Title: Scramjet engine having improved combustion cycle
Inventor: COFFINBERRY GEORGE A
IPC: F02K7/10
Filed: 1991-01-17
Abstract: Abstract of the Disclosure A method of operating a scramjet engine having an improved low pressure combustion cycle is disclosed.  Apparatus for carrying out the method is also disclosed. The method includes the steps of providing supersonic compressed airflow to a combustor and supplying fuel to the combustor for generating a fuel/air mixture having a predetermined temperature less than a temperature required for spontaneous ignition of the fuel/air mixture.  The method also includes igniting the fuel/air mixture for sustaining recombination reactions of the fuel/air mixture for generating combustion gases.  In the preferred embodiment, the fuel/air mixture is ignited by generating a boundary layer of airflow having atomic oxygen and channeling the boundary layer into the combustor for mixing with a portion of the fuel for generating a boundary layer fuel/oxygen mixture subject to spontaneous ignition.  The method results in combination at a relatively low temperature and pressure which is effective for increasing the combination rate for providing more complete combustion of the fuel/air mixture while additionally providing primary pressure increase in the combustor as compared to an inlet of the scramjet engine.

Patent CA-2042484-A1 (CA)
Title: Ball bat
Inventor: YOU CHIN-SAN
IPC: A63B60/06
Filed: 1991-05-13
Abstract: A ball bat comprises an impact portion, a grip portion, and a flexible bending portion situated between the impact portion and the grip portion. The bat is characterized in that it comprises a fiber-reinforced plastic casing of a predetermined thickness.  The slits of a predetermined  number are constructed in the casing located at the junction area of flexible bending portion and grip portion. The number of fibers incised to form slits is in a predetermined proportion to the total number of fibers contained in the casing located at the junction area, with the ratio being in the range of 5%-95%. The slits serve to obstruct the transmission of shock from the impact portion to the grip portion of the ball bat. Rigidity and elasticity of the impact portion are different from those of grip and flexible bending portions by virtue of an existence of slits disposed in the latter. Rigidity and elasticity of the junction  area of flexible bending portion and grip portion can be adjusted by means of slits to an extent that the optimumeffect of swinging is attained. A covering layer made of a polymeric material  can be used to encase the area, where slits are constructed, for the dual purposes of protecting the area and of absorbing the residue of shock.

Patent CA-2045791-A1 (CA)
Title: Branch performance in high speed processor
Inventor: SITES RICHARD L
IPC: G06F9/38
Filed: 1991-06-27
Abstract: BRANCH PREDICTION IN HIGH-PERFORMANCE PROCESSOR          ABSTRACT OF THE DISCLOSURE      A high-performance CPU of the RISC (reduced instruction set) type employs a standardized, fixed instruction size, and permits only simplified memory access data width and addressing modes.  The instruction set is limited to register-to-register operations and register load/store operations.  Byte manipulation instructions, included to permit use of previously-established data structures, include the facility for doing in-register byte extract, insert and masking, along with non-aligned load and store instructions. The provision of load/locked and store/conditional instructions permits the implementation of atomic byte writes.  By providing a conditional move instruction, many short branches can be eliminated altogether.  A conditional move instruction tests a register and moves a second register to a third if the condition is met; this function can be substituted for short branches and thus maintain the sequentiality of the instruction stream. Performance can be speeded up by predicting the target of a branch and prefetching the new instruction based upon this prediction; a branch prediction rule is followed that requires all forward branches to be predicted not-taken and all backward branches (as is common for loops) to be predicted as taken.  Another performance improvement makes use of unused bits in the standard-sized instruction to provide a hint of the expected target address for jump and jump to subroutine instructions or the like.  The target can thus be prefetched before the actual address has been calculated and placed in a register.  In addition, the unused displacement part of the jump instruction can contain a field to define the actual type of jump, i.e., jump, jump to subroutine, return from subroutine, and thus place a predicted target address in a stack to allow prefetching before the instruction has been executed.  The processor can employ a variable memory page size, so that the entries in a translation buffer for implementing virtual addressing can be optimally used.  A granularity hint is added to the page table entry to define the page size for this entry.  An additional feature is the addition of a prefetch instruction which serves to move a block of data to a faster-access cache in the memory hierarchy before the data block is to be used.
