A rectangular framework is suspended from the support member through an articulated link rod, a ball joint and an articulated component, for instance an articulated parallelogram. Two rigid components of variable length, for instance two jacks, are interposed, the first one between the rectangular framework and the articulated link rod, and the second one between the support member and the articulated component. The length of each rigid component is adjusted in operation so that the lateral sides of the rectangular framework are always parallel to and equidistant from the longitudinal plane of symmetry of the vehicle.

Abstract: A fluid transfer system including a cap member having a first fluid transfer member therein and being removably mountable on a second fluid transfer member. Cooperating lugs and slots formed by the cap member and second member lock the two members together when the cap is placed on the second member and rotated relative thereto. A resilient annular gasket is disposed between the second member and cap member and surrounds the liquid passageway therethrough to prevent leakage. The second member and cap members form an annular space on one side of the outer peripheral portion of the gasket, and an annular bead presses against the other side of the outer peripheral portion of the gasket so that the bead bends that portion of the gasket into the annular space to effect a liquid-tight seal on both sides of the gasket.

Abstract: An aroma-dispensing cartridge and holder assembly attachable to an air vent in the interior of an automobile. When activated, the assembly functions to diffuse an aromatic vapor into the forced air stream emitted through the vent into the interior. The assembly is constituted by a holder provided with an array of parallel slots and a replaceable cartridge which is telescoped therein. The cartridge contains a porous pad impregnated with a liquid scent and includes a like array of slots. The inserted cartridge is axially shiftable relative to the holder from an inactive position in which the holder and cartridge slots are out of registration to effectively seal the pad, to an active position in which the slots lie in registration, as a consequence of which the forced air stream from the vent passes through the porous pad to volatilize the liquid scent.

Abstract: An adaptable material-spreading vehicle includes in combination a truck body frame, a rear-mounted engine on the frame above the rear wheels, a forward cab, a removable hopper positioned between the cab and the rear-mounted engine, and a conveyor running from beneath the hopper directly through the cab to a material spreader mounted forward of the cab in view of the operator, with the hopper and conveyor being removably mounted to the truck frame, such that the material spreader vehicle can be converted to some other use. In one embodiment, the cab is provided with a central channel through the floor to accommodate the section of the conveyor passing through the cab, with the cab being provided with sealable conveyor ports aligned fore and aft through which the cab-carried conveyor section is passed.

Abstract: A flame spray system comprising a torch is provided having a gas mixing chamber and means for feeding acetylene and oxygen to the mixing chamber in a preselected proportion. The system includes acetylene valve means with an orifice restrictor for feeding the gas to a mixing chamber, the orifice size being selected to provide, in the choked state, a flow of acetylene therethrough under a selected choke pressure.

Abstract: An injection valve for fuel injection devices for internal combustion engines which serves to inject fuel into the intake pipe. The injection valve consists of a valve body with a valve seat cooperating with the sealing part of a valve needle. The valve needle is guided by guide sections in a guide bore of the valve body. The guide section immediately adjoining the sealing part simultaneously serves as a metering section for metering the fuel. For this purpose axially extending surfaces are disposed on the metering section, which form throttling metering openings together with the guide bore. By metering the fuel upstream from the valve seat, impairment of the fuel metering because of deposits formed by reaction of harmful materials from the intake pipe is avoided.

Abstract: The invention relates to various improvements to a hand-operated hose for atomizing a liquid, especially for the treatment of plants. A tubular filter is tightened in a tubular handle by a box-nut against a transverse wall mounted in the tubular handle. This transverse wall is integrated with a rigid tube connected to a flexible feed-pipe. After dismantling of the box-nut, the filter is easily accessible for cleaning.

Abstract: An atomizer in which oil is atomized by steam and a hollow conical pattern of oil is emitted for combustion and applicable to boiler firing. Oil and steam flows pass through intersecting passages so that atomization occurs before the oil and steam mixture enters an annular chamber; or the flows intersect at or adjacent entry to the chamber. Further mixing occurs in the chamber from which the mixture is emitted.

Abstract: A mixing and spraying apparatus for liquids, optionally for powder and liquid, comprising two branch lines on a conduit conveying water under pressure. One branch line passes tangentially through the tank wall into the mixing tank and causes the water in the mixing tank to rotate in a vortex to mix with the added liquid or powder that is introduced into the top opening of the tank in batches or continuously by means of suitable equipment for this purpose. The other branch line passes radially into the tank through the lower wall portion of the tank and terminates in a nozzle, which together with an open end of an outlet conduit forms an injection pump for conveying the admixed components from the mixing tank to a spray hose and nozzle that are connected to the outlet conduit.

Abstract: A vacuum/pressure liquid waste application system for vacuum loading a distribution tank with liquid waste treatment materials and distributing the liquid matter via a pressurized tank and flow-forming and directing sludge gun. Clog-free directional surface application is thereby achieved over relatively rugged or inaccessible terrain.

Abstract: A thermal fog generator having an internal combustion engine rotating a blower to discharge a continuous stream of air through a tube into the atmosphere. The hot exhaust gas from the engine is directed to an enclosed muffler and exhaust pipe into the air moving through the tube. A liquid formulation stored in a container is delivered to the muffler. The hot exhaust gas in the muffler atomizes and vaporizes the liquid formulation and carries the atomized and vaporized liquid formulation to the air moving in the tube. The cool air condenses the vaporized liquid formulation to produce a fog. A hand-operated control is used to regulate the supply of engine crankcase gases under pressure derived from the engine crankcase to the container. The control includes a valve unit operable to bypass the crankcase gases under pressure from the engine to the atmosphere and vent the gases under pressure from the container to promptly terminate the flow of liquid formulation to the muffler.

Abstract: Apparatus for introducing a selectably variable flow of water to a steam line so as to reduce the superheat of the steam. The apparatus provides two separate water valve elements for controlling the flow of desuperheating water at relatively low and high volumes of water. These minor and major valve elements are concentric with each other and with the desuperheater housing, and are progressively operated by a single linear operating rod. A whirling motion is imparted to the major and minor water sprays, maximizing the surface area of each water spray and thereby providing more efficient desuperheating.
