Patent CA-2544437-A1 (CA)
Inventor: NEW LEVI
IPC: B02C19/06
Filed: 2004-10-18
Abstract: A venturi (18) receives incoming material through an inlet tube (12) and subjects the material to pulverization. The material, as it undergoes pulverization, is further subject to moisture extraction and drying. An airflow generator (32), coupled to the venturi (18), generates a high speed airflow to pull the material through the venturi and into an inlet aperture in the airflow generator. The airflow generator directs the received pulverized material to an outlet where the material may be subsequently separated from the air.

Title: Composition comprising polymeric material and uses thereof
Inventor: MULHBACHER JEROME
IPC: A23L29/00
Filed: 2005-02-09
Abstract: Compositions for the selective delivery of an agent comprising an uncrosslinked starch modified by an acidic group and an agent are described.  The compositions are substantially resistant to degradation and thus result in no or substantially no release of the agent in a first environment, and are capable of degradation in a second environment thereby allowing release of the agent. The pKa of the acidic group of the uncrosslinked starch used is higher than the pH of the first environment and lower than or equal to the pH of the subsequent environment. Also described herein are methods of preparing the compositions, methods of using the compositions and the uncrosslinked starch modified by an acidic group, and corresponding commercial packages.

Title: Conveyor chain support for feeder house
Inventor: HOGUE JEFFREY WAYNE
IPC: A01D61/00
Filed: 2006-10-12
Abstract: A pivoting mid-floor section for use in a feeder house in an agricultural combine is located between the transverse drum and the transverse sprocket means. The pivoting mid-floor can move or adjust when a large volume of crop material is fed into the feeder house, while providing support for the conveyor chain along substantially the entire length of travel between the transverse drum and sprocket means, thus reducing the friction on the chain, and preventing the system slow downs that occurred in feeder house systems using a fixed mid-floor. Additionally, replaceable wear-resistant surfaces can be affixed to the runners or guides of the mid-floor to further extend wear life and reduce friction between the chain slats and mid-floor.  The friction occurs between the wear pads on the runners or guides and the chain slats, rather than between the chain components and the mid-floor.

The first collection efficiency and the second collection efficiency are substantially equivalent. The circuitry (900) maintains the first sensor (301) and the second sensor (302) at a substantially constant temperature. The circuitry (900) determines a measurement of the frozen liquid based on maintaining the first sensor (301) and the second sensor (302) at the substantially constant temperature. In some examples, multiple sensor systems can be used in combination to improve the accuracy of the measurement.

Patent CA-2573105-A1 (CA)
Inventor: SKRYPNYK VOLODYMYR
IPC: H04Q7/38
Filed: 2007-01-08
Abstract: A method and system for conserving power consumption within a network amplifier.  The system includes a first communication device for receiving a Time Division Multiple Access (TDMA) signal. The TDMA signal includes both broadcasting timeslots and non-broadcasting timeslots. A power amplifier amplifies the TDMA signal to generate an amplified TDMA  signal. The TDMA signal is analyzed by a sensing circuit for detecting the presence of the broadcasting timeslots. The sensing circuit turns the power amplifier on during the broadcasting timeslots and off during the non-broadcasting timeslots so that the power amplifier only amplifies the TDMA signal during the broadcasting timeslots and does not amplify the TDMA  signal during the non-broadcasting timeslots. The resultant amplified TDMA  signal is then transmitted by a second communication device.

Inventor: BEAINI PETER J
IPC: F24H1/12
Filed: 2007-01-30
Abstract: With energy prices continuing to increase and the need to reduce greenhouse gases from building space conditioning it is becoming very important to come up with new innovative ideas to reduce energy consumption in all existing and new buildings, especially in multi-unit residential buildings (apartments and condominiums).     The idea of using less energy is becoming very popular in the construction business:  through more efficient building envelopes (increased levels of  wall and roof insulation, more efficient windows etc ---}, or by heat recovery ventilation to pre-condition fresh air through air exchangers, higher efficiency hot water boilers and the substitution of fossil fuels with renewable energy.     In fact there is global environmental initiative which calls for all new buildings and major renovations to reduce their fossil-fuel greenhouse-gas-emitting energy consumption by 50 per cent immediately, increasing, this reduction to 60 per cent in 2010, 70 percent in 2015,80 per cent in 2020, 90 per cent in 2025, and finally, that all new buildings be carbon neutral by 1030.     There is tremendous energy wastage during the hours of the morning and the evening when multiples showers, baths or dishwashers usage are at peak, due to the large amount of warm and hot water going down the drains into city sewage systems.     The new CGWHR "Central Grey Water Heat Recovery" with CDHR "Central Domestic Heat Re-inject" concept recovers energy from hot water going down the drain at 22 to 32 °C (80 to 90°F) to the sewer system and re-injects the heat into the main domestic hot water supply, line. Once the heated domestic hot water enters the building, a heat pump is used to create a cold 15 °C (60 °F) and a hot 49 °  C(120°F).
