Abstract: A surface blasting apparatus for treating a surface with abrasive, cleaning dust and debris from abrasive rebounded from the treated surface so that the abrasive may be reused, and separating the debris from the air. Air and debris flow through abrasive rebounded from said surface and through a baffle system which prevents abrasive flow therethrough. A row of magnets is positioned adjacent the baffle system for receiving and arresting abrasive exiting an abrasive return chute. A mechanical conveying system lifts abrasive upwardly so that it falls toward an abrasive storage hopper. The abrasive falls in the form of a curtain through which air exiting the baffle system passes. The air and dust contained therein enter a prefilter in a first cleaning chamber and heavy dust falls downwardly therefrom. The air flows from the prefilter into a second cleaning chamber where it is filtered so that light dust is removed therefrom and falls downwardly.

Abstract: A device for sharpening a single flute countersink in which a threaded shaft is mounted in an enlarged opening formed at the upper end portion of an upstanding post. One end of the threaded shaft mounts a countersink to-be-sharpened, while the other end has a knurled portion to allow for the manual rotation of the shaft. A collar is provided adjacent to the knurled end of the shaft which collar has a projecting pin that cooperates with a projecting pin from the side of the upstanding post, to thereby limit the arcuate rotation of the shaft and attached countersink to less than 360.degree., in accordance with the arcuate extent of the cutting surface of the single flute countersink. Upon sharpening of the countersink, it is simultaneously rotated and translated in one direction, in accordance with the geometry of a single flute countersink.

Abstract: A ratchet-action open-end wrench having jaw portions one of which is translationally movable on a handle end along an oblique path, between nut-gripping and nut-releasing positions. Biasing means urges the movable jaw portion toward its jaw-gripping position, wherein cooperable, separable interfitting means on said handle and jaw portion tend to resist shifting of the latter to the nut-releasing position. For such condition, the movable jaw portion is set, and the wrench is thus conditioned to drive the nut when the handle is swivelled forward. The movable jaw portion in addition to its main translational movement, can initially rock slightly to disengage the interfitting means, such rocking being effected by a backward movement of the handle whereby translational shifting of the jaw portion can occur to the nut-releasing position which then permits a bypass or ratchet action of the wrench to be had for obtaining a new, advancing grip on the nut.

Abstract: A corkscrew comprises a sleeve coaxial with a corkscrew spiral and formed to cooperate with a bottleneck provided with a cork. An electric motor drives the corkscrew spiral by means of a reduction gear, the corkscrew spiral being capable of being screwed into the cork in one direction of rotation with the cork being drawn from the bottleneck without the direction of rotation being reversed, the reduction gear providing a reduction ratio of 60:1 to 100:1, the electric motor being a self-starting two-pole single-phase synchronous motor with a diametrically magnetized permanent-magnet rotor. A reversible unidirectional latch is situated at the driven side of the corkscrew spiral for defining the direction of rotation of the motor, such unidirectional latch cooperating with a part of the reduction gear driven by the motor with an integral reduction ratio. Provision is made to reverse the blocking direction of the unidirectional latch to select one of the two directions of rotation of the motor.
