  • Patent number: 5887311
    Abstract: A flat mop head for cleaning floors includes a cover panel with structure fastening on its top surface and a highly absorbent material at least partially made of cotton and/or viscose in the central area of its bottom surface. At least the longitudinal sides of the cover panel are provided with a hem. A textile rim both at least partially surrounds the edges of the cover panel, and forms the hem. The cover panel consists of at least partially mixed yarns made of synthetic and natural fibers.

  • Patent number: 5873946
    Abstract: An installation for lubricating, cleaning and/or disinfecting conveyor belts for containers, more particularly for foods, such as bottles, glasses, cans, bags and the like, comprising a central metering station connectable to a water pipe used to dilute a concentrated lubricant, cleaner or disinfectant, and several distributing pipes connected to the metering station lead to the points of use. At each point of use there is a mixing valve (13-19) connectable to distribution line (52) and the water pipe (23) and individually adjustable for each point of use and a pressure reducer (50, 51) fitted upstream of each mixing valve. Varying concentration can be provided for each point of use (31-37) with little technical complexity. In another embodiment, the invention is the process carried out by the installation.

  • Patent number: 5785210
    Abstract: A dispenser container for a paste is provided. The dispenser container is formed from a cylinder open at one end for holding the paste, a displaceable tightly fitted follower plate means is arranged at the open end of the cylinder and a dispenser for transporting the paste from the container is arranged to cooperate with the follower plate. A motor and transmission are mounted near the center of the follower plate and has a shaft which extends through the follower plate and has mounted thereon a multiple blade stirrer. The stirrer rotates in the paste below the follower plate. The dispenser removes the paste from the container at a position away from the center of the follower plate in an area below which the multiple blade stirrer rotates. The multiple blade stirrer by rotating in the paste lowers the viscosity and permits the paste to be more easily transported from the container by the dispenser.

  • Patent number: 5768742
    Abstract: The invention concerns an improvement to a movable floor cleaning machine with integral clean and dirty liquid compartments which are separated from each other by a solid partition with an opening which allows liquid to pass through, and is provided with a closure member which can be opened. By virtue of the improvement, the floor cleaning machine is easy to handle and functions reliably both for recycling cleaning liquids and in normal operation. The closure member which can be opened is a valve body which is resiliently urged from one side of the partition towards the edge of the opening in the closed position. On the other side, and in the region of the opening, the partition is provided with a tubular coupling connection to one end of which a tubular coupling with an associated filter can be coupled.

  • Patent number: 5765724
    Abstract: A method for emptying a substantially, completely compressible container filled with a thixotropic paste, for example, a paste-form detergent. The thixotropic paste is transported by compression by a compressive force of the container toward an opening of the container and through that opening into a connected delivery tube. The compressive force is applied to a limited area of the container to deliver the thixotropic paste which is then transported by a metering pump through the delivery tube to a mixing container where it is mixed with inflowing water.

  • Patent number: 5680667
    Abstract: A floor-cleaning mop head includes an oblong textile base fabric with, attached to the top at both ends, slide-in pockets for the head-holder and, attached underneath, material designed to collect moisture and dirt in the form of hair tufts, fringes, loops, foam-rubber strips, and so forth. The oblong base fabric consists, at least in the zone of the slide-in pockets, of a material which is more highly heat-shrinking than the textile material of which the pockets are made, in order to ensure that the pockets on top of mop remain open even after repeated washing of the mop head, without effecting other useful characteristics of the mop.
