Abstract: A composite structure comprising i) a release liner comprising a release composition; and ii) a pressure-sensitive adhesive coated backing wherein the pressure-sensitive adhesive has a relatively high storage modulus. The composite structure exhibits a low unwind noise as a result of the release composition employed.

Abstract: Apparatus for producing a waterfall at the edge of a swimming pool, spa or pond, the apparatus including a generally cylindrical reservoir in the water circulation system path, with at least one water discharge metering rod on the axial centerline of the reservoir, configured for directing water in a first direction diametrically opposite an elongate discharge plenum having a second plenum in fluid flow communication therewith for discharging the water into the pool through a sidewall thereof. The apparatus is placed inside the wall on the side of the pool and produces a smooth even sheet of water which is directed away from the side of the pool. The metering rods are constructed for adjusting pressure along the axial length thereof to cause the water pressure inside of the unit to be maintained evenly across its length thereby directing the water out through the throat of the discharge plenum.

Abstract: A circuit, including an electrical load such as a fluorescent lamp, energized through an inverter which is in turn energized from a standard household alternating current voltage source. The output of the inverter is of a low voltage, low current and high frequency. This power is then transmitted by a low current voltage link, in the form of a flexible small gauge, jacketed wire conductor connected across the outputs of the inverter, to the input terminals of a compact step-up transformer located a distance away from the inverter. The power created by the step-up transformer is converted to usable power by the electrical load. The low voltage link need not be enclosed in a raceway.

Abstract: A locking apparatus for portable devices and having a base member for securing to a surface, the base member having a conically tapered receptacle for rotatably receiving a similarly configured bearing plug of a base plate member configured for securing to a portable device. The bearing plug is provided with a reduced diameter portion in alignment with the lock pin of a key operated lock, movement of the lock pin into the neck portion retaining the base plate member relative to the base member while permitting rotation of the base plate member.
