摘要:
The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles, iron ore piles, and also for piles within and/or being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.

Die Erfindung betrifft eine neuartige Oberflächenbeschichtung für hochwertige Weiß-Grau-Ware, also Gegenstände des Haushalts-, Sanitär- und/oder Automotive-Bereichs, insbesondere Gehäuseelemente von entsprechenden Apparaturen und Maschinen sowie Dekor, beispielsweise solche, die gezielt metallische Applikationen und/oder Elemente haben. Durch die vorliegende Erfindung wird erstmals ein Zusammenhang zwischen einer Oberflächenstrukturierung und der Oberflächenbeschichtung einer edlen metallischen oder metallisierten Oberfläche hergestellt, derart, dass die Höhe Oberflächenrauigkeit der Oberflächenstrukturierung die Dicke der Oberflächenbeschichtung um ein Vielfaches überragt, damit die Oberflächenstrukturierung auf eine Art intrinsischen Kapillar-/ Kanaleffekt ein Verfließen unerwünschter Rückstände begünstigt. Durch das Verfließen wird die Kontur der Verschmutzung verwischt bis sie schließlich gänzlich unkennbar wird.
摘要:
An excess sprayed coating removal device for removing excess sprayed coatings adhering to the inner surface of a crank chamber of a multi-cylinder engine includes: a rotatable nozzle that is inserted in a first small chamber, movable in a direction parallel to the axial direction of a cylinder bore communicating with the first small chamber, and jets high-pressure water toward the leading end side thereof; and at least a single of shields that are each inserted into a second small chamber adjacent to the first small chamber so as to face into a communication hole, the shields each protecting from the high-pressure water a sprayed coating sprayed on the inner surface of the cylinder bore communicating with the second small chamber. The shields each have a block portion in a region facing into the communication hole, the block portion configured to shut the high-pressure water that is jetted from the nozzle and passes through the communication hole.
摘要:
The invention relates to a device for blowing a gaseous or liquid medium at individual pieces of a material flow that are conveyed over a free-fall path or a link conveyor, comprising a housing (12) having at least one connection opening (1) for the gaseous or liquid medium, and a plurality of blowing nozzles (7), by means of which the gaseous or liquid medium is blown at predetermined individual pieces of the material flow in a controlled manner, and valves, preferably solenoid valves (3), which are associated with the blowing nozzles (7) and by means of which the blowing process can be triggered and/or stopped and which are arranged on or at least partially in the housing, and a flow channel (4) between each blowing nozzle (7) and the valve seat of the valve (3) associated with the blowing nozzle (7). In order to reduce the suction of dust into the flow channel (4) after the valve has been switched off, at least one respective connecting channel (5) branches off from each of a plurality of flow channels (4), which connecting channel opens into at least one pressure reservoir (6), which is common to the connecting channels (5) and is or can be closed in a gas-tight or liquid-tight manner with the exception of the connecting channels (5).
摘要:
A synergistic composition comprising a THP salt and a biopenetrant, in which the biopenetrant comprises a polymer of an unsaturated carboxylic acid or a copolymer of an unsaturated carboxylic acid with a sulphonic acid, said polymer or copolymer being terminated by a mono- or diphosphonated unsaturated carboxylic acid group or having such monomers incorporated into the polymer backbone. This composition acts synergistically to enhance the biocidal efficacy of the THP salt against both planktonic (free-swimming) and sessile (attached) bacteria, and also acts synergistically to enhance the efficacy of the THP salt in the dissolution of iron sulphide scale.
摘要:
Es wird eine Befeuchtungsvorrichtung zum Befeuchten von rieselfähigem Gut, insbesondere Mehl, mit einem Rotor (2), der eine Rotationsachse aufweist und zumindest teilweise von einer Umhüllung (4) umgeben ist, mit einer Rieselgutzufuhr in die Umhüllung und einer Flüssigkeitsausgabe, die Flüssigkeit vom Rotor aus radial nach außen ausgibt, angegeben. Man möchte eine funktionsfähige Vorrichtung zum Befeuchten von rieselfähigem Gut bereitstellen. Hierzu ist vorgesehen, dass der Rotor (2) mehrere vom Umfang des Rotors (2) abstehende Flächen (7) aufweist, die mit einer Umfangsrichtung des Rotors einen spitzen Winkel einschließen, von denen jede an einem Flächenträger (9) angeordnet ist, wobei zwischen benachbarten Flächenträgern (9) jeweils eine Lücke vorgesehen ist, die zur Flüssigkeitsausgabe hin eine Verengung aufweist.
