Abstract: A tool for manufacturing a multi-colored plastic automotive part, such as a door panel, is manufactured using multiple molding shots without opening the mold between each shot. The door panel comes out finished with no scuffing, warping, or shrinkage. The process for manufacturing the panel includes selectively locating spacers within the tool to a first position and then injecting a first material. The parting line is held closed while the spacers are then advanced to a second position so as to set the inner insert to a desired second shot wall thickness position. A second shot of material is then introduced into the rear of the injection unit through an opening in the first shot part. The process can be repeated for additional colors and materials to create a multi-colored or even multi-material final assembly. Once the part is cured, it is ejected and the process is complete.

Abstract: The image scanning system (52) of the present invention scans slides and film strips containing photographic images and creates a corresponding plurality of digital representations of the photographic images. The system (52) includes a touch screen monitor (96), a computer (54), a scanner (62), a high speed interface (112) and a printer (98). The scanner (62) includes a light source (172) for projecting light through the film strip. A light sensor (124) senses the light projected through the film strip and generates pixel data. A film drive advances the film strip between the light source (172) and the light sensor (124). A lens located between the light source and the light sensor directs the light projected through the film strip onto the light sensor (124). The pixel data is transmitted through the high speed interface (112) to the computer (54) for processing operations. After the pixel data has been processed, digital images are displayed on the monitor (96) and may also be printed out.

Abstract: A piston-type internal-combustion engine having at least one gas intake port (4) per cylinder, with the port discharging into the cylinder via at least one throughgoing opening (3). The port is subdivided, over at least a portion of its length, into at least two partial ports (4.1, 4.2) by at least one partitioning wall (5). The wall has a profile with a central separating portion on at least one surface being raised relative to the remaining portions of the at least one surface, to divide a flow within an associated partial port (4.1, 4.2) into two partial flow parts, which extend in the flow direction.

Abstract: A photographic film scanner for scanning a film strip containing a plurality of photographic images is disclosed. The film strip is advanced through the scanner and a digital image of the film strip is created. Individual images contained in the digital image of the film strip are located and displayed. The film strip is scanned at any of a variety of resolutions.

Abstract: An internal-combustion engine includes a cylinder, a piston reciprocating therein, intake and exhaust ports, a fuel injection nozzle opening into the combustion chamber of the cylinder and an ignition device situated in the top wall of the cylinder. The top wall of the cylinder as well as the piston base oriented towards the top wall each has first and second surfaces being inclined to one another and meeting in a ridge, whereby the top wall and the piston base have an essentially V-shaped configuration when viewed in a sectional plane taken along the cylinder axis. The first surface of the top wall faces and is parallel with the first surface of the piston base and the second surface of the top wall faces and is parallel with the second surface of the piston base. A dished depression is provided in the piston base such that the depression interrupts the ridge and extends on either side thereof, whereby the dished depression is bounded by the first and second surfaces of the piston base.

Abstract: The method of making refractory ceramic products in which a slurry is formed of water, powdered alumina, and amorphous fibers containing AL.sub.2 O.sub.3 and SiO.sub.2, the volume of water in the slurry being sufficient to permit the slurry to flow under vibration but insufficient to permit the slurry to flow without vibration, the fibers having a molecular ratio of Al.sub.2 O.sub.3 to SiO.sub.2 substantially less than 3 to 2 and the molecular ratio of Al.sub.2 O.sub.3 to SiO.sub.2 in the combined slurry being at least 3 to 2, thereater placing the slurry in a liquid absorbing mold and vibrating the slurry to fill the mold, then permitting the mold to absorb a portion of the water from the slurry to form a body, then removing the body from the mold and drying the body, and thereafter heating the body to combine silica and alumina from the fibers and powdered alumina to recrystalize the fibers in the from of mullite.

Abstract: The method of molding a ceramic product by forming a mixture of ceramic fibers with lengths less than one-fourth inch, water and a deflouculent, the mixture having a consistency which will not flow, placing the mixture in a water-absorbing mold, vibrating the mold to cause the mixture to flow into contact with the mold and eliminate voids in the mixture, allowing a portion of the water of the mixture to be absorbed by the mold leaving a hardened remnant in the mold, removing the hardened remnant from the mold, and heating the hardened remnant to sinter the fibers therein to each other. In one example, granular alumina is mixed with the mass of fibers, water and the deflouculent to form the mixture.

Abstract: Thermal expansion from the heating up of a pressure vessel in the form of elongated cylinder for containing a nuclear reaction is used to produce motion, beginning at a certain limit temperature, which is used to actuate a lever mechanism to open a safety valve which serves also for relief against overpressure. The thermal expansion of the pressure vessel itself may be used as the actuating force or an elongated rod-in-tube differential expansion device located between the pressure vessel and a nearby adjacent wall may be used to actuate the lever mechanism.
