Abstract: A driveshaft for driving agricultural machinery has two profiled tubes which are movable one inside the other and serve to transmit torque. Two protective tubes (5, 6) are provided which are also axially movable one inside the other. To be able to lubricate the profiled tubes, a maintenance aperture is provided which, at a certain driveshaft length, is obtained as a result of the overlapping position of two apertures (11, 12) in the protective tubes (5, 6). However, when not used, the aperture (11) in the outer protective tube (6) is covered by a closing sleeve (9). When extending the driveshaft after moving the closing sleeve (9), for the purpose of providing access to the apertures, the closing sleeve (9) is automatically returned into the closed position by a cam (13). This design measure results in a higher degree of safety by ensuring that the apertures are always closed when the driveshaft is in operation.

Title: Optical fiber system and method for overcoming the effects of polarization gain anisotropy in a fiber amplifier
Inventor: GILES CLINTON RANDY
IPC: H04B10/17
Filed: 1995-01-20
Granted: 2000-04-04
Abstract: An optical fiber system and method is disclosed that overcomes the effects of polarization gain anisotropy in rare-earth doped optical fiber amplifiers. An optical fiber has at least one rare-earth doped fiber portion for amplifying a light signal. Light signals are passed through the doped fiber portion in a first incident polarized state.      This light signal is reflected back from a Faraday effect mirror and through the doped fiber portion in its orthogonal polarized state so as to overcome the effects of polarization gain anisotropy. The rare-earth doped amplifier is preferably an erbium-doped fiber amplifier. A signal is initially passed through one part of a Faraday optical circulator and out a second port into the doped amplifier. On its return pass, the light signal enters the second port and then exits a third port. The optical amplifier can include a wavelength division multiplexor coupler for merging the pump signal with the original light signal. Various amplifier configurations are also disclosed which are either co-propagating or counter-propagating and reflect only the signal, reflect only the pump signal, or reflect both the pump signal and original light signal.

Abstract: Suture dispensers for retaining armed sutures are disclosed. A dispenser for sutures is disclosed that includes a first and second rigid and substantially flat panel, each comprising a central opening and an edge. A needle park is disposed adjacent the central opening of one of the first and second panels. The panel edges cooperate to retain the first panel against the second panel to form a dispenser of substantially two dimensional character. The disclosed dispensers are thin and thus require less storage and shipping space. Methods of loading dispensers are also disclosed. By winding the suture material in a flat spiral around a set of winding pins between the two panels, the disclosed dispensers can be easily and accurately filled, yet the resulting coiled suture can be withdrawn via the central openings without twisting or kinking the suture material.
