A tattoo ink mixing apparatus has a housing having a cavity, a plunger movable between a first position and a second position, and a dynamic member disposed in the cavity and adapted to engage with the plunger distal end. The dynamic member moves in response to movement of the plunger and alternatively creates a suction force and an expulsion force in the opening of the distal end of the housing as the plunger moves between its first and second positions.

A concrete vibrator can further reduce vibration. The concrete vibrator includes a motor, a flexible shaft drivable by the motor, an unbalanced weight drivable with the flexible shaft, a flexible hose at least partially covering the unbalanced weight and the flexible shaft, a body housing accommodating the motor, and an elastic member between the body housing and the flexible hose.

The present invention involves the use of a small profile device for preparation and/or delivery of cold slurry into the human body. The cold slurry can be generated within the device itself or within a separate small chamber, both of which produce a cold slurry using a cooling source and an injectable fluid. The delivery device provides continued agitation to the fluid/slurry through rotation and/or vibration of blades within the device. The fluid/cold slurry is cooled/kept cool through the use of an external cooling device, such as a cooling sleeve, that at least partially surrounds the delivery device. The cooling sleeve can cool or maintain the temperature of the cold slurry through a number of mechanisms. The cold slurry can be delivered using a device in accordance with the present invention to any tissue inside the body, including subcutaneous fat, visceral fat, and brown fat.

The present invention relates to an equipment and method for producing polymer pellets which comprise one or more polymer components and one or more further components, wherein in said process at least one of said one or more further components is incorporated into pellets by applying a liquid, which comprises said at least one component, onto said pellets.

A handheld mixing vessel, with removable lid, operatively containing a whisk and infuser enclosed system and a strainer to keep contents from flowing through the mouth opening at the top of the bottle. A hollow agitator positioned operatively near the top of the bottle and sits near the bottom of the bottle and thereby mixes fluid contained within the vessel, infuses fluid in the vessel and strains contents as they are poured out. An embodiment wherein a hand shaken motion will allow the whisk to mix and combine contents inside the structure. The enclosed feature of the mixing component allows for other uses such as but not limited to infusing tea, fruit, ice or other contents. The structure is also easy to clean and not mechanically complex. While also demonstrating the benefits of less noise created by no contact with the walls of the mixing structure and thus, avoiding the possibility of breakdown, scratching or other damage internally from contact.

A flow disturbance apparatus includes: a refrigerant pipe having a flow space in which refrigerant flows; and at least one disturbance member disposed inside the refrigerant pipe that is vibrated by the flow of refrigerant in the refrigerant pipe to disturb the refrigerant flowing in the refrigerant pipe.

A material sprayer includes a hopper and a shaker assembly mounted onto a sidewall of the hopper. The hopper includes at least one sidewall that extends along a first plane. The shaker assembly includes a resilient bracket, an electromagnetic coil, and an armature. The resilient bracket is mounted to the sidewall of the hopper and includes first and second ends and a curved portion. The electromagnetic coil is mounted to a portion of the resilient bracket and is configured to generate a magnetic field in response to a current from a power source. The armature is mounted to a portion of the resilient bracket such that the armature is able to move relative to the electromagnetic coil along an acceleration axis that is orthogonal to the first plane of the sidewall of the hopper.
