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.

Dissolution Device

To enhance transportability and shelf life, many drugs and pharmaceuticals are distributed as freeze-dried formulations. The formulations must be dissolved before they can be injected. A client therefore seeks a new device or container that helps lyophilized preparations dissolve rapidly and completely with diluents such as water. It is possible to improve dissolution by longer or faster stirring, or by heating, but the proposed solution must not apply heat or create bubbles. The formulation, intended for injection, needs to work with a variety of powdered drug types, thus showing versatility.

Grab-Bars and Safety Grips

Because of their weight and the weight they bear, most grab-bars must be installed permanently in a home, usually by drilling through the wall material and into a wall stud. In the case of grab-bars installed in a tub enclosure or shower, a permanent hole may need to be drilled through ceramic tile, thus making a change to the material that is difficult to patch if the bar is removed later. A company desires a grab-bar solution that can attach to any surface, including tile or drywall, and later be removed without marring the underlying surface. The grab-bar must support up to 250 pounds and include a consumable or renewable feature.

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.

Adhesion Prevention for Sheet Goods

A company produces and stacks sheet goods that have a naturally viscous and sticky surface material. The sticky material is applied at about 480 °F. During application, the coating has a specific gravity of 1.03 to 1.70, and a viscosity of >5000 cps. A release material needs to be applied to the substrate material during production so that the sheets do not adhere during shipment and storage. Even at 480 °F, the coating cannot decompose, melt, mix, delaminate, or combine with the underlying substrate. The organization is open to any application method, such as roll-to-roll, spray, paint-on, or application via tape.

Smooth Dispensing of Adhesive

Without producing clumps, a professional adhesive must be poured in a consistent and smooth way. A company seeks a dispenser/ applicator that can handle a thick, gelatinous, preformed, professional-quality adhesive. Currently, a polymer dispersion of polyvinyl pyrrolidone is used. While the stearates thicken the adhesive and provide an even “flow,” they bring the compression/shear strength of the formulation down to 400-600 lbs. A proposed professional-level adhesive must dispense just as well, but offer a compression shear strength of 2000-2500 lbs. The substrates to be joined include such porous substrates as wood and engineered wood products, and various non-porous surfaces such as metal and plastic.

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.
