Abstract: A welding torch includes a contact tip and a wire electrode guide extending distal of the contact tip. The wire electrode guide includes a metallic outer sheath and a plurality of ring-shaped electrical insulators stacked axially within the metallic outer sheath so as to form a central wire electrode receiving bore through the plurality of ring-shaped electrical insulators.

Abstract: A flow-through sampling apparatus for sampling a bulk solid mixture includes a main body forming an opening. A screen is located in the opening and forms a plurality of sample zones within the main body. The apparatus further includes a first slide door that is movable above the screen so as to close one side of the opening. Further, the apparatus includes a second slide door that is movable below the screen so as to close the other side of the opening.

Abstract: The present disclosure provides processes and apparatus for the production of materials requiring a plurality of chemical reaction steps. In the prior art the number of reaction vessels is minimized by performing two or more reactions together in the same vessel. Instead each process is separated into separate successive steps, in each of which at least two principal components are reacted together, with or without at least one catalyst. In each step the components are reacted under optimum condition for that reaction, using motion-augmented, sub-Kolmogoroff, micro-agitation provided by a separate discrete motor-operated, micro-agitation means. Such means are much smaller in size, but are extremely flexible as to the flow rate and reaction conditions, so that they can be adjusted to suit the reaction, without compromises dictated by attempting to perform other reactions in the same vessel.

Abstract: A process for performing a chemical reaction between a plurality of chemical reactants in the presence of a catalyst, with at least a first reactant in a liquid phase and at least a second reactant in a gas phase, the first and second reactants mixing at least by interdiffusion. The process comprises supplying the reactants to a passage defined by a first surface and a second surface and optionally moving at least one of the first surface and second surface relative to each other. The reactants their mixture or reaction products form respective boundary layers against the first and second surfaces and the radial spacing between the first surface and second surface is equal to or less than the back-to-back radial thicknesses of the boundary layers.
