  • Patent number: 6855208
    Abstract: This invention relates to a metal part and other surface modification method suitable for the machining industry in which shot peening is typically used to refine the surface of a metal part (to introduce compressive residual stresses, to enhance fatigue strength, to harden the workpiece) and for fields in which parts need be cleaned. According to the present invention, workpiece W is placed within a first vessel which is filled with a fluid. The first vessel is pressurized by controlling the flow rate of the fluid flowing in the first vessel from nozzle 4 distant from said workpiece on the surface and of the fluid flowing from first vessel. Thus, the collapsing impact force of cavitation bubbles is increased so that the machined part will have its surface strengthened and cleaned by applying a peening effect to the surface of the part with said impact force.

    Abstract: Deicing of an external mirror (10) on a vehicle is effected by applying a sudden deformation force to the mirror. Sandwiched between the mirror (10) and a mounting surface (12) is a structure that includes a ribbon conductor (14), portions of which overlap each other in such a way that current through the conductor passes through these portions in opposite directions. A capacitor (32) is discharged through the conductor (14), generating a magnetic field that results in mutual repulsion between the overlapping portions. The mounting surface resists this repulsion force, which is instead transferred to the mirror (10), causing momentary distortion, and dislodgment of ice on the mirror surface. The same technique is also applicable to deicing of windows.

    Abstract: A cleaning device for a paint brush comprises a hollow nozzle attached to a source of pressurized cleaning solution such as water, solvent, liquefied hot soap or alike. The distal tip of the nozzle is equipped with a poppet valve such that the body of the valve protrudes from the distal tip. The proximal section of the nozzle is adapted to be attached to a source of cleaning solution, that in the most basic configuration being a common tap water valve. When the water valve is opened, the brush is moved towards the nozzle. Upon engaging with the heel or bristles of the brush, the poppet valve moves inwards and opens the flow of water towards the center of the brush allowing washing out any remaining wet and dissolved paint. In another embodiment of the invention, the cleaning device includes a hollow handle attached to a source of pressurized cleaning solution and equipped with one or more nozzles each having a poppet valve.

    Abstract: A pathological waste disposal unit (10) has a chamber (11) with a closeable cover (16) and a waste outlet (14) connected to a waste sump (20). A carrier (30) for waste bags (40) is mounted on a shaft (31), rotatable by an impellor (30), on which is directed high pressure water from nozzles (150). Water knives (70) cut open the waste bags (40) while the carrier (30) is rotating to release the waste (41) from the waste bags (40), to cause the waste to face the bottom wall (13) of the chamber (11) and flow through the waste outlet (14) to the waste sump (20). Safety interlock means prevent operation of the unit (10) while the cover (16) is raised and the opening of the cover (16) while the unit (10) is in operation.

  • Patent number: 6680097
    Abstract: A self-adhesive film label, in particular for reusable bottles, is proposed which can be readily detached in conventional washing equipment. This is achieved by means of a self-adhesive label with a stretched film layer, which shrinks back at elevated temperature in the washing device. Since the adhesive of the label loses its adhesive force at this temperature, the label is rapidly and readily detached, supported by the surrounding washing liquid of the washing device.

  • Patent number: 6660100
    Abstract: In a process for removing the paint from plastic components provided with coats of paint, the plastic components are first crushed to a bulk material size of the crushed plastic pieces. The plastic pieces are subsequently mixed with a paint removing agent reducing the adhesion of the coats of paint to the plastic pieces, and circulated by means of a conveyor screw. The paint removing agent is formed in this connection by an emulsion consisting of at least one benzyl-substituted alkanol and an alkyl-glycol acetate or N-alkyl-pyrrolidone with an aqueous lye, which can not be completely mixed. The mixing ratio for mixing the individual components is selected so that it is in the range of a mixing gap. After the paint removing agent has acted upon the painted plastic pieces, a solid substance is added to the paint remover so that the further steps of the method can be carried out in a dry state.

  • Patent number: 6651679
    Abstract: Process for the disintegration and cleaning of contaminant-containing raw paper stocks. The process includes producing a contaminant-containing suspension, feeding the contaminant-containing suspension to a closed coarse screen, drawing of a cleaned flow fraction from the closed coarse screen, and drawing off an overflow fraction containing an increased amount of contaminants from the coarse screen during at least about 80% of an operating time. The process also includes adjusting a volumetric mass flow of the overflow fraction to at least about 15% and maximally about 50% of a volumetric mass flow of an inflow into the coarse screen, and feeding the overflow fraction to a screening device, in which contaminants collected are sluiced out discontinuously as a further overflow fraction, thereby forming a further cleaned flow fraction.

  • Publication number: 20030213499
    Abstract: Deicing of an external mirror (10) on a vehicle is effected by applying a sudden deformation force to the mirror. Sandwiched between the mirror (10) and a mounting surface (12) is a structure that includes a ribbon conductor (14), portions of which overlap each other in such a way that current through the conductor passes through these portions in opposite directions. A capacitor (32) is discharged through the conductor (14), generating a magnetic field that results in mutual repulsion between the overlapping portions. The mounting surface resists this repulsion force, which is instead transferred to the mirror (10), causing momentary distortion, and dislodgment of ice on the mirror surface. The same technique is also applicable to deicing of windows.

    Abstract: Toner xerographically adhered to a material, such as a sheet of paper, may be removed using a solvent-based or solventless approach. The application of ultrasonic tamping, scraping and brushing may aid in removing toner particles. In a solvent-based approach, a solvent may be applied generally or the solvent may be targeted specifically to the toner covered portions of the material to loosen the adhesive securement of the toner to the material. Thereafter, the toner is subjected to a mechanical abrasion using ultrasonic and physical agitation to cause flaking of the toner.

    Abstract: A cleaning/polishing pad has a first surface with raised, substantially nubs, having a length greater than a width, arranged adjacent each other forming laterally alternating rows of nubs and having troughs interspersed therebetween, a second surface opposite the first surface, and a thickness. The troughs, which may contain polishing/cleaning chemicals, are divided into first and second groups of substantially parallel troughs. The groups of troughs are arranged at an angle to one another forming a hatch pattern. The pad can be formed to make roller brushes, circular brushes or manual wipes. For the circular brushes the nubs are arranged adjacent each other forming laterally alternating concentric circles of nubs. Micropores are interspersed within the pad having a gradient of pores with smaller pores towards the first surface and larger pores towards the second. There are no sharp edges or corners in/on the pad.

  • Patent number: 6632289
    Abstract: A to-be-cleaned substrate is cleaned by use of an acid liquid agent in a cleaning cup, the remaining acid liquid agent is washed out by use of pure water, then an alkaline liquid agent is emitted to the surface of the to-be-cleaned substrate in the same cleaning cup to remove the acid liquid agent remaining on the to-be-cleaned substrate. A neutralization reaction between the acid and alkali is caused by emitting the alkaline liquid agent to the surface of the to-be-cleaned substrate so as to efficiently remove the acid liquid agent remaining on the surface of the to-be-cleaned substrate.
