Filed: 1995-11-24
Abstract: The  distributed  completion  mechanism  maintains  complex control  dependence  relations  between  instructions  in  a superscalar processor without the cycle time burden associated with large sequential queue structures.  There are global busses, but none of them are cycle limiting (in general, they are almost latch-to-latch paths).   The cost of this completion control mechanism is a large number of tag bits associated with each instruction stage, however, in light of shrinking lithography this cost is small and takes advantage of the strengths of newer technologies.

Patent CA-2186313-A1 (CA)
Title: Microwave thermal trace flowmeter
Inventor: LOVEJOY KIM A
IPC: G01F1/7084
Filed: 1996-09-24
Abstract: A flowmeter is based on the principle of injecting a pulse of microwave radiation into a flowing stream of material containing a substance having an absorption band for the radiation so as to heat a small quantity of the substance and continue its flow in a conduit to a downstream temperature sensor where the temperature of the quantity is sensed  for  enabling  determination  of the  time elapsed for the quantity to travel from the point at which  the  microwave  energy  is  injected  to  the sensor.  A microcontroller receiving  signals from the sensor determines when the peak temperature of the  quantity  is  sensed  and  uses  the  peak  to terminate measurement of a time interval.  The time interval starts when the microcontroller senses that the ac sinusoidal power has passed through zero at which  time  the  microwave  generator,  such  as  a magnetron, emits a pulse of microwave radiation for heating  the  quantity  of  the  substance  of  the material flowing in the conduit.  The microprocessor uses the known distance between where the microwave energy is injected, the cross sectional area of the conduit,  and   the duration of the time for the heated  quantity  of  the  substance  to  reach  the temperature sensor to calculate the volumetric flow of the material in the conduit.  The microcontroller transmits the results of the calculation in terms of digital numbers to various remote flow rate display devices.
Patent CA-2186507-A1 (CA)
Title: Imaging medium and process
Inventor: GAUDIANA RUSSELL A
IPC: B41M5/30
Filed: 1995-04-25
Abstract: A process for producing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizing dye and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizing dye has first and second forms, the first form having substantially greater substantial absorption in a first wavelength range than the second form. The superacid precursor is capable of being decomposed to produce superacid by radiation in a second wavelength range, but is not, in the absence of the sensitizing dye, capable of being decomposed by radiation in the first wavelength range. The secondary acid generator is capable of acid-catalyzed thermal decomposition by unbuffered superacid to form a secondary acid. While at least part of the sensitizing dye is in its first form, the medium is imagewise exposed to radiation in the first wavelength range, thereby causing, in the exposed areas of the acid-generating layer, the formation of unbuffered superacid.  The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid. The components of the acid-generating and color-change layers or phases are then mixed so that the secondary acid causes a change in color of the image dye, and the sensitizing dye is converted to its second form. The acid-generating layer or phase desirably includes a cosensitizer which is a reducing agent less basic than the secondary acid generator.

Title: Treatment cubicle and a method of ventilating a treatment cubicle
Inventor: MILOJEVIC DRAGOSLAV
IPC: B05B16/60
Filed: 1995-05-15
Abstract: The invention relates to a method of ven-tilating a treatment cubicle such as a painting or spraying cubicle used for painting items such as vehicle bodies. The fresh air to be supplied to the cubicle is supplied via an air-permeable ceil-ing (1); an air supply chamber (2) is provided above the ceiling (1) and communicates with an inlet air chamber (3) which is connected via at least one aperture (4) to a fresh air supply sys-tem. The volume of fresh air flowing into the air supply chamber (2) can be regulated by al-tering the aperture (4). The proposed process is characterized by the fact that at least some of the fresh air drawn into the inlet air chamber (3) is forced to flow in a path parallel to the ceiling (1) for a predetermined distance before passing via the aperture (4) into the air supply chamber (2), while the parameters needed to regulate the fresh air flow are measured in the end region of the di-rected air stream. The invention also concerns a treatment cubicle. (Fig. 1)

Abstract: Intracavity particle detection is disclosed using optically pumped laser media.  A laser medium, positioned within a laser cavity, is end-pumped by an optical pump source to excite the laser medium to provide laser light within the laser cavity, and a detecting region, also positioned within the laser cavity and capable of having particles, or particle-containing fluid, therein, is exposed to the laser light whereby light is affected, as by being scattered, by particles in the detecting region with the scattered light being indicative of particles, such as small particles having a size of between 0.05 and 10 microns, causing the light to be scattered so that the scattered light, when collected, can be used to provide an output indicative of particles at the detecting region.  A laser cavity, having therein a solid state laser medium end-pumped by a semiconductor laser providing focused light into the laser medium to achieve gain-aperturing, provides high intracavity power, such as about 550 Watts, to enable detection within the laser cavity of small particles, including particles in a fluid, such as air, passing through the detecting region at high flow rates, including flow rates at, or greater than, one cubic foot per minute.
