Abstract: A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller plate resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently. At its exit, the proximal end of the tube drains oil through an inner conduit of an adapter at a penetration in the wall of the tank. The adapter forms an annulus around the inner conduit draining tank bottoms directly from the tank.

Abstract: A wearable augmented reality device is described. The device comprises a headband, brim, optical displays, and environmental sensors. The headband wraps at least partially around a head of a user and distributes the weight of components of the device across the head of the user, supporting the device. The brim is coupled to the headband such that the brim extends away from the headband, over the eyes of the user. The brim includes a heatsink that releases heat from the electronics of the device into the environment. The optical displays are coupled to the underside of the brim. The optical displays both present image light and allow environmental light to pass through. The environmental sensors are couples to the forward edge of the brim and capture data about the environment.

Abstract: A mold assembly and method for molding two concrete blocks in face-to-face non-contacting relationship forms blocks having smooth front faces. The mold assembly includes a mold box having two mold cavities configured to form two blocks in face-to-face non-contacting relationship. A common partition plate separates the two mold cavities and opposite sides of the partition plate form the smooth front faces of the blocks. The two mold cavities are each configured to form a block having a raised front face with a beveled edge around its entire perimeter and a border around the entire perimeter of the beveled edge. The portions of the border at the top and the sides of the raised front face are curved and the portion of the border at the bottom of the raised front face is straight. A core bar is slidably inserted into the mold box beneath the bottom of the partition plate, and opposite sides of the core bar extend into and form the front bottom portions of the mold cavities.

Abstract: The present disclosure generally relates to paraffin inhibitor formulations useful to inhibit formation of paraffin aggregates and paraffin deposition on the metal surfaces during hydrocarbon production, transportation, and refining process. The paraffin inhibitor formulations can lower the pour point of the crude oil, improve the flow characteristics of the oil, inhibit paraffin deposition on metal surfaces and disperse paraffin aggregates in the oil. Methods of making and using the paraffin inhibitor formulations are further disclosed.

Abstract: A head-mounted display (HMD) includes a hybrid fan, a printed circuit board (PCB) with one or more electronic components and a heat pipe to dissipate heat. The hybrid fan has a center axis extending from a rear side of the HMD to a front side of the HMD. The hybrid fan pulls air from a rear side of the HMD. The heat pipe has an end coupled to the PCB. The heat pipe partially surrounds a periphery of the hybrid fan and transfers heat away from at least the PCB. The HMD further includes a side cover and a front cover. The side cover encloses the hybrid fan, the PCB and the heat pipe. The front cover is attached to the side cover with a slit between an outer edge of the front cover and an outer edge of the side cover to discharge air from the hybrid fan.

Abstract: 1-(3,4-Dihydro-1H-pyrido[4, 3-b]indol-2(5H)-yl)-2-hydroxyethanones are disclosed. The compounds are inhibitors of human cGAS in interferon-producing cell types. They are thus useful as therapeutic agents for treating cGAS-related autoimmune diseases in humans.

Abstract: Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water is concentrated in a reverse osmosis step and salt from the resulting solution is removed in supercritical conditions prior to destruction of PFAS in supercritical conditions.

Abstract: Passive monitoring the integrity of current sensing devices and associated circuitry in GFCI and AFCI protective devices is provided. A protection circuit interrupter employs a capacitively coupled noise signal obtained by an arrangement of one or both of the line side arms relative to a Rogowski coil. The noise signal is monitored while the line and load sides of a protective circuit interrupter are disconnected, and the connection of the line and load sides disabled if the noise signal fails to correlate sufficiently to a reference noise cycle. When the line and load sides are connected, the RMS value of the observed current signal is monitored such that the line and load sides are disconnected if the observed current signal fails to meet an RMS threshold. The observed current signal is compensated by subtracting the reference noise cycle prior to monitoring for the fault condition applicable to the protective device.
