The diagnosis routine device DR contains a first decoding circuit OP serving to decode an operation section of the diagnosis command and to form first control signals StS1- StS3 which make it possible to switch through, in the communication controller data channels between a word output register WAR and word input register WER, a fault word register FEWR containing a fault word and an intermediate storing cycle buffer store ZP. The diagnosis routine device DR contains a second decoding circuit BF which is activated via a further first control signal StS4 and which produces second control signals StS5-StS11 by evaluating a command section of the diagnosis command and control circuits and registers of the communication controller may be connected to the word input register WER under the control of in each case one of these second control signals StS5-StS11 for the transfer of the diagnosis command. The fault register FER has fault trigger stages (0-63, Fig. 3, not shown) assigned to individual faults. Fault reaction signals PSS, PVS, FVS and RSA from a fault reaction circuit FSG are fed to the central storage units SE1, SE2 and simultaneously to the above a first internal fault reaction signal is produced which resets the control circuits in the communication controller. A blocking trigger stage SPK may be reversed for the production of a second internal fault reaction signal which blocks cycle selector control ZAWS, the cycle buffer store ZP and an evaluator circuit BW from further activities. The communication controller further includes input and output data devices DE, DA connected to input and output code converters ECW/ACW, a connection register VR, control circuit DSS, a clock UZG and counter stages BSZ, NBZ a subsidiary cycle buffer store shift register NPZ selector circuits AdAW and WAW and registers SSAR AdAR for address information and WAR for word information. A cycle selector control unit ZAWS provides a cycle request signal ZA and receives a cycle acknowledgment signal ZQ. Specifications 1,397,274 and 1,330,040 are referred to.

Abstract: 1,124,978. Sewing machines. O. STROBEL. 19 July, 1966 [4 Sept., 1965], No. 32389/66. Heading DIG. In a blind-stitching machine work is automatically moved, after each sewing operation, transverse to the feed direction so that a series of parallel seams are sewn. The fabric layers are placed over the guide rails 29, 29<SP>1</SP> on a carriage 27, and guided by rolls 54-5 and feed roll 52. During seaming the fabric is guided by the continuously moving carriage and a foot engaging the upper surface. When operations commence the carriage advances the fabric until a feeler roller S8 contacts the front edge of the fabric. The carriage is then momentarily reversed until the roller contacts the rail. The machine then stitches at a high speed until a roller (S9 fig. 6 not shown) rides off the end of the fabric onto the rail. Stitching continues at a reduced speed until a further roller (S10) engages the rail. At the end of the seam the needle is automatically raised; and the cloth bender 35 lowered which effects rotation of the feed roll 52. The carriage then returns to its start position, the bender is raised and the operation repeated. Seams sewn across fabric no wider than the distance between S8-9 are stitched at a reduced speed. When both switches S8, S10 contact the rail the cycle is terminated, the bender lowered and the carriage moved from under the machine. A manual stop switch is incorporated so that trial seams may be sewn. A thread breakage stop motion is operative only when the machine is running at its faster speed. Left and right arm. machines may be grouped side by side.
