Patent CA-2239165-A1 (CA)
Title: Refuse bag opener
Inventor: MUMA MICHAEL J
IPC: B02C18/22
Filed: 1998-05-28
Abstract: A refuse bag opener that includes a material metering cylinder and a knife cylinder mounted therein and driven by suitable power means to rotate in opposite directions to feed bagged refuse therebetween. The metering cylinder and the knife cylinder are disposed in vertical spaced relation with the knife cylinder being the lowermost of the two. The hopper receives the bagged material and by way of a sloping lower wall directs the bagged material towards the knife cylinder. The lower sloped wall has a belt conveyor for direct feeding of the bagged material to the lower cylinder which by virtue of its rotation cuts the bag. The bagged refuse passes between the metering cylinder and the knife cylinder at a relatively even rate. A conveyor feeds the material from a supply source to the hopper and an outfeed conveyor delivers the emptied bags and contents of the bags to a suitable sorting location. Feed to the cutting cylinder is preferably no more than one bag deep and the feed is controlled by signals received from a sensing means to control the hopper feed conveyor and/or an infeed conveyor within the hopper. The metering cylinder has a plurality of flexible members radiating outwardly from a shaft and are spaced circumferentially therearound. The outwardly radiating members are flexible. The hopper has an inlet end thereto offset horizontally in an upstream direction from the metering cylinder and knife cylinder.

Patent CA-2280214-A1 (CA)
Inventor: MEIER ROLF GEORG
IPC: H04M19/00
Filed: 1999-08-10
Abstract: In the occurrence of a data modem establishing a data communication session over a telephone line, a method is disclosed for detecting the modem and subsequently reducing the telephone line current. Initially, when a new telephone call is begun, the line current is set as normal to a current sufficient to power a standard telephone handset.      Subsequently, using modulation detection techniques, it is determined whether a modem data session has been initiated on the particular telephone line. If such a session has begun, the normal current level on the telephone line is unnecessary since data modems are locally powered. To minimize wasted power and reduce thermal problems caused by the modem dissipating the excessive current, a reduced current is set on the telephone line. This reduced current is either a predetermined modem current level or a minimum allowable current for the particular telephone line, as calculated within the line interface circuit.

Patent CA-2283998-A1 (CA)
Inventor: GRAVES JEFFREY
IPC: G01N27/403
Filed: 1998-03-10
Abstract: The present invention is an electronic wiring substrate for sensors formed over a subminiature through hole. Because of the small diameter of the through hole, the material that fills the through hole and the through hole itself have an essentially negligible effect on the sensor. Only a small amount of conductive material which fills each through hole is in contact with each associated electrode. Therefore, the purity of the electrode is not significantly altered by the conductive material coupled to the electrode. A  relatively large number of sensors can be formed on the surface of the substrate within a relatively small fluid flowcell. Thus, more information can be attained using less blood. The substrate is essentially impervious to aqueous electrolytes and blood over long periods of storage in potentially corrosive environments. Since the substrate does not break down or become unstable when exposed over time to such reactive environments, the isolation that is provided by the substrate remains very high between each sensor and each other sensor, between each sensor and each conduction path, and between each conduction path and each other conduction path. The superior isolation provided by the substrate provides for a high level of accuracy in the sensor of the present invention. This physical isolation of the sample from the conduction paths between the sensor electrodes and external devices ensures very high electrical isolation between each of the sensors, is maintained over an extended period time during which corrosive fluids (such as electrolytes and/or blood) are present in the flowcell.
