Filed: 1998-02-19
Abstract: A process is provided for treating a water to reduce its hardness by performing a series of sequential stages including a primary chemical reaction stage, a secondary chemical reaction stage and a scale removal stage. The primary chemical reaction stage includes the steps of adding a first hydroxide ion donor in the form of lime to an initial water having an initial hardness and reacting the first hydroxide ion donor to form a first portion of a scale and anintermediate water having an intermediate hardness substantially less than the initial hardness. The secondary chemical reaction stage includes the steps of adding a second hydroxide ion donor in the form of caustic to the intermediate water and reacting the second hydroxide ion donor to form a second portion of the scale and a product water having a product hardness substantially less than the intermediate hardness. The reduction contribution of the primary chemical reaction stage to total hardness reduction is substantially greater than the reduction contribution of the secondary chemical reaction stage. The scale removal stage includes the steps of separating the scale from the product water to form a sludge and disposing the sludge.

Title: Packaging machine and method
Inventor: LERNER BERNARD
IPC: B65B43/28
Filed: 1993-08-06
Abstract: An improved packaging machine that has improved features for feeding a web in the form of a continuous chain of bags through the machine while helping maintain the web in proper alignment and proper tension, and having additional features for improved loading of the bags. The improved web feed includes a dancer assembly equipped with a pair of nips that are driven at speeds responsive to the rate of web travel through the machine so that tension between a web supply and the dancer nips is isolated from the downstream portions of the web. A web feed mechanism which automatically threads the web through baggers is also provided. The web feed mechanism includes elastic belts which fractionally grip the web to isolate the tension in the section between the dancer nips and the belts from the tension of the web feed mechanism.      Nips adjacent the load station and at the downstream end of the web feed mechanism have surface speeds exceeding the surface speed of the belts to maintain tension on the web through the web feed mechanism and effect a slight pre-opening of the bags before they are delivered to the load station.  Other features include a cantilevered support of the web supply and bagger, a bagger support which functions as a plenum, an improved dancer assembly, and improved application of compressed air for bag opening.
Patent CA-2244859-A1 (CA)
Inventor: GAFFNEY ANNE
IPC: C07D301/10
Filed: 1997-01-28
Abstract: Propylene is converted to propylene oxide in a vapor phase oxidation process employing a silver catalyst supported on an alkaline earth metal carbonate and containing both a potassium salt such as potassium nitrate and a molybdenum promoter. The potassium salt and the molybdenum promoter may be simulatneously supplied by the use of a potassium salt of a molybdenum oxyanion. The efficiency of the process is greatly enhanced through the simultaneous inclusion of carbon dioxide and an organic halide in the feedstream. The feedstream need not contain a nitrogen oxide species such as NO to attain high propylene oxide selectivity.

Patent CA-2254574-A1 (CA)
Inventor: PALMER FRED L
IPC: H05B41/24
Filed: 1998-11-27
Abstract: An electrodeless high intensity discharge lamp with a lamp fill material including gallium iodide has been found to be more efficient in generating light in general, and more efficient in generating blue light. The very small size of the lamp, in combination with the high intensity in a relatively narrow blue spectral range make the lamp particularly useful in supplying blue light to a fiber optic. The relative efficiency of the lamp increases its value. In combination, the lamp provides a useful, efficient source of blue light as an input source for optical fiber, and other systems for medical and other processes using blue light as a process element.

Patent CA-2255950-A1 (CA)
Inventor: KOENIG JACQUES
IPC: C01C1/04
Filed: 1998-04-07
Abstract: Ammonia production is increased in an ammonia plant having a primary reformer, a secondary reformer and an air compressor, where the primary reformer and/or the air compressor is operating at its maximum capacity, without investing to expand the capacity of either. A portion of the feed can bypass the primary reformer and enter the secondary reformer directly. Oxygen and nitrogen streams are added separately and independently to form an ammonia synthesis feed gas. Methane concentration in the outlet stream from the secondary reformer is controlled by manipulating the oxygen stream. Nitrogen concentration or a H2:N2 ratio in the ammonia converter feed gas is controlled by manipulating the nitrogen stream.

Abstract: A video memory system for storing ATSC video image data is configured as three channels, each channel having two banks and each bank including a plurality of memory rows. The exemplary memory system includes a buffer area for holding bit-stream data and six field buffer areas. The field buffer areas are arranged in pairs to form a three frame buffer areas, such that the buffer areas for the two fields in a given frame are allocated in respectively different banks. The video memory system includes an output memory controller which receives macroblocks of decoded image data and divides the received macroblocks into respective upper and lower half macroblocks, the upper half macroblock being stored in one field buffer of the frame and the lower half macroblock being stored in the other field buffer of the frame. In addition, the output memory controller stores the luminance and chrominance components of the half macroblocks in respectively different channels of the memory device and the channel assignment is changed from one half macroblock to the next. The memory system also includes an input memory controller which retrieves reference half macroblocks from the memory. The input memory controller is coupled to first and second address generators which operate concurrently to address image data in respectively different channels, banks and memory rows so that, when a reference half macroblock which includes components from two or more stored half macroblocks is retrieved, the memory read operations are overlapped.

IPC: A61K51/08
Filed: 1997-12-01
Abstract: The invention is a radiolabelled ligand for introducing an Auger electron emitting radionuclide into the nucleus of a cancer cell. The ligand binds selectively to a cell surface receptor that is unique to a cancer cell or which is overexpressed on a cancer cell. An Auger electron emitting radionuclide is bonded to the ligand either directly or by means of a chelator. The radiolabelled ligand is internalized by the cell upon binding to the receptor, and a sufficient portion of the ligands so internalized are transported to the nucleus to provide a lethal dose of radiation to it.
