Patent EP-0168215-A2 (EP)
Inventor: OTHEN DAVID GEORGE THE BRITISH
IPC: C09D5/08

Abstract: A process for producing corrosion inhibiting particles comprising binding corrosion inhibiting anions to particles of an inorganic oxide by ion-exchange to form anion-exchanged particles, the anions of which are releasible by further ion-exchange in which the inorganic oxide particles having surface hydroxyl groups are first contacted with an acidic solution containing labile anions at a pH sufficiency below 7 for the protons of the hydroxyl groups to be replaced by the labile anions and thereafter contacting the particles of the labile anion-exchanged inorganic oxide with a solution containing the required corrosion inhibiting anions so that the labile anions are replaced by the corrosion inhibiting anions. The labile anions are anions of water soluble, acid compounds which have a lower affinity for the oxide surface than the required corrosion inhibiting anions and which form a soluble salt with the cation of the compound providing the corrosion inhibiting anions. The process facilitates the use of corrosion inhibiting anions which are sensitive to low pH in the preparation of corrosion inhibiting particles. In particular the process is useful for producing molybdate exchange inorganic oxide particles.

Abstract: The present invention relates to novel electrostatic charge transfer media and a method for preparing said media. 
     In electrophotography or electrostatic printing, the prior art techniques for accomplishing charge transfer from one surface to another involves either: (1) conduction of electric charges across an air gap, or (2) direct charge transfer if the air gap is eliminated. While the air breakdown charge transfer technique is simple, it does not provide high resolution [less than 80 line pairs per millimeter (1 p/mm) can be achieved] or continuous tone gray scale reproduction. The presently known techniques for direct charge transfer require a very smooth surface, a transfer liquid interfacing the donor and receptor films, very high pressures to eliminate the air gap, or a surface provided with a multitude of conductivity sites. However, most direct charge transfer techniques are too slow for many commercial applications, e.g. duplication of customers' checks by banks. 
     This invention involves an article having improved electrostatic charge transfer properties. The improvement in charge transfer properties results from subjecting a layer of photoconductive-insulative material or dielectric material on the charge donor or a layer of dielectric material on the charge receptor, or both layers, to plasma treatment process to provide an oxygen-enriched surface to the photoconductive-insulative layer and/or the dielectric layer. 
     The articles of this invention provide transfer of charge with high efficiency, high resolution, and at much higher speeds than has previously been possible.

Abstract: Using conventional methods it is not possible to dye wool at below 80 DEG C with reactive dyes in medium and deep shades so that the resulting dyeings have satisfactory fastness properties. However, to make such a dyeing process available even for use in domestic washing machines it must be possible to dye at even lower temperatures. It has now been found that standard wool fibre material can be dyed level and fast with reactive dyes at between 55 and 70 DEG C by adding from 4 to 10% of an inorganic or organic acid, i.e. at pH 1.8-3.5, preferably pH 2.4-3.

Abstract: An energy-absorbing element (51) is provided between an insulative piston (52) and a movable contact (28) of a switch (22) for a high-voltage device (12). In arrangements where a fusible element (18) is in electrical shunt with the switch, the energy-absorbing element improves the rapid commutation of the current from the switch to the fusible element where final circuit interruption takes place. The switch is of the general type in which ignition of a power cartridge (32) moves the insulative piston, which is normally located in a bore (30) formed in a conductive member (24), away therefrom and into a passageway (44) formed in an insulative liner (46). The movement of the piston moves the movable contact through the passageway and away from the conductive member to break an electrical interconnection (via 50) between the conductive member and the movable contact. This forms a gap between the conductive member and the movable contact and opens the switch. The ignition of the power cartridge evolves high pressure within a chamber defined by the piston and the bore. This high pressure acts against the piston and the resulting forces rapidly drive the piston; the movable contact being driven via the transmission of forces through the energy-absorbing element. The energy-absorbing element enhances the rapid and simultaneous movement of the piston and the movable contact. The energy-absorbing element absorbs sufficient energy at the interface between the piston and the movable contact to prevent undesirable reaction effects which may be caused by the reaction or rebounding forces between the piston and the movable contact.

Abstract: A method is provided for making a semiconductor structure which includes the steps of forming in a semiconductor body a P/N junction and a first opening (50, 54) in a first insulating layer (42) disposed on the surface of the semi­conductor body. A trench (22) is then formed in the semicon­ductor body having a sidewall located along a given plane through the opening and through the P/N junction. A second layer of insulation (56) is formed within the opening and on the sidewall of the trench. An insulating material (24) is disposed within the trench (22) and over the second insulat­ing layer (56) in the opening and a block (62) or segment of material is located over the trench (22) so as to extend a given distance from the trench over the upper surface of the body. The insulating material (24) and the block (62) are then etched so as to remove the block and the insulating material along the sides of the block. The exposed portions of the second insulating layer (56) are now etched to form a second opening therein within the first opening (50, 54) in the first insulating layer (42). A layer (64) of low viscosity material, such as a photoresist, is formed over the semicon­ductor body so as to cover the remaining portion of the insulating material (24), the layer (64) of low viscosity material and the insulating material (24) having similar etch rates. The layer (64) of low viscosity material and the insulating material (24) are then simultaneously etched directionally, e.g., by a reactive ion etching process (RIE),   until all of the layer (64) of low viscosity material is removed to at least the surface of the second insulating layer (56) at the trench (22). Any suitable wet etchant may then be used, if desired, to remove any remaining low viscosity material disposed within the second opening in the second insulating layer. Metallic contacts (W T , W B , B O ) may now be formed, e.g., by evaporation, on the surface of the semiconductor body within the second opening in the second insulating layer without the concern that the metallic material will seep or enter into the trench causing a short at the P/N junction. 
     In a preferred embodiment of the invention, the insulating material (24) is polyimide and the block (62) of material, as well as the layer (64) of low viscosity material, is made of photoresist.

Abstract: An ultra-high pressure hose assembly capable of withstanding sustained internal fluid pressures exceeding 413.7 MPa (60,000 psi) comprises an innermost tubular core (12), a plurality of successive tubular layers (L) and an outer containment sleeve (14). The innermost tubular core (12) and containment sleeve (14) are designed to add substantially no structural integrity to the overall assembly but rather function only as a fluid barrier and containment means for the tubular layers respectively. The tubular layers (L) serve as structural members of the overall assembly and respectively comprise individual bands which are alternately helically wound clockwise and anti-clockwise around and directly agains the layers immediately below them at predetermined helix angles. Each band in turn comprises a number of separate steel wires which have opposing flat sides and which are positioned in unconnected edge to edge relationship to one another so as to form the band. In addition, the bands of successive layers, starting with the innermost tubular layer, define successively increasing helix angles, thereby to cause all of the layers to share substantially in the overall loading of the assembly at its operating pressure.
