Abstract: A method of repairing a thermal barrier coating on an article designed for use in a hostile thermal environment, such as turbine, combustor and augmentor components of a gas turbine engine. The method is particularly suited for the repair of thermal barrier coatings composed of a metallic bond layer formed on the surface of the article, and a columnar ceramic layer overlaying the bond layer. The method entails the steps of cleaning the bond layer exposed by localized spallation, treating the bond layer so as to texture its exposed surface, and then depositing a ceramic material on the surface of the bond layer so as to form a ceramic repair layer that completely covers the bond layer. Deposition of the repair layer can be carried out such that its upper surface projects above the adjacent ceramic layer, followed by abrading the repair layer to a height substantially level with the ceramic layer.

Abstract: A process and device are disclosed for producing glass fiber mat reinforced thermoplastic boards, as well as their advantageous use. Glass fiber mats are impregnated with molten thermoplastics and the composite glass fiber mat is then pressed. At least one of the glass fiber mats runs through the aperture of an impregnation nozzle controllably supplied with molten thermoplastics by extruders, forming two streams of molten mass that are applied at the outlet of the nozzle aperture on the top and on the bottom of the glass mats, pre-impregnating the glass fiber mat. These glass fiber mats thus pre-impregnated with thermoplastics runs through a gap between feeding rollers of a double belt press, are pre-calibrated then pressed by cooling plates into glass fiber mat reinforced thermoplastic board.

Abstract: Disclosed is a process for producing a loop material suitable for use on a disposable garment. The process includes the following steps. Forming a woven loop material having a lubricating material thereon. The lubricating material is present on the woven loop material in an amount effective to assist in the formation of the woven loop material. The woven loop material is rinsed with a liquid to form a rinsed loop material. The rinsing process causes the amount of lubricating material on said woven loop material to be reduced. Finally, the rinsed loop material is attached to the disposable garment. A disposable absorbent garment including the rinsed loop material is also described.

This polyurethane foam is characterized by a density of less than 300 g/l, preferably from 20 to 150 g/l, and optionally contains isocyanurate groups. Suitable flexible facings include those having a thickness of less than 10 mm, preferably less than 2 mm. This composite bodies produced by this process are suitable for use in the automobile sector as self-supporting components. Conventional stiffening elements are not necessary to produce these self-supporting composite bodies.

Abstract: A method for securing a pour spout fitment to a thermoplastic-coated container, wherein at least a surface of a pour spout fitment is heated remotely by a suitable heating mechanism, to a predetermined temperature. When the heated fitment surface is applied to a selected surface of an erected, thermoplastic-coated container, the heat energy is transferred to the latter surface to an extent capable of activating the thermoplastic coating thereon. Upon cooling, the fitment and the container surface are bonded together, without the need for a back-up or support mechanism, such as a mandrel or anvil.

Abstract: A method for sealing the open end of two compartment containers which are filled through an opening in the lower terminal end of each compartment. The method consists of placing a steel platen between the compartments at the lower end terminal edges of each compartment so that the terminal edges confront the opposing side faces of the platen. The lower terminal edges are then heated and a pair of dies are activated towards and away from one another to apply pressure to the lower terminal edges to seal the edges against the platen.

Abstract: The diets of ruminant animals include proteins which are, unfortunately, largely degraded in the rumen. Therefore, most of the protein is not available to the animal in the intestine where the nutrients can be properly absorbed and utilized by the animal. The present invention overcomes this problem by providing a composition that can be applied to a feed product in order to protect it from degradation in the rumen. In particular, the composition comprises about 10% w/v zein and from about 1 to about 2% formaldehyde in an aqueous alcohol solution. The invention also includes the method for protecting the feed product as well as the protected feed product.

Abstract: A non-contaminating catheter includes a hollow tube having an axial lumen extending along the length thereof, and an elongated, tubular, flexible membrane disposed within the lumen. The leading end of the membrane is circumferentially folded back over the leading edge of the tube and fixed to a guide assembly. As the catheter is inserted into a patient, the membrane is dram through the tube and out the leading edge of the tube. Once the catheter is fully inserted, the membrane circumscribes the tube; thus, contact between the tube and the patient is substantially, if not entirely, prevented during insertion of the catheter over the length of the membrane. More particularly, the membrane is laid out as the catheter is urged along the anatomical canal and thus remains interposed between the exterior wall of the catheter and the patient's internal organs (e.g., the urethra).

Abstract: A method is provided for producing a thermoplastic resin sheet or film by hot-melting and then cooling a thermoplastic resin to form a sheet or film. The thermoplastic resin sheet or film is moved so that it is pressed against the outer surface of an external heated roll and against a heated, endless metal belt. The endless metal belt is disposed at one end around a moving, internal heating roll and at an opposite end thereof around a moving, internal cooling roll. The internal heating roll heats the endless metal belt to a temperature higher than the softening point of the thermoplastic resin and higher than the temperature of the external heating roll to thermally adhere the thermoplastic resin sheet or film to the external heated roll or the heated, endless metal belt. The thermoplastic resin sheet or film is then moved along on the external heated roll or belt into a high temperature zone.
