摘要:
An improvement in cement used for mass concrete, high-strength concrete, high-fluidity concrete, noncontractive concrete and high-durability concrete in the fields of civil engineering and construction, and for building materials manufactured by extrusion molding and sheet making. When the ratio of A12O3 to Fe2O3 in the cement clinker is regulated to a value of 0.05-0.62, the strength of high-strength and high-fluidity concrete can be further improved, and the heat of hydration can be minimized as the fluidity improving performance and long term strength of the cement are maintained.

摘要:
Bei einem Axialkompressor für ein Gasturbinentriebwerk umfasst die Rotortrommel (2) in den thermisch weniger belasteten ersten Kompressorstufen (3 bis 6) einen einstückig geformten Ring oder aneinander gefügte Rotorringe (7 bis 10) mit auf diese nahe den Rotorschaufeln aufgewickelten Fasergurten (18, 21), die aus in eine hochtemperaturbeständige Polymermatrix eingebetteten Kohlefasern bestehen. Aufgrund der nicht notwendigen Rotorscheiben, deren Funktion die Fasergurten übernehmen, hat der Kompressor ein geringes Gewicht und einen geringen Platzbedarf und kann zudem kostengünstig gefertigt werden.
摘要:
A mixer capable of developing suitable stirring characteristics by forming a sufficient vertical circulation flow over the entire part of the inside of a tank, wherein an opening (4) is formed in a stirring blade (3) under the following conditions: (i) the ratio of the opening area of the opening (4) in the upper half (U) of the stirring blade (3) to the overall area of the upper part (U) of the stirring blade (3) (the opening rate in the upper half (U) of the stirring blade (3)) is 45 to 80%, (ii) the ratio of the opening area of the opening (4) in the lower half (D) of the stirring blade to the overall area of the lower half (D) of the stirring blade (3) (the opening rate in the lower half (D) of the stirring blade (3)) is 18 to 50%, and (iii) the ratio of the opening rate in the lower half (D) of the stirring blade (3) to the opening rate in the upper half (U) of the stirring blade (3) is 31 to 71%.
摘要:
A power transmission belt (10) having a body (22) with an inside, an outside, and laterally oppositely facing side surfaces. The body (22) has at least one surface that engages a pulley to frictionally transmit forces between the power transmission belt and pulley. The body (22) includes rubber defining at least a part of the at least one surface. The rubber is a composition made up of a blend of at least: a) 100 parts by weight of an ethylene/a-olefin elastomer; b) 10 to 25 parts by weight of a plasticizer having a solubility parameter of from 8.3 to 10.7 (cal/cm 3 ) 1/2 ; and c) 60 to 110 parts by weight of an inorganic filler.
摘要:
The invention relates to a compressed air foam producer, wherein a fire or decontamination specific additive is injected directly into the foam forming flow supplied to the main water flow and/or the main water flow. A mixing pump for the foaming agent draws off an auxiliary and motive water flow, wherein initially the additive and then the foaming agent is injected. The foaming agent-additive-water mixture, which is produced directly on site, is mixed well together and with the main water flow ensuring a fine, uniform distribution of the additives in the compressed air foam. The thus produced compressed air foam ensures optimal, economical and environmentally friendly fire-fighting and decontamination.

The invention relates to the use of a transdermal therapeutic system (TTS) comprising a medicinal layer, which contains at least one matrix comprising an active ingredient and /or an active ingredient reservoir and a diffusion barrier situated on the skin side of the active ingredient reservoir and permeable to active ingredients, in addition to, an ergoline-derivative or physiologically compatible salt with an acid thereof, as an active ingredient, for producing a means for treating the restless-legs-syndrome.
摘要:
In einem elektronischen Regelsystem sind für verschiedene Triebwerksleistungsstufen zur Einstellung einer jeweils maximalen Triebwerksleistung mit Bezug auf die Flughöhe (ALT), die Außentemperatur (DTAMB) und die Flugmachzahl (MN) dreidimensionale Datensätze (Datenkuben L11-L14) jeweils für verschiedene leistungsbegrenzende Triebwerksparameter gespeichert, um eine jedem Parameter entsprechende maximale Leistung separat zu berechnen. Für die Leistungsreduzierung aufgrund Luftentnahme sind entsprechende separate Datenkuben (L21-L24) gespeichert. In einem Vergleicher wird der jeweils kleinste Wert unter Abzug der Leistungsreduzierung ermittelt und danach die Kraftstoffzufuhr zur Leistungsregelung eingestellt. Bei übereinstimmenden Randbedingungen können gleiche Datenkuben (L24) für unterschiedliche Triebwerksleistungsstufen gespeichert sein. Das System benötigt eine geringe Speicherkapazität und einen niedrigen Rechenaufwand.
