20100285261 | Resistive Implant Welding of Thermoplastic Materials with Butt Joints - A method for forming butt joints between thermoplastic members by resistive implant welding. A tongue is formed on one member to be joined and a complementary groove is formed in the other member. A resistive implant is placed between the tongue and the groove which are then pressed together by an applied pressure. An electric current is run through the resistive implant to melt a portion of the thermoplastic material of both the tongue and groove, and the melted plastic intermingles through the implant. When the electric current is removed, the plastic cools, forming a weld. | 11-11-2010 |
20110017394 | System and Method for Placing a Resistive Implant for Welding Assemblies of Plastic Components - An implant applicator and method for positioning a resistive implant material on a first plastic component to be used to form a resistive implant weld between that first plastic component and a second plastic component. The resistive implant material is heated and pressed into a targeted surface of the first plastic component to tack the resistive implant into place. The second plastic component is positioned over the tacked resistive implant and a weld formed in a known manner. The resistive implant material can be heated for tacking by passing an electric current through it before it is pressed into the first plastic component by a second member or by contacting the resistive implant material against a separately heated surface prior to pressing it into the first plastic component. | 01-27-2011 |
20110212331 | Resistive implant welding for adhesive curing for thermoplastic and thermoset applications - A welded joint for structural component having two or more portions fused together at a weld line. An adhesive layer is placed between the two or more portions at the location of the weld line and a conductor is placed between the two or more portions in operable contact with the adhesive. Energy is transmitted through the conductor and into the adhesive layer to activate the adhesive layer and create the weld line that defines the welded joints between the two or more portions. The welded joint of the structural component allows energy to be injected into the adhesive layer via the conductor in order to cause the adhesive layer to activate from the inside of the adhesive outward. The conductor can be placed adjacent the adhesive layer or within the adhesive layer in order to cause the adhesive to be activated from the inside outward. | 09-01-2011 |
20110259248 | SHIPPING PALLET POST REINFORCEMENT - A shipping pallet having a top deck, a bottom skid, and a plurality of posts disposed between and separating the top deck and the bottom skid such that at least one tow fork is able to be positioned between the top deck and the bottom skid. The shipping pallet also includes a plurality of collars formed as part of the top deck, and the posts are integrally formed as part of the bottom skid. Each of the plurality of posts is received into and connected to a respective one of the plurality of collars. There is also a plurality of reinforcements, and each of the reinforcements is disposed within and surrounded by a post. Each post and reinforcement is received into one of the collars, and the post is connected to the collar through a connection point, such as an adhesive joint or thermoplastic weld. | 10-27-2011 |
20110316306 | Water Assist Injection Moulded Structural Members - A method of forming members of fiber reinforced thermoplastic members via molding, the members including at least one hollow chamber, formed by water injection into the melt in the mold, to stiffen the finished member. The thermoplastic is preferably selected from a group comprising polypropylene, Nylon, PET, ABS, TPO, and thermoplastic polyurethane, while the reinforcing fibers are preferably selected from a group comprising glass, aramid, carbon, and natural fibers. Preferably, the extruded melt is produced such that the average length of the reinforcing fibers is less than four millimeters. | 12-29-2011 |
20130068143 | SHIPPING PALLET POST REINFORCEMENT - A pallet used for stowing and transporting items for shipping. The pallet design of the present invention includes a top deck, a bottom skid, and several posts for providing support between the top deck and bottom skid. The posts are integrated with either the top deck or bottom skid. Within each pallet post is a steel tube reinforcement that is overmolded directly into the bottom skid, or is assembled after the pallet post is molded. The supports, which are typically hollow posts, are molded onto either the top deck or bottom skid, and a thermoplastic weld or adhesive joint is applied to the posts to complete the assembly. The palled having the integrated posts and reinforcements provides an economical approach of reinforcing pallet posts to absorb tow fork impact. | 03-21-2013 |
