Abstract: The invention relates to a process, and the products thereof, for the nonslip finishing of surfaces of objects more especially packaging materials, by applying a hotmelt plastic. The hotmelt may be applied in the form of a microfine random-strand nonwoven, in which the filaments are essentially from 300 to 10 .mu.m and more especially from 150 to 30 .mu.m in diameter and are welded firmly together where they cross one another, or in the form of a foam, in which case the foamed hotmelt is applied to the surfaces by means of suitable applicators in the form of thin 1-5 mm strands separated by intervals of from 10 to 100 mm.

Abstract: A process of reinforcing a polyethylene coated blank in which a reinforcing stripe is applied to a polyethylene coated web along a longitudinal score line which is to be scored. The web is thereafter scored along the line and the blank is cut from the web. The reinforcing stripe has a major portion of polyethylene, a small amount of vinyl acetate and a polypropylene/polyisobutylene copolymer. During the application, the stripe material has a viscosity of 18,000-26,000 centipoise.

Abstract: Significant improvements in the coating characteristics of electrostatic fluidized beds are obtained by limiting the weight of the fines in the coating powder to certain maximum levels, e.g., no more than 10% by weight of minus 38 micrometer particles. The improvements include faster build rates, higher deposition weights, and deeper penetration into holes, slots or other cavities of the substrate.

Abstract: Apparatus for processing samples, such as tissue samples, including a rotatable table which carries either the samples or solutions in which the samples are to be immersed. The table is rotatable between a series of sample processing stations and is also arranged for axial movement between positions at which a sample is and is not respectively immersed in a solution. A single reversible motor is operable to both rotate the table and cause axial movement thereof. The motor drives a spindle having a double helix and also drives the table through a one way clutch arranged so that in one mode of operation the motor rotates both the spindle and the table and in another mode it rotates the spindle only. In the latter case the table is caused to move up and down the spindle as a result of cooperation between a follower and the helix tracks of the spindle.

Abstract: An apparatus for enveloping a battery plate with a microporous battery separator material by a dip method. The method involves first removing air bubbles from the plate by dipping the plate in a liquid, then dipping the plate into a polymer-solvent-filler suspension. After removal from the polymer-solvent-filler suspension, the plate is dried by evaporation or contacted with a nonsolvent and then dried. The result is the formation of a microporous separator envelope about the battery plate. The apparatus comprises a plurality of tanks for housing components for the production of the envelopes, into which tanks a battery plate can be sequentially dipped. Additionally, the apparatus includes a screen between the first two tanks for attracting liquid when contacted by a wet battery plate, a dryer, and a plate carrier.

Abstract: A method and apparatus for continually depositing coating materials on a moving web in precise shapes or patterns. Two enclosed chambers and a rotatably mounted mask having pattern-shaped openings formed therein are provided, with the mask openings being alternately movable between each of the enclosed chambers. In one enclosed chamber, coating materials are applied through the mask openings to web materials presented thereat. In the other chamber, cleaning apparatus continuously cleans rotary mask surfaces to thereby prevent pattern-definition-degrading coating material buildup on rotary mask surfaces immediately adjacent the mask openings. Apparatus is also provided for generating and maintaining a partial vacuum within each enclosed chamber.

The process includes the steps of providing a metallic substrate having a surface covered by a photo-resist coating, forming the photo-resist coating with a pattern of hard and soft portions, removing the photo-resist coating at the soft portions to expose surface portions of the metallic substrate beneath the soft portions of the photo-resist coating, etching the metallic substrate with the hard portion of the photo-resist coating retained thereon to form pits in the surface portions of the metallic substrate, spraying molten filler material on the surface of the metallic substrate with the hard portion of the photo-resist coating thereon, to fill the pits with the filler material of a porous structure having an oil-retaining capability, and removing the hard portion of the photo-resist coating from the metallic substrate.

Abstract: An apparatus for cleaning and spray painting pole structures. The apparatus includes a carriage constructed to be upwardly and downwardly movable along the axis of the pole to be cleaned or painted. Mounted on the carriage is a carousel rotatably secured so as to revolve around the pole as the carriage moves upwardly and downwardly. The carousel may be provided with brushes for cleaning the pole or with a paint sprayer for applying paint. In one embodiment two pairs of rollers are located symmetically with respect to the sprayer and the poles so that the rollers evenly apply the paint to the pole and simultaneously minimize overspray losses.

Abstract: A printing screen for screen printing fabrication substances such as solder paste has an aperture formed therein so that the screen may be placed on a substrate surface with a pre-mounted device extending through the aperture. A metal cap is bonded to the screen over the pre-mounted device to protect the device against damage during a subsequent screen printing operation. Different elements may, therefore, be bonded to a substrate in completely independent steps without the need for fluxing operations in later bonding operations.

Abstract: A deflecting device includes a deflecting electrode (13), which is disposed at a spacing below a lip nozzle (11.1), from which the viscous coating material (10.2, 10.1) flowing freely in the form of a sheet is emerging, and which extends over the entire width of the coating material sheet. This deflecting electrode includes an electrode arrangement (31), the exposure region of which facing the sheet surface is subdivided into a number of electrode elements (33) which taper outwardly to a point. When placed under a voltage, the electrode arrangement (31) provides an ion stream directed towards the surface of the coating material sheet. The impact of this ion stream on the surface of the coating material sheet (10.2) imparts to the latter a change in direction (.alpha.) towards the deflecting electrode (13), so that a flat substrate (5.1) running horizontally towards the deflected coating material sheet (10.1) impinges on the sheet (10.1) at an acute angle (.beta.). The impact of the substrate (5.

Abstract: A process and apparatus for manufacturing synthetic decorative coverings is presented in which at least one powder (generally a polymeric resin) is selectively deposited, in accordance with a pattern or decoration, onto a base material. The power deposition is carried out under gravity without contact between the means of applying the powder and the base. At least one of the deposited powders contains particles which are fusible at a temperature below the distortion temperature of the base and which is compatible with the base material. At least one thermal treatment is then carried out at a temperature below the distortion temperature of the base so as to fix the decorative pattern produced by deposited powders. The apparatus for applying the powders consists of a continuous screen printing frame, in particular, a screen printing roller which is fed by a device providing uniform distribution of the powder into a hopper located inside the roller.
