摘要:
An electrochromic device useful as a smart window comprises a pair of transparent doped tin oxide layers that serve as the terminal electrodes, and between which are sandwiched an electrochemical cell including a layer of electrochromic material and between the layer of electrochromic material and its proximate termial is inserted a layer of tin oxide whose normal resistance is large compared to the lateral resistance of the proximate doped tin oxide layer. This serves to improve the lateral uniformity of the potential applied to the electrochemical cell when a voltage is applied across the terminal electrodes with a resultant improvement in the uniformity of coloring and bleaching across the surface of the electrochromic layer.

A resilient mount is disclosed comprising a spring element retained between two mount retaining means and a controllable magnet fastened to one of the two mount retaining means. The magnet is adapted to cooperate with a magnetically responsive element to vary the spring characteristic of the resilient mount on a continuous basis with the magnetically responsive element fixed inside the spring element.

Method and apparatus for assembling a spline-type connection wherein a plurality of angularly spaced spline teeth on a first member project radially from a circular edge thereof and are disposed in an imaginary annulus concentric with the circular edge, a staging annulus corresponding in size to the imaginary annulus is formed on a second member at one end of and perpendicular to a cylindrical wall on the second member adapted to slidably receive the circular edge of the first member, a frusto-conical centering guide shoulder is formed on the second member around the staging annulus and extends longitudinally outboard from the staging annulus, and a plurality of spline grooves are formed in the cylindrical wall and intersect the staging annulus at a corresponding plurality of notches angularly spaced to register with the spline teeth. During assembly, the first member is advanced to a staged position on the second member wherein the spline teeth rest on the staging annulus and is then rotated in the staged position to register the spline teeth with the notches to permit advancement of the spline teeth along the spline grooves.

An engine, preferably of the heavy duty diesel internal combustion type, is provided with a crankcase having downwardly extending side walls interconnected by a stiffening bridge member. The bridge member includes integral mounting means for an oil pump and its drive shaft and supports a drive gear that directly engages a driving gear on the engine crankshaft immediately above the assembly.

In a motor vehicle having a body with a horizontal frame part forming part of a lower mounting for the base of a radiator and two spaced vertical frame parts forming parts of two lateral mountings for the radiator, the radiator is mounted at its base by means of a pin fixed on the base of the radiator and engaging in a rubber block fixed on the horizontal frame part, the two side portions of the radiator carrying hollow cylindrical blocks which are engaged by the spigot ends of plugs which are inserted through corresponding openings in the vertical frame parts from the outboard sides thereof and are clamped to the vertical frame parts by formations providing a bayonet type connection.
摘要:
An indexing mechanism that converts reciprocal movement into rotary movement and that includes a driver member supported for movement along a straight line between a first position and a second position. A driven member in the form of a sleeve encircles the driver member and has a series of circumferentially spaced identical helical grooves formed in the inner surface thereof. Each pair of adjacent helical grooves have a straight tapered groove connecting one end of one helical groove to the other end of the other helical groove. A driver cam is normally located in one of the helical grooves and is resiliently supported on the driver member which, in turn, is connected to a linear actuator that serves to move the driver member from the first position to the second position so as to cause the cam member to move within the helical groove and rotate the driven member a predetermined distance.
摘要:
Arrangements for internal combustion engine exhaust manifold converter-reactors for controlling hydrocarbon, carbon monoxide and nitrogen oxide emissions. The arrangements involve concentric primary and secondary oxidizing zones separated by a tubular element forming a reduction catalyst. A swirl flow is created by tangential entry of inlet ports to the primary oxidizing zones to maximize residence times in the various zones.
摘要:
A combustion apparatus for gas turbine engines particularly adapted to reduce emissions to meet automotive requirements. The fuel is laid on the wall of a cylindrical prechamber and evaporated from the wall by combustion air which is introduced through a swirler at the upstream end of the prechamber. The inner surface of the prechamber is artificially roughened by a grid of grooves to improve fuel evaporation. The fuel is laid on the wall from an annular manifold extending around the upstream end of the prechamber through tangential orifices leading from the manifold into the interior of the prechamber. The fuel manifold is cooled and shielded from heat by an air jacket. More air enters through entrance ports distributed around the prechamber toward its downstream end. The resulting lean fuel-air mixture is delivered past an annular flow dam at the outlet of the prechamber into a combustion or reaction zone which is abruptly enlarged from the prechamber. The structure causes turbulent flow, recirculation, and good mixing in the reaction zone. A dilution zone downstream of the reaction zone has a circumferential array of dilution air ports which are of such shape as to be varied nonlinearly in area by a sliding ring valve. The sliding ring valve is coupled to a second sliding ring valve which varies the area of the air entrance ports in the prechamber in reverse sense to the dilution air ports. A pilot fuel nozzle to aid in cold starts is mounted at the upstream end of the prechamber.
