    摘要: Door mounted extendable protectors for protection against damage from bumping by an opening door of another vehicle parked closely adjacent in side by side relation. Resilient bumper elements are mounted outside each car door extended substantially the front to back length of the door. The door extending mechanism is connected via bumper element mounting rods that extend from connection to the extending mechanism out through the outer sheet metal skin of the door to connection with the bumper element. In one embodiment the door bumper extending mechanism is also a retracting mechanism while in another embodiment the bumper element must be manually returned to the retracted state flush against the door when the extending mechanism is not activated.

In this composition, amount of the low molecular weight siloxane component volatilizing from the cured product has been reduced, and as a consequence, this composition is free from the problems such as clouding or haze, contact fault, adhesion failure, and hydrophobicization of the surface caused by the deposition of the volatilized low-molecular weight siloxane component on the surrounding surfaces. More specifically, the addition curing silicone rubber composition comprises; (A) 100 parts by weight of a polyorganosiloxane containing, on average, at least two alkenyl groups which are bonded to silicon atom; (B) 0.3 to 20 parts by weight of an organohydrogenpolysiloxane containing at least two hydrogen atoms which are bonded to silicon atom (SiH functional groups) per molecule; and (C) a catalytic amount of a addition reaction catalyst, and content of the polyorganosiloxane having a degree of polymerization of up to 10 and containing at least one SiH functional group per molecule is up to 0.5% by weight in relation to the entire composition.

    摘要: The present invention provides methods for labeling One or two oxygen atom(s) in a carboxyl group of a carboxyl-containing compound with an oxygen isotope selected from oxygen-17 (17O) or oxygen-18 (18O). The methods of the present invention are characterized in that an activated ester of the carboxyl-containing compound (carboxylic acid) is reacted with H217O or H218O in the presence of an activator. In the methods of the present invention, the reaction between the activated ester of a carboxylic acid and H217O or H218O can be allowed to proceed without including drastic conditions such as strongly acidic conditions or alkaline hydrolysis because an activator is used.
