Abstract: A dead bolt lock system including a slider member operatively coupled to a dead bolt such that when the slider member is in a first position, the dead bolt is in an extended position. When the slider member is in a second position, the dead bolt is in the retracted position. The system also includes a first movable member positioned in a path of movement of the slider member and configured to be displaced by the slider member to allow the slider member to move to the second position. The system includes a first lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member, a second lock having a first condition preventing the displacement of the first movable member and a second condition allowing the displacement of the first movable member.

Abstract: Apparatus for sampling the fluid contents of a container comprising an elongate tube open at one end and having at its other end a cap provided with an air passage. Extending through the tube is an operating rod having a stopper at one end and a valve between its ends. A handle connected to the rod is operable to move the rod between positions in which the opposite ends of the tube are sealed by the stopper and the valve, respectively.

Abstract: A reversing thermometer frame adapted to be clamped to a water sampler and lowered to a predetermined depth in a body of water. The frame has a base coupled to a case containing one or more of the reversing thermometers. The thermometer case is rotatable through about 180.degree. and is biased by a torsion spring reacting between the case and the biase for rotation from a first position to a second position. A releasable latch reacts between the base and the case to latch the latter in its first position against the bias of the spring. The thermometer case is open at one end for the insertion and removal of thermometers. At the open end of the case is a closure that is linearly and rotatably movable relative to the case so as selectively to close and open the open end of the case. The connection between the case and the closure is such that the latter must move linearly a predetermined distance relative to the case before it can be rotated, thereby preventing inadvertent loss of the thermometers.

Abstract: A Kemmerer style water sampler has a tubular body open at both ends and through which extends a connecting rod. The lower end of the connecting rod is fixed to a closure for the lower end of the body. The upper end of the connecting rod is releasably latched to an upper closure and carries a latch member which is engageable by and disengageable from a pair of clasp members mounted on the upper closure for movements in directions into and out of latching position. Each clasp member is provided with an upstanding motion transmitting member having inclined, confronting surfaces spaced apart to provide a chamber. Reciprocably accommodated in the chamber is an operating member that is tapered complementally to the inclination of the surfaces of the motion transmitting members so that movement of the operating member axially in one direction effects movement of the clasp members out of latching engagement with the latch member, thereby enabling the upper and lower closures to seal the opposite ends of the body.
