Abstract: A polypropylene composition comprises an isotactic polypropylene homopolymer resin that is suitable to form an injected molded article exhibiting less than about 60% haze, as determined by ASTM D1003, at a thickness of 0.05 inch without clarity-enhancing agents. The polypropylene composition has particular application to injection molded articles and may have a melt flow rate of from about 0.1 g/10 min to about 150 g/10 min as determined by ASTM D-1238, Procedure B. The resin may be prepared using a metallocene catalyst, and the composition may include clarity-enhancing agents for even greater clarity improvements.

Abstract: An attachment system for a boat cover using an insert strip press fit in a conventional rub rail channel fixed to the boat hull. The insert strip has a lengthwise slot which is configured to mate with a series of retainer elements attached about the perimeter of the cover. Each retainer element has a portion configured to be received in the insert strip slot and locked thereto by being turned sideways. In one embodiment, the retainers have a flattened pin which can be pushed into the insert strip slot and turned, a larger head portion thereby fit to a larger interior section of the slot to be locked therein. In another embodiment the retainer elements each have a pair of spread projections which are compressed together to be able to be pushed in through the slot entry section and which spring apart in the interior slot section, to be locked therein. A threaded pin can be advanced between the projections to produce a positive spreading of the projections.

The water heater includes a tank to hold water, a heating element, an electrode, and a control circuit. The control circuit includes a variable voltage supply, a voltage sensor, and a current sensor. The control circuit is configured to controllably apply a voltage to the electrode, determine the potential of the electrode relative to the tank with the voltage sensor when the voltage does not power the electrode, determine a current applied to the tank after the voltage powers the electrode, determine a conductivity state of the water in the tank based on the electrode potential and the current, and define the voltage applied to the powered electrode based on the conductivity state. The control circuit of the water heater can also determine whether the water heater is in a dry-fire state.

Abstract: Abstract of the Disclosure A heat trap for use in a conduit through which fluid flows. The heat trap comprises a unitary body having a central bore extending therethrough, and first and second blocking portions having on a circumferential edge respective first and second resilient hinge portions. Both of the blocking portions substantially entirely block the central bore when in an at-rest condition. The first and second hinge portions hingedly interconnect the blocking portions to the unitary body in cantilever fashion and permit resilient deflection of the blocking portions on the hinge portions in response to fluid flow through the conduit. The resilient hinges also provide for the resilient return of the blocking portions to the at-rest condition in the absence of fluid flow through the conduit.

The method of the present invention involves manipulating expression of Eph receptors or their functional equivalents to increase or decrease expression or function depending on the condition being treated.

Abstract: A harness for use in windsurfing which includes an adjustable wrist strap for securing the harness to the wrist of the wearer, an elongated support connected at one end to the wrist strap and which includes a rigid end portion which defines a curved hook for capturing a generally rounded in section boom. The elongated support further includes an intermediate adjustable finger loop which enables an immediate unhooking of the end portion by a backward bending of the hand at the wrist pulling the hook out of engagement with the boom. The harness transfers some or all of the force required to hold the boom to the wearer's forearm to reduce the effort required.

Abstract: An irrigation control device (12) with a controller (14), antenna (16), power supply (70) and battery charging device (72), such as a solar array, all contained within a housing, such as a rotor body (90). The controller (14) receives signals through the antenna (16). The controller (14) updates one or more watering schedules stored in a memory module (32), based on the received signals, and generates control signals to execute a watering schedule. The battery charging device (72) recharges the power supply (70) and the irrigation control device requires no external electrical connections for power or control. Control signals are generated in a central controller (18) remote from the rotor (12), and are preferably transmitted to the rotor antenna (16) through a commercial paging or other type of public broadcast network (20, 22, 24).

Abstract: A system and method are presented for optimally retuning channel equipment in a base station serving a cell from a first channel group to a second channel group, without dropping pending calls and maintaining channel separation throughout the retune above a predetermined threshold. A sequential order for retuning the channel equipment is determined which insures that every channel equipment is retuned to a channel that is separated from the operating channels of each other channel equipment in a cell by a certain threshold. After determining the appropriate order, the status of each channel equipment is checked to determine whether the channel equipment is busy or idle. Based on the status of each channel equipment, the channel equipment are simultaneously retuned in groups of the size equivalent to the number of idle channel equipment in the determined sequential order.
