Abstract: Nozzles for discharging high velocity air are positioned on either side of an aircraft engine exhaust duct exit. High velocity air is discharged tangential to an outer surface of each nozzle and follows the contour thereof. The nozzles are positioned so that when the high velocity air separates from the outer surface of the respective nozzles, it flows outwardly relative to the aircraft's fuselage structure. The high velocity air from the nozzle closest to the aircraft's fuselage structure impinges on the exhaust gas stream, deflecting the stream away from the fuselage. The high velocity air from the nozzle furthest from the fuselage creates a low pressure area which deflects the exhaust gas stream away from the fuselage. In combination, the two nozzles deflect the exhaust gas stream away from the fuselage to a significant degree.

Abstract: A control system for an absorption heat transfer plant controls the quantity of heat input into the plant's concentrator in response to the plant's evaporator liquid refrigerant temperature. The control system also controls the temperature of the cooling fluid for the plant's absorber and condenser.

Abstract: A ratchet wrench comprises a ratchet head having a conventional ratchet system for rotating a shank about an axis. A generally cylindrically shaped connecting pin aligned along an axis parallel to the shank axis is attached to the ratchet head. The connecting pin extends through a splined orifice in a handle, thereby connecting the handle to the ratchet head. The handle is slidable between a locked position and a unlocked position on the connecting pin. When the handle is in the locked position, the ratchet wrench can be used to rotate a nut or bolt in a conventional manner. When the handle is in the unlocked position, and the ratchet wrench can be used to rapidly rotate a nut or bolt by moving the handle in a reciprocating manner. When a nut or bolt to be rotated is near an obstruction, the handle can be unlocked, rotated about the connecting pin axis, then locked, thereby adjusting the angle between the longitudinal axis of the handle and the longitudinal axis of the ratchet head.

Abstract: As user is allowed alternatives for selecting computer application program actions which are dependent on the position of a computer display cursor. If the cursor is located at the position where the action is desired, the computer's user selects a textual or symbolic description of the action, thereby causing the action to be performed at the cursor's position. If the cursor is not located at the desired position, user moves an icon associated with the desired action to the desired position, thereby moving the cursor and causing the action to be performed at the desired position.

Abstract: A clamp for retaining electrical wires, fluid conduits or the like has restraining means adjacent to the inner ends of the clamp's legs. When the clamp is closed, the hook of a hook-shaped member adjacent to the upper leg passes through a slot adjacent to the lower leg and engages the outer surface of the clamp, thereby retaining the clamp in the closed position.

Abstract: An improved feathering flexure for a helicopter rotor system yoke includes, in transverse cross section, a relatively thin central web and six relatively thin flanges. Three flanges extend from each of the web's two edges, and the flanges lie in planes which are approximately radial relative to the neutral feathering axis of the feathering flexure. The feathering flexure is constructed of fiberglass material embedded in a polymer matrix. The web's fiberglass material in the web is bias material, that is, material whose glass fibers are oriented at plus or minus 45 degrees relative to the yoke's spanwise axis. In transverse cross section, each of the flanges includes two unidirectional belts disposed on either side of a bias pack. The glass fibers in the unidirectional belts are oriented parallel to the yoke's spanwise axis. The fiberglass material in the bias packs is bias material.

Abstract: A control system for an absorption heat transfer plant controls the quantity of heat input into the plant's concentrator in response to the plant's evaporator liquid refrigerant temperature. The control system also controls the temperature of the cooling fluid for the plant's absorber and condenser.

Abstract: A wire crimping machine automatically adjusts the crimping means to the proper crimp depth for a selected size of wire and the size of the contact to be crimped onto the wire. The size of wire to be crimped is selected by the operator. As a wire is inserted into the machine for crimping, an arrangement of light emitting diodes, photo diodes, and associated circuits determine the wire's size and whether the wire is stripped. The crimping means is allowed to actuate only if the wire is stripped and the wire's size is the same as that selected by the operator.

Abstract: An airborne container for a liquid or other flowable material has bottom doors which are opened to release the material on the ground below the aircraft. To maintain a specified coverage level, a control system which includes a digital controller repeatedly calculates a differential pressure across the doors and varies the position of the doors to maintain a constant material flow rate as the differential pressure varies. The control system closes the doors when a specified volume of material has been spread.

Abstract: An improved dispenser for cosmetics has a lid that is secured to the opening of the dispenser's container by at least one lock, thus preventing access to the dispenser's contents by the public. A stopper is utilized to prevent liquids from entering the lock's keyhole.

Abstract: A suspension system for a vehicle wheel set, comprising first suspension means, second suspension means, and stabilizing means arranged generally transversely of the longitudinal axis of an associated vehicle and arranged to act in conjunction with at least one of said first and second suspension means, provide the vehicle with an anti-roll characteristic when operating under certain conditions. In a preferred embodiment, the first suspension means comprises a pair of leaf springs, and the second suspension means comprises a leaf spring, coil spring, hydraulic, pneumatic, or rubber (elastomeric) suspension arrangement, or any combination thereof, connected to an anti-roll bar or tube. Also provided is a composite stabilizing means in the form of an anti-roll bar or tube connected between a pair of leaf spring arms, preferably adjustable longitudinally thereof.

Abstract: A catheter for insertion through a main artery into a branch artery ostium comprises a shaft, an integral profiled portion, and an integral tip portion. The profiled portion comprises a series of bends and straight legs. The tip portion of the catheter axially engages the branch artery. The profiled portion is shaped and dimensioned so that when the tip portion is engaged with the branch artery, the leg of the profiled portion adjacent to the shaft will be parallel to and engaged with the opposing inner wall of the main artery to resist forces tending to displace the tip portion from the branch artery.

Abstract: A magnetic tool for conditioning fluids includes a hollow core providing at least one passage through which the fluid to be treated flows. An array of magnets extends longitudinally along the core with the poles of the magnets arranged to provide a magnetic field perpendicular to the flow path to enhance the magnetic conditioning effect of the tool. The magnets are formed of a rare earth magnetic material, such as neodymium-iron-boron, and are backed by a flux-carrying member of cobalt-iron-alloy, with rounded corners to reduce loss of a magnetic field. Each magnet is mounted at least partially within an outer surface of the core with the flux-carrying member contacting, covering, and extending between the outer major faces of the magnets.

Abstract: A storage unit for CD discs comprises a box-like housing in which is mounted a vertical spaced array of horizontally disposed sleds. The sleds slide in and out of the housing on tracks provided in the housing sidewalls. Conventional CD jewel boxes are retained on the sleds and a rod engaging the underside of the lid of each jewel box passes through the jewel box with its ends engaged in a groove formed in the side walls of the unit. The grooves are configured to move the rod vertically away from the sled as the sled is moved out from the housing. The vertical movement of the rod forces the lid of the CD up, giving the user access to the CD stored in the jewel box.

Abstract: Apparatus for charging storage cylinders with a cryogenic gas comprises a mobile storage tank for the gas in liquid phase, fill and return lines that can be connected between the tank and a valve manifold at a remotelly located site at which the storage cylinders are located. The valve manifold receives incoming liquid gas and diverts some of it to a number of cylinders in which it is stored in liquid form and, after the remainder, after a controlled expansion to gas phase, to a cylinder which converts to a beverage dispensing system at the remote location. The system comprises fill and return lines to avoid venting gas to atmosphere during the filling process.

Abstract: A cover for a swimming pool comprises an awning of flexible waterproof sheet material having guide members secured to its longitudinal edges. A pair of side rails are fixed to the longitudinally-extending walls of the pool.
