Flange for a vacuum apparatus comprises a housing to be connected to the vacuum apparatus defining an opening wherein the opening has rectangular narrow shape. The flange further comprises a metal seal arranged around the opening to create a vacuum tight seal.

An apparatus for forming a vacuum in a sealed enclosure through an electrochemical reaction includes an electrochemical cell comprising a cathode and an anode supported on a solid electrolyte. The solid electrolyte is a Li-ion non-volatile electrolyte containing a dissolved metal salt. The cathode is constructed of a material with which lithium is known to form alloys. The anode is constructed of a lithium-ion containing material. The cell is operable to expose lithium metal on the cathode.

A liquid petroleum gas (LPG) fuel supply system for a vehicle having an internal combustion engine includes an LPG tank, a fuel pump housing, a fuel pump inside the fuel pump housing, a fuel supply line connected between the LPG tank and the fuel pump housing, and a vapor release port located on the fuel pump housing. The vapor release port is connected to the LPG tank by a vapor return line. The fuel pump housing fills with LPG from the LPG tank under the action of gravity. Vapor forms in the fuel pump housing, separates from the liquid, gathers toward the top of the fuel pump housing, and under the action of gravity, displaces through the vapor port, rises through the vapor return conduit, and is released into the LPG tank 19, balancing pressure and preventing vapor lock.

A method of detecting specific gas species in an ion trap, the specific gas species initially being a trace component of a first low concentration in the volume of gas, includes ionizing the gas including the specific gas species, thereby creating specific ion species. The method further includes producing an electrostatic potential in which the specific ion species are confined in the ion trap to trajectories. The method also includes exciting confined specific ion species with an AC excitation source having an excitation frequency, scanning the excitation frequency of the AC excitation source to eject the specific ion species from the ion trap, and detecting the ejected specific ion species. The method further includes increasing the concentration of the specific ion species within the ion trap relative to the first low concentration prior to scanning the excitation frequency that ejects the ions of the specific gas species.
