20080298788 | Heated hose apparatus and method - A heated hose assembly includes: an extruded inner liner; an intermediate layer comprising strands of a nonmetallic material and at least one heating wire each of the nonmetallic material and heating wire interwoven about the exterior of the extruded inner liner; an outer coating dispersed throughout the strands of the intermediate layer, and; a crimp attachment component for attaching the at least one heating wire to a power source. | 12-04-2008 |
20110299839 | No-freeze water hose - A heatable hose assembly for keeping a liquid above freezing in below freezing ambient temperatures is provided. The heatable hose assembly comprises a flexible liquid transport hose, a thimble apparatus, and an electrical heating apparatus. The electrical heating apparatus is located partially within the flexible liquid transport hose. The heatable hose assembly provides a means for slideably adjusting the electrical heating apparatus within the flexible liquid transport hose. | 12-08-2011 |
20130022340 | APPARATUS FOR DELIVERING A MEDIUM AT AN ADJUSTABLE TEMPERATURE - An apparatus for delivering a medium at an adjustable temperature, comprising a pump, a hose having one end connected to the pump, and the other end for delivering the medium, a heating element provided along a portion of the hose such that the medium flowing through the hose is heated, wherein a thermal resistance is present between the heating element and the medium, and a circuit for adjusting the temperature of the heating element. A resistance detection device connected to the heating element detects the resistance of the heating element. A power detection device connected to the heating element detects the power supplied to the heating element, and a control device establishes the temperature of the medium on the basis of the values established by the resistance detection device and the power detection device, and adjusts the temperature of the heating element according to said established temperature of the medium. | 01-24-2013 |
20130114945 | Plastic Tubular Connecting Sleeve for a Pipe with Internal Liner - pipe having at least two steel pipe elements with internal lining that are assembled together end to end, with the ends of the two pipe elements being welded together. A tubular junction sleeve is interposed inside the pipe at the abutting ends of the two pipe elements so that the end terminal portions of the sleeve are at least in part in leaktight contact with respective ones of the terminal portions at the ends of the internal linings of the two pipe elements. The leaktight contact zone is a zone of fusion welding together the materials in mutual contact constituting at least a portion of each terminal portion of the sleeve and of each respective terminal portion of the lining. At each of the terminal portions of the sleeve in the leaktight contact zone, the tubular junction sleeve presents a Joule effect heater wire arranged in a double spiral on the outer surface of each terminal portion at the ends of the sleeve. | 05-09-2013 |
20140193143 | HEATED HOSE ASSEMBLY - A heated hose assembly may include a flexible hose defining an internal water channel and having first and second ends, a first coupling secured to the first end of the flexible hose, a second coupling secured to the second end of the flexible hose, a hose heating element configured to heat the flexible hose, a first coupling heating element secured to at least a portion of the first coupling and configured to heat the first coupling, and a second coupling heating element secured to at least a portion of the second coupling and configured to heat the second coupling. | 07-10-2014 |
20150016811 | CIRCULATION HEATER - A circulation heater is provided which uses a cast body, having resistance heating elements therein and also having spirally wound Teflon tubing wrapped about the heater body. The heater body is formed of cast aluminum or other suitable cast material and after casting is machined to form at least one spiral channel for receiving the heater tube therein. The heater tube is pressed into the tubing channel as the heater tube is progressively wound spirally about the heater body. The channel is formed with an undercut profile wherein the channel is undercut to form a narrower mouth which allows the heater tube to be compressed and then snapped into the channel. The profile of this channel insures direct contact between the tubing and the channel wall over greater than 180 degrees or more than one half of the tube circumference to increase the area of surface contact between the heater tube and channel surface. | 01-15-2015 |
