摘要： A disclosed diver fin includes a blade and a foot pocket, distinct from one another and releasably connected to one another by one or more rails extending from a leading edge of the blade to the foot pocket. The rails extend from either side of the foot pocket and extend parallel to one another at least partway along the length of the blade towards a trailing edge of the blade. Each rail includes two sections: a first rail section, extending from the leading edge of the blade and terminating in a free end, and a second rail section, extending from the foot pocket and terminating in a free end. The free end of one rail section includes a female recess, and the free end of the other rail section terminates in a male extension, slidably receivable in the female recess. The disclosed fin is reconfigurable to accommodate different diving conditions.

摘要： Disclosed is an adaptor for connecting a grease injection gun to either of a lipped or a threaded grease cartridge; the adaptor including a tubular sleeve, having an internal diameter slightly larger than the external diameter of the grease cartridge, but smaller than the lip of the lipped cartridge, for receiving the discharge end portion of the cartridge; and an adaptor head shaped and dimensioned to form a closure over the tubular sleeve, the adaptor head including an outer face configured to releasably connect with the grease injection gun, and an inner face shaped and configured to releasably connect with the tubular sleeve and the cartridge, with a flow passage extending between the outer face and the inner face, for fluid communication between the grease injection gun and the cartridge.

摘要： This disclosure provides an overshot loader mechanism for transporting material in an overhead trajectory from a filling to a discharge position. The overshot loader mechanism includes at least one control arm, pivotally connected at one end to a chassis frame, and at the other end to a thrust end of the load arm, and a bucket pivotally connected to a load end of the load arm. Rotation of the control arm about its pivotal connection moves the thrust end of the load arm from a terminal high point, where the load end of the load arm is located towards the bottom of its trajectory for bucket filling, to a terminal low point, where the load end of the load arm is located towards the height of its trajectory. This configuration reduces the centre of gravity of the loader mechanism, while retaining sufficient bucket height to clear the vehicle's operator cab.

摘要： An apparatus for the relief of grease under pressure in the delivery line of grease guns and similar pressure delivery devices includes a 3-port valve in which the relief port is located between the delivery and inlet ports and includes a one way flow control valve mounted therein. The one way flow control valve is maintained in a closed position by the pressure of the grease and is activated to be opened to reduce the pressure in the valve body and allow the grease to return to the grease reservoir.

摘要： An air chuck for facilitating the connection of a pneumatic hose with a threaded stem of a tire valve includes a housing with an air passage. The housing includes an air inlet port connectable to the pneumatic hose, and an air outlet passage to receive the threaded stem of the tire valve. A clamping member is mounted externally about the outlet passage and includes a hollow tubular member, a front end portion of which terminates in a plurality of separate, radially deflectable fingers, a free end portion of each finger extending towards the discharge end of the outlet passage. The free end portions of each finger define an aperture for receiving the threaded stem of the tire valve. The size of the aperture is variable by the movement of a sleeve, slidable over the body of the housing and the clamping member.

摘要： The invention provides an apparatus comprising a grease gun (10) having a delivery line (22), the apparatus being configured to return grease under pressure from within the delivery line (22) of the grease gun (10) back to a grease reservoir (14); the grease gun (10) comprising a dispensing head (12) fitted to reservoir (14) containing grease and including a grease inlet port (16), for receiving grease from the grease reservoir (14), a grease outlet port (20) connectable to the delivery line (22) for dispensing grease; a pressure chamber (18) wherein the grease inlet port (16) is in fluid communication with the grease outlet port (20) via the pressure chamber (18); a piston (28) operable for displacing the grease from the grease inlet port (16) to the grease outlet port (20); and a one-way flow control valve located between the pressure chamber and the grease outlet port to inhibit the reverse flow of the grease from the grease outlet port back into the pressure chamber; the dispensing head (12) further comprising a pressure return port (26), located upstream of the grease inlet port (16) and linked to the grease outlet port (20) by a pressure return passage and openable into the pressure chamber (18), for returning the grease under pressure to the pressure chamber (18) and the grease reservoir (14), in which the piston (28) acts as a valve movable between a first position where the pressure return port (26) is closed and a second position where the pressure return port (26) is open.
