Abstract: The rescue system includes a mobile trailer on which are mounted telescoping hydraulic arms and a winch. A net is connected to the winch and passes over a roller mounted at the outer ends of the hydraulic arms which are vertically and horizontally movable to position the net over the body of water. The net hangs downwardly from the roller into the body of water. A ballast is attached at the lower end of the net so that the net is vertically oriented in the water. A rope connected to the lower end of the net and a set of pulleys enable the lower end of the net to be lifted to envelope a person therein. When the person is enveloped in the net, the winch is actuated via an electric motor to reel in the net and lift the net and the person out of the body of water and to a place of safety.

Abstract: The assembly includes a nozzle adapter rotatably mounted via a pair of axles onto a jet nozzle of a personal watercraft. A hinge rotatably connects a rudder and cap onto the nozzle adapter. A torsion spring on the hinge retracts and retains the rudder and cap in a position in which the rudder extends below the nozzle and nozzle adapter thereby positioning the rudder in the water below the watercraft to provide steering capability to the watercraft. The cap covers and blocks the nozzle outlet when the engine is not operative but when the engine is operative the jet stream forces thereof acting against the cap rotate the rudder upwardly so that it extends rearwardly from the watercraft and out of its steering position. The nozzle adapter includes an inner adapter attached to the nozzle and an outer adapter attached to the inner adapter.

Abstract: The device includes a set of rotatable vanes and a set of stationary vanes which are mounted within a cylindrical housing. The set of rotatable vanes are connected to a post located at the axis of the housing and rotate relative to the post in response to the intake or exhaust fluid impinging on the vanes which are angled relative to the direction of flow of the fluid stream. The set of stationary vanes are rigidly secured to the post and also rigidly secured to the housing walls. The set of stationary vanes are positioned adjacent the set of rotatable vanes and are similarly angled relative to the direction of flow of the fluid stream in order to deflect the fluid stream and impart a swirling motion to the fluid stream in order to provide more complete mixing of the air/fuel mixture of the intake fluid stream or scavenging of the exhaust fluid stream. Tabs which extend radially outwardly from the housing ends secure the device within an intake or exhaust passageway.

Abstract: The device includes a pair of flat planar vanes securely mounted within a cylindrical housing. The vanes have a medial slit extending from the center to a longitudinal end of the vane. The vanes are interconnected at the slits so that they are in criss-cross positioning. The vanes are axially angled so that when positioned in an intake air duct the vanes impart a swirling motion to the air entering the engine providing more complete mixing of the air and fuel and when positioned in an exhaust passageway the vanes impart a swirling motion to the exhaust gases exiting the engine providing scavenging of the exhaust gases.

Abstract: A plunger holder includes a base which is cylindrical and has a bottom surface which is generally straight so that the holder to enable stable positioning thereof on a floor surface. The base has an upwardly curved convex floor and cylindrically shaped outer walls which surround the lower end of the plunger when the plunger is installed in the holder. The holder includes an upwardly curved convex floor to generally securely retain the suction head of the plunger when inserted in the holder and placed on the base. The holder also includes a main body portion which is mounted on top of the base. The main body is generally bottle shaped to conform to the shape of the suction head of the plunger. The main body also includes a pair of shells connected to the base by means of a spiral interconnect.

Abstract: The system integrates an optical signal transmitter, an optical signal detector and a fiber optic cable plug connector into a unitary electronic device assembly. The electronic device, the transmitter and the detector are embedded in a substrate. The system uses an optical alignment subsystem to align the fiber optic cable connector to the substrate so that the fiber optic cable terminus is also aligned to the transmitter and detector (which are connected to the electronic device for data transfer therebetween) when the fiber optic cable is connected to the plug connector. The alignment subsystem includes a laser which backlights a hologram embedded in the transparent substrate producing an image.

Abstract: The device is utilized to provide swirling of either intake air flow or exhaust gas flow of an internal combustion engine. When used to swirl intake fluid flow, the device is positioned in the intake passageway for air entering the carburetor or fuel injection subsystem. The swirling of the air provides more complete mixing of the air and fuel entering the combustion chamber of the engine thereby providing more complete combustion of the fuel mixture. When utilized to swirl exhaust fluid flow, the device is positioned in the exhaust passageway for exhaust gases exiting the exhaust manifold. The swirling of the exhaust gases minimizes slowing of exhaust gas flow through the exhaust system to reduce back pressure and thereby provide more complete combustion. The device includes a set of flat planar vanes which are mounted within a housing. The varies are angled to impart a swirling motion to the intake air or exhaust gas passing through the housing.

Abstract: The system provides a means for identifying the opposite ends of each particular conduit of an array of conduits laidout in a building. The system includes a sonic transmitter and a sonic receiver which are units that are separate from each other and portable. The transmitter is connected to a sonic output transducer mounted on a wand which semi-rigid allowing it to be placed at an open end of a conduit and emit a sonic signal thereinto and through the conduit. The receiver is connected to sonic input transducer mounted on another wand which is semi-rigid allowing it to be placed at the opposite open end of the conduit and receive the sonic signal transmitted through the conduit. The sonic transducers may be moved from one of the open ends to another in the array until the input transducer receives the transmitted signal.

Abstract: A socket designed for manually siding onto a valve adapted for use in a pipe line and enabling rotational movement of the valve and thereby connection to and disconnection from the pipe line. The socket has a square drive bore at a longitudinal end thereof to enable a square drive of a wrench to be inserted therein for rotation thereof. The recess of the socket is open box shaped and dimensioned to fit snugly around the outer surfaces of the valve for snug engagement of the valve to provide rotation of the valve via rotation of the socket. The socket also has semicircular openings at opposing lateral portions thereof to receive control and mounting structures of a ball valve structure therein and fit snugly therearound to provide more positive engagement of the valve. The inner walls of the socket are flat to fit snugly against corresponding flat surfaces of the valve to provide more positive engagement of the valve.

Abstract: An improved spreader bar for spreading apart the cords which connect the body supporting member of a hammock to a support structure and suspend it therefrom is disclosed. The spreader bar is positioned adjacent each of the longitudinal end portions of the body supporting member and is provided with spaced apertures which receive the cords therein. The spreader bar is curved outwardly relative to the body supporting member in order to evenly distribute the suspension forces exerted on the aperture walls by the cords. The spreader bar is also split proximal to or at the apertures into upper and lower members to provide access to the apertures through top portions thereof when the upper and lower members are separated and thereby facilitate insertion of the cords therein when the upper and lower members are separated.
