Title: Curling iron
Inventor: SAVONE UMBERTO
IPC: A45D1/10
Filed: 2003-08-07
Abstract: A curling iron is provided having two handles coupled to two heating tips having non-symmetrical cross-sectional shapes with respect to their lengthwi se axes. At least one of the heating tips is rotatably coupled to its handle to rotate along an axis lengthwise along the handle. Thus, by rotating the heating tips about axes along the handle length to orient the heating tip cross-sectional shapes with respect to each other so that various heating ti p contact surfaces are selected, the curling iron can be used to (1) curl hair to different curl shapes and tightness, and (2) straighten or flatten hair. Each curling iron handle may also include demountable heating tip and power cord couplings so that wires in the handle can be demountably connected to various heating tips, and can be demountably connected to an electrical powe r cord for powering the heating element coupled to that handle.

Title: System and method for expanding a pulse width
Inventor: BARTH SEVERIN
IPC: G11C29/02
Filed: 2003-11-04
Abstract: A circuit (10) and method for expanding the pulse width of a signal (20) based on the input signal's (18) pulse width. A circuit (10) generates a delay equal to the pulse width of the input signal ((18) for both a SHIFT (52) and OUT  (20) signal, which are out of phase with each other. The delay is generated when a capacitor (16) applies voltage to two control transistors in both the SHIFT (12) and OUT (14) blocks, reducing gate control in these transistors and generating a delay in the falling edge of these signals such that the pulse width of the SHIFT signal (52) is reduced and the pulse width of the OUT  signal (20) is increased. The capacitor (16) is charged by a transistor (22) activated by the SHIFT signal (52). The pulse-doubling system is self-converging: when the SHIFT signal's (52) pulse width is zero, the OUT signal's (20) pulse width is doubled, and the capacitor's (16) charging level is fixed since it is no longer charged by the transistor (22) controlled by the SHIFT  signal. The circuit (10) may be modified so that the output signal's (20) pulse width is a known factor of multiplication wider than the input signal's (18) pulse width.

Abstract: A method and system are disclosed for saving soft state information, which is non-critical for executing a process in a processor, upon a receipt of a process interrupt by the processor. The soft state is transmitted to a memory associated with the processor via a memory interface. Preferably, the soft state is transmitted within the processor to the memory interface via a scan-chain pathway within the processor, which allows functional data pathways to remain unobstructed by the storage of the soft state. Thereafter, the stored soft state can be restored from memory when the process is again executed.

Title: Protein stabilized pharmacologically active agents, methods for the preparation thereof and methods for the use thereof
Inventor: DESAI NEIL P
IPC: A61K47/42
Filed: 1997-09-24
Abstract: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water-insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful selection of the proper phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry powder comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.

Abstract: A system is provided for high volume print-forming of structures made up of multiple separate layers. A support bed is provided which has multiple steps arrayed thereon at different heights. Substrate blocks rest upon each of the steps. A printing process is utilized to print material from which the structures are to be formed down onto the substrate blocks. This printing process prints different layers onto each of the substrate blocks. The substrate blocks then move to a different step on the support bed and the printing process is repeated. Each support block has a partial structure thereon which receives its next successive layer in each printing cycle until the partial structure becomes a completed structure by having each of its layers sequentially printed thereon. Subsystems are provided for moving the substrate blocks upon the support bed and for properly holding and aligning substrate blocks upon the support bed.

IPC: G01V3/165
Filed: 2006-01-04
Abstract: A marine oil and gas exploration system used for measuring telluric currents as a natural electromagnetic energy source flowing beneath an ocean and sea floor. The marine exploration system includes a towed fish adapted for being pulled behind a survey ship.  The coordinates of the ship and the towed fish can be controlled by a GPS satellite and time data. The fish includes an aerodynamic waterproof housing, somewhat reminiscent of a shape of a fish.  Metal sheet electrodes of electric field sensors are mounted on the surface of a tubular nose extending outwardly from the housing. The electric field sensors are in direct contact with the sea water. Typically, the fish is towed approximately 100 feet above the sea floor. The positioning of the fish is maintained by the use of an acoustic "pinger" on the fish. The pinger transmits signals up a towed cable to the survey ship. The fish can also include a cesium magnetometer connected to the electric field sensors. The magnetometer provides for detecting low frequency magnetic components of the electromagnetic fields generated by the telluric currents flowing under the sea floor. A filtering of the magnetic component signals is used to provide a phase and amplitude references for the electric fields. The amplitudes of the electric field at each frequency are ratioed against the amplitudes of similarly filtered components of the magnetometer.

Abstract: A diffuser or orifice plate is positioned across the bore of a feed pipe supplying a mixture of pressurized air and recycled flue gas to the combustion chamber of a gas burner associated with a boiler. The diffuser plate comprises inner and outer, radially spaced apart, annular baffles. The baffles define a central opening and an outer series of openings forming an annular array. Part of the gas mixture is accelerated as it passes through the restrictive outer openings and forms an annular stream. Part of the gas mixture passes through the central opening in the form of a lance-like stream.    Fuel gas is injected into the annular stream immediately downstream of the diffuser plate. The resulting air/flue gas/fuel gas mixture mixes and adopts an elongated form in the combustion chamber.     The burner feed assembly described contributes to maintaining the NOx content in the burner flue gas at a low level such as less than 15 ppm.
