A low-viscosity dental material contains a non-settling nanoscale filler. Improvements of the mechanical properties of the dental materials, including the abrasive resistance and the compressive strength are provided. Furthermore, the dental materials have increased resistance to microleakage and have increased bond strengths. The filler forms a stable sol with low-viscosity dental materials and t...

A transparent pane arrangement with a prescribed installation alignment comprises at least one transparent substrate and at least two mutually spaced layers made from a material with variable transmission properties for visible light and/or thermal radiation. Both layers respectively have strips which are arranged parallel to one another and are made from the material with variable transmission pr...

A method of producing material in the form of a material web (4) that has discrete pieces of material (6) mounted thereon without the using of an adhesive agent and while using only one single anvil roll, and an arrangement (10) for carrying out the method and comprising an anvil roll (2) which rotates about its longitudinal axis and which is intended to be partially embraced by or be tangential t...

An aqueous liquid multiphase surfactant-containing cleaner having at least two continuous phases, which has at least one lower aqueous phase I and an upper aqueous phase II which is immiscible with the first phase and which can be temporarily converted into an emulsion by shaking, which comprises at least one acid and, in the form of the temporary emulsion, has a pH of less than 7, can be used for...

A multi-layer tubing for use in fluid transport applications. The tubing is suitable for conveying fluids containing hydrocarbons. The tubing comprising an extrudable adhesive layer coextruded around a permeation-resistant layer of fluoropolymer and a layer of polymer chemically dissimilar from fluoropolymer coextruded around the adhesive . The adhesive layer is formed of a polymer blend or alloy ...

A method and apparatus for removing drill cuttings from an oil and gas well drilling platform provides for the separation of drill cuttings from at least a volume of the well drilling fluid (i.e. drilling mud) on the drilling platform so that the drilling fluids can be recycled into the well bore. The cuttings are then transferred to a cuttings collection receptacle (eg. trough) on the platform. T...

A binary two phase engine oil composition having two substantially immiscible liquid phases exhibits improved fuel economy which is maintained over an extended period. The first liquid phase comprises a base oil, natural or synthetic. The second liquid phase is a polar organic liquid, preferably a complex alcohol ester, preferably derived from a polyol, a polybasic acid, and a monohydric alcohol.

The support surface (2) for the ring bearing (4) is provided with a peripheral groove (6) for delivering oil under pressure to the gap between the support surface and bearing. This groove is located near the end of the support surface that first comes into contact with the bearing as it is mounted on the axle (1). The bearing is slid axially along the axle until it abuts against a seal inside the ...

The device for separation of material pieces of electrically conductive material (1) from a mixture of such pieces and those non-conductive (1') has a separation channel (5), which has a V-shaped cross-section, whose V legs are formed by two separated electrically conductive parts (6), forming part of an electrical circuit. A transport device (3) feeds forward the two kinds of material pieces in ...

The shoe has a skate blade or wheel frame attached to the underside, and this is pivotably secured to a bogie. When the blade or wheel frame is in contact with the ground the shoe is supported above the bogie by a height adjustable screw.

An appliance is provided with a feedback system which audibly signals both the activation of user input controls and when the appliance reaches a certain operational stage. The system functions to adjust both of the feedback signals upon a single setting change made by a user, preferably at varying volume rates. In the preferred embodiment, the volume level for the operational stage signal is adju...

The invention relates to a system for the purification of diesel engine exhaust gases, the system being maintenance-free and comprising a first honeycomb catalyst (3) and a second honeycomb catalyst (5) fitted downstream of the first honeycomb catalyst in the flow direction of the exhaust gases, both of which honeycombs (3, 5) contain a catalyst material active for the selective reduction of nitro...

A method and apparatus for dispensing blended fertilizer to a customer at a dispensing site, which may be remote and unmanned, is disclosed. The fertilizer dealer enters the blend of standard fertilizer ingredients required to provide the customer's desired nutrients into a database identified with the customer. The customer identifies himself to a dispensing site based computer which recognizes t...

A method of producing products made of plastics material based on a polymer selected from an ethylene vinyl carboxylate (EVC), polyethylene, an ethylene copolymer, or a mixture of polyethylene and ethylene copolymers is described and comprises a step for the production of a non-cross-linked semi-finished product by injection and moulding and a step for the exposure of the semi-finished product to ...
