Title: Optical low-coherence reflectometry using optical amplification
Inventor: SORIN WAYNE V
IPC: G01D5/26
Filed: 1992-10-27
Abstract: A low-coherent reflectometer [100] is disclosed for use in measuring the optical properties of a device 112. The invention utilizes an optical amplifier [135] to amplify the backscattered light thereby reducing the measurement times by a factor equal to the gain. The preferred optical amplifier [135] is a diode-pumped superfluorescent fiber which may act both as the amplifier and the low-coherence light source. Reductions in signal averaging times of a factor of 100 may be achieved by the use of the amplifier. The device includes splitting means 116, adding/combining means 122, detector 132 and means 124 for varying the difference in the optical path lengths travelled by the backscattered light and a split second light signal e.g. a moving mirror. The amplifier 135 may be positioned in other locations along the path of the backscattered light (see figures 2, 4 & 5). <IMAGE>

Title: Cache storage with invalid-line flags
Inventor: JAGGER DAVID VIVIAN
IPC: G06F12/08
Filed: 1993-09-29
Abstract: A data processing system is described having a central processing unit (CPU) 4, a memory management unit (MMU) 6 and a cache memory 8. The CPU 4 makes cache writes in the same clock cycle that the data is output from the CPU 4. In a following clock cycle, the MMU 6 produces a signal IC indicating whether that storage operation was invalid. If the storage operation was invalid then a flag associated with a cache storage line storing a plurality of output data words is set to indicate such invalid storage. Use of a single flag per cache line requires less storage than would use of one "dirty" bit per word. The MMU may also provide virtual-to-physical address mapping. <IMAGE>

Title: Air separation using triple column rectification
Inventor: HIGGINBOTHAM PAUL
IPC: F25J3/04
Filed: 1994-12-06
Abstract: Nitrogen is separated from a first stream of compressed air in a higher pressure rectification column 14 and from a second stream of compressed air in an intermediate pressure rectification column 24. Oxygen-enriched liquid is taken from the columns 14 and 24 and separated in a lower pressure rectification column 42. Impure oxygen product which may be 80 - 97 % by volumn of oxygen, is withdrawn in liquid state from the column 42 through an outlet 70. A part of the first air stream is condensed in a first condenser-reboiler 18, and a part of the second air stream is condensed in a third condenser-reboiler 30. Nitrogen separated in the higher pressure rectification column 14 is condensed in a second condenser-reboiler 22, and nitrogen separated in the intermediate pressure rectification column 24 is condensed in a fourth condenser-reboiler 34. The resulting nitrogen condensate is used as reflux in the columns 14, 24 and 42. The condenser-reboilers 18, 22, 30 and 34 provide reboil for the lower pressure rectification column 42 and thus thermodynamically efficient operation of column 42. A 99.5 % pure oxygen product can be produced from the product withdrawn at outlet 70 by employing a further liquid-vapour mass exchange region below the column 42. <IMAGE>
