Abstract: Disclosed is an assembly for anchoring a submerged vehicle to a stationary object. The assembly includes a telescoping tube having a hollow inner tube and a hollow outer tube, each the inner tube and the outer tube having a proximal end and a distal end. The distal end of the inner tube slidably received within the outer tube through its proximal end. A snap button configured at the proximal end of the outer tube that can engage with a hole near the distal end of the inner tube for locking the movement of the inner tube within the outer tube. A rope having a first end and a second end, the first end of the rope attached to the inner tube near its proximal end. The second member passes through the eye of the spring hook and into the proximal end of the inner tube to form an anchoring loop. The second end of the rope exits the telescoping tube through the distal end of the outer tube and forms a boat hook loop.

Abstract: A drill bit, and associated method of manufacture, characterized by the presence of a low friction coating on the drill flute surfaces and the absence of such coating from the facets on the cutting surfaces of the drill bit. In one form, a tungsten carbide based microdrill bit is coated with a high temperature diamond like carbon to a layer thickness measured in microns. The cutting facets of the microdrill bit are then ground to expose the tungsten carbide material. The microdrill bit formed thereby is particularly useful in creating holes through multilayer printed circuit boards as a part of forming electrical vias. Low friction flute surface coated microdrills exhibit materially longer drill life, better drill location accuracy, can operate at materially greater chiploads, and produce higher quality holes through printed circuit boards.
