Abstract: An apparatus can include a display, a facial interface, and a connection between the display and facial interface. The display can at least translate or rotate relative to the facial interface via the connection.

Abstract: An oxygen concentration and compression system includes an oxygen concentrator, a boost stage, a compressor, and a portable container. The boost stage receives oxygen enriched gas at a first pressure from the oxygen concentrator. The boost stage includes a pressure increasing device that increases the pressure of the oxygen enriched gas from the first pressure to a second, controlled pressure. The compressor receives the oxygen enriched gas at the second, controlled pressure and compresses the oxygen enriched gas to a third pressure in the portable container for later use by a patient. A patient outlet provides oxygen enriched gas from the oxygen concentrator or the boost stage for use by a patient.

Abstract: Embodiments of oxygen concentrators having a sieve bed that includes a vessel filled with a separation medium are disclosed. The sieve bed vessel at least partially supports one chassis component of the oxygen concentrator with respect to another chassis component. of the oxygen concentrator.

Abstract: A draw latch assembly is formed of three major components including a base member and a latch or bail member interconnected by a link member. The link member and the base member are capable of being pivotally connected in either of two positions rotated 180.degree. from each other so that the reach of the bail member can selectively be either of two different lengths.

Abstract: An enclosure for electrical components comprises an electrically non-conductive molded plastic liquid tight rectangular box-like container having an upwardly open end and defined by side walls joined at upwardly extending corners. Each of the upwardly extending corners includes a vertically extending channel with a vertical access slot. The access slot is narrower than the associated channel to provide a fastener receiving opening for mounting electrical structure within the enclosure. Fasteners are mounted for vertical adjustment in the channels to allow selective positioning of panels or components in the enclosure.

Abstract: Macerator housing has a flange at each end and a flow channel therebetween so that the macerator can be connected into a sewage line for flow therethrough. A pair of power-driven shafts are mounted transversely to the flow direction and each carries a plurality of inter-engaging spaced macerator cutters thereon. The macerator cutters do not reach the outer housing walls, but there is a bypass flow space therearound. Screens are positioned on the inlet side of the housing to direct flow into the macerator cutters, but the screens permit fluid flow through the bypass space around the macerator cutters.
