Title: Composite structural components for outdoor use
Inventor: MULLETT DONALD H
IPC: E02B3/06
Filed: 1998-07-14
Abstract: A structure according to the invention comprises a series of interconnected structural members. The structural members, such as panels, are made of a composition comprising as its first essential ingredient a cured (cross-linked) resin having sufficient strength when filled as described below to support weights up to about 700 pounds without significant buckling, but which has sufficient resilience to flex and rebound from impacts such as low speed collisions with small boats or dropping of heavy human-carried objects without cracking or breaking.  The cured resin matrix contains a first filler consisting essentially of inorganic particles effective to improve the impact resistance and flame resistance of the structure, and an amount of a second filler consisting essentially of fibers effective to enhance the rigidity of the structure and reduce crack propagation therein.  An optional third filler consisting essentially of plastic microspheres may be added in an amount effective to reduce the weight of the panel by at least 10 % without significantly affecting the other essential properties of the cross-linked resin and first and second fillers, namely flexural strength, flame resistance, impact resistance, rigidity, resistance to crack propagation, and resistance to outdoor environments, particularly marine environments.  Piers and docks made from panels of the composite of the invention provide superior performance as compared to conventional materials used to build such structures.

Title: Self-aligning, minimal self-torque golf clubs
Inventor: TOM LEUNG
IPC: A63B53/04
Filed: 1998-09-15
Abstract: A self aligning, low or no self-torque club that is both statically and dynamically balanced is provided which is less prone to deleterious effects during its approach to and in the course of striking the ball and which enables the club head to be more square at the point of impact more often. Static balance is achieved by ensuring the longitudinal axis of the shaft intersects the line between the geometric center of the club face and the center of gravity of the club head. The club is self-aligning because the center of gravity naturally follows the shaft, the point of application of force on the club head, and since the shaft and center of gravity are in line with the center of the club face, the possibility of striking the ball with the club face square increases. By providing a symmetrical and, preferably elliptical face, forces due to air resistance act equally on both sides of the face with respect to the shaft further aligning the club face with the swing path of the club head. The club head may also be provided with a series of convergent longitudinal channels in the direction of air flow over the club to further align the club head. The channels serve to stabilize the club head during downswing and move the center of pressure toward the rear of the club and as far behind the axis of the shaft as possible and, preferably, in-line with the center of gravity and the club face. The symmetrical nature of the club head permits, in one embodiment, the same club head to be used for right- or left-handed golfers. Also provided is a set of clubs according to the invention, which due to their similar static and dynamic balance and similar shape and configuration, provide a similar feel and play throughout the entire range of lofts.

Title: Ion transfer from multipole ion guides into multipole ion guides and ion traps
Inventor: GULCICEK EROL
IPC: H01J49/00
Filed: 1997-05-14
Abstract: A multipole ion guide is configured to improve the transmission efficiency of ions which traverse the length of one guide (7) and enter either another multipole ion guide such as a quadrupole mass analyser (14) or a three-dimensional ion trap (64). The ion transfer multipole ion guide radial dimensions are reduced such that the pole assembly (30) and an appropriately shaped exit lens (31) can be positioned within a portion of the internal space defined by the larger radius second multipole ion guide poles (43). Ions exiting the first ion guide of reduced size find themselves inside the second ion guide close to the centerline (41).  In this manner, ions can be efficiently transferred from one ion guide to another, even for those ions with low kinetic energies. In a second embodiment of the invention, the exit region of a multipole ion guide (50) is configured such that the multipole ion guide poles can be extended into a counterbore (65) of a three-dimensional ion trap end cap electrode (64). With this configuration, ions (including those with low kinetic energies) can be transferred into a three-dimensional ion trap with increased trapping efficiency.

Title: Nuclear magnetic resonance logging with azimuthal resolution
Inventor: POITZSCH MARTIN E
IPC: E21B49/00
Filed: 1999-05-04
Abstract: The present invention relates generally to an apparatus and method for obtaining an azimuthally resolved nuclear magnetic resonance measurement of an earth formation traversed by a borehole. The measurement can be made while drilling or using a wireline tool. A receiving rf antenna having a non-axisymmetric response pattern is used to obtain the azimuthally resolved nuclear magnetic resonance measurement. The antenna employs axial currents which excite an azimuthally oriented rf magnetic field.      For this situation, the static magnetic field is either radial or axial in its orientation. The antenna generates a relatively long, in axial extent, region of generally uniform static field magnitude and polarization in the formation. The present invention facilitates low profile antenna configurations that can permit dispensing with the reduction of the inner diameter of the drill collar at the rf antenna location.
