Abstract: Extremely small, three-dimensional articles, such as fusion targets having glass shells (20 to 500 microns in diameter) are coated with alternate layers of colloidal materials. This is accomplished by depositing particles of opposite charge from colloidal suspensions (sols). Articles to be coated are suspended within a drop held in the open end of a closed capillary tube, and colloidal particles are deposited by dipping the capillary into the sols. Alternate monolayers of the particles adhere to the surface of the article. Multilayer coatings are built up by repeated alternate deposition of the monolayers from the sols. Between each deposition, the layers are rinsed with water and the water removed by dipping the capillary tube into a bath of water and then into a bath containing a water displacing agent such as ethanol or dimethyl sulfoxide.

Abstract: A stud arrangement on casehardened studded chains for motor vehicles, wherein the studs consist of a steel body which is permanently welded to a chain link and provided with a centrally disposed hard metal pin. The hard metal pin is inserted into the steel body such that it is covered on all sides by steel material of a thickness which at least corresponds to the casehardening penetration depth. In a method for producing such studded chains, an inwardly converging blind hole is cut out from one end of the steel body. The hard metal pin, of a shape corresponding to the conical hole, is forced into the hole, the pin being shorter than the blind hole so that a skirt is formed outside the pin. The edge of the skirt is beveled, and the steel body with the metal pin therein is joined to the chain by resistance welding in a machine for welding studs onto chain links, the body with the pin being moved gradually toward the chain link as the beveled edge melts and flows radially outwards.

Abstract: A reflective heat transfer combination and the method of making same whereby a tacky mixture of tack wax and mineral spirits defines a carrier layer applied over a paper substrate capable of absorbing the carrier layer when melted in response to heat and disposing a layer of glass beads over the carrier layer and forcing the glass beads into the carrier layer and against the paper substrate while allowing portions of the beads to be exposed above the carrier layer. A liquid binder layer of acrylic plastic is disposed around the beads and over the carrier layer while leaving portions of the beads exposed and is dried to retain the beads in position. Thereafter a liquid reflective coat of acrylic plastic is applied over the binder layer and covering the beads to provide a reflective background for reflecting light back through the beads. While the reflective coat is liquid and before being dried, a powdered adhesive is disposed over the reflective coat and thereafter the reflective coat is dried.

Abstract: A ceramic transfer picture with a water-absorbing separable paper carrier is provided with a screening layer on its surface opposite the image layer. Said screening layer leaves uncovered only the image areas to be moistened; further, a compensating layer of polyglycol or polyethylglycol wax is provided at or in the image layer as well as an organic intermediate layer between the paper carrier and the image layer controlling the plasiticization of the image layer. In order to achieve a fast separation of the images from the paper carrier, steam is raised during the transfer of the decalcamia pictures. Owing to the nonabsorbent screening layer, the paper carrier is strong so that material in rolls may be used in a mechanical transfer.

Abstract: Copy sheets having a re-fusable xerographic toner along an edge thereof are bound into booklets by arranging the sheets in a stack and re-fusing the toner so that the re-fused toner adheres adjacent sheets together. The re-fusing operation can be accomplished after each group of a few sheets is received from a copier so that the finisher operation can be carried on at the same rate copies are produced by the copier. Alternately, a larger stack of sheets can be bound together in an off-line basis by a simple heating step.

Abstract: A continuous strip of puncture sealing material is applied to an inside surface of a tire by laying and adhering a plurality of side-by-side turns of the strip with the different turns connected by angular crossing portions in the area of a first circumferential position of the tire. The first crossing portion overlaps a first end of the first turn. The other end of the strip is tapered and overlaps the last crossing portion and a portion of the last turn of the strip. The first circumferential position of the tire may be at a light spot circumferentially of the tire for improved balance of the tire. By overlapping the edge of the strip and pressing the material against the tire surface, the resulting puncture sealing layer is continuous and completely covers the surface of the tire under the crown portion for protection against punctures due to nails and other sharp objects.

Abstract: A spliced web and method for splicing web end portions together for minimizing splice-induced disturbance of a liquid composition continuously coated onto the face side of the spliced web during a coating operation. Splicing strips are applied overlying the face and opposite sides of the web end portions to form a sandwich, and the sandwich is subjected to heat and pressure. The splicing strip on the face side fuses with and impregnates the web end portions and forms slight trailing and leading ramp surfaces of gradually decreasing thickness which blend smoothly with the face side of the web for minimizing coating disturbances. The other splicing strip contains fibers which are embedded into or adhere to the opposite side of the web end portions to provide tensile strength to the spliced web.
