Abstract: ABSTRACT:          An error correction circuit in a television receiver for receiving, for example, Teletext informa-tion, Viewdata information or information of comparable systems.  The codes representing symbol information received by the receiver are classified into one out of two or more classes in dependence on the probability of their occurrence, this classification being an indica-tion of the extent to which it is probable that a newly received code is correctly received, if different from the information stored in the corresponding symbol loca-tion.  Such a television receiver includes a receiving section, audio and video amplifiers and a picture tube. A text decoder receives symbol information to be stored in an information store which information store can be read out to display text on the picture tube.  An error circuit detects whether newly received information is different from the information stored for the same symbol location with the use of a comparator and two parity circuits.  Although the code used does not have a parity bit, the parity circuitry is used to determine whether a newly received code has a lower probability of occur-rence than the stored code to inhibit overwriting the information in the information store with the newly received information.  In such a case a flag bit for the corresponding symbol location may be set to indicate that the stored code is suspect.  Such an error circuit makes it possible to correct nearly 100 percent of the errors in the text as soon as the next text repeat is received even if the used code does not contain any redundancy.

Abstract: CAN BEADING APPARATUS Abstract of the Disclosure Apparatus is provided for forming a chime bead adjacent the closed end of a seamless cup-shaped metal can body and a plurality of peripheral beads intermediate the opposite ends of the can body.  The apparatus includes a plurality of beading spindles receiving and supporting can bodies for movement along an arcuate path.  The beading spindles are provided with beading tool portions correspond-ing to the chime and intermediate beads to be formed on a can body.  The frame supports axially offset and sequentially arranged outer beading rails positioned along the arcuate path of spindle movement.  During movement of the spindles along the path between input and output stations of the apparatus, can bodies on the spindles are rotated about the spindle axes and, as each can body moves past the outer beading rails, the beading tool portions of the spindles and the outer beading rails cooperatively engage a can body therebetween to sequen-tially form first the chime bead and then the intermediate beads on the can body.  The outer beading rails are supported on the frame of the apparatus for adjustment of the positions of the beading rails axially, laterally and radially with respect to the axis of the arcuate path of movement of the spindles.

Abstract: REDUNDANCY SCHEME FOR A DYNAMIC RAM                ABSTRACT OF THE DISCLOSURE         A redundancy scheme is described for replacing defective main memory cells in a dynamic RAM with spare memory cells.  The spare cells are arranged in groups of spare rows and spare columns of memory cells such that a plurality of groups of spare rows and columns of cells are substituted for defective main rows and columns of cells so as to repair relatively large defects which impair adjacent rows and columns of main memory cells.  In the preferred embodiment, the RAM includes a plurality of address buffers, each of which receives an incoming row address bit and then an incoming column address bit for sequentially outputting row and column address data, Associated with each buffer is a store for a defective row address, a store for a defective column address, and a comparator.  The stores retain defective memory cell addresses which the comparator sequentially compares against the address data sequentially output by the buffer.  When the comparator senses a match, a control signal is generated to initiate substitution of spare memory cells for the defective main memory cells.

Abstract: PROCESS FOR THE PREPARATION OF ALLOY POWDERS WHICH CAN BE SINTERED AND WHICH ARE BASED ON TITANIUM                 ABSTRACT OF THE DISCLOSURE    The invention relates to a process for the preparation of alloy powders, which can be sintered and which are based on titanium, through the calciothermal reduction of the oxides of the metals forming alloys in the presence of neutral additives.          The process is characterized by the fact that titanium oxide is mixed with the oxides of the other components of the alloy in amounts, based on the metals, corresponding to the desired alloy, alkaline earth oxide or alkaline earth carbonate is added in a molar ratio of metal oxides to be reduced to alkaline earth oxide or alkaline earth carbonate of 1 : 1 to 6 : 1, the mixture is homogenized, calcined at temperatures of 1000°C to 1300°C for 6 to 18 hours, cooled and comminuted to a particles size of ? 1 mm; calcium is added in small pieces in an amount equivalent to 1.2 to 2.0 times the oxygen content of the oxides to be reduced, a booster is added as well in a molar ratio of oxide to be reduced to booster of 1 : 0.01 to 1 : 0.2, the reaction batch is mixed, the mixture molded into green compacts and filled into a reaction crucible which is closed off; the reaction cruci-ble is placed in a reaction furnace, which can be evacuated and heated, the reaction crucible is evacuated to an initial pressure of 1 x 10-4 bar to 1 x 10-6 bar and heated to a temperature of 1000 C to 1300°C for a period of 2 to 8 hours, then cooled and the reaction crucible is taken from the reaction furnace, the reaction product is removed from the reaction crucible and crushed and milled to a particle size ? 2 mm, the calcium oxide is then leached out with a suitable dissolving agent which does not dissolve the alloy powder, and the alloy powder obtained is washed and dried. The alloy powders  obtained have a uniform composition of the structure, are free from segregations of oxides, nitrides, carbides and/or hydrides.          They have high bulk and tap densities. The alloy powders can therefore be molded by isostatic hot molding to components approximating the desired contour. The alloy powders are particularly suitable for the manufacture of parts, subjected to high mechanical stresses in aircraft construction.                             - 1a -
