounted at the lower portion of the housing. The turning means is fixed against axial movement on the housing, is manually rotatable by the use of a wrench, and includes a ball nut threadably engaged with a pusher assembly that is axially but not rotatably movable relative to the housing whereby rotation of the turning means causes the pusher assembly to move axially into engagement with the fitting but imparts no rotary force to the pusher assembly that might be transmitted to the fitting. The swager also includes spring retainers for removably retaining the die in the housing.
