What the invention claimed is:
1. A top cuff for golf bag comprising a plurality of golf club insertion compartments and a plurality of club shaft positioning devices respectively provided in said golf club insertion compartments, wherein said club shaft positioning devices each comprise at least one hard locating plate and at least one flexible engagement plate disposed at two sides, said at least one hard locating plate each comprising a plurality of peripheral notches and chamfered ribs alternatively arranged in a line at an outer side thereof, said at least one flexible engagement plate each comprising a plurality of groove means corresponding to the chamfered ribs of said at least one hard locating plate and a plurality of retaining portions corresponding to the peripheral notches of said at least one hard locating plate for pressing on the shaft of each golf club being inserted into the peripheral notches of said at least one locating plate.
2. The top cuff of claim 1 wherein said club shaft positioning devices each comprise at least one hard locating plate and at least one flexible engagement plate alternatively disposed at two sides at different elevations.
3. The top cuff of claim 1 wherein the at least one hard locating plate and the at least one flexible engagement plate of each of said club shaft positioning devices each have a wall thickness gradually thinner toward a mid point between the at least one hard locating plate and the at least one flexible engagement plate.
4. The top cuff of claim 1 wherein the groove means of said at least one flexible engagement plate are shadow grooves one a top sidewall of each of said at least one flexible engagement plate.
5. The top cuff of claim 1 wherein the groove means of said at least one flexible engagement plate are parallel slots cut through a front side of each of said at least one flexible engagement plate.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method of making a material system for use at a predetermined use temperature in a high temperature environment, the method comprising:
forming a plurality of geometric shapes at a manufacturing temperature in excess of the use temperature to render the geometric shapes dimensionally stable at the use temperature;
filling at least a portion of a chamber with the plurality of geometric shapes such that the geometric shapes define void spaces therebetween and at least a portion of the geometric shapes are not bound to each other when placed into the chamber;
introducing a slurry comprising a carrier medium and a binder material into the chamber;
impregnating binder material into the void spaces and removing carrier medium from the chamber by vacuum impregnation to form a green body;
heating the green body to a processing temperature at which the geometric shapes do not sinter and that is less than the manufacturing temperature to form the material system adapted for use at the use temperature, wherein the forming includes stabilizing the geometric shapes so that the geometric shapes do not sinter to one another at a temperature at which the geometric shapes would sinter together prior to stabilization.
2. The method of claim 1, wherein the geometric shapes are hollow, achieve dimensionally stability by being manufactured at a temperature in excess of 1600\xb0 C. and comprise an oxide based composition.
3. The method of claim 1, wherein the binder material comprises an aluminum phosphate based composition.
4. The method of claim 1, wherein the binder material is adhered to the geometric shapes by sintering the binder material to the geometric shapes at a temperature between 400\xb0 C. and 1600\xb0 C.
5. The method of claim 1, wherein the material system is adapted for use in a combustion turbine engine by utilizing a chamber having a three dimensional shape that forms the material system to be near net shape for one of an airfoil and a combustor liner.
6. The method of claim 1, further comprising introducing the slurry into the chamber through a first opening and applying a vacuum to the chamber through a filter to remove the carrier medium while retaining the binder material within the chamber.
7. The method of claim 1, further comprising applying a first vacuum level to the chamber during a first period of time and applying a second vacuum level greater than the first vacuum level to the chamber during a second period of time.
8. The method of claim 1, further comprising forming the slurry to comprise the carrier medium, the binder material and a filler material.
9. The method of claim 1, further comprising infiltrating aluminum hydroxyl chloride into the green body.
10. The method of claim 1, further comprising forming the geometric shapes to be hollow spheres with sphere walls of 70\u2013100% of theoretical density.
11. The method of claim 1, wherein a majority of the geometric shapes are not bound to each other when placed in the chamber.
12. The method of claim 1, wherein all of the geometric shapes are not bound to each other when placed in the chamber.
13. The method of claim 1, wherein the geometric shapes are spheres.
