Abstract: A process is provided for making a fluoroplastic molded-in insert without any supplementary production steps. A predetermined number of polytetrafluoroethylene bearers support a core material apart from the surface of a mold by a space equal to the desired thickness of a surfacing material to be formed on the surface of the core material. After disposing the bearers between a mold surface and the core material, hot-melt fluoroplastics are molded so as to combine the core material, the bearers and the hot-melt fluoroplastics into one unit. As a result, the core material is completely and simultaneously embedded when hot-melt fluoroplastics are molded.

Abstract: A new and unique method of forming and pouring concrete walls is described wherein concrete walls are constructed with unprecedented speed, precision, and flexibility. This is accomplished through the use of preformed corner or angle units working in conjunction with unique forming panels. With the speed of assembly of the forming units a "form and pour as you go" method is utilized which allows the entire structure to be finished in one monolithic pouring of concrete. The method is adaptable to the construction of large or small structures. The method may be used for homes, commercial buildings, public buildings, and for other shelters. The walls so produced may be intrinsically insulated at the time of construction. Cost savings are considerable through the reduction of the amount of labor required and through the use of ordinary building materials that are readily available. The unique more expensive forming equipment can be reused many times and the cost per use would be negligible.

Abstract: An apparatus or clip is disclosed, which can be used both to securely hold and support a heating cable or mat at a desired depth within a slab form, and to easily locate the cable or mats once embedded using a simple magnetic field.

As a stud finder is passed over the clip, the magnetic needle is attracted to the clip apparatus by the emitted magnetic flux. The configuration of the clip includes two upright legs and two horizontal feet. The legs are bent to support and space the mat or cable above the feet.
