A device and system to hold cargo when rear vehicle seats do not lay flat to assist a person with storing and safely securing cargo. The device is made of a flat shelf to hold cargo, connected to a middle crosswise brace and longitudinal braces for support. A compartment area is created by the crosswise brace and longitudinal braces to store or hide small items. Using the device will protect the seats and give stability to the cargo.

A die assembly adapted to be attached to one of a wrench first arm and a wrench second arm. The die assembly includes a die having a pipe facing front spaced apart from but parallel to the pipe longitudinal axis, a wrench facing rear, and two spaced apart opposed sides, each connected to the die front and die rear. The die is thick on one side and thin on the other side so that the die facing front has a face that recedes from the pipe from one edge to the other edge so that contact between the die facing front varies depending upon the diameter of the pipe. The die rear also has a convex curve so that the die has a thick mid section.

A blasthole drill including a deck wrench for holding a drill pipe section to facilitate the unthreading of an adjoining drill pipe section from an overall drill pipe string. The deck wrench includes an engagement surface which is selectively engageable with an engagement surface of a drill pipe section to substantially prevent rotation of the drill pipe section in either direction about its longitudinal axis. The deck wrench is engageable with an upper drill pipe section so that a joint between the upper drill pipe section and a rotary head can be tightened when the rotary head is rotated in one direction. The deck wrench is engageable with a lower drill pipe section so that a joint between the lower drill pipe section and the upper drill pipe section can be broken when the rotary head is rotated in an opposite direction. The joint between the rotary head and the upper drill pipe section, once tightened, should be stronger than the joint between the upper drill pipe section and the lower drill pipe section. As a result, when the rotary head is rotated in order to break the joint between the upper drill pipe section and the lower drill pipe section, the joint between the rotary head and the upper drill pipe section will not break. The engagement between the deck wrench and the drill pipe is such that the drill pipe has a limited range of pivotal movement in either direction about its longitudinal axis to allow a certain amount of momentum to be transferred to the drill pipe by the rotation of the rotary head to enhance the tightening or loosening effect of the relevant joint.

A concealable surgical light device, such as for a birthing room, has a fixed housing and a single door for supporting the light on one side and decorative ceiling panels on the other side. The door is rotatably attached to the fixed housing. In a closed position of the door, the light is concealed within the ceiling structure, and the decorative panels are flush with the ceiling. In an open position, the light is deployable as it faces into the room. Rotation of the door between the two positions is powered by a motor acting through an actuator and a linkage system. The linkage system includes two first arms rotatably connected to an actuator rod and fixed to a pivot shaft such that extension and retraction of the rod pivot the shaft. Two second arms are fixed to opposite ends of the shaft and pivotally connect to two third arms, in turn connected to the door. Pivoting the shaft rotates the second arms which, in turn, move the third arms up or down to close or open the door.
