A chemical mixer tool for use in a storage drum is described. The chemical mixer tool typically comprises a mixer housing assembly in which one end of a mixer shaft is secured, the distal end of the mixer shaft having at least one collapsible impeller assembly removably attached thereon. The chemical mixer tool is configured to be removably secured to the top portion of the storage drum, with the distal end of the mixing shaft extending into the interior of the storage drum.

There is provided apparatus (301) for mixing contents of a receptacle, the apparatus comprising a rotary shaft (302) equipped at a proximal end with a connection for removable attachment to a means of providing rotation. The rotary shaft has a mixing element (303) fixedly connected at a distal end of the shaft opposite to said proximal end. The mixing element comprises at least two arms (304) at the distal most end of the shaft, a corkscrew neck (306) on the shaft and a collar (305) on the shaft positioned in between the at least two arms and the corkscrew neck. The at least two arms are configured in a first partially-open resting position and are moveable to a second fully-open operative position. The mixing element further comprises a blade (307) positioned across the shaft more proximally than the corkscrew neck.

Magnetic stir bar having at least one permanent magnet to spin the magnetic stir bar when the magnetic stir bar is subjected to a rotating magnetic field. The magnetic stir bar has a chamber to store a product within the magnetic stir bar. The magnetic stir bar has a closed configuration in which the chamber is closed and an open configuration in which the chamber is open. The magnetic stir bar automatically reconfigures itself from the closed configuration to the open configuration when said magnetic stir bar is spun at or above a threshold rotational speed.

A mixer apparatus for mixing a high-viscosity fluid has a mixer shaft with a plurality of blades affixed thereto, a hydraulic motor drivingly connected to the mixer shaft so as to rotate the mixer shaft, a hydraulic pump connected by a fluid circuit to the hydraulic motor so as to deliver hydraulic fluid under pressure to the hydraulic motor, an electric motor drivingly connected to the hydraulic pump, and a hydraulic fluid reservoir connected to the fluid circuit so as to supply hydraulic fluid to the hydraulic pump. The plurality of blades are pivotally mounted to the mixer shaft.

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.
