Abstract: The present invention relates to a catalyst composition. More particularly, the present invention relates to a catalyst composition comprising a low SAR zeolite, copper in an amount of at least 2 wt %; and a rare earth element. The present invention also relates to a method for the manufacture of a catalyst composition. The present invention further relates to a catalyst article comprising a catalyst composition and a method for the treatment of an exhaust gas which comprises contacting an exhaust gas with a catalyst article comprising a catalyst composition.

Abstract: Catalyst compositions and methods of preparation comprising: preparing a promoter metal-molecular sieve catalyst composition comprising a promoter metal and a molecular sieve; and incorporating an iron salt into the promoter metal-molecular sieve catalyst composition.

Abstract: Catalyst compositions and methods of preparation comprising: exchanging a rare earth element into a molecular sieve; incorporating a promoter metal into the molecular sieve; wherein the rare earth element exchanging step and the promoter metal incorporation step are performed as separate steps.

Abstract: A method for retrieving storage racks in a tank freezer includes positioning a retrieval crane adjacent to the tank freezer such that a base of the retrieval crane is positionable underneath a bottom wall of a tank body. The retrieval crane includes a boom extending upwardly and laterally outwardly over the base so that a retention hook at a free end of a cable associated with the boom may be extended or retracted relative to the tank freezer. More specifically, the cable may be moved to extend the hook through the opening of the tank freezer into a storage space, and then retract the hook to lift and then hold a selected storage rack in a hoisted position. The method avoids the use of manual hoisting of storage racks, and the retrieval crane may be used with any of a plurality of similar tank freezers located in a larger facility.

Abstract: A curtain ring having a fragrance-releasing material mounted on its inner diameter. The material is selected so that the fragrance will only be released when the consumer opens or closes the curtain, that is, only when the material is rubbed against the curtain rod.

Abstract: A surgical instrument stand useful for the compact organizing and counting of a plurality of ring-handled surgical instruments being held in a parallel and vertical position. The stand is formed of autoclavable polymeric material and embodies an elongated rectangular body with the lower portion or base having a top wall acting as a resting wall for the surgical instruments. Vertical compartments are formed from equal distant partitions thus holding the ring-handled surgical instruments in a vertical position for easy use and stability during surgery. An adhesive strip on the bottom stabilizes the stand in relation to other surfaces.

Abstract: An apparatus and method for testing an access time of a macro embedded in a LSI chip. The apparatus includes a logical gate connected to the output latches of the macro, thereby controlling the access time of the macro, and a test latch for determining an on-chip delay time between a test signal for enabling the output latches and an input signal for enabling the macro. The method includes the steps of determining the on-chip delay time between the test signal and the input signal, thereby allowing the test signal to be synchronized with the input signal, supplying the synchronized test signal to the output latches for a manufacturer specified macro access time, and testing the latched output data from the macro.
