Abstract: A parking brake system for vehicles, in particular heavy-duty vehicles, is provided. The parking brake system has a parking brake actuator having an actuation pushrod slidably housed within an actuator cylinder and adapted to act on a release mechanism of a vehicle brake for unlocking the vehicle brake, and a hydraulic pump operated by an electric motor, adapted to deliver a flow of fluid into the actuator cylinder for moving the actuation pushrod.

Abstract: A fire-retardant webbed apparatus for use on a structure includes at least one tube surrounding a channel; at least one inlet port on the at least one tube, the at least one inlet port being in fluid flow communication with the channel, and the at least one inlet port being sized and configured for receiving a flow of fluid; a plurality of apertures formed along the length of the one or more tubes, the plurality of apertures each being in fluid flow communication with the channel; and wherein the flow of a fluid into the channel through a selected one of the at least one inlet ports causes the fluid to be emitted through plurality of apertures onto the structure and surrounding area for preventing the spread of fire onto the structure.

Abstract: A mixer for use in combination with a bucket and a drill includes an annular rim sized and configured for selective attachment to the bucket; a mixing extension component, the distal end thereof including blades for mixing one or more liquids in the bucket; an opening on the annular rim, the opening being sized for passage of the mixing extension component; a connector component configured for attachment to the distal end of the mixing extension component; a rim member of the connector component configured for being secured about the interior opening of the annular rim for stabilizing the mixing extension component; a manual rotating component; an adapter component configured to be secured to the connector component; and wherein a user can selectively and interchangeably operate the mixer using the drill and the manual rotating component.

Abstract: A sleeve for use in combination with a tape measure includes an elastomeric main body surrounding a cavity, the main body being sized and configured for snug fit engagement of the tape measure; a plurality of openings formed on the main body; a first one of the plurality of openings surrounding a tape opening of the tape measure, such that the tape may be selectively passed therethrough; a second one of the plurality of openings for surrounding a tape measure control of the tape measure, such that the tape measure control may be selectively actuated therethrough; a third one of the plurality of openings for surrounding a clip of the tape measure, such that the clip may be selectively operated therethrough; a metallic plate being structured and disposed for magnetically securing a magnet element of a writing instrument; and a pocket for receipt of the writing instrument.

Abstract: A high flow vacuum check valve incorporates a plurality of rubber dampening feet located on the sealing bead side of the valve poppet. The feet extend axially slightly beyond the sealing surface of the sealing bead so as to have an axial compression interference, the feet first engaging the valve seat as the valve poppet moves from its open position toward its closed position, and then compressing as the valve poppet continues its movement until the valve is fully closed with the sealing bead in full sealing engagement with the valve seat. This interference compression causes the feet to perform as rate changing springs so long as they are compressed to any extent, dampening axial movements of the valve poppet, and also act as stabilizing members on the valve poppet in the lateral plane. The feet may also be constructed with tiers which also contribute to the stability of the valve poppet.

Abstract: Resilient side loading of vacuum brake booster check valves to inhibit valve pulsations and resulting valve noises generated by pulsations from the vacuum source.
