Patent CA-2489075-A1 (CA)
Inventor: MULERA TOM G
IPC: G01P3/489
Filed: 2003-06-10
Abstract: An electronic circuit measures a pulse frequency and/or a pulse period of pulses in a sensor signal originating in a sensor coil, the pulses being zero crossing pulses. The circuit includes a filter stage having an input connected to the sensor coil, the filter stage being for removing electrical noise from the sensor signal to provide a filtered sensor signal. The circuit also has a signal strength sensing circuit connected to receive at least one of the sensor signal and the filtered sensor signal, the signal strength sensing circuit producing a variable threshold signal, which is a substantially monotonically non-decreasing function of a strength of the sensor signal. A  variable threshold zero crossing detector is connected to receive the filtered sensor signal and the variable threshold signal. The variable threshold zero crossing detector has an upper threshold to test for zero crossing in a positive direction and a lower threshold to test for zero crossing in a negative direction. One or both of the thresholds is dependent on the variable threshold signal. The variable threshold zero crossing detector generates a clean square-wave pulse train indicative of positive and negative zero crossings. The circuit also includes an output circuit generating a signal indicative of the pulse frequency and/or the pulse period.

Title: Apparatus and method for exposing comminuted foodstuff to a processing fluid
Inventor: ROTH ELDON
IPC: A23L1/00
Filed: 2003-06-18
Abstract: A contactor apparatus (40) is adapted to expose a comminuted foodstuff (21) such as comminuted meat to a processing fluid such as gaseous or aqueous ammonia or carbon dioxide gas. The contactor apparatus (40) facilitates an even and consistent exposure to the processing fluid throughout the comminuted foodstuff as the foodstuff is pumped through a conduit. In order to produce this desired exposure to the processing fluid, the apparatus shapes the comminuted foodstuff into a relatively thin sheet or stream of material flowing through a contact passage (46). The processing fluid is then applied to this relatively thin sheet or stream of comminuted material from a processing fluid chamber (49). A fluid communication arrangement between the fluid chamber and the contact passage (46) allows the flow of processing fluid into the contact passage (46) and into contact with the sheet of foodstuff flowing through the contact passage (46).
Patent CA-2490940-A1 (CA)
Inventor: NGUYEN CONG
IPC: H03F3/45
Filed: 2003-06-26
Abstract: A method for improving or eliminating second harmonic and higher even order distortion terms and balance of fundamental signals in push-pull amplifiers and other differential circuits is disclosed. A common-mode (CM) signal is generated as a sum of two complementary (out of phase) signals in a summation network (32). The CM signal contains even order distortion terms only, while the fundamental signal and odd order distortion terms are canceled, thus providing a correction signal that can be used to reduce even order distortion terms, by injecting the correction signal, with proper phase and amplitude, into suitable circuit nodes. For feedback (70), the correction signal is injected at the input (56, 58) of the amplifiers (16, 18), for feed-forward, it~s injected at the output. The correction signal can be amplified to higher levels and injected into the circuit, without affecting gain of fundamental signals; and can result in significant even order distortion improvements, and improved balance of complementary fundamental signals.

Inventor: MCCARTHY RICHARD OWEN
IPC: C10C3/10

Abstract: The present invention consists of an improved method and apparatus to upgrade bitumen in various forms which comprises four main components; namely, a fractionator equipped with a condenser, a heavy gas oil catalytic treater, a catalyst regenerator/gasifier and a gas cleanup assembly. In operation, the bitumen in liquid form is fed to the fractionator for initial separation of fractions with the bulk of the bitumen leaving the bottom of the fractionator in the form of a heavy gas oil which is pumped to the catalytic treater and sprayed on a hot catalyst to crack the heavy gas oil (an endothermic reaction) to release lighter hydrocarbons in the form of H2 rich volatile matter while depositing carbon on the catalyst. The volatile matter from the treater is directed to the fractionator where the condensable fractions are separated from the non-condensable H2 rich gas, a valuable primary gas. The carbon containing catalyst from the treater is recycled to the regenerator/ gasifier, and the catalyst after being regenerated (an exothermic reaction) is fed hot to the treater. Various fractions are removed from the fractionator as intermediates in the form of light napthas and light oils. The off-gas from the regenerator/gasifier is directed to a gas cleanup system to produce a valuable secondary gas. Both the primary gas and the secondary gas may be further utilized in the processing of the intermediates produced by the method, the primary gas being a source of H2 and the secondary gas being a source of thermal energy.
