A gas preheater () that includes an exit plate () having first and second sides () and a plurality of through holes () and at least one body () mounted adjacent the first side (), the at least one body () having a first end () and a second end (), the second end () located between the body first end () and the exit plate first side (), at least one sidewall () connecting the first and second ends (), a body opening () in the first end () extending into the body () and defining a body inner wall (), and a plurality of passages () extending between the at least one sidewall () and the body inner wall ().

Gas preheater for chemical vapor processing furnace

A template () configured for use with an annular preform () having a periphery () and an inner opening (), the template () having an annular body with an outer periphery () and an inner opening () and a plurality of spacer openings () through its body each for receiving a spacer (), one of the template inner opening () and the template outer periphery () having a width equal to the width of the preform inner opening () or the preform outer periphery (). Also a method for densifying preforms that includes a step of positioning spacers using a template.

Template for arranging spacers on a preform and method of densifying a preform including the use of spacers positioned by a template

Method for densifying a porous carbon preform (). The method includes the steps of: (a) providing the apparatus (); (b) charging the apparatus () with a plurality of stacks of annular porous carbon preforms (), the preforms being separated from one another by spacers (); (c) locating the charged apparatus () in a furnace at a temperature in the range of 950-1100&#xb0; C. and a pressure in the range of 5-40 torr; and (d) circulating a natural gas reactant blended with up to 15% propane through the apparatus for a period of from 150 to 900 hours. Carbon-carbon composite preforms made by this method may be configured as aircraft landing system brake discs or racing car brake discs.
