Title: Automatic tracking process of the joint bevel for the butt welding of pipes and equipment for the embodiment of the process
Inventor: BELLONI ANTONIO
IPC: B23K9/02
Filed: 1998-05-26
Abstract: The present invention relates to an automatic tracking process of the joint bevel for the butt welding of coaxial pipes operating with orbital movements, which allow the deposit of a number of passes of welding material to produce material continuity between these with the formation of a welded joint without "side of lack  fusion"  defects.  The  present  invention  also relates to equipment for the embodiment of the process which substantially consists in continuously observing the electrical parameter values relating to the voltage, current and voltaic arc impedance and comparing these values with sample values fixed and preset in a governing unit, which activates the driving source for the orientation of the welding torch  in the joint bevel.

Title: Power generator driven by environment's heat
Inventor: BOLESTA DMYTRO
IPC: F03B3/02
Filed: 1997-08-07
Abstract: If rotor blades have such form that between them are formed channels which have between their inlets and outlets a narrow cross section, then when the rotor rotates a fluid flowing from the inlet into the narrow cross section accelerates reaching there an increased velocity which is so directed that the reaction of fluid's momentum drives the rotor then the rotor generates power consuming fluid's mechanical energy and when the fluid flows from the narrow to increasing cross section of the channel said momentum is absorbed by the downstream increasing fluid's pressure whereat the fluid converts its own heat directly into its mechanical energy which equals the sum of the energy which drives the rotor and the kinetic energy of the fluid issuing from the channels whereat the fluid issues from the channels correspondingly cooled.

Inventor: SEILER LARRY D
IPC: G06T7/00
Filed: 1998-05-29
Abstract: A graphics system for storing and editing graphic images represented by digital data, includes a frame memory for storing pixel data representing graphic images including first and second graphic objects.  The pixel data is stored at addresses, each being associated with one or more graphic fragment forming the first and second graphic objects.  First and second addresses are respectively associated with those of the graphic fragments forming the first and second graphic objects.  A memory controller controls writing and reading the pixel data to and from the frame memory.  A fragment editor is provided to receive the pixel data read from the first address and modify the associated fragment with the received pixel data so as to form modified pixel data.  An address detector detects the first address responsive to a request to read the pixel data from the first address and the second address responsive to a subsequent request to read pixel data from the second address.  The detector compares the detected first and second addresses to identify an overlap of the first and second graphic objects.  If an overlap is identified, the controller controls the writing of the modified pixel data to the first address before the reading of the pixel data from the second address.

Title: Apparatus for automatic layout and cutting corner lines in stone
Inventor: CETRANGOLO DOLIVIO L
IPC: B27B31/06
Filed: 1998-08-25
Abstract: An apparatus or machine is disclosed for automatic establishing and cutting the corner lines in a piece of stone. The machine includes two pairs of saw blades, each pair disposed on opposite sides of the stone. The saw blades are adjustable in two directions with respect to each other to properly locate the saw blades with respect to the four corners of the stone. Laser light sources are positioned to provide light beams down onto the piece of stone at the precise location of the outer edge of the saw blade. The laser light sources assist the machine operator in properly positioning the stone with respect to the saw blades. Once the stone is properly located, the saw blades are moved into cutting engagement with the stone. After the four corner lines of the stone have been cut, these corner lines precisely establish the dimensions of the rectangles on the top and bottom stone surfaces, and the four vertical corner lines connecting the two rectangles.

Abstract: L'invention porte sur une amélioration concernant l'utilisation d'une fonction de boîte t permettant d'effectuer un cryptage à l'aide d'un algorithme de cryptage de messages cellulaires (CMEA). Des décalages se produisent qui sont destinés à l'application de la fonction de boîte t à un message, au moyen de valeurs secrètes et d'octets de messages préalablement cryptés. On utilise ces décalages pour permuter le message pour pouvoir lui appliquer la fonction de boîte t. Pour le premier message d'un appel, les octets de messages préalablement cryptés sont remplacés par une valeur de démarrage. Dans un système mettant en oeuvre une seule itération de cryptage CMEA, des premier et second décalages se produisent. Dans un système mettant en oeuvre deux itérations de cryptage CMEA, des premier, second, troisième et quatrième décalages se produisent, les premier et second décalages étant utilisés dans la première itération de cryptage CMEA, et les troisième et quatrième décalages étant utilisés dans la seconde itération de cryptage CMEA.

Title: Method for hardfacing a metal surface
Inventor: REVANKAR GOPAL S
IPC: C23C24/08
Filed: 1997-08-21
Abstract: A wear-resistant hardfacing and a method for applying such a hardfacing is taught herein. A finely powdered, wear-resistant alloy and a polyvinyl alcohol (PVA) solution slurry is coated onto the metal surface of a tool, implement, or similar item to be hardfaced. Alternatively, a binding coating of PVA solution may be applied to the metal surface followed by application of a layer of a powdered alloy. After the slurry or PVA binding coating has dried, leaving a dry coat of alloy in a PVA matrix, the metal surface is heated to the fusion temperature of the alloy in vacuum, in an inert gas atmosphere, or in hydrogen atmosphere. The metal item with the fused coating is heat treated to impart desired mechanical properties to the part substrate material. The method of the present invention gives a smooth, dense coating of the wear-resistant hardfacing without nonmetallic inclusions.
