Continuous autodeposition from a bath having a low solids concentration and stable coating characteristics is achieved by close control of bath iron concentration, preferably by maintaining iron concentration below about 1.5 gm/l by controlled discard and replacement of bath volume.

A road-haulage semi-trailer having a sliding king-pin for lifting the landing legs to the retracted position, the landing legs being spring-biassed towards the retracted position and coupled to the king-pin through a rack and pinion to give rapid lifting of the legs with a small king-pin movement. The king-pin is disengageable to move independently of the landing legs over a large distance between front and rear clamps which enable it to be locked in either a front or a rear position for travell...

A method for salt bath-nitriding a metal member having a blind hole, which comprises supporting the metal member so that the open side of the blind hole is directed upward, filling a salt bath-nitriding agent into the blind hole and immersing the resultant metal member in a salt bath melt.

The present invention discloses improved methods of disaggregating protein aggregates, and refolding denatured proteins, using high pressure. In particular, the present invention provides for the use of agitation, high temperature, "stepped" depressurization, dialysis and dilution under pressure to increase the speed and extent of aggregate dissolution and protein refolding.

A process for the preparation of a catalyst comprises abrading a solid metallic material selected from platinum, palladium, platinum-palladium alloys and mixtures thereof, in the presence of an aqueous alumina suspension to obtain a suspension which contains finely divided particles of the metallic material and the alumina uniformly dispersed throughout, applying the thus obtained suspension to a support, and then removing the water therefrom to obtain the desired catalyst.

The present invention is directed to a method of refining spangle facet size in a hot-dip coated product by applying grain-refining particles to the surface of a steel substrate before immersion into the hot-dip coating bath, to an intermediate coated steel sheet, and to a finish coated steel sheet having a different coating spangle facet size on opposite surfaces.

A method of reducing oxide thickness variations in a STI pattern that includes both a dense trench array and a wide trench is described. A first HDP CVD step with a deposition/sputter (D/S) ratio of 9.5 is used to deposit a dielectric layer with a thickness that is 120 to 130% of the shallow trench depth. An etch back is performed in the same CVD chamber with NF.sub.3, SiF.sub.4 or NF.sub.3 and SiF.sub.4 to remove about 40 to 50% of the initial dielectric layer. A second HDP CVD step with a D/S ...

An indicator to indicate an amount of power available from an energy storage device. The indicator normalizes raw power values to values which are understood by the driver. The indicator indicates the normalized values to facilitate making a driving decision.

Methods of forming trench isolations are provided. A method includes providing a semiconductor substrate having a cell array region and a peripheral region. At least one cell trench in the cell array region and at least one peripheral trench wider than the cell trench in the peripheral region of the substrate are formed. The cell and the peripheral trenches have sidewalls. A first dielectric layer that partially fills the cell and peripheral trenches is formed over the substrate. At least one ph...

The present disclosure provides an effective method for the refolding of denatured proteins in solution so that properly folded, biologically active protein in solution is recovered in high yield. The refolding takes place at pressures between about 0.25 kbar to about 3.5 kbar, advantageously at about 1.5 kbar to about 3 kbar. Typically a chaotropic agent is present at a concentration which is not effective for denaturing protein at atmospheric pressure, and optionally, oxidation-reduction reage...
