Pulsed Electric Field Food Processing
Pulsed Electric Field Food Processing Customer Case Pulsed Electric Field Food Processing is a continuous food processing system in which beverages (with a known conductivity) are pumped through a chamber containing an electrode. Pulses of high voltage electricity are passed across the electrode, thus through the liquid as well. It is a pasteurization technique being studied at Ohio State University. The need is to be able to monitor, display, and record to hard drive storage, voltage and current waveforms. They need to be able to draw information about the pulse duration, peak voltage, etc. from the recorded waveforms. Waveforms [...]
Blade Tip Clearance
Blade Tip Clearance Power Generation Blade Tip Clearance Tolerances Introduction Blade Tip Clearance Solutions for Turbines, Fans, and Rotating Machinery When it comes to turbines and fans, blade tip clearance — the distance between the tip of the blade and the surrounding case — is one of the most crucial measurements. If the blade tips are too close, thermal expansion or vibration could cause destructive contact. If they’re too far, turbine efficiency and performance suffer. That’s why accurately measuring turbine blade tip clearance, fan blade tip clearance, or any [...]
Phase Conjugate Sonar
Phase Conjugate Sonar Customer Case Dissipationless physical systems, such as simple planetary motion or a swinging pendulum, exhibit time-reversal invariance. This means that if time were reversed the way a film projector can be, then the resulting motion would be allowed by the equations governing the system. It follows that if all velocities in a dissipationless system are suddenly reversed, the system will follow a time-reversed trajectory. Dissipationless or adiabatic wave propagation is time-reversal invariant. Phase Conjugate Optics involves the deliberate reversal of complex light paths. A customer is doing Phase Conjugate Sonar using sound instead of light. The [...]
Exploration Of The Elastic Region For Aluminum Alloys
Exploration Of The Elastic Region For Aluminum Alloys Research & Development Exploration Of The Elastic Region For Aluminum Alloys Bending, Tensile and Compression Description One of the most crucial properties of metals, including aluminum alloys, is their elastic characteristics, which define the extent to which a material can deform and return to its original shape once the applied load is removed. This behavior is particularly important when working with materials in engineering and industrial applications, where understanding the elastic region of the stress-strain curve is vital. The stress-strain curve for [...]

Tolerances of Armature Gaps
Tolerances of Armature Gaps Power Generation Tolerances Of Armature Gaps Tolerances Description Introduction In large motors and generators, the air gap needed to separate the revolving rotor from the stator should be as small as possible as this reduces the magnetizing power requirement. The gap also needs to be large enough to prevent contact between the two, despite manufacturing tolerances on their dimensions or movement resulting from mechanical deflection or looseness in supporting bearings. The gap should also be uniform; a non-uniform gap causes increased noise and vibration. Since large [...]

Ultrasonic Horn Vibration
Ultrasonic Horn Vibration Research & Development Ultrasonic Horn Vibration Amplitude Description An "ultrasonic horn" is the device which concentrates this energy and applies it to a process. They come in many different sizes and configurations depending on the task for which they are designed. As the tip of the horn (or contraction area) is brought in contact with a part at a certain pressure, frictional heat is generated causing the material to plasticize locally, creating an insoluble connection between two parts within a very short period of time. As the [...]
Wafer Measurement – Ungrounded
Wafer Measurement - Ungrounded Semiconductor Wafer Measurement - Ungrounded Metrology Description MTI Instruments Inc. has developed a thickness measurement device that eliminates the effect of varying target conductivity. Called the Push-Pull probe, it’s a unique version of the AccumeasureTM amplifier series. This special design provides accurate surface information for wafer bow and warp. Bow is the deviation of the center point of the median surface of a free, un-clamped wafer from the median surface to the reference plane. Where, the reference plane is defined by three corners of equilateral triangle. This [...]
