Abstract: A coupling having two coupler halves, a female half a male half is disclosed. Pressure will be applied to either half but not both. The female half employs a balanced seal arrangement. Each elastomeric seal of the female half is supported, by a support seal. One elastomeric seal of the female is supported by a rectangularly shaped (in cross-section) Teflon support seal and the other elastomeric seal is supported by a t-shaped (in cross-section) Nylatron.RTM. support seal. When the female half of the coupling is pressurized, pressure will be applied equally to the seals and to the parts of female half such that the net separation force is minimized. Typically the user will select one half of the coupling disclosed herein for use with pressure applied thereto. However, the user may use both halves of the coupling disclosed herein if so desired.

Abstract: A coupling that is useable on farm implements is disclosed. A metal to metal vent valve is employed in the female half of the coupling which constantly vents the supply port to the vent port when the female half is disconnected or partially disconnected from the male half. Steps in the bore of the female body permit easier disconnection because the ball valve is not depressed thus lowering disconnection faces. When the male half is being coupled with the female half the female half is vented thus making coupling easy.

Abstract: A coupling having male and female halves is disclosed. Typically the female half is under pressure. The female half may be mounted to an implement and when coupled to a male coupling on the tractor. It supplies hydraulic fluid to the driven device. The female half has three valves: a main valve, a relief valve and a sliding sleeve valve. The female half, when coupled, opens the sliding sleeve valve first followed by the opening of the relief valve which is followed by the opening of the main valve. The relief valve is designed to reduce pressure behind the main valve so as to permit easy coupling under pressure when the female half is under pressure. During the uncoupling process, the main valve closes first followed by the closure of the relief valve which is followed by the closure of the sliding sleeve valve. The relief valve is a ball and seats against an elastomeric seal mounted in the back side of the main valve. A push pin having flat edges operates the relief valve.

Abstract: The invention is a coupling which includes male and female portions thereof. The male portion usually has pressure applied to it due to heat build up from the environment. The male portion can be and usually is attached to a farm implement. Left in a field in the sun, pressure builds in the male portion while it is disconnected from the female portion. The female portion of the coupling enables the connection of the male portion without spilling any fluid from either the male or the female portions. This is accomplished by the simultaneous engagement of the body of the male and the male valve with an intermediate member of the female portion and the female valve of the female portion such that the female valve and the intermediate member move together into a sealed relationship with the male components. When the supply side female portion is pressurized by a pump the female valve forces the female and male valves to their open positions and allows flow between the female and male portions of the coupling.

Abstract: A pressure locking dispenser half which securely locks with a receptacle half which comprises a connector, a barrel sleeve, and a moveable adaptor. The connector includes first and second passageways. The first passageway of the connector further includes a first port and the second passageway includes a second port, a first seal and a second seal residing between the connector and the adaptor. The adaptor engages the barrel sleeve. The barrel and adaptor include a vent passageway. A spacer resides between the first and second seals maintaining separation of the first and second seals. The moveable adaptor positions the first and second seals in one of a plurality of positions with respect to the connector. A dispenser valve 12 acts in combination with a retainer, a sliding sleeve, and a locking sleeve to pressure lock the dispenser half and the receptacle half together under certain circumstances. Certain positions of the adaptor allow the venting of the dispenser half and the receptacle half.

Abstract: A clean air fan filter module including a fan shroud, a fan/motor mount, a centrifugal fan, a fan motor, and a HEPA filter, the fan shroud having an air inlet and two inclined ends, the fan/motor mounted below the air inlet on the fan/motor mount, the centrifugal fan blowing air radially towards the fan shroud, the HEPA filter constituting the air outlet.

Abstract: A hydraulic coupler half simple enough for use in miniature couplings is disclosed. Both the relief ports and the main fluid ports are in the pintle. The relief ports are uncovered by a hyperextension of the pintle; the main fluid ports are uncovered by retraction of a sliding sleeve around the pintle. The pintle has a single annular contact point with the coupler body and clearances between the walls so that exact alignment is not necessary for connection. The nipple half is conventional.

Abstract: An improved undersea coupler in which a fluid passage is provided in each coupling half. The opening of each passage proximal to the fluid source is controlled by a poppet valve. A sliding sleeve covers the other port of each passage, distal to the fluid source. These distal ports coincide when the coupler is connected, at which position the sliding sleeves are retracted. Sealing between the distal ports and the environment is accomplished by two metal seals backed up by two secondary elastomeric seals. Because the seal arrangement is balanced, and because of the passage design, the system pressure does not cause a high separation force.

Abstract: A semi-balanced valve utilizing a two stage locking with the movable valve sleeve in the nipple locked to the body of the coupler for physical as well as spring loaded movement between open and closed positions.

Abstract: A gasification process of improved efficiency is disclosed. A dual bed reactor system is used in which carbon-containing feedstock materials are first treated in a gasification reactor to form pyrolysis gases. The pyrolysis gases are then directed into a catalytic reactor for the destruction of residual tars/oils in the gases. Temperatures are maintained within the catalytic reactor at a level sufficient to crack the tars/oils in the gases, while avoiding thermal breakdown of the catalysts. In order to minimize problems associated with the deposition of carbon-containing materials on the catalysts during cracking, a gaseous oxidizing agent preferably consisting of air, oxygen, steam, and/or mixtures thereof is introduced into the catalytic reactor at a high flow rate in a direction perpendicular to the longitudinal axis of the reactor. This oxidizes any carbon deposits on the catalysts, which would normally cause catalyst deactivation.

Abstract: Coal or other solid carbonaceous material is contacted with an organic solvent containing both hydrogen and a transition metal catalyst in solution to hydrogenate unsaturated bonds within the carbonaceous material. This benefaction step permits subsequent pyrolysis or hydrogenolysis of the carbonaceous fuel to form gaseous and liquid hydrocarbon products of increased yield and quality.
