20060007666, Jan 12, 2006

Filed:

Jul 8, 2004

Appl. No.:

10/887463

Inventors:

Kenneth Cook - Salinas CA, US

International Classification:

G03B 15/02

US Classification:

362016000, 362351000, 362355000

Abstract:

A light modifier for creating an enhanced depth of lighting on a subject. The light modifier has a housing with a sidewall that defines a first and second end. The first and second ends are in opposed relationship. The first end is adapted to mount a light source in the housing. A panel is positioned on the second end of the housing. The panel has at least one layer of netting having an aperture. Light that passes through the netting has different characteristics than the light passing through the aperture whereby the light modifier creates enhanced depth of lighting on a subject.

Abstract:

A color printing apparatus and method in which a light chamber receives light from a light source after the light has passed through a negative supported by a negative carrier. The light chamber has a number of electronic sensors which sense the light in the chamber and control filters across the path of the light before the light strikes a color paper strip for printing the image of a negative onto the strip itself. In one embodiment of the invention, a negative carrier has a number of slots adjacent to the opening in the carrier across which the negative is to be placed in the path of the light beam. These slots provide passages for additional light from the light source into the light chamber whereby the light passing through the negative and the additional light is mixed together to dilute the total light in the chamber to normalize the readings of the sensors before the sensors are used to actuate filters across the path of the light beam. In another embodiment, light from a light source can be directed into the light chamber along a path defined by a light passage, such as a fiber optics bundle. In a third embodiment, the invention can include a light source in the light chamber itself with the light source being actuated when light passes through the negative for exposing the image on a color paper strip.

Appl. No.:

5/637582

Inventors:

Kenneth C. Cook - Walnut Creek CA

Assignee:

Systron-Donner Corporation - Berkeley CA

International Classification:

F16K 1740

US Classification:

137 68A

Abstract:

Valve apparatus is disclosed for discharging pressurized fire extinguisher fluid from a container. The valve includes a diaphragm which is removably mounted within a two-part housing to facilitate field replacement. The diaphragm is formed with a semi-spherical shell which is mounted across a passage in the housing with a concave side of the shell facing the pressurized fluid. The shell is fabricated of a metal which is pre-stressed so that the diaphragm ruptures above a predetermined fluid pressure for relieving over-pressure from the container. An annular rim of the diaphragm includes a ductile metal ring which is compressed between the housing parts into fluid sealing relationship with an annular knife edge seal. A squib cartridge is mounted in the housing to rupture the diaphragm and permit the fluid to discharge through the passage. A screen is mounted in the passage to screen out fragments of the ruptured diaphragm from the flow stream.

Abstract:

Valve apparatus is disclosed for discharging pressurized fire extinguisher fluid from a container. A valve housing includes a valve body and manifold between which a diaphragm which is removably mounted to facilitate field replacement. The diaphragm comprises a semi-spherical shell which is mounted across a passage in the housing with a concave side of the shell facing the pressurized fluid. The shell is fabricated of a metal which is pre-stressed so that the diaphragm ruptures above a predetermined fluid pressure for relieving over-pressure from the container. A dual seal is formed about the rim of the diaphragm by means of an O-ring and an annular knife edge which are disposed within a recess of the manifold body. The valve body and manifold are secured together in metal-to-metal contact at their interface to prevent leaking. A squib cartridge is mounted in the housing to rupture the diaphragm and permit the fluid to discharge through the passage.
