Abstract: A process for applying an insulating bonded refractory fiber layer to a substrate such that the bonded refractory fiber will not delaminate form the substrate it is adhered to during thermal cycling. A pre-coat layer of refractory fiber coated with a binder containing potassium silicate, colloidal silica, kaolin clay, hydrated alumina, and optionally, Xanthan gum is applied to a substrate, preferably by spray application. Then a second insulating layer of refractory fiber coated with a binder containing either colloidal alumina, colloidal silica, colloidal zirconia, aluminum phosphates, or mixtures thereof is applied to the pre-coated substrate, preferably by spray application. Finally, the coated layers of bonded refactory fibers are cured. An article comprising a refractory layer bonded to a substrate produced by the foregoing process is also disclosed.

Abstract: Fiber glass insulation batts are packaged by delivering them to the bottom of a stack of batts, then compressing the stack with a compression plate or platen. The compressed stack is pushed by the platen against a web of packaging film and into a hopper. The web adjacent one side of the stack is then moved over the top face of the stack to enclose it, and is heat welded to the web adjacent the other side of the stack. The web is severed intermediate the weld to separate the package from the web, leaving only a single weld in the package. The stack can be compressed by a dished platen to concentrate the greatest platen pressure at the periphery to avoid damaging the major portion of the surface of the batt contacted by the platen.

Abstract: A belt and pulley construction for use in a continuously variable power transmission arrangement. In one embodiment the conical working surfaces of the drive pulleys and the driven pulleys are comprised of removable segments formed of relatively erodable friction modifying material so that the conical pulley surfaces will wear away before the drive belt. In another embodiment the drive belt, whether comprised of a rubber compound or of metal, contains wear faces or pads which contain friction modifying material. Traction between the belt and the pulleys can thus be controlled by members other than solely through the tension of the drive belt.

Abstract: Interlocking end panel flaps of a carton having locking tabs containing diagonal fold lines allowing the wide toe portion of the tabs to fold back when inserting the tabs in locking apertures which are narrower than the width of the toe portion. Holding tabs connected to the aperture edge adjacent the location of the toe portions of the locking tabs extend completely across the width of the aperture in a straight line to better hold the locking tab in place.

Abstract: A refractory binder including a tackifying agent. The tackifying agent is a montmorillonite clay. The binder is a chromium alumina phosphate mixture with a fluxing agent. The binder may also be a colloidal suspension of alumina, silica or zirconia with montmorillonite clay. The binder is used with refractory fiber to produce a monolithic layer.

Abstract: The use of a bifurcated joint to attach a conveniently sized metal flange to a flexible bellows material has been widely used, for example, in the manufacture of a building construction expansion joint cover. The known bifurcated joint is formed by clamping and engaging a marginal edge of the bellows material between opposed folded portions of the metal flashing. It has been found that the attaching force provided by this joint can be enhanced by providing teeth or protrusions in a portion of the metal bifurcated joint. Preferably a punch is used to upset teeth from one surface of the joint, preferably a corrugated portion of the joint, and then bend the thus toothed and corrugated portion into clamping engagement with the marginal edge of the bellows. The toothed hole clampingly engages the bellows material without piercing it and prevents pull out, both prior to curing of the adhesive bond as well as thereafter.

Abstract: A pulley construction for use in a continuously variable power transmission arrangement. The conical working surfaces of the drive pulleys and the driven pulleys are comprised of removable segments formed of material which is relatively erodable so that the conical pulley surfaces will wear away before the drive belt. The segments are to be replaced when their surfaces have been eroded too much. The replacement of the pulley face segments is simpler and less expensive than replacing the belt, and the use of a relatively erodable pulley face prolongs the life of the belt.

Abstract: A non-precious metal drain bushing for use in the start-up of a glass melting furnace. Relatively thin, wide terminal ears extend outwardly and downwardly from the ends of the bushing and are supported against bending stresses by a rigid band or strip which contacts the outer surface of the ears and extends along the bottom wall of the bushing toward the other end for a substantial distance. In addition to the physical reinforcement it provides, the strip also acts to electrically widen the terminal ears.

Abstract: A process is described for the formation of shaped hydrated calcium silicate products. The process comprises reacting an aqueous slurry containing a source of calcium hydroxide, perlite as a source of silica, and a soluble calcium salt in the presence of high pressure saturated steam, then adding cooling water followed by subsequent venting of the reactor vessel to ambient pressure. Reinforcing fibers may then be added after which the desired shapes are molded and dried.
