  • Patent number: 10888818
    Abstract: An integrated mercaptan extraction and/or sweetening and thermal oxidation and flue gas treatment process for a wide variety of sulfur, naphthenic, phenolic/cresylic contaminated waste streams is described. It provides comprehensive treatment for the safe disposal of sulfidic, naphthenic, phenolic/cresylic spent caustic streams, disulfide streams, spent air streams, spent mixed amine and caustic streams (also known as COS solvent streams) from sulfur treating processes. It allows the use of regenerated spent caustic in the sulfur oxide removal section of the thermal oxidation system reducing the need for fresh NaOH. It may also contain an integrated make-up water system. The integration allows the use of the liquefied petroleum gas or other hydrocarbon feeds to the respective extraction or sweetening process to offset external fuel gas requirements for the thermal oxidation system and for the push/pull system of the spent caustic surge drum and optional hydrocarbon surge drum.

  • Patent number: 10811817
    Abstract: An electrical connector includes a housing having a mating end and a wire end with a base and terminal channels extending through the base into the mating end. The terminal channels receive terminals mated with a mating electrical connector. The base has a wire support supporting wires extending from the terminals. The wire support includes support walls forming wire channels. A wire dress cover is coupled to the wire support and includes an end wall and wire pushers extending from the end wall. The wire pushers load the wires into the wire channels. The wire pushers are received in the wire channels to hold the wires in the wire channels. The wires are supported at the rear by the wire pushers and at both sides by the support walls to provide strain relief for the wires in the wire support.

  • Patent number: 10729891
    Abstract: Disclosed are devices, systems, and methods for providing access to a patient. The patient access device comprises a proximal end, a distal end and a lumen therethrough. The patient access device further comprises a hollow shaft, an input port and a liquid supply port. At least a portion of the lumen passes through the shaft. The input port is coupled to the lumen, and the lumen and the input port are constructed and arranged to receive an elongate probe. The liquid supply port is in fluid communication with the lumen. The patient access is constructed and arranged to reduce gas from exiting the distal end while a portion of the elongate probe is positioned in the patient access device.

  • Publication number: 20200115301
    Abstract: A process for recovering ethylene from an FCC absorber off-gas stream comprising ethylene, ethane and heavier hydrocarbons and light gases involves removing hydrogen, nitrogen, sulfur species, carbon monoxide/dioxide, methane and other impurities from the off-gas. An absorption zone is upstream of an acetylene selective hydrotreating reactor to remove acid gases. An adsorption zone is downstream of the selective hydrotreating reactor to remove impurities that can impair ethylene recovery.

  • Publication number: 20190159729
    Abstract: Provided is a flex-PCB catheter device that is configured to be inserted into a body lumen. The flex-PCB catheter comprises an elongate shaft, an expandable assembly, a flexible printed circuit board (flex-PCB) substrate, a plurality of electronic components and a plurality of communication paths. The elongate shaft comprises a proximal end and a distal end. The expandable assembly is configured to transition from a radially compact state to a radially expanded state. The plurality of electronic elements are coupled to the flex-PCB substrate and are configured to receive and/or transmit an electric signal. The plurality of communication paths are positioned on and/or within the flex-PCB substrate. The communication paths selectively couple the plurality of electronic elements to a plurality of electrical contacts configured to electrically connect to an electronic module configured to process the electrical signal. The flex-PCB substrate can have multiple layers, including one or more metallic layers.

  • Patent number: 9397445
    Abstract: An electrical connector system is provided that includes a plug connector, a connector position assurance (CPA) device, and a header connector. The plug connector includes a housing and a deflectable primary latch that extends from the housing. The housing includes a lug protruding therefrom. The CPA device is mounted to the plug connector and is configured to translate relative to the plug connector. The CPA device includes a deflectable retention latch having a head at a distal end thereof. The header connector has a latching surface that engages the primary latch of the plug connector. When the plug connector mates to the header connector, a tab of the header connector deflects the retention latch of the CPA device to allow the CPA device to be translated in a locking direction beyond the lug to a locked position. The head of the retention latch blocks deflection of the primary latch.
