Abstract: CONVERSION OF CYCLIC POLYCARBONATE OLIGOMERS TO LINEAR POLYCARBONATES  INITIATED BY PHOSPHINE-DISULFIDE   PRODUCT OR PRECURSOR THEREOF                     ABSTRACT Cyclic polycarbonate oligomers are polymerized to linear polycarbonates by the action of a salt prepared by the reaction of a triarylphosphine or triaryl phosphite with an organic disulfide, preferably an aryl disulfide. The reactants which form the salt may be incorporated in the cyclic polycarbonate composition, and interreact when the composition is heated to form the active initiating species.

Title: Method and apparatus for generating phosphine
Inventor: BANKS HENRY J
IPC: A23B9/00
Filed: 1991-06-21
Abstract: Phosphine is generated by the reaction of water with a metal phosphide formulation. In one embodiment, the formulation is within a housing (10) closed by a membrane (12) which is permeable to water and phosphine. A water-containing gas flows across the membrane and water from the gas permeates into the housing to react with the phosphide, producing phosphine which also permeates through the membrane to enter the gas flow. Two membranes (12A, 12B) may be used to close the housing, one permeable to water, the other permeable to phosphine. A blanking plate (17) and phosphine absorber (18) may be included to control the phosphine production. In a second embodiment, pellets of a phosphide formulation are transferred, periodically, from a hopper (23) to a chamber (24) containing water. The transfer is effected by a disc member (25) mounted below the hopper and above the chamber. The disc member has at least one aperture in it, within which pellets are transported from the hopper outlet to an inlet port of the chamber. Control of the phosphine production is supplemented by varying the water temperature and by using a safety arrangement adapted to supply a purge gas to the generator. The safety arrangement utilises a reservoir (73) of the purge gas (usually dry air, nitrogen or carbon dioxide) at high pressure, established prior to the operation of the phosphine generator. If the electrical power supply to the generator fails, or if the gas pressure or the phosphine concentration in the generator is too high, a valve (78) opens to let the purge gas flow from the reservoir into the generator.

Title: A method for treating exhaust gas and an apparatus therefor
Inventor: IZUMO MASANORI
IPC: B01D46/24
Filed: 1992-09-03
Abstract: ABSTRACT    In the invention, powdery adsorbent is mixed with an exhaust gas (G) including fine particles and a poisonous/nasty smell gas in gas pipelines (9A, 9B), thereby the adherence of the fine particles to powdery adsorbent and the adsorption of nasty smell gas with the powdery adsorbent are performed.    The powdery adsorbent with the fine particles and poisonous/nasty smell gas is fed to dust collectors (14A, 15A), where the exhaust gas is separated from the powdery adsorbent and is purified.    The separated powdery adsorbent comes in contact with hot blast at high temperature, or is indirectly heated in a pipeline (12B), thereby the adsorbed poisonous/nasty smell gas is desorbed by heating treatment.    Further, a part of or all of the desorbed powdery adsorbent comes in contact with hot blast at higher temperature than the above mentioned temperature, or is indirectly heated in a pipeline (12C), thereby the fine particles adhered to the powdery adsorbent are thermally decomposed by heating treatment.    In this way, the powdery adsorbent are regenerated, is returned to the gas pipeline (9B) through a pipeline (12E) and is mixed with the exhaust gas (G)in order to be reused.

Title: Monoclonal antibodies directed against ndp-kinase
Inventor: PULIDO-CEJUDO GABRIEL
IPC: C12N5/18
Filed: 1993-10-15
Abstract: A monoclonal antibody against cytosolic nucleoside diphosphate kinase (NDP-kinase: EC 2.7.4.6) from HL60 cells has been produced. The monoclonal antibody solely recognizes the active oligomeric form of NDP-kinase and does not inhibit NDP-kinase activity. Reduction and alkylation of NDP-kinase oligomer performed under denaturing conditions fully destroyed the antigenic site recognized by the monoclonal antibody.      Western blot analysis after non-denaturing polyacrylamide gel electrophoresis (PAGE) revealed that a single protein oligomer is recognized by the MAb. The protein band showed the same electrophoretic mobility of pure cytosolic NDP-kinase detected by a specific NDP-kinase enzymic staining assay performed after nondenaturing PAGE. Collectively, the results suggest that the MAb recognizes the native form of NDP-kinase.      Searching for the reactivity of the MAb against membrane-bound NDP-kinase it was found that the MAb selectively reacts with a cell-membrane component of monocytes (93%), granulocytes (97%) and 14% of lymphocytes. Two color immunofluorescence showed that the MAb reacted only with CD19+ B cells (93% of CD19+ B cells), which suggest that NDP-kinase may play an important role in normal B lymphocyte function.

Title: Bungee jumping and catapulting apparatus
Inventor: AREL RICHARD
IPC: E06C5/04

Abstract: A ladder can be raised to a steep inclined position and a user can jump off a jumping platform carried by the top end of the ladder; the user is connected to a bungee cord which is attached to a non-elastic cable trained on a pulley disposed above the jumping platform and connected to a system to pay-out and retrieve the cable and operated by a double-acting hydraulic cylinder which can positively block the top end of the bungee cord at any desired level.  Blocking is also automatically effected whenever the hydraulic pressure falls below a predetermined minimum.  A catapulting arrangement is also provided to hurl the user up in the air.  The cable pay-out and retrieving system serves to stretch the bungee cord to catapult  and  to  lower  the  jumper  to  the  surface  upon completion of the jump or catapult.  The ladder is made of modular sections which can be folded into a transport mode.          The ladder and accessories are mounted on a roadable wheeled platform for transport to and erection in different sites.

Abstract: ABSTRACT OF THE DISCLOSURE         Soil comprising small soil particles, clay and silt particles,  humus,  fine vegetation,  and contaminated with soluble or insoluble radioactive species is treated by first introducing  an  aqueous  extracting  solution  comprising  a mixture of sodium and potassium carbonate (or bicarbonate), or ammonium carbonate  (or bicarbonate)  into the soil to solubilize and disperse the radioactive species into solution. The extracting solution has a pH greater than or equal to about 7.5.  Contaminated fine vegetation then is separated from the soil and extracting solution.  Next, an acid like hydrochloric acid is introduced into the soil.  The acid is added in an  amount  sufficient  to  lower  the  pH  of  the extracting solution at which point desirable organic material will  substantially  precipitate  or  coagulate  from  the extracting solution.  The cleansed soil particles, including organic matter, is separated from the contaminated extracting solution.   Radioactive species are then removed from the extracting solution, which then may be reused.

Abstract: An apparatus and method for automatically adjusting the control parameters of a self tuning controller used to regulate a process having a measured process variable signal. Using the measured process variable signal, an error signal representing a closed-loop response of the process to an upset condition is generated. Local extrema of the error signal is measured and three successive amplitude values are selected to produce measured decay and overshoot characteristics of the error signal. The three successive amplitude values are selected such that the measured decay characteristic is greater than the overshoot characteristic. Based on the measured decay and overshoot characteristics at least one of the control parameters of the controller is automatically adjusted to improve the difference between one of the measured characteristics and a target characteristic.
