Title: Method and apparatus for enhancing production of TIO2
Inventor: GEBBEN WALTER DAVID BRUCE
IPC: C01G1/02
Filed: 1994-11-22
Granted: 1997-05-22
Abstract: A method and apparatus for producing TiO2 by reacting O2 and TiCl4 in a reactor tube wherein pressure fluctuations in the flow of fluids through the reactor tube are sensed and output signals are generated proportional to the sensed pressure fluctuations. The flow of at least one of the TiCl4 or O2 is then varied through the reactor tube in response to predetermined pressure fluctuations so as to increase the efficiency of the reaction between TiCl4 and the O2. The efficiency of the reaction between O2 and TiCl4 in the reactor tube is achieved by a control apparatus operably connected to the reactor assembly which is capable of monitoring pressure fluctuations in TCl4 and O2 through the reactor assembly so that the flow of at least one of the TiCl4 or O2 can be varied in response to predetermined pressure fluctuations. The control apparatus includes a sensor assembly, a signal conditioning unit and a signal processing unit. <IMAGE>

Title: Continuous RBCOD measurement
Inventor: BRIDGER JOHN STEPHEN
IPC: G01N27/48
Filed: 1991-07-03
Granted: 1994-04-28
Abstract: The invention provides a method and apparatus for providing periodical measurements of the real-time readily bio-degradable chemical oxygen demand (RBCOD) of a wastewater stream. The apparatus includes a bio-reactor (1) having an inlet (6) for accepting a continuous feed from the stream and an overflow outlet (7), whereby a sample volume can be maintained within the reactor. A feed rate is chosen to ensure an hydraulic retention time (HRT) in the reactor sufficient for substantially complete oxidation of the readily biodegradable compounds in the feed. Air (2) is periodically passed through the sample volume for set periods and the oxygen up-take (OUR) is determined by measuring the dissolved oxygen content via a probe (3) during the air-off periods. An RBCOD value is then calculated for each OUR value. The invention may be used to monitor the performance of wastewater treatment plants.

Filed: 1998-06-30
Granted: 2001-11-15
Abstract: It has been discovered microparticles formed from natural or synthetic polymer with thicker walls have significantly enhanced echogenicity as compared with microparticles having thinner walls. The effect of wall thickness has been determined experimentally as well as inserted into a formula for use in predicting the optimum conditions. In the preferred embodiment, the polymers are synthetic biodegradable polymers and the wall thickness is between about 100 and 660 nm, although wall thicknesses from about 20 nm to in excess of 500 nm can be used. The microparticles are manufactured with a diameter suitable for the targeted tissue to be imaged, for example, with a diameter of between 0.5 and 8 microns for intravascular administration, and a diameter of between 0.5 and 5 mm for oral administration for imaging of the gastrointestinal tract or other lumens. Preferred polymers are polyhydroxy acids such as polylactic acid-co-glycolic acid, polylactide or polyglycolide, most preferably conjugated to polyethylene glycol or other materials inhibiting uptake by the reticuloendothelial system (RES). The microspheres may be used in a variety of ultrasound imaging applications including cardiology applications, blood perfusion applications as well as for organ and peripheral vein imaging.

Title: Screw spindle nut with ball bearings - has outer bearing race made from flanged spring steel rings
IPC: F16H25/22
Filed: 1969-02-19
Abstract: A screw spindle (2) has circular thread from to match the spherical bearing balls (4) which are located inside the spindle nut assembly (1). This type of spindle nut allows higher load application with smaller friction losses. The balls are retained in a cage (3) so that they stay inside the nut housing when it is removed from the spindle. The outer bearing race for the balls is produced by pairs of flanged spring steel rings (9, 10). Since their internal flanges are inclined relative to the spindle axis, each flange pair forms a V-shaped ball race. As the rings (9, 10) are made from spring steel, radial flexibility for the nut is obtained, thus allowing for tolerance variations on the spindle.

Title: Rotary piston sealing fillet - has radial holes extending to varying depths and located outside fillet longitudinal centre line
IPC: F01C21/08
Filed: 1972-07-11
Abstract: The radial sealing fillet is designed for use with rotary pistons. It has a number of radial holes running outwards from its under surface. These holes (3) extend to varying depths into the fillet (1), and lie, at least partly, outside the lengthways centre line of the fillet. This arrangement prevents undesired tipping movement of the sealing fillet, and is adequate under conditions when only single holes are arranged eccentrically.

Abstract: 1532848 Purifying proteins P G S LINDROOS 19 Nov 1976 [11 Dec 1975] 48376/76 Heading C3H  A method for separating iron compounds from the protein in a hemoglobin solution, comprises adding to said solution an organic solvent comprising ethanol in an amount such that the total ethanol content in the solution is at least 40% by volume, adjusting the pH of the liquid to a value lower than 4À5, whereby iron compounds in the solution are agglomerated, and thereafter separating the agglomerated iron compounds from the solution. The solution may be adjusted to a pH value which is less than 4À5 but greater than 2À5. Preferably the pH-value of the solution after agglomeration of the iron compounds is, before or after their separation, raised and wherein any fraction of blood protein precipitated thereby, with iron compounds included therein or adsorbed thereonto, is separated from the mixture. Before or after the agglomeration of iron compounds a minor quantity of broth of blood cells may be added to the solution and any flaky material of fragments of cell membrane formed thereby, together with iron compounds adsorbed thereonto, is then separated from the mixture. The organic solvent preferably includes a minor proportion of glycerin or ethylene glycol or methanol or acetone or ethylacetate or propanol or isopropanol or butanol. The iron compounds may be separated from the solution by centrifuging or a cyclone process or filtering or ultrafiltering or sedimenting or adsorption on to  voluminous or solid material, and the protein may be recovered from the solution by precipitation or adsorption on to solid or voluminous material or ultrafiltering or evaporation of the solution or drying or concentration of the solution by means of freezing.  The ethanol content in the solution after the agglomeration of iron compounds may be increased before or after their isolation and the fraction of blood protein precipitated thereby, together with any iron compounds included therein or adsorbed thereonto, may then be separated from the mixture. Before addition of ethanol to the solution and lowering of the pH of the solution, the solution is preferably cooled to a temperature of between zero and -20‹ C. and wherein this temperature is maintained during the entire further treatment.
