Abstract: A CMOS circuit comprises CMOS MOSFETs having n-type and p-type gates on the same substrate, wherein the substrate is divided into regions of n-type and p-type diffusions, and those diffusions are contained within a deeper n-type diffusion, used to junction isolate components within the deeper n-type diffusion from components outside of the deeper n-type diffusion.

Abstract: Walk-through safety devices for ladders meeting ANSI and OSHA standards are positioned at the top end of the ladder and are comprised of two, juxtapose-position, mirror image members. One each is mounted on a respective ladder side rail, Each member includes a sleeve (or rectangular tube) which slides down over a respective ladder side rail, a pressure bar which is tightened against the side rail with a knob operated screw, a pivoting engaging lock plate, and a lock plate tab cover plate. A horizontal hand grip framework is held outboard of the ladder side rails vertically upward, being at an angle of about 14.5 degrees upward from the longitudinal axis of the sleeve and side rail when resting against a structure. The framework is held in that position by a flared tube which is bent in two directions.

Abstract: A method is described of injecting CO2 into an aquifer or a depleted hydrocarbon reservoir (211) via at least one injection well (202) that penetrates said aquifer or reservoir, wherein the injection well is provided with an injection tubing (203) that is in sealing engagement with the injection well. The injection tubing terminates at or immediately above the interval of the aquifer or the reservoir into which the CO2 is to be injected and the injection tubing is provided with a fluid injection control valve (208) at or near the bottom thereof which is closed or closes when the pressure above the valve is less than a pre-set pressure value and opens or reopens when the pressure above the valve is at or greater than said pre-set pressure value, the pre-set pressure value being selected such that the CO2 in the injection tubing is maintained in a liquid or supercritical state.

Abstract: A safety rail assembly for mounting on a deck of a transport carrier which transports and supports thereon at least one automobile having at least one of passenger and driver-side doors. The portable safety rail assembly includes a handrail extending horizontally relative to the upper surface of the deck and support posts for supporting the handrail. Each support post may be removeably mounted to the deck to permit selective vertical displacement of the handrail relative to the upper surface of the deck for positioning the handrail at a desired height above the upper edge of a door of the transported vehicle. The desired height permits unobstructed opening and closing of the doors and safe entrance into and egress from the interior of the automobile.
