  • Patent number: 11768929
    Abstract: A lockout system for a metering pump is provided. The lockout system can include a user interface that is used to switch the pump between a locked configuration and an unlocked configuration. In the locked configuration, the operation of the pump cannot be adjusted through the user interface. In the unlocked configuration, the operation of the pump can be adjusted through the user interface. The lockout system can include a passkey notice that provides information regarding how to use the user interface to switch the pump between the locked and unlocked configurations.

  • Patent number: 11754065
    Abstract: A peristaltic pump can include a chassis and a chassis retaining portion forming a cavity. The pump can also include a rotor, a cover, and a linkage. The rotor can be disposed within the cavity such that tubing can be held between the rotor and the chassis and/or the chassis retaining portion. The linkage can couple the cover to the chassis. The linkage can include an arm. When opening the cover, the arm can pivot such that the chassis moves away from the chassis retaining portion to widen the cavity. When closing the cover, the arm can pivot such that the chassis moves toward the chassis retaining portion. When closed, a stop can restrict further movement of a corresponding member toward the chassis retaining portion.

  • Publication number: 20230088606
    Abstract: Devices and methods for controlling humidity including an aqueous saturated solution of a salt and/or a sugar in combination with an additive in which all components of the saturated solution are food grade. The device may or may not include a container, such as a flexible pouch, encasing the aqueous saturated solution and/or an absorbent pad. The pouch or other container may be made of a material which is moisture permeable and liquid impermeable, for example, and the aqueous saturated solution further comprises a thickening agent. In some embodiments, the components of the aqueous saturated salt solution are separately contained in different compartments of the device container, and a user may activate the device to mix the components together.

  • Patent number: 11485653
    Abstract: Described is a method for treating water with sodium hydroxide. The method can increase the accuracy of the volume of a stock sodium hydroxide solution that is delivered to the water being treated. The method can include pumping a concentrated aqueous sodium hydroxide stock solution with a diaphragm pumping system that has a two-part diaphragm assembly with a polymeric diaphragm overmolded onto a rigid insert. The polymeric diaphragm can be made of a fully-vulcanized ethylene propylene diene monomer rubber that is injection molded over the rigid insert.

  • Publication number: 20210054963
    Abstract: A quick mounting bracket for a pump is provided. The bracket includes a flexible handle that moves relative to stabilizer tabs. The bracket has ramped surfaces that guide a portion of the pump housing into a receiving slot of the bracket. A hinge of the handle biases the handle away from the pump such that the handle is driven to overlap the portion of the pump housing that seats into the receiving slot, thereby locking the pump onto the bracket until the handle is move to clear receiving slot and allow the pump to be removed from the bracket.
