Par-Baked Goods Gain Ground with Cryogenic Freezing

Fresh-from-the-oven signature breads at retail were once almost the exclusive province of fine restaurants, but the rise of commercial par-baking has made it possible for any restaurateur or food retailer to produce even artisan breads without skilled labor. "Cryogenic freezing of par-baked goods is giving commercial bakers who have only...

UTA Hosts DUNE16 Collaboration Meeting

Over 150 leading international physicists convened in early January at The University of Texas at Arlington to collaborate on the game-changing particle physics experiment known as the Deep Underground Neutrino Experiment, or DUNE.

IUPAC adds four superheavy elements to periodic table

The International Union for Pure and Applied Chemistry (IUPAC) welcomed the new year with a bang, confirming the discovery of four new elements and once again shaking up the periodic table. Elements 113, 115, 117 and 118 complete the seventh row of the table. Each has been assigned a temporary...

Lockheed cuts F-35 part cost with cryogenic machining system

Lockheed Martin engineers have demonstrated a 52 percent increase in cutting speeds associated with roughing and finishing operations on large titanium airframe components for the F-35 program. The tests made use of an Okuma MA-600HII horizontal machining center equipped with 5ME’s patented cryogenic machining system.

NIST researchers enhance photon detection accuracy

National Institute of Standards and Technology (NIST) researchers announced on January 5 advances in the fabrication of superconducting nanowires that improve the precision of detecting individual particles of light by 74 picoseconds.

Helium II

Helium II (He II) refers to the second liquid phase of the most abundant helium isotope (4He). Helium II is also referred to as superfluid helium. Helium II occurs once the temperature of the liquid helium drops below 2.17K. The phase transition between the first liquid phase of Helium (referred...

Food Processing

Cryogenics and Food The industrial gas industry provides a host of products and services related to food. The various gases have useful and sometimes fascinating applications in food industry. “The food industry is not a homogenous industry. The needs of customers processing hamburger vs. poultry vs. strawberries vs. seafood, for...

Primary Standards

Shrink Fitting

Robin A. Rhodes Cryogenic Institute of New England, Inc. rrhodes@nitrofreeze.com Shrink fitting, (or “compression fitting” as it is sometimes called), is a method used to insert a pin or bushing into a housing or other assembly requiring an extremely tight tolerance fit. It can be used as an alternative to...

Telecommunications

From the Winter 2004 issue of Cold Facts magazine The recent M-Calc IV — 4th Industry Assessment workshop discussing military and commercial applications for low-cost cryocoolers, held in November in San Diego, highlighted progress being made in cryogenics as applied in telecommunications. The reliability and long lifetime of projects now...

An Issue of Pressure and Flow Rate in a Supply Tank

Please help solve this problem: A supply tank requires a vaporizer to generate sufficient pressure to pump stored fluid up into a vehicle or tank. The available head is limited as the tank level falls and it is important to minimize the system pressure drop to maintain the desired flow...

Using MLI on VJ Line Joints or Cryo Storage Tanks

When installing Multi Layer Insulation (MLI) blankets on VJ line joints or cryo storage tanks should they be wrapped and tied down tight or loose? These are usually pre-cut to size. Also should they have an access hole at the point of where the molecular sieve is installed to help...
