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 peanut butter mixer system including: a screw-mixer formed as a continuous rod member having sequential looped coils along a length of said continuous rod member and terminating with a cutting edge; wherein said screw-mixer is powered via a motor and a powerer as manipulated by a user-operator to re-mix peanut butter in a provided container. The screw-mixer is powered via the motor and powerer as manipulated by a user-operator.

Present invention creatively makes convenient for any person using beverage to blend powder with liquid uniformly without use of shaking motion or battery and thereby preventing from spilling and running out batteries. Invention of unique reverse planetary gears system and side arm stirrer with window paddle has made possible convert torque of finger to multiple rotation of stirrer in order achieve efficient uniform blending. Moreover, this invention takes full advantage of removable snap mechanism to assemble and disassemble protein blender cup which is very necessary for washing every single parts to achieve highest sanitization. In short, this invention helps consumer to have protein blender cup which doesn't require shaking or battery and can be completely sanitized without any struggle.

The present invention is a device and a method that combines a carbon disulfide-releasing chemical with a low pH organic or inorganic acid to produce a carbon disulfide-containing fluid at or near the point of injection that minimizes or eliminates the possible exposure of carbon disulfide to workers and the environment. In one particular embodiment a positive displacement injection pump injects the carbon disulfide-containing fluid into a crude oil system for treating crude oil transmission lines and in downhole tubulars to remove paraffin deposits. The device uses a unique in-line motion mixer to mix two fluids. The device is electronically controlled locally and remotely with the system operating data displayed locally and transmitted remotely. The paraffin treating carbon disulfide-containing fluid and supplemental chemicals dissolve, disperse and remove paraffin deposits.

A method for processing a fluid includes removably securing a retention member to a vessel that bounds a chamber; inserting a collapsible bag within the chamber of the vessel; securing the bag to the retention member so that the bag is supported within the chamber of the vessel; and dispensing a fluid into a compartment of the collapsible bag supported within the chamber of the vessel. The fluid can be mixed within bag while the bag is disposed within the vessel.

A drive sub-assembly includes a hub extending from a first end face to a second end face along a longitudinal axis. The hub may have an outer circumferential surface arranged to engage a first bearing assembly and an inner circumferential surface arranged to engage an output shaft. The drive sub-assembly further includes a gear attached to the second end face of the hub. The gear may have a second inner circumferential surface that is arranged to directly engage a second bearing assembly.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment; a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.

An implement attachment holder for a hand mixer includes a body defining opposed first and second surfaces and first and second mounting projections coupled with the body and extending away from the first surface of the body at respective first and second locations spaced apart at a first distance along a first direction. The attachment holder further includes a device retention projection extending away from the second surface of the body and partially along the first surface to at least partially overlie the first and second locations from which the first and second mounting projections extend. The device retention projection further defines at least three attachment channels extending in a second direction normal to the first direction at spaced-apart locations along the device retention projection.
