Abstract: A brush for a machine for the horizontal and/or vertical cleaning of surfaces which are provided with grooves, joints, unevennesses and/or pores is provided to move the brush in a plane which is substantially parallel to a surface. This brush is provided with at least one set of first hairs for cleaning or polishing the parts of the surface which extend between the grooves, joints, unevennesses and/or pores, and at least one set of second hairs for cleaning the grooves, joints, unevennesses and/or pores. The brush includes a base plate which is releasably attached to one or several brush parts, which are provided with one or several sets of second hairs. A machine for the horizontal and/or vertical cleaning of surfaces which are provided with grooves, joints, unevennesses and/or pores is provided with one or several of such brushes.

Abstract: a brush for removing chewing gum remains and weeds from a surface (12), consists of a baseplate (4) provided with first hairs (1) and one or more detachable brush parts (5) provided with second hairs (2), in which the second hairs (2) extend beyond the first hairs (1) at the cleaning surface (11), and in which one or more first (1) or second hairs (2) are steel strips or wires having a serrated or toothed edge and/or tip. A machine for removing chewing gum remains has at least one such brush and is provided with a heating chamber (13) for heating chewing gum remains before the brush (10) moves across the surface. A method for removing chewing gum uses such a brush (10) or such a machine.

Abstract: The invention relates, on the one hand, to a brush (1) for a scrubbing, sweeping and/or polishing machine for mechanical cleaning of several surfaces that are separated from each other by means of grooves and/or joints, such as, inter alia, paving stones, tiles, Bangkirai and/or building bricks, wherein the scrubbing, sweeping and/or polishing machine is provided so as to move the brush in a plane that is substantially parallel to the said surfaces that are separated from each other, and a scrubbing, sweeping and/or polishing machine provided with one or more brushes (1), the brush (1) being provided with at least one set of polishing bristles (2) for cleaning or polishing the surfaces; at least one set of joint bristles (3) for cleaning the grooves and/or joints between the surfaces; and the polishing bristles (2) having a length that is shorter than the length of the joint bristles (3).

Abstract: Novel optical disc storage units comprising transparent polypropylene are provided. Such storage units exhibit sufficient impact resistance to protect the target disc and sufficient clarity that any informational literature may be placed entirely within the storage unit and easily viewed and read through the walls thereof without impediment. Furthermore, the target storage unit must also include a spine section of sufficient width to permit a section of the informational literature to be placed internally thereon and viewed and easily read (such as, for example, the title and accompanying language describing the target disc placed therein) substantially without impediment as well. Specific novel storage units, in addition to these necessarily transparent walls and spine portions, are also possible to maximize the benefits of the transparent properties thereof.

Abstract: The two stage production of clear, low-haze, injection stretch blow molded polypropylene container articles is disclosed. In the first processing stage, a preform article is manufactured on an injection molding machine. In a second and subsequent step, which may occur remotely from apparatus used in the first step, the preform article is heated and stretch blown into a container. The process may employ the selection of processing parameters to produce preform articles that facilitate stretch blow molding at relatively high rates of speed, while still maintaining an appropriate polypropylene polymer morphology that results in clear, low haze containers.

Abstract: Novel, quick, and reliable detection methods for determining the authenticity of optical and/or audio disc articles (such as compact discs, digital video discs, CD-ROM discs, and the like) are provided. Such a method basically entails the incorporation of an identifier or marking means within the edges of target optical discs or within any other portion of a target disc such that exposure to non-visible light sources will provide the desired identification upon irradiation or detection of the marking means therein. Such an identifier or marking agent thus may be utilized in conjunction with a transparent holding case whereby the needed light source may be exposed through the transparent walls thereof to permit detection of counterfeit or authentic discs without requiring opening of the case itself. Such a method may also be utilized for discs that are removed from or have not been placed and sealed within such a case as well.

Additionally, provided therein are novel insert trays that simultaneously permit proper placement of such internally placed informational literature against the internal portion of the aforementioned walls, and particularly the spine portion, as well as provide antitheft properties.

Abstract: Novel, quick, and reliable detection methods for determining the presence and/or authenticity of optical and/or audio disc articles (such as compact discs, digital video discs, CD-ROM discs, and the like) when present within a holding container are provided. Specific methods of utilizing particular transparent cases are encompassed within this invention. Specific methods of utilizing particular transparent cases are thus also encompassed within this invention as are navel storage unit configurations to maximize the benefits of the transparent properties thereof.
