Abstract: A door system includes a corridor sized to allow humans to move through the corridor, the corridor having a first door located at a first end; a second door located at the second end; a controller operatively connected to the first and second doors for controlling the first and second doors; a first sensor oriented to detect an object on the floor, the first sensor operatively connected to the controller and a second sensor oriented to detect an object above the floor in the corridor wherein the second sensor is operatively connected to the controller and the controller is configured to one of: a) turn off the second sensor when the first sensor detects an object on the floor and b) not respond when the second sensor detects and object above the floor when the first sensor detects and object on the floor.

Abstract: A device for aligning a telescopic sight includes two opposing reference cards connected to each other within a common plane by a connecting bar and a level indicator on a surface of at least one card. The alignment device is attached to the front or rear scope base of a firearm, so that the front surfaces of two opposing reference cards appear on either side of the reticle. Once the alignment device is secured to the scope base of the firearm, the reticle may be aligned with the bore axis by rotating the telescopic sight until the horizontal cross hair is parallel with any corresponding pair of reference lines of the reference cards. The alignment device can also include an adapter that allows the alignment device to be mounted to a firearm by coupling to a corresponding slot of a mounting platform.

Abstract: A process is disclosed for the conversion of a hydrocarbon oil feed having a significant content of vanadium to lighter oil products by contacting the feed under conversion conditions in a conversion zone with a catalyst containing a metal additive to immobilize vanadium compounds. Conversion conditions are such that coke and vanadium are deposited on the catalyst in the conversion zone. Coked catalyst is regenerated in the presence of an oxygen containing gas at a temperature sufficient to remove the coke and regenerated catalyst is recycled to the conversion zone for contact with fresh feed. The metal additive is present on the catalyst in an amount sufficient to immobilize the vanadium compounds in the presence of oxygen containing gas at the catalyst regeneration temperature.

Abstract: Contaminating metals including nickel, vanadium, iron and copper are deposited on a fluid cracking catalyst during the processing of carbo-metallic containing oils such as residual oils, reduced crudes or topped crudes. These contaminating metals lead to undesirous side reactions such as dehydrogenation, coking and methyl group removal which adversely affect conversion and gasoline selectively. Furthermore vanadia deactivates the crystalline zeolite component of the catalyst in addition to causing catalyst agglomeration because of its pentoxide melting point by treatment with a reducing gas such as ammonia. The ammonia is added as ammonia or in the presence of diluents such as nitrogen, carbon dioxide, flue gas, fuel gas and steam. The reaction of ammonia with vanadium produces vanadium nitride which is water insoluble and facilitates the disposal of high vanadium containing spent of deactivated catalyst by landfill techniques.

Abstract: A process is disclosed for the treatment of a hydrocarbon oil feed having a significant content of vanadium to provide a higher grade of oil products by contacting the feed under treatment conditions in a treatment zone with sorbent material containing a metal additive to immobilize vanadium compounds. Treatment conditions are such that coke and vanadium are deposited on the sorbent in the treatment zone. Coked sorbent is regenerated in the presence of an oxygen containing gas at a temperature sufficient to remove the coke, and regenerated sorbent is recycled to the treatment zone for contact with fresh feed. The metal additive is present on the sorbent in an amount sufficient to immobilize the vanadium compounds in the presence of oxygen containing gas at the sorbent regeneration temperature. A sorbent composition disclosed comprises a kaolin clay containing the metal additive, which may be introduced into the clay during the treatment process or during sorbent manufacture.

Abstract: A process is disclosed for the treatment of a hydrocarbon oil feed having a significant content of metals to lighter oil products by contacting the feed under conversion conditions in a conversion zone with a catalyst containing a sacrificial trap material sufficient to immobilize Ni-V-Na compounds. Conversion conditions are such that carbonaceous material and metals are deposited on the catalyst in the conversion zone. The catalyst is regenerated in the presence of an oxygen containing gas at a temperature sufficient to remove the carbonaceous deposits, and regenerated catalyst is recycled to the conversion zone for a contact with fresh feed. The sacrificial trap material is present on the catalyst in an amount sufficient to substantially immobilize the metal compounds in the presence of oxygen containing gas at the catalyst regeneration temperature.
