  • Patent number: 9764105
    Abstract: The present invention connects to tubing through which gas flows to a patient. An alert notifies monitoring personnel that oxygen flow to the patient has been interrupted, because the tubing has been disconnected. The invention comprises an adapter that is connected to a gas or oxygen source and a nipple over which the tubing fits and through which oxygen flows to the patient. When the tubing becomes disconnected from the nipple, the oxygen flow actuates an alert. In one embodiment, the invention includes a spring and swing arm that, when the tubing becomes disconnected from the nipple, align the nipple with a swing arm so that the gas flows through the nipple and the swing arm to actuate the alert.

  • Patent number: 4641607
    Abstract: A multistage evaporation boiling equipment is disclosed in the form of a single unit, each stage operating at a different pressure. Two or more bundle type heat exchanger units are horizontally positioned along a central column, part of which units protrude from the column. Attached to the protruding part of each unit is a flange which is covered by a sealing tube wall. A cover over a passageway communicating with this sealing tube wall provides a second seal. One or more walls inside the column separate the heat exchanger units. Openings, which may hold a choke means, are found in the separating wall to control passage of vapor.

  • Patent number: 4550688
    Abstract: Steam outlet connection for connecting the outlet (5) of a tube of the bank of tubes of a steam generator to the pipe (8) connecting it to a steam header. The connection is of the T type with a straight portion (10) closed at one end and a side branch (19) connected to the pipe (8). The closed end of the straight portion (10) has an end wall (14) having a zone of sufficiently slight thickness to permit its perforation for the purpose of injecting a gas into the tube.

  • Patent number: 4494486
    Abstract: A moisture separator is provided which incorporates two perforated plates assembled in association with a plurality of nipples. The nipples extend through a plurality of holes in a first of the two perforated plates. Each nipple is provided with one end which has an upset portion to prevent its complete passage through the holes of the first perforated plate. A second perforated plate is assembled with the first perforated plate in such a way so as to prevent the reverse passage of the nipples in a direction opposite that of assembly. The first and second perforated plates can be rigidly fastened together by bolting, riveting or welding. In a moisture separator made in accordance with the present invention, the individual nipples do not require welding, rolling or hydraulic expansion during the assembly process and do not have to be rigidly attached to either of the two perforated plates. The cooperation of the two plates holds the nipples in position.

  • Patent number: 4175779
    Abstract: A collar for controlling thermal and mechanical stresses and for reducing failures caused by such stresses in gas-transfer tubings, or pigtails, used in a steam reformer. The control collar, in the form of a section of tubing and having the same alloy composition as the pigtail, is placed over each end portion of the pigtail connected to an extension member attached respectively to a catalyst tube in the steam reformer and to a gas-removal manifold. The control collar fits closely over the pigtail and is welded to the extension member. Use of the same alloy composition in the pigtail and in the control collar eliminates stresses associated with differences in thermal expansion and contraction, and the use of the collar reduces mechanical stress fatigue by displacing the point of maximum bending movement from the area of mechanical stress concentration of the weld, and the metallurgical notch in the heat-affected zone of the weld.

  • Patent number: T986007
    Abstract: means are provided for diffusing stresses, particularly in couplings between vertical heater tubes 2 and the connection to a tube (pigtail) 3 leading to a manifold, arising from temperature changes during start-up or shut-down, bending moments and vibration during operation. The stress diffuser may be installed at the connection of the manifold connection such as a "pigtail", to a heater tube and is constituted by a short tube 1 machined to varying inside diameter (preferably constant OD) by tapered wall thickness from a mid-section of maximum wall thickness to lesser wall thickness toward the ends of the stress diffuser. For ease of repair and replacement, the stress diffuser is fitted in a collar 4 on the heater tube.
