  • Neck strap for supporting an article
    Patent number: 5244135
    Abstract: A neck strap for supporting an article which comprises a flexible cord terminating in aglets at either end. The strap is passed through a slot in a flange at one end of the container. The aglets are inserted into opposite ends of a length of flexible hollow tubing with the outside diameter of the aglet and the inside diameter of the tubing being of dimensions such that there is a friction fit between the aglets and the tubing. The reduced force required for separation of the aglet and tubing prevents injury to the wearer.

  • Stabilizing spent hydrotreating catalyst for reprocessing or storage
    Patent number: 4900713
    Abstract: A method of stabilizing pyrophoric hydrotreating catalyst drums has been discovered. The dry catalyst is introduced into drums which have been purged with an inert gas such as nitrogen or carbon dioxide. A continuous layer of gelatinized starch is applied to the top of the catalyst, sealing it from air. The drum lid is clamped on and the catalyst is stored or transported. The gelatinized starch seal does not impair the catalyst for regeneration or metals reclaiming.
