    Abstract: A method of brazing stainless steel components to form a complex shape such as an impeller. The method includes the steps of providing the stainless steel components shaped and formed from a selected stainless steel alloy; providing a brazing alloy having a selected composition and compatibility with stainless steel; heating the stainless steel components and brazing alloy for a controlled time to a liquidus temperature to effect brazing; cooling the stainless steel components and brazing alloy to a quench temperature substantially lower than the liquidus temperature of the brazing alloy to provide a tensile strength of greater than about 20 Ksi in the brazing alloy; and quenching the assembly from the quench temperature to a temperature of less than about 400° F. in a given time to provide a brazed assembly free of distortion and cracks with desired mechanical properties in the stainless steel components by virtue of the thermal treatment.

    Abstract: All electromagnetic pump comprising a housing having fluid receiving and pumping chambers in communication with an inlet and outlet, respectively, an electromagnet carried by the housing external to the fluid chambers thereof, and an armature movable in the housing having a pole portion magnetically attracted by the electromagnet and a piston portion to force fluid out of the chambers and through the pump outlet. A path provides controlled bypass for bubbles in the fluid around the armature piston portion between the fluid pumping chamber and the fluid receiving chamber only during the return stroke of the armature. Fluid inertial effect is reduced by an outlet orifice provided in the fluid path from the pump outlet and by a bypass orifice in the fluid bypass path, the outlet and bypass orifices being provided either individually or in combination depending upon the fluid flow characteristics of the system of which the pump is a part. An accumulator between the pump outlet and a catheter leading away from the pump alleviates inertial and viscous effects from the catheter. The armature pole portion has a fluid-contacting section of material which is compatible with and corrosion resistant to the fluid, and can be a body of magnetic material within a titanium enclosure or a body of chrome-molybdenum-iron alloy. The check valve and inlet are so arranged that the pump displacement can be reduced without reducing bubble pumping capability.

    Abstract: A liquid gas engine includes at least one combustion chamber, in which a liquid gas/air mixture is introduced and ignited, the liquid gas engine having an injection device which injects liquid gas via an injection nozzle. The injection nozzle opens into the combustion chamber, so that the liquid gas is injected directly into the combustion chamber.The direct injection of the liquid gas achieves ideal combustion conditions, particularly since liquid gas evaporating in the combustion chamber induces cooling which is utilized particularly under a high load.The liquid gas engine is preferably provided with an injection device which is designed as an alternating piston pump and which works on the energy accumulation principle.
