Abstract: A vibrator motor has a stationary piece and a moving piece hinged at one end. The moving piece does not generate substantial internal spring forces under the influence of an electromagnetic field, because it does not have a tail bracket. Other parts of conventional motors are also eliminated, so the motor is easier and less expensive to manufacture. In addition, the motor can be assembled and tuned before installation, which increases the ability to automate assembly.

The second section of the housing forms a path for the dust particles.

Abstract: A computer controlled all-in-one reel mower sharpener and roller alignment system can be rolled under a mower to be conditioned. No removal of the cutting unit is needed. A linear voltage displacement transducer (LVDT 715 or a mechanical dial indicator 7155; alternatively a friction wheel 7150 with a rotary encoder 7151 may be used, or any combination of sensors 715, 7155, 7151) or equivalent instructs the machinist how to align the front and rear rollers in parallel. A laser scanner or probe determines the location for the cutter, and then the machining head sharpens each blade automatically. A separate cutter sharpens the bed knife. Most all mowers can be conditioned based on the laser or probe calibration of the blade size. The laser or probe measures the height of cut by sensing the blade location.

Abstract: A method for manufacturing a handsaw capable of cutting a glass bottle. The method includes cutting a steel strip to a predetermined length to form a handsaw substrate. A portion of the handsaw substrate, other than a cutter blade forming portion formed on at least one edge of the handsaw substrate in a widthwise direction is masked. A hard abrasive is applied onto the portion of the handsaw substrate other than the masked portion. The handsaw substrate, to which the hard abrasive has been applied, is dipped in an electrolytic solution tank to deposit a metal layer in which the hard abrasive is embedded.

Abstract: A resilient hand guard for protecting the hand of a hacksaw user including a flat shield formed of resilient non-metallic or elastomeric material having a height equal to that of the frame and a width at least as great as a projected frontal width of a user's hand when grasped around the handle.
