Abstract: FUSED METALLIC FRICTION MATERIALS     Abstract of the Disclosure A friction material member particularly useful in high load and temperature applications and a method for making the same are disclosed. The friction material member is made by preparing a mixture of sinterable metal particles, carbonaceous material, friction enhancers and curable poly-meric resin; the mixture comprising at least about 50 percent by weight of metal particles and sufficient resin to coat and bond the metal particles, carbonaceous material and friction enhancers.  The mixture is molded and the resin cured to form a piece in a solid preformed shape corresponding to the shape of the mold.  Thereafter, the preformed piece is heated in a substantially oxygen free atmosphere for a time and at temperatures and pressures sufficient to fuse at least a portion of the metal particles into a sintered metal matrix.  The preformed piece may be sintered to a metal backing plate during the heating step, or may be welded, brazed or soldered to the plate after heating.  The resulting product may be classified as a hybrid friction material, i.e., being a cross between semi-metallic and sintered full metallic friction materials.

Granted: 1986-12-16
Abstract: ABSTRACT A computer generates alphanumeric configurations of bingo cards seriatim by using a random number program, then compares the new bingo card sequentially with all cards previously stored in a memory. The computer rejects the new card if it is the same as a stored card and generates a new card.  If the card is different from all previously stored cards then it is stored in memory.  Each time a card is stored in memory, the computer calculates the total number of cards.  When the total has advanced by a given increment, the computer causes a laser printer to print the incremental cards on fan-folded paper.  After each card is stored in memory, the computer generates a new card.
