Patent number: 8774447Abstract: Disclosed is a crossover double speaker having a small speaker and a large speaker on the upper side and on the lower side thereof. The crossover double speaker includes a cover integrally formed on the outer circumference of a flange of the yoke; a frame disposed below the cover; a first speaker unit including a first magnet disposed in a first speaker space, a first vibration plate arranged over the first magnet, and a first voice coil inserted into a first air gap; and a second speaker unit including a second magnet disposed in a second speaker space, a second vibration plate arranged between the yoke and the frame, and a second voice coil inserted into a second air gap. The yoke has sound release holes to output the sound generated from the second speaker unit in the direction of the first speaker unit.Type: GrantFiled: December 6, 2012Date of Patent: July 8, 2014Assignee: Youngbo Engineering Industries, Inc.Inventor: Ju-Heon Ko

Patent number: 5161303Abstract: An insertion tool to be interfaced with a turret-type punch press, or the like, to insert fasteners, such as captive or clinch nuts, into holes in a sheet metal workpiece. The tool includes a canister assembly having a plurality of guide rods on which the captive nuts are stacked. The nuts are loaded from the guide rods into respective holes in a rotatable planetary gear of the canister assembly so that successive ones of said nuts can be axially aligned with an exit opening of the canister assembly to be forcibly ejected therethrough by a punch assembly. The punch assembly and planetary gear are moved relative to the exit opening by a reciprocating cam enclosure which is connected to the punch assembly and to which an impact force is applied from the press. The reciprocating movement of the cam enclosure is transferred to the planetary gear to rotate said gear by way of a motion translating assembly including a rotatable cam that is coupled to and rotated by said cam enclosure.Type: GrantFiled: June 28, 1991Date of Patent: November 10, 1992Assignee: Robotics Automation Consulting Engineering Industries, Inc.Inventors: Scott D. Maynard, Mark H. Becker, Phillip L. Poynor

Patent number: 5016335Abstract: A tapping attachment for threading a relatively large number of holes through a sheet metal part at a relatively low cost per hole. The tapping attachment includes a thrust bearing assembly which is aligned with a turret-type punch press or the like and movable in response to an axially directed force generated by the punch press. The axially directed force applied from the press to the thrust bearing assembly is transferred to a spline shaft. The spline shaft is rotated wihin and moved linearly relative to a screw threaded roller nut, whereby the axially directed force is converted into a rotating force for advancing and turning a tap at high speeds of rotation. A nitrogen reservoir is provided so that a supply of gas is available for returning the thrust bearing assembly and the spline shaft to their initial positions in order that a new hole can be tapped in response to another axially directed force.Type: GrantFiled: April 24, 1989Date of Patent: May 21, 1991Assignee: Robotics Automation Consulting Engineering Industries, Inc.Inventors: Mark H. Becker, Scott D. Maynard

Patent number: 4343398Abstract: A coal tar emulsion driveway sealer is packaged in a sealed bag. The volume of sealer is less than half the capacity of the bag and the bag is substantially completely evacuated but for the sealer. The separated sealer is mixed by compressing the sides of the bag to induce turbulent flow of the paste and liquid for hydraulic mixing thereof. The sealer may be dispensed at a controlled rate without spattering by cutting a corner from the bag to provide a pour spout. The bag with the sealer may be contained in a carton.Type: GrantFiled: August 20, 1980Date of Patent: August 10, 1982Assignee: Engineering Industries, Inc.Inventors: Robert G. Snyder, John J. Clancy, Richard S. Brenneman

Patent number: 4244510Abstract: A bucket-like carton has a polygonal cross section and a flexible bail is connected to handle hinges extending from the upper rim of the carton. An outer wall and an inner reinforcing wall forming the sides of the carton are stamped from a single sheet of corrugated board and are joined by the handle hinges. Tabs on the outer wall fold inwardly to overlap the inner wall. The wall tabs also overlap similar tabs extending outwardly from a recessed bottom and a recessed lid. The several layers of cardboard are stapled at both the top and bottom of the carton. The resultant sturdy carton provides the convenience of a bucket and has high strength at a low cost.Type: GrantFiled: May 23, 1979Date of Patent: January 13, 1981Assignee: Engineering Industries, Inc.Inventors: Robert G. Snyder, Rohe D. Jack, Jr.
