Abstract:
A method (e.g., for creating a printing plate assembly of an ink jet print head assembly) includes coating one or more sides of plural planar subsection plates with a bonding material. The subsection plates include printing holes through which a fluid is to be ejected from the ink jet print head assembly. The method also includes placing the subsection plates of the printing plate assembly against each other with the printing holes axially aligned with each other and heating the bonding material between the subsection plates such that the subsection plates are affixed to each other. The subsection plates are coupled with each other to form a chamber printing assembly that is coupled to the ink jet print head assembly that prints fluid onto one or more objects by ejecting the fluid out of the printing holes of the subsection plates. The subsection plates may be hermetically bonded to each other by inductively heating the assembly.
Abstract:
The present invention relates to a hybrid drive shaft using friction-stir welding and a fabrication method thereof, and more particularly to a drive shaft comprising a metal tube, a composite material layer formed inside the metal tube, and a metal yoke connected to both ends of the drive shaft by means of friction-stir welding so as to make the components simple and lightweight and to enhance the durability, and a fabrication method thereof. The fabrication method comprises the steps of: shaping a composite material sheet into a cylindrical form by means of a mandrel; bonding the cylindrical composite material layer to the inside of a metal tube by rotating the mandrel snugly inserted in the composite material cylinder; maintaining the inside of the metal tube in a vacuum state for a given duration so as to make the composite material layer stick to the metal tube; heating the metal tube maintained in the vacuum state in an autoclave so as to mold the composite material; and adjoining a connection member for connecting other parts to the ends of the metal tube by friction-stir welding.
Abstract:
The invention relates to a method for producing a tight dual-component part (1) for an assembly subjected to an ultra-vacuum, the part (1) comprising two components (3, 4), where said components comprise different metals or metal alloys. The invention consists of a first step of mechanical assembly of the two components (3, 4), and a second step of friction stir welding on a closed path formed at the interface between the two components (3, 4).
Abstract:
An automated container cutting apparatus configured to cut various sized rectilinear containers without unnecessary costs or lack of transportability. The automated container cutting apparatus includes a right angle transfer conveyor that positions a container in a first cutting position. The apparatus also includes a cutting mechanism configured to cut the container on two adjacent edges while in the first cutting position. The cutting mechanism further includes two cutting elements supported at right angles to one another for horizontally cutting a container on two adjacent edges.

Abstract:
The present invention provides a welding technology that allows stable welding even if a thin wire is used as a leading electrode in multiple-electrode submerged arc welding, particularly if welding is performed under welding conditions involving high wire feeding speed, or even if a flux-cored wire is used in which large winding remains after straightening. Provided are a welding torch, for use with a leading electrode in multiple-electrode submerged arc welding, that includes a contact tip, a connector for a power cable, a tube-shaped conductor disposed therebetween, and means for insulating the tube-shaped conductor from an electrode wire, and a multiple-electrode submerged arc welding method using such a welding torch.
Abstract:
The invention relates to a method for producing a housing (100-125) with at least one hermetically sealed receiving space (12, 19, 20) for an electronic component (3), said receiving space comprising at least a part of the interior of the housing (100-125). In the method, a hollow body (2) made of glass and having at least one opening is produced/provided, at least one electronic device (3) is introduced through the at least one opening, and the receiving space (12, 19, 20) is hermetically sealed by melting the housing (100-125), or the at least one opening is sealed by means of laser radiation. The invention further relates to a device with an at least partially hermetically sealed housing (100-125) made of silicon, particularly a housing produced according to the above-mentioned method.
Abstract:
A method of forge welding includes placing at least two components for welding together, adjacent each other and with an exothermic flux mixture placed between the components. The exothermic flux mixture is heated to initiate an exothermic reaction and the faying surfaces of the two components are pressed together. The components being welded may be tubular, in particular pipes. Apparatus for the method of forge welding and exothermic flux mixtures for the method of forge welding are also provided.
