A method for forming a sealed floating roof for a storage tank is disclosed. A plurality of roof panels are positioned adjacent to one another such that respective depressions of adjacent roof panels disposed adjacent to one another form a walled trough at interconnections of the plurality of roof panels. A self-propelled automatic welder is positioned and guided within the walled trough to make a weld joint at the walled trough, and thus forming the sealed floating roof.

A frame may comprise a plurality of interlocking tab-and-slot frame members forming a three-dimensional structure. A removable stringer may be designed into one or more of the interlocking tab-and-slot frame members. The stringers may be removed after positioning and welding of tab-and slot frame members together. Notches may also be designed into and formed as additional features of a tab-and-slot frame member. Notches may serve as a guide for bending tab-and-slot frame members and in the creation of tabs and/or slots of the tab-and-slot frame members.

A method of forming a functional razor cartridge for repeated shaving comprises rapid prototyping a housing of a razor cartridge. The housing has a front wall, a rear wall and opposing side walls disposed transverse to and between said front and rear walls. The method further comprises loading a metal insert with one or more elongate blade assemblies and disposing the metal insert in the housing such that the one or more blade assemblies extend between the opposing side walls of the housing.

The disclosure relates to a method of manufacturing a heat exchanger assembly with an enhanced material system. The enhanced material system includes refrigerant tubes extruded from a high purity AA3000 series alloy billet having about 1% by weight (wt %) Mn and pre-braze treated with either a reactive zinc flux or a mixture of elemental zinc powder and a controlled atmosphere brazed (CAB) flux applied by glass plasma or organic binder, such as an organic binder, fins formed from modified a AA3003 alloy having less than 0.05 wt % Cu and from 1.2 to 1.8% wt % Zn, and header manifolds manufactured from a AA3000 series alloy with a AA4000 series cladding having 0.9 to 1.1 wt % Zn. The enhanced material system may also include a post braze coating and a subsequent organic polymer resin topcoat.

An ophthalmic surgical instrument comprises a multi-diameter shaft, a horn fixedly threaded into the shaft, a surgical tip for ophthalmic surgery including a tip end and threadably engaging the horn opposite the shaft, and a plug on the shaft. Weld material holds the plug on the shaft in a selected angular and longitudinal position with an angle-locating recess on the plug's circumference having a predetermined angular clocked relation to a face direction of the tip end. The plug's recess engages an irrigation tube on a subassembled handle with shell and irrigation tube, such that the subassembled handle has a known clocked position relative to the tip end of the tip, thus facilitating use by a surgeon. A related method is also disclosed and claimed.

Methods for manufacturing modular leashes are disclosed. The modular leashes may comprise a flexible portion including a lead end and a handle portion. Manufacturing the flexible portion may comprise heating a pin and securing the pin to a lead end, so as to melt the lead to the pin using ambient heat from the pin. In some embodiments, heating the pin uses induction heating. Manufacturing the flexible portion may further comprise inserting the lead end into a sleeve, and securing the lead to the sleeve by crimping the sleeve onto the lead. Manufacturing the handle portion may comprise inserting handle ends into a first end of a sleeve and inserting a fastener into the handle ends. Manufacturing the handle portion may further comprise inserting a fitting into a second end of the sleeve so that a space between the sleeve and the fitting may receive the handle ends.

The present invention relates to an automobile urea tank and a forming method thereof. The method includes the following steps: 1) producing an upper half casing and a lower half casing through an injection molding method; 2) after the upper half casing and the lower half casing are formed, assembling built-in parts of the upper half casing and the lower half casing; 3) welding the assembled upper half casing and the assembled lower half casing to form a whole; and 4) assembling components on surfaces of the upper half casing and the lower half casing. This method can improve design freedom of built-in elements of the tank body, and can save a lot of raw materials; the structure is simple and firm; moreover, the production efficiency is improved, and the production cycle is shortened.
