Abstract: A power transmission apparatus (10) including a base (13) with a driven shaft (11) rotably supported by the base (11) is disclosed. The apparatus (10) further includes an internal gear (17) surrounding the shaft (11) and fixed to the base (13), an arm (14) fixed to the shaft (11) and extending generally radially therefrom, a planetary gear (16) rotably attached to the arm (14) and meshingly engaged with the internal gear (17) so that rotation of said planetary gear (16) causes rotation of the shaft (11), and a connecting rod (19) rotably attached to an extension (20) fixed to the planetary gear (16) so that a means driving the connecting rod (19) causes rotation of the planetary gear (16), the connecting rod (19) being attached to the planetary gear (19) at a predetermined location from the planetary gear (16) by the length of the extension (20) and the connecting rod (19) angularly oscillating across a transverse axis of the shaft (11).

Abstract: A hose coupling through which extends a passage between two openings one of which is defined by a spigot and the other of which is defined by a sleeve, and wherein the spigot is of approximately the diameter of the spigot with the sleeve being adapted to receive a portion of hose to extend to the sleeve of an adjacent coupling so as to provide a sealing element joining two hose couplings which are attaching two hoses.

Abstract: A bicycle having a frame, a driven wheel rotatably supported on the frame, a drive sprocket rotatably mounted on the frame, a driven sprocket fixed to said wheel, a chain extending between the sprockets; a pair of levers pivotally attached to the frame, and a pair of links extending between the drive sprocket and levers, a pedal fixed to the extremity of each lever, and wherein said drive sprocket is rotated by the reciprocation of said pedals.
