Abstract: The invention provides an electrical device activated by conductive ink patterns applied to an activation strip which includes a plurality of electrical contacts disposed in an array adjacent to each other. Also included is reader circuitry connected to said plurality of electrical contacts and a housing arranged to contain said reader circuitry and to locate the plurality of electrical contacts. The invention is arranged so that the housing locates the plurality of contacts to facilitate movement of an activation strip relative to the contacts with the contacts touching the activation strip and the contacts arrayed across the width of the activation strip. The provision of an activation strip is also within the scope of the invention.

Abstract: A device for securing a hazardous material container on a containment assembly includes four corner brackets and four adjustable straps. Each of the corner brackets are removably mounted to a corner of the containment assembly. Each bracket has a hole formed therein. The first adjustable strap is attached to one corner of the material container and extends down through the hole in the first bracket and up to the opposite corner of the container. The second strap is likewise attached to a second corner of the container, extends down through a hole in the second corner bracket and is secured to an opposite corner. The third and fourth straps are similarly attached. The tension on the straps is adjustable to hold the container securely on the containment assembly.

Abstract: An improved portable pallet structure for supporting material carrying containers including a confined chamber having a plurality of access passages separate from the confined chamber to accommodate lifting members and including a material pervious support platform mounted above the confined chamber whereby materials spilled from containers supported thereby are collected in the confined chamber.

Abstract: A three flanged polyolefin tank fitting wherein two of the flanges are integrally connected to a pipe having a threaded portion one one end thereof, one flange being connected to the opposite end of the pipe and another flange being positioned between the threaded end portion and the first-mentioned flange. The third flange consists of a flange connector having axially extending bolts extending through the second flange. The inner faces of the second and third flanges are provided with compressible gaskets, and a siphon drain is connectable to the threaded end of the pipe.

Abstract: A conveyor of the low density type comprises two spaced-apart roller assemblies around which an endless wire is entrained to form upper and lower flights consisting of parallel spaced-apart wire lengths. Each roller assembly includes grooved discs or pulleys to support the successive lengths of wire of the flights, the pulleys being mounted on a shaft so as to be independently rotatable. A drive to one of the assemblies includes a slipping clutch to an end pulley, and the remaining pulleys are in frictional engagement so that the drive is transmitted to all the pulleys in that assembly.
