A hydraulic unit includes a tank configured to be filled with a hydraulic fluid. The tank has at least one inflow connection and at least one outflow connection. A flow guide for the hydraulic fluid is formed between the inflow connection and the outflow connection. The flow guide is configured to have at least two 180 flow arcs configured to cool and calm the hydraulic fluid and to avoid dead zones.

Water storage systems are provided to facilitate storing water for use when a primary source of water becomes unavailable. These water storage systems can be configured to connect into a home's or a building's plumbing to enable the water tanks of the system to be easily filled and regenerated. The water storage systems may include a support system to maximize space utilization and to possibly provide seismic protection.

A photolithography system includes a variable-volume buffer tank, a dispensing system connected to the buffer tank, and a valve configured to release gas from a head space of the buffer tank while blocking the release of liquid from the head space. A storage container has an opening at the bottom and drains to the buffer tank through that opening. The buffer tank has a storage capacity sufficient to receive the full contents of the storage container. The system supplies chemical solutions to the dispensing system while keeping the chemical solutions from contact with air and other gases.

A communication interface apparatus in a tank gauging system. The communication interface includes a memory and a processor couple to the memory. The processor communicates using a control application with a tank inventory system that operates over a serial connection; and communicates using a wireless application with tank gauging equipment that operates over a wireless connection

The invention described herein relates to reservoirs within appliances. The present invention includes a reservoir having one or more tanks having adaptors and tubing which may be thermally welded, crosslinked, and/or overmolded. Particular embodiments of the present invention include reservoirs, reservoir systems including a reservoir, processes for forming a reservoir, and processes for forming the aforementioned reservoir systems.

A method of supplying a chemical solution to a photolithography system. The chemical solution is pumped from a variable-volume buffer tank. The pumped chemical solution is dispensed in a spin-coater. The variable-volume buffer tank is refilled by emptying a storage container filled with the chemical solution into the variable-volume buffer tank.

The disclosure relates to monitoring systems and methods. A first aspect relates to a monitoring system for use when loading fluid from a source tank to a destination tank via a loader apparatus, the monitoring system having: a first input for coupling to the source tank in order to receive a source tank input signal; a second input for coupling to the destination tank in order to receive a destination tank input signal; a sensor input for receiving a sensor signal from a fill level sensor in the destination tank; circuitry configured to determine: a first status of an electrical continuity between the loader apparatus and the source tank in accordance with the source tank input signal, a second status of an electrical continuity between the loader apparatus and the destination tank in accordance with the destination tank input signal, and a fill level status in accordance with the sensor signal; and a single user interface for displaying the first status, second status and fill level status.

The present invention materially enhances the quality of the environment and mankind by contributing to the restoration or maintenance of the basic life-sustaining natural elements. The present invention reduces the amount of carbon monoxide introduced to the atmosphere of a combustion system. This is achieved by furnishing a systems approach to optimize the amount of oxygen to be chemically combined with fuel upon ignition of both allowing the correct amount of carbon to combine with the correct amount of oxygen thus fully release the thermal energy stored therein. By so furnishing the level of oxygen with carbon of the fuel, more carbon dioxide is produced thus proportionally reduces the amount of carbon monoxide released to the atmosphere. The present invention provides a heating system that surpasses the net and gross efficiency performance of a natural gas burner.
