Abstract: A method and apparatus for remotely opening a manual valve of a gas cylinder from a remote location. The gas cylinder is first connected to a purge system which is purged of oxygen and pressurized with an inert gas to a pressure near that of the gas cylinder. The manual valve is then engaged with a pneumatic stepper mechanism. Pneumatic fluid is supplied to the pneumatic stepper mechanism to rotate the manual valve a predetermined stepped increment. The step of supplying pneumatic fluid to the pneumatic stepper mechanism is repeated, after pausing to let the system settle, to rotate the manual valve another stepped increment. The steps of rotating and pausing are repeated until the manual valve is opened. The purge system is then vented to atmosphere through a diffuser. Both the pneumatic stepper mechanism and the purge system are fully operable from the remote location. The pneumatic stepper mechanism includes a ratchet assembly and an attachment assembly connecting the ratchet assembly to the manual valve.

Abstract: A fly-fishing reel has a rotatable spool provided with a click gear engaged by a pivoted pawl which can apply resistance to rotation of the spool in opposite directions by independently adjustable spring means. A pair of exteriorly exposed adjustment knobs are each provided with an eccentric pin extending into the reel housing to slide a plate which carries a pretensioned spring engaged with one of the opposite radial sides of the pawl. By rotating the knobs, the slides move linearly to vary the contact point of the springs with the pawl and thereby regulate the moment arm of the force resisting rotation of the pawl and thus the click gear and spool to which is engaged. Since the adjustments are independent, the resistances to rotation of the spool may be varied as to degree and to which direction of rotation they apply. The slides mount the springs in a manner to limit the degree to which the springs may follow movements of the pawls.

Clicks can be generated as desired when the rotor rotates in the forward or reverse direction. When the rotor rotates in the reverse direction, the click pawl is caused by the brake lever to engage the click gear to produce clicks and simultaneously resist the reverse rotation of the rotor.

Abstract: A lashing device for securing objects on ship's decks. The lashing device comprises a U-shaped frame member having two legs and an attachment part. Between the frame member legs extend a strap winding-on drum and a spring-biased shaft, and a holding pawl member is attached on the shaft portion that projects laterally beyond one of the frame member legs. The pawl member engages with a cogged ratchet wheel on the winding-on drum and prevents the strap from being unwound from the latter.The shaft is movable in a direction coinciding with the rotational direction of the winding-on drum. Owing to this arrangement the holding pawl member is pressed out of its engaged holding position upon actuation of said shaft, preferably effected by impact thereon by means of a ratchet wrench, and when the holding pawl is thus in its disengaged position the strap may be unwound from the drum through the action of the tension in said strap.

Abstract: A locking finger member (7) cooperates with notches (3, 4) of a parking wheel (1). The respective contact surfaces (3a, 6a and 3b, 6b) are inclined in an asymmetric manner with respect to a radius of the parking wheel (1). It is then possible to choose these inclinations in such manner that the torques exerted on the locking finger member (7) upon its disengagement under the action of the rotation of the parking wheel (1) are substantially equal, even for a small longitudinal dimension of the locking finger member (7). Thus it is possible to construct a locking device of very small overall size.
