Abstract: Provided is a portable cylinder including a tank having a mounting collar coupled to an upper portion of the tank, and a handle assembly attached to the mounting collar. The mounting collar has an upwardly extending portion and a plurality of circumferentially spaced tabs extending radially outwardly from the upwardly extending portion, wherein a respective gap is formed between adjacent ones of the plurality of circumferentially spaced tabs. The handle assembly includes a handle having a shroud portion and a handle portion extending from the shroud portion, and an attachment member configured to be coupled to the shroud portion to prevent rotational movement of the handle relative to the collar, the attachment member having a body, a first projection projecting from a front wall of the body for engaging the shroud portion, and a second projection projecting from a back wall of the body for engaging the shroud portion.

Abstract: A vessel includes a body having an interior surface that defines an interior space. The vessel further includes a flexible membrane located within the interior space of the vessel. The flexible membrane divides the interior space of the vessel into a first chamber and a second chamber. A valve configured to provide selective fluid communication between the first chamber and an exterior of the vessel. The vessel further includes one or more ribs protruding from at least a portion of the interior surface within the first chamber. The one or more ribs create one or more flowpaths configured to allow flow of a contents of the vessel from the first chamber towards an opening of the valve when the flexible membrane is in contact with the one or more ribs. The flexible membrane can include a ribbed structure extending from a surface of the flexible membrane.

Abstract: Provided is a portable gas cylinder including a gas tank having an upper portion, a lower portion, and a collar, the collar including a base secured to the lower portion, a flange extending around and radially outwardly from the base, and a plurality of notches circumferentially spaced around the flange, and a foot ring configured to be attached to the gas tank, the foot ring including a base having an inner surface, an outer surface, a central portion, and a ledge extending around and inward from the central portion, a plurality of circumferentially spaced deflectable longitudinal lock tabs radially outwardly spaced from the central portion for securing the foot ring to the tank, and a plurality of circumferentially spaced rotational lock tabs radially outwardly spaced from the central portion.

Abstract: A sensor assembly is positioned on an exterior of a tank to measure a fluid level within the tank. The tank is modified to include a surface feature and the sensor assembly is slotted within that surface feature. The sensor assembly includes a sensor device and a control circuit configured to drive the sensor device and evaluate readings to determine the fluid level. The sensor assembly further includes a communications interface to enable communication with a management system via a communications network. The management system can store information (e.g. fill status) related to the tank and additionally communicate with vendors or end users to coordinate resupply.
