A method of making a hermetically-sealed feed-through device includes inserting an elongate conductor or conductors within a hollow portion or portions of a plastic insulator body and inserting the plastic insulator body within a hollow outer jacket to form an assembly. At least one of the conductor or conductors, insulator body, or jacket of the assembly has a plurality of circumferential grooves. Thereafter, the assembly is crimped and/or is swage-crimped at ambient temperature to cause the materials of the conductor or conductors, insulator body, and outer jacket to be displaced or extrude into the grooves thereby creating mechanical interlocks between the conductor or conductors, insulator body, and outer jacket. Additional methods and feed-through devices made by the methods are also disclosed.

Hermetically-sealed feed-through device and method of assembly

Apparatus for analyzing fluid or surfaces within a pipeline or vessel includes a probe positioned to capture or record images through a viewing port of the pipeline/vessel and an illumination assembly arranged to illuminate the fluid/surfaces within the pipeline/vessel adjacent the port with visible, infrared or ultraviolet light of a predetermined wavelength or within a predetermined range of wavelengths. Depending upon the type of fluid, light or radiation of a particular wavelength may be required to capture an image of high contrast and clarity. Accordingly, an electronic controller communicates with the probe and the illumination assembly for automatically controlling operation thereof so that images are captured and recorded of the fluid illuminated with light of different predetermined wavelength or predetermined range of wavelengths. An analyzing unit analyzes the images and identifies an image of greatest level of contrast or clarity and the wavelength or predetermined range of wavelengths of the light used to illuminate the fluid for the image of greatest level of contrast or clarity. A method is also disclosed.

Apparatus and method for analyzing fluids in vessels and pipelines

A method of analyzing bubbles, cells, cell viability, or other particles or agglomerates in a process liquid contained in a vessel is provided. Images of bubbles, cells or other particles in the liquid are obtained in-situ with a vision probe extending through a wall of the vessel. The images are analyzed with image recognition software. The software measures at lease one of bubble, cell or particle size, mean diameter, surface area, flow rate, flow pattern, population distribution, viability, agglomerates or clumping, color change, viscosity, Sauter mean, ratio of surface area of bubbles relative to volume of bubbles, gas hold-up ratio of gas volume to volume of liquid, or interfacial area. The software distinguishes valid or viable bubbles, cells or particles that should be included in an analysis from invalid or non-viable bubbles, cells or particles that should not be included. The software can be configured to provide an analysis of the valid bubbles, cells or particles that fall within pre-set size and shape or viability parameters.

Image recognition and analysis system and software

A remote vision analysis system for a vessel containing a process liquid having gas bubbles or particles floating therein. A probe extends into the vessel and enables in-situ observation of the process liquid, gas bubbles or particles, and/or surfaces within the vessel. The probe has a proximal end that includes a camera for recording still or motion images of the process liquid, gas bubbles or particles, and/or surfaces within the vessel. An elongate distal end of the probe extends within an interior of the vessel and is housed within a hermetically sealed protective shroud having a lens, or window, through which images are recorded by the camera. The probe is modular and includes interchangeable parts.
