  • Patent number: 11195674
    Abstract: A break-before-make (BB4M) circuit topology is disclosed for use with a multiplexer that eliminates shoot-through current between analog inputs and also between an analog input and analog output. The BB4M circuit generates a pulse that disables an existing selected channel before enabling a newly selected channel or gate driver, and is suitable for use in high-radiation or outer space operating environments.
    Type: Grant

  • Patent number: 5325897
    Abstract: A fluid catch container for sampling and drain valves provides for the containment of any residue which may leak or drip from the outlet of such a valve. The container is selectively openable and closable, providing easy access for the taking of a sample or for the draining of fluid from the outlet. A rotatable closure serves to prevent the flooding of the catch container due to rain or other agent(s) and the undesirable distribution of any residue due to wind action. The base of the container is removable for emptying and cleaning, and alternatively may be replaced with a fitting for a larger residue collection container. The device is preferably formed of corrosion resistant materials, such as stainless steel, although other materials (e.g., plastics, etc.) may be used. The device is particularly useful in the petroleum, petrochemical, and chemical industries, or any environment where fluid samples must be taken on a regular basis from regular points in a processing system.
