A remote-control assembly for adjusting a flow of oxygen from an oxygen concentrator includes an inducer module and remote controller. The inducer module, which comprises a receiver, is selectively couplable to the oxygen concentrator so that the inducer module is operationally coupled to a flow rate control knob of the oxygen concentrator. The remote controller comprises a transmitter and is positioned to selectively and wirelessly communicate a command to the inducer module, via the receiver, positioning the inducer module to turn the flow rate control knob to adjust a flow of oxygen from the oxygen concentrator.

A retrofit motorized actuator assembly is attachable to a portion of a fluid pipe having a manually actuated valve connected in series. The valve includes a cantilevered valve handle manually rotatable about a valve axis. The retrofit motorized actuator assembly includes a motorized actuator including a drive shaft extension rotatably controllable by the motorized actuator about a drive shaft axis. A mounting assembly is configured to fixedly attach to the portion of the fluid pipe and also fixedly position the motorized actuator wherein the drive shaft axis of the motorized actuator is aligned with the valve axis. A quick connect clamp is configured to fixedly attach together both the drive shaft extension and the cantilevered valve handle. The quick connect clamp is configured to be attachable and removable with just the use of a user's hands without the need for auxiliary tools.

Pressurized gas bottles with integrated valves, in which a plurality of functional supports are integrated in an extraction unit, are equipped with complex fall protection means. Moreover, in such a valve, a new approval procedure is carried out for the entire valve in the event of multiple modifications, for example when supplementing it with an additional function. In order to reduce the effort associated with this, an extraction fitting for a pressurized gas bottle is provided with a modular design, wherein a base module comprising the shut-off member and a fall protection device securing the shut-off member complies with legal requirements regarding fall protection and the shut-off device of the pressurized gas bottle. All further functionalities of the extraction fitting are integrated in at least one additional module, which is connected to the base module in a fixed but removable manner and without impairing the fall safety.

A construction unit (1, 2) forms part of a gas heater and includes a valve (9) which is actuatable by way of a stem (10). The stem (10) includes positive-fit device. The stem (10) is controllable from the outside via a tool which can be brought into engagement with the positive fit device. A detent engagement device (18, 27) holds the tool (21) in engagement with the stem (10), so that the valve is controllable without the aid of outside tools.

A pipe fitting having a base configured to engage with a pipe, the base having a mounting seat configured to engage directly with the pipe, a base ring configured to engage with the mounting seat, and a base flange configured to engage with the base ring, a top hat configured to engage with the base, the top hat having a top cap, a top hat ring configured to engage with the top cap, and a top hat flange configured to engage with the top hat ring, wherein the top hat flange is further configured to engage with the base flange to form a fitting cavity. A pipe flow controller may be in fluid communication with the internal pipe volume through a threaded nipple, while also being securely housed within the fitting cavity, thus protecting the pipe flow controller from corrosion, impacts and other forms of damage to prevent leakage.

The present invention provides a sub-frame (10) for a valve body (12) having two or more location surfaces (14, 16), said sub-frame (10) comprising a first and a second portion (10a, 10b) having mutually confronting contact surfaces (18a, 18b), sides (20a, 20b) and front and back surfaces (22a, 22b) and mutually confronting engagement surfaces (24a, 24b and 26a, 26b) wherein said mutually confronting contact surfaces (18a, 18b) are shaped to engage with each other upon placement together of the two portions (10a, 10b) and said mutually confronting engagement surfaces (24a, 24b and 26a, 26b) are shaped to engage with one or other of said one or more location surfaces (14, 16) on the valve body (12).
