International Classification:

A01N 2532

US Classification:

424406, 424405, 510101, 514642, 514643, 514739, 514762

Abstract:

The present invention provides an improved antimicrobial composition which includes at least one quaternary ammonium compound and nerolidol. The nerolidol component of the composition provides enhanced antimicrobial efficacy, even when used in small amounts. Further, the nerolidol component provides such enhanced antimicrobial efficacy that the quaternary ammonium compound may be used in reduced amounts as compared to the amounts used for antimicrobial effect in prior formulations. The enhanced antimicrobial composition of the present invention is especially useful in cleaning or disinfecting applications, such as the cleaning of hard surfaces.

International Classification:

G02B 6/34

US Classification:

385 37, 385 50

Abstract:

A colorless tunable optical dispersion compensator (TODC) comprising a silica arrayed-waveguide grating (AWG) directly coupled to a polymer thermo-optic lens. As a result of its inventive construction, the device exhibits low loss, large tuning range, low electrical consumption and is readily manufactured using standard processes. Additionally, the TODC is fully solid-state and scales to a large figure-of-merit (dispersion range times bandwidth squared).

Appl. No.:

11/713988

Inventors:

Robert Blum - Palo Alto CA, US

International Classification:

G02B 6/34

US Classification:

385037000

Abstract:

A tunable optical waveguide chip for optical transforms. Roughly described, the chip includes a planar waveguide having a lens region and a plurality of individually addressable energy applicators distributed transversely across an optical path through the lens region. By individually controlling the energy applied to each of the energy applicators, a desired index of refraction profile can be induced in the lens region transversely across the optical path for performing any of a variety of optical transforms. The device may include an upstream AWG which focus a wavelength de-multiplexed signal on a focal plane within the lens region. The applicators may be thermo-optic or electro-optic, for example.

International Classification:

C11D 302
C11D 339
B08B 300

US Classification:

510191

Abstract:

A thickened, buffered aqueous acidic cleaning composition suitable for removing mineral deposits is provided. In one embodiment, the composition comprises a weak acid and its conjugate base wherein the weak acid has a pK. sub. a of approximately 2 to 3. 5 and where the composition has a pH of approximately 2 to 3. 5. Organic acids, such as citric acid, are particularly suited. The addition of a thickening system comprising cetyl trimethyl ammonium chloride and sodium xylene sulfonate or alkyl diphenylether sulfonate produces a viscoelastic composition in which the viscosity can be controlled by the level and/or ratio of the surfactant/counterion. Suitable stable adjuncts including fragrances, dyes, organic solvents, disinfectants, and bleaches can be added to the composition.
