Title: Method for arsenic removal from wastewater
Inventor: BREWSTER MICHAEL D
IPC: C02F9/00
Filed: 1993-02-11
Abstract: METHOD FOR ARSENIC REMOVAL FROM WASTEWATER            Abstract of the Disclosure A process and apparatus for removing arsenic from aqueous media is described.   The process in general utilizes  ferrous  ion provided by an electrochemical cell which is added to the aqueous media in a first step, followed by mild oxidizing conditions generated by the addition of hydrogen peroxide.  The ferrous ion then  forms  an  hydroxide  which  is  oxidized  to  an oxyferric oxide  and  the  arsenic  present  at  a  +3 oxidation state is oxidized to a +5 state whereupon the oxyacid  complexes  with  the  oxyferric  oxide.    A precipitate then is formed which consists of ferric arsenate,  and  the  hydroxy  ferric  oxide  -  oxyacid complex.   Heavy metals may also be removed by the process.

IPC: B60R21/01
Filed: 1993-02-18
Abstract: An air bag system able to inflate an air bag at an appropriate time, corresponding to different collision modes, with a simplified construction.  The system is provided with a longitudinal acceleration sensor and an acceleration level computing means which computes the degree of acceleration.  A rate of change computing means computes the rate of change of the acceleration and detects a characteristic of the rate of change, and sends the resultant data to a first judging means.  A first judging means detects the presence of a collision based on the degree of the acceleration and the characteristic of the rate of change of the acceleration.  A second judging means is provided in order to detect the presence of a collision based on the acceleration.  An air bag driving signal outputting means outputs an air bag driving signal based on the judgments made by the first and the second judging means.

Title: Multiple promoter baculovirus expression system and defective particle production
Inventor: OKER-BLOM CHRISTIAN E G
IPC: A61K39/00
Filed: 1991-09-17
Abstract: The invention describes the construction of a genetically engineered virus or virus hybrid (e.g. animal or human pathogen) which is not capable of replicating itself but is essentially identical to the authentic pathogen in terms of structure and antigenicity. This baculovirus is constructed such that the non-structural viral genes are truncated, mutated or both and are located 3' and directly under the control of an early baculovirus gene promoter and the structural viral genes are located 3' and directly under the control of a late baculovirus gene promoter.  This genetically baculovirus is therefore capable of temporal regulation and successive synthesis of non-structural proteins.  This invention enables the design and construction of a virus particle or virus hybrid with specific antigenic properties which further allows for the safe and inexpensive production of vaccines and diagnostics.

Title: Mat faced duct board and method of manufacture thereof
Inventor: NOONAN PATRICK M
IPC: E04F17/04
Filed: 1994-07-27
Abstract: An improved fiber glass air duct board is provided for the manufacture of insulated air ducts. The board features an air surface facing means providing a smoother interior surface that engages the air flowing through the duct. The smoother surface afforded by the facing reduces friction loss of the air flowing through the ducts as well as reduces the accumulation of dust and dirt within the ducts. Further, the facing provides an additional means for treating the interior of the ducts with biocides to reduce the likelihood of microorganisms surviving in the interior walls of the duct. In the preferred method of manufacturing the duct made in accordance with the present invention, the surface facing is applied to the upper surface of the fiber glass before it is transferred into the flighted oven.
