Abstract: The liquid ink writing instrument of the invention has a body containing, from its rear end towards its front end, a reservoir for the ink and a front chamber containing a capillary element for transferring ink coming from the reservoir to a writing head, which head is fed with ink by the capillary element and projects from the front portion of the body. The reservoir (3) is separated from the front chamber (6) by a flexible wall having shape memory and provided with slots (16), acting as a valve (13) suitable for opening when the ratio (A) of the pressure (P1) inside the reservoir (3) over the pressure (P2) inside the volume of the front chamber,(6) facing said valve (13) exceeds a first value (A1), and of reclosing instantly as soon as said ratio (A) becomes less than or equal to a second value (A2), the valve releasing the ink in the form of a jet directed towards the rear face (7a) of the capillary element (7). The instrument includes means for pressurizing the reservoir. The front chamber communicates with ambient air. The first value (A1) of the ratio (A) of the pressures (P1/P2) is preferably about 1.07, and the second value (A2) of said ratio (A) is preferably about 1.05.

Granted: 2010-08-03
Abstract: A vehicle comprises a frame and a slide rail disposed below the frame for guiding a drive track along a road surface. An arm has a first portion pivotally coupled to the frame at a frame pivot location and a second portion pivotally coupled to the slide rail at a rail pivot location. Vertical movement of the slide rail causes a length of the arm between the frame pivot location and the rail pivot location to extend or contract. The vehicle suspension system becomes increasingly stiffer as the deflection of the slide rail increases, to contribute to a more comfortable ride and to reduce the risk of bottoming- out.

Abstract: A valve assembly can automatically dispense aerosol content from an aerosol container (12) at predetermined intervals without the use of electric power. A  diaphragm (40) at least partially defines an accumulation chamber (36) that receives gas propellant from a portion of the can (12) during an accumulation phase. Once the internal pressure of the accumulation chamber (36) reaches a predetermined threshold, the diaphragm moves, carrying with it a seal so as to unseal an outlet channel (51), and thereby initiate a spray burst of the main active chemical. The diaphragm (40) assumes its original position when the pressure within the accumulation chamber (36) falls below a threshold pressure.
