Patent CA-2496656-A1 (CA)
Title: Finned tube heat exchanger and method
Inventor: FERGUSON MARK ALLEN
IPC: F28D7/02
Filed: 2005-02-10
Abstract: A high efficiency heat exchanger is shown which can be incorporated into a finned tube water heater. The heat exchanger has a pair of flow manifolds each having a water inlet and a water outlet and a series of connecting openings. Circular flow tubes have connecting ends which fit within the connecting openings of the manifold so that the tubes are arranged in a stacked fashion to form a tube bundle. When incorporated into a water heater, a burner communicates with the interior space within the stacked tube bundle for producing products of combustion for heating water flowing in the flow tubes. The flow tubes have external fins which are crushed to form upper and lower flat stacking surfaces for stacking the tubes to form the tube bundle. The fins are also crushed to form angled baffled surfaces about a external periphery of the tubes. The baffle surfaces serve to retain heat from the products of combustion of the burner which are released into the interior space within the stacked tube bundle. A method of corrosion protecting the heat exchanger is also shown.

Patent CA-2511617-A1 (CA)
Title: Quick assembly hot runner nozzle design
Inventor: MEKSAVANH BOUNOTH
IPC: B29C45/20
Filed: 2005-07-06
Abstract: The present invention is a hot runner nozzle design consisting of a nozzle core with slotted flange seated inside a slotted nozzle housing, a nozzle tip seated on the nozzle core, and a nozzle tip seal seated on the nozzle tip. Furthermore, the present invention is a quick assembly hot runner nozzle design. The present nozzle design provides for the easy installation and removal of the nozzle by means of turning and sliding the nozzle. This provides for easy installation or removal of the nozzle when servicing the mold in the machine and without the complete disassembly of the hot runner mold. The seal located on the nozzle tip seals the tip area to avoid plastic leakage. Positioning the seal closer to the gate area also contributes in increased nozzle tip mass thus resulting in a better heat distribution profile along the nozzle tip, and especially in the area closer to the gate. This eliminates nozzle tip freeze up, a critical matter for inside center gate applications that may have extended nozzle tips or tight pitch applications. Furthermore, the seal seated on the nozzle tip allows for a better concentric alignment of the nozzle to gate. Also, positioning the seal close to the gate area decreases color change time because of less volume being trapped around the nozzle tip.

Title: Method for estimating signal magnitude, noise power, and signal-to-noise ratio of received signals
Inventor: PIETRASKI PHILIP J
IPC: H04L27/38
Filed: 2004-08-24
Abstract: An improved system and method for estimating one or more parameters, such as amplitude and signal-to-noise ratio, of a received signal, such as an M-QAM or q-ASK signal, is set forth herein. A first embodiment of the invention estimates the amplitude of an M-QAM signal based upon known or ascertainable phase information regarding a plurality of transmitted symbols. A respective set of received symbols corresponding to the plurality of transmitted symbols is recovered. Each of the plurality of received symbols is multiplied by a complex unit vector with a phase that is opposite in sign to the complex transmitted data symbol to generate a set of products. The set of products is summed, and the real part of the sum of products is then determined. The absolute values of the known transmitted symbols are summed to generate a total magnitude value. The real part of the sum of products is divided by the sum of transmitted magnitude values to generate an estimate of the amplitude of the M-QAM signal. Other embodiments of the present invention utilize second-order and fourth-order moments of received samples, a maximum likelihood searching process, or a Kurtosis estimation process to estimate amplitude, noise power, and signal-to-noise ratio of a received signal.
