Title: Method for pollution emission reduction from glass melting furnace
Inventor: ALEXANDER JEFFERY C
IPC: B03C3/145
Filed: 1993-08-23
Abstract: A method for reducing pollution emissions from a glass melting furnace using electrostatic granular bed (EGB) technology is disclosed. In one embodiment, sorbent dust containing an alkaline earth metal material, e.g., calcium, is injected into a prereac-tor for reaction with furnace exhaust gases. A layer of calcium material forms over the granules. These granules are co-mingled with granules from an EGB filter which, over a period of time, retain a layer of low resistivity alkali metal salt. The resulting mix-ture of granules maintains a high resistivity and therefore prolongs the life of granules used in the EGB filter. In an alternative embodiment, the granules in the EGB filter are themselves formed from an alkaline earth metal material. The granules react with sulfur compounds in the exhaust gas and form a layer of alkaline earth metal sulfates and sulfites in the granules. Simultaneously alkali metal-containing particles are deposited on the granules. The accumulated layers of pollutants are easily removed by me-chanical agitation.

Patent CA-2156979-A1 (CA)
Inventor: STUBER URSULA
IPC: A47C9/00
Filed: 1995-08-25
Abstract: A tilted musician stool comprises a central column, a seat mounted at an upper end of the column and adapted to take on a series of orientations with respect thereto, and a base secured to a lower end of the column.  The upper end of the base defines a longitudinal central square opening which slidably receives the square column.  The position of the column and thus of the seat with respect to the base can be selectively varied.  The lower end of the base is enlarged and defines an annular peripheral rim extending in a plane.  The lower end of the base further includes a downwardly projecting central leg which is coaxial to the longitudinal axis of the stool. The lowermost end of the leg is located below the plane of the annular rim.  The stool is thus at rest supported on its leg and on a portion of the annular rim and in an unstable position.  The user of the stool can exert forces with his/her legs and pelvis to raise the complete rim above the ground such as the stool engages the ground only at its central leg, wherein the user sits in an ergonomic and anti-fatigue upright position.  If the user gradually decreases the application of the required forces to retain the rim away from the ground, the annular will eventually contact the ground, whereby the user will become aware that he/she has relaxed his/her posture and has thus moved away from the ergonomic position; the user can then take again the proper position by exerting forces so as to lift the annular rim from the ground.

Title: A method of protecting against neuron loss
Inventor: LANDFIELD PHILIP W
IPC: A61P25/28
Filed: 1994-07-14
Abstract: The present invention pertains to a method of protecting against neuron loss in a subject by administering a compound that protects against neuron loss by acting through a vitamin D receptor. Some of these compounds may prevent or retard neuron loss by regulating intraneuronal and/or peripheral calcium and phosphate levels. Other compounds of the invention act through a vitamin D receptor to protect against neuron loss through mechanisms not involving calcium or phosphate regulation. A preferred compound is a biologically active form of vitamin D, a precursor, metabolite, or analog of vitamin D. A preferred form of vitamin D is calcitriol. In another embodiment, the compound is a compound that acts by modulating the biological activity of vitamin D, a precursor, metabolite, or analog of vitamin D. For example, the compound may modulate the biological activity of the vitamin D compound by regulating the amount of the vitamin D compound which is available to protect against neuron loss or it may act by altering the ability of the vitamin D compound to protect against neuron loss. In an alternative embodiment, the compound is a compound that protects against neuron loss through a mechanism similar to that of the vitamin D compound but not involving a vitamin D receptor. The compound is administered to a subject in an amount and over a period of time effective to protect against neuron loss.

Title: Biotin-analog conjugated antibodies for positive cell selection and release
Inventor: AL-ABDALY FAHAD A
IPC: C07K16/28
Filed: 1994-09-08
Abstract: The invention provides a stable conjugate of a target cell binding protein, preferably an antibody, covalently linked to  a  biotin  analog moiety  for  use  in  positive  cell selection and release.            The invention also provides a method for forming a stable conjugate  of  an  antibody  and  a  biotin  analog  moiety comprising bringing an N-hydroxysuccinimide (NHS) ester of a biotin analog into reactive contact with an antibody in a medium with a pH of about 8 and at a temperature of about 2°-8°C.            The  invention  also  provides  methods  for  the  positive selection  of  target cells  from  a  heterogeneous  cell suspension.            One  method  involves  the  formation  within  the  cell suspension of a complex formed by the target cell bound to a primary antibody linked to a biotin analog moiety,  a secondary anti-biotin antibody bound to the biotin analog moiety and linked to a cell separation means.  The complex is separated from the heterogeneous cell suspension, then incubated with a competitive compound, preferably authentic biotin,  for which the secondary antibody has a higher affinity  than  it  has  for  the  biotin  analog.    The competitive compound displaces the biotin analog moiety from the binding site of the  secondary antibody,  thus releasing the target cells from the complex.   The cell separation means may then be separated from the target cells.            Another  method  involves   the   formation  within  the heterogeneous cell suspension of a complex formed by the target cell bound to a primary antibody linked to a biotin analog moiety and a form of avidin, which is bound to the biotin analog moiety.  The complex is separated from the heterogeneous cell suspension and then incubated with a competitive  compound,  preferably  authentic  biotin,  for which avidin has a higher affinity than it has for the biotin analog.   The competitive compound displaces the biotin analog moiety from the avidin binding site, thus releasing the target cells from the complex.  The avidin may then be separated from the target cells.            The invention also provides compositions of matter which are intermediate complexes  in the above methods.   One intermediate complex comprises  a cell  separation means bound to an anti-biotin antibody, which in turn is bound to a biotin analog moiety covalently linked to a target cell binding protein.   Another intermediate complex comprises avidin bound to a biotin analog moiety covalently linked to a target cell binding protein.
