Abstract:
The invention relates to a method for cold gas spraying in which a spray powder containing photocatalytically active spray particles is accelerated by means of a carrier gas in a nozzle and forms a coating upon striking a substrate. According to the invention, the method is characterized in that at least one part of the photocatalytically active spray particles consists of nanocrystalline agglomerates having a porosity of 200 to 800 m2/g, the porosity being determined by means of a BHT measurement with nitrogen. Coatings produced with the method according to the invention and objects having such a coating are also claimed.
Abstract:
A memory retention and support system includes a memory chassis. A board is mounted to the memory chassis. A memory connector is mounted to the board and includes a pair of guide members at opposite distal ends of the memory connector and a pair of opposing outer walls extending between the guide members. A connector reinforcing member engages the memory connector to urge the guide members toward each other and to urge the opposing outer walls toward each other. A damping member is operable to be positioned adjacent to and spaced apart from the memory connector in order to engage a memory module when the memory module is coupled to the memory connector. The connector reinforcing member and the damping member act to resist a discontinuities between a plurality of memory contacts on the memory module and a plurality of connector contacts on the memory connector.
Abstract:
A method for arc spraying in which at least one wire-shaped spray filler material is melted in an arc by means of electric current and atomised by means of an atomising gas flow and applied in the form of a particle stream onto a workpiece, at least one wire-shaped spray filler material being preheated before the melting in the arc.
Abstract:
A method for producing a pipe, a carrier element being coated by means of a thermal spraying method, the material of the pipe formed later being selected as the coating material, and the coating forming the pipe being detached from the carrier element, the spraying angle, at which the coating material is sprayed onto the carrier element, being selected such that a low level of adhesion of the coating on the carrier element is achieved.

Abstract:
The invention relates to a storage tank for storing a sorbent material. Said storage tank comprises a pressure vessel, a connecting element to an external supply system, at least on sorbent material which contains a sorbent and an adsorbate that adsorbs thereto, especially a gaseous fuel, preferably hydrogen, and which is stored in the storage tank at least during proper use of the storage tank, and a conduit for feeding and/or discharging sorbent material into/from the storage tank. At least one second duct is provided for supplying and/or evacuating a gas (gas duct). The sorbent is formed on the basis of heavy-duty adsorbents based on activated carbon in the form of discrete, activated carbon grains, preferably spherical ones. At least 70 percent of the entire pore volume of the heavy-duty adsorbents are formed by microspores having a diameter of ≦20.
Abstract:
An integrated circuit, comprises a wakeup terminal; a supply voltage terminal configured to receive a supply voltage; and a power control circuit. The power circuit comprises an enable circuit coupled to the wakeup terminal and configured to generate a voltage monitoring enable signal as a response to a wakeup signal received at the wakeup terminal, and a voltage monitoring circuit for generating a supply voltage level indication signal. The voltage monitoring circuit is coupled to the supply voltage terminal and comprises an operation switch controlled by the voltage monitoring enable signal. The voltage monitoring circuit is configured to determine if the supply voltage is above a threshold voltage and set the supply voltage level indication signal accordingly. The integrated circuit further comprises processing circuitry, with the supply voltage level indication signal controlling the switching between a normal operation state and a standby state of the processing circuitry.
Abstract:
The invention relates to an adsorption filter material (1) that provides protection against chemical toxins, chemical weapons and pollutants, with a preferably multi-layer composite construction (2). The layer construction (2) includes at least one planar support layer (3) with two opposing sides (3′, 3″) and an adsorption layer (4), provided on the support layer (3) made from a material which adsorbs chemical toxins, the surface of at least one of the both sides (3′ and/or 3″) of the support layer (3) being modified by plasma treatment. The surface properties, in particular the surface finish and the surface reactivity can be adjusted and optimised to match the application by means of the plasma treatment.
Abstract:
A cooling element for shaft furnaces includes an area through which coolant flows as a result of the arrangement of at least one internal coolant-carrying channel, which leads to coolant feed and discharge pipes connected to the cooling element. At the end of the element where coolant enters and/or exits, the coolant-carrying channel extends beyond the opening of the pipe and into an edge area of the cooling element. The coolant carrying channel has a cross-section which is larger than the cross-section of the internal channel, wherein the coolant section is provided with a guide element which divides the channel lengthwise in the flow direction so that the coolant is guided to the edge area of the cooling element and then back again in the opposite direction.
Abstract:
The present invention relates to a textile sheetlike structure (1), in particular for protection against biological and chemical noxiants and poisons, such as biological and chemical warfare agents, said sheetlike structure (1) having a textile support layer (2) and a first sheetlike piece (3) of activated carbon fibres which is laminated onto the support layer (2), wherein the sheetlike structure (1) further comprises a second sheetlike piece (4) of activated carbon fibres which is laminated onto the support layer (2) such that edges of the two sheetlike pieces (3, 4) touch and/or overlap and wherein the two sheetlike pieces (3, 4) are joined together by the support layer (2). This provides a seamless joining together of two or more sheetlike pieces of activated carbon fibres to form a broadened, continuous sheetlike structure of activated carbon fibres to provide improved making-up utilization of the resulting material in the production of protective materials (such as for example protective suits, protective gloves, protective footwear, protective clothing items, etc).
