Patent CA-2125334-A1 (CA)
Inventor: NAIMPALLY SAIPRASAD V
IPC: H04N5/00
Filed: 1994-06-07
Abstract: A high-definition television receiver includes circuitry to decode a received high-definition television signal to produce a digital data stream representing the corresponding high-definition television image. In addition, the receiver includes circuitry which generates a signal representing a reduced resolution image from the decoded data stream. The receiver provides both the high-definition television signal and the reduced resolution signal at an output port. A video tape recorder (VTR) receives the two signals, segments them and formats them onto the tape in a manner which allows a majority of the reduced resolution segments to be recovered and displayed in at least one of the VTR's trick-play modes. The reduced resolution image may be from the same channel or from a different channel and may also be displayed as an inset picture (PIX-IN-PIX) in the main high-definition image.

Patent CA-2152790-A1 (CA)
Title: Pressure tolerant fuel tank panels
Inventor: TONI DARRYL MARK
IPC: B60K15/03
Filed: 1993-12-30
Abstract: A pressure tolerant composite panel has an inner fiber reinforced layer, an outer fiber reinforced layer and a core disposed therebetween. In one embodiment of the invention, the inner layer (25) has weakening structures (30) incorporated at the peripheral edges thereof, and has an outer layer (26) of a different and lower modulus of elasticity than the inner layer to provide some degree of elongation. When high internal forces are encountered, the weakening structures allow the inner layer to separate, with the outer layers stretching to absorb the forces without failure. Optionally, strengthening straps (28, 29) are positioned about the panel such that it is compartmentalized into discrete sections to contain damage in localized areas. In an alternative embodiment of the invention, the inner core (27) is produced of a crushable material which has a yield strength sufficient to provide structural support under normal operating conditions. When a high pressure is encountered which exceeds the yield limit, the core is crushed to prevent force transmission to the outer layer. Such a composite panel assures survivability of the panel when subjected to impact damage.

IPC: F23J15/06
Filed: 1995-07-13
Abstract: A two-stage downflow flue gas treatment condensing heat exchanger system allows for flue gas to be passed into a two-stage housing at an upper end of the housing.  The flue gas is channeled through a first stage of the housing having a first condensing heat exchanger which cools the flue gas.  The flue gas is then channeled through a second stage having  a  second condensing heat exchanger which is located directly beneath the first stage  and  the first condensing heat exchanger for further cooling  the flue gas. The flue gas travels in a downward direction only through the housing and exits the housing  at the lower end of the housing  beneath the second stage.   A collection tank is located beneath  the  second  stage  of  the  housing  for collecting liquids, condensate, particulate and reaction product.

Patent CA-2157403-A1 (CA)
Inventor: ANGOTT PAUL G
IPC: H05B37/02
Filed: 1994-03-01
Abstract: An illumination level control device (10) is disclosed which sequentially reduces the illumination level of a multi-bulb lamp (12). The illumination level control device (10) incorporates two D flip-flops (38, 40) configured in a master-slave relationship wherein the two D flip-flops (38, 40) change their respective states when the clock (60) sends a positive-edge of the clock signal thereto. A portion (58) of the device (10) sets the two D flip-flops (38, 40) when the wall switch (22) is off for more than a predetermined time. In the case of a three bulb (14, 16, 18) lamp (12), a zero state preventor (56) prevents all of the bulbs (14, 16, 18) from being turned off when the wall switch (22) is in the ON position. The zero state preventor (56) effectively eliminates the state wherein the outputs of both of the two D flip-flops (38, 40) are low.
Patent CA-2157973-A1 (CA)
Title: Data processing system, and a power supply apparatus and a method for its use with a data processing system
Inventor: YAMAMOTO HIROYUKI
IPC: G06F1/26
Filed: 1995-09-11
Abstract: A data processing system that employs a rechargeable battery and supports a full discharge of the battery and that is not shut down even if a user mistakenly removes a battery while the system is being operated in a full discharge mode, and a power supply apparatus for such a data processing system and a method for using the apparatus. When a data processing system is to be operated in a full discharge mode, an external power source constantly and steadily supplies power to the first electric circuitry, while a battery supplies power to the second electric circuitry until the discharge is completed. The first electric circuitry is designed to include components, such as a CPU and a main memory, that may force the entire system to be shut down when the supply of power is abruptly halted to those components. The second electric circuitry is designed to include components, such as a backlight of a liquid crystal display device, that do never cause the entire system to be shut down even when the power supply to only these components is abruptly terminated. Therefore, when a user mistakenly removes a battery while a full discharge of the battery is in progress, only the power supply to the second electric circuitry is stopped, and the whole system will not be shut down. When the power supply arrangement is so designed that only an external power source supplies power in response to the detection of the removal or the battery, only a backlight is turned off at the moment a battery is removed; and immediately turned on so that the task executed by the CPU 11 will not be abruptly terminated.
