  • Patent number: 5626674
    Abstract: The method of treating the surfaces of malleable light metal cylinder bores or other objects by blasting the surfaces with extremely high water jets for preparing such surfaces for subsequent coating with wear-resistant materials such as a thermal spray coating. The water not only cleans the surface but roughens it to produce a pitted surface with undercuts so that coating material fills the pits and undercuts to provide a smooth layer of coating material with a strong mechanical/adhesive bond.

  • Patent number: 5339510
    Abstract: A method of manufacturing a wiper blade for a windshield wiper system of a motor vehicle is described, in which wiper blade a pivot pin, that is cylindrical all along its length, is non-rotatably fixed onto a secondary yoke and engages into bearing bushes by way of its ends, which bearing bushes are non-rotatably fixed into the side walls of a primary yoke. This articulated connection is advantageous with respect to corrosional behaviour and thus with respect to the lifetime in comparison to known articulated connections with an articulated rivet that is non-rotatably connected with the primary yoke.

  • Patent number: 5035042
    Abstract: An improved method of manufacturing galvanized steel tubing from steel strip having at least one galvanized surface, which surface becomes the exterior surface of the tubing is provided. In the method of the invention, after the steel strip is roll-formed and welded to complete the tubing and the welded seam is scarfed to remove irregularities, a quantity of an acid solution is applied to substantially only the scarfed area to react with oxidized metal, and then rinsed, leaving the non-scarfed galvanized exterior surface intact. The tubing is then heated to a temperature sufficient to cause the galvanized coating of the exterior surface to begin to flow and the tubing is regalvanized to produce an improved galvanized exterior surface, which is resistant to cracking along the scarfed area.

  • Patent number: 4982469
    Abstract: A sheet surface cleaing apparatus for cleaning the surface of a sheet on which painting or printing is to be conducted. The apparatus has a rotatable dust removing roll having a sticky surface capable of making rolling contact with the sheet surface to be cleaned. The apparatus also has a roll cleaning device mounted for movement parallel with the axis of rotation of the dust removing roll and capable of cleaning the surface of the dust removing roll. The dust removing roll is mounted for swinging movement between a position where it engages the roll cleaning device and a position where it engages the sheet surface. The surface of the roll cleaning device contactable with the dust removing roll is formed of a flexible porous cleaning pad which is mounted so as to be delivered in a direction perpendicular to the axis of rotation of the dust removing roll.

  • Patent number: 4962581
    Abstract: A blade sheath for the circular disk of a rotary slicer is a narrow strip of flexible, but abrasion resistant, material and includes a longitiudinal channel. The two sheath ends are joined by a clip and bail to form a continuous loop. When the blade is placed in the channel of the sheath and the bail and clip are in the locked position, the the cutting edge of the blade is completely covered and the the blade surface is exposed for cleaning.

  • Patent number: 4919157
    Abstract: Metal components for cathode ray tubes have up till now been degreased by washing with halogenated hydrocarbons. These degreasing agents pollute the environment, The new method is ecologically sound and the metal components are cleaned so thoroughly that they may be used for high vacuum applications. The metal components (12) to be cleaned are preferably heated in a reducing atmosphere at to C. for 5 to 45 minutes in a continuous furnace (1) which is formed integral with a blackening furnace (2).The method enables a simple, reproducible undangerous and ecologically sound cleaning. After burning the exhaust gases the emissions only consist of carbon dioxide and water.

  • Patent number: 4517024
    Abstract: Wire is passed through apparatus having two treatment zones, the first treatment zone containing six wire cleaning heads and the second treatment zone containing two wire cleaning heads. Each cleaning head consists of a primary cylindrical chamber flanked by two secondary cylindrical chambers of substantially smaller diameter, the wire passing axially through the cylinders. A working fluid such as dilute alkali, water or an organic solvent is pumped into the primary cylindrical chamber via a tangentially aligned inlet, it circulates in the primary chamber, and leaves via the secondary chamber with a very high annular velocity due to the reduction in the diameter of circulation. The high circulation speed causes vibration in and around the wire in the secondary chambers with resultant abrasion of the surface of the wire. In an alternative embodiment up to all but one of the cleaning heads may be replaced by dies.

  • Patent number: 4021910
    Abstract: A method for treating investment cast superalloy castings wherein the portions of the castings which solidify directly against the mold walls comprise a substantially continuous or encapsulating skin of a metallic and/or nonmetallic composition. In such castings, defects in the form of material voids, including defects present immediately beneath the skin, are eliminated by the application of heat and pressure. The castings are heated to temperatures sufficient to achieve metal movement in the form of yield or creep, and a pressure of at least about 10,000 psi is applied by means of a surrounding gaseous atmosphere. The heat and pressure application deforms the material in the area of the voids and consolidates this material to substantially remove the voids and to thereby improve the performance characteristics of the castings.
