Abstract: Embodiments of the invention are directed to the preparation of a discrete cyclosiloxane or a discrete mixture of cyclosiloxanes where a dihydroxysilane or dihydroxysiloxane condenses with a dihydrosilane or dihydroxysiloxane in the presence of a Lewis acid catalyst in a reaction phase including a solvent. The introduction of the dihydroxysilane or dihydroxysiloxane and dihydrosilane or dihydroxysiloxane is controlled such that the cyclocondensation occurs in a reaction phase that is dilute in the SiH and SiOH functionality permitting the isolation of the monocyclocondensation adduct in high yield with little higher molecular weight condensation products. In one embodiment of the invention 1,1-diphenyl-3,3,5,5-tetramethylcyclotrisiloxane is prepared in very high yield.

Abstract: The invention is directed to a fishing vessel and a method of menhaden fishing. The fishing vessel comprises catamaran or multi-hulled type boat or ship used as a purse boat. The fishing vessel is outfitted with a jet propulsion drive system and also has various equipment necessary for handling the purse seine, such as with an articulated crane necessary to manipulate the seine or fishing net and partially lift it out of the water, a purse winch, and a tom winch. The fishing vessel can be transported by a steamer boat and once in the fishing area is launched or it can be navigated to the fishing grounds. Once the fish are caught, the fish are unloaded from the seine or fishing net using a vacuum transfer device and stored in a refrigerated storage area on the steamer.

Abstract: A gate valve for a component which includes an elongated body and a flow passage extending generally longitudinally through the body, the flow passage including a generally lateral first branch connected to a generally longitudinal second branch. The gate valve comprises a gate which is moveable generally longitudinally across the first branch between an open position in which a hole in the gate is aligned with the first branch and a closed position in which the hole is offset from the first branch; a conduit which extends through the body from the gate; an actuating mechanism positioned in the conduit for moving the gate from a first position to a second position; and a return biasing mechanism for moving the gate from the second position to the first position; wherein one of the first and second positions corresponds to the open position of the gate and the other position corresponds to the closed position of the gate; and wherein the conduit extends generally longitudinally through the body.
