Abstract: RCA 76,593 Abstract of Disclosure A color television receiver includes AKB control circuits, operative during periodically recurring kinescope bias control intervals, for automatically adjusting the cathode biases of the receiver's color kinescope.  To ensure the integrity of the bias adjustment operations undertaken by the AKB control circuits, the receiver is provided with a control system which includes: (1) keyed luminance/chrominance gain control apparatus, serving to effectively disable luminance and chrominance signal amplifiers during each kinescope bias control interval; (2) keyed brightness control apparatus for rendering the DC levels of color signal inputs to the receiver's kinescope drivers independent of the receiver's brightness control adjustment throughout each kinescope bias control interval; and (3) a control loop for controlling the DC level of the receiver's luminance channel output, which opposes departures of one of said color signal inputs from equality with a reference voltage throughout each kinescope bias control interval.  A retrace blanking circuit, otherwise supplying beam cut-off biases to the kinescope cathodes during periods of beam retrace, is prevented from such cut-off bias application during beam retrace periods falling within the kinescope bias control intervals.

Abstract: ABSTRACT:          "Multiprocessor computer system which includes n parallel operating computer modules and an external apparatus, and computer module for use in such a system."           A multiprocessor computer system is described which consists of n computer modules. Each computer module includes a processor module and a reducing encoder for forming a data word from a code symbol. The code symbols are broadcast to all computer modules for further pro-cessing, so that a correct data word comprising k symbols can be reconstructed by means of a symbol correcting code, while at the most t code symbols may be disturbed. For the connection of an external apparatus, the latter trans-mits A original versions to a corresponding number of computer modules. The original versions are broadcast to the computer modules as secondary, tertiary, ... versions during successive broadcast steps. Subsequently, decision steps are taken in the opposite sense, that is to say during a last step but one in majority decision is taken each time on the basis of a secondary version and the ter-tiary versions originating from the same original version as the relevant secondary version. When the broadcast has gone further than tertiary versions, majority decisions are taken during a last step but two on the basis of the quaternary and tertiary versions and the relevant majority decision results appear instead of the tertiary versions in the last step but one. During a final decision step, the original version is compared in a relevant computer module with any majority decision result which has been formed in the same computer module and which concerns a different original version.

Abstract: ABSTRACT            A simplified cache with automatic updating for use in a memory system.  The cache and the main memory receive data from a common input, and when a memory write operation is performed on data stored at a memory location for which there is a corresponding cache location, the data is written simultaneously to the cache and to the main memory.  Since a cache location corresponding to a memory location always contains a copy of the data at the memory location, there is no need for dirty bits or valid bits in the cache registers and the associated logic in the cache control. The main memory used with the invention may receive data either from a CPU or from I/O devices, and the cache includes apparatus permitting the CPU to perform cache read operations while the main memory is receiving data from an I/O device.
