Patent number: 6070559Abstract: An annular tube heat exchanger immersed in a medium, such as a fluid. The heat exchanger comprises a fluid-tight combustion tube including a gas-fired radiant burner for providing a source of heat, at least one heat exchange tube including an inner tube disposed within an outer tube, the outer tube in thermal contact with the combustion tube, the inner tube being open-ended to allow the fluid to pass therethrough, and a fluid-tight combustion tube in thermal contact with the outer tube of the at least one heat exchange tube. The combustion gas from the radiant burner passes through the outer tube of the at least one heat exchange tube to cause an increase in the temperature of the fluid. By providing the maximum amount of heat transfer surface area, the annular tube heat exchanger provides a highly efficient means of increasing the temperature of the fluid.Type: GrantFiled: May 21, 1999Date of Patent: June 6, 2000Assignee: Armstrong International, Inc.Inventors: Ronald D.

Patent number: 5056759Abstract: A valve apparatus comprises a valve body having a fluid passage therein including a valve seat. A valve member, having a head and stem, is movable in the body between valve open and valve closed positions determined by the proximity of its head to the valve seat. The valve member is engageable in sealing relation with a portion of the valve body between the valve seat and a valve stem packing to block fluid in the passage from contacting and leaking between the valve stem and packing. This sealing relation also serves to protect a bellows, connected between the valve member and valve body, from contact with fluid in the fluid passage.Type: GrantFiled: September 12, 1990Date of Patent: October 15, 1991Assignee: Armstrong International, Inc.Inventor: Ronald D.

Patent number: 4468962Abstract: An energy loss detecting apparatus for measuring the rate of flow of the vapor phase of a bi-phase fluid flow, in the presence of an unknown quantity of the liquid phase, by separating the vapor phase from the liquid phase and producing a signal representing the vapor phase flow rate. The apparatus includes a hollow separator casing provided with a tube communicating with at least one of the inlet opening and outlet opening of the casing and facing thereinto. A wall seals the interior of the tube from the interior of the casing except at reduced diameter holes in the wall, the diameter of the holes being less than the inside diameter of the tubes at the wall. Energy loss due to a faulty steam trap is measurable by interposing the vapor flow rate measuring apparatus in a steam line between a steam consuming device and the steam trap.Type: GrantFiled: March 5, 1982Date of Patent: September 4, 1984Assignee: Armstrong International, Inc.Inventors: David A.

Patent number: 4456173Abstract: An energy loss detection system includes an apparatus (22) for measuring loss of the vapor phase of a bi-phase fluid. Such apparatus is interposable in an energy transfer circuit downstream of an energy consumer device (14), intended to take energy from the bi-phase fluid by converting the vapor phase to liquid, and upstream of a potential energy loss device (20). The apparatus includes a separator (24) for separating the vapor and liquid phases of the bi-phase fluid into separate flow paths. A probe (51) senses the flow rate of the vapor phase through the separator and produces a signal related thereto. An output apparatus (72) includes a readout device (79) responsive to the probe signal for producing a display indicative of vapor flow rate and hence of energy loss downstream of the separator.Type: GrantFiled: September 2, 1981Date of Patent: June 26, 1984Assignee: Armstrong International, Inc.Inventors: David W.
