Patent CA-2247702-A1 (CA)
Title: Improvements relating to ostomy appliances
Inventor: STEER GRAHAM E
IPC: A61F5/448
Filed: 1998-09-18
Abstract: An ostomy filter comprises a filter housing (24) having a cylindrical bore (28) within which is received a cylindrical filter element (36). The filter element (36) has an axial length greater than its radius, and is slid longitudinally into the bore (28). A user can select a filter element to use having appropriate flow rate characteristics to suit his or her needs. The filter may be a discrete filter mounted on the pouch wall, or it may be incorporated into a stomal aperture coupling member (16) for the pouch. In one form, the filter element (36) can be replaced by inserting a new filter element through the outer end (30) of the bore, to displace the previous filter element and eject it through the inner end (32) of the bore into the pouch. The filter element may contain superabsorbent for absorbing any liquid which leaks into the filter. The cylindrical filter element may be produced using conventional production facilities used in the cigarette filter industry. An elongate rod of superabsorbent, or superabsorbent containing, material is also disclosed which can be inserted into a pouch, for example, a urostomy pouch, without the need for an additional applicator.

Title: Adaptive array transmitter-receiver
Inventor: FUKAWA KAZUHIKO
IPC: H01Q1/24
Filed: 1998-06-02
Abstract: Received baseband signals from a plurality of antennas 11 1 to 11 Q are linearly combined through multiplication by weighting coefficients, then a decision signal is delayed for one symbol duration, and the delayed signal is multiplied by a feedback filter coefficient w b* to generate intersymbol interference, which is subtracted from the linearly combined output y(i). The subtracted output is subjected to a signal decision to obtain a decision signal, then the difference between the input into a decision unit 17 and the decision signal is obtained as an error signal e(i), and weighting coefficients w1* to w Q and the feedback filter coefficient w b* are estimated in a parameter estimation part 71 so that the square of the error signal e(i) is minimized. At the transmitting side a transmitted signal is delayed for 1T and is then multiplied by the feedback filter coefficient w b*, then intersymbol interference is subtracted from the transmitted signal to distort it, and the distorted signal is multiplied by the weighting coefficients w1* to w Q*, respectively, thereby creating transmitted baseband signals for application to the antennas 11 1 to 11Q

Title: Cover for the box of a pick-up truck
Inventor: BOURGEOIS MAURICE
IPC: B60J7/16
Filed: 1998-10-14
Abstract: A cover assembly for the box of a pick-up truck. The cover assembly has a rigid cover that is sized to fit between the side walls of the box when in the closed position closing the open top of the box. The assembly includes support ledges fastened to the inside of the side walls of the box for supporting the cover in the closed position. The support ledges carry female pivots spaced from the side walls to form gaps. The cover carries male pivots that enter the gaps in the closed position of the cover, the male pivots in a non-cooperating position with the female pivots. When the cover is lifted from either side of the box, the male pivot on the opposite of the box moves to cooperate with the female pivot on that side to form a longitudinal pivot about which the cover swings when opened.

Inventor: IVERS BARRY ALAN
IPC: F02M37/54
Filed: 1998-10-29
Abstract: A fuel system and method for priming a diesel engine fuel system after assembly or when run out of fuel in which the system has a filter that can trap air allowing drainback of fuel to the tank. The system is provided with a fuel priming connection to the injection pump inlet, the connection having a closure for shutting the connection when not in use. A mechanically openable check valve, such as a Schraeder valve, is a preferred form of closure. The system is primed by reverse flow of fuel from the priming connection through the filter to the fuel tank to virtually eliminate trapped air from the system. The engine may then be started with a minimum of cranking. The engine may be restarted after running out of fuel by partially filling the tank and operating the normal feed pump while bleeding air from the system through the priming connection, which is closed prior to engine starting. The engine may then be reprimed after shutdown if required.

Patent CA-2255779-A1 (CA)
Inventor: NARISAWA KAZUHIKO
IPC: A01N63/30
Filed: 1998-03-23
Abstract: Root endophytes which symbiose within a root of crops were separated and classified. A medium which cultured the strains were inoculated with a seed of a crop. The seed was allowed to sprout to inoculate the root of the crop with root endophytes. While growing the crop, the soil for growth was inoculated with soil pathogenic bacteria, and the crop was grown for a period necessary for the occurrence of a soil disease. The crop was inspected for pathopoiesis, and root endophytes, which had been inoculated into the root of crop having low severity, were specified and selected. As a result, it was found that some root endophytes can significantly inhibit soil diseases. Among root endophytes, Heteroconium chaetospira was found to be particularly effective in inhibiting soil diseases.

Patent CA-2260648-A1 (CA)
Inventor: AOYAMA SATOSHI
IPC: B01J19/00
Filed: 1999-02-02
Abstract: A carbon monoxide concentration reducing apparatus that raises the internal temperature of a CO-selective oxidation unit carrying a selective oxidation catalyst in as short a time period as possible after the apparatus is started, and a driving method for the apparatus are disclosed. In addition to the selective oxidation catalyst, the CO-selective oxidation unit contains an oxidation catalyst. The oxidation catalyst is capable of facilitating oxidation of an oxidizable gas component of a hydrogen-rich gas, even at temperatures substantially equal to a normal room temperature.  The oxidation catalyst is, for example, a platinum (Pt) catalyst. Even when the internal temperature of the CO-selective oxidation unit is substantially equal to a normal room temperature, the oxidizable gas component of the hydrogen-rich gas can be oxidized by oxygen contained in an oxidative gas, via the function of the Pt catalyst.  Using heat produced by this oxidation, the temperature of the hydrogen-rich gas can be raised, so that the internal temperature of the CO-selective oxidation unit can be raised to a desired temperature.

Title: Method and apparatus for minimizing mismatch in a complex filter
Inventor: SWAMINATHAN ASHOK
IPC: H03M3/00
Filed: 1999-02-18
Abstract: A complex filter minimizing mismatch error by averaging the mismatch error by integrating the real and imaginary input signals using the same integrator. A  further advantage is that, as compared to known devices, the complex filter uses fewer number of components thereby reducing the consumed power. The complex filter may be used in a complex bandpass sigma-delta modulator, thereby increasing the performance of the sigma-delta modulator. The complex filter used in a sigma-delta modulator analog to digital converter increases performance of the analog to digital conversion since the mismatch noise is minimized. The complex bandpass sigma-delta modulator analog to digital converter include any number of complex filter stages.

Patent CA-2271974-A1 (CA)
Inventor: MACEL BOB
IPC: C07J73/00
Filed: 1999-05-14
Abstract: A process for introducing a 1,2-double bond into 17.beta.-substituted-3-oxo-4-azasteroids includes the preparation of novel 2,2-dibromo-4-azasteroids by a three step process comprising oxalylation, reaction with excess bromine, and removal of the oxalyl group.  This process is preferably carried out at temperatures at or above -20°C and results in a high yield of the 2,2-dibromo-4-azasteroid. The 2,2-dibromo-4-azasteroid can be converted to the corresponding 17.beta.-substituted-4-aza-5.alpha.-androst-1-ene-3-one by at least two processes, one of which involves correcting the oxidation state at the 2-carbon and then introducing the 1,2-double bond, and the other of which involves introducing the unsaturation to produce a vinyl bromide followed by correcting the oxidation state of the 2-carbon. Preferably, the dibromo compound is reacted with thiophenol to produce a 2-phenylthio intermediate, followed by oxidation of the phenylthio group to a sulfoxide and 1,2-elimination of the sulfoxide group to create the 1,2-double bond.
