Abstract: Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.

Abstract: A lock ring that has a first ring half, a second ring half and a latch assembly. The first ring half includes a nest opening on a front portion of the first ring half, a back end portion of the first ring portion hingedly connected to a back end portion of the second ring half. The latch assembly is connected to a front portion of the second ring half. The latch assembly includes a connection arrangement and a spring system. The connection arrangement is designed to be releasably positionable in the nest opening. The spring system is designed to cause the front portions of the first and second ring halves to be drawn toward one another when the connection arrangement is positioned in the nest opening.

Abstract: Interaction in a virtual space may be facilitated among a super user and one or more users while preserving anonymity between the one or more users. The super user may be an individual that provides guidance or counseling to users within the virtual space regarding personal matters. As such, interactions between the super user and the one or more users may be based at least in part on confidential information respectively associated with the one or more users. The super user can obtain confidential information without exposing the identity of an associated user. Since anonymity is preserved, the one or more users can interact freely with the super user without concern of being identified.

Abstract: A method, executed in a computer system, for opening an electronic market for trading of a security is described. The method includes receiving by the computer system eligible orders and quotes for the security traded in the electronic market and disseminating an order imbalance indicator indicative of predicted trading characteristics of the security at the open of trading. The method also includes determining by the computer system a price or prices at which the maximum shares would be executed and determining which price would minimize any imbalance of eligible orders and executing at least some of the eligible orders at the determined opening price.

Abstract: A method for trading a security in an electronic market includes receiving closing orders and orders for the security traded in the electronic market, disseminating an order imbalance indicator indicative of predicted trading characteristics of the security at the close of trading, determining a closing price for the security based on the closing orders and orders, and executing at least some of the closing orders at the determined closing price.

Abstract: An ultrasonic nondestructive testing system is disclosed which is adapted to display test information representing ultrasonic energy reflected from within an object under test in various modes. In one mode, herein called the set-up mode, a dual display is generated. One of the displays contains a portion of the test information effectively expanded along a horizontal scale, while the other display has a contracted horizontal scale thereby to present essentially all of the test signal. In addition, the other display includes a suitable marker to indicate the location and extent of the test information in the first display. In the other, or test mode, the instrument is adjusted to display only the test information shown in the first display of the set-up mode.
