20100083915 | Electrochemical combustion actuator - An electromechanical actuator includes a cylinder and piston for driving a load and defining a chamber in which is disposed a buffer gas, such as nitrogen, and a solid or water-based electrolyte, and electrodes for generating hydrogen and oxygen by electrolysis that mixes with the buffer gas serving to control the combustion pressure profile, and into which chamber, above the electrolyte, is inserted an igniter for combusting the hydrogen and oxygen for creating high pressures in the chamber to move the piston and create efficient mechanical work. | 04-08-2010 |
20110064579 | Active Twist Hollow Beam System - A system for actively controlling the span-wise rotational twist of a hollow beam along its longitudinal axis, including a hollow beam structure having a leading edge and a trailing edge region, the beam being split along its length, an actuator arranged between split surfaces of the beam, the actuator adapted to move the split surfaces in a longitudinal direction relative to each other, inducing a twist in the beam. In one embodiment, the actuator is a plurality of thermal expansion material blocks alternating with mechanical compression blocks, the thermal expansion material blocks being heated to cause expansion in the spanwise longitudinal direction. Other alternative actuators include a rotary actuators such as a threaded screw, piezoelectric or magnetostrictive blocks, a hydraulic actuator, or a pneumatic actuator. In an embodiment, the beam is an airfoil shape. | 03-17-2011 |
20130064666 | ACTIVE TWIST HOLLOW BEAM SYSTEM - A system for actively controlling the span-wise rotational twist of a hollow beam along its longitudinal axis, including a hollow beam structure having a leading edge and a trailing edge region, the beam being split along its length, an actuator arranged between split surfaces of the beam, the actuator adapted to move the split surfaces in a longitudinal direction relative to each other, inducing a twist in the beam. The hollow beam is affixed to an external structure at one or both ends, with only the zero warping displacement points of the beam being attached to the external structure, material or device. In one embodiment, the actuator is a plurality of solid blocks with high thermal expansion coefficients arranged between frames of the split surfaces of the beam, with alternating blocks being heated by resistance heaters to cause expansion in the spanwise longitudinal direction. | 03-14-2013 |

20140011926 | RUBBER COMPOSITION, METHOD FOR ITS FORMATION, AND AUTOMOTIVE TIRE CONTAINING THE COMPOSITION - A rubber composition with disperse phase particles containing poly(phenylene ether) can be formed by a method that includes melt blending an uncured rubber with a poly(phenylene ether) composition containing a poly(phenylene ether) and an oil to form an uncured rubber composition, then curing the uncured rubber composition. Before being blended with the rubber, the poly(phenylene ether) composition exhibits a glass transition temperature of about 40 to about 140° C., and during blending with the rubber, the oil component of poly(phenylene ether) composition migrates from the poly(phenylene ether) composition to the rubber, leaving a poly(phenylene ether)-containing disperse phase that gives rise to a second hysteresis peak temperature of about 160 to about 220° C. as measured by dynamic mechanical analysis of the cured rubber composition. Also described are the poly(phenylene ether) composition used in the method, a cured rubber composition formed by the method, and a tire containing the cured rubber composition. | 01-09-2014 |
