Abstract: In order to prevent clogging of the nozzle and to ensure that the intermediate image carrier (8) is uniformly wetted with toner suspension across its entire width directly at the beginning of the printing operation, the nozzle comprises a front chamber (3) which extends across the entire width of the intermediate image carrier (8). Toner suspension enters said front chamber and subsequently reaches, via narrow bores (4), an open rear chamber (5) which is filled with suspension as far as an overflow edge (6). At the beginning of the operation, the suspension flows over the edge (6), across an inclined surface (7) in order to be applied to the intermediate image carrier (8) in a film of given thickness. The thickness of the suspension film is determined by a gap (10) which is formed by the nozzle and the intermediate image carrier (8). The nozzle has a flat shape, so that several nozzles can be arranged over one another.

Abstract: A pressure saturator for impregnating porous substrate materials with solids in solution, in which a reservoir contains the saturant solution and has a base member with a portion forming a depression therein. A mandrel is disposed within the depression in spaced relation to the surface of the depression. Preferably, the distance between the surface of the depression and the mandrel is three times the thickness of the substrate material. Heating elements are disposed in the base and heat the portion of the base member forming the depression, thereby heating the solution between the mandrel and the surface of the depression. The substrate is fed into the saturator from a supply roll and is passed through the space between the depression and the mandrel. The heated solution causes solids from the solution to replace the air in the interstices of the substrate in a near 100 percent weight-to-weight saturation.

Preferably, the actuating means is pneumatic. Preferably, the die means is characterized by ease of convertibility of differing sizes, shapes and styles of work pieces.

Abstract: An apparatus for the application of a sizing composition or the like to a traveling web under high speed conditions which involves passing the web into the nip formed between two counter-rotating rolls and supplying a sizing composition to the nip to thereby form a pond of sizing material on both sides of the traveling web. Additional amounts of sizing material are constantly being supplied to the ponds by means of a suitable applicator and nozzle arrangement, while the depth of the ponds is controlled continuously by the application of a reduced pressure to the existing ponds resulting in some of the sizing composition being drawn up into the applicator from where it is delivered to a reservoir for further circulation through the applicator.

Abstract: An apparatus to distribute discrete particles and, while distribution is occurring means to coat the particles, uniformly with a liquid. The apparatus provides feeding the particles to a rotating plate which rotates at a speed such as to distribute the particles and to cause them to move outwardly to the edge of the plate from which they fall and a liquid distributing means comprising an annular skirt coaxial with and below the plate, the skirt receiving liquid internally thereof and rotating at a speed sufficient to expell the liquid outwardly from its lower edge towards the particles falling from the plate thereby coating these articles.

Abstract: A method for color-painting on a chromium-plated surface of a metal object to be painted in a desired color, wherein the chromium-plated surface of the object is coated with a mixture of a transparent paint and a coloring matter in the presence or absence of a thinner, followed by baking of the paint coating at a temperature of approximately 180 degrees Centigrade.

Abstract: Device for effecting protective treatments on manufactures in concrete constituted of the combination in a single apparatus of a panel for the heating of the surface to be treated provided with means for establishing on the surface itself a constant flow of hot air with the possibility to regulate the temperature, and of an assembly being apt to impregnate with a catalyzed monomer the surface of the already heat-treated concrete and to polymerize with hot water the catalyzed monomer once it has been absorbed by the manufacture itself.

Abstract: A size press having at least one coating nip avoids splashing of the sizing or equivalent coating agent by leading the web to be treated through said nip. Coating supply apparatus supplies coating pools at the nip entrance between a coating roller and the web entering said nip. The coating supply apparatus includes filling pieces in the nip entrance, placed in the coating pool in operating position. The filing pieces consist of permeable, porous, or perforated material and extend along the entire width of the web. The filling pieces suppress the coating pools and prevent or, at least, essentially decrease, the splashing of the coating agent.

Abstract: Apparatus for coating selected portions of the troughs of a corrugated pipe within an adhesive includes a support disposed within the pipe with a reservoir containing the adhesive disposed on the support. A pump, including a spout, is utilized for supplying the adhesive from the reservoir to a trough of the pipe. A rotatable applicator is supported on the support and contacts the trough of the pipe. The applicator itself is sized so as to fit within the trough, and contacts the adhesive in the trough and spreads the adhesive in the trough upon rotation. A trough shield, supported by the support and disposed in the path of rotation of the applicator, is utilized to prevent the applicator from contacting selected portions of the trough. A locator head is also disposed on the support and provides a way for aligning the spout, the applicator, and the trough shield with the trough.

Abstract: A band marking apparatus for producing marking bands at spaced intervals along an insulated wire employs two ink jet dispensers located on opposite sides of the moving wire at longitudinally spaced stations. The dispensers are driven in an oscillatory manner by means of a tachometer engaged with the wire so that the marking bands are produced at uniform intervals regardless of the speed of movement of the wire past the dispensers. To insure proper registration of the band segments produced by the respective dispensers on opposite sides of the wire, an electronic controller for the dispensers includes an adjustable phase selector to regulate the phase relationship of the oscillating dispensers. The controller also includes other circuitry to maintain linear signal relationships and to center the oscillations of the respective dispensers on the wire.
