Abstract: Methods of reducing hydroxyl ions in concrete pore solutions are provided. Such methods are useful in providing resistance to gels which form in concrete due to the alkali-silica (ASR) reaction. The methods comprise adding a salt or mixture thereof to the concrete, in aqueous or solid form, the salt or salt mixture having cations higher in valence than the anions. The methods also comprise adding an acidic phosphate or a silicon-containing alkoxide to the concrete. The methods further comprise resisting and/or inhibiting ASR in airfield runway concrete pore solutions by applying a soluble salt or a mixture of soluble salts in solution or a deicing salt mixture in situ to the runway concrete. All of the above methods are useful in reducing hydroxyl ions in concrete. Such methods can be used to resist ASR in fresh concrete, in concrete that is setting, or in hardened concrete.

Abstract: A transponder that may be used as an RFID tag includes a passive circuit to eliminate the need for an “always on” active RF receiving element to anticipate a wake-up signal for the balance of the transponder electronics. This solution allows the entire active transponder to have all circuit elements in a sleep (standby) state, thus drastically extending battery life or other charge storage device life. Also, a wake-up solution that reduces total energy consumption of an active transponder system by allowing all non-addressed transponders to remain in a sleep (standby) state, thereby reducing total system or collection energy. Also, the transponder and wake-up solution are employed in an asset tracking system.

Abstract: An instrument and method are provided for sealing and joining or hemostatically dividing tissue, which is particularly suitable for laparoscopic and endoscopic surgery. The instrument makes use of the controlled application of a combination of heat and pressure to seal adjacent tissues, to join adjacent tissues, or to anastomose tissues, whereby tissue is heated for an optimal time and at an optimal temperature under optimal pressure to maximize tissue seal strength while minimizing collateral tissue damage. The instrument of the present invention is lightweight and therefore portable, and is particularly useful in field conditions where a source of external power may not be readily available.

Abstract: Free standing above-ground barrier wall 10 that includes a plurality of sheet-pile planks 16, and optionally one or more support elements 12 that are interconnected together using one or more interlocking connectors 22, 24. The sheet-pile plank 16 has a lower edge located proximate a top surface of the ground 14 upon which the free standing above-ground barrier wall 10 is erected in an upstanding, installed configuration. The sheet-pile plank 16 and the support element 12 each constitute sheet-pile components and in the upstanding, installed configuration, a lower portion of the sheet-pile plank 16 is ground engaged and a substantial entirety of the weight of the sheet-pile plank is supported at its engagement with the ground. The engagement may be merely abutting with the plank 16 resting atop the ground, or the lower edge of the plank 16 may be buried into the ground to a certain degree.

Abstract: A retractable hose guide includes a shell assembly that is structured to be embedded into the ground. The shell assembly defines an enclosed space that is open at the top. A guide rod assembly is movably disposed within the shell assembly and structured to move between a first, retracted position, wherein the guide rod assembly is substantially disposed within the shell assembly enclosed space, and a second, extended position, wherein the guide rod assembly extends substantially above the shell assembly enclosed space. A pop-up device includes components on both the shell assembly and the guide rod assembly that act in concert to lock the guide rod assembly in either the first or second position. The pop-up device preferably includes a biasing device structured to bias the guide rod assembly toward the second, extended position. The pop-up device is structured to be actuated by a generally linear movement of the guide rod assembly.

Abstract: An improved stator (28) for rotating electrical machines with single-layer stator windings consisting of a plurality of pre-formed coils (22) of equal angular pitch. The stator (28) has a first cylindrical surface in which a plurality of circumferentially spaced winding slots (30) are formed and in which the axially-extending winding runs (24) of the pre-formed coils (22) are positioned. The two winding runs (24) of each coil (22) will each be positioned in a winding slot (30) and the two winding slots (30) that receive the coil (22) define a winding slot pair. The improvement arises from the fact that the winding slots (30) of each winding slot pair extend into the stator (28) in substantially parallel directions. This means that the axially-extending winding runs (24) of each pre-formed coil (22) may also be substantially parallel and need not be angled towards each other.
