A collar and method are provided for coupling a casing with an applicator. The collar comprising: a body having a first end, a second end and an external surface extending therebetween; a bore extending through the body, the bore having an upper bore portion adjacent the first end for releasable engagement with the attachment portion of the applicator, and a lower bore portion adjacent the second end for securing to the casing; an internal partition extending radially into the body between the upper bore portion from the lower bore portion, and a sealing ridge connected to the partition adjacent the upper bore portion, the sealing ridge adapted to contact the attachment portion of the applicator to form a seal.

A withdrawal system (1) for a container (2) and comprises an immersion pipe (4) mounted on and projecting into the container (2) as well as a withdrawal head (5) that is attachable to the immersion pipe (4) by means of a rotary connection. The withdrawal head (5) attached to the immersion pipe (4) is secured by means of a mechanical locking unit.

A quick coupling fitting (1) is described, comprising a first connector (2) and a second connector (3) coaxially screwed along a longitudinal axis (L), said first connector (2) comprises at least one guide track (27) which is integral with an external casing (23), a sliding ring (28) slidably mounted axially aligned with the external casing (23) and adapted to slide on said at least one guide track (27), a screwing ring (29) screwed with said external casing (23), said sliding ring (28) comprises at least one tooth (288), said second connector (3) comprises a locking ring (38) rotatably mounted axially aligned with said external body (3) which comprises at least one housing (388), said at least one tooth (288) being mountable with said at least one housing (388) in a fully screwed position of the quick coupling fitting (1).

This disclosure relates generally to couplings used in mining and other applications. An extraction device for removing an adapter from a port formed in a structure is provided. The extraction device may include an end wall and a side wall. The end wall may define an external face of the extraction device. The side wall may extend axially away from a periphery of the end wall. The side wall may terminate at an end face of the extraction device. The end face may have a larger dimension than the port so as to abut the structure adjacent to a periphery of the port. The side wall may include an inner surface and an outer surface. The inner surface may have a threaded portion.

An anti-rotation device for preventing a hydraulic connector assembly from leaking. Various embodiments of the anti-rotation device provide a mechanism whereby threadably engaged connectors, such as compression fittings, are permitted to rotate only a fraction of a turn after loosening. For many applications, the limited degree of loosening is sufficient to prevent the onset of leaking. Structurally, the anti-rotation device can include a band that is secured to a female nut of a hydraulic connector. Protrusions extend laterally from the band and engage with a stop tab on the male body of the hydraulic connector assembly, thereby limiting rotation of the female nut that would otherwise cause leaks. Locking provided by zip tie structures proximate the free ends of the anti-rotation device.

A pipe connection and a method for sealingly connecting pipes which, in their opposite end portions, are provided with removable rings arranged in grooves provided in the peripheries of the pipes, the pipe connection being provided with a first nut, which is provided with an internally threaded portion and is arranged to encircle the end portion of the first pipe and has a shoulder portion which may abut in an axially supporting manner against said ring, and a second nut, which is provided with an externally threaded portion and is arranged to encircle the end portion of the second pipe and abut with a shoulder portion in an axially supporting manner against said ring, and the nuts are in threaded engagement with each other and are arranged to press radial pipe-end faces of the pipes against an axially supporting portion of a seal and pipe carrier.

A tamper evident assembly is provided for an associated fluid fitting that has a threaded nut that cooperates with a threaded body. The tamper evident assembly includes a collar having a through opening dimensioned for receipt over at least one of the nut and body. A holding mechanism is operatively associated with the collar for movement between (i) a first position that extends radially inward a dimension no less than the through opening, and (ii) a second position extending radially inward that prevents axial removal of the collar over both of the nut and body of the associated fluid fitting.

A tubular hose stem with a flange, a first left hand threaded section on the outer surface of the stem generally adjacent the flange, a first JIC/swivel nut over the flange having an inner diameter smaller than the outer diameter of the flange, a second lock nut threadably engaged to the hose stem on a second left threaded section adjacent the JIC nut, a conical washer fixedly secured around the hose stem between the first and second threaded sections, an O-ring positioned adjacent the washer opposite the left side of the washer; and a ferrule having a first end fixedly threaded to the hose stem and having a second end larger in diameter than the stem. The lock nut may have knurled surfaces and the inner diameter of the ferrule and outer diameter of the stem may have circumferential raised ribs to engage hosing.

A block for a fluid conveyance device (e.g. a hydraulic pump or motor) has a spindle mountable on an outlet face of a housing of the device. The spindle has a spindle fluid conduit in fluid communication with a housing outlet on the outlet face of the housing. A barrel is mounted on the spindle, the barrel having a barrel fluid conduit in fluid communication with the spindle fluid conduit. The barrel fluid conduit has a fluid outlet port oriented at an angle in a range of about 10-170 with respect to direction of fluid flow from the housing into the spindle fluid conduit. The barrel may be mounted on the spindle in a plurality of configurations, the fluid outlet port pointing in a different direction in each configuration of the barrel. The block provides the ability to direct hoses to a desired location while reducing the likelihood of failure of any given fitting on the device.
