Abstract: A waste fabric and lint collector and a cut thread chute assembly for use with an overlock stitching type sewing machine, comprising a collector box, including a front wall, two opposite lateral side walls, and top and bottom walls, a large  see-through window forming part of the front wall thereof.   The  collector  box  is  pivotally  mounted  in  a releasable fashion to the sewing machine frame, wherein the front portion of  the  trimmed  fabric and  lint outlet  is substantially closed by the collector box.  A tubular coupling member has an inner end portion of a shape compl-mentary to that of the top wall of the collector box,  for releasable interlocking engagement therewith, and an outer end portion, for releasably coupling with a complementary flexible air suction conduit  for  discharge  of  the  lint  to  a  waste container.  The chute consists of: an elongated tube, having an enlarged transversely opening mouth at one end,  and a smaller axially opening outlet port at the opposite end.  The chute is anchored at one end to the front edge of the flat-bed of the sewing machine, whereby the tube extends rearwardly beneath the sewing machine flat-bed.  The tube outlet port is adapted to be releasably engaged by a flexible waste conduit for gravity-borne discharge of cut fabric threads to a waste container.

Title: Decryption of retransmitted data in an encrypted communication system
Inventor: PAPPAS SCOTT J
IPC: H04L1/16
Filed: 1997-04-23
Abstract: A method of decrypting retransmitted parts of a message includes receiving (201) a message comprising encryption synchronization and a plurality of encrypted blocks. Until a first block of the plurality of encrypted blocks is received with error, a first keystream is generated (205) from the encryption synchronization and at least one of the plurality of encrypted blocks, and, using the first keystream, the plurality of encrypted blocks, received without error before the first block of the plurality of encrypted blocks is received with error, is decrypted (207). A priming block is determined (211) from the message. When the first block of the plurality of encrypted blocks is received with error, a second message is transmitted (219) requesting a retransmission of the first block. Upon receiving the retransmission of the first block without error, a second keystream is generated (223) from the priming block and the retransmission of the first block and decrypting the retransmission of the first block is decrypted (225) using the second keystream.
