Title: Process and apparatus for the treatment of carbon dioxide with carbonic anhydrase
Inventor: BLAIS REJEAN
IPC: C01B32/50
Filed: 1998-06-02
Abstract: A process is disclosed for the extraction, production and purification of carbon dioxide gas. The process may also be employed for the production of aqueous and/or organic solutions of bicarbonate ions using a precursor feed stream of gas containing carbon dioxide. The process consists of the countercurrent flushing of a packed tower-type bioreactor with gas containing carbon dioxide and a liquid solvent. The bioreactor contains carbonic anhydrase covalently bound to an inert inorganic support. The carbon dioxide of the gaseous phase diffuses into the liquid phase. The immobilized carbonic anhydrase catalyses the hydration of the carbon dioxide which forms hydrogen and bicarbonate ions. The solution of ions may be employed directly or, alternatively, subjected to an ion-exchange resin to immobilize the bicarbonate ions. The aqueous solution of hydrogen and bicarbonate ions may also be recirculated into a second identical bioreactor, wherein they are catalytically converted to water and carbon dioxide.

A processor (25) measures characteristics such as the amplitude and/or delay of the reflected signal to determine the type of environment in which the communication device (20) is located. The volume of the alert sound is then adjusted based on the type of environment indicted by the characteristics of the reflected signal. For example, if the characteristics indicate a closed environment such as a brief case, the volume is adjusted to a high level, and if the characteristics indicate an open environment such as a desk top, the volume is adjusted to a low level.
Patent CA-2303995-A1 (CA)
Inventor: MOMBOURQUETTE IVAN G
IPC: E21B19/22
Filed: 2000-04-05
Abstract: The bottom end of a coil tubing string is secured to the bottom end of a primary tubing string at ground surface. Usually the primary tubing string will be of larger diameter and is therefore stronger and stiffer than the coil tubing string. The strings are secured together with a locking assembly. This assembly comprises two interlocking members, one connected with each string. One of the interlocking members is meltable when exposed to elevated temperature. The primary tubing string and the coil tubing string are run together into the desired position in the wellbore. The primary tubing string acts to drag the coil tubing string along with it. Heat is then used to melt the interlocking member so that the strings can be separated. The heat can be provided by circulating steam or hot water or oil down to the assembly. Alternatively the downhole formation temperature may be sufficient to induce melting. Once separated, each string can be pulled or moved independently. 10

Abstract: A level measurement device for measuring the level of material inside of a vessel which includes a conductive element, a signal generating unit and a receiving unit. The conductive element does not come into direct contact with the material being measured. The signal generating unit generates measurement signals which are transmitted along the conductive element. Each of the measurement signals produces an electromagnetic field which travels along the conductive element and is reflected when it reaches the surface of material in the vessel. The reflected electromagnetic field produces an echo signal which travels along said conductive element to the receiving unit. The receiving unit receives the echo signal and determines the level of material in the vessel. The conductive element can be located outside of the vessel. The level measurement device can also include a protective shield which substantially surrounds the sides of the conductive element to prevent interfering radiation from interfering with the signals transmitted and reflected along the conductive element.
