Abstract: Disclosed is a wood preservative composition comprising creosote and/or pentachlorophenol (PCP) and one or more unsaturated fatty esters. The composition is useful for reducing insect and microbial decay in wood. Further disclosed are methods of making and using such a composition and wood treated with such a composition.

Abstract: Disclosed is a method of reducing insect and microbial decay in wood. The method comprises the steps of: a) immersing the wood in a treatment solution comprising i) a C1-C6monoalkanolamine ester of boric acid (e.g., monoethanolamine ester of boric acid) and ii) creosote; and b) exposing the immersed wood from step a) to conditions which cause the release of boron from the C1-C6 monoalkanolamine ester of boric acid (monoethanolamine ester of boric acid) and which cause the boron to migrate into the interior of the wood.

Abstract: Provided is a wood treatment composition comprising a reaction product produced by reacting a mixture, which includes creosote and a fatty ester component, in the presence of a Lewis acid catalyst. The reaction mixture may optionally include bunker oil and/or a borate ester. The mixture may comprise i) at least about 85 wt % creosote; and ii) at least about 1 wt % of an ester component containing one or more C8-C50 fatty esters. Also provided are wood treated with the composition and methods for using the composition to treat wood.

Abstract: Disclosed is a wood preservative composition comprising: an ester of boric acid; pentachlorophenol (PCP); and American Wood Preservative Association's (AWPA) P9 Type A solvent. The composition is useful for reducing insect and microbial decay in wood. Further disclosed are methods of making and using such compositions.

Abstract: Material transfer trailers including an elongate chassis, and a longitudinally extending conveyor for transferring material to a desired location, the conveyor being supported by the chassis and including a main portion mounted to the chassis, the main portion having a lower end and an upper end opposite the lower end, an extension portion including a link end moveably mounted to the upper end of the fixed portion and a discharge end opposite the link end, wherein the extension portion is configured to move between an extended position and a stowed position. In some examples, the main portion is fixedly mounted to the chassis. In some examples, the extension portion is pivotally mounted to the main portion. In some examples, the conveyor defines a void to receive a rear-mounted projection of a receiving vehicle.

Abstract: A resilient bumper assembly for a vehicle having an elongate horizontal beam mounted transversely to an end of the vehicle. Exterior flexible sheet cladding mounted on the beam defines an elongate internal chamber between its inner surface and the outer surface of the beam. An elongate resilient impact absorber is mounted to the beam and housed within the internal chamber, with top, bottom, inner and outer surfaces. Vertically extending cavities within the impact absorber, each opening to at least one of the top and bottom surfaces of the impact absorber provide resilient collapsing and rebound of the impact absorber on impact. The absorber may include variations in the size and shape of cavities, thickness of walls between cavities, and variations in the characteristics of material of which it is molded in order to modify the resilient characteristics of the absorber to suit different design needs.

Abstract: A yellow gold alloy which resembles 10 karat gold in appearance and physical properties but has a gold content substantially less than 10 karat gold. The alloy consists essentially of 11% to 16% by weight gold, 28% to 34% by weight silver, 30% to 38% by weight copper, 8% to 12% by weight palladium, 7% to 10% by weight zinc, 0.2% to 0.4% silicon, and about 0.02% boron, and is particularly well suited for use in the manufacture of rings and other jewelry articles.

Abstract: In known air filter assemblies, a mechanism provided for vacuum cleaning of the filter has been located entirely on the upstream side of the filter. In the present filter assembly the vacuum head is mounted on a carriage which is located on the upstream side of the frame which supports the filter and a major portion of the drive mechanism which drives the carriage relative to the filter frame is located on the downstream side of the filter frame. This arrangement serves to reduce the likelihood of contamination of the drive mechanism.

Abstract: A bilge pump switch apparatus for activating and deactivating the bilge pump of the vessel in response to predetermined water levels in the bilge area comprising a housing defining a chamber therein and provided with a fluid port for receiving and discharging bilge water, a mercury tilt switch suspended within the chamber and being responsive to tilting for opening and closing a circuit including a battery, the mercury tilt switch and the bilge pump, and a float responsive to the water level in the chamber for positioning the mercury tilt switch in its normally open position and its normally closed position.

Abstract: The invention relates to the conversion of a substantially conventional gas fired furnace utilizing two or more of the clam shell-type heat exchanger cells, which is modified by converting one cell to a final stage counterflow heat exchanger for the hot gases of combustion, which modification incorporates directing the gases of combustion from the fired cells in a counterflow path through the non-fired cell by utilizing a positive displacement fan and then exhausting the gases of combustion. The modification eliminates the need for positive venting, while substantially increasing the operational efficiency of the furnace unit. The normal flue gas temperature in this type of furnace will be about 450.degree. F., while with the modification, the temperature will be reduced to less than about 200.degree. F. and efficiency will be increased by greater than 10 percent.
