Abstract: A prolate spheroid shaped buoy is resiliently moored to an anchor by means of a cable wound on a reel in the anchor with the reel latched to power springs coaxially wound upon a shaft extending through the reel. The springs are pretensed on the shaft, prior to deployment, and the shaft is latched against rotation by a pair of spring biased pins engaging a plunger. The reel may thus rotate freely under control of a brake as the anchor falls from the buoy during deployment. The plunger is operated automatically when the anchor falls to the ocean bottom to release the pins in sequence with one pin engaging the cable reel before the other pin releases the shaft to ensure that the springs are latched to the buoy and cable to resiliently moor the same. A plate on the plunger arm closes the bottom wall of the anchor to prevent the ingress of contaminants.

Abstract: In a rotating drum type of digital clock, the minute drum is fixed to the drum shaft. A drive disc is carried on the shaft, freely rotatable thereon, adjacent to the minute drum. Sandwiched between them is a detent ring which is keyed to the drive disc, but which has limited axial freedom with respect to both the disc and the drum, being pressed toward the web of the drum by a spring. Convex detent bosses extending axially from the ring can engage with any of a plurality of recesses in the web of the minute drum. The drive disc is advanced each minute by the normal actuating mechanism, and drives the minute drum through the detent ring. A setting knob is engageable with the shaft, permitting rotation of the latter, and hence of the minute drum, for setting purposes. In setting, the bosses are forced out of the recesses, the ring retracting axially, so that the drum can be rotated with respect to the ring.
