摘要： A system for improving yaw control at low speeds consists of one strake placed on the upper portion of the fuselage facing the retreating rotor blade and another strake placed on the lower portion of the fuselage facing the advancing rotor blade. These strakes spoil the airflow on the helicopter tail boom during hover, low speed flight and right or left sidewards flight so that less side thrust is required from the tail rotor.

摘要： An ultraviolet light absorbing polyester resin and toner particles incorporating such polymer are provided. The toner particles are particularly useful in photolithographic applications wherein ultraviolet light is used for making printing plates from color separation transparencies which contain imaged areas defined by the toner particles. The toner particles can be prepared, if desired, in finely divided form capable of forming high resolution electrographic images, and the toner particles can be used in dry or liquid developer formulation. The toner particles are heat fusible preferably at low temperatures, resist toner offset, and have good cohesivity.

摘要： The invention provides rolls, belts and other biasable members having at least one layer or coating of an elastomeric resilient crosslinked polyurethane formed by reacting (a) a polyisocyanate prepolymer comprising the reaction product of an aliphatic polyisocyanate and a polyether polyol, specifically a polyalkylene glycol in which the alkylene group contains 2 to 3 carbon atoms, and (b) a hardening mixture comprising a polyether polyol of (a) and, as a conductivity control agent, from 0.01 to 3.0 weight percent based on the total weight of (b) of a complex of an oligoethylene glycol selected from the group consisting of di-, tri- and tetraethylene glycol with an ionizable alkali metal salt selected from the group consisting of sodium iodide, lithium iodide and sodium thiocyanate.The resistivity of the elastomeric resilient polyurethane coating on the biasable member is controlled or adjusted to within a desired level of resistivity due to the inclusion of the conductivity control agent in the crosslinked polyurethane elastomer. Additionally, the inclusion of the conductivity control agent in the crosslinked polyurethane elastomer reduces the sensitivity of the resistivity of the polyurethane coating on the biasable member to changes in relative humidity. Further, since the conductivity control agent is copolymerized with the polyisocyanate prepolymers and polyols used to make the elastomeric polyurethane coatings of the biasable members of the invention, the conductivity control agent is bonded covalently to the backbone and/or the crosslinking portion of the polyurethane elastomer where it forms a permanently fixed part of the crosslinked polymer and will not migrate therefrom resulting in a continuous change in the resistivity of the polyurethane coating over time and possible adverse affects on materials that may come into contact with the migrating agent. The utility of such biasable members is in the transfer of toner images from a photoconductor to a final support sheet where the member, for example, a bias transfer roll, electrically cooperates with a photoconductor to establish a directional force field therebetween.

摘要： An anatomically form-fitting generally self-adjusting disposable absorbent garment and methods of integrating and using the garment. The garment comprises a breathable elastomeric nonwoven fabric outer cover resiliently stretchable in cross-body direction, including a pair of leg openings, front and rear waist sections fastenable with one another defining a waist opening, a crotch section situated between the leg openings and opposing front and rear panels separated by the crotch section. An absorbent insert structure is substantially superposable on the front and rear panels and the crotch section, including a liquid impermeable barrier, a liquid permeable body side liner and an absorbent composite disposed therebetween. The absorbent insert has opposed longitudinal ends which are attached to the outer cover by bonds or snaps at selected waist attachment zones, defining one or more free-span zones of the outer cover underlying the insert and having substantially unrestricted functional stretchability therein. The insert may also be attached along the leg openings.
