Abstract: An actuator (24) for a ram air turbine system (10) includes a piston rod (42) that is cylindrical in shape and centered about a centerline (A), and stow lock pawls (48) supported by the piston rod (42) and able to move radially. Each of the stow lock pawls (48) has a crown (74) with a crown radius (r2). The actuator (24) further includes a lock bolt (52) extending along the centerline (A) radially within the piston rod (42) and configured to be axially movable within the piston rod (42) between a stowed position and a deployed position. The actuator (24) further includes rollers (57) radially outward from the centerline (A) configured to be guided by the lock bolt (52) and a cylinder (36) having a mating surface (68) with a mating radius (r2). The cylinder (36) is positioned radially outward from the piston rod (42) and configured to be axially movable between the stowed position and the deployed position. A ratio of the crown radius (r2) of the stow lock pawls (48) to the mating radius (r1) of the cylinder (36) is less than 0.98.

Abstract: Die Erfindung betrifft eine Vorrichtung (100) zur Identifikation von Aerosolen, wobei die Vorrichtung (100) das an Aerosolen gestreute Licht unter einer bestimmten Winkelkonstellation mittels zumindest einer Lichtdetektionseinrichtung (110) misst. Aus den Detektionssignalen der zumindest einen Lichtdetektionseinrichtung (110) berechnet die Vorrichtung (100) mittels einer Mess- und Recheneinrichtung ein Polarisationsmaß σ Pol  und, bei bestimmten Ausführungsformen, einen Depolarisationsgrad σ Depol . Anhand des Wertes des Polarisationsmaßes σ Pol  können Wassertröpfchen von durch Brände entstandenen Aerosolen eindeutig unterschieden werden. Anhand des Wertes des Depolarisationsgrades σ Depol  können Staubpartikel von durch Brände entstandenen Aerosolen eindeutig unterschieden werden. Der Winkel, unter dem die Streulichtmessung erfolgt, beträgt 35° oder es erfolgt eine Streulichtmessung bei zwei Winkeln, so bei 5° und 95°.

Abstract: In a battery cooling device for an electric vehicle, a cooling medium supply piping and a cooling medium discharge piping are disposed in a fore-and-aft direction in a middle part in a vehicle width direction of a vehicle body. A plurality of cooling members extend toward opposite sides in the vehicle width direction from both the pipings. A cooling medium passage returns in an outer end part in the vehicle width direction of the cooling member. Therefore, when the vehicle is involved in a side collision, it becomes difficult for both the pipings to be damaged, and cooling medium is prevented from leaking. Also, the cooling medium flows by making a U-turn inside the cooling member, thereby enabling positions on outside and inside in the vehicle width direction of a battery to be cooled evenly.
