Abstract: A method, system and apparatus for testing an integrated circuit chip. The system including: means for forming a liquid polyalphaolefine layer on a bottom surface of the integrated circuit chip, a top surface of the integrated circuit chip having and a bottom surface not having signal and power pads; means for placing a surface of a heat sink into physical contact with the bottom surface of the polyalphaolefine layer; means for electrically coupling the integrated circuit chip to a tester; means for electrically testing the integrated circuit chip; means for electrically de-coupling the integrated circuit chip from the tester; means for removing the heat sink from contact with the polyalphaolefine layer, all or a portion of the polyalphaolefine layer remaining on the bottom surface of the integrated circuit chip; and means for removing the polyalphaolefine layer from the bottom surface of the integrated circuit chip.

Abstract: According to the present invention, a method of controlling the burning in of at least one I/C device in a burn in tool is provided. For high power device, the tool has a heat sink positioned to contact each device being burned in, and has a socket for mounting each device to be burned in, and a power source to supply electrical current to burn in each device. The method includes the steps of continuously monitoring at least one process parameter selected from the group of current, voltage, power and temperature, and varying the voltage to maintain at least one of the parameters at or below a given value. Also, a technique for burning in low power devices without a heat sink is provided. The invention also contemplates a tool for performing the above method.

Abstract: An improved method for removing and collecting plating wax from waxed components such as turbine engines components from aircraft, and an improved collector for reducing this method to practice. Collectors known in the art generally have 1) a process tank filled with a remover solution into which the waxed component is fully immersed and the wax is removed; 2) a wax separator tank connected to the process tank for receiving therefrom an overflow of remover solution and removed wax; and 3) a circulating pump for pumping the wax remover solution from the wax separator tank back to the process tank. The collector of the invention further has a level controller operating with microwaves for monitoring the level of remover solution in the wax separator tank and a chemical pump connected to and controlled by the level controller in order to maintain the level of wax remover solution in the wax separator tank close to a preset level by pumping a new batch of remover solution in the wax separator tank.

Abstract: A gravesite covering system for protecting and decorating gravesites and gravestones. The device includes a first member made from a flexible, transparent plastic sheet material. The first member has a main body portion shaped for disposal over a gravestone, and a skirt portion for anchoring the first member to the ground around the gravestone using spikes extending through grommets in the skirt portion. A planar, rectangular member made from a flexible, transparent plastic sheet material is secured along one edge thereof to the first member for covering the ground in front of the gravestone. The rectangular member also includes grommets therein for anchoring the rectangular member to the ground. The first member and the rectangular member each include a pocket for holding a picture of the deceased therein, and are provided with ornamentation for making the gravesite more attractive. The members can also be separately used if only a portion of the gravesite is to be protected and decorated.

Abstract: A method for detecting the presence of any discontinuity in an anticorrosion oil coating applied onto the internal walls of a nautical ballast. The method comprises the steps of (1) adding an oil-soluble tracer to the anticorrosion oil coating prior to its application onto the internal walls of the ballast, the tracer being insoluble in water and rust; inert to rust, water and the oil; and capable of emitting visible light under the effect of a black light; (2) after application of the oil coating, submitting the inside walls coated with the oil to the effect of a black light, and (3) checking the continuity of the visible light that is emitted by the oil coating, whereby the presence of oil is detected by visible light emitted by the tracer and its absence is detected by the absence of any emitted visible light. An anticorrosion oil containing such a tracer is also disclosed.
