Title: Electric esp. telephone cable has internal laminated sheath - with plastics lapped edges to contact extruded outer sheath
Inventor: KOYAMA SUSUMU
IPC: H01B13/10
Filed: 1975-09-20
Abstract: Cable mfr. involves sheathing it in a laminated metal-plastics band closed around the cable with a longitudinal joint, then extruding an outer casing onto this. A plastics band is first thermally bonded to a metal band, one or both edges of the plastics extending beyond the edges of the metal; secondly, differential tensions are applied at the edge(s) of the plastics to pull and fold the edge(s) over the metal and towards the centre-line, and simultaneously bond these laps to the metal; thirdly, the resultant laminated band is applied to the cable longitudinally, with a plastics-to-plastics joint. Finally the (conventional) external sheath or casing is extruded around this. There is no exposed metal (e.g. aluminium) at the longitudinal joint. Consequently an air-gap does not form between this joint and the extruded outer casing.

Patent DE-2630304-A1 (DE)
Inventor: ROSENBAUM WALTER STEVEN
IPC: G06V30/262
Filed: 1976-07-06
Abstract: A digital reference matrix apparatus is disclosed for verifying input alpha words from a keyboard, character recognition machine, or voice analyzer as valid linguistic expressions. The organization of the digital reference matrix is based upon the character transfer function of the input apparatus. The digital reference matrix contains a vector representation for each dictionary word in the form of a calculated vector magnitude and unique vector angle. The set of magnitudes and angles is stored in the digital reference matrix using a form of run length coding by storing a single magnitude pointer followed by the chain of unique angles for words having the same magnitude. The vector magnitude so calculated constitutes the address data for accessing the digital reference matrix. When an input word is received for verification, the word's magnitude and angle attributes are calculated and the digital reference matrix is accessed at the magnitude of the input word and the corresponding angles are searched for a match. An output signal is generated indicating whether or not the input word is valid. The organization of the digital reference matrix minimizes the size of the array needed for accurate word verification representation through the use of the combination of digital angle representation and run length compaction of the magnitude/angle verification syntax.
