Abstract: A visualization device is described. The visualization device includes a body, one or more activating lights sources and one or more infrared light sources. The body is configured to receive one or more power sources. One or more infrared light sources are configured to determine temperature. The one or more activating light sources may be positioned at or proximate an end of the bode that is substantially opposite to the infrared light source and are configured to produce activating light. The activating light sources and the infrared light sources are separately or jointly coupled to one or more power sources. Methods of detecting leaks using the visualization device are also described.

Abstract: A visualization device is described. The visualization device includes a body. The body includes a cavity configured to receive one or more components. One or more activating light sources may be positioned in the cavity of the body and are configured to produce activating light. One or more white light sources may be positioned opposite to the activating light source in the cavity of the body and are configured to produce white light. The activating light sources and the white light sources are both coupled to one or more power sources. Methods of detecting leaks using the visualization device are also described.

Abstract: A pressure gauge apparatus for determining refrigerant pressures in a refrigeration system and methods of use are described herein. The pressure gauge apparatus may include a pressure gauge and a faceplate. The faceplate may be rotated such that ambient temperature and a pressure range are visually indicated on the pressure gauge. The pressure range may correlate to an adequate amount of refrigerant in the refrigeration system at ambient temperature.

Abstract: A combination pressure measurement/charging system may include a conduit coupled to a refrigerant can. The conduit may be coupled to a low-pressure side of a refrigerant system. The system may include a valve to control a flow of fluid through the conduit. Thus, a flow of fluid between the refrigerant can and the low-pressure side of the refrigerant system may be controlled using the valve. A first pressure gauge may be in fluid communication with the conduit. The first pressure gauge may be coupled to the low-pressure side of the refrigerant system. The first pressure gauge may be used to operate the valve to control fluid flow through the conduit. A second pressure gauge may be coupled to a high-pressure side of the refrigerant system. The second pressure gauge may be isolated from fluids that flow through the conduit.

Abstract: A combination pressure measurement/refrigerant charging apparatus may include a shutoff valve that includes a piercing pin and a pressure gauge. The piercing pin may be used to pierce a refrigerant can. The pressure gauge may be used as a handle for operating the shutoff valve. A first end of a hose may be coupled to the shutoff. A quick coupling device may be coupled to a second end of the hose. The quick coupling device may be used to couple the apparatus to a refrigerant system.

Abstract: A multi-channel fiber optic cable connector is provided for connecting the terminal ends of fiber optic cables utilizing continuous ceramic sleeves to align the adjacent termini of optical fibers included within respective ones of the cables. The continuous ceramic sleeves have internal bores which are slightly larger than the outside diameter of the periphery of the termini, providing a clearance fit between the continuous ceramic sleeves and respective ones of the termini. The termini are independently gimbaled, with gimbal points being disposed distally from respective mating planes between opposing terminal ends of the termini. Floating seal assemblies extend around respective ones of the termini between the mating planes and the gimbal points, and seal between the respective ones of the termini and a connector housing. The floating seal assemblies each include an annular-shaped, floating collar having an aperture through which a respective one of the termini extends.

Abstract: A resilient sign and guidepost is presented which is suitable for use along roadways for marking the roadway or supporting various roadway signs, the resilient post is comprised of an elongated flexible tube body combined at a lower end portion with a driving stake means inclusive of a suitable driving head for insertion into the ground. The driving stake means supports the elongated flexible tubular body as well as an axially aligned reinforcing rod or rods positioned in the hollow tube body and extending from the driving head of the stake means through a substantial portion of the length of the tubular body. In another embodiment, a solid elongated one-piece resilient post terminating at a lower end portion in a driving stake and driving head means is presented wherein both embodiments provide for driving force to be exerted against the driving head means or the stake portion thus allowing a resilient post member.
