An apparatus for applying weld metal for the purpose of hard-facing of metal plates and a method of operation of the apparatus. A metal plate is moved through an apparatus in which there are weld heads including welding electrodes. The metal plate has a slight induced convexity in the region of the welding heads so that an accurate distance is maintained between the welding electrode and the surface of the metal plate. The convexity is formed by a wheel assembly under the plates and the wheel as...

A method of overlaying by a laser beam, comprises the steps of: relatively moving and irradiating a laser beam with respect to a base metal and simultaneously putting an other metal material than the base metal material on the base metal surface; and forming an overlay layer by melting the other metal material, wherein the overlay operation is performed in such a manner that an inclined angle .theta. with respect to the base metal surface of the beginning end portion surface becomes a range of 8...

A trim molding for attachment to a vehicle includes a core member having an outer periphery less than a predetermined thickness. An end is formed at each end of the core member. An outer layer is molded about one side of the core member and ends to form a smooth continuous surface to the predetermined thickness and to prevent a joint line from visually appearing between the ends and the core member in the outer layer.

An improved pad or liner for overlaying a mattress, including at least one panel having a flexible thermoplastic elastomeric honeycomb core encased within a permeable fabric covering. The honeycomb core is formed of undulated strips of resilient thermoplastic material, thermal compression bonded together to form cell walls defining a plurality of contiguous regularly shaped cells having an upper and a lower extremity. The cell walls of the core are formed with a plurality of perforations. The up...

A normal video signal and an overlay video signal are combined by supplying the normal video signal to the base of a first emitter follower transistor while the overlay video signal is supplied to the base of a second emitter follower transistor. The two transistors are biased such that the first transistor is at a slightly lower voltage than the second (overlay) transistor and is reversed biased (off) any time data is available from the overlay video signal.

The bedding article includes three fabric sections having approximately the same size and positioned in registry. Two fabric baffle strips extend in one dimension between and connected to upper and middle fabric sections, defining three interior chambers therebetween. Two fabric baffle strips extend in a dimension perpendicular to the dimension between and connected to the lower and middle fabric sections, also defining three chambers therebetween. Loose filling is placed into all of the chamber...

A video system is disclosed which is capable of receiving digital data from a source such as a video camera, and subsequently transferring the received data into a main frame buffer for display on a video display, where the data from the source can overlay a primary image stored in the main frame buffer. An auxiliary frame buffer, consisting of a bank of dual-port RAMs, receives the data of the overlay image via its serial port and transfers this data into the randomly accessible array therein. ...

An overlay for a sectional garage door extends between adjacent panel sections of the door. The overlay has a plurality of members made of extruded polystyrene. The overlay members extending from one section of the door to an adjacent section are cut along the centerline between door sections to allow the door to open and close and provide an aesthetically pleasing and professional appearance without gapping.

A powder material for powder plasma build-up welding which exhibits excellent resistance and bending properties comprises C in an amount of 0.06 to 0.15% (% by weight, the same hereinafter), Si in an amount of 0.2 to 1.0%, Mn in an amount of 0.2 to 1.0%, Cr in an amount of 17 to 30%, Nb in an amount of 0.6 to 1.5%, Ni in an amount of not more than 0.5%, and the balance consisting of Fe and unavoidable impurities.

An improved apparatus and method for creating high quality virtual reality panoramas is disclosed that yields dramatic improvements during the authoring and projecting cycles, with speeds up to several orders of magnitude faster than prior systems. In a preferred embodiment, a series of rectilinear images taken from a plurality of rows are pairwise registered with one another, and locally optimized using a pairwise objective function (local error function) that minimizes certain parameters in a ...
