摘要:
A transmission includes an input shaft (IP), an output shaft (OP), a single planetary gearset (SP), a compound planetary gearset (CP), shifting elements. The single planetary gearset is arranged before the compound planetary gearset, and the shifting elements comprise at least two brakes (B1,B2), the first clutch (C1), the second clutch (C2), the third clutch (C3), and all the shifting elements are positioned between the single planetary gearset and the compound planetary gearset, which has compact arrangements, and can reduce the power transmission length. The transmission also includes an one-way clutch (OWC) acted on the compound planetary gearset. When the transmission shifts to the first speed stage, the first clutch (C1) and the one-way clutch are operated, and the power is transferred from the input shaft to the output shaft via the single planetary gearset and the compound planetary gearset, and when the first speed stage is shifted to the second speed stage, only the first brake (B1) should be operated to engage, thereby it can reduce the frequency of operating the shifting elements and the shifting time in low speed stage.
摘要:
An interior panelling part for covering an airbag has a sheet-like support, a decorative layer and an intermediate layer arranged between the support and the decorative layer. A passage opening for the airbag is left open in the support. The intermediate layer comprises a mat which spans the passage opening and overlaps with the support outside the passage opening. The intermediate layer and/or the decorative layer is/are weakened longitudinally or offset parallel to an edge of the passage opening on just one side of the passage opening.

A test system and method for performing DSL assessments of a telephone line along a prescribed test path is disclosed. The disclosed test system and method includes a loop diagnostic test unit adapted for testing said telephone line using narrow-band and mid-band frequency test signals; a test system controller and a test system server to provide the DSL assessments to a user via an appropriate interface. In addition, the disclosed analysis methods utilize primary line condition information, secondary line condition information, historical line information, together with real-time measurements and external data inputs to perform line imbalance analysis, fault identification analysis, trend analysis, and jurisdictional analysis all of which have relevance to quality, performance and assurance of DSL service through the telephone line.

The invention relates to an optics changer for arranging an optical element in a target position in a changer chamber of an optical device accessible from the outside via a insertion channel, including a base frame and the optical element that is pivotally fastened to the base frame via a swivel mechanism, wherein the swivel mechanism effects a pivoting movement of the optical element when the optics changer is inserted through the insertion channel in the changer chamber starting at a predetermined insertion depth such that after inserting, the optical element is placed and pivoted in the target position.
摘要:
Transition metals may be recovered from a salt-containing mixture containing at least one transition metal compound, salts, and organic compounds by separating from the salt-containing mixture a mixture of the transition metal compound and the salts. This mixture, together with any organic impurities, is introduced into a combustion zone, and the flue gas/salt mixture leaving the combustion zone is quenched with water. The combustion residue, containing the transition metal, is separated from the resulting quench solution, dried, and converted to fresh catalyst.

A process for the preparation of a 2-methyl-1,3-dicarboxylate by reaction of a 1,3-dicarboxylate with formaldehyde and hydrogen, where, based on 1 mol of dicarboxylate, from 1.0 to 2.0 mol of formaldehyde are used, and either the reaction mixture or 2-hydroxymethyl-2-methyl-1,3-dicarboxylate isolated therefrom as by-product are subjected to thermolysis at temperatures of from 50° C. to 300° C.
摘要:
The invention relates to a process for the preparation of aminomalonic acid esters and optionally their salts by the catalytic hydrogenation of a substituted malonic acid ester in an inert solvent, and optionally by the addition of an acid to the hydrogenation mixture. The process comprises carrying out the hydrogenation in the presence of a solid dehydrating agent and a solvent or solvent mixture in which the aminomalonic acid ester salt is substantially insoluble.
摘要:
A heat producing device utilizing solid carbonaceous material, especially material of cellulosic composition such as corn cobs, as fuel. The heat producing device includes a gasifier for the carbonaceous material. The gas outlet of the gasifier leads to a burner. A cyclonic burning chamber and particle separator are connected to the discharge of the burner. The cyclonic burning chamber and particle separator has a heat outlet and a particle discharge outlet. An adjustable air inlet and mixing chamber are installed in the heat outlet for adding ambient air to reduce the temperature of the heat discharged from the heat outlet. A discharge fan has an inlet connected to the mixing chamber and an outlet for discharging the heat received therefrom to a drying chamber or other heat utilizing source.
