Abstract: A restoration process for restoring surface porosity defects in engine blocks cast using a high pressure die cast method. The areas of an engine block having surface porosity defects are identified and the areas not containing surface porosity defects are masked using an adhesive, reusable, rubberized mask. The masked surface is subsequently cleaned and a metal spray is applied to the surface porosity defects. The mask is removed and the restored surface porosity defects are hand finished to create an engine block having less than 0.05% surface porosity.

Abstract: A heat sink vacuum packaging procedure to rapidly complete the packaging of a heat sink without drilling, pipe welding, vacuum pumping, or other processes. Because the packaging procedure saves much time and labor, the manufacturing cost of the heat sink is relatively reduced. During packaging, no welding process is employed, therefore the invention prevents accidentally flowing of tin solder into the inside of the heat sink to affect the quality of the heat sink, and the quality of the heat sink is maintained.

Abstract: An apparatus and method for folding a hinged molded part in a molding machine. As a part-removal apparatus, preferably a swing arm mechanism, grips one of the lid portion or the base portion of the molded part and moves the molded part out of the mold, a deflector connected to a portion of the mold engages the other portion of the part and initiates folding of the lid portion to the base portion at the hinge. The deflector further folds the part as the mold closes. The portions of the part are pushed together and latched in one embodiment by the swing arm mechanism that grips and moves the molded part against the deflector, and in another embodiment by a closing actuator operated separately from the swing arm mechanism.

The system includes a U-shaped installation tool whose arms releasably engage fastening elements (hooks or links) at one end of each side chain, and a installation tray or ramp in which the connected tire chain and tool are arranged, and may be stored, prior to installation, with the tire chain in a partially laid-out orientation and the tool preferably within a tool compartment in the tray. To install the tire chain, the vehicle is driven onto the tray and stopped, preferably in a predetermined optimum position in response to a signal initiated by a position-indicating switch on the tray. Then the tool, with one end of the tire chain connected to it and trailing it, is drawn upward and circumferentially around the tire.

Abstract: There are disclosed a method and apparatus for applying a strippable paint to a large-sized product finished with a sprayed coating, such as an automobile, to form a protective film on the surface of the coating. The product is conventionally kept in stock for a period of time before it is shipped. Contaminations such as dust are washed away from the surface of the product. Then, the strippable paint is applied, preliminarily dried, and non-preliminarily dried to form the protective film out of the strippable paint on the surface of the coating. This protective film is formed easily, appropriately, and reliably. The obtained protective film has a uniform and sufficient thickness. Even if the surface contains unapplied regions to which the paint should not be applied, the paint can be applied to the whole surface of the coating while avoiding the unapplied regions according to the invention. The application can be performed easily and reliably without leaving unapplied portions around the unapplied regions.

Abstract: A cylinder housing (1) is cast with a cylinder wall (2) in the making of a cylinder for an internal combustion engine. The cylinder wall delimits an interior space (3) for accommodating a reciprocating piston and, thereafter, a control window (5) is machined into the cylinder wall (2) as an opening of a transfer channel (4) into the interior space (3). A two-stage machining for forming the control window (5) is provided in order to make possible a rapid and cost effective manufacture of the cylinder. In a first step with a work tool (7) having a rotating primary movement (11), a breakthrough (10) is machined into the cylinder wall (2) and, in a second step with a work tool, the breakthrough (10) is widened to the wanted dimensions of the control window (5).

Abstract: The method includes the steps of determining a number of gear teeth for each gear and pinion that, in combination, would produce desired gear ratios. Current gearset parameters including distances and angles relating the positions of the gears and pinions are determined. For a predetermined angular rotation of a selected gear or pinion, and using the current gearset parameters, an error is determined representing a difference in phases of a tooth on the selected gear or pinion into its mesh cycle. A first phase is determined along a first portion of a drive path of meshing gears and pinions, and a second phase is determined along a second portion of the drive path distinct from the first portion. One or more of the current gearset parameters are repetitively changed to determine a set of correspond optimal gearset parameters, for which the error is equal to or less than an acceptable error. Then a gearset having the optimal gearset parameters is produced.
