A process for adjusting the boost pressure in an internal-combustion engine, supercharged by an exhaust-gas turbocharger with adjustable turbine diffuser, to a predetermined desired boost-pressure value dependent on the operating point. To improve the efficiency of the internal-combustion engine in the non-steady-state...
Hot gas engine units of the type having parallel cylinders in two parallel rows and containing pistons connected to two parallel crank shafts engaging a common third output shaft are juxtaposed into an assemblage of four such units. The output shaft is common to all four units and each of four crank shafts is connected...
A gas-insulated transmission line includes an outer sheath, an inner conductor, insulating supports and an insulating gas. A particle-trapping ring is secured to each insulating support, and it is comprised of a central portion and two tapered end portions. The ends of the particle trapping ring have a smaller diameter...
An engine case of a gas turbine engine is selectively coated with a thermal barrier coating to control axial clearance between rotating and stationary airfoils. The coating is applied to the thinner portions of the engine case to retard thermal expansion of these portions of the engine case during transient conditions ...
An insert retention gas tight seal for an electrical connector is disclosed. The insert retention, gas tight seal includes an annular groove defined by the interior surface of the connector housing within the receptacle and the plug, an annular ring of soft metal, and a tool to force the ring into the annular groove in...
An improvement in a grease box comprising a casing having a closed expandable hollow body, the hollow body containing an electrolytic fluid into which a galvanic element is advanceable to produce gas under pressure to effect expansion of the hollow body which, in turn, effects dispensation of a lubricant out of a chamb...
A catalyst for removing hydrocarbons from exhaust gas containing methane and an excess of oxygen, which comprises palladium or palladium/platinum supported on at least one carrier selected from zirconia, sulfated zirconia and tungsten-zirconia, and a method for treating exhaust gas using the catalyst....
A wet process for stack gas treatment wherein the stack gas is scrubbed with a suspension containing calcium hydroxide and/or calcium carbonate to remove sulfur oxides from the gas, characterized in that (1) air or oxygen-containing gas is supplied to the gas scrubber so as to oxidize at least 18% of the sulfur o...
