Abstract: A process for isomerising a (hydrohalo)fluoroalkene, the process comprising contacting the (hydrohalo)fluoroalkene with a catalyst a catalyst which is a chromia-containing catalyst supported on AlF3 or fluorinated alumina.

Abstract: One way to improve fuel efficiency of a vehicle is to improve the usage of various gears. One way to measure the amount of fuel wasted due to suboptimal gear shifting is to compare the actual gear used for various driving conditions with the optimal gear used. Such comparisons may be combined with determinations of amount of fuel used to determine how much fuel has been lost due to suboptimal shifting. These techniques are applicable to tracking employment of other driving best practices as well.

Abstract: A pole apparatus for supporting and operating the push button of a spray can. The apparatus includes an elongated pole having a base end and a top end, a body member mounted at the top end of the pole, means for supporting the spray can from the body member, an actuation slide supported by the body member and including an actuation tab for engagement with the push button of the spray can, a biasing member for biasing the actuation slide to an un-actuated position and a cord that extends between the base and top ends of the pole for operating the slide member. The cord is operable by manually engaging the cord and moving the cord orthogonal to the longitudinal axis of the pole to move the slide member so that the actuation tab operates the spray can push button.

Abstract: A modular lighting fixture may include a housing having opposite ends, an endplate for fastening to one end of the housing, the endplate having a lens receiving face on a first side and an additional-structure-connecting face on a second side. The second side has an outer perimeter portion and a first peripheral surface, the first peripheral surface being inward of the outer perimeter portion. An additional structure is provided having a second peripheral surface with substantially similar contour as the first peripheral surface on the second side of the endplate. The additional structure is connected to the endplate with the second peripheral surface being proximate to the first peripheral surface of the second side of the endplate.

Abstract: A modular, linear-type lighting fixture may include an elongate housing having lengthwise ends, and a pair of endplates adapted for sealing attachment to either lengthwise end of the housing, each of the endplates having respective perimeter surfaces adapted for attachment to any one of a bridge adapted for angularly-directable extension of the housing, a bridge adapted for linear extension of the housing, and an endcap. A modular lighting fixture may include first and second elongate housings each having ends, pairs of endplates for being respectively mated with the first and second ends of the first and second elongate housings, the endplates each having a rim, and a bridge adapted for joining one of the endplates of the first elongate housing with one of the endplates of the second elongate housing by sealing cooperation with the respective rims thereof. A lighting fixture may have one or more isolated raceways therein.

Abstract: A process for removing a (hydro)haloalkene impurity from a product stream containing that impurity and a desired compound is described. The process comprises contacting the product stream with a solid adsorbent comprising pores having openings which have a size across their largest dimension in the range of from about 7 ? to about 10 ?. The process is particularly suited to the removal of (hydro)halopropene impurities from saturated hydrofluorocarbons such as a tetrafluoroethane, a pentafluoropropane, a hexafluoropropane or a heptafluoropropane.

Abstract: A lighting fixture includes a lens frame having a rearmost rear-facing side with an outer perimeter, a baseplate connected to the lens frame, and a water shunt provided at the rearmost rear-facing side near the outer perimeter of the lens frame, the water shunt being structured for restricting water flow directed inwardly of the outer perimeter of the lens frame. A method includes providing a lens frame having a rearmost rear-facing side with an outer perimeter, providing a baseplate connected to the lens frame, and providing a water shunt provided at the rearmost rear-facing side near the outer perimeter of the lens frame, the water shunt being structured for restricting water flow directed inwardly of the outer perimeter of the lens frame.
