Thank you, Launderess. There is a discussion of these Ultra detergents here and why the manufacturers got away from them. I found them to be very satisfactory for one reason that they failed: they were low sudsing in an era when most washers were top loaders and the moo cows wanted suds on top of the water, which Karen Kenmore the combo did not. A few years later, reintroduced tablets failed because new washers did not use enough water to dependably dissolve them. Vey's mir, it's always something.
