Filed: 2001-05-25
Abstract: A cement float collar is disclosed that can be positioned downhole and used in a wellbore completion operation after drilling a wellbore with casing. A wellbore drilling and completion method is also disclosed. The cement float collar is made for pumping downhole and into engagement with a groove formed in the casing, called the profile nipple. As such, no restriction is needed in the casing for accepting or latching the float collar and the portion of casing including the groove can be installed at the start of the drilling operation. In addition, the profile nipple can be used to engage other drilling tools and, therefore, can already be in place when the final well depth (TD) is reached.

Title: Apparatus and method for suppressing tinnitus
Inventor: STYPULKOWSKI PAUL H
IPC: A61F11/08
Filed: 1989-11-21
Abstract: ABSTRACT OF THE DISCLOSURE           Method and apparatus for suppressing tinnitus by repositioning the basilar membrane so that the tectorial membrane does not chronically contact the stereocilia of the inner row of hair cells. A preferred mechanism involves the application of a pressure differential to the external ear canal. Preferably, the pressure differential is negative with respect to ambient. Alternatively, a positive pressure may be maintained in the external ear canal and, preferably, statically maintained. Alternative arrangements for repositioning the basilar membrane involve repositioning the ossicles and providing a middle ear pressure either with or without venting to the external ear canal.

Title: Process for stabilizing mine tailings
Inventor: NELSON WILLIAM E
IPC: B08B15/00
Filed: 1990-02-15
Abstract: ABSTRACT          This invention provides a reliable, long lasting, yet indefinite-lasting sealant for mine tailings and rock waste components.          Mining operations which involve large scale excavation and movement of soil or rock unavoidably lead to significant impacts on the surrounding natural environment.  The development and implementation of reliable environmental protection techniques can enhance both mining, activity and environmental maintenance.          One of the most damaging impacts of many mining operations is the exposure of minerals to the open air where they may become vulnerable to acidification and release harmful contaminants.  This is known as "acid mine drainage" which is the creation of acidic conditions through the exposure and oxidation of sulfide minerals at a mine site.  Sulfide minerals and associated acidity can be found in many mine components, including mine walls, waste rock and tailings from mill processing.  Acid mine drainage is reported at many types of precious-metal, base-metal and uranium mines.          Current control techniques attempt, (1) to neutralize the acidity through the addition of limestone or other neutralizing minerals and/or (2) to prevent the acidity and the entry of water and oxygen which cause sulfide oxidation. The former method is a control approach whereas the latter is more correctly a preventative approach.  Unfortunately, current technology for prevention is unreliable.  Sealants such as concrete and asphalt appear to be initially successful but become permeable through time due to fractures and crevices created during freeze-thaw and due to desiccation.

Abstract: METHOD AND APPARATUS FOR MEASURING WELLBORE    DIAMETER USING ELECTROMAGNETIC WAVES                                  ABSTRACT A method is proposed for determining the distance from an investigating device to the surface of a medium capable of supporting wave propagation. Ac-cording to the method, a propagatory wave is generated at a given location along the surface of said medium and spaced laterally therefrom. The propaga-tory wave is caused to enter the medium and to propagate in the medium. The phase of the propagating signal is detected at a pair of locations respectively spaced longitudinally along the surface of the medium by different distances from the transmitting location. An indication of the lateral spacing between the detecting means and the medium is determined in response to the phase information detected at the pair of locations.

Abstract: The protective device against an overheating, in particular by fire, of individual or batteries of pressure vessels (10) of a length (1) of at least 1.5 m serves for the storage and/or transportation of high- pressure gases. The pressure vessels (10) have at least one end cap (14) with a valve (18) or an end plug (20) with a melting plug (22) of an alloy melting at a low temperature. On at least one end cap (14) a pressure pipe (24), communicating constantly with the interior of a pressure vessel (10) branches off, which pressure pipe is led in axial direction (A) along at least a part of the pressure vessel (10). At intervals (a), essentially T-shaped fittings (26) are installed in the pressure pipe (24), which fittings have in their branching-off leg a melting plug (22) of an alloy melting at a low temperature. A blindly ending pressure pipe (24) is closed off by such a melting plug (22). The protective device is primarily used on pressure vessels of aluminium, in particular with a fibre-reinforced jacketing (12).
