Abstract: A method for manufacturing a wire saw apparatus including a wire supply reel; a long roller; wire guides; a wire winding reel; and a tension arm controlled to move within a control angle of ±A (°) set in advance and configured to apply tension to the wire, the method including the steps of: measuring a surface roughness Rmax of the long roller; measuring an angle a (°) of the tension arm at which the tension arm swings outside a range of the control angle set in advance while the wire is extending from the wire supply reel; calculating R1×2×A÷(|a|+A)=R2, where R1 (?m) represents the measured surface roughness Rmax of the long roller; and adjusting the surface roughness Rmax of the long roller to the calculated numerical value R2 or less. The method for manufacturing a wire saw apparatus can prevent the tension arm from greatly swinging outside the control range.

Abstract: The method is for profiling blades with a belt grinding profiling machine. The blades are mounted into a vise. A vertical position of the template is adjusted by rotating the rotatable knob. The motor is turned on to rotate the grinding belt over the grinding wheel. The guide wheel engages the underside profile of the template. The guide wheel of the template guides movement of the grinding wheel mounted on the common axle by moving the guide wheel along the underside profile of the template. The grinding belt grinds material off the underside of the blade until a portion of the underside profile of the template is copied to the underside of the blade.

Abstract: A reconfigurable surface cleaning apparatus includes a floor cleaning unit comprising a surface cleaning head, and a hand vacuum cleaner. The reconfigurable surface cleaning apparatus is operable in a floor cleaning mode in which the hand vacuum cleaner is mounted to a rigid wand of the floor cleaning unit and operated using an energy storage member of the hand vacuum cleaner, and also operable in an above floor cleaning mode in which the hand vacuum cleaner is disconnected from air flow with the floor cleaning unit and operated using the energy storage member. A cross-sectional area through the rigid wand is less than a cross-sectional area through an upstream portion of an airflow path of the hand vacuum cleaner. A velocity of air travelling through the wand in the floor cleaning mode is greater than a velocity of air flow through the upstream portion in the above floor cleaning mode.

Abstract: A blasting or stripping booth is provided creating a generally downward flow for treatment of fluid and particle flow, which reduces operator exposure to potentially hazardous debris. The booth comprises an enclosure defining an upper region for a workpiece, a lower region, and a separator assembly. In some instances the separator assembly includes individual separator units which are discrete units, each having a generally square or rectangular plan view configuration which are arranged in an array for providing the required process flow capabilities. Further embodiments utilize structures forming the separator which have an elongated trough-like configuration. These embodiments find a particular application in large-scale stripping or blasting booth used in production environments where workpieces may flow through a treatment system in a serial manner. Other suitable applications include batch type processing of parts.

Abstract: A heavy load lifting system is a system that enables a repairman to safely lift and mount different vehicle components for maintenance or repair. The system may include an elongated frame, a wheeled base, a height-adjustment carriage, a telescopic boom, a pivot support assembly, a tilt-adjustment mechanism, and a winch mechanism. The elongated frame enables the height-adjustment carriage to be raised so that the vehicle component can be removed from the vehicle. The wheeled base enables the system to be moved around. The height-adjustment carriage enables the operator to elevate or lower the telescopic boom. The telescopic boom enables the vehicle component to be removed safely. The pivot support assembly provides additional support to the vehicle component being removed. The tilt-adjustment mechanism enables the telescopic boom to position the removed vehicle component at the desired orientation. The winch mechanism enables the height-adjustment carriage to be moved along the elongated frame.

Abstract: The unique aspect of this invention is the fact that the magnet insert screws into the driver shaft head rather than being pressed in under pressure. The best design for this invention includes self-locking threads as well and the combination of using a threaded installation of the magnet insert and the locking threads is an additional unique attribute to this invention. This unique a threaded install attribute helps prevent the magnet insert from coming out under impact pressure and even if it does it allows it to be reinserted using a screwing mechanism and when reinserted will remain in place unlike existing press-in products. A third unique attribute of this invention is the depression at the top of the magnet insert designed to receive a screwing tools such as a flat head or Philips screw driver, hex, Allen, etc., making it possible to easily reinsert the magnet insert and tighten it firmly in place.

Abstract: An upright walk-behind microscrubber apparatus including a handle assembly connected to a base assembly, and featuring an improved handle function. The handle assembly is manipulated by the user to operate the apparatus. The apparatus provides a releasable, lockable, joint assembly that connects the handle assembly to the base assembly, whereby the handle assembly is pivotally connected to the base assembly. The joint assembly permits the handle assembly to be disposed in a fully released configuration in which the handle assembly is freely pivotal relative to the base assembly, or in a fully locked position in which the handle assembly is temporarily locked in an upright orientation. The joint assembly permits the base assembly to be released to a use position generally parallel to the floor, or releasably locked in a storage position generally parallel to the handle assembly but with the base assembly's scrubbing brushes removed from the floor.
