Title: Device for inserting a thread-warp overlength, forming during the sewing of a hemstitch on a textile article, into the open end of this hemstitch
Inventor: MUESSIG KARL
IPC: D05B65/06
Filed: 1984-05-09
Abstract: During the sewing of a hemstitch 13 on a textile article 10, thread-warp overlengths 12' form and are to be inserted into the open end of the hemstitch 13. The device for this has a press plate 55 for fixing the article next to the end of the hemstitch 13, furthermore a press-down lever 57 which opens the hemstitch 13 in a tubular manner in the region of its end. A reciprocally pivotable hollow finger 64 having an orifice near its free end opposite the thread-warp overlength 12' is subjected alternately to suction and compressed air. As a result of the suction prevailing in the hollow finger 64, the thread-warp overlength 12' is sucked through the orifice into this, and when the thread-warp overlength has been sucked in the finger 64 penetrates into the hemstitch 13 open in a tubular manner. The hollow finger 64 is then subjected to compressed air, so that the thread-warp overlength 12' is ejected inside the hemstitch 13, whilst at the same time the finger 64 retracts from the hemstitch 13. When the press-down lever 57 then moves back into its initial position and the press plate 55 is lifted off, the thread-warp overlength 12' is retained by friction in the hemstitch 13 which flattens again. <IMAGE>

Title: Fast nB/mB coder
Inventor: HANKE GERHARD DIPL ING
IPC: H03M5/14
Filed: 1984-12-05
Abstract: This coder converts an n-bit signal into an n-bit word by means of a code table stored in a coder (C-ROM). Two code modes (+mode and -mode) are used in familiar manner, the +mode exhibiting only neutral signals and those with an excess of 1-bits and the -mode exhibiting only neutral signals and those with a shortfall of 1-bits. In the known coder, the selection of the mode is obtained only from the recoded m-bit word. In the arrangement according to the invention, the required code is determined in parallel with the coding in an analyser (M-ROM in Figure 4). The logic required for forming the word-wise running digital sum with respect to the excess 1-bits of the m-bit words can be designed to be very simple by advantageous programming of the analyser (M-ROM). It is possible, particularly in the case of a 7B/8B coder, to use the circuit variant of the wired OR which considerably shortens the total signal transit times, in this case only the sum of the signal transit times of a ROM of an NOR circuit and of a D-type flip flop and contributes to an additional increase in the coding speed. <IMAGE>
