摘要： A wheeled carriage for supporting a patient in a substantially horizontal position includes a patient support having head and foot ends and a wheeled base supported by castered wheels. Auxiliary wheels are suspendably mounted on a wheel support structure with the axis of the auxiliary wheels spaced from a midpoint of the wheeled base. A control apparatus controls the wheel support structure to move the auxiliary wheels between a first deployed position whereat castered wheels at one end of the carriage are elevated from a floor surface, and a second stored position with the auxiliary wheels out of engagement with the floor surface. The wheeled carriage includes a drive motor for powering the auxiliary wheels. A drive member applies force to a load cell on the wheeled carriage. The load cell outputs a drive signal to drive the auxiliary wheels. An auxiliary wheel drive and control system accelerates or decelerates the carriage by comparing the drive signal with a threshold value that changes dependent on the velocity of the carriage.

摘要： A liquid curable silicone elastomer composition is disclosed. The liquid curable silicone elastomer composition comprises an organopolysiloxane (A) containing at least two silicon-bonded alkenyl groups per molecule, an organopolysiloxane (B) containing at least two silicon-bonded hydrogen atoms per molecule, a platinum based catalyst (C), an inhibitor (D), and a silica filler (E). The organopolysiloxane (B) is a branched polymer, contains M siloxy units, and the at least two silicon-bonded hydrogen atoms are present on the M siloxy units. The inhibitor (D) is selected from the group consisting of acetylenic alcohols and their derivatives. The inhibitor (D) is present in the liquid curable silicone elastomer composition in an amount to provide a molar ratio of the inhibitor (D) to platinum in the catalyst (C)—of from 150 to 900 (150:1 to 900:1).
