Abstract: A surge prevention valve may be used to prevent the formation of an initial surge of high pressure. The valve may be located, for example, between a high pressure gas cylinder and a medical pressure regulator. The valve is provided with first and second valves located within a housing and integrating a pressurization orifice.

Abstract: A fueling and associated vapor recovery system maintains the same, or lower, vacuum level in the vapor hose during ORVR vehicle refueling as that seen during a non-ORVR refueling. A valve assembly is made as either a part of the end of the vapor recovery hose assembly, a separate unit that is placed between the hose assembly and the nozzle, or incorporated directly into the nozzle. The valve assembly is biased to one position by a spring to which is attached a sliding valve member.

When refueling an ORVR vehicle, the elevated vacuum level moves the valve member to a second position which blocks off the vapor hose from the vacuum pump and opens up the vapor hose to the air bleed hole.

Abstract: A chill casting and foam casting method together with a casting mold that is closable in a pressure-tight manner for producing molded articles. To improve the chill casting method and the foam casting method so that the quality of the products produced is greatly increased and particularly homogeneous material properties are achieved, a gas is supplied to a melt which only partially fills a closed mold cavity until the inside pressure within the mold cavity exceeds the melting point pressure curve such that the melt suddenly solidifies. The solidification process takes place largely independently of location and is thus sudden, so that the instantaneous state of the melt is reflected in the resulting solidified article with virtually no change. This makes it possible to produce molded articles which have a uniform core distribution and meet high quality demands in a reliable and reproducible manner.
