Abstract: Disclosed is a method and apparatus for providing surface replication in a coating on a sheet material. The method comprises the steps of:A. applying a flowable coating of a settable composition or material to one side of a web of sheet material;B. pressing the coated side of the sheet material against a replicative surface having a desired contoured surface effect of peaks and valleys to cause the surface of the coating to conform to the replicative surface;C. setting the coating to a nonflowable state at least sufficiently to enable it to be removed from the replicative surface securely attached to the sheet material and with the replicated surface effect in the coating being maintained; andD.

Abstract: A generally non-transparent substrate is rendered substantially transparent, for example at a particular location or locations thereon, by electrostatically depositing finely divided transparentizing particles onto the substrate and then heating those particles to facilitate their flow into the intersticies of the substrate. The transparentizing particles have an optical refractive index that is substantially the same as that of the substrate, and these transparentizing particles have a melting point greater than that encountered during handling and storage and less than the temperature at which the substrate would be damaged.

Abstract: This tool is used to produce specific patterns in wax on sporting equipment, such as surfboards, sailboards, skis, etc. Primarily, it consists of a hand-held body, having a multiple number of spaced pins or teeth secured to its bottom, which are used to produce the patterns which will provide greater traction for the equipment.

Abstract: A manually-operated applicator for use in applying a film of wet material in a preselected, uniform, initial wet film thickness on the top flat surface of a workpiece which is in a level position. The applicator comprises a cylindrical rod having a plurality of equally spaced-apart, annularly-shaped protrusions which form contact surfaces with the wet material and with the surface of the workpiece. The protrusions extend from the circumferential surface of the applicator a distance equal to the desired uniform thickness of the wet film. The wet material is manually rolled or pushed or pulled with the applicator by the user until the wet material covers the surface of the workpiece in its entirety, and until the top surface of the wet film is flush and level with the contacting circumferential surface of the applicator.

Abstract: The recording of surface topology is obtained by first bringing the surface into contact with the imaging material-coated side of a dry process dispersion type recording film comprising a transparent substrate on which is coated a very thin, high optical density, opaque body of imaging material, preferably coated with a thin abrasion-resistant protective layer. Radiant energy is then momentarily directed to the imaging material through the transparent substrate. When the heat generated by the absorbed radiant energy is above a given threshold value at a particular location of the imaging material, the material deforms and disperses thereat to form connected or unconnected globules with spaces therebetween. Upon termination of the radiant energy, the dispersed material becomes frozen in place.

Abstract: An apparatus and method for applying an adhesive to the edge of the can by inserting the can into the adhesive to its top surface and rotating the can 360.degree. or more, then past the edge of a doctor roll to remove excess adhesive in a selected region and then advancing the cans through an induction heater in a continuous motion until the can reaches a discharge station where it is released.

Abstract: In gas stripping excess coating material (such as molten zinc) from rising sheet material (such as continuous steel strip) uneven coating adjacent the strip edges is deterred by a baffle plate having a vertical portion held close to but not touching the strip and disposed normally to the strip edge, and a remainder portion trended away from that edge. The baffle plate is fixed on one end of a carrier plate suspended on a truck spring urged towards the sheet. The carrier plate extends further from the strip edge than does said remainder portion and the horizontal length of the carrier plate is from 10 to 20 times the width of said vertical portion.

Abstract: An apparatus is disclosed for continuous distribution of a latex or urethane foam composition on a movable substrate to produce a foamed sheet material such as a foam backed carpet. The distribution apparatus comprises a generally cylindrically shaped rotatable member and at least two attached distribution means which may take the form of either modified doctor rolls or modified doctor blades. The distribution surface of each of these distribution means may differ and may be either smooth or patterned with a variety of grooves or serrations thereby providing means for producing foamed sheet materials with surfaces which are either planar or patterned with ridges and valleys. Means are also provided to readily change the thickness of the distributed foam and for oscillating the distribution apparatus to produce a surface with wavy as opposed to linear patterns of ridges and valleys. All of these operations may be accomplished without interrupting the continuous process.

Abstract: Apparatus for the quantity production of friction nuts prepared for subsequent fusion of thermoplastic resin particles deposited in thread grooves therein, in which the nuts are supported with their axes vertical, a fluid slurry of the particles in a liquid carrier is introduced into the threaded interior of the nuts to fill the threaded opening, including the thread grooves therein, either completely or to a predetermined level from the bottom of the nuts. Excess slurry is then drained from the bottom ends of the openings. The exterior of the nuts is washed or otherwise cleared of any slurry thereon. In order to leave the threads clear of obstruction at the bottom of the nut, the deposited slurry, after partially drying, is removed from the bottom thread convolutions by repeatedly inserting and withdrawing a sponge-like material directly into and out of the lower end of the thread opening, or by strongly agitating a small quantity of water in the lower part of the threaded opening, or otherwise.

Abstract: A reactive polyurethane mixture is applied by a high pressure airless spray applicator directly onto the primary backing of a moving substrate such as a carpet web. The applied reactive mixture is allowed to foam to an approximate predetermined thickness and density. While the blown or foamed backing layer still possesses substantial residual tackiness, it is compressed or regauged to a precise uniform thickness and simultaneously is provided with either an embossed or a smooth surface. The tack of internal cell walls of the blown backing layer retains the layer at the regauged thickness. Curing of the regauged backing layer by externally applied heat and/or by the heat of the exothermic reaction in the applied mixture is completed. Detackifying agents are applied to the regauging devices and/or to the applied backing layer to prevent adherence of the layer to the regauging devices. A surface skin formed of the detackifying agents is cured on the regauged backing layer.

Abstract: A metalized plastic foil is demetalized along an edge by means of a rotating, narrow steel disk whose periphery has been roughened by means of sandblasting or electroerosion.

Abstract: An apparatus and method for applying a uniform coating of liquid solder to a flat tube particularly at and adjacent to the side edges of the tube. The apparatus has spaced heated platens comprising shaping die members located opposite to each other and including tube embracing recesses forming a slot through which the liquid solder coated tube is passed. The disclosure also includes spacing means for spacing these die members apart a distance equal to the width of the coated tubes and yieldable means such as springs urging the spaced heated platens toward each other to bear against the side edges of the tube together with means for drawing the coated tube between the heated platens and means for heating the platens in the vicinity of the tube to a temperature above the melting point of the solder as well as passages permitting draining of excess solder from the tube during its passage between the heated platens.

Abstract: To obtain optical effects, particularly dye pattern effects, a treatment is proposed for a web of material or a number of webs of material guided side by side in the nip between treatment rollers, more particularly a web of material impregnated with or containing dye or other finishes, wherein the treatment pressure is set differently in individual longitudinal portions of the nip or is set intermittently, so that the web of material is exposed to different treatment pressures at different points, with the result that, in particular, the dye or other finish is forced out of the parts of the web of material subjected to the greatest pressure, and into those parts subjected to least pressure. An apparatus is proposed for carrying out this treatment, wherein one of the treatment rollers which form the nip is a deflection adjustment roller and comprises support members which are associated with controllable pressure regulators for regulating the pressure in the support members.
