Abstract: A method is given for diverting acids in matrix acidizing and acid fracturing.  The acids are diverted with a diverting agent that is an energized or foamed acidic viscoelastic surfactant system that contains a viscoelastic surfactant that gels and increases in viscosity when the acid in the foamed acidic viscoelastic surfactant system is spent. The method provides a synergistic combination of the diverting capabilities of foams and the diverting capabilities of viscoelastic gel systems. The resistance to flow of the gelled foamed viscoelastic surfactant system is greater than expected from a foam or a viscoelastic gel system alone.

Abstract: A lamp lighting system allows dimming of a compact gas discharge lamp to a low light output level without perceptible flicker. When the system receives a request to dim the lamp to the low level, the lamp is operated at an intermediate output level prior to operating the lamp at the requested low level. When the lamp cools to below a threshold temperature, the lamp is then operated at the requested low level. In one embodiment, the lamp is dimmed from its full rated output level to 1 % of its full rated output level. The intermediate level is approximately 2% to 5% of this full rated level. No flicker is perceived when the lamp level is reduced from the full rated level to the low level. Upon cooling, no flicker and no change in output level are perceived when the lamp is subsequently reduced from the intermediate level to the low level.

Abstract: Gel plugs that can be stored in a sealed condition and delivered individually to an electrophoresis gel as standards for electrophoretic separations are retained in a cartridge that is cleanly breakable into individual sections, each section retaining a gel plug of predefined dimensions with standard solute mixtures embedded in the plug. The separation of any single section from the cartridge exposes opposing edges of the gel plug which permits the user to insert an implement into the section interior and to urge the plug out of the section and into a well of an electrophoresis gel. All manipulations are performed without any need for contact between the user and the gel.

Abstract: The invention relates to a tunable resonant grating filter that can reflect optical radiation at a resonant wavelength, said resonant wavelength being selectively variable. The filter comprises a diffraction grating (3), a planar waveguide (4) and a light transmissive material having a selectively variable refractive index to permit tuning of the filter, said light transmissive material forming a tunable cladding layer (5) for the waveguide, preferably a liquid crystal (LC) material. The diffraction grating (3) is placed on the opposite side of the tunable layer (5) with respect to the planar waveguide (4) thereby making possible to tailor the grating structural parameters to the desired bandwidth of the filter response without significantly affecting the tunability of the filter. Within the resonant structure (1) of the present invention, the core layer, i.e., the waveguide (4), can be placed close to the tunable layer (5), either in direct contact with the tunable layer or with an interposed relatively thin intermediate layer(s) between the core and the tunable layer. Proximity of the core layer (4) to the tunable layer (5) implies that the propagation mode can significantly extend into the tunable layer (5) so that the effective refractive index of the fundamental mode in the waveguide (4) is efficiently affected by variations of the refractive index of the tunable layer (5).

Title: Secured phase-change devices
Inventor: COHEN MORREL H
IPC: G11C16/02
Filed: 2005-02-08
Abstract: An electronic device for securing the contents of data storage and processing elements. The device includes a security element and a phase-change element connected in a parallel arrangement. The security element is a three-terminal device, such as a conventional transistor or three-terminal phase-change device, having an ON state and an OFF state which differ with respect to resistance and regulate electronic access to the phase-change element by controlling the flow of electrical current applied to the parallel combination. In the ON state, the resistance of the security element is less than that of the phase-change element, thereby preventing, inhibiting or confusion a determination of the resistance of the phase-change element. In this PROTECT mode, the contents of the phase-change element are secured. In the OFF state, the resistance of the security element is greater than that of the phase-change material so that the resistance of the parallel combination approaches that of the phase-change element. In this READ mode, the resistance and information content of the phase-change element can be determined. The phase-change element includes a phase-change material and is preferably a chalcogenide based element. The phase-change element may perform a storage or processing function and includes registers and weighting devices as preferred embodiments.
