Patent number: 4555362Abstract: This invention encompasses a method and intermediates for preparing a commercial sweetening agent, .alpha.-L-aspartyl-L-phenylalanine methyl ester. The process involves reacting L-aspartic acid with diketene to form N-acetoacetyl-L-aspartic acid which is converted to N-acetoacetyl-L-aspartic anhydride by reaction with acetic anhydride. N-acetoacetyl-L-aspartic anhydride is reacted with L-phenylalanine methyl ester to provide N-acetoacetyl-.alpha.-L-aspartyl-L-phenylalanine methyl ester which is converted to .alpha.-L-aspartyl-L-phenylalanine methyl ester by reaction with hydroxylamine hydrochloride.Type: GrantFiled: May 15, 1984Date of Patent: November 26, 1985Assignee: G. D. Searle & Co.Inventors: Hugh L. Dryden, Jr, John B. Hill

Patent number: 3968866Abstract: A fluid coupling for driving a cooling fan associated with a vehicle in a ram air stream. The coupling comprises relatively rotatable input and output members. The output member defines a chamber within which the input member rotates. The members have lands and grooves which define a shear space therebetween, and are cooperable with viscous shear fluid to transmit torque therebetween. The output member defines a reservoir chamber located forwardly of the lands and grooves in the ram air stream. An impact pumping ramp on the output member directs fluid from the shear space into the reservoir chamber during rotation of the input member. A temperature-responsive valve arrangement controls the flow of fluid from the reservoir chamber to the shear space. The output member has mounting pads against which fan blades are secured. The mounting pads are located axially on the output member between the lands and grooves, and the reservoir chamber and at least, in part, radially outwardly in the lands and grooves.Type: GrantFiled: November 29, 1974Date of Patent: July 13, 1976Assignee: Eaton CorporationInventors: Wayne K. Leichliter, Rodney H. Detty, John B. Hill
