Abstract: In the manufacture of Cheese of the "pasta filata" type, an intermediate product is obtained by carrying out the coagulation of a protein concentrate, obtained by ultrafiltration of milk, by means of an acid whose concentration is selected so that the calcium concentration, in the coagel resulting from the coagulation, after separation of liquid, is below about 1.5% calculated on the weight of fatfree dry solids.

Abstract: A ladder intended for use in boarding small boats has side rails and treads interconnected by integral and precut joint elements designed for ready connection and disconnection. The connected treads and rails are suspended from the deck or side of a boat by crank-like hangers pivotally and releasably secured to the side rails and having grooves enterable by one of the treads. Anchoring members on the hangers engage corresponding fittings permanently secured to the boat to suspend the ladder over the side of the vessel. One of the treads has braces which engage the sloping side of the boat to keep the ladder rails generally vertical.
