Abstract:
This invention relates to the field of balloon catheters and more particularly to catheter balloons having controlled failure mechanisms for the prevention of catastrophic failure of the balloon during overpressure conditions.
Abstract:
A process of removing trace levels of metallic impurities from resist or photoresist component solutions and obtaining a purer resist or resist component solution without isolating the resist or resist component as a solid by treating the resist or resist component solution with an aqueous solution of a water soluble oxidizer, such as hydrogen peroxide, then with an acidic aqueous solution, and then allowing organic and aqueous phases to form with said aqueous phase containing metallic impurities extracted from said organic phase and the organic phase containing said resist or resist component solution with reduced amount of trace metal impurities, and separating the two phases.

Abstract:
A new anti tip safety attachment for ambulatory aids that provides the stability needed to help keep ambulatory aids from being inadvertently pushed or tipped over. The Support Arm is universal and comes in a pair with each set being comprised of a 2 piece leg clamp molded from non toxic polymer plastic, 4 steel screws and a support arm made of approximately 1″ anodized aluminum tubing with a rubber stopper on the end. The 2 piece leg clamps attach to the ambulatory aid with the support arm facing out and down with the rubber stopper at least 1″ from the walking surface. There is no need to engage The Support Arm once secured and it will fold with the ambulatory aid.
Abstract:
A method and apparatus for reducing the emissions and improving the performance of an internal combustion engine (40). An input air stream is separated into an oxygen-enriched air stream and a nitrogen-enriched air stream. The nitrogen-enriched air stream is received by a holding chamber (35). The oxygen-enriched air and a combustible fuel are provided to a combustion chamber (45) of the internal combustion engine (40) and a combustion process is initiated. After a predefined time delay, a volume of nitrogen-enriched air is provided from the holding chamber (35) to the combustion chamber (45) to be used during the rest of the combustion process.
Abstract:
The present invention provides an applicator for applying and distributing a substance onto a target surface. The applicator comprises a substantially planar sheet of compressible, conformable material having opposed first and second surfaces and an interior region between said first and second surfaces. The applicator further includes at least one discrete reservoir underneath the first surface which is at least partially filled with a substance and at least one discrete aperture formed in the first surface which is in fluid communication with the reservoir. Compression of the applicator via an externally-applied force substantially normal to said first surface expresses product from the aperture and translational motion of the first surface relative to a target surface applies, and distributes said product onto the target surface. In one embodiment, an applicator provides a removable cover sheet which aids in the containment of the substance. In another embodiment an applicator has a smaller size and/or caliper which resembles the handling and storage practices of a credit card. A wide variety of substances are contemplated, including particularly antiperspirant/deodorant products.
Abstract:
An RF screened housing (1;13) according to the invention contains a screening plate (2;15) and having at least two mutually opposite side walls (3;16), which project from said screening plate (2;15) and are designed to engage behind rims of a printed circuit board (5;14), which is fitted with the RF screened housing (1;13), as well as elastic means (7;18) which can be pressed against at least one of the main surfaces of the printed circuit board (5;14) in order to clamp them at the rims to the side walls (3;16).

Abstract:
A method for obtaining a product from pre-alloyed powders in which the powders are subjected to compaction treatment. The powders are first subjected to pre-treatment under low pressure (or without pressure) at a temperature such that segregating materials precipitate out in stable phases.
