Abstract: A fabric conditioner composition is distributed on an air permeable sheet in such manner that the conditioner occludes interior interstitial spaces in certain region of the sheet to block airflow therethrough, and other regions of the sheet have interstitially open spaces, there being additional interstitial spaces in those other regions which are relatively smaller and which contain remanent conditioner.

Abstract: A powder applicator for applying powder to form a side stripe to the interior of can bodies along side seams thereof. The powder applicator includes a device for providing a layering effect on the gas entrained powder so that although the powder is normally carried by the gaseous stream it is directed into an orifice of a nozzle as a dense stream with the carrier gas forming a separate layer. In addition, the applicator forms a seal with the interior of the can body to define a limited sealed area within which the powder may pass. This sealed area contains corona charging pins which are arranged in a longitudinal line so that a maximum charging of the powder may be effected. Also, a diffused gas is directed into the sealed area to prevent the powder from clinging to the side walls of the sealed area and the charging pins.

Abstract: A device and method for applying mastic material to the weld bead area of longitudinally welded pipe is the subject of this application. An extruder is mounted on a framework and receives mastic material in rope form from a bulk spool positioned above the extruder.

Abstract: A decorative multicolored candle is produced by applying, to the side surface of a candle core, a removable solid member having a melting temperature higher than that of candle wax. The surface of the core and side member are coated successively with a plurality of superimposed different colored coatings of candle wax, and the solid member is removed through a slit cut in the superimposed coatings, thereby forming projections having multicolored free ends. Thereafter, one of more additional different colored coatings of candle wax are applied over the thus treated core. A sufficient amount of the additional coatings are then removed to expose the multicolored free ends of the projections outlined by the exposed colors of the additional coatings.

Abstract: An improved method of making hard and semi-rigid book covers, and the product obtained, provides a multi-layer plastic book with any desired ratio of flexibility to stiffness in the different parts of the cover such as the front and back panels, the hinge lines and the backbone panel that connects the front and back panels. A first layer of plastic is cast or extruded on a casting paper or belt or other supporting surface, and additional plastic material is applied to the first layer over areas that will form the front and back panels, and to the backbone area if the desired cover is one that is to have a stiffened backbone panel. A second layer is applied under conditions that insure a highly effective bonding and freedom from distortion when a curing step is necessary. The operation is continuous and the laminate formed is severed into separate covers as it is delivered from the laminating operation.

Stop members hold the application head a fixed distance from the localized region and a doctoring edge of the application head helps form a uniform layer or coating of the organic polymeric material completely encircling the localized region.

Abstract: A method is disclosed for applying rather viscous line marking material to road surfaces whereby simultaneously with the manufacturing of marking strips in the same continuous motion crossribs from the same material are shaped on the marking strips. The marking material flows out through a slit between the back edge of the bottom side and the lower edge of the back wall of a storage box, a periodical up- and down movement being imparted to this back wall for shaping the ribs, preferably by means of fast upward driving impulses each of one followed up by a separate downward driving impulse. Preferably the material is forced to flow out substantially in a direction at an angle of at least 30.degree. to the direction of movement of the storage box and the trailing end thereof is kept in engagement with the road surface.
