    摘要： A lamp system is for use in non-destructive testing to illuminate luminescent materials, such as fluorescent dyes. The lamp system has a control unit and a lamp. The lamp has a bulb and a filter. The bulb generates at least a first wavelength of invisible energy and the filter limits other visible wavelength light from the lamp. The lamp has a handle with a trigger. The control unit pulses the lamp on and off when the trigger is depressed. The lumiescent material absorbs the first wavelength of energy and pulses in response when the lamp illuminates the material. The system can be AC or DC operated. It can be operated from an automotive battery. A fault locating system for use with fluorescent dyes to detect faults in a body has a handheld D-type battery flashlight configuration with a casing having a handle at one end and a flared lamp housing at the other. A reflector fits within the lamp housing, and a bulb rests in the reflector. The bulb is an ultraviolet light source, for example tungsten halogen or a Xenon flashtube. A lens fits over an open end of the lamp housing to allow transmission of substantially more ultraviolet than visible light. The lens may be a dichroic filter. The bulb may be flashed to cause the fluorescent dye to re-emit pulses of light visible to the naked eye.

    摘要： The use of sealants based on organosilanes for refrigeration and air conditioning systems is made possible by control of the rate of introduction and viscosity of the sealant mixture within certain ranges. An appropriate choice of organosilane sealant is made to allow effective sealing of small pinhole size leaks in the air conditioning or refrigeration system. The organosilane is then combined with a miscible lubricant at particular ratios to provide the proper mixture viscosity for injection into the refrigerant system to prevent bearing seizure. Specific orifice sizes are selected for an apparatus to ensure that the composition is injected at the flow rates required to prevent liquid slugging and subsequent compressor shutdown or failure. In addition, effective introduction of the mixture requires certain procedures be performed. Injection procedures are also described that prevent temporary or catastrophic equipment shutdown.

    摘要： An air powered flush machine capable of circulating a highly volatile flushing solvent through an air conditioning system or system components and then also capable of circulating a high volume of air through the system or components, to blow the solvent out of the components and thoroughly dry the system or components, without emitting an objectionable level of odour or hazardous level of fumes through the machines air exhaust outlet. The machine utilizes a receiving tank design which separates liquid solvent from the air flow before exhausting the air through its exhaust filter.

    摘要： LED lamp has LEDs aimed rearwards with either a concave mirror to the rear of each LED, or one concave mirror to the rear of two or more LEDs, collecting the light from the LEDs to form a forward projecting beam. LEDs may be high power types that require heatsinking. LED lamp may have a lens forward of each LED to collimate the radiation produced by the LEDs into a beam, where at least one lens has at least one aspheric curved surface. LED lamp may have a transparent reflective optic to collimate the radiation produced by each LED into a beam. For an inspection lamp, the LEDs typically have a peak wavelength of 395 to 415 naometers for seeing the area being irradiated but not so visible as to overwhelm fluorescence of fluorescent materials to be detected. Other wavelengths may be used. LED inspection lamp has a combination of LEDs of different wavelengths or a combination of at least one LED and at least one other light source such that the lamp produces radiation suitable for detection of materials to be detected and adequately illuminates the area being irradiated. LED lamp has LEDs that produce a beam of suitable radiation with a width of 10 degrees or less without additional optics. LED inspection lamp has head attached to a flexible member, with head serving as heatsink for one or more high power LEDs. Current regulator circuits are also disclosed.

    摘要： There is provided an apparatus having at least one LED capable of emitting near ultraviolet or ultraviolet radiation to excite a luminescent material for non-destructive fault testing. The radiation may also be focused using a lens. There is also provided a method for detecting a fault in a body, comprising the steps of applying a luminescent material to the body in a manner to concentrate the luminescent material in a pattern indicative of the location of a fault in the body; activating an LED to emit ultraviolet radiation; shining the radiation transmitted from the LED onto the body to excite the luminescent material; and detecting a fault by the fluorescence of the luminescent material indicative of the location of the fault in the body.

    摘要： A conduit is provided for use in association with an air conditioning or refrigeration system. The conduit has first and second conduit portions, and a swivel providing fluid communication between the first and second conduit portions. The swivel permits rotational movement of the first conduit portion relative to the second conduit portion. The swivel is constrained to prevent linear movement between the first and second portions at the swivel. The conduit also has a fitting for external connection of the conduit to a pressure port of an air conditioning or refrigeration system. The conduit provides sealed fluid communication from the first conduit portion, swivel and second conduit portion to the air conditioning or refrigeration system when the fitting is connected to the air conditioning or refrigeration system. There are also conduit adapters, injection hose assemblies, charging manifolds with swivels, and methods of utilizing such conduits and swivels.
