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.

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.

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.

Electronic Device Prevents Hearing Loss

MP3 and MP4 players, along with powerful Class-D headphone amplifiers, can cause hearing loss due to a continuously high sound pressure level (SPL). A Hungarian university has developed an electronic device for preventing hearing loss and simulating ear distortion. The invention is a simple module that models the distortion of the human ear and produces natural sound experience with low sound pressure level.
