Abstract: Abstract of the Disclosure A  system  and method  for  improving the  seal integrity and useful life of tubing and casing strings fills the volume between the nose ends of facing tubing sections and the collar to which they are mutually joined with a temperature and corrosion resistant element having a smooth interior surface substantially flush with the inner diameter of the tubing or casing.  During makeup of each successive section of the drill string, a center fill tool including an expansible tubular element is seated below the coupling area to be self-retained, by the use of pressure expansion of a cylindrical surface.  A precise amount of a curable material is inserted into the volume bounded by the nose ends and the collars (the so-called "J area")  and while the material  is  still  flowable  the coupling is made up by threading in of the next tubular element.  When sufficient setting has taken place, which occurs quickly, a retrieving tool is lowered to grip the upper end of the insert which is configured internally to vent the pressurizing gas as upward force is exerted. Thus the center fill tool can be moved out of position and the string lowered into the well bore, the tool then being ready for makeup of the next succeeding coupling.

Granted: 1992-11-03
Abstract: Abstract of The Disclosure A firefighter's garment having a double wrist-let sleeve and cuff structure.  The garment has full length sleeves.  The garment, including the sleeves, has a plurality of layers:  an outer layer, which is a flame resistant layer, an intermediate layer, which is a moisture barrier layer, and an inner layer, which is a thermal barrier layer.  A cuff member of moisture barrier material is positioned at the end portion of each sleeve and extends directly from at least one of the layers.  A wristlet or seal member is encompassed by the cuff member and is adapted to snugly encompass the wrist of the firefighter who wears the garment. Another wristlet or seal member is positioned between the cuff member and the outer layer.  The wristlets or seal members are preferably of thermal barrier material. Thus, the sleeve and cuff structure protects the fire-fighter against movement of fluids and hot embers and other debris to the wrist and arm of the firefighter.

Abstract: Abstract A new method for fabricating a semiconductor device, e.g., a MOS or MES IC, as WELL as the resulting device, are disclosed. In accordance with the new method, a semiconductor device is formed, at least in part, by forming a material region which includes metal, e.g., elemental metal or a metal-containing compound, on a semiconductor substrate. One or more dopants are implanted into the material region, and the substrate is heated in order to diffuse the dopants out of the material region and into the substrate, thus forming a dopant-diffused substrate region, e.g., a source or drain. Significantly, the new method involves implant conditions which yield a material region-to-substrate specific contact resistance equal to or less than about 10-6.OMEGA.-cm2. In addition, the new method involves heating temperatures and heating times which yield a dopant-diffused substrate region having a depth, relative to the top of the material region, equal to or less than about 0.2 micrometers.

Title: Low-voltage source for narrow electron/ion beams
Inventor: FINK HANS-WERNER
IPC: H01J1/304
Filed: 1989-07-28
Granted: 1992-12-22
Abstract: ABSTRACT            This source for charged particles, comprises a sharply pointed tip (1) and an aperture (2) in a thin sheet of material.  If the point of tip (1) is made sharp enough, i.e., if it ends in a single atom or a triter of atoms, the electric field existing between the tip (1) and the aperture  (2)  will  cause  a  stream of electrons to be emitted from the tip (1), pass the aperture (2) and to continue as a beam (4)  of free electrons beyond said aperture (2).   The sheet (3) carrying the aperture (2) may, for example, be a carbon foil or a metallic foil, including gold.   The distance of the tip (1) from the aperture (2) is in the submicron range,  and so is the diameter of said aperture (2).  The distance is being held essentially constant by means of a feedback loop system. The divergence of the beam (4) is <2° .  If the source is operated in an ultra-high vacuum, the particle beam (4) will consist of free electrons, whereas, if the source is operated in a noble-gas atmosphere,  the beam (4) will consist of noble-gas ions.   Both, the electron beam, as well as the ion beam, contains particles of a very low frequency.

Abstract: For the analytical and preparative separation of the optical isomers of optically active alkanolamines into their optically pure antipodes a new resolution method is presented which involves an ester formation of the alkanolamines with optically pure and symmetrically O,O disubstituted (R,R)- or (S,S)-tartaric acids. The derivitization reactions are carried out in aprotic solvents and the primary and secondary functions are blocked via ion-pair formations with strong acids, e.g. dichloroacetic acid. The tartaric acid anhydrides are predominantly used as reagents but other ester formation methods are also practicable. The mixture of the diastereomeric alkanolamine tartaric acid monoesters are separable into their optically active and pure isomers by various chromotographic separation techniques, e.g. straight or reverse phase LC, but also by extraction methods e.g. Soxhlet extraction. The optically pure parent alkanolamine isomers can be obtained by ester hydrolysis, with high yield, from the optically pure fractions of the alkanolamine tartaric acid monoesters.
