Abstract: S P E C I F I C A T I O N      TITLE:  STEAM PREHEATING THE ENDLESS FLEXIBLE CAST-ING BELT IN A CONTINUOUS CASTING MACHINE       INVENTORS:  Robert William Hazelett John Frederick Barry Wood ABSTRACT OF THE DISCLOSURE     A continuous casting machine for casting molten metal has at least one thin, endless, flexible casting belt such as in twin-belt casters and wheel and belt casters.  Such an endless casting belt is revolved around pulleys and passes along a casting zone from its input end to its output end.          Method and apparatus are provided for preheating the casting belt with steam closely ahead of the entrance to the casting zone by providing wrap-around steam feed tubes having nozzles, such tubes being positioned in very deep circumferential grooves in input pulley or nip pulley which moves the casting belt into the input end of the casting zone.  These circum-ferential grooves of the input or nip pulley also house wrap-around liquid coolant feed tubes for cooling the casting belt near the beginning of the casting zone.  The wrap-around steam feed tubes also have radial ports positioned to direct steam toward the reverse side of the endless belt, with the port being spaced from the nozzle thereby providing a staged elevation of temperature in the flexible casting belt on the input or nip pulley, while the belt is in contact therewith before the belt reaches the casting zone.  Elevating the temperature prior to the endless belt reaching the casting zone and then suddenly cooling the belt when the molten metal is applied thereto improves casting conditions in the operation of such a thin, flexible casting belt and enhances and speeds up the casting process.  Several ways are also disclosed for preventing coolant water from cooling the steam header and tubes of the bottom nip pulley in a twin-belt machine.

Abstract: ABSTRACT           For the production of cast iron with a vermicular graphite structure (GGV) in a converter it is suggested to desulphurize an initial melt by means of a treatment by pure magnesium and at the same time to treat the melt with magnesium, so that the end analysis shows a proportion of magnesium to sulphur from 0.8 to 2.5.  Experience has shown that the desulphurization and the alloying by means of pure magnesium are less costly than the use of magnesium prealloys and that an exact production of GGV, thereby, is made possible.          It is not necessary to use titanium, that is known for its disadvantageous side effects.  It is, if required, any time possible to change from the production, of GGG to GGV or vice versa, since a charge of the initial analysis, except for the lower remnant magnesium content, is not necessary and, therefore, a separation of the circulating material is not required.  The invention also relates to an apparatus for performing the above treatment.  The apparatus comprises a tiltable treatment container having a reaction chamber situated in the bottom corner area of the container, a closeable opening in the chamber for supplying pure magnesium in the wall of the container, a closure in the top of the treatment container when it is in vertical position and openings in the reaction chamber through which the specified iron melt can penetrate to react with the material in the chamber.

Abstract: ABSTRACT:            Method and system for the mutual encyphered identifica-tion between data communicating stations and stations for use with such method and system.           A method for transmitting ciphered information between two stations while using session keys. According to the method a mutual identification of the stations (AK, A; A,B) is obtained while using an identification device (ID) comprised in each station. Number values (r1, r2), originating from each station, may be exchanged by said identification in a form which is so ciphered that the number values may be recovered by the counter-part only. The session key (tm) is formed on basis of said nunber values in a modification device (MODIFI).          Ciphered data messages are exchanged between the station using the established session key and a message cipher-ing/deciphering device (MCRY, MDECRY) comprised in each station. According to the method the mutual identifica-tion and the establishment of the session key via an open channel may be obtained by transmitting one separate identification sequence in each direction.

Abstract: ABSTRACT OF THE DISCLOSURE         Color video still picture playback apparatus enhances the quality of a color still picture reproduced from a video record medium.  The reproduced signal is formatted as one field of video containing a succession of lines with first and second color difference signals provided in alternating line sequence.  The reproduced picture, after processing, is formatted as alternating first and second fields, each having a plurality of lines such that the lines of the second field are interpolated between successive lines of the first field, and the color difference signals are provided as continuous signals, with interpolated signals being provided in alternate lines.  To achieve this, first and second switches operated at the field rate are associated with first and second delay lines of one-half-line and one line delay times, respectively, and an adder circuit connects the outputs of the delay lines to one input of the second switch.  This interpolates and half-line-offsets the lines of the video signal to produce the interpolated second field of the luminance signal.          Third, fourth, and fifth switches, associated with third, fourth, and fifth delay lines and a second adder circuit interpolate the color difference signals so that outputs of the fourth and fifth switches provide continuous color difference signals.  the third switch is operated at the field rate, while the fourth and fifth switches are operated at the line rate.

Abstract: ABSTRACT OF THE INVENTION         A machine which is operative for handling a roll of wound sheet-like material having a loose tail end includes rollers which rotate the roll in the rewinding direction, blowers which unwind the loose tail end off the roll during rotation, and a delivery table upon which the unwound loose tail end settles for the application of glue.  A first sensor detects the unwinding of the tail end off the roll and activates a normally deactivated second sensor which turns off the rollers when the tail end reaches a predetermined location on the delivery table.  Adhesive is next applied to the stationary tail end by a glue gun which is movably mounted on a pneumatically controlled carriage assembly.  The glued tail end is thereafter rewound upon the roll, and the roll is subsequently ejected from the machine.  A third sensor detects the initial presence of the roll upon the rollers and will initiate ejection of the roll after a predetermined time period elapses, regardless of operation of the glue gun.
