A mixing device includes a base, shaft, impeller sleeve, and impeller blades. The base can be constructed for releasable attachment to an opening of a container, such as a 55-gallon drum. The shaft extends from the base and is coupled thereto such that rotation can be transmitted to the shaft by way of or through the base. The impeller sleeve is mounted on the shaft and supports the impeller blades. Each impeller blade includes an attachment leg and a stirring leg extending from the attachment leg. The impeller blades are supported so as to transition from a collapsed position with the stirring leg proximal to a central axis of the shaft to an extended position with the stirring leg distal from the central axis when the shaft is rotated. Each impeller blade can be formed of a plastic, such as a glass-filled polypropylene or glass-filled nylon.

An animal trap sensor includes a base having a distal end and a proximal end, a switch having a first metallic element and a second metallic element, and a signal unit, in which, when the first metallic element contacting the second metallic element, thereby forming a closed circuit, such that the signal unit transmits a signal to an off-site receiver Or, an animal trap sensor includes a first portion and a second portion electrically connected with a signal unit including a power supply, in which, when the first and the second portions are disposed at a first distance between each other, thereby generating an output property, in which, when the first and the second portions are disposed at a second distance between each other, which is different from the first distance, thereby changing the output property and causing the signal unit to transmit a signal to an off-site receiver

A quick-disconnect mixer drive system includes a drive adapted to be mounted on a mixing tank. The drive includes an output shaft; a first quick-disconnect coupling component mounted on the output shaft; and a second quick-disconnect coupling component adapted to be mounted on a mixing shaft of an associated mixing tank. The second quick-disconnect coupling component being shaped to engage the first quick-disconnect coupling component to transmit both clockwise and counterclockwise torque from the output shaft to the mixing shaft and resist relative longitudinal movement between the first and second quick-disconnect coupling components.

Quick-disconnect mixer drive system

An aircraft flight control surface has an actuator that employs a magneto-rheological (MR) fluid for dynamically adjusting the responsiveness of the control surface. The MR fluid may be used as a primary or secondary control in the event that a primary control actuator fails. In the event of system failures associated with the primary control, an alternate level of performance may be provided by the secondary control and communicated to the overall flight control system. This permits the control surface actuator to reactively and proactively respond to changes associated with the flight control system. If the design fails, it also permits a safe mode of operation should the ability to dynamically adjust the viscosity of the MR fluid be negatively impacted. The safe mode of operation may involve a reduced level of performance.

A container for storing and transporting field controllable fluid is disclosed. The field controllable material may be mixed and remixed in the container and the field controllable material may be flowed into or discharged from the container chamber without opening the container.

Container for transporting and storing field controllable fluid

A container (12) for storing and transporting field controllable fluid is disclosed. The field controllable material (14) may be mixed and remixed in the container (12) and the field controllable material (14) may be flowed into or discharged from the container chamber without opening the container. Said container is used in the method of making a magnetorheological device.
