Microwave System Accelerates Concrete Curing

A Microwave Irradiated Pyrogen (MIP) system speeds up the concrete curing process. The use of a microwave allows the technology to operate in cold weather. Because the MIP accelerates the heating point, colder countries like Russia and Canada can use the curing system to build roads, tunnels, and other structures. The technology can also be used with precast concrete, mass concrete, and other construction needs.

Multiple-Component Fibers Strengthen Non-Woven Fabric

A technology provides a full-surface, bonded, nonwoven fabric with a tensile strength suitable for packaging, bubble packs, and other applications requiring tear resistance. Fullwidth bonding, compared to the more common patterned point bonding, produces the high-strength fabric. The thin, low-cost material can be easily manufactured in smooth calendaring plants. Low voids reinforce the fabric.

Microwave Energy Removes Fuel- Processing Impurities

A traditional sulfur-adsorption bed uses microwave energy to remove, or desorb, captured impurities. Conventional adsorption beds use heat and sometimes vacuum to cleanse the bed of sorbents; the process is energy-intensive and can reduce sorbent life. By using microwaves, the new technology desorbs the captured impurities from the bed with little or no change in temperature.

Acceleration Sensor Enables New Robotics Applications

The Inclinos 3DS inclination and acceleration sensor, based on thermodynamic effects, exhibits no hysteresis in response signal (output lag). A power distribution of four heaters is controlled by a closed loop, and the temperature of each heater is constantly affected by any acceleration. The sensor has no moving parts, no inertial mass, and offers high responsivity from the idle position. Depending on the angle, the Inclinos measures 360-degree inclination on two axes.

Water-Based Cooling Fluid Reduces Corrosion

A water/propylene glycol-based formulation acts as a heattransfer medium and reduces the corrosion of sensitive metals by 10x to 100x in heat exchangers, radiators, cold plates, and associated plumbing. The water-based cooling fluid can be used with equipment containing a variety of metals, while still providing freeze protection.

Manufacturing Process Supports Cost- Effective TPM Production

Transverse Flux Machines (TFMs) are brushless motors and generators that use permanent magnets. A TFM’s direction of magnetic flux is perpendicular to the direction of force, instead of parallel to it, as in a standard electric motor or generator. The machines are also inherently lighter, smaller, more power dense, and more powerful.

Land-Intensive Solar Tracker Generates Photovoltaic Power

A solar tracker enables the construction of independent power sources and a micro-grid. The mechanism of the land-intensive system has two independent virtual axes for azimuthal moving and altitude moving. After the solar panel is aligned, the tracker drives it to move from east to west until the amount of change of the Sun’s altitude reaches a specific level.
