  • Patent number: 7475759
    Abstract: A disc brake for a vehicle wherein first and second friction member have projections thereon that are located in grooves in first and second rails of an anchor. On movement of the first and second frictions members during a brake application, the projections slide in the grooves to maintain a parallel alignment between a braking surface thereon and radial braking surfaces on a rotor and at the same time transmit reactions forces into a rotor to oppose the rotation of the rotor. Braking surfaces on the projections engage the rotor to assist in opposing the rotation of a rotor during each brake application.

  • Patent number: 7472776
    Abstract: An actuator for a drum brake including a plunger connected through a resilient member to a linkage attached to a web on a brake shoe. A rod extends from the plunger and engages a lever arm that is pivotally retained on the web. The lever engages an extendable strut of an adjuster arrangement through which a running clearance is maintained between the brake shoe and a drum. During a brake application, pressurization fluid acts on the plunger to develop an operational force that is communicated through the resilient member to move the brake shoe into engagement with a drum. Should the operational force overcome the resilient member, the plunger moves toward the linkage and a reactive force is applied through the rod that acts through the lever arm to prevent a pawl from rotating such that a current length of the strut and correspondingly a current running clearance is sustained.

  • Patent number: 7437917
    Abstract: A method for determining local departures of opposed friction surfaces that are spaced apart in parallel planes normal to the axis of the rotor. Displacement sensing probes are placed in opposing alignment adjacent the friction surfaces and rotor is spun. Instantaneous distances from each probe to the friction surfaces is made by repetitively sampling and converting the sample distances into digital form. The differences between contemporaneous sample distances are computed to determine rotor thicknesses and displayed. An analog measure of the instantaneous angular rotor position is provided for each instantaneous angular position. The angular rotor position and distance measures are correlated and the angular rotor position sample converted to digital form.

  • Patent number: 7410034
    Abstract: A parking brake including a disc fixed to a vehicle and a plurality of clips attached to the disc to align channels on first and second brake shoes with a braking surface on a drum. Each clip has a rectangular shape with a flat first end fixed to the disc and a U-shaped second end defined by parallel first and second sides separated by a spacer. A projection on the first end is mated with the disc to align the second end along a radial plane of the axis of the drum. The sides of the second end resiliently engage the channels and align friction surfaces on the first and second brake shoes with the braking surface. In addition, the clips attenuate any vibration that may occur between first and second brake shoes and the drum during movement of the vehicle to reducing the creation of noise in the brake.

  • Patent number: 7406799
    Abstract: A system for supporting a household plant includes an electric circuit for selectively moving the plant having a battery and a direct current motor for moving the plant. The motor control is by a first controllable switching device to connect the battery to the motor with a first polarity to cause the plant to move in a first direction, or a second controllable switching device to connect the battery to the motor with a second polarity opposite the first polarity to cause the plant to move in a second direction. A controller selectively enables either the first or second switching devices while leaving the other disabled and in conjunction with a light sensing device and analog comparison circuit precludes actuation of either switching device if inadequate growth promoting light is sensed.

  • Patent number: 7395904
    Abstract: An actuator arrangement for a disc brake for moving first and second friction members into engagement with a rotor and effect a brake application. The actuator arrangement includes first and second levers that are pivotally connected to an anchor located in a plane that is perpendicular to first and second rails on which the first and second friction member are retained, a third lever that is connected to the first lever and a yoke to receive a second end of the second lever and align a first ramp surface thereon with a second ramp surface on its end and an input linkage. The input linkage receives an input force and moves on the first and second ramp surfaces to pull on the first lever and push on the second lever to move the first and second friction members into engagement with the rotor to effect a brake application.

  • Patent number: 7360261
    Abstract: A sofa has a first frame fixed to first and second side members and a mattress with a first section secured to the first frame and a second section located over the first section by a hinge to define a seat that is rotated about the hinge to define a first sleeping surface. A second frame is pivotally attached to the first and second side members with a second mattress attached thereto to define a back for the sofa. A rail is secured to the second frame and engages a beam that extends between the first and second side member to set an incline for the back. The rail is rotated to define a barrier when the second frame is positioned a horizontal plane to define a second sleeping surface. Legs that extend from the second frame engage the side members to retain the second mattress in the horizontal plane.

  • Patent number: 7337825
    Abstract: An electric motor moves drapes on a carrier by a cord wound on a sheave attached to a shaft thereof. The motor is attached to a housing along with a second shaft. The second shaft has an arm on an end thereof and carries a disc with first and second cam surfaces thereon and an axial projection. An arcuate slot on an end cap receives the projection on the disc. In response to an actuation signal, a control activates the motor causing the shaft and sheave to rotate and linearly move the cord and drapes. A limit member on the cord engages the arm and rotates the second shaft causing the first cam to close a first switch and cancel the actuation signal while the second cam closes a second switch such that the rotational direction of the shaft is reversed on receipt of a next actuation signal.

  • Patent number: 7325445
    Abstract: A surface roughness measuring apparatus (11) has a probe (27, 41) with a smooth surface region (31, 43) contoured to conform to a surface (33) the roughness of which is to be measured, and an aperture (25, 49) located generally centrally of the smooth surface region of the probe. Illustratively, the workpiece surface is a generally flat annular surface portion of a disk brake rotor (35). The test probe surface is juxtaposed with the workpiece surface and a fluid pressure modifying mechanism such as an air vacuum pump (15) and driving motor (17), which are coupled to the probe aperture, are energized to induce a fluid pressure differential between the aperture and peripheral portions of the surface region. A fluid parameter monitoring device such as air flow meter (23) or air pressure meter (19) measures a fluid response to the induced fluid pressure differential and the roughness is inferred from the measured fluid behavior.

  • Patent number: 7303242
    Abstract: An adaptation to a vehicle antilock braking system modulator to increase the initial displacement of the master cylinder, provide quicker system response and improved pedal feel. A solenoid assembly is added to the non fluid side of each of the low pressure accumulators in the ABS modulator. Upon the operator initiation of a brake apply, the solenoids are energized to immediately push upon the sump pistons and inject fluid from the low pressure accumulators into the brake system. This extra “shot” of fluid decreases the amount of fluid that the master cylinder delivers to the brake system. This improves pedal feel as it reduces the required initial pedal travel for a given brake system displacement. The low pressure accumulator pistons are spring balanced to ensure retention of fluid between brake applies and to allow normal ABS operation. During ABS operation, the low pressure accumulator displacer solenoids are de-energized to allow effective operation.
