Abstract: The separating valve is intended for discharging the liquid phase of a two-phase fluid. It comprises a seating and a valve member, the latter being actuated to open by a float at the end of a first arm of a lever, whose other arm comprises a cam which engages in a neck of the shank of the valve member. The seating comprises a port at the center of a flat face from which projects a sleeve for guiding the shank of the valve member. Directed towards the flat face, the valve member comprises a flat plate from which there projects a truncated conical valve needle. Between seating and valve member there is defined an annular space communicating by three passageways with the chamber for receiving the liquid phase: one passageway which is an extension of a slot where the lever arm fits, and two passageways along a diameter perpendicular to the slot and tangential to the flat face.

Abstract: A process for deformylation and separation of N-formyl-L- .alpha.-aspartyl-L-phenylalanine methyl ester from a mixture containing both .alpha. and .beta. isomers thereof, which comprises admixing with said isomeric mixture hydrogen peroxide and an organic acid.

Abstract: A roll, for high temperature service in continuous slab casting, has having its sleeve shrinkage-fitted onto the roll shaft under tight contact state, wherein the alloy composition of the sleeve as expressed in % by weight is as follows.The principal components are:C: 0.20 or lessSi: 0.1 to 2.0Mn: 0.1 to 2.0Cr: 10 to 14N: 0.02 to 0.20; providedC+N: 0.30 to 0.35; andin addition to the principal components specified above, permissably one or more components beingNi: 0.1 to 5.0Mo: 0.1 to 2.0V: 0.01 to 0.3W: 0.1 to 0.3, andthe balance is Fe.

Abstract: Radioactive liquids are stored in coils placed in tanks containing circulating cooling medium. The liquid in the coil is circulated by a fluidic pump. In the event of a failure in the pumps circulating the cooling medium the decay heat will cause the cooling medium to boil. A reflux condensor fitted to the tank prevents loss of cooling medium during such periods of pump malfunction.
