  • Patent number: 4899826
    Abstract: A fire extinguisher for automotive use is provided with the additional capability of sealing and reinflating a flat tire without any wheel removal. The device is charged with a combination fire-extinguishing and tire-sealing composition, and fitted with a removable nozzle for extinguishing fires. To seal and inflate a flat tire, the nozzle is removed, and, in its place, one end of an adaptor hose assembly is attached to the fire extinguisher, and the other end is connected to the tire valve with the wheel rotated to place the puncture or leak at the bottom. Then actuating the device dispenses sealant into the tire while inflating it, after which vehicle movement distributes the sealant and generates heat which accelerates the tire-sealing action and further inflates the tire to a higher pressure, enabling the vehicle to proceed to a service station.

  • Patent number: 4889509
    Abstract: On a rowboat with fixed installed rowing seats (4) and outriggers which can move in relation to them in the longitudinal direction of the boat, the outriggers are designed as slideable outriggers (1) which can slide on a single linear guide (11) like sleds, without tipping, forward or backward. In one particular configuration, there are connection devices (17, 18) located between the outboard segments of the sliding outriggers (1). These connection devices can also be located inside the hull of the boat. The linear guidance mechanism (11) consists essentially of a shaft (12) running parallel to the longitudinal axis of the boat inside or outside the hull of the boat (11a). One or more suspension elements (13) connected with one or more sliding outriggers (1) are guided in a sliding or rolling manner on this shaft (12).

  • Patent number: 4887985
    Abstract: A swim fin provided with a canal-like member for conveying and controlling the fluid flow produced during each swimming stroke. The fin comprises at least at the central portion of its blade a section which, by dynamical deformation, gives rise to a canal-like fluid flow conveying member on that side of the fin opposed to the side under active stroke. The canal-like member is inverted as soon as the swimming stroke is reversed, so as to perform its fluid flow conveying action during both swimming strokes.

  • Patent number: 4887654
    Abstract: A floating dock includes a plurality of float modules comprised of containers having opposing walls, a deck with opposing edges mounted in spaced relationship above the float modules, and a pair of wales extending along opposing walls of the float modules and opposing edges of the deck. Compression rods extend between the wales and act on the pair of wales such that the compression rods exert compression force on the float modules and deck. A compression beam or plywood panel extends between the opposing walls of the container below the compression rod to create a box beam in combination with the wales and deck, therefore rigidifying the dock to enhance its portability on land and wave resistance properties in water. The float modules are spaced apart longitudinally of the dock to allow wave transparency and wash space for debris. The space betwen the deck and float modules forms a passageway for utility conduits.

  • Patent number: 4881856
    Abstract: A device for cleaning impacted material, such as wood chips in silos, utilizing a raking action of regularly spaced spikes and a flailing action of a hose with a jet stream nozzle. The device comprises a hose, connectable at a proximal end to a compressed air supply, and a nozzle connectable to a distal end of the hose, the compressed air being forced through the hose and out the nozzle to cause the nozzle and the hose to move under the influence of the expulsion of compressed air at the distal end of the hose. The spikes are attached along the hose to provide regularly spaced raking elements, and anti-kink mechanisms urge the hose into straight alignment. In operation, the nozzle is lowered into a silo in the vicinity of impacted material. Then compressed air is introduced into the hose and expelled out the nozzle in a jet stream thereby causing the hose and nozzle to undulate within the silo such that the spikes strike and dislodge the impacted material.

  • Patent number: 4878785
    Abstract: Abrasive fluid, which includes abrasive material and a carrier fluid, is transported through a conduit with minimum wear by directing the abrasive material along the center of the flow channel within the conduit, accelerating the carrier fluid and entraining the abrasive material within the accelerated carrier fluid. A conduit for performing this method includes a flow channel, means (9) adjacent its upstream section (1) for directing abrasive material along the center of the flow channel, a section (2) of reduced cross-section for accelerating carrier fluid in the flow channel and a down-stream section (3) for accelerating the abrasive material at the center of the flow channel due to entrainment with the accelerated carrier fluid.

  • Patent number: 4834011
    Abstract: There is disclosed an improved stern seal construction for air cushion surted operating type marine vessels which consists of an array of inflatable, vertically oriented inverted truncated open-ended cones or fingers. These fingers are individually attached to and mounted to depend in side-by-side relation from the bottom of an inflatable bag which in turn is mounted upon and extends transversely across and below the bottom of the stern end of the vessel's hull. The fingers are arranged in side-by-side pressed together relationship, and thus assume in horizontal section generally rectangular forms. In side view sectional profile the finger and bag contours are so balanced that a minimum load at the bottom ends of the fingers will permit them to raise to allow for passages over rough objects. The front or leading panels of the fingers are stiffened somewhat toward their bottom ends, and are extended under the open bottoms of the fingers beyond their trailing panel portions.

  • Patent number: 4834188
    Abstract: A fire extinguishing system for a cookstove or range includes a fire extiisher mounted above a hood positioned over the cookstove or range. The fire extinguisher is connected to a pair of nozzles within the hood to dispense fire suppressant over the cookstove or range. The fire extinguisher includes an operator normally biased to the operable position, but held in the inoperable position by a cable having a plurality of fusible links distributed therein. The cable is held in tension adjacent the inner periphery of the hood. Upon the occurrence of a fire, at least one of the links separates, releasing the cable and allowing the operator to move to the operating position whereby the fire extinguisher releases the fire suppressant. A low-voltage control circuit is used to cut off the flow of electricity or gas to the stove and to sound an alarm. A battery is provided with the low-voltage control circuit so that the system will still operate if house current is interrupted.

  • Patent number: 4834589
    Abstract: Apparatus and process for transferring pulverent material from a supply container to a delivery point comprises an elongate exhaust pipe having a first end and a second end with a filter near the second end, an intake pipe extending from the supply container to the first end of the exhaust pipe and a transfer pipe extending from the first end of the exhaust pipe to the delivery point. With the first end of the exhaust pipe connected with the intake pipe, suction is applied to the second end of the exhaust pipe to draw pulverent material from the supply container to and through the intake pipe into the exhaust pipe where it is blocked by the filter. The first end of the exhaust pipe is then connected with the transfer pipe and air under pressure is supplied to the second end of the exhaust pipe to propel the pulverent material from the exhaust pipe to and through the transfer pipe to the delivery point and to clear the filter.
