Abstract: An electronic horn includes a cover (8) on a front side of an intermediate element (6). A first passage (P1) within the horn is defined by a central portion (82) of the cover (8) that projects into a cylindrical interior of a cylindrical water-proofing wall (621). Second passages (P2, P3, P4) extend generally concentrically with respect to the first passage (P1) and are respectively defined by water-proofing walls (83, 84) that are formed on the cover (8) and project into the interior spaces of water-proofing walls (622, 633). The outermost second passage (P4) opens toward the forward direction. The first and second passages (P1-P4) extend in a back-and-forth path that prevents any rainwater, which has entered the interior of the horn through the opening of the outermost second passage (P4), from reaching a resonance space (7) defined between the resonator (7) and a sound-generating oscillator (51).

Abstract: A liquid storage container comprises: a first lid; a container body having an opening on one end, an interior of the container body and the lid forming a chamber. The opening end of the first lid and the opening end of the container body are rotatably and sealingly connected; and a first pipe and a second pipe communicating the chamber with the outside. The first pipe is provided on the first lid. The second pipe is provided on the container body.

Abstract: Cleaning systems and devices are provided for cleaning body-inserted tubes (e.g., endotracheal tubes, chest cleaning tubes). In one embodiment, a closed suction system includes a suction catheter having at least one deployable (e.g., inflatable) cleaning member at a distal portion of the suction catheter and at least one suction opening distal to the cleaning member. The closed suction system module may include a control unit at its proximal end adapted to facilitate operation in one of the following three operational states: i) a first operational state in which only the cleaning member is functional, ii) a second operational state in which only suction is functional, or iii) a third operational state in which neither suction nor the cleaning member is functional.

Abstract: Systems, devices, and methods include a hand-held instrument with an aspiration conduit extending therethrough and with an aspiration needle arranged to aspirate fluid from a surgical site. A vacuum limiter is associated with the aspiration conduit. The vacuum limiter includes an opening formed in a wall of the aspiration conduit, an actuator disposed in the opening, and a biasing element biasing the actuator to a closed position that prevents passage of fluid through the opening. The biasing element is arranged to permit the actuator to displace from the closed position to a relief position so that fluid passes through the opening when a threshold vacuum is reached within the lumen. The actuator can further displace to an override position that prevents passage of fluid through the opening.

Abstract: A video-on-demand system is comprised of a supervisor processor and a co-processor which are intercoupled via a bus. The supervisor processor has a supervisor memory and the co-processor has a co-processor memory. A supervisor control program is in the supervisor memory, which includes—a) a means for transferring a group of video data packets from an externally stored complete video into the supervisor memory, b) a means for building in the supervisor memory, a respective subgroup of internet protocol headers for each video data packet in the group, and c) a means for constructing in the co-processor memory, a transmission control list which indicates how each video data packet in the group and its respective subgroup of internet protocol headers can be accessed from the supervisor memory.

Abstract: A sound producing vehicle exhaust system comprises a housing positionable over an exterior end of a vehicle tailpipe. A turbine has at least one support plate. The support plate is rotatable about a central axis of rotation with the housing and has a plurality of angular blades with interior ends coupled to the support plate for rotation there with. At least one facing disk is positioned within the housing adjacent to the turbine. A central axis is provided through the facing disk and support plate. At least one bearing pin is provided. The bearing pin rotatably couples the support plate to the facing disk. A plurality of apertures extend through the facing disk. In this manner exhaust gasses from a tailpipe will pass through the blades and create a turbine-like sound.

Abstract: The present invention relates to an all-purpose, pneumatic powered signaling device including a first component capable of transmitting signals above water and a second component capable of transmitting a signal beneath the water. The first component includes a pneumatic air horn and the second component a diaphragm and piston. A button actuator is selectively depressed to create a flow passageway from a source of compressed air to the first and second components. A selector switch is selectively adjustable to allow a stream of compressed air flowing through the passageway to enter either the first or the second component and transmit a signal above or below the water.

Abstract: An electro-pneumatic air-horn assembly comprises a horn assembly, an electrically powered air-compressor assembly, a mounting bracket, and a rigid metal conduit. The horn assembly includes an elongated trumpet. The air-compressor assembly is adapted to provide air to the horn assembly. The mounting bracket is adapted to support the air-compressor assembly and the horn assembly and mount the air-horn assembly to a vehicle. The mounting bracket includes an upper portion operatively attached to the air-compressor assembly, a lower portion operatively attached to the horn assembly, and an elbow transition extending between the upper and lower portions. The rigid metal conduit extends between the air-compressor assembly and the horn assembly to provide fluid communication therebetween. The horn assembly, air-compressor assembly, mounting bracket, and conduit are pre-assembled and adapted to be mounted directly to the vehicle as a unit.

Abstract: A suction control valve is disclosed which includes a primary suction device access and an ancillary suction device access. The valve includes an actuator which is movable between a first position in which the primary access is closed against suction pressure therethrough, to a second position in which the primary access is open to suction pressure therethrough, or alternatively, to a third position in which the primary access port remains closed to suction pressure therethrough and the actuator becomes locked against movement into the second position. When the actuator is in the first position, atmospheric air can pass through the valve and into the suction pressure source in such a manner that a "hissing" auditory signal is generated, indicative of the presence of suction pressure within the valve. When the actuator is in the second or third positions, the "hissing" is prevented.

Abstract: A motor vehicle speed-control system includes a bellows chamber having a movable wall connected to the engine throttle. The pressure of the gas in the chamber is controlled by two electromagnetic valves, the first electromagnetic valve being energized with electrical pulses to repetitively connect the bellows chamber alternatively to atmosphere and vacuum, and the second electromagnetic valve being spring-biassed so that, when deenergized, it vents the chamber to atmosphere to ensure rapid closure of the throttle, and when energized, closes the said vent. An auxiliary fail-safe brake-pedal valve is provided. An audible signal is produced by a flow of air in the event of malfunctioning of the actuator device.

Abstract: A whistle audibly responsive to extremely small pressure differentials is described. The whistle has a cylindrical inlet portion, a cylindrical outlet portion and a cylindrical constriction that form a passageway between said inlet and outlet portions. The whistle produces audible sound having an intensity of about 80 DB in response to a pressure differential, across the inlet and outlet portions, that is in the range of about 0.005 to 0.02 psi.
