摘要： A pump for non-flammable liquids has an improved mounting for the motor which facilitates the relatively quick and easy removal of the motor from the pump. The pump has a main body which is hollow and cylindrical. A motor housing is connected to the main body by threads at a first end and has a removable end cap on its second end. The electric motor is located in said motor housing and secured when the end cap is on the motor housing. An electronics housing has a battery adapter plate, a switch, and a discharge port, and encloses wires and electronics such that the motor pumps the liquid from the end cap, through the motor housing and the main body, and out of the discharge port when the switch is turned on.

摘要： Blood pump assemblies and methods of manufacturing and operating blood pump assemblies are provided. The blood pump assembly includes a pump and an impeller blade rotatably coupled to the pump. The blood pump assembly also includes a pump housing component sized for passage through a body lumen and coupled to the pump. The pump housing component includes a peripheral wall extending about a rotation axis of the impeller blade. The peripheral wall includes an inner peripheral wall surface and an outer peripheral wall surface. The peripheral wall also includes one or more blood exhaust apertures. Each blood exhaust aperture in the one or more blood exhaust apertures is defined by an inner aperture edge and an outer aperture edge. Each inner aperture edge is chamfered between the inner peripheral wall surface and the outer peripheral wall surface.

摘要： A method of controlling a liquid movement system, such as a pool system. The method includes receiving a maximum time that an auxiliary load is to operate, receiving a minimum pump speed of a pump system that pumps a liquid through the auxiliary load, monitoring the time that an auxiliary load has been in operation, monitoring the pump speed of a pump system that pumps a liquid through the auxiliary load, and deactivating the auxiliary load if the maximum time or minimum pump speed has been met. Also disclosed are a pool system and a controller for controlling the pool system.

摘要： Implementations of an enhanced axial air mover system address various issues such as drying performance, transportability, storage, use, and assembly. Some implementations include ergonomic positioning of a carrying handle relative to positioning of a fan-assembly to make the system easier to carry. Enclosures with variable diameter profiles increase air flow performance. A floor edge allows for flush positioning of the air mover's outlet to improve flow of air. Various supports and engagement members allow for horizontal and/or vertical engagement of a plurality of the air movers for storage or increased air moving capacity for a given application. An alignment guide assists with positioning of the air mover with respect to a room wall to enhance air flow within the room. A cord retaining system provides an enhanced approach for securing the air mover's electrical cord. Grill guards have slotted ends to assist with assembly of the air mover.

摘要： The catheter device comprises a drive shaft connected to a motor, and a rotor mounted on the drive shaft at the distal end section. The rotor has a frame structure which is formed by a screw-like boundary frame and rotor struts extending radially inwards from the boundary frame. The rotor struts are fastened to the drive shaft by their ends opposite the boundary frame. Between the boundary frame and the drive shaft extends an elastic covering. The frame structure is made of an elastic material such that, after forced compression, the rotor unfolds automatically.
