Title: Electrolytic process for producing chlorine dioxide
Inventor: LIPSZTAJN MAREK
IPC: C25B1/26
Filed: 1998-10-15
Abstract: A process for converting in a single pass an aqueous alkaline pH, alkali metal chlorite solution into an aqueous chlorine dioxide-containing solution that involves the combination of (1) using an electrochemical acidification cell to lower the pH value of the aqueous alkali metal chlorite feed before it enters the anode compartment of an electrochemical oxidation cell where the chlorite is converted to chlorine dioxide with (2) using an anolyte flow pattern where the anolyte passes through a porous, high surface area electrode.  This process results in a substantially improved conversion efficiency per pass.

Title: Transmission method, transmitter and receiver for variable length frames
Inventor: NAKA NOBUHIKO
IPC: H04J3/06
Filed: 1998-05-15
Abstract: A variable length frame transmission method making it possible to accurately and easily establish synchronism at the receiver side without redundancy of system under an environment in which a code error easily occurs.      In a transmitter, a variable length frame division section 1 divides a variable length frame f into code strings f1 and f2 having a length ratio of 1:1. A first synchronization flag addition section 3-1 adds a synchronization flag S1 to the head of the code string f1 and a second synchronization flag addition section 3-2 adds a synchronization flag S2 to the head of the code string f2.      The synchronization flags have contents different from each other, but they have the same length. Code strings having synchronization flags are multiplexed by a changeover switch 4 and formed into a variable length frame. A series of variable length frames obtained from the changeover switch 4 are transmitted to a receiver as serial data. In the receiver, the start and end points of each frame is obtained based on the position of each synchronization flag in the serial data.

Title: Substituted sulfonamides as selective .beta.3 agonists for the treatment of diabetes and obesity
Inventor: OK HYUN
IPC: A61P3/10
Filed: 1997-07-21
Abstract: Substituted sulfonamides are selective .beta.3 adrenergic receptor agonists with very little .beta.1 and .beta.2 adrenergic receptor activity and as such the compounds are capable of increasing lipolysis and energy expenditure in cells. The compounds thus have potent activity in the treatment of Type II  diabetes and obesity. The compounds can also be used to lower triglyceride levels and cholesterol levels or raise high density lipoprotein levels or to decrease gut motility. In addition, the compounds can be used as reduced neurogenic inflammation or as antidepressant agents. The compounds are prepared by coupling an aminoalkylphenyl-sulfonamide with an appropriately substituted epoxide. Compositions and methods for the use of the compounds in the treatment of diabetes and obesity and for lowering triglyceride levels and cholesterol levels or raising high density lipoprotein levels or for increasing gut motility are also disclosed.

Patent CA-2273447-A1 (CA)
Inventor: CRESSWELL MARK
IPC: A01C1/00
Filed: 1999-06-02
Abstract: A liquid application unit for use on air seeders is provided which is cost-effective, has low maintenance and is highly reliable. This unit permits farmers to apply liquid substances, i.e. seed treatment substances to particulate material, namely seeds, just prior to the seed being inserted into the soil. The system uses an auger having two different pitches of flighting and/or different diameter flighting such that the volume available in between pitches of the flighting on the portion of the auger outboard of the orifice is greater than the volume available between the pitches inboard of the orifice. Chemicals are applied downstream of a sump area where the auger has either a larger pitch or larger diameter such that the volume available to the seed in the downstream area of the sump is greater. This will allow for better mixing action and minimize any effects on metering accuracy caused by build-up of chemicals on the flighting. In this device seed and chemicals are mixed by the rotation of the auger flighting within its cylinder.

Inventor: KIM KIHONG
IPC: H04B10/67
Filed: 1999-06-22
Abstract: The present invention provides an improved optical frequency demodulation technique for extracting overhead information from an optical channel signal carrying both high bit rate payload and low rate overhead data. The invention makes use of asymmetrical Mach-Zehnder interferometry (AMZI) in an optical frequency demodulator to efficiently extract the overhead information from the optical channel signal by frequency discrimination without necessitating a complete demodulation of the optical channel signal. By comparison to existing demodulation schemes, the invention provides an all-optical low cost, high gain technique for recovering the overhead data which improves the payload signal-to-noise ratio and enhance performance.
