Patent number: 11650010Abstract: The present invention relates to an adsorption process for xenon recovery from a cryogenic liquid or gas stream wherein a bed of adsorbent is contacted with a xenon-containing liquid or gas stream selectively adsorbing the xenon from said stream. The adsorption bed is operated to at least near full breakthrough with xenon to enable a deep rejection of other stream components, prior to regeneration using the temperature swing method. After the stripping step, the xenon adsorbent bed is drained to clear out the liquid residue left in the nonselective void space and the xenon molecules in those void spaces is recycled upstream to the ASU distillation column for increasing xenon recovery. The xenon adsorbent bed is optionally purged with oxygen, followed by purging with gaseous argon at cryogenic temperature (?160 K) to displace the oxygen co-adsorbed on the AgX adsorbent due to higher selectivity of argon over oxygen on the AgX adsorbent.Type: GrantFiled: December 12, 2018Date of Patent: May 16, 2023Assignee: PRAXAIR TECHNOLOGY, INC.Inventors: Hai Du, Michael J. Dray, James P. Meagher, Steven R. Falta

Patent number: 5534672Abstract: A switch assembly has dual spring biased plungers which operate several switches within a single housing. The dual plungers act independently of one another to provide switch redundancy if required. The plungers have rectangular surfaces with cams, and the switches have cam followers which operate the switches. In an alternative application, some of the switches may be replaced with a printed circuit board and a plunger with multi-finger wiping contacts. The printed circuit board and plunger with multi-finger wiping contacts arrangement allows the switch to produce a signal that is related to the distance of pedal movement. Additionally, a capacitor is provided on the housing for the purposes of filtering any electrical signal produced by electrical contact arching in a switch used in a high voltage circuit. The capacitor is held in the switch assembly by a box and a holding clip. The capacitor's placement in the switching circuit is such that it is in parallel with the switch.Type: GrantFiled: February 6, 1995Date of Patent: July 9, 1996Assignee: Emerson Electric Co.Inventor: James P.

Patent number: 5006677Abstract: A housing includes a switch chamber and a plunger chamber communicating with the switch chamber. A plunger is slidable within the plunger chamber. Cam surfaces on the plunger operate electrical switches in the switch chamber. There is an axial channel in the plunger, and a slot through the plunger wall communicates with the channel. A vacuum passageway passes from one side of the housing, into the channel, and a solid extension of the passageway passes through the slot, and into a hole in the opposite wall of the housing. As the plunger moves in and out, the slot slides on the extension to guide to stabilize the plunger. A vent hole in the vacuum passageway opens into the channel. A sealing member slides in the channel along the axis of the plunger, alternately sealing and unsealing the vent hole as the plunger moves. A spring seated between the plunger and the sealing member permits the plunger to continue moving when the sealing member is seated in the passageway vent hole.Type: GrantFiled: January 31, 1990Date of Patent: April 9, 1991Assignee: Emhart Industries Inc.Inventors: John W.
