Abstract: A mobile sanitization system is described that allows the operator of a vehicle such as a forklift to spray a sanitizing solution onto the tires of the vehicle as it is rolling to quickly and efficiently sanitize the tires. The sanitizing solution is configured for killing any microorganisms that may be present in the tires of the vehicle, so that they are not transported into critical areas such as food processing areas.

Abstract: A method is provided for measuring the residual stress in metals. The method includes the steps of drilling one or more holes in a metal workpiece to a preselected depth and mounting one or more acoustic sensors on the metal workpiece and connecting the sensors to an electronic detecting and recording device. A liquid metal capable of penetrating into the metal workpiece placed at the bottom of the hole or holes. A recording is made over a period of time (typically within about two hours) of the magnitude and number of noise events which occur as the liquid metal penetrates into the metal workpiece. The magnitude and number of noise events are then correlated to the internal stress in the region of the workpiece at the bottom of the hole.

Abstract: A pair of grips for holding a specimen which includes a pair of through openings for receiving tension pins and a pair of spaced apart, parallel edges. Each of the grips includes a pin, a Davis adjustable key, and a housing. The Davis adjustable key includes a key housing, a movable key portion and a mechanism to move the key portion relative to the key housing. The housing includes a bore for receiving the Davis adjustable key, a bore for receiving the pin, and a slot for receiving that portion of the specimen which includes the through opening and the edge. The Davis adjustable key bore and said pin bore are substantially parallel to each other. The slot is substantially perpendicular to and completely bisecting the pin bore.

Abstract: An alloy for brazing a silicon die to a gold-plate kovar header consists essentially of 19 to 21 weight percent tin and 0.6 to 0.8 weight percent silicon with the balance being gold. The alloy melts at a temperature below 200.degree. C. which is substantially lower than that of the conventional gold-silicon eutectic alloy.
