Abstract: Electrochemical cell systems (51) and electrochemical cell processes are described as applicable to power generation or electrolysis modes with systems that have a containment vessel interior space multiple electrochemical cell stack, stack inlet plenum (43) that can accommodate thermal expansion and contraction in an economical way and that can provide a substantially equivalent environment for each stack inlet as well as can include, if desired, either or all of a vessel external compression stack mount possibly configured as a cathode outlet manifold (111) configured as a stack mount, a fully accommodative thermal expansion-contraction electrochemical cell stack mount possibly configured with external springs (91), and even the possibility of an axial flow adjuster such as a gradation plate (99) for better operation.

Abstract: A material collection system is provided. The system can include a vacuum generator having a fan to develop an airflow and draw material into a conduit. The system can also include a transmission, a power source to selectively power at least one of the vacuum generator and the transmission, a variable power divider to divide a power output from the power source to the transmission and the vacuum generator, and a control system to control the variable power divider in a first mode and a second mode.

Abstract: A battery system with a large-format Li-ion battery powers attached equipment by discharging battery cells distributed among a plurality of battery packs. The discharging of the battery cells is controlled in an efficient manner while preserving the expected life of the Li-ion battery cells. Each battery pack internally supports a battery management system and may have identical components, thus supporting an architecture that easily scales to higher power/energy. Battery packs may be added or removed without intervention with a user, where one of battery packs serves as a master battery pack and the remaining battery packs serve as slave battery packs. When the master battery pack is removed, one of the slave battery packs becomes the master battery pack. Charging and discharging of the battery cells is coordinated by the master battery pack with the slave battery packs over a communication channel such as a controller area network (CAN) bus.

Abstract: Devices and methods for operating a diaphragm compressor. Embodiments of the present disclosure comprise an oil piston being driven to pressurize work oil against the diaphragm of the compressor. In embodiments, an injection pump provides a supplemental flow of work oil in the region of pressurized fluid, and such pump may be part of an actively controlled system. In embodiments, a pressure relief valve vents an overpump flow of work oil, and such valve may be variable. Embodiments provide feedback and control mechanisms, including control of the injection pump and the relief valve.

Abstract: Devices and methods for operating a diaphragm compressor system provide high output pressure and high throughput. In some force coupled embodiments, pressures on an actuator piston are balanced by high-pressure recovery or medium-pressure shuffling arrangements. In some embodiments, modular diaphragm compressors are stacked with a clamping mechanism pressing the compressor modules together. In embodiments, multiple stacks are provided as stages of a pressurization process. In embodiments, a main stage valve controls one or more pressure circuits for one or more hydraulic actuators of compressor modules. In embodiments, orifices configured for damping are incorporated to control actuator piston movement within a compressor module.

Abstract: A gutter broom is provided. The gutter broom can include a mandrel, one or more carriers, each carrier removably coupled to the mandrel, and one or more bristle strips, each bristle strip removably coupled to one of the carriers. The gutter broom components can be recyclable and modular, requiring no tools for assembly or servicing.

Abstract: A battery pack protects the internal battery pack components from the heat, e.g., heat generated during a sterilization process of an autoclave. The battery pack prevents the heat of the autoclave from damaging the battery cells and other electronic components within a battery pack housing. The battery pack may include a multi-layer thermal protection portion lining an inside surface of the walls of the battery pack housing with a combination of materials designed to limit the amount of heat to which the internal components of the battery will be exposed for the duration of a traditional autoclave sterilization cycle. Additionally, the battery pack may include a thermal protection casing around connection elements, such as wires and contacts, between a battery pack contact and the battery cells, to limit the heat rise from the heat of the autoclave in or on the connection elements of the battery pack.
