摘要： A combustion device which includes a forward section in which a baffle has been inserted for stalling the air and fuel mixture as it passes through the torch tip, generating a linear flame. The baffle is designed to include a substantially circular inner portion of wire screen, sintered powdered metal, or ceramic material, surrounded by a solid annular or substantially annular ring. A plurality of ribs extend between the annular ring and the inside of the tube for connecting the annular ring to the tube and for defining a number of outer passages through which air/fuel mixture may pass.

摘要： A fuel gas combustor which utilizes thermal assisted expansion and mixing of the fuel gas and a combustion supporting gas for more complete combustion and greater heat output. A heat transfer device provides thermal feedback from the flame to the gas expansion zone. The invention is especially useful in hand-held torch tips. In a specific embodiment, the heat transfer device include a heat conducting element, at least the intermediate portion of which is rod shaped and sheathed in a non-conducting envelope.

摘要： A quick connect/disconnect coupler having a slidable piston to connect and disconnect to a standard fitting or coupling attached to suitable tubing. The coupling is slidably received by the coupler and locked in place by the piston. In the locked position, the coupling depresses a valve pin in the piston which opens a passageway in the coupler. At the same time, a depressor in the coupler depresses a valve stem in the coupling, thereby allowing bi-directional gas flow to the device being serviced from the service apparatus, or vice versa. A method of charging or discharging refrigeration apparatus with said coupler is also disclosed.

摘要： An apparatus and method for preventing an undesirable release of fluid from a conduit upon disconnection of the conduit. In a specific form of the invention, the apparatus includes a hose having a slide valve located therein adjacent an end of the hose for preventing the escape of liquids or gases, especially refrigerants, to the environment. The slide valve includes a substantially cylindrically shaped nipple having first and second bores extending axially therethrough, the first and second bores being divided and bounded by an integral wall of the nipple. The nipple includes a plurality of ports adjacent the integral wall which provide passages through the nipple to provide fluid communication between the first and second bores. A sleeve member is slidable disposed around the nipple and contains seals for providing a gas-tight and/or liquid-tight interface between the sleeve and the nipple. The sleeve member also includes an annular chamber for selectively providing the aforementioned fluid communication between the bores. A preferred embodiment of the invention includes a conduit having a threaded screw type valve which includes a substantially cylindrically shaped rear nipple emanating from its first end, having a central bore extending therethrough. The rear nipple is exteriorly threaded to a threaded valve body which, when rotated is capable of sealing and unsealing a valve set with a valve fitting for selectively opening and closing a passageway for the flow of liquid an/or gas from the rear nipple to a front nipple. The front nipple is capable of rotating with respect to the rest of the device without breaking its seal and can be removed and interchanged without a substantial loss of fluid.
