Title: Laser welding unit
Inventor: SCHLATTER HOWARD M
IPC: B23K26/02
Filed: 1992-04-29
Granted: 1994-12-06
Abstract: LASER WELDING UNIT                          ABSTRACT          A laser welding head carried by a robotic arm welds sheet metal workpieces to each other along an elongate seam while maintaining a precise focusing of the laser beam on the seam as it is formed in the face of minor variations in the dimensions, shape and positioning of successive workpieces.  The head includes a workpiece gripping assembly including a fluid pressure actuated motor having its cylinder coupled to one of two workpiece engaging members and its piston rod coupled to the other to shift the members between an open workpiece release position and a closed workpiece clamping position in which the assembly clamps the two workpieces fixedly against each other with a clamping force determined by the pressure applied to the motor.  The gripping assembly is movably mounted upon a base member fixed to the robotic arm.  When the workpieces are clamped by the assembly, at least one of the workpieces is engaged by a roller carried on one of the workpiece engaging members, and a laser beam focusing unit carried by that workpiece engaging member focuses the beam precisely on the surface of the roller engaged workpiece. The robotic arm moves the workpiece engaging member along the seam by rolling the roller along the workpiece surface. The workpiece gripping assembly is movable as a unit relative to the base member to "float" along the seam as may be required by deviations of the roller engaged workpiece surface from its intended position.

Title: Wavelength-assignable optical communication system
Inventor: YASUI TADAHIKO
IPC: H04B10/27
Filed: 1992-05-08
Granted: 1998-06-30
Abstract: An optical communication system wherein a wavelength used by a terminal for transmission and reception is assigned thereto in accordance with a call request from the terminal.           When the terminal makes a call request at a control wavelength, a wavelength control unit selects a wavelength to be used by the calling terminal out of the wavelengths unused on a wavelength-multiplex communication path, and informs the terminal of the selected wavelength at the control wavelength.  The terminal adjusts the wavelength of transmitting and receiving circuits to the informed wavelength.           As an example of the optical communication system is disclosed a wavelength-sharing optical exchange system.    A connection request from a terminal is transmitted through a wavelength-multiplex communication path at a control wavelength.  The wavelength is directed through a subscriber line control unit to a network channel control unit.  The network channel control unit retrieves a wavelength table contained therein to decide if the terminal at the other end is available.  If the called terminal is available, the network channel control unit selects a usable wavelength out of the wavelengths recorded on wavelength table and sets a switchboard such that the switchboard can operate at the selected wavelength.  Further, the network channel control unit informs the calling and called terminals of the selected wavelength at the control wavelength via the subscriber-line control units.  Both of the terminals then set transmitting and receiving wavelengths to the selected wavelength.

Inventor: LEOPOLD EDMUND A
IPC: B29C48/05
Filed: 1994-01-07
Granted: 1997-12-30
Abstract: A glazed unit having three sheets includes a pair of outer glass sheets secured to outer legs of a spacer having a generally U-shaped cross section.  On the base of the spacer between the outer legs is provided a layer of pliable material having a generally U-shaped cross section and having a desiccant therein.  A third or intermediate glass sheet has its edge portion in the groove formed by the layer of pliable material.  Movement of the third sheet toward an outer glass sheet is limited by the cooperation of the layer of the pliable material and portion of the outer legs of the spacer at the corners of the unit bent inwardly to move the layer of pliable material at the corner toward the unit during fabrication of the unit.          A nozzle for depositing the shaped layer of the pliable material includes a platform having a shaping tip. The shaping tip has converging sides at one end and generally parallel sides at the other end.  The portion of the tip at the first end has a lower elevation than the portion of the tip at the second end.  Holes for moving the pliable material are provided in the platform on each side of the tip and in tips intermediate its ends. The different elevation and converging end minimizes if not eliminates tailing.          A method is also discussed for making the triple glazed unit using the nozzling to provide the shaped layer of pliable material.  An injector arrangement fills the unit with an insulating gas e.g. Argon.

Title: Thermoplastic multilayer composites
Inventor: JADAMUS HANS
IPC: B32B1/08
Filed: 1994-01-28
Granted: 2000-02-22
Abstract: A thermoplastic multilayer composite material is disclosed. The composite comprises at least a first layer made of a moulding compound base on a polyvinylidene fluoride and a second layer adjacent to the first layer, which second layer is made of a moulding compound based on a mixture of a polyamide and a polyglutarimide. The two layers are adhesively bonded to one another. The composite has an outstanding resistance to and barrier action against diffusion of chemicals, solvents and fuels. Since the layers are adhesively bonded to one another, no delamination occurs on thermal expansion or flexing of the finished part. The composite is used in structural parts, particularly in electrical, engineering and automobile industries, where the barrier action of the polyvinylidene fluoride needs to be combined with the good mechanical properties of polyamide.
