Abstract: Methods are set forth for fabricating a concrete panel with embedded glass block. According to the invention the panel form includes at least one partially anchorable support form, i.e., a support form having an anchorable portion and a removable, nonanchorable portion. After concrete is poured into the panel form and hardened, the nonanchorable portion of the support form is removed. A noncementitious band (or collar), of which the anchored portion of the support form is comprised, remains. The glass block is then inserted within this band. According to the preferred embodiment of the invention a rubber seal may be inserted between the glass and noncementitious surface to both waterproof the panel and cushion the block to improve the completed panel's ability to be handled and transported without damage. Furthermore, the invention teaches utilizing the support form to create at least one support lip. Each lip may be formed as part of the anchored band or as part of the formed concrete panel.

The jig then positions the seal, which is partially compressed between the outer plate and an inner plate, within the door opening. The gripping fingers are then released and the arm ends move outwardly so as to press the gripping section of the sealing strip onto the flange.

Abstract: A tool for installing a corrosion barrier ring into its groove behind the threads of a tapered box end comprises a tapered metallic liner for covering the threads and a suitable mandrel for carrying the ring to its location through the liner. A suitable seating tool may be used for the final seating of the ring in the groove. The tip is notched to permit axial deformation of the ring, but not appreciable radial deformation, so as to allow the ring to be positioned to the location of the groove. The tip of the mandrel is sized to prevent the ring from sliding over the mandrel as the mandrel is pushed through the liner. Rotating the mandrel starts the ring into the groove by straightening out the ring deformations and permits removal of the mandrel and the liner. The seating tool is then subsequently used for the final seating of the ring in its groove. Stacked tip pieces permit adjusting the contour and size of the seating tool tip to accommodate to a variety of ring shapes and sizes.
