Abstract: A valve assembly for use in an inner tube member of a core barrel head assembly positionable within a drill string of a drilling apparatus. The valve assembly works using two separate surfaces and a biasing element with a force. When hydrostatic pressure is present forces are created on these surfaces, these forces have a direct relationship with pressure, as an increase in pressure will increase the force and vice versa. The surface areas are designed such that the valve will maintain closed while under a predetermined fluid pressure, indicating to the driller that the inner tube has landed. When the driller relieves the fluid pressure and the pressure decreases, the force difference between the respective forces decreases until the valve opens for drilling through the force from the biasing element.

Abstract: A yard hydrant locking collar has two C-shaped steel hardened plates connected together at one end by a rivet. The rivet acts like a hinge and allows the top and bottom plates to swivel open and closed. The other end of each top and bottom plates has a locking hole. A one inch tapered slot is cut into the top plate near the locking hole. The top and bottom plates are rotated so the collar fits around the hydrant pipe. The locking holes and slot are positioned near the hydrant locking hole and the collar locking holes are aligned. A padlock is opened and tilted away from the pipe and the free arm of the padlock is placed through the locking hole of the hydrant handle and positioned over the locking holes of the collar. The padlock is then tilted back towards the pipe. The tapered slot allows the padlock to move towards the pipe so that the free end of the padlock can move through the locking holes. Once the free end of the padlock passes through the collar locking holes, the padlock can be raised and locked.
