The wheel well assembly includes a pressure deck that extends from a right side of the airframe to a left side of the airframe and that forms a portion of a pressure boundary delimiting a pressurized space and a non-pressurized space. A floor-panel support is supported by the pressure deck in the pressurized space. The pressure deck and the floor-panel support form a portion of a flight deck floor of a flight deck of the aircraft. A plurality of transport elements is located between the floor-panel support and the pressure deck. The plurality of transport elements is associated with at least one high-level system of the aircraft.

Abstract: A blow back rudder consisting of a rudder blade, rudder shaft and a plate assembly that is pivotally mounted to the nozzle of a jet nozzle of a personal water craft is spring biased in the steering mode and is positioned out of the water by the impingement force of the jet stream discharging from the nozzle acting on the plate. This provides off throttle steering. The plate is contoured to allow the plate to remain in the jet stream at low thrust and water craft speeds for rudder steering. In another embodiment, these features are contained and the plate is contoured with a concave face and its position relative to the discharge port of the jet nozzle is controlled in order to obtain reversing of the water craft.

Abstract: A convertible top canopy is pivotally attached to the hull of a multiple seat cruiser jet boat by a simple linkage system consisting of three U-shaped links each of which are attached at the base of the "U" to the canopy, the main link is pivotally and removably attached to the hull and another link is pivotally attached to the main link and the third link is pivotally attached to the second link and pivots to fold and lie against the deck on the stern of the watercraft. Tension straps at the stern and bow attach to the hull and forward and aft U-shaped links to position the canopy relative to the hull in the up position. The canopy is removable from the watercraft by releasing the main link and straps and usable as a cabana or umbrella on the ground by inserting a portion of the main link into the ground and tensioning the forward straps to stakes mounted in the ground.

Abstract: A chemical pulp which contains reactants capable of generating dioxirane within the pulp is produced in a process which comprises mixing a pulp with reactants comprising a carbonyl compound, preferably acetone, and an oxygen donor, preferably monoperoxysulfate, in proportions which produce a water-soluble dioxirane having a molecular diameter of less than 140 angstrom units. Such a pulp bleaching process which employs dioxirane as a bleaching agent is rendered environmentally and economically acceptable by recycling the reactants employed to produce the dioxirane.

Abstract: A non-aerating fluid dispensing nozzle for dispensing fluid into a receiving tank has a vapor control and containment mechanism for vapors formed in the receiving tank. The mechanism has a chamber disposed within the housing of the nozzle and a gas passage that has a first end connected to the chamber and a second end connected to an intake aperture disposed near the distal end of the discharge nozzle. A pump is disposed in fluid flow communication with the chamber for pumping gases from the fluid receiving tank into the chamber through the gas passage during fluid flow through the nozzle.

Abstract: Two-thirds to five-sixths basic aluminum chlorides having enhanced antiperspirant efficacy are produced by heating an aqueous solution containing about 40 to about 50 weight percent of the basic aluminum chloride to a temperature of at least about 130 degrees C. for about one to twelve hours in a closed vessel, with the heating time being inversely proportional to the temperature. Five-sixths basic aluminum chlorides treated in this manner are characterized by a size exclusion chromatogram having a single major peak with its apex at a relative retention time of about 0.75-0.79. The basic aluminum chlorides may be incorporated into any of the conventional antiperspirant forms with non-toxic, dermatologically acceptable carriers.

Abstract: The subject invention relates to a method of synthesizing nitroxides from secondary amines. This method uses a suitable dioxirane compound such as dimethyldioxirane (DMD), which is relatively stable and simple to synthesize, as the oxidizing agent. A quantity of a secondary amine having no hydrogen atoms directly attached to the alpha carbon atoms is mixed with a 2x molar ratio of the dioxirane. In a first reaction, the secondary amine is oxidized to form a hydroxylamine; in a second reaction, the hydroxylamine is further oxidized to form a nitroxide. When the dioxirane loses an oxygen atom it converts into a ketone; for example, dimethyldioxirane is converted into acetone. This is very convenient, since the ketone byproduct is a solvent that can be easily removed after the reaction without causing interfering reactions. This method provides a simple, highly selective, rapid reaction with very high yields.

Abstract: The subject invention relates to a method of synthesizing hydroxylamines from secondary amines. This method uses a dioxirane compound such as dimethyldioxirane (DMD, which is relatively stable and simple to synthesize), as the oxidizing agent. The reaction proceeds as follows: ##STR1## This method provides a simple, one-step reaction with high yields. It can be performed in acetone solution, and the transferral of an oxygen atom from dimethyldioxirane to the secondary amine converts the dioxirane into acetone, the solvent, permitting simple workup and purification. This method can be used with a wide variety of secondary amines, including aliphatic, aromatic, cyclic, and heterocyclic secondary amines, to create a corresponding variety of hydroxylamines.

Abstract: A decoration for a tree, in particular a Christmas tree is provided, which comprises a shaft having a lower end adapted to attach to the top of the tree, and one or more garlands attached to the shaft and reversibly windable adjacent to it. Preferably, the garlands are attached to respective pulleys mounted about the shaft, such mounting preferably being fixed with respect to the shaft.

Abstract: A tree decoration is disclosed which comprises a storage device which has a plurality of storage units. Each of the storage units has a pulley independently rotatably mounted on the shaft, a rigid support member fixedly connected to the shaft and extending transversely outward therefrom adjacent an outside first end of the pulley, a grip, and a resilient polymer segment. The grip is connected to one of the support member and the outside first end surface of the pulley adjacent the other one. The resilient polymer segment is connected to the other one of the support member and the outside first end surface of the pulley, and is dimensioned so as to normally engage against the grip when aligned therewith and cause the pulley to rotate when the shaft is rotated, and to disengage from against the grip in response to a torque applied to one of the shaft and the pulley when the other one is held stationary so that one can rotate while the other is held stationary.
