  • Publication number: 20220362510
    Abstract: A catheter adapter may include a distal end, a proximal end, an inner surface extending through the distal end and the proximal end and forming a lumen, and a side port forming a side port pathway through a sidewall of the catheter adapter and in fluid communication with the lumen. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include a septum disposed within the lumen proximal to the side port pathway. The catheter assembly may include one or more features to facilitate flushing of the catheter assembly: a diameter of the side port may increase in a distal direction; a portion of the inner surface proximal to the catheter and distal to the septum may include multiple grooves; the side port pathway may include a non-cylindrical portion; an insert; a rotation element; and a pivot element.

  • Publication number: 20220275298
    Abstract: Pre-ground plastics of small particle size not more than 2 mm are co-fed into a solid fossil fuel fed entrained flow partial oxidation gasifier. High solids concentrations in the feedstock stream can be obtained without significant impact on the feedstock stream stability and pumpability. A consistent quality of syngas can be continuously produced, including generation of carbon dioxide and a carbon monoxide/hydrogen ratio while stably operating the gasifier and avoiding the high tar generation of fluidized bed or fixed bed waste gasifiers and without impacting the operations of the gasifier. The subsequent syngas produced from this material can be used to produce a wide range of chemicals.

  • Publication number: 20220162344
    Abstract: High concentrations of recycle polymer are gasified in a partial oxidation gasifier to make a syngas useful to make a variety of chemicals and polymers, such as cellulose ester. Polymers such as cellulose esters can be made that are obtained from sustainable sources, recycle sources, and are biodegradable. Circularity in the manufacture of textiles and/or plastics made from the fibers of such cellulose esters can now be achieved. The process of making such a syngas from high concentrations of recycle polymer (e.g. textiles and/or plastics) includes campaigning for the production of syngas.

  • Patent number: 11164381
    Abstract: An improved system to provide a clothing model in augmented reality and/or virtual reality is disclosed. In one embodiment, the system provides a fully simulated garment, on the user's device, in an augmented reality or virtual reality display. In one embodiment, the process uses a parameterized smart garment model which enables real-time interaction with the garment on a device such as a mobile phone or tablet, with limited memory and processing power. In one embodiment, the system permits nearly instantaneous alteration of garment sizes. Because the garment is modeled to accurately reflect physical details, the lay of the garment changes as the size of the garment or body changes.

  • Patent number: 10814106
    Abstract: An IV catheter system may have a catheter component and a needle component. The catheter component may have a catheter hub, a cannula extending distally from the catheter hub, and a push feature extending outward from the catheter hub. The push feature may have an outer surface that receives contact from a digit to move the IV catheter system from an insertion configuration, in which the needle is within the cannula, to a fluid delivery configuration, in which the needle is outside the catheter hub. The needle component may have a needle hub and a needle extending distally from the needle hub along an axis. The push feature may be formed of a flexible material that causes the push feature, in response to pressure exerted on the outer surface by a dressing securing the catheter component to a patient, to deflect the outer surface toward the cannula axis.
