A method of resistance spot welding a steel workpiece to an aluminum or aluminum alloy workpiece is disclosed. One step of the disclosed method involves providing a workpiece stack-up that includes a steel workpiece and an aluminum workpiece. Another step involves preheating the welding electrode that is meant to contact the aluminum or aluminum alloy workpiece. Yet another step of the disclosed method involves pressing the preheated welding electrode and another welding electrode against opposite sides of the workpiece stack-up, with the preheated welding electrode abutting the aluminum or aluminum alloy workpiece, and passing an electrical current between the two welding electrodes at a weld site to initiate and grow a molten weld pool within the aluminum or aluminum alloy workpiece.

A heat exchanger is provided that includes plate pairs stacked one above the other. A first flow chamber is formed between the two plates of a plate pair by conducting a first fluid therethrough, a second flow chamber for conducting a second fluid therethrough, wherein the second flow chamber is formed between two adjacent plate pairs, an inlet opening for introducing the first fluid, and an outlet opening for discharging the first fluid. The plates have at least one expansion opening, in particular at least one expansion slit, for reducing stress in the plates. The heat exchanger can withstand high thermal and mechanical loads even over a long time period, such as 10 years.

A magnesium modified Y-type molecular sieve has a rare earth oxide content of about 4% to about 11% by weight, a magnesium oxide content of about 0.1% to about 4% by weight, a sodium oxide content of about 0.3% to about 0.8% by weight, a total pore volume of about 0.33 mL/g to about 0.39 mL/g, a percentage of the pore volume of secondary pores having a pore size of 2-100 nm to the total pore volume of the modified Y-type molecular sieve of about 10% to about 30%, a lattice constant of about 2.440 nm to about 2.455 nm, a percentage of non-framework aluminum content to the total aluminum content of the modified Y-type molecular sieve of no more than about 20%, and a lattice collapse temperature of not lower than about 1045° C.

An ignition laser is provided for an internal combustion engine, in which the combustion chamber window is connected to a housing of the ignition laser in a gas-resistant, pressure-resistant, and temperature-resistant manner. Furthermore, a pressure relief bore is present which effectively prevents a pressure increase in the housing of the ignition laser.

This invention relates to the use of pore mouth control of microporous solids for developing novel molecular sieve adsorbents and their potential in the drying of alcohols. More specifically, the invention relates to the manufacture and use of a molecular sieve adsorbent, which selectively adsorbs water from azeotropic alcohol-water mixtures by pore mouth control of microporous solids with liquid phase metal alkoxide deposition on the external surface at ambient conditions of temperature and pressure. The prepared adsorbent is therefore useful for the commercial drying of alcohols.

The invention relates to a strip or foil (1) made from aluminium or an aluminium alloy that has an external oxide layer. The object of providing a strip or foil made from aluminium or an aluminium alloy in which the thermal and/or electrical conductivity remains consistently high regardless of the formation of an aluminium oxide layer is solved by arranging thermally and/or electrically highly conductive functional particles on one or both sides of the strip or foil, which functional particles at least partly penetrate the oxide layer of on the strip or foil.

A seal segment for a gas turbine engine has a radially outer wall with a first length, a radially inner wall with a second length, and a rib member which extends radially between the outer wall and the inner wall and along the first and second lengths.

The present invention provides an illumination apparatus. The illumination apparatus comprises a body having a lower portion coupled to a standard metallic lamp adaptor and an upper portion; a light source module comprising an LED array of LED chips connected in series, a phosphor powder layer encapsulating the LED chips, and a pair of conductive wires electrically connected to the LED chips for transmitting electric power to the LED chips; and a transparent housing coupled to the upper portion of the body, so that the LED chips are enveloped within the transparent housing.

An embossing apparatus, similar to those used in the paper industry, for use in the leather industry to emboss leather and leather type textiles. The apparatus includes a rotating felt under tension. In a preferred embodiment, the felt wraps around a heated embossing cylinder under tension and there is no nip. In this case, the leather textile is conveyed while sandwiched between the felt and the cylinder and is thereby embossed.

A method of manufacturing a cellulose-based shaped article. The method comprises subjecting a solution of lignocellulosic material, dissolved in a distillable ionic liquid, to a spinning method, wherein the ionic liquid is a diazabicyclononene (DBN)-based ionic liquid. DBN-based ionic liquids have good dissolution power, high thermal and chemical stability, lack runaway reactions and exhibit low energy consumption, due to low spinning temperatures. The shaped cellulose articles can be used as textile fibres, high-end non-woven fibres, technical fibres, films for packaging, and barriers films in batteries, as membranes and as carbon-fibre precursors.

A manufacturing of wires with optimized insulation properties, providing an insulating wire and the wire drawing process for producing it. The wire enamel has three layers: base layer (2), middle layer (3) and top layer (4), wherein these layers wrap around the conducting wire (1) in this order. The wire drawing process is carried out by a) Primary drawing; b) Final drawing and c) Enameling process carried out in line, wherein the enameling is conducted preferably with a specific number of dies for each layer. The process and composition conditions of the wire allowed to provide a triple layer wire that presents high resistance to partial discharges, high thermal class and high resistance to abrasion, thus, increasing the service lifetime of the wire in demanding motor applications when high thermal, high mechanical and high electrical resistance are required.
