Abstract: An intermittent air discharge apparatus has a main valve and a pilot valve, the main valve being switched between a discharge state and a discharge stop state. The pilot valve is switched between an air-supply state to supply air to a pilot chamber for air-discharge, and an air-supply stop state. When the pilot valve is switched to the air-supply state, an exhaust passage communicates with the pilot chamber for air-discharge. When the pilot valve is switched to the air-supply state, a supply or exhaust passage allows an air supply passage to communicate with the pilot chamber for air-discharge and a pilot chamber for stopping air-supply; when the pilot valve is switched to the air-supply stop state, communication with the air supply passage is blocked. A flow rate of air from the pilot chamber for air-discharge is set by the exhaust passage, and a flow rate of air from the pilot chamber for stopping air-supply is set by the supply or exhaust passage.

Abstract: Inexperienced users of conventional self-drilling drywall anchors may apply too much torque to its screw drive, even after the anchor has become fully bedded down in the drywall, under the mistaken impression that applying a greater torque will improve security of the anchor within the drywall. However, continuing to rotate the anchor after it has been fully inserted into the dry wall continues to rotate the anchor within the drywall and gouges out drywall material from around the anchor. Such gouging causes a cavity to form around the anchor, reducing its security within the wall. The present invention provides a self-drilling drywall anchor having a screw drive 16 that comprises a clutch configured to limit an amount of torque transmitted to the shank 5 by a tool engaged with the screw drive 16.

Abstract: A magnetic bearing retains a rotatable shaft in a selected position by magnetic coupling between two circularmagnetic assemblies, one of which is connected to the shaft. Each magnetic coupling completes a magnetic circuit. Shaft rotation does not affect the magnetic circuit, but radial displacement of the shaft disrupts the magnetic circuit and increases magnetic reluctance. Increasing magnetic reluctance inhibits radial displacement. The shaft thereby supports a load while rotating freely, constrained to a selected position by forces of magnetic reluctance. A bearing may be employed to maintain gap distance between the magnetic assemblies.
