  • Patent number: 11918749
    Abstract: An embodiment of a single use nitrous oxide solution delivery system can be used in a prehospital setting such as in ambulances. A container can be filled with a predetermined relative concentration of nitrous oxide and oxygen gases. The container is sized to be stored in a repository within an automated dispensing cabinet (ADC) for medications. The container is connected to a regulator which includes a main control dial configured to allow a health care provider to adjust the volumetric flow rate of the nitrous oxide and oxygen gas mixture used by a patient. A scavenger can be optionally connected to a patient's mask and configured to remove exhaled gas. Another embodiment of a single use nitrous oxide solution delivery system can be used within hospitals and other medical buildings.

  • Patent number: 9009975
    Abstract: A method of producing a filter unit, such as an air/oil separator, having a tubular filter element bonded at one end to an end cap, is proposed. The method includes the steps of: providing a tubular filter element and an end cap; melting a portion of the end cap; and embedding an end of the filter element into the melted portion of the end cap. The melted portion, on cooling, solidifies to bond the tubular filter element to the end cap. The end cap can be formed of thermoplastic containing an electrically conductive filler. The end cap can be formed of a thermoplastic having a melting point of at least 180 C. The method may further include, after the embedding step, a step of forcing melted thermoplastic from the melted portion radially against a side wall of the tubular filter element.

  • Patent number: 8444735
    Abstract: An air cleaner having a housing body and a removable cover and a filter element, in which the cover and the filter element rotationally interfere with each other by engagement between an inside surface of the cover and an outer radial periphery of the filter element. A filter element includes a pair of end caps, filter media, and an outer wall on the end cap circumscribing the filter media, in which the outer wall is non-circular. A method of installing a filter element into a housing includes orienting a cover over an element and a housing body by engaging an inside surface of the cover and an outer radial periphery of the filter element to rotationally interfere with each other.
