Abstract: Methods and apparatus for forming a multi-layered tire component, the steps of the method including providing a mechanical system, the system including a plurality of cutting members; translating a sheet of material along a translation path through the mechanical system; cutting a first strip from the sheet with one or more of the plurality of cutting members, this step occurring during the step of translating; mechanically applying the first strip to a building surface, this step occurring during the step of translating; cutting a second strip from the sheet subsequent to the step of cutting the first strip, this step occurring during the step of translating; mechanically applying the second strip to a building surface, this step occurring during the step of translating.

Abstract: Apparatus to cause a running length of yarn to vibrate at its harmonic frequency and to electronically measure the harmonic frequency thereof to provide a signal which can be employed to maintain and/or correct the parameters of the system to maintain a desired tension in the yarn being run.

Abstract: A new and improved brush for a carpet scrubber with a flat, even continuous outer bristle extremity.

Abstract: An improved carpet cleaning machine which incorporates controls to allow it to be employed as either a carpet scrubber or a vacuum cleaner. The carpet cleaning machine incorporates a novel handle arrangement which can be collapsed for storage and handling.

Abstract: A powder dispensing device having a powder storage bin with a powder discharge area, a perforated drum rotatably mounted within the bin adjacent to the powder discharge area and a wiper blade mounted within the drum and engaging the interior surface of the drum near the powder discharge area.

Abstract: A device for scrubbing surfaces having two crank-rocker mechanisms wherein a scrubber element is mounted on the rocking link of each crank-rocker mechanism, the scrubber elements having recessed portions arranged so that as the crank-rocker mechanisms operate, the scrubbers scrub overlapping areas but do not collide.

Abstract: A device for scrubbing surfaces having pairs of freely rotatable brushes each mounted on a shaft having an offset tip portion. Each shaft is mounted on a rotating support plate and half of the shafts rotate clockwise and the other half rotate counter-clockwise. In the preferred embodiment, the scrubbers have slanted bristles which bias the rotation of each scrubber in the direction of rotation of the shaft it is mounted upon. The preferred embodiment is particularly well suited for use in cleaning carpets using the powdered cleaning composition described in U.S. Pat. No. 4,013,594.
