Patent number: 6009782Abstract: A table saw has a motor driven rotary blade disposed in a blade case and vertically adjustable with respect thereto. During cutting, wood chips are expelled from the blade case even when the rotary blade is vertically disposed away from a bottom of the blade case. An air current, provided by a fan driven by the motor, is blown from a motor gear housing and guided to the blade case via a plurality of guide members. The air current subsequently blows along an inner surface of the blade case in order to blow the wood chips out a chip discharge port.Type: GrantFiled: June 18, 1998Date of Patent: January 4, 2000Assignee: Makita CorporationInventors: Nobuo Tajima, Katsuji Haneda, Seiichi Mineda

Patent number: 6000307Abstract: A method of cutting is described, utilizing a specialized utility cutting tool. The tool has a fixed jaw, a movable handle, a blade, and a connecting link. The blade is inserted into a channel formed in the fixed jaw for stability, and is pivotally connected to that fixed jaw. The blade is connected to the connecting link which is connected at an opposite end to the movable handle, so that moving the movable handle toward a handle of the fixed jaw moves the blade. The connecting link provides a mechanical advantage to apply more force to an item to be cut than would be possible without the connecting link. An anvil is mounted in a channel formed in a substantially straight edge of the fixed jaw, and the sharp edge of the blade is moved toward that anvil as the handles of the fixed and movable handles are squeezed together.Type: GrantFiled: February 5, 1998Date of Patent: December 14, 1999Inventor: Robert Wayne Aamodt

Patent number: 5966814Abstract: Disclosed is a tune-producing feeding utensil, such as a spoon or a fork. In the case of a spoon, the spoon mainly includes a metal bowl portion, a plastic handle portion, and a metal back cover. The handle portion is provided with compartments for receiving a circuit board and two serially connected button cells, as well as a shallow groove around the compartments for receiving a gasket. When the back cover is fitted onto the handle portion, the circuit board and button cells are sealed in the handle portion and the gasket is tightly pressed against the shallow groove to make the handle portion watertight. When a baby uses the spoon to feed itself with one hand holding the handle portion at the back cover and its mouth contacting with the bowl portion, an integrated circuit on the circuit board is actuated to cause a tune-producing device attached to the back cover to send out music or voice. The music or voice is helpful in encouraging the baby to enjoy feeding itself concentratively.Type: GrantFiled: January 9, 1998Date of Patent: October 19, 1999Inventor: Michael Lin

Patent number: 5967011Abstract: A device for removal of slips from a continuously transported slip web is composed of an advancement roll pair which continuously advances and holds the slip web. A blade cylinder pushes a respective lead end of a slip into an open gripper of a gripper cylinder. A device is arranged between the advancement roll pair and the blade cylinder and provides transverse perforated lines. A rotating tear-off segment cooperates with the blade cylinder. In order to enable a simple and rapid adaptation to different slip formats, the advancement speed of the advancement rolls, the transverse perforating device and the angle of action of the tear-off segment are correspondingly changed relative to the blade cylinder.Type: GrantFiled: October 17, 1996Date of Patent: October 19, 1999Assignee: Windmoller & HolscherInventors: Richard Feldkamper, Rudiger Duwendag

Patent number: 5957022Abstract: A workpiece-supporting fence has a pair of movable fences movably attached to a fixed fence which is secured to a base of the device in which the fence is being used. The pair of movable fences are located on opposite sides of a working tool such as a saw blade. A fixed clamping arrangement is associated with each movable fence and provides a single point actuation member for each movable fence to clamp the movable fence to the fixed fence such that the movable fence is vertically aligned and flush with the fixed fence. In one embodiment, each movable fence is provided with a gap-filling flap which is pivotably secured to the movable fence to be movable between a lower and an upper position. In its lower position, the gap-filling flap minimizes the gap between the movable fence and the working tool. In its upper position, the gap-filling flap provides additional support when working with taller or thicker workpieces.Type: GrantFiled: September 4, 1997Date of Patent: September 28, 1999Assignee: Black & Decker Inc.Inventors: William R.
