Abstract: A gripping device for being suspended from a load handling device for lifting and moving containers stacked in stacks in a grid storage structure including a plurality of tracks arranged in a grid pattern above the stacks of containers. The gripping device including a frame and at least one gripping assembly mounted on the frame. The gripping assembly including at least two grippers, each gripper being configured to engage a container located below the frame. Each gripper is movable between a gripping position for gripping the container and a release position for releasing the container. The gripping device further including a single linear actuator coupled to the at least two grippers by a linkage assembly such that actuation of the single linear actuator drives the at least two grippers substantially simultaneously between the gripping and release positions.

Abstract: A vaporizer device including a vaporizer cartridge configured to efficiently and effectively heat a non-liquid vaporizable material is described. The vaporizer cartridge may include a heating element configured to vaporize the vaporizable material by delivery of heat to the vaporizable material. The cartridge may include a cartridge contact in electrical communication with the heating element. The cartridge contact may be configured to couple to a receptacle contact along a vaporizer body of the vaporizer device having a power source to allow power to pass from the power source to the heating element. The heating element can include electrically resistive features such that current traveling along the heating element can cause the heating element to increase in temperature to within a desired temperature range. Related systems, methods, and articles of manufacture are also described.

Abstract: The instant invention describes a device and system for dispensing microbial solutions into a wastewater treatment environment. The device contains one or more removable modules that provides the user with the capability of quickly and easily removing one or more of the modules without the need for replacing or removing the entire unit. The modules are preferably designed to hold bags filled with a microbial solution. The bags are fluidly connected to a pump which dispenses the solution to a predetermined location.

Abstract: The present invention is directed toward a device and method of dispensing biological solutions into a wastewater treatment system containing a floating mixer adapted to dispense biological solutions. The floating mixer with dispensing capabilities is strategically positioned within water holding areas, such as ponds or lagoons. The floating mixer and dispensing unit contain a flotation platform or other support structure, an impeller or similar device to create a flow pattern, and a dispensing device for controllably dispensing a microbial, preferably bacterial, solution.
