Abstract: ABSTRACT           Disclosed is a method for interconnecting one or more adjacent speech channels between a carrier-frequency system in which a basic primary group is obtained by the principle of pre-modulation, and a system in which a basic primary group is obtained by the principle of pre-group modulation.  The basic primary group of the pre-modulating system with one of its channel car-riers, is converted in such a manner that the channel group to be intercon-nected reaches the frequency position of an interconnect filter of which the band width corresponds to that of the channel group.  The band screened  out by the interconnect filter is converted directly, by a carrier of the pre-modulating system, into the desired frequency position of the basic primary group of the pre-group system.

Abstract: ABSTRACT           This relates to an apparatus and method for providing an accurate data group to the instruction buffer of a data pro-cessing system.  The data group is simultaneously applied to the instruction buffer and to the error correcting apparatus.          After analysis of the data group in the error correcting ap-paratus, the operation in progress is aborted if an error has been detected, and the error is not correctable.  If correctable, the correct instruction data group is applied to the execution unit.      If no error is detected in the data group, utilization of the data group proceeds uninterrupted.  Two, three state busses are employed.  The first three state bus is used to transmit memory data to the error detection and correction (EDAC) circuitry, to transmit corrected data from the (EDAC) circuitry and to the data output circuits and to transmit input data to the memory.          The second three state bus transmits data to the instruction buffer, to the EDAC circuitry and also transmits corrected data from data output circuits to the instruction buffer.

Abstract of Disclosure               -An apparatus for cooling the neck moil of a blown container so that such moil can be easily removed from the container is disclosed.  The apparatus has a main body portion which is connected to the rod of a blow pin cylinder so that the apparatus can be moved towards and away from the blow mold,  The main body portion also has attached thereto the blow pin, a cutting collar and a rotation collar.  To feed blow air to the blow pin, the main body portion provides an air channel.  An annular cylinder is formed in the body por-tion which cylinder accepts an annular piston which piston has a cooling plate connected thereto.  The cooling plate is designed to contact and flatten the moil against the cold blow mold so that the moil is cooled.  By feeding compressed air to the cylinder at it upper end, the cooling plate is moved to contact the moil and by feeding compressed-air to the cylinder bottom the cooling plate is retracted from the moil.  in operation the apparatus along with the blow pin and the two cutting collars are lowered by the blow pin cylinder so that the blow pin enters into the extruded tube.  The cutting collar pinches the moil at its juncture with the container neck while the rotation collar engages the moil. The tube is blown to the shape of the mold and the cooling plate presses down onto the hot moil and flattens it into a doughnut-like disk against the cold mold.  The cooling plate moves upward away from the cooled moil and the blow pin along with the apparatus and collars are retracted away from the mold carrying with them the cooled, flattened moil.  The cooled moil is then knocked from the rotation collar by a second downward motion of the cooling plate.   The cooling plate returns to its uppermost position and the cycle is repeated.
