Patent number: 11963287Abstract: Some embodiments herein are directed to devices and methods for automatically starting a plasma utilizing a wand. In some embodiments, the wand may be used to start a plasma in a plasma torch such as, for example, a microwave plasma torch or an induction plasma torch, as discussed below. The wand may comprise an elongate, hollow wand member comprising a closed distal end, a proximal end, and one or more apertures extending from a hollow interior of the wand member to an exterior surface of the wand member; and an elongate wire member positioned within the hollow interior of the wand member and extending along at least a portion of a length of the wand member, wherein the wire member is configured to be placed in operable communication through the aperture with a power source, such that the power source can be activated to in turn start the plasma within the plasma torch.Type: GrantFiled: September 20, 2021Date of Patent: April 16, 2024Assignee: 6K Inc.Inventors: Zongren Shang, Michael C.

Publication number: 20140326909Abstract: Embodiments of the present disclosure are directed to pressure balanced solenoid control valve for high flow and/or high pressure control applications. An all-sealed integrally formed element functions as both the bellows and spring and is used as a replacement for the combination of both the individual bellows and spring found in existing pressure balanced control valves. The single bellows spring provides a spring force on the movable valve plug and separates opposite sides of the valve plug, wherein a gas passageway is provided between opposite sides of the valve plug so that gas provided at the inlet will flow to opposite sides of the valve plug so as to cancel any pressure forces provided on opposite sides of the valve plug by the pressure of the inlet gas.Type: ApplicationFiled: April 30, 2014Publication date: November 6, 2014Applicant: MKS INSTRUMENTS, INC.Inventors: Junhua Ding, Zongren Shang, Zhifeng Liu
