Patent number: 10139018Abstract: A foam duct is provided. Among other applications, it may be used in automotive HVAC systems. The method of making this duct reduces material waste and provides an unexpectedly reliable joint in a duct at a sharp or rounded corner. In place, the airflow further supports the joint. In the method, a first portion of a hollow pre-duct is joined with a second portion of a hollow pre-duct by bending the portions at a cut-out positioned between the portions. The bending is complete when the portions form a mechanical connection, which may be signaled by tactile or audible feedback.Type: GrantFiled: March 16, 2016Date of Patent: November 27, 2018Assignee: UNIQUE FARBICATING INCInventors: Daniel Bianchi, Bradley J.

Patent number: 10126212Abstract: A hose or tube for transporting a gas specimen has an inner envelope, forming a diffusion barrier and containing a plurality of perforation holes, and an outer envelope, forming a diffusion layer and resting on the inner envelope. The object is to develop a hose or tube so as to ensure transport of a gas specimen over as great a distance as possible without substantial weakening of the concentration, and at the same time without impairing the ability of the gas to be detected to diffuse into the hose or tube. For this purpose, the outer envelope contains diffusion-inhibiting sealing zones on its inner surface, which zones overlap the perforation holes in the inner envelope.Type: GrantFiled: April 21, 2016Date of Patent: November 13, 2018Assignee: AREVA GmbHInventor: Walter Knoblach

Patent number: 10107441Abstract: A pipe reinforcement system for reinforcing a pipe connection, pipe section, or length of pipe. The invention is most applicable to pipe sections used in commercial, industrial, or manufacturing processes conveying abrasive materials. The pipe reinforcement system uses several interlocking tiles placed over the pipe section to produce a smooth inner surface. The edges of the tiles overlap each other, producing a leak-resistant skin. A cover which maintains air pressure within the pipe is placed over the tiles, keeping them in place and holding them against the pipe.Type: GrantFiled: April 2, 2015Date of Patent: October 23, 2018Assignee: Progressive Products, Inc.Inventors: Stephen T.

Patent number: 9982829Abstract: An external sleeve arrangement for repairing a defective length of pipe has top and bottom segments for substantially encircling the pipe, where the bottom segment in addition has connector plates welded on either side. When the pipe and sleeve segments are made of a similar material, the sleeve segments are made thicker than the pipe wall, up to three times as thick or more, so that upon heating the sleeve segments for a given time they stretch relative to the pipe. After joining the stretched sleeve segments with the connector plates to form a continuous circumferential sleeve, the sleeve is cooled to provide an enhanced interference fit to reinforce the defective length of pipe. Prior to heating, the sleeve segments are clamped about the pipe using a clamping mechanism employing lugs connected to the segments and screw jacks engaging those lugs to draw the segments tight to the pipe.Type: GrantFiled: March 17, 2016Date of Patent: May 29, 2018Assignee: PETROSLEEVE INCORPORATEDInventors: Robert James Smyth, Darcy Evan Miller, Michael Alvin Miller
