Abstract: A hydrogen fueling station and system for hydrogen fueled vehicles that can transfer any gaseous fuel to any vehicle and can be located in any place where a vehicle can park and where environmental, safety and other regulatory requirements permit gaseous fuel to be transferred. The hydrogen fueling station is vertically elongate and includes an enclosure that has a plurality of housings to house groups of like components. The housings are configured and positively ventilated with external air to prevent the accumulation of leaked hydrogen.

Abstract: A gas distribution system according to an embodiment includes flowing a first gas stream from a first dispensing cylinder to a receiving cylinder. When the pressure differential between the first dispensing cylinder and the receiving cylinder obtains a selected value, stopping the flow of the first gas stream, and flowing a second gas stream from a second dispensing cylinder to the receiving cylinder. When the pressure differential between the second dispensing cylinder and the receiving cylinder obtains a selected value, stopping the flow of the second gas stream, increasing the pressure of a third gas stream from the first dispensing cylinder to a pressure greater than the second dispensing cylinder pressure, and flowing the third gas stream into the second dispensing cylinder until the pressure in the second cylinder has increased to a selected value. In other embodiments, an intensifier is used to increase the pressure of a gas stream.

Abstract: In the process for the separation of substances by cooling crystallization, the mixture remaining in the crystallizer after separation of the crystal layer is removed and the crystal layer is melted. The process is distinguished in that the mixture, which completely fills the crystallizer, is set into vibration during the process of solidification by movements of oscillation imparted to it and is left in the crystallizer until a degree of solidification of from 50% to 90% has been obtained.

Abstract: Schiff's bases of the formula ##STR1## are obtained by reacting an amine H.sub.2 N--R.sub.3 with a ketone ##STR2## in presence of calcium hydrogen phosphate, apatite, aluminum oxide, aluminium hydroxide and/or Fuller's Earth and subsequent removing the water by azeotronic distillation.The products are intermediates for the preparation of phenylene diamines which may be used as age resistors for rubber.

Abstract: Catalyst consisting of a reaction product of a copper compound with N-methyl-pyrrolidone which accelerates the reaction of nitrochlorobenzenes with aromatic amines.
