Abstract: An electric motor includes a stator and a rotor rotatable relative to the stator. The rotor includes an axial shaft, a disc projecting radially from the shaft, and a ring magnet affixed to the disc. The shaft and the disc are integrally formed as a unitary body.

Abstract: Disclosed are antiseptic compositions for disinfecting tissues, in particular for ocular use. Methods and compositions disclosed herein include sodium chlorite, optionally in combination with a surfactant.

Abstract: Disclosed herein are methods and systems of preparing containment vessels which contain a precise volume of fluid. An auger filler, comprising a rotor and a stator, may dispense this precise volume of fluid into a containment vessel when the rotor is rotated relative to the stator in a first direction, causing fluid contained the auger filler to be dispensed into the containment vessel, until the precise volume of fluid is dispensed. The rotor may then be rotated relative to the stator in a second direction to prevent more fluid from being dispensed, ensuring that the containment vessel is not significantly overfilled past this precise volume of fluid. The containment vessel may then be sealed to define a prepared containment vessel. The methods and systems herein may allow for a continuous process flow that continuously produces prepared containment vessels, with each being near identical to one another.

Abstract: Anti-rotation assemblies for use with fluid valves are disclosed. An example apparatus includes a retainer collar coupled at an end of a plug, the plug including a plug collar around which the retainer collar is disposed, the plug and the retainer collar being substantially flush at an interface between the plug and the retainer collar, a fastener extending transversely through the retainer collar and the plug collar to couple the retainer collar at the end of the plug, when the retainer collar and the plug are disposed within a valve body, a stem extends through the retainer collar and the plug to enable the plug to be moved within the valve body; and an anti-rotation collar to receive the retainer collar, the anti-rotation collar coupled at an end of a cage, the anti-rotation collar and the retainer collar having corresponding non-circular cross-sections to inhibit rotation of the retainer collar and the plug when the plug is moved within the valve body.

Abstract: A habitation module with a gravity chamber that provides an artificial gravity environment. In one embodiment, the gravity chamber is annular and includes an outer cylindrical wall, an inner cylindrical structure, and opposing side walls that connect the outer cylindrical wall and the inner cylindrical structure. The gravity chamber attaches to a cylindrical core member of the habitation module with support bearings. The support bearing includes an inner race attached to the cylindrical core member, and an outer race attached to the gravity chamber. A drive mechanism drives the outer race of the support bearing to rotate the gravity chamber about an axis to simulate a gravitational force within the gravity chamber.

Abstract: A habitation module with a gravity chamber that rotates to provide an artificial gravity environment. In one embodiment, a portal chamber is installed adjacent to the gravity chamber and configured to rotate about the same axis. The portal chamber includes a brake mechanism to stop the rotation of the portal chamber, a first access opening for a crew member to pass between an interior of the habitation module and the portal chamber while rotation of the portal chamber is stopped, an engagement mechanism that engages the gravity chamber to rotate the portal chamber about the axis at a speed of the gravity chamber, and a second access opening for the crew member to pass between the portal chamber and the gravity chamber while the portal chamber rotates at the speed of the gravity chamber.

Abstract: A habitation module with a gravity chamber that provides an artificial gravity environment. In one embodiment, the gravity chamber includes an inner cylindrical structure, outer wall segments that are attachable to one another to form an outer cylindrical wall, and opposing side walls having support members that are extendable. The gravity chamber has a first diameter when the support members are contracted, and has a larger second diameter when the support members are extended. The gravity chamber connects to the habitation module with rotating attachment members so that the gravity chamber rotates about an axis. The habitation module also includes an inflatable shell that encompasses the gravity chamber.
