Title: Process for the manufacture of imidazolines.
IPC: C11D3/50
Filed: 1978-12-21
Abstract: The invention provides a process for reducing the diamide content of imidazolines having the formula: < IMAGE > wherein R represents an aliphatic group having from at least 4 carbon atoms and R1 represents an alkyl or alkenyl group having from 1 to 4 carbon atoms.

Title: Air pressure servomotor
IPC: B60T13/569
Filed: 1979-05-31
Abstract: Air pressure servomotor including front shell and rear shell coupled to said front shell so as to construct a housing, a diaphragm disposed in the housing, a piston plate located adjacent the diaphragm, input rod and output rod. The front and rear shells hold a cylinder structure which extends axially from the wall of the front shell to the wall of the rear shell and supports the shells axially, and which has slits running from the forward end to the intermediate portion thereof. A valve having a valve mechanism is slidably disposed in the cylinder structure and having a valve mechanism. Said input rod is connected to the foot pedal and the output rod is connected to the master cylinder.
