Abstract: A compact push-pull exercise apparatus having a partial turn outer cam surface in contact with a random surface such as a floor, and one or more handles rotatably mounted to the cam rotational axis. The operator begins an exercise cycle in the kneeling position with hands on the handles and with arms generally near the vertical position. The operator pushes the apparatus forward to a stopping position with the operator nearly prone. During the first portion of the forward movement, gravitational energy is stored as the cam rotational axis is lifted. As the operator reverses the movement from the prone position to the kneeling position, gravitational energy is released during the first portion of the in-stroke to ease the return motion during the most difficult portion of the exercise cycle.

Abstract: A process for angularly sueding a textile web containing fill and warp yarns with the steps of: supplying the web, controlling the tension of the web, engaging the web with at least one diamond-coated abrasive treatment roll disposed at an abrasion angle, rotating the treatment roll at a surface speed different from that of the web, and taking up the supplied web. A preferred embodiment comprises a pair of spaced treatment rolls disposed at an abrasion angle, and rotating in opposite directions relative to the web. The related apparatus for this specific process is also provided.

Abstract: The inventive method provides highly desirable hand to various different types of fabrics through the initial immobilization of individual fibers within target fabrics and subsequent treatment through abrasion, sanding, or napping of at least a portion of the target fabric. Such a procedure includes “nicking” the immobilized fibers thereby permitting the fibers to produce a substantially balanced strength of the target fabric in the fill and warp directions while also providing the same degree of hand improvements as obtained with previous methods. Furthermore, this process also provides the unexpected improvement of non-pilling to synthetic fibers as the “nicking” of the immobilized fibers results in the lack of unraveling of fibers and thus the near impossibility of such fibers balling together to form unwanted pills on the fabric surface. Fabrics treated by this process are also contemplated within this invention.

Abstract: The disclosure relates to the stabilization of a fluid drop comprising a liquid solvent and solute, so that upon drying of the solvent, the solute is not preferentially concentrated at the edges of the residual spot, and more particularly relates to the preparation of microarrays containing biological reagents.

Abstract: A zipper including two stringers, each stringer having a row of coupling elements having a plurality of coupling element spacings, and at least one stringer having a plurality of coupling element widths.

Abstract: The present invention provides a unitary syringe having a mounted needle surrounded by a sheath having a break-zone. The fluid medicament to be injected is contained within a blister cavity formed between upper and lower polymeric layers. Accidental needle sticks are reduced by optional guard fingers surrounding the needle. These fingers extend past the and bracket the sharpened end of the needle.

Abstract: The various embodiments of the invention are directed to systems for the dispensing and mixing of agents, such as paint colorants, chemicals, pharmaceuticals, or beverage additives such as sweeteners and creamers, by means of a binary array of dispensers. An array of blister dispensers is preferred.

Abstract: The present disclosure provides a method of pressurizing enclosures having bi-stable valves. The valve has an invertible element having a port therethrough, and is converted from an open mode into a closed mode by a sudden change of pressure across the valve. The method is particularly suited for pressurization of enclosures en masse.

Abstract: The various embodiments of the invention are directed to safety razor heads (120) having intrinsically fenced cutting blades (136, 138) oriented at a high slicing angle to the shaving direction. The razor comprises a plurality of short cutting edges (4) in a spaced relationship across the width of the cutting zone, bounded by leading (112) and trailing guards (104), and oriented at an angle greater than 30 degrees, resulting in enhanced cutting action, improved lubricant and debris flow, and longer life of the cutting edges. Lateral skin tensioning is achieved in one embodiment by the spreading action of left and right oriented cutting edges.

Abstract: The present invention relates to a sheath/core shoelace having enhanced knot retention and to the method of manufacture.

Abstract: The present invention relates to a method and frictive fluid composition for application to a shoelace knot, whereby the shoelace becomes more resistant to untying. The frictive fluid contains a volatile solvent and a frictive powder.

Abstract: A zipper including two stringers, each stringer having a row of coupling elements having a plurality of coupling element spacings, and at least one stringer having a plurality of coupling element widths.

Abstract: A compact lubricant reservoir for a bearing housing is provided whereby visual inspection of the reservoir indicates the level of lubricant reserve.

Abstract: The main rotor of a helicopter is driven by an epicyclic gearbox comprising a rotor sun gear coaxial and co-rotational with the rotor, a stationary sun gear coaxial with the rotor sun gear, at least one planet having an axis parallel to and rotating about the sun gear axis, and making contact with both sun gears. The planet comprises first and second planetary coaxial gears mechanically constrained to rotate together. The first planetary gear is in meshing engagement with the stationary sun gear and the second planetary gear is in meshing engagement with the rotor sun gear. The first planetary gear is also in meshing engagement with the internal teeth of a first ring gear and the second planetary gear is also in meshing engagement with the internal teeth of a second ring gear. The first and second ring gears are separately driven, and torque is combined by the planets.

Abstract: The present disclosure provides for a bi-stable valve especially useful for pressurizing pen refills. Pen refills so equipped may be inflated en masse in a pressure chamber, with a sudden drop in chamber pressure causing the bi-stable element to move from a valve open to a valve closed position.
