Abstract: A main rotor blade assembly with a high negative pitching moment airfoil section having a pitching moment coefficient beyond (more negative than) ?0.035 at Mach Numbers below 0.80 and a blade taper of 1:5 or greater.. The main rotor blade preferably limits blade torsional bending and an aft loaded tip airfoils to approximately ‘no more’ than that of conventional effective rotor blade designs based on conventional tip airfoil sections.

Abstract: An electrically heated cigarette smoking system includes a cigarette that is formed with a tobacco rod portion, a filter tube portion, a tobacco mat layer wrapped around the tobacco rod portion and the filter tube portion with opposite ends of the tobacco mat layer abutting along a seam parallel to the central axis of the cigarette and cigarette paper wrapped around the tobacco mat layer and bonded to itself along an overlapped seam that is offset from the seam of the tobacco mat layer. The method of manufacturing the cigarette includes wrapping the tobacco mat layer and the cigarette paper around the tobacco rod portion and the filter tube portion on a single, high-speed machine.

Abstract: A main rotor blade incorporating a rotor blade tip region having a tip chord and a tip taper such that the ratio of the main rotor blade chord to the tip chord is approximately 0.30. The tip taper ratio preferably providing an approximately 28% area of reduction in said outer 10% of said blade span.

Abstract: A main rotor blade exhibiting a unique planform shape in which the blade chord increases from the root end of the blade inboard region to the outer main region of the blade, where the blade chord achieves a maximum chord at a spanwise location within the main region, then decreases toward a distal tip end. The leading edge preferably is generally straight while the trailing edge is contoured to define the chord. Another characteristic feature of the rotor blade design is the location of the blade-feathering axis in which the feathering axis is located at a mid chord position over some inboard length of the rotor blade then transitions to a quarter chord location. Another characteristic feature is an airfoil distribution along the blade span that transitions from a blunt trailing edge to a sharp trailing edge airfoil suited for mid-range Mach number operation. The tip region preferably utilizes a transonic flow airfoil.

Abstract: The present invention relates in part to a method of manufacturing zinc-glycerol complexes and the zinc-glycerol complexes so produced, which unexpectedly results in microfine zinc-glycerol complex particles which have a mean particle length (i.e., major axis) of less than about 1.0 micron. The zinc-glycerol complex particles of the invention also generally maintain a hexagonal crystalline structure, thereby retaining superior lubricity and tactile properties. The invention also provides pharmaceutical and/or therapeutic compositions comprising microfine zinc-glycerol complex particles, and methods for using such compositions.

Abstract: A multi-element rotor blade includes an individually controllable main element and fixed aerodynamic surface in an aerodynamically efficient location relative to the main element. The main element is controlled to locate the fixed aerodynamic surface in a position to increase lift and/or reduce drag upon the main element at various azimuthal positions during rotation.

Abstract: A pneumatic valve module for a train railcar. The pneumatic valve module operates in an electronically-controlled mode or in a conventional pneumatic controlled mode. In either mode, the valve module is responsive to a pneumatic emergency brake signal for making an emergency brake application. Also, in the electronically-controlled mode an electronic signal (supplied over a conductor or a wireless communications link) commands a controller on each railcar to apply or release the brakes. In the pneumatic-controlled mode, various reservoir pressures are measured to apply and release the brakes in response to the measured pressures.
