Abstract: A fluid containment layer adapted to be used in a pad for absorption, containment, and/or controlled release of liquid or gel, where the fluid containment layer absorbs and/or holds a liquid or gel, such as a disinfecting liquid or gel. The fluid containment layer is resilient and returns to its original shape upon pressure applied thereto. The fluid containment layer includes generally vertically oriented fibers. The fluid containment layer may be used in a self-disinfecting pad.

Abstract: An improved approach toward the electrostatic deposition of activatable adhesive formulations is disclosed. The activatable adhesive formulations are formed for transforming from a dry powder precursor layer to a precursor layer film.

Abstract: An improved approach toward manufacture of a sealed fuel cell stack configuration including electrostatic deposition of materials onto substrate surfaces of the fuel cell stack.

Abstract: A system for supplying fuel to an internal combustion engine. The system comprises a first fuel pump, which is designed to deliver fuel from a reservoir to the internal combustion engine. The system furthermore comprises a suction jet pump which is designed to fill the reservoir with fuel. In addition, the system comprises a second fuel pump which is designed to operate the suction jet pump. The system furthermore comprises a control unit which is designed to operate the second fuel pump if a fuel fill level falls below a predefinable threshold value.

Abstract: Suction jet pumps include a driving line which leads via a jet outlet into a suction chamber, where the suction chamber has a suction opening which interacts with a valve element and through which fluid is sucked into the suction chamber. The valve element together with the suction opening forms a suction valve. The suction jet pump is driven by a driving stream flowing via the driving line. The suction jet pump is arranged in a storage tank and sucks fuel out of a fuel tank into the storage tank. The driving line has a bypass opening which leads into the suction chamber and is arranged in such a manner that the bypass stream thereof acts on the valve element.

Abstract: Suction jet pumps are already known with a driving line which leads via a jet outlet into a suction chamber, where the suction chamber has a suction opening which interacts with a valve element and through which fluid can be sucked into the suction chamber. The valve element together with the suction opening forms a suction valve. The suction jet pump is driven by a driving stream flowing via the driving line. The suction jet pump is arranged in a storage tank and sucks fuel out of a fuel tank into the storage tank. At low levels in the fuel tank, air may sometimes be sucked up and conducted into the storage tank, as a result of which foaming occurs in the storage tank. However, the large volume of the foam causes fuel to be displaced, which may result in partial emptying of the storage tank. This effect is also referred to as dynamic leakage. A characteristic curve of the suction jet pump that represents the suction power as a function of the driving stream has a comparatively steep gradient.

Abstract: An air spring has a roll-off piston (1) and a rolling-lobe flexible member (2) of rubber or rubber-like material. At least the opening of the rolling-lobe flexible member, which lies opposite the opening assigned to the roll-off piston (1), is closed air tight with an attachment part (3) and the attachment part has a planar connecting region (4) having at least one air connection (7) and an outer rim (11) and a conical region (10) facing toward the rolling-lobe flexible member (2). The rolling-lobe flexible member (2) is tightly vulcanized to the attachment part (3) in a vulcanization region (12) which extends from the side (9) of the outer rim (11) into the conical region (10). The side (9) of the outer rim (11) faces toward the rolling-lobe flexible member (2). The at least one attachment part (3), which is vulcanized to the rolling-lobe flexible member (2), is configured as a head plate (3) complete with all connections (7) and is made of thermoplastic or duroplastic synthetic material.
