Abstract: An ultrasonic flow meter assembly includes a meter housing comprising an upper housing and a lower housing, the lower housing defining a first piezo mount, a second piezo mount, a first reflector mount and a second reflector mount; a first piezoelectric transducer supported on the first piezo mount and a second piezoelectric transducer supported on the second piezo mount; a first reflector mounted to the first reflector mount and defining a first reflective surface, the first reflective surface vertically aligned with the first piezoelectric transducer; and a second reflector mounted to the second reflector mount and defining a second reflective surface, the second reflective surface vertically aligned with the second piezoelectric transducer; wherein the first and second reflectors are configured to reflect ultrasonic signals from the first piezoelectric transducer to the second piezoelectric transducer.

Abstract: Disclosed is a thermoplastic elastomer composition having a superior low-temperature flexibility is provided. The thermoplastic elastomer composition may include an amount of about 10 to 15 wt % of a polypropylene-ethylene copolymer; an amount of about 70 to 85 wt % of a thermoplastic elastomer including an olefin-based thermoplastic elastomer and a styrene-based thermoplastic elastomer; an amount of about 5 to 10 wt % of a softener; an amount of about 3 to 5 wt % of a reinforcing agent; and an amount of about 1 wt % or less but greater than 0 wt % of a UV stabilizer based on the total weight of the thermoplastic elastomer composition.

Abstract: Disclosed is an anchor encased in a box-shaped frame embedded in a framework of a house, for hanging a variety of objects. The anchor includes a box-shaped frame having an open lower end, the frame being embedded in a ceiling slab. An anchor bolt is fixed in the box-shaped frame and has a hook at a first end, for hanging objects. A plurality of fixing flanges is attached to the outer surface of the box-shaped frame, for securely fixing the box-shaped frame to the ceiling slab, the fixing flanges being present in multiple rows. A cover is detachably attached to the lower end of the box-shaped frame. The anchor further includes a threaded shaft fixed to the opposite inner surfaces of the box-shaped frame and installed to cross the inner space of the box-shaped frame, and a rotatable pipe installed in a manner so as to surround the threaded shaft.
