Abstract: The pre-fabricated wall assembly comprises essentially a rectangular frame structure provided with first and second panels on opposite sides together with inserts in the form of smaller square-shaped frames of the same depth as the distance between the panels so as to function as reinforcing inserts. Each insert is formed of two long and two short sides, the shorter sides fitting between the ends of the longer sides and being offset so as to provide flow passage therethrough. A polyurethane foam is introduced into the interior of the rectangular frame which foam will flow and fill voids in the inserts as well as all voids between the panels and interior of the frame. The resultant assembly provides a highly heat resistant, soundproof and strong wall assembly for use in construction.

Abstract: A safe door bolt is rendered substantially punch-proof by providing as a part of the bolt a hardened plug. This plug has a tapered portion positioned to cause radial expansion of material forming part of the bolt in response to an end blow delivered to the bolt attempting to retract the same into the door. Thus, any force in the form of a sudden axial blow to the end of the door bolt by a burglar will result in the radial expansion of material of the bolt to block its retraction into the guide bore of the safe door thereby frustrating burglary attempts.

Abstract: An electronic apparatus is constructed in the conventional modern (cheapest) way by utilizing one single large etch foiled circuit board with directly soldered in or pluggable (replaceable) chips incorporating micro-circuits. Each chip carries its own top side cold light emitting diode which is not energized during normal operation of the chip. Selected first and second pins of the various plurality of connecting pins for the chip may be temporarily short-circuited such as being touched with the tip of a screw driver. The chip is designed such that shorting of these first and second pins only will energize the light emitting diode only if the chip is good and there is power going to the circuit. Thus, part of each chip is a circuit analyzing (normally dormant) circuit. Determination of malfunctioning chips and replacement thereof is thus greatly simplified for the serviceman.

Abstract: The tensiometer is designed to measure the tension in cables from extremely heavy loads as might occur in large cranes and in oil well rigs. The tensiometer utilizes a pair of spaced tandem pulleys bearing against spaced points on the cable and a central pulley engaging an opposite point intermediate the spaced points so as to force the cable laterally. The tension in the cable tends to straighten the cable and thus exert a load on the central pulley and by measuring this load, a force is developed constituting a function of tension in the cable. The central pulley is removably mounted from the frame structure on an arm. One end of this arm is thus arranged to be pivoted to the frame structure after the cable has been received against the first and second pulleys.
