Title: Power line communication circuit
Inventor: DELLER ROBERT W
IPC: H04B1/00
Filed: 2001-09-21
Abstract: A power line communication circuit (10) comprises a rectifier (20) connected to an a.c. power line utility source (12). The rectifier (20) draws power from the a.c. power source (12) and produces a low-frequency rectified d.c. voltage across its positive and negative output terminals with the negative output terminal (32) being referenced as a circuit ground. The rectified d.c. voltage signal is received by a voltage-to-current converter (38) connected to the positive output terminal (30) of the rectifier. The voltage-to-current converter (38) also receives a high-frequency a.c.-shaped communication input voltage signal from an external high-frequency a.c.-shaped communication signal generator. In response to the two input voltage signals, the voltage-to-current converter (38) generates an output current which contains a low frequency d.c. component from the rectified d.c. input voltage signal and a high frequency a.c.-shaped component from the a.c-shaped high frequency communication input voltage signal. The high frequency a.c.-shaped communication component is superimposed on the low frequency d.c. component to place communication data signals on the a.c. power line.

The invention is characterised in that it does not compri se degreasing means provided upstream of the coagulation-flocculation-decantati on device, the grease being removed from the water inside the coagulation- flocculation-decantation device itself without means for injecting air or an  equivalent gas.
Patent CA-2436451-A1 (CA)
Title: Liquid crystal display device
Inventor: IKEZAKI MITSURU
IPC: G09G3/36
Filed: 2001-12-25
Abstract: A liquid crystal display device requiring no flicker adjustment after manufactured. The liquid crystal display device is of IPS drive type. Just after the liquid crystal display device is turned on, there is an intial voltage component between a pixel electrode and a common electrode. The initial DC voltage component is considered to cause flicker. When the DC voltage component is automatically lowered to an allowable value in a predetermined time after the power is turned on, flicker adjustment is not required by changing the potential applied to the electrodes in the pixels. For this, it is necessary to lower the initial DC compositions sufficiently and to make a construction in which charge can migrate at a high speed in the liquid crystal panel. A punching-through compensation drive method is adopted as one technique of lowering the initial DC components. The construction of opposed substrates are made preferrable to facilitate the migration of charge therein.

Title: Coated paperboards and paperboard containers having improved tactile and bulk insulation properties
Inventor: SHANTON KENNETH J
IPC: D21H19/66
Filed: 2003-09-03
Abstract: An improved paperboard has been bulk enhanced by retaining a substantial portion of bulk-enhanced additives including expandable microspheres in a suitable distribution within the paperboard. The cellulosic paperboard web has an overall fiber weight (w) of at least 40 lbs. per 3000 square feet and, at a fiber density of 3, 4.5, 6.5, 7, 8.3 and 9 pounds per square foot ream at a fiberboard thickness of 0.001 inches, has a GM Taber stiffness of at least about 0.00246w2.63 grams-centimeter/fiber mat density1.63, and a GM tensile stiffness of at least about 615 + 13.18w pounds per inch.  The high retention of the bulk enhancing additives is believed to result from the incorporation of suitable retention aids. The resulting paperboard has better GM Taber stiffness values and GM tensile stiffness than prior art paperboards. The paperboard also has increased strain to failure and is able to be formed into suitable paperboard containers without loss of integrity.  The resulting containers have increased hold times when they contain hot or cold food or drink.

Patent CA-2446688-A1 (CA)
Inventor: THORPE RICHARD JOHN
IPC: G05B19/02
Filed: 2002-05-08
Abstract: Control of a multi-variable process involves multi-dimensional representation of the values (Qa-Qh) of the process variables according to individual coordinate axes (Xa-Xh), and response based on sets of values for the process-variables accumulated from multiple, earlier operations of the process. An acceptable range (UL-LL) for each process variable due to the current values of the other variables is defined from the accumulated values, and the existence of an alarm condition in which the current value (Qg) of a variable lies outside the range defined for it, is detected and displayed (UC) on the relevant axis (Xg). The change of the values (Qa, Qb) of one or more of the manipulatable variables (a-c) required to rectify the alarm condition is determined iteratively, and implemented by operator or automated response.
