Patent CA-2295898-C (CA)
Inventor: SCHEUNEMAN THEODORE W
IPC: A01M13/00
Filed: 2000-01-17
Granted: 2007-07-31
Abstract: An evaporator which provides formic acid vapour at a consistent and repeatable rate for effective treatment of varroatosis in honey bees. The evaporation chamber is heated by an electrical element(s) and maintained at a constant temperature by a mechanical thermostat or electronic control circuit. The amount of vaporised material is controlled by adjusting the temperature setting and metering apertures of the evaporation chamber. A continuous flow of formic acid vapour has been demonstrated to kill tracheal and varroa mites much more effectively than other methods and systems, now in use, which depend primarily on the amount of heat generated within the hive as well as solar radiation and ambient temperatures for their operation. The evaporator is made using materials which are largely unaffected by corrosive chemicals, such as formic acid. All electrical components are protected from moisture and corrosion with a protective coating.
Patent CA-2307854-C (CA)

Abstract: The present invention generally relates to mechanisms for preventing undesirable oxidation (i.e., oxidation protection mechanisms) in composite bodies. The oxidation protection mechanisms include getterer materials which are added to the composite body which gather or scavenge undesirable oxidants which may enter the composite body. The getterer materials may be placed into at least a portion of the composite body such that any undesirable oxidant approaching, for example, a fiber reinforcement, would be scavenged by (e.g., reacted with) the getterer. The getterer material(s) may form at least one compound which acts as a passivation layer, and/or is able to move by bulk transport (e.g., by viscous flow as a glassy material) to a crack, and seali ng the crack, thereby further enhancing the oxidation protection of the composite body. One or more ceramic filler materials which serve as reinforcements may have a plurality of superimposed coatings thereon, at least one of which coatings may function as or contain an oxidation protection mechanism. Specifically, a coating comprising boron nitride which has been engineered or modified to contain some silicon exhibits improved corrosion resistance, specifically to oxygen and moisture. The coated materials may be useful as reinforcing materials in high performance composites to provide improved mechanical properties such as fracture toughness. The present invention also relates to improved composites which incorporate these materials, and to their methods of manufacture.

Abstract: The scale of circuit can be small. A demodulating circuit (1A) quadrature-detects a received signal generated by time-multiplexing digital signals which are respectively BPSK-, QPSK-, and 8PSK-demodulated. From the outputs I and Q of the demodulating circuit (1A), a timing circuit (30) detects a burst symbol signal interval. A pattern reproducing circuit (40) outputs the same PN code pattern as on the transmission side. Inverting circuits (13, 14) output RI and RQ on receiving I and Q respectively if the bit of the PN code pattern is "0" and output RI and RQ on receiving -I and -Q respectively if the bit is "1". In a phase error table (ISA) listed are the phase error between the phase at a received signal point and the absolute phase of each output of the inverting circuit (13, 14) for the first quadrant of RI and RQ. A phase error detecting circuit (16A) reads phase error data corresponding to the absolute values of RI and RQ and adjust the data to data according to the quadrants where RI and RQ are present. A carrier reproducing circuit (10A) corrects the phase of a reference carrier used for the quadrature detection so that the adjusted phase error data may be zero.
