Abstract: A method of preventing condensation on equipment inside a temperature-controlled enclosure comprises measuring the temperature in at least one location inside the enclosure. The temperature inside the enclosure is compared with a safe temperature, at which the risk of condensation is reduced. The temperature inside the enclosure is increased until the safe temperature is achieved. A user is then notified that it is safe to access the enclosure.

Abstract: Rain gutter and downspout cleaning tongs. The rain gutter cleaning tongs include a pair of arms, each having a distal portion and a proximal portion that are arranged at obtuse angles relative to each other. A gripping head is located at a distal end of the distal portion of each arm. The proximal arm portions are pivotally attached to each other and are spring loaded to bias their gripping surfaces away from each other. Optionally, a guide is attached to one of the arms for guiding the two arms relative to each other during operation.

Abstract: The disclosure provides an improved cooling system and associated cabinet for electronic equipment, and optionally, a backup ventilation system for cooling related failures. Generally, the disclosure includes a high capacity closed loop refrigeration system in a modified cabinet, while accommodating standard sized computer equipment. Further, the system provides directed heat removal by altering typical airflow paths within the cabinet. The backup ventilation system is powered by auxiliary power in the case of power failure and uses the same fan(s) for ventilation as is used for cooling. The disclosure provides a more efficient, higher capacity cooling cabinet in less space than otherwise known in the art. Further, the cooling system can anticipate heat loads and therefore operate in a predictive capacity by monitoring input power to the electronic equipment and adjusting the cooling for the expected increase or decrease in heat load generated based on the input power.

Abstract: An assembly for selectively supplying particulate material to an air seeder, an agricultural implement able to selectively supply and dispense particulate material into the ground and a method of selectively dispensing particulate material into the ground are provided. The assembly has at least one supply receptacle for receiving particulate material from a source and a metering roller for supplying the material to an air seeder. The assembly is operative to selectively supply the material to the air seeder and prevent the material from being supplied to the air seeder. The implement can use the assembly to selectively supply particulate material to ground engaging openers where the particulate material will be dispensed into the ground. Particulate material can be selectively supplied to the implement when it is desired to have the particulate material dispensed into the ground and then prevented from being supplied to the implement when it is not desirable.

Abstract: The present invention relates to an energy conversion device including a roofing material having one or more open channels and one or more photovoltaic modules, characterised in that the one or more photovoltaic modules is bonded directly or indirectly to the roofing material so as to form one or more covered channels through which fluid can flow. In this manner an energy conversion device may be formed in a standard roofing material combining the benefits of Photovoltaic modules to generate electricity and a solar thermal collector to provide heat from the Sun in a single integrated device.

Abstract: A mounting for solar panels has fixings which enable it to be easily attached to other mountings for a solar array and can be made of recycled plastic by vacuum forming.

Abstract: An extruded polymeric void-board is configured for placement between adjacent horizontal layers of bricks to maintain an opening in a lower layer of the bricks. The void-board is formed as a relatively thin planar element having first and second surfaces. A plurality of parallel ribs extend from and generally transverse to the first side. The ribs have a predetermined height to width ratio and have a height that is less than a thickness of the planar element. The ribs being formed parallel to one another. A method for forming a bundle of bricks with the void-board is also disclosed.

Abstract: A rain gutter cleaning system. The rain gutter cleaning system includes a gutter cleaning chute device having a chute framework defining an opening therein, a chute body attached to the chute framework, and an attachment mechanism for suspending the chute framework and its attached chute body. The chute framework is suspendable by a rod to a ladder or by a hook to the rain gutter. The rain gutter cleaning system can further include a gutter scraper, with a gutter scrapper blade, a handle, and a bracket arm detachably connecting the blade to the handle. The rain gutter cleaning system can further include a straining gutter scooper with straining apertures therein to permit wet debris to be scooped from rain gutters.

Abstract: A system and method for cleaning a gutter for channeling liquid toward a downspout, when the gutter is substantially dry. The system includes an air compressor for in-taking and compressing air to output as compressed air, a hose for channeling the compressed air to the gutter, the hose having a first end and a second end, the first end being connected to the air compressor to receive the compressed air therefrom; and a wand having a first end and a second end, the first end being connected to the second end of the hose for receiving the compressor air from the hose and for directing a flow of the compressed air toward its second end to apply the compressed air to the gutter.

Abstract: The invention relates to methods of treatment of non insulin dependent diabetes mellitus, antagonists of the delayed rectifier potassium channel Kv2.1, methods of using and preparing the antagonists and assays for identifying such antagonists.

Abstract: Within wafer and wafer-to-wafer uniformity of W layers deposited by CVD, employing N.sub.2 for increased reflectivity, is significantly improved by omitting N.sub.2 during at least a portion of deposition. Embodiments include depositing a W nucleation layer on a TiN layer employing gaseous WF.sub.6 during a nucleation phase, omitting WF.sub.6 during an interposition phase during which substantially no W deposition occurs, depositing a W layer employing gaseous WF.sub.6 during a main deposition phase, flowing N.sub.2 gas at least during the terminal portion of the main deposition phase and omitting N.sub.2 gas during at least a portion of the nucleation phase and/or interposition phase, e.g., omitting N.sub.2 gas during the entire interdeposition phase.

Abstract: The invention provides a computer implemented system comprised of two computer terminals for effectuating bidirectional digital, time synchronized communications between networks operating asynchronously with respect to one another. The system repackages the data field of a message received from a network into a message that further includes time indicia corresponding to a time slot in which the repackaged message is to be transmitted so that it may be received by a second network. The repackaged message then is buffered until it is transmitted in the the appropriate time slot so that it may be detected by the second network. The invention overcomes the problem of effectuating communications between distant networks where the message propagation time and time slot period for receiving messages limits the range of communications.

Abstract: A redundant, dual circuit air conditioning apparatus is provided for communications enclosures which is wall mounted thereon. A conditioned air housing is provided having a blower chamber which contains two air circulation blowers thrusting air into the enclosure and having freely pivotal ducts which operate in mutual cooperation in response to pressure variations between the chamber and the enclosure. Internested evaporator coils of two discrete refrigeration circuits share common fin connections for efficiency and each includes a dual line input performing in conjunction with an expansion valve and a simple Y distribution fitting coupled to those lines which achieves requisite pressure drops at low cost.
