10/178939

Inventors:

Milton Ives - North Windham CT, US

Assignee:

CiDRA Corporation - Wallingford CT

International Classification:

B05D001/18

G02B006/22

US Classification:

427/431000, 427/163200, 385/128000

Abstract:

A method of applying a metal coating to optical element, such as an optical waveguide, comprising the steps of partially depleting stabilizers in an electroless metallic solution and immersing an optical waveguide in the electroless metallic solution to deposit the metal coating to the optical waveguide. The step of partially depleting may include creating an electroless metallic solution having a sodium hypophoshite concentration of about 25 grams per liter. The electroless metallic solution may comprise a Fidelity solution 4865A, a Fidelity solution 4865B and de-ionized water in a ratio of 1:1:18; and sodium hypophosphite crystals. Alternatively, the step of partially depleting may include placing a dummy load into the electroless metallic solution. The dummy load may be a rectangular block of metal, formed of a low carbon steel, and may have a threaded cylindrical passage therein. After depleting the stabilizers, the optical waveguide is immersed in the electroless metallic solution for a predetermined length of time depending on a desired deposition thickness.

Abstract:

Optical connector assemblies suitable for use in harsh environments such as down hole oil and gas well applications and methods for fabricating the same are provided. In one embodiment, an optical connector assembly suitable for down hole oil field applications comprises a first and second optical waveguide urged by a biasing member against a bracket. Each of the waveguides has at least one base surface formed on the exterior of the waveguide that is disposed against at least one of a plurality of reference surfaces of the bracket. In another embodiment, flats comprise two of the base surfaces on each optical waveguide. In another embodiment, a method of fabricating an optical connector assembly suitable for down hole oil field applications includes the steps of forming a first flat on a first optical waveguide, forming a second flat on the first optical waveguide, forming a first flat on a second optical waveguide, forming a second flat on the second optical waveguide, and biasing the first flats of the first and second optical waveguides against a first seating surface and second flats of the first and second optical waveguides against a second seating surface.

International Classification:

H01H 2100

US Classification:

200 6BA

Abstract:

A three position switch has three blade or strip type fixed contacts, which can be assembled by insertion in slots provided in the switch case. The switch has a stable center-off condition without requiring a yoke on the center fixed contact. The movable contact cooperates with the actuator's plunger portion to define this center-off switch condition and the elimination of such a yoke provides a simpler switch.
