Abstract: A method for logging a subsurface formation includes acquiring neutron capture data using a pulsed neutron tool at a plurality of locations along a borehole penetrating the subsurface formation, wherein the plurality of locations include a formation zone that contains water; comparing an apparent water salinity or an apparent water sigma value estimated from the neutron capture data acquired in the formation zone that contains water with a water salinity or water sigma value of a water sample from the subsurface formation to produce a calibration parameter for the neutron capture data; and correcting the neutron capture data, based on the calibration parameter, to produce corrected neutron capture data. The method may further include determining a water saturation from the corrected neutron capture data.

Abstract: A method and apparatus for checking/updating existing software on a user's computer utilizes a graphical user interface (GUI). The GUI enables the user, without knowing what software exists on the computer, to download a text file from a remote server and check whether the software on the remote server is contained on the user's computer. The user can also download and automatically install a new or updated program via the GUI.

Abstract: A software architecture for a personal computer enables control of an attached television set as a graphic output device, where the software architecture includes a dynamically linked library storing executable library routines that can be called by a computer system routine across an application programming interface, and a hardware extraction layer having hardware-specific routines that are called by a selected library routine to perform a specific hardware operation. The hardware-specific routines control operation of a graphics core configured to control the television set, for example by detecting whether the television set is attached to thecomputer system. Additional operations supported by the dynamically linked library include automatically adjusting the size and resolution of Windows (or portions thereof) output to the television set.

Abstract: Disclosed are novel circular DNA plasmids useful as vectors in recombinant methods to secure high levels of E.coli expression of exogenous genes. Plasmids of the invention comprise discrete DNA sequences operative to: (1) confer upon the plasmid the capacity for autonomous replication in a host cell; (2) control autonomous plasmid replication in relation to the temperature at which host cell cultures are maintained; (3) stabilize maintenance of the plasmid in host cell populations; (4) direct synthesis of a protein product indicative of plasmid maintenance in a host cell population; (5) provide, in series, a plurality of restriction endonuclease recognition sites, unique to the plasmid and facilitative of exogenous gene DNA sequence insertion; and (6) terminate mRNA transcription of adjacent DNA sequences and situated so as to terminate transcription of exogenous gene sequences inserted within the plasmid at said unique restriction endonuclease restriction sites.

Abstract: Methods and apparatus are described for estimating parameters, such as slowness and attenuation, of composite acoustic waves obtained in the course of sonic logging of formations traversed by a borehole. Sonic energy is sensed arriving at a plurality of points spaced vertically along the borehole after refraction, reflection and direct transmission through and along the formations. A window is established of predetermined length and moveout and the composite waves are multiplied by the window. A Fourier transform is obtained of the windowed data and the data are simultaneously analyzed to obtain an estimate of the parameters. The procedure is repeated for different window moveouts and index positions along the composite waves. The analysis is performed at each window position and moveout to obtain the best estimate of the parameters.

Abstract: An arbor for a rotary cutting tool which includes an elongated cylindrical shank that has an axial bore formed therethrough. The upper end of the shank is adapted to be attached to the drive spindle of an electric motor. The arbor shaft is slidably mounted in a carrier sleeve which is rotatable with the arbor shank which is retained against axial movement by a mounting means. An annular cutter is attached to the lower end of the arbor shank and a pilot ejector member is slidably mounted therein. The pilot ejector member is retained in the normal at rest position by a spring which has its upper end mounted in a bore in a piston that is attached to the carrier sleeve. The lower end of the spring engages a plunger member which maintains the pilot ejector member in its initial and other operative positions.

Abstract: A grindstone type of cylinder ridge remover to be used in conjunction with an electric drill for removing the ridge on the cylinder walls of piston type engines. The plate body of the cylinder ridge grinder rests on the top of the cylinder wall and is rotated by hand around the top of the cylinder wall, while an electric drill turns a grindstone by way of a shaft compatable to the chuck of the electric drill thus grinding away the ridge very effectively and very easily. The distance between the bottom of the body plate edge and the bottom of the grindstone, the depth into the cylinder which is to be ground, is regulated very exactly by an outside threaded sleeve bearing in complete control of the grindstone shaft being screwed up and down inside a threaded hub fixed to the body plate. The grinding depth position is locked by a thumb screw thru the hub side wall and against the outside of the sleeve bearing.

Abstract: A pole type pruner with an enclosed blade type construction whereby the blade is supported from the sides thru the whole cutting cycle so a thinner blade can be used for easier cutting and less distortion to the wood and bark. This distortion is further reduced by a more choke type, more confining type cutting method, and because regardless of tree limb direction or position the cutting angle of the blade can be directed nearly perpendicular to the limb due to the use of a pole section angle changing box. A pruning saw, one end pivoted to the end of the cutter blade handle, sheathed when desired, being used as part of the cutter blade pull system makes the saw always conveniently available to be pivoted to proper angle of saw direction and clamped to the cutter blade in this position for saw pruning and yet eliminates an awkward outward projection when it's not used for saw pruning. The twist type of blade return coil spring used also reduces any awkward projection.
