Abstract: A sequence of k-tuples of information elements is converted by means of an error-correcting convolutional code into a sequence of n-tuples (n greater than k) of code elements. In the processing of the code elements use is made first of a syndrome former (226) to form a sequence of (n-k)-tuples of syndrome elementsfrom the n-received sequence of n-tuples of code elements. From a segment of a number of successive (n-k)-tuples of syndrome elements one or more correction bits (f, ) are formed in each case so as to be able to correct the received code bits and also, if a correction is applied, to be able to update a number of further syndrome bits from that same segment. Furthermore an (n-k)-tuple of secondary syndrome bits or a residue bits is formed (at 252) in each case from this updated segment. A first value of such an (n-k)-tuple indicates the state in which the decoder must be provisionally considered as having corrected all errors in a predetermined sequence of n-tuples of code elements. All other values indicate that certainly an error has remained uncorrected. Such an other value is converted into an unreliability signal. The unreliability signal indicates a subsequence of n-tuples of code elements, in which the errors not to be corrected are located. Outside this subsequence the n-tuples can be reliable again.

Abstract: An improved oxygen sensor of the type adapted for installation in the exhaust conduit of an internal combustion engine. The improved sensor uses a metal oxide element to sense the partial pressure of oxygen in the exhaust gases to which the sensor is exposed. The sensor has a steel body and a ceramic member which extends into the exhaust gases to permit the exhaust gases to produce variations in an electrical characteristic of one of the sensor components. The improved sensor has a perforated protection tube (18) that has a radially extending flange (78). The flange (78) is located between the steel body (12) and the ceramic member (16), which forms a seal preventing exhaust gases from inside the engine's exhaust conduit from leaking beyond the sensor to the atmosphere.

Abstract: Data from a CPU 2 is fed to a DATA portion of a RAM 22 for storage therein, and to a parity generator PG to generate check bits for storage in a check bit CB portion of RAM 22. To read a word, the data and check bit portions are read into latches 24 and 34. The check bits are compared at 32 with fresh parity bits from 26 generated from the data portion. Decoder 38 detects multiple bit (MB), check bit (CB), and data bit (DB) errors, and the latter two are corrected by Exclusive-OR gate sets 36 and 20 respectively. The corrected data and check bits are written back into the RAM, from gates 20 and via buffer 46 respectively. Thus any errors which occur in the RAM are corrected, instead of being allowed to accumulate. Buffers 28 and 48 allow direct access to the CB part of the RAM and the error correcting circuitry for maintenance.

Abstract: Within the spindles made of several parts (1, 2) assembled for the construction of machines, engines and gear boxes, there is provided within the spindle a sealed chamber (4, 5) which is symmetrical in rotation. Parts (1, 2) are obtained through creep extrusion and welded together approximately in their radial plane. This bond may be achieved by means of friction welding, electron bombardment welding, arc welding, shrink ring fitting, force fitting or caulking. The lightening and the facilitation of the manufacture as well as the strength of the spindles are thereby achieved, in particular for the spindles having extremities with decreasing diameters and for which conventional processes produce a considerable amount of worthless turning chips or similar.
