A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part. If applied to a finished polyethylene part, the irradiation and annealing must be accomplished with the polyethylene material not in contact with oxygen at a concentration greater than 1% oxygen volume by volume. When applied to a preform, such as a rod, the annealing of the bulk polymer part of the rod from which the finished part is made must take place on the rod before the implant is machined therefrom and exposed to oxygen.

A slip ring substantially prevents the connection electric wire from being twisted by rotational movement of the movable circuit board. A connection unit supports the slip ring and rotatably supports the top plate.

A pipe coupling clamp comprising a pair of clamp half members essentially C-shaped in cross-section each having a pipe flange receiving groove for receiving the mating flanges of two pipes to be coupled. The clamp half members being hinged together at one pair of ends by a hinge comprising plates and releasably connected together at the other pair of ends by a locking eyebolt and associated locking eyebolt nut hingedly connected at its proximal end to the end of one clamp half member to allow pivoting moving through a slot into an open securing jaw on the other end. The locking eyebolt comprises, at its proximal end, an eyebolt seating portion connected to a stepped threaded portion of reduced diameter at its distal end. Thus, initially, on loosening of the nut, the locking eyebolt will not disengage from within the securing jaw.

Forceps instrument comprising a sheath having a first end and an elongated maneuvering element slidably disposed in the first end of said sheath. The sheath has an axis. The instrument comprises two jaw-pieces, at least one of the jaw-pieces being movable away from and toward the other of the jaw-pieces when the maneuvering element slides axially in the first end of the sheath. The jaw-pieces have, in an extension of a part thereof, an arm extending progressively toward the axis of the sheath so as to form a first, internal, inclined surface extending progressively toward the axis and facing the latter and a second, external, inclined surface extending progressively toward the axis and facing the internal surface of the sheath. The arm has a convex excrescence which is slidable substantially against the internal surface of the sheath, the excrescence having a concave hollow cavity facing the axis. The sheath has, near its end beyond which the jaws extend, a transverse element against which the internal surface of the arm slides. The elongate maneuvering element terminates in a head housed in the concave hollow cavity so that, when the elongate maneuvering element is moved toward a free end of the sheath, it pushes the jaw-pieces back beyond the end of the sheath, thus causing the internal surface of the arm, which slides over the transverse element, to pivot by a ramp effect, moving the at least one jaw of the jaw-pieces away from the other jaw, the movement away being permitted by the inclination of the external surface which protrudes from the end of the internal surface of the sheath. The excrescence of the arm pivoting, during this movement, about the head while still being guided in the sheath, reverse movement of the maneuvering element causing the jaw-pieces to move closer by a reverse movement. The transverse element includes a passage having an axis substantially parallel to the axis of the sheath for accommodating an auxiliary tool between the two jaw-pieces.

A remotely activated reward dispenser. The remote dispenser delivers consumable rewards in response to a trigger signal from a remote triggering device. The reward dispenser uses a two stage delivery system to prevent unintentional release of the consumable reward. A vibration stage moves a portion of the consumable reward from a reservoir to a staging platform without crushing the consumable reward. The second stage transfers the consumable reward from the staging platform to an area accessible by the animal. A vibration damping system reduces the noise generated by the reward dispenser. An adjustable transition varies the feed rate for the consumable reward.
