Abstract: The present invention is directed to a method for making lactide from aqueous lactic acid. The invention method comprises converting feed aqueous lactic acid to its vapor phase. The feed vapors then are passed through a reactor maintained at elevated temperature and in which optionally is disposed an alumina catalyst. Withdrawn from the reactor is product lactide, water, and unreacted lactic acid which are subjected to separation for recovery of the lactide product. The separated unreacted lactic acid is eligible for readmission to the process for making additional lactide. This cyclic process embodiment of the present invention comprises the steps of passing make-up aqueous lactic acid feed into a vaporization zone along with unreacted aqueous lactic acid filtrate from another step of the process and therein forming aqueous lactic acid feed vapors. The thus-generated vapors that are passed through a vapor phase reaction zone held at elevated temperature for forming lactide therein. Lactide as a solid is separated from unreacted aqueous lactic acid filtrate; and the filtrate is passed into the vaporization zone in the initial step of the process.

Abstract: The invention relates to a method and a device for the determination of area coincidence of a master to be printed, in particular a printing forme of a printing machine, preferably an offset printing machine, wherein the local remission of a measurement area recorded is determined by optical scanning of the master and the master has an inhomogeneity which is independent of the area coincidence, dependent on the location and influences the measurement result of the scanning. To reduce measurement errors, provision is made for the printing areas to have a different colour (colour difference) in relation to the non-printing areas of the master, for at least two remission values, which differ from one another in spectral terms in accordance with the colour difference, to be determined by each measurement area (12), and for the two remission values to be evaluated to separate a proportion of the measurement result influenced by the area coincidence (fD) from a proportion of the measurement result influenced by the inhomogeneity ( gamma ). <IMAGE>

Abstract: An improved impact pad (10) for a tundish vessel (70) for use in the iron and steel industry includes a plurality of channels (18) which direct the flow of molten iron or steel toward the tundish drains (84,86), and ramps (22,24) which elevate the flow in the directions of the drains. The ramps cause the molten iron and steel to follow a trajectory path after leaving the impact pad (10), first rising and then falling toward the drains. The trajectory path increases the residence time of the molten iron or steel in the tundish (70), allowing more time for impurities to float to the top of the vessel. The trajectory path also helps propel the impurities partially toward the top of the tundish vessel. <IMAGE>

Abstract: A safety lock for house doors and the like, adapted to be operated by a key having a front active profile (3), comprises an outer drum member (4), a cylindrical body (9) rotatably mounted with respect to the drum member and arranged within the latter and a number of safety plates (29) having notches (29a), housed internally to a cavity (13) of the cylindrical body and pivotally mounted around a pin (30). A tab (27) prevents, when the lock is locked, the rotation of the cylindrical body (9) with respect to the drum member (4). By inserting the key in the keyhole, the safety plates reach a reciprocal position which is such that the notches (29a) define a seat which receives the tab (27) thereby unlocking the lock. A cam member (33), which is tiltalble around the pin (30) and is urged by a spring (24), brings the tab back in the locking position when the key is withdrawn. By the oscillating arrangement of the safety plates (29) and the cam member (33), a lock of reduced axial bulk is obtained. <IMAGE>

Abstract: A cargo ramp for an aircraft is constructed of two segments which are hinged together so that they may articulate about the ramp pitch axis. The first of the two segments is hinged to the cargo bed of the aircraft so that it may articulate relative to the cargo bed, again in pitch. The second segment abuts a surface to or from which cargo is to be transferred. The hinged ramp permits straight-across loading and unloading of cargo onto vehicles which have cargo bed heights different than the cargo bed height of the aircraft. In a modified embodiment, the ramp also compensates for a differential roll angle between the second ramp segment and the vehicle cargo bed. In this embodiment, the hinge connection between the two ramp segments permits relative motion of the second segment with respect to the first segment about its roll axis, as well as in pitch.
