Title: Radiant and convective heat resistant materials and emergency fire shelter made therefrom
Inventor: ACKERMAN MARK Y
IPC: B32B5/26
Filed: 2003-01-06
Abstract: The invention is a new heat and fire resistant material and an improved wildland fire shelter and kit. The material is made of a woven silica-based cloth layered in several possible combinations with foil and fiberglass cloth layers. The layers can be arranged in a variety of sequences to minimize the thermal radiation to the inside of the material or shelter.      However, a foil layer must always be the outermost layer to provide protection from radiant heat and a layer of foil must be present between the interior of the shelter or material and any layer of adhesive to limit accumulation of gases inside the shelter if the adhesive or other substance should break down when exposed to heat. The silica cloth, aluminum foil, and fiberglass cloth may be laminated or sewn together. The shape of the fire shelter is a half cylinder with 1/4 sphere at each end. The shelter is contained in an easy-open polyvinyl bag which provides for quick removal and deployment of the fire shelter.

Title: A liner for reinforcing a pipe and method of making the same
Inventor: RENAUD CLAUDE M J G L
IPC: F16L55/18
Filed: 2001-08-27
Abstract: A reinforcement liner and methods of manufacturing the liner are disclosed.  The liner includes a fabric (100) material having first and second support layers (110, 120). Each of the layers includes reinforcing fibers (112, 122).  The first and second support layers are oriented in different directions to provide support to the liner in those directions. The liner includes a stitching material (130) that is used to couple the first and second support layers together. The stitching material is preferably an elastic yarn. One of the support layers includes long, chopped strands that are oriented parallel to each other. The long, chopped strands are directed so that they are in the peripheral direction of the finished reinforcement liner. The long, chopped fibers can be distributed continuously or only along portions of the width of the fabric. The disclosed methods of manufacturing a liner include alternative processes by which the liner can be made. The fabric is manufactured in the form of a continuous roll (160). One method involves winding the roll in a helical pattern about a fixed mandrel (42). Another method involves mounting several rolls circumferentially about a mandrel. The rolls are mounted so that strips of fabric from each roll overlap a portion of adjacent fabric strips to provide a continuous liner surface on the mandrel.

Title: Carbon monoxide hydrogenation
Inventor: KOVEAL RUSSELL JOHN
IPC: B01J25/00
Filed: 2001-08-03
Abstract: A method is disclosed for enhancing the activity of a particulate Dispersed Active Metal (DAM) catalyst during operation of a reactor wherein the hydrogenation of carbon monoxide to produce a mixture of hydrocarbons is being carried out comprising withdrawing a mixture of hydrocarbons and a portion of the DAM catalyst from the reactor, reducing the hydrocarbon content thereof with hydrogen at a temperature above the temperature of the reactor, oxidizing a slurry of the catalyst particles in a suitable fluid at low temperature to form an oxidized precursor, reducing the precursor at elevated temperature to reform the catalyst and returning it to the reactor. The catalyst may be passivated before returning it to the reactor. The process is carried out until it is evident that the operation of the reactor will no longer be economical due to a decrease in catalyst performance or accumulation of fines at which point the catalyst is preferably renewed during operation of the reactor by a process comprising withdrawing a mixture ofhydrocarbon content thereof, heating the mixture above the melting temperature of at least one of the metals to form a melt, removing any slag that forms on the melt, cooling the melt to form a solid, reducing the particle size thereof to form a renewed particulate DAM catalyst, which is then returned to the reactor.
