Abstract: A movable wall member is mounted in the intake runner of an internal combustion engine manifold and connected to an actuator plate in the manifold plenum which moves the wall member in a longitudinal direction to increase the effective runner length. A rigid link or end panel is pivotally connected to the other end of the wall member and to the associated runner wall so that longitudinal movement of the wall member results in simultaneous transverse movement thereby reducing the effective cross-sectional flow area of the runner passage. The movable wall members of multiple runner passages are connected to a common actuator plate in the manifold plenum which reduces the effective plenum volume upon displacement of the actuator plate.

Abstract: The present invention provides a truck frame-mounted tool box glide system that can carry a hinged-lid type tool box. The glide system can store the tool box out of the way beneath a truck flat bed. The system permits the tool box to be pulled laterally out from the side of the truck until the box lid is completely exposed so that the lid can be swung upward to fully expose the box interior. Such a system permits full utilization of the tool box interior, even for heavy objects that can be lifted vertically into and out of the box. The system may provide for dual tool box mountings, where one tool box is mounted to each side of the truck.

Abstract: A high pressure water/abrasive jet cutting nozzle has a pair of centering rings that act through body-mounted balls to position a nozzle element-holding collet. The interior surfaces of the centering rings are eccentric with respect to the longitudinal axis of the nozzle assembly so that rotation of a centering ring will cause the nozzle element collet to shift transversely. By rotating one or the other, or both, centering rings the axis of the nozzle element can be adjusted relative to the nozzle jet-forming element so as to align the nozzle element with the water jet.

Abstract: Sintered films of Cd.sub.1-x Zn.sub.x S (0.ltoreq.x<1) with high optical transmittance are provided. These films are produced by applying a paste composed of powdered CdS and CdCl.sub.2 or of a mixture of CdS, ZnS and CdCl.sub.2 onto an appropriate substrate such as borosilicate glass, under an inert gas atmosphere containing ZnCl.sub.2 vapor or thereafter resintering the paste on the substrate under a nitrogen atmosphere.The ZnCl.sub.2 vapor is produced by heating ZnCl.sub.2 at 400.degree. C. or higher but below the temperature of 500.degree.-700.degree. C. to which the specimen is heated.The resulting sintered films have optical transmittance of 80% at long wavelength ranges or higher and can be used as a window layer having a superior optical transmittance in solar cells.
