摘要:
An aerosol generator for generating an aerosol from a fluid, comprising: a vibratable membrane (22) having a first side (24) for being in contact with the fluid and an opposite second side (25), the membrane having a plurality of through holes (26) penetrating the membrane in an extension direction (E) from the first side to the second side, whereby the fluid passes the through holes from the first side to the second side when the membrane is vibrated for generating the aerosol at the second side, each through hole (26) having along its extension direction (E) a smallest diameter (Ds), a larger diameter (DL) that is larger than the smallest diameter and defined by that diameter that is closest to triple, preferably twice said smallest diameter, each through hole having a nozzle portion (32) defined by that continuous portion of the through hole in the extension direction comprising the smallest diameter of the through hole and bordered by the larger diameter of the through hole, characterized in that the ratio of the total length of each through hole (26) in the extension direction to the length of a respective one of said nozzle portions (32) in the extension direction is at least (4), preferably at least (4.5) and most preferred equal to or larger than (5).

A motor vehicle is provided with a sliding door, which has an inner side facing the vehicle interior, on which a protruding armrest is disposed. The sliding door can be displaced from a closed position in which the entry opening is closed by the sliding door, within the scope of an opening process via an intermediate position in which the sliding door is outwardly offset with respect to an adjoining vehicle wall, into an open position in which the inner side of the sliding door is disposed opposite to the outer side of the vehicle wall. Within the scope of the opening process the protruding armrest can be moved automatically from a usage position into a non-usage position in which the protruding armrest is set back with respect to the usage position in the direction of the inner side of the sliding door.
摘要:
The invention refers to a thermoplastic polyurethane produced from at least an organic diisocyanate and a compound which is reactive toward isocyanates, wherein the polyurethane comprises the ester of a tricarboxylic acid with at least one alcohol and wherein all acid groups of the tricarboxylic acid are esterified with an alcohol. The invention further refers to a process for producing the respective polyurethane, products comprising this thermoplastic polyurethane and the use of the ester of a tricarboxylic acid as plasticizer in thermoplastic polyurethanes.

A printing module for an ink-printing system, interchangeably attached in a holder, consists of an ink storage container with an ink-printing head arranged on it. The ink storage container contains a housing with an assembly surface for an ink-printing head, as well as an ink collection region directly adjacent to the assembly surface. The ink collection region is covered over a large area with a filter element made from woven plastic fabric. Furthermore, a storage element made of a micro-channeled, ink absorbing and releasing material is arranged in the housing, which is in direct contact with the filter element over a large area.

The present invention deals with low temperature impact resistant, easily flowing, thermoplastic polyurethane elastomer compositions, comprising:A) 5-95 parts by weight of at least one thermoplastic polyurethane elastomer (A) having a Shore A hardness less hah 95; andB) 95-5 parts by weight of at least one thermoplastic polyurethane elastomer (B) having a Shore A hardness greater than 98, whereby the parts by weight of (A) and (B) total 100 parts by weight; andC) 0-60 weight percent based on the weight of (A) and (B) of a reinforcing filler.The products are prepared by melting together polyurethane elastomers (A) and (B) at temperatures of from 140.degree.-250.degree. C., preferably in an extruder, and are most preferred for the preparation of ski boots and injection molded articles for motor vehicles.
摘要:
An outer wall element for buildings wherein, between the inner wall shell and a solar-radiation permeable outer wall shell, a solar-radiation permeable and heat-insulating layer is arranged, the latter being separated from an inner heat-insulating layer of the inner wall shell by an interface that absorbs the solar radiation from the outer heat-insulating layer. At least the inner wall shell is provided with marginal lining elements, which can be parts of a frame, panels or the like, extending at least up to the interface and conveying heat to the inner wall side. In order to protect the lining elements from the high temperatures reached in the outer heat-insulating layer because of the use of solar energy, the outer heat-insulating layer and the lining elements are separated from each other by insulating elements with poor heat conductivity, which starting from the lining elements cover the inner heat-insulating layer along a marginal strip in the interface.
摘要:
A pair of conveyor rolls for transporting each record sheet to be printed past the ink-jet printing head is disposed directly below the printing zone of an ink-jet printing head to permit the transportation of freshly printed record sheets within an ink-jet printer without the print being smudged. A gripping device grabs the printed record sheet at its lower edge immediately after it has left the pair of conveyor rolls and carries it out of the printing zone and into an output area.

A printer includes a sheet storage cassette and a sheet separation device for storing and separating individual sheets prior to printing, as well as a sheet deposit device for receiving of the printed-on individual sheets. A sheet storage cassette (2) is formed of two cassette sections (5 and 6), which can be pivoted relative to each other in order to achieve a compact construction of the printer in view of the space requirements of the sheet storage cassette. The first cassette section (5) is fixedly disposed opposite to the sheet separation device (11). The second cassette section (6) is formed as a flap cover (2), pivotally supported at the printer. The flap cover (2) forms the upper side of the printer in the closed state. The flap cover (2) is aligned with the first cassette section (5) in a flipped open state under formation of a sheet storage cassette (4).

Aerosol generator having a liquid reservoir (10) defining in a sealed state a volume VR configured to hold an initial volume of liquid VL; a membrane (5) having openings, the liquid reservoir (10) being connected to the membrane (5) to feed the liquid to one side of the membrane, the membrane being oscillatable to transport the liquid through the openings whereby the liquid is emitted in the form of an aerosol on the other side of the membrane, wherein the volume VR of the liquid reservoir (10) before the membrane (5) is oscillated is configured to contain more than 5 ml of gas at an initial volume of the liquid VL of at least 5 ml.
摘要:
A method for fashioning ink channels in a write head for a dot-matrix ink printer means, whereby form needles respectively coated by parting agent and cylindrically surrounded by piezo electric drive elements are aligned in a casting mold in accord with the desired course of the ink channels to be fashioned, are cast out with a casting compound and, after the curing of the latter, are removed upon formation of the respective ink channels partially surrounded by the allocated piezo electric drive elements, and isolation of the drive elements from a writing fluid in the ink channels is achieved in a way that is simple in terms of production engineering. An envelope coat is applied to the form needles coated with parting agent, being applied thereto before they are introduced into the casting mold, this envelope layer forming the inside channel wall of the appertaining ink channel after the removal of the form needles and of the parting agent. The new method serves the purpose of manufacturing ink printer heads that work based on the principle of individual drop ejection (drop on demand).
