Title: Microlenses for coupling optical fibers to elliptical light beams
Inventor: PRESBY HERMAN MELVIN
IPC: G02B6/42
Filed: 1992-12-16
Granted: 1999-02-23
Abstract: An asymmetric hyperbolic microlens on the end of a single-mode optical fiber enhances the fiber's coupling to elliptical laser beams. The lenses, with controlled eccentricity ratios, are made by micromachining the end of the fiber with a pulsed CO2 laser as the fiber is directed, preferably by computer control, about the focused laser beam. Coupling effiencies of 90 percent (-0.75 dB) have been realized with single transverse mode transverse mode lasers at a wavelength of 0.98 µm having an approximately 3 to 1 beam ellipticity. With multimode lasers at 1,48 µm having similar elliptical beams, the asymmetric lenses demonstrate an almost 2 dB increase in coupling efficiency over symmetric hyperbolic microlenses. Such lasers are useful to pump erbium-doped fiber amplifiers.  About 120 mw was coupled from such a laser into single-mode fiber.

Abstract: A device for shaping portions of dough comprises a drum which rotates about a horizontal axis and which is provided at its periphery with alternating receiving apertures of two different sizes for the dough.  In each aperture, a plunger is guided in the radial direction of the drum; a restrictive guidance system is provided for the purpose of regulating the plunger.  A shift mechanism allows only one of the two apertures sizes to be aligned with the shaping device at anyone time; the device is therefore common to all aperture sizes.  This allows for a wider range of weight of the dough portions to be shaped.

Title: Process and apparatus for producing ultrafine explosive particles
Inventor: MCGOWAN MICHAEL JAMES
IPC: C06B21/00
Filed: 1991-08-27
Granted: 1998-11-17
Abstract: A method and an improved eductor apparatus for producing ultrafine particles is disclosed. The exclusive particles, which when incorporated into a binder system, have the ability to propagate in t hin sheets, and have very low impact sensitivity and very high propagation sensitivity. A stream of a solution of the explosive d issolved in a solvent is thoroughly mixed with a stream of an inert nonsolvent so as to obtain nonlaminar flow of the stre ams by applying pressure against the flow of the nonsolvent stream, to thereby diverge the stream as it contacts the explosive so lution, and violently agitating the combined stream to rapidly precipitate the explosive particles from the solution in the form of generally spheroidal, ultrafine particles. The two streams are injected coaxially through continuous, concentric orifices of a nozz le into a mixing chamber. Preferably, the nonsolvent stream is injected centrally of the explosive solution stream. The explosive sol ution stream is injected downstream of and surrounds the nonsolvent solution stream for a substantial distance prior to bei ng ejected into the mixing chamber.

Granted: 2000-04-25
Abstract: Soft handoff is provided in a mobile-to-mobile call in a cellular communication system, wherein a first mobile is moving from a first cell to a second cell, and the second mobile is in a third cell. The first mobile requests a handoff from the first cell to the second cell. In response, information regarding the call handoff is sent to the second and third cells. During handoff, the first and second cells receive radio transmission from the first mobile, and they both translate the transmissions into electronic data, packetize the data, and send the packetized data to the third cell. The third cell sends packetized data from the second mobile to both the first and second cells. Further, the second mobile may also move from the third cell to a fourth cell. The second mobile requests a handoff from the third cell to the fourth cell. Call data is sent to the fourth cell identifying the first and second cells. Call data is sent to the first and second cells identifying the fourth cell.  The first and second cells thereafter transmit packetized data to the third and fourth cells, and the third and fourth cells send packetized data to the first and second cells.

Granted: 2003-06-10
Abstract: A method for determining engine load of a spark ignition internal combustion engine. The method includes the steps of charging an ignition transformer to a maximum ignition charge and initiating an ignition discharge between electrodes of the spark plug. The ignition transformer is then charged to a predetermined diagnostic charge which is less than said maximum ignition charge. The diagnostic charge is discharged at a time of the combustion cycle where pressure in the combustion cylinder is dependent on engine load. The duration diagnostic discharge is then monitored and subsequently correlated to engine load. In this manner, the spark plug is used as a feedback element in determining engine load.
