Abstract: An apparatus is described for burn-in and/or functional testing of microelectronic circuits of unsingulated wafers. A large number of power, ground, and signal connections can be made to a large number of contacts on a wafer. The apparatus has a cartridge that allows for fanning-in of electric paths. A distribution board has a plurality of interfaces that are strategically positioned to provide a dense configuration. The interfaces are connected through flexible attachments to an array of first connector modules. Each one of the first connector modules can be independently connected to a respective one of a plurality of second connector modules, thereby reducing stresses on a frame of the apparatus. Further features include for example a piston that allows for tight control of forces exerted by terminals onto contacts of a wafer.

Abstract: A cord storage device is provided which allows the simultaneous winding and unwinding of both halves of a cord while maintaining both cord ends in position for use and the device also permits unwinding of the cord from the storage device while one cord end is held in a fixed position.

Abstract: An automatic disconnecting device is provided for hoses containing pressurized gas or liquids. The disconnecting device is activated upon user application of excessive lateral tension to the hose resulting in lateral displacement of the automatic disconnecting device resulting in release of the hose coupling release ring which secures the hose to the supply nipple.

Abstract: A hand tool is provided having opposing jaws with teeth and depressions mounted on one of said jaws to enable torque to be applied to a variety of sizes of fasteners. A wedge portion and a hexagonal hole portion of the tool provide added functions of a screw driver and pry bar and grip for a hexagonal socket.

Abstract: A laminated structural panel which is especially well suited for the construction of a bulkhead used to partition a trailer or other cargo container. The center of the panel is formed by a polyurethane foam core panel sandwiched between a pair of flexible plastic reinforcing sheets adhesively bonded to opposite sides of the core panel. Additional layers of foam are adhesively bonded to the reinforcing sheets, and the outer foam layers are covered by puncture and abrasion resistant skins which are adhesively bonded to the foam. The reinforcing sheets provide the structural foam with tensile strength and with both beam and column strength because of their ability to resist being stretched. The outer foam layers provide impact resistance and enhanced strength due to the effect of the added laminations.

Abstract: A device which unloads materials from a vehicle cargo area such as the bed of a pickup truck. A pair of mounting brackets are bolted to opposite sides of the vehicle bed. Pivoted to the brackets are the front ends of rigid frame arms which carry a rotatable drum between their back ends. A flexible conveyor sheet is wound on the drum and can be unwound onto the vehicle bed to receive materials loaded therein. A motor driven or manually operated drive system rotates the drum to unload the cargo as the conveyor sheet is wound up on the drum. The pivotal mounting of the frame arms permits them to be raised with the tailgate of the vehicle to a storage position during transport of the load.

Abstract: An improved high pressure coupler disconnecting device providing increased force necessary for uncoupling high pressure lines under high pressure at a predetermined point of separation. A flexible high pressure hose attached to the female portion of the coupler is placed through a tower device which surroundably restrains movement of the flexible hose. The tower base, supported by a ring, is positioned in such a manner as to apply lifting force to the female coupler lock sleeve when the tower is moved from the neutral position. The annular construction permits the invention to function in any position around a full 360.degree. sweep from the centrally located release mechanism.
