Patent CA-2077220-A1 (CA)
Title: Steam box
Inventor: KOIVUKUNNAS PEKKA
IPC: D21G7/00
Filed: 1992-08-31
Abstract: The present publication discloses a steam box comprising means (4, 10, 13, 16) for distributing steam onto a web (1) being calendered, at least one valve (5, 6, 7) connected to said steam distributing means and capable of controlling the blowing of the steam onto the web (1) and elements (3, 25, 15, 16, 9) for feeding hot steam to the valve (5, 6, 7). The invention is based on having in each valve (5, 6, 7) at least three steam channels, namely an inlet channel (22) for feeding the steam to the valve, an outlet channel (23) of the, valve for feeding the steam onto the web (1) and a recirculation channel (24) for recirculating the steam, and a check element (20) for controlling and dividing the incoming steam flow from the inlet channel (22) between the outlet channel (23) and recirculation channel (24) of the valve, and a return pipe (27) connected to the recirculation channels (24) of the valves (5, 6, 7), capable of routing the steam directed to the recirculation channel (24) of the valve (5, 6, 7) to, e.g., the condensate return line of the steam distribution system. By virtue of such a circulation the valve can be kept warm even when no steam is directed via said valve, thus preventing the formation of droplets and their blowing onto the web.

Title: Biological system for degrading nitroaromatics in water and soils
Inventor: CRAWFORD DONALD L
IPC: C02F3/00
Filed: 1991-04-09
Abstract: Novel methods for biodegrading nitroaromatic compounds present as contaminants in soil or water using microorganisms are disclosed. Water is treatable directly; dry soil is first converted into a fluid medium by addition of water. The preferred method comprises two stages, each employing microorganisms: a fermentative stage, followed by an anaerobic stage. The fermentative stage is rapid, wherein an inoculum of aerobic and/or facultative microorganisms ferments a carbohydrate added to the fluid medium, exhausting the oxygen in the fluid medium and thereby inhibiting oxidative polymerization of amino by-products of the nitroaromatics. In the subsequent anaeobic stage, an inoculum of a mixed population of anaeorbic microorganisms completes the mineralization of the contaminant nitroaromatics, using the remaining carbohydrate as a carbon and energy source. Preferably, the carbohydrate is a starch and the aerobic and/or facultative microorganisms are amylolytic, which cleave the starch at a moderate rate throughout both stages, ensuring a sustained supply of metabolizabe carbohydrate.  The microorganisms are preferably selected to be resistant to the types and concentrations of nitroaromatics present as contaminants.

Title: Method and system for automatic modem protocol selection in a cellular communications system
Inventor: BRIGIDA DAVID J
IPC: H04W24/00
Filed: 1993-01-07
Abstract: A method and system are disclosed for automatically selecting an optimum modem protocol in a distributed data processing system which includes a modem which supports multiple protocols which is coupled to a cellular communications system. Known cellular communications systems generate a Received Signal Strength Indicator (RSSI) and a Service Access Tone (SAT) which may be utilized by a cellular telephone to determine the amplitude of a received signal and to optimize a path through the cellular communication system for voice communications. The Service Access Tone (SAT) is generally utilized to control the "hand off" of a communication session to a new cell and provides an indication of the quality of the existing path through the cellular communication system.  After initiating communication between a first modem and a second modem, the method and system of the present invention automatically determines the channel quality within the cellular communication system by utilizing the Received Signal Strength Indicator (RSSI) and the Service Access Tone (SAT). These signals are analyzed, in conjunction with the bit error rate of the dotting sequence transmitted by the answering modem, to achieve an indication of the quality of the cellular communications channel. In response to an analysis of these factors a particular protocol may be selected which is optimum for existing channel conditions.

Filed: 1994-10-14
Abstract: ABSTRACT OF THE DISCLOSURE   The present invention is concerned with a method for selectively removing antimony and bismuth from an impure sulphuric acid solution containing at least 50 g/L of acid and some concentration of ferric ion (for example copper refinery electrolyte), is disclosed. The method involves contacting the impure solution with a sufficient quantity of finely divided metallic copper so as to prereduce all ferric ion present in the solution to the ferrous oxidation state. The prereduced solution is then contacted with a chelating resin. The method avoids the deleterious loading of ferric iron onto the ion exchange resin and prevents the return of excessive amounts of chloride ion with the purified electrolyte.
