  • Patent number: 6871371
    Abstract: A floor care method and machine are disclosed, wherein a replaceable floor care element (e.g., a cleaning pad, a brush, a polishing pad, etc.) is easily attached to and detached from the rest of the machine. For attaching the floor care element, an operator positions the machine (minus any floor care element) over the such an element so that components on the machine and/or the floor care element cause the floor care element to operationally align with the rotatable drive of the machine so that rotation of the drive in the direction used during floor care operations causes the floor care element to securely attach to the drive. Alternatively, to detach the floor care element, the direction of rotation can be reversed. The machine can then be tilted upwardly onto its rear wheels and rolled to a location where the floor care element is not underneath the rest of the machine.

  • Patent number: 6865772
    Abstract: An applicator used to evenly apply liquid tire dressing to the entire outer sidewall of a tire. The applicator includes a pad that includes an elongated, concave, curved lower surface that is complementary in shape with a portion of the sidewall. The pad includes at least one beveled, concave lateral edge that enable the tire dressing to be applied evenly to the areas of the sidewall adjacent to the wheel hub and to the compressed shoulder area of the tire adjacent to the ground. The pad is attached to a rigid base that includes a rigid handle aligned parallel to the longitudinal axis of the pad and rigid base and that allows the user to easily hold the applicator perpendicular to the sidewall and move the applicator in long broad strokes in a circular pattern around the sidewall of a tire. An optional holding tray is also provided that temporarily stores the applicator and prevents the tire dressing from drying out.

  • Patent number: 6863790
    Abstract: A simple and rugged sheathless interface for capillary electrophoresis/electrospray ionization-mass spectrometry (CE/ESI-MS) was designed using common laboratory tools and chemicals. The interface uses a small platinum (Pt) wire which is inserted into the CE capillary through a small hole near the terminus. The position of the wire inside the CE capillary and within the buffer solution is analogous to standard CE separation operations where the terminus of the CE capillary is placed inside a buffer reservoir along with a grounded platinum electrode. By combining the use of the in-capillary electrode interface with sharpening of the fused silica tip of the CE capillary outlet, a stable electrospray current was maintained for an extended period of time. The design was successfully applied to CE/ESI-MS separations and analysis of mixtures of peptides and proteins. A detection limit of approximately 4 femtomole (S/N=3) was achieved for detection of myoglobin utilizing a 75 ?m-i.d.

  • Patent number: 6857158
    Abstract: An apparatus for removing deposits from the interior surface of a conduit while being advanced through the conduit by virtue of pressurized upstream liquid includes front and rear assemblies interconnected in a manner to permit limited movement there between. The rear assembly contains a mechanism for receiving the upstream liquid and increasing its pressure. The liquid of increased pressure is fed to a rotating nozzle in the front assembly. High velocity water jets emergent from the nozzle strike the interior surface of the conduit to dislodge deposits. A resilient sidewall in one or both assemblies expands by virtue of the liquid of increased pressure to apply a controlled braking force against the interior surface of the conduit.
