20090321196Asymmetric Tension Adjustment Mechanism and Head Piece Including Same - An asymmetric adjustment mechanism, a head piece (e.g., stethoscope head piece or audio headset) including such an adjustment mechanism coupled to an ear tip subassembly, and a stethoscope including such a head piece. In typical embodiments, the adjustment mechanism can be closed (e.g., to reduce separation between ear tips) by exertion of closing force on the ear tip subassembly, or opened by exertion of opening force on the ear tip subassembly. In some embodiments, it automatically locks (e.g., with a desired separation between ear tips) upon cessation of user-exerted adjustment force in a locked state in which it exerts no more than an acceptably small (e.g. zero) bias force on the ear tip subassembly. The bias force has magnitude less than that of the opening force required to separate the ear tips to remove them from the user's ears. Preferably, the adjustment mechanism closes in response to relatively low closing force on the ear tip subassembly but requires that the user exert greater opening force to open it. Some embodiments of the adjustment mechanism are configured for use (e.g., as hinges) in or with apparatus other than head pieces, such as, for example, home appliance or motor vehicle doors, non slamming house doors, springless gates, or laptop screens.12-31-2009

20140311837SAFETY BRAKE SYSTEM FOR TRAILERS - In a gaseous-fuelled stoichiometric compression ignition internal combustion engine, a pilot fuel is injected directly into the combustion chamber to help initiate a multi-point ignition. The engine provides performance improvements approaching those of high pressure direct injection engines but with less complexity because the gaseous fuel is introduced into the intake air subsystem at relatively low pressure and as a result of the stoichiometric combustion, the low oxygen content in the combustion products exiting the combustion chamber allows the use of a three-way catalyst instead of other after treatment arrangements normally associated with conventional compression ignition engines that require the addition of a reductant.10-23-2014
