An ink manifold defining multiple fluid flow paths has openings arranged for detachable connection with conduits in an interface. Shut off valves at each of the openings respectively, are biased open. An actuator biased to a closed position by a resilient element, where it holds all the shut off valves closed. The actuator engages the interface such that moving the interface into connection with the openings simultaneously moves the actuator to an open position where the shut off valves are able to open. The resilient element generates a bias greater than a combined bias exerted by the shut off valves on the actuator.

An automotive exhaust system has an exhaust pipe (11) with a reduction agent inlet with dosing valve (10) upstream from a NOx selective catalytic reduction converter. In the vicinity of the valve, the exhaust pipe is shaped to minimize the direct release of heat to the valve, and / or to facilitate the direct release of heat to the valve.

The ink manifold includes a plurality of openings for detachable connection with conduits in an interface of the printer; a plurality of shut off valves at each of the openings respectively, each shut off valve having a biasing member configured for biasing each shut off valve into an open position; an actuator biased towards a closed position by a resilient element such that the actuator holds all the shut off valves closed when in the closed position. The actuator is configured for engagement with the interface such that movement of the openings into connection with the interface simultaneously moves the actuator to an open position wherein the shut off valves are held open.

The invention discloses a novel multi-wedge-shaped composite steel strip traction elevator system which comprises an elevator car side bracket, a multi-wedge-shaped composite steel strip, an elevator car, a multi-wedge-shaped composite steel strip traction machine and a counterbalancing system. The multi-wedge-shaped composite steel strip comprises a multi-wedge-shaped composite steel strip head end and a multi-wedge-shaped composite steel strip tail end. The multi-wedge-shaped composite steel strip head end is connected with the elevator car side bracket. The multi-wedge-shaped composite steel strip tail end penetrates through the bottom of the elevator car, the multi-wedge-shaped composite steel strip traction machine and the counterbalancing system. The multi-wedge-shaped composite steel strip is composed of a plurality of steel wire ropes and a coating layer made of polyurethane rubber. The coating layer coats the outer walls of the steel wire ropes, and the steel wire ropes are connected into a whole through the coating layer. The outer wall of the coating layer is a concave-convex face. A traction wheel of the multi-wedge-shaped composite steel strip traction machine is matched with the outer wall of the coating layer in shape. By the adoption of the structure, safety is further ensured, and no noise is generated; no lubricating oil or only a small amount of lubricating oil needs to be used for lubricating the polyurethane coating layer, maintenance is easy, and the novel multi-wedge-shaped composite steel strip traction elevator system is clean and environmentally friendly.

The invention discloses a Chinese medicinal oral liquid for easing a Qi-deficiency type coronary disease and a preparation method.

There is provided a method for producing a substrate (600) suitable for supporting an elongated superconducting element, wherein, e.g., a deformation process is utilized in order to form disruptive strips in a layered solid element, and where etching is used to form undercut volumes (330, 332) between an upper layer (316) and a lower layer (303) of the layered solid element. Such relatively simple steps enable providing a substrate which may be turned into a superconducting structure, such as a superconducting tape, having reduced AC losses, since the undercut volumes (330, 332) may be useful for separating layers of material. In a further embodiment, there is placed a superconducting layer on top of the upper layer (316) and / or lower layer (303), so as to provide a superconducting structure with reduced AC losses.
