  • Patent number: 7543855
    Abstract: A hose coupling includes two coupling halves which take a coupling end position by relative rotation against each other about a coupling path of no more than 180°. The hose coupling further includes a locking mechanism that prevents an unintended opening of the coupling. The locking mechanism comprises a latching mechanism, in particular a latching pin mechanism. The latching mechanism is automatically activated in the coupling end position and prevents a relative rotation of the coupling halves against each other. The latching mechanism is preferably configured such that, already before reaching the coupling end position, the latching mechanism is activated so far that it counteracts a relative rotation of the coupling halves in an opening direction.

The first tubular member includes a receiving end portion which receives an insert end portion of the second tubular member. An arrangement of flanges on the respective end portions of the tubular members defines cooperating grooves which receive a C-shaped retaining ring. When two hoses connected by the fitting are twisted relative to each other, the twisted hoses can be straightened by relative rotation of the first and second tubular members, thereby permitting smooth flow of fluid through the fitting.

  • Patent number: 5609298
    Abstract: A magnetically-attached exhaust nozzle assembly for use as part of an exhaust extraction system for a fire truck includes an annular nozzle locator ring which is designed to slide over and secure to the exhaust pipe of the fire truck. The nozzle locator ring includes an inner sleeve which fits closely against the outside diameter of the exhaust pipe and an outer sleeve which receives a flexible exhaust nozzle. The exhaust nozzle is integrally connected with a flexible hose of the extraction system and establishes sealing engagement at two locations on the nozzle locator ring. There is axial sealing by abutment up against a flange of the nozzle locator ring and circumferential or radial sealing due to the fit of the nozzle on the outside surface of the outer sleeve. The flexible exhaust nozzle includes a guide rail which helps with the initial alignment and a magnet housing which ultimately attaches by magnetic attraction to the surface of the exhaust pipe for securely holding the nozzle in position.

  • Patent number: 5597184
    Abstract: A clamp for quick release of a generally rectangular bonnet to the flange of valve body is disclosed. The upper side of the edge of the rectangular bonnet is formed with a bevel of about 20 degrees and the lower side of the edge of the body flange is formed with a similar bevel. The clamp consists of semi-circular ends and straight sides hinged together. One side is split and connected by a toggle latch. In cross-section, each clamp section is generally C-shaped, with the top and bottom arms of the C being beveled so that as the clamp sections are drawn inward the bevels wedge the bonnet against the flange. Locating pins fitting into holes in the plate and flange locate the parts and resist implosion when the valve body is subjected to vacuum. To maintain uniform clamping force around the circumference of the bonnet the bevels at the middles of the sides may be less wide than at the ends.

  • Patent number: 5419354
    Abstract: Methods and apparatus for controlling a fluid passage provide at least one sliding gate movable transversely to that fluid passage. The fluid passage or the gate is maintained open in a first position of the gate, and is closed in a second position of that gate. A detent detains the gate in one of its first and second positions against a bias acting continuously on that gate. Upon release from that detent, the gate slides by virtue of its bias to the other of its first and second positions. The gate and fluid passage may be incorporated in a frangible connection and the gate may be released from its detent for automatic closure by its bias upon breakage of that frangible connection. Alternatively, the gate may be provided with a slanted surface which abuts another slanted surface around the fluid passage in the first position of the gate.
