Abstract: Example field instrument temperature apparatus and methods for affecting or regulating a temperature of a field instrument are disclosed. An example apparatus includes a vortex tube having an inlet to receive a fluid, a first outlet to dispense a first portion of the fluid at a first temperature and a second outlet to dispense a second portion of the fluid at a second temperature, the second temperature being greater than the first temperature. The example apparatus also includes a first passageway fluidly coupled to the first outlet to direct the first portion of the fluid to an electronic device in a process control system to affect a temperature of the device.

Abstract: Laser apparatus and methods involving multiple amplified outputs are disclosed. A laser apparatus may include a master oscillator, a beam splitter coupled to the master oscillator, and two or more output heads optically coupled to the beam splitter. The beam splitter divides a signal from the master oscillator into two or more sub-signals. Each output head receives one of the two or more sub-signals. Each output head includes coupling optics optically coupled to the beam splitter. An optical power amplifier is optically coupled between the beam splitter and the coupling optics. Optical outputs from the two or more output heads do not spatially overlap at a target. The master oscillator signal may be pulsed so that optical outputs of the output heads are pulsed and substantially synchronous with each other.

Abstract: A precision positioning mount for UV-cured adhesives that provides adhesive junctions between modular assembly mounts and structural elements. Contact edges are placed on a first fixating area of an adhesive junction. The contact edges are pronounced edges of faces that slide along a second fixating area during the adjustment process. Thus, the assembly modules and structural elements are precisely referenced before, during and after their positioning and orientating. First and second fixating areas form a cavity that provides a volume for the adhesive. The mounts and structural elements are preferably made of sapphire for increased thermal conductivity. The elements of the assembly mounts are modular and interchangeable and provide various positioning modes.

Abstract: Optical, opto-mechanical and electro-optical elements (OE) of a Laser resonance assembly (LRA) are positioned and fixated in close proximity on an assembly plate by clamping the OE in a vacuum chuck that holds the OE on a clamping portion on the very top of it. The OE is brought into the predetermined position while a lateral attaching surface of the OE is kept in a predetermined angle relative to the assembly plate. A side mount is placed between the mirror and the assembly plate after an UV-curing adhesive has been applied. The attaching surface s and the adhesive have a specific relation between areal extension, surface roughness, uncured viscosity and uncured cohesive force.
