Title: Apparatus for the processing of an information stream with the aid of an error-correcting convolutional code and for the detection of an error still irremediable in this processing
Inventor: VRIES LODEWIJK BAREND
IPC: H04L1/00
Filed: 1980-09-11
Granted: 1985-01-10
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 of first of all a syndrome former to form a sequence of (n-k)-tuples of syndrome elements from 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 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 residue bits is formed 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. Any other values indicate that an error has remained uncorrected. Such other values are converted into unreliability signals. The unreliability signal indicates a sub-sequence of n-tuples of code elements, in which the errors not corrected are located. Outside this sub-sequence the n-tuples can be reliable again.

Granted: 1986-08-28
Abstract: A jointing machine for the folding of seams in manufacturing of seamed metal sheets made of segments of metal sheets is disclosed, wherein the machine includes a locking wheel pivotably positioned in a recess of a resiliently disposed locking wheel carriage. The seam during formation is supported from below by a support roller, and is held from the sides by an adjustment roller together with the locking wheel. The locking wheel carriage is positioned diagonally relative to the surface of the support roller, which enables the machine to manufacture folded seams in very small metal sheet segments, and to utilize thick or hard metal sheets. The particular arrangement of the jointing machine of the present invention which respect to the locking wheel carriage diagonal positioning enables the locking wheel to penetrate even restricted spaces, and the folding of the seam can be accomplished in several steps wherein the use of the locking wheel carriage ensures the transmission to the seam of sufficient force to form a strong folded joint.

Title: Control circuit for a stepper motor
Inventor: RICHTER LUDWIG
IPC: H02P8/22
Filed: 1984-12-19
Granted: 1989-04-13
Abstract: Control circuitry for a self-synchronously driven step motor under closed loop control includes, for determining the rotor position, a technologically simplified back EMF waveform detector circuit which includes fewer than five operational amplifiers, and preferably only one operational amplifier, and which delivers, for each motor phase, a back EMF signal and the negative thereof. Use can be made of these signals individually or in various combinations, with the aid of a back EMF selector arrangement and an adder connected thereto, for controlling the stator field. By sum and difference formation of back EMF signals by the adder and by assigning such signals each to a respective energization state of the motor phases, the rotor can be moved by half-steps as well as full-steps, to provide a finer degree of control. Additionally it is possible with such circuitry to detect the end position of the rotor and its maximum degree of overrunning, which yield values that can be used for achieving desired damping of the rotor.
