Abstract: A heart valve replacement device and methods of manufacturing same are provided. The heart valve replacement device includes a substrate and a low-profile composite covering in conformal contact with the substrate and suturelessly attached to the substrate. The low-profile composite covering includes a textile base layer and a thermoplastic polymer coating integrated with the textile base layer. The thermoplastic polymer coating or select portions thereof are substantially fluid impermeable.

Abstract: A power machine can include a frame, a power source, one or more workgroup actuators, and one or more tractive assemblies secured to the multi-piece frame. The frame can include a base frame and a bridge frame. The bridge frame can support the one or more actuators and the one or more tractive assemblies relative to the base frame. The tractive assemblies can include one or more drive actuators that is supported by the bridge frame. The base frame can support the power source relative to the bridge frame.

Abstract: A loader can include a lift arm structure coupled to a frame. The lift arm structure can move between a fully-lowered position and a fully-raised position and can include a lift arm and a connecting link. A first end of the connecting link can be pivotally coupled to the frame at a first pivot point and the lift arm can be pivotally coupled to a second end of the connecting link a second pivot point. The lift arm structure can further include a lift actuator configured to pivot the lift arm about the second pivot point and an extension actuator configured to pivot the connecting link about the first pivot point. The extension and lift actuators can be controlled to move the lift arm along a variety of travel paths between any two points within a lift envelope of the lift arm structure.

Abstract: A gas/liquid transfer device for delivering a fixed quantity of pressurized gas/liquid to a dispensing device including a fixed volume chamber for receiving the pressurized gas/liquid, the chamber being in fluid connection with a system of controllable filling and emptying valves and a discharge connector. The discharge connector is disposed downstream of the emptying valve is arranged to be operatively coupled by an operator to a hand held dispensing device. The discharge connector is tamper-proof and configured to prevent a fixed quantity of pressurized gas to be discharged without the dispensing device being attached to the discharge connector. The timer is configured to impose a predetermined time interval between successive transfers of the pressurized gas/liquid.
