Inventor: ANDERSON RICHARD C
IPC: F41H11/02
Filed: 1996-04-23
Abstract: Leurre (10) infrarouge à intensité infrarouge renforcée. Le leurre comporte une structure (12) dans laquelle est placée une composition (14) éclairante infrarouge. Le diamètre de l'âme et la longueur de la structure sont choisies de façon avantageuse en vue d'une compatibilité avec les distributeurs de paillettes préexistants et leurs cartouches situées sur l'aéronef. La composition éclairante, la zone du col de tuyère, la géométrie de la composition éclairante et le volume de la chambre de combustion sont choisis de telle façon que la combustion de la composition éclairante provoque un état de combustion instable pendant la première seconde de combustion, ce qui augmente l'intensité maximale de la radiation émise par l'agent propulseur. De préférence, le leurre est configuré de telle façon que la combustion instable se produit au cours d'un intervalle de 0,2 à 0,5 secondes après le début de la combustion de la composition éclairante.

Patent CA-2243817-A1 (CA)
Title: Multi-component recovery apparatus and method
Inventor: FINLEY STEVEN J
IPC: B01D8/00
Filed: 1998-07-23
Abstract: An apparatus and method for recovering one or more components from the vapor feed in which the component is recovered from the vapor feed at a lower pressure within a lower pressure cold trap. Thereafter, a higher pressure cold trap is connected to the lower pressure cold trap and the component revaporizes in the lower pressure cold trap and resolidifies in the higher pressure cold trap. The higher pressure cold trap is then isolated and the component is allowed to thaw to build up a vapor pressure such that the component can be delivered for recovery at a high pressure. Two or more components having higher and lower boiling points can be recovered by low pressure cold traps set in series. Low pressure cold traps can be provided to operate in an out of phase relationship so that components are frozen on one set of lower pressure cold traps while being vaporized from the other set of cold traps. In the case of two component recovery, two high pressure cold traps are provided to allow two components to vaporize and thus develop a sufficient vapor pressure to be delivered at the requisite delivery pressure.

Title: Apparatus, method and computer program product for controlling access to a target device across a bus
Inventor: ERICSON GEORGE M
IPC: G06F21/00
Filed: 1998-08-19
Abstract: A method, apparatus, and computer program product for controlling access to a target device utilizes an initiator identifier to either permit or deny access to a selected portion of the target device. To that end, a message having the initiator identifier is directed from the initiator device to the target device to request access to the selected portion of the target device. Upon receipt by the target device, it is determined if the initiator identifier is in a permitted set of identifiers associated with the selected portion of the target device. If the initiator identifier is in the permitted set, then access to the portion of the target device is permitted and the initiator can access the target in accordance with conventionally known processes.

IPC: B01D53/86
Filed: 1998-10-09
Abstract: Disclosed is a process for destroying organic halogen compounds (such as dioxins) which are present in a dust-laden gas by oxidative decomposition using a solid catalyst based on zinc oxide, tin oxide, zirconium dioxide, silicon dioxide, iron oxide, aluminum oxide or titanium dioxide in the presence of oxygen.  The dust-laden gas is brought into contact with the catalyst at a temperature in the range from 60°C to below 250°C.          The present process is used, for example, for treating dust-laden off-gases or dust-laden exhaust air from refuse combustion plants, plants for cement manufacture, plants for producing, refining and/or processing metals, sintering plants or slag plants.  By the process, organic halogen compounds such as dioxins contained in a dust-laden gas can be destroyed in a single and economical manner.

Title: Method and apparatus for modifications made to a video signal to inhibit the making of acceptable videotape recordings
Inventor: RYAN JOHN O
IPC: H04N5/91
Filed: 1997-05-07
Abstract: A video signal is modified so that a television/receiver still produces a normal picture from the modified signal, whereas videotape recording of this signal produces generally unacceptable pictures. Videotape recorders have an automatic gain control circuit (Fig. 2) which measures the sync pulse level in a video signal and develops a gain control correction signal for keeping the video applied to an FM modulator in the videotape recording system at a fixed predetermined level. A portion of the back porch intervals following the trailing edges of a substantial number of sync pulses are significantly raised and lowered to improve the playability of the original signal without reducing the effectiveness of the copy protection of the copied signal. This is achieved most simply by adding pulses to selected lines of the video signal during the back porch interval, which pulses significantly raise or lower the voltage amplitude during the blanking interval so to provide a signal where the average value is approximately equal to the blanking interval. The sync level and the sync duration on the selected lines are also reduced to enhance the effectiveness of the process.

The segments are highly concave toward the center and less concave with increasing radial distance away from the center.          The width of the segments may increase linearly with radial distance so as to create a constant acoustical resistance radially.  In another embodiment, the present invention is directed to a system containing both the aforesaid center cone, an outer cone with similar radial characteristics but being concave towards its center.  The segments of the outer cone preferably terminate at a flexible, high sound absorption ring.  The center cone fits within an orifice at the center of the outer cone.
