Abstract: An electrical junction box cover system includes a waterproof dome-like covering lid allowing the system to be installed near water. The system also includes a manual power switch with a manual actuator installed on the outside of the covering lid and accessible to the user. The switch actuator has three positions, wherein the actuator in the first position turns an external load circuit on, in the second position it turns the external circuit off, and in the third position it enables the remotely controlled operation of the external circuit. A remote control receiver with an electronic control module and an electric power switch are included in the system as an assembly in order to allow a remotely controlled operation of the system.

Abstract: Disclosed is a light appliance and a cooling arrangement, comprising a light appliance and a substantially sealed enclosure for the light appliance that gives off unwanted heat into surrounding air within the enclosure during operation. The enclosure has an external wall at least part of which is thermally conductive. A medium, cooler than the external wall of the enclosure, contacts the external wall. An air circulating device is provided for circulating air, heated by the electrical appliance or by the air circulating device, to the thermally conductive portion of the external wall for removing heat from the air by thermally dissipating the heat into the cooler medium through said thermally conductive portion.

Abstract: A light fixture with a submersible enclosure for an electric lamp (e.g, HID lamp) is disclosed. The fixture includes a ballast for supplying power to a high intensity discharge lamp. A submersible enclosure seals the lamp from water in normal operation. The fixture includes a water-sensitive circuit having a conductance that increases in response to water that leaks into the enclosure for conducting current from the ballast and limiting the ballast voltage. Alternatively, the submersible enclosure may contain a power lead for supplying power to an electrical load such as a lamp ballast, a non-ballasted lamp, or a color wheel. The power lead includes a fuse region that corrosively reacts in the presence of leaked water in the container, so as to sufficiently wither away the fuse region and terminate power to the load. The foregoing alternative versions may advantageously be combined.

Abstract: A continuous process is presented for the production and recovery of a high purity stream of 2,6-dimethylnaphthalene. The process comprises the general steps of: fractionating a hydrocarbon feed stream to recover a process stream rich in the various isomers of dimethylnaphthalene; subjecting the process stream rich in isomers of dimethylnaphthalene to a selective adsorption step to produce at least two streams of dimethylnaphthalene isomers, one lean in the 2,6-dimethylnaphthalene isomer and subjecting the stream of dimethylnaphthalene isomers lean in the 2,6 isomer to isomerization to increase the concentration of the 2,6 isomer of dimethylnaphthalene therein and directing the isomerized stream back to the fractionation zone to further processing.
