Title: Vent damper including pivoting poppet
Inventor: SCHIMMEYER WERNER K
IPC: F23L11/00
Filed: 1998-11-02
Abstract: A vent damper is provided for limiting the flow of ambient air through the central core of a hot water heater having a combustion chamber, the central core forming an exhaust port leading to an exhaust duct for evacuation of exhaust gases from the combustion chamber.  The vent damper includes an annular base having an upwardly facing opening forming a passageway therethrough for passage of the exhaust gases from the exhaust port to the exhaust duct. A  poppet is pivotally supported above the annular base means to pivot between a closed position closing the passageway and a open position opening the passageway. The poppet is configured such that the exhaust gases generated in the combustion chamber and passing out of the exhaust port cause the poppet to pivot into the open position such that the gases may flow through the passageway.  The weight of the poppet is distributed about a pivot such that in the absence of the gases, it falls under the influence of gravity into the closed position to limit the flow of ambient air through the central core. A down draft hood is disposed between the poppet and the exhaust duct to provide down draft protection. The down draft hood includes side ports to allow the gases to flow from the exhaust port to the exhaust duct when the passageway is open. The down draft hood permits operational lifting of the closure element even in a downdraft situation. A flue hood covers the down draft hood.

Patent CA-2267425-A1 (CA)
Title: Cosine segment communications system
Inventor: ERISMAN DAVID E
IPC: H04L27/18
Filed: 1997-10-06
Abstract: A digital communication system (fig. 1) is disclosed which is unique in that it modulates a sinusoidal carrier with discrete cosine segments (fig. 13). The discrete cosine segments may contain different time and amplitude values. The discrete cosine segments may be combined with each other (fig. 13) or with zero slope level segments (fig.  12) in order to effectively modulate the sinusoidal carrier. Rather than employing the use of filters (20) for controlling instantaneous voltage changes, the present communication system (fig. 1) forces the bit edges of the discrete cosine segments to occur at the zero slope points of a cosine wave, where no voltage changes occur. The communication system (fig. 1) utilizes direct digital synthesis (12, 14, 15, 16) in order to create a carrier signal which closely represents sinusoidal carrier signal. The present communication system (fig. 1) may be used in conjunction with various conventional methods such as phase shift keying (fig. 12) and amplitude shift keying (fig. 13). Means (fig. 5) are also provided for demodulating the carrier signal in order to recover the original baseband signal.

Title: Apparatus and method for testing subscriber line
Inventor: OKAZAKI KENICHI
IPC: H04B3/46
Filed: 1999-07-22
Abstract: There are provided two line monitoring resistors 63a, 63b of high resistance (Rt1, Rt2) branched at nodes 64a, 64b from subscriber line (LN) 3 in line circuit (LC) 4 and connected between each node and earth, and arithmetic operation unit (EP) 60 into which terminal voltages Vt1, Vt2 of line monitoring resistors 63a, 63b are inputted. Arithmetic operation unit 60 monitors Vt1, Vt2 for a predetermined time when subscriber terminal 2 is in on-hook, and hence detects unbalance of DC voltage of both lines and voltage induced on subscriber line 3 to estimate line resistance. When the subscriber terminal is off-hook, line resistance of the line is estimated using a difference between a theoretical value of Vt1, Vt2 when the line is open and silent and a corrected value in a silent state when the sound component is removed.

Title: Method of transmitting clock signals, method of synchronizing clock generators or network elements, as well as a network element and a clock generator
Inventor: WOLF MICHAEL
IPC: H04L1/20
Filed: 1999-09-28
Abstract: To synchronize the network elements in synchronous digital telecommunications networks, a received clock signal or a clock signal derived from a received message signal is selected by each network element for synchronization based on the clock quality. While message signals contain a synchronization status message that indicates the clock quality, signaling of the clock quality was hitherto impossible in the case of clock signals transmitted through simple clock interfaces.        Disclosed are a method of transmitting clock signals (CS) in a synchronous digital communications network and a method of synchronizing clock generators (SSU) or network elements (SEC) wherein signaling of the clock quality is effected by phase-modulating the clock signal (CS). The clock signal (CS) is transmitted and received through simple clock interfaces (T4, CLO; T3, CLI) and contains a phase modulation characteristic of the clock quality. The phase modulation is detected and quality information is derived therefrom. Based on the quality information, the clock generator (SSU) or the network element (SEC) are synchronized to the clock signal. Also disclosed are a clock generator (SSU) and a network element (SEC; NE) for carrying out the two methods.

Title: Hydrocarbon synthesis with cryogenic nitrogen removal upstream of the syngas generation
Inventor: COULALOGLOU CONSTANTINE A
IPC: F25J3/02
Filed: 1998-05-05
Abstract: In a hydrocarbon synthesis process, nitrogen is cryogenically removed from natural gas to produce a synthesis gas feed comprising methane which is substantially free of nitrogen. This feed is converted to a synthesis gas comprising a mixture of H2 and CO which is substantially free of the HCN and NH3 hydrocarbon synthesis catalyst deactivating nitrogen species. This reduces the need for rejuvenating the hydrocarbon synthesis catalyst. During the cryogenic separation, C2+  hydrocarbons are separated from the natural gas and all or a portion of the separated C2-C4 hydrocarbons are added to the methane feed before it is converted into syngas, to increase syngas production.    All or a portion of the separated C2-C3 hydrocarbons may be removed as LPG.
