IPC: B60C9/00
Filed: 1967-12-28
Abstract: 1,150,860. Polyamide filaments and process for making them. E. I. DU PONT DE NEMOURS & CO. 28 Dec., 1967, No. 58847/67. Heading B5B. Crystalline oriented filaments of a polyamide consisting primarily of the following recurring structural units wherein n is 9-14, preferably 10, at least 70% by weight of the diamino constituent of the repeating units being of a trans-trans stereoisomeric configuration, and the filaments having a transverse crystal spacing of 4À3 to 4À7Š, as determined from the strongest equatorial reflections in a Bragg X-ray diffraction pattern may be produced by drawing melt spun filaments of the polymer while they are at a temperature t (‹C.) exceeding 290+S-15 m+20 (- 1)<SP>m</SP>, where m is the total number of carbon atoms in the aliphatic diacid and S is the trans-trans stereoisomer content of the diamino constituent of the repeating unit in per cent by weight, said temperature being below the softening point of the polymer and preferably not above the viscous flow drawing temperature. The drawing is preferably carried out in two stages, the temperature being higher in the second stage. The second stage drawing is normally part of a drawing process wherein the filaments attain an orientation equivalent to that obtained with at least a 3À5: 1 draw ratio. The melt spinning of the filaments is preferably effected into a heated inert gas such as nitrogen or steam to prevent excessive spinning orientation and render the filaments more highly drawable subsequently. The molecular weight of the polymer is preferably at least 18,000 and more preferably 25,000 to 35,000. The polymer is a polyamide formed by the polycondensation of bis-(4-aminocyclohexyl)- methane and aliphatic diacids of 11 to 16 carbon atoms. Copolymer components, whether the foreign component replaces the amine, the acid or both, should preferably be kept to no more than about 10% by weight (calculated as the weight per 100 grams of polymer of where X refers to the acid entity in the foreign component, Y refers to the amine entity and Z refers to an amino acid component). In an example, a polymer prepared by polycondensation of bis-(4-aminocyclohexyl) methane of 70% trans-trans stereoisomer content and dodecandioic acid, said polymer having a relative viscosity of 115 (measured in 98% formic acid) is melt spun at 295‹ C. and the yarn thereby formed is drawn at a draw ratio of 3À56 over a snubbing pin maintained at 100‹ C. The yarn then travels in a helical wrap around a pipe with a temperature gradient of 150‹ to 190‹ C. (increasing in the direction of yarn travel) to a total draw ratio of 4À0. The yarn is finally further drawn at a draw ratio of 1-49 over a hot pin at 150‹ C. and a 2-zone hot-plate heated to 200‹ and 210‹ C.

Filed: 1973-12-19
Abstract: 1454290 Data storage systems INTERNATIONAL BUSINESS MACHINES CORP 19 Dec 1973 [26 Dec 1972] 58903/73 Heading G4C A counter counts signals written in to a buffer store, and a second counter counts signals read from the store. The difference in the counter outputs is used to detect the end of a sequence of signals passed to the store and to determine whether a predetermined number of signals is present in the store. In the embodiment described the signals are data bytes which are to be recorded in groups of seven parallel-bit bytes on multi-track magnetic tape. Each recorded group includes a check byte and check bits. The counters both count modulo-32 and respectively specify which of the 32 addresses in the buffer shall receive or supply a byte. If the difference count is greater than 6 a full group of data bytes is in the buffer. The group is transferred as a burst of bytes to another buffer leading to an encoding circuit which feeds the recorder write-in circuit. If the difference count becomes less than 7, indicating that there are insufficient input signals to complete the final group, the generation of padding signals and an end of record group is initiated. The padding signals fill the incomplete group. The number of data bytes in that group, as indicated by the count difference, is recorded with a check byte group which follows the end of record group. The modulo-32 count of the total number of data bytes is also recorded with the check group. Signals read from the tape pass to decoding circuits which pass decoded data bytes to storage from which they are read in bursts of 7 bytes to the buffer, under the control at the write counter. The data bytes are read byte by byte from the buffer to, for example, a data processor. Read-out from the buffer is stopped when the read counter shows the same value as that of the modulo-32 count in the check group. Should read-out from the tape be in the backward direction write-in to the buffer is started when the appropriate number of padding bits has been read out, as determined by reference to the difference count in the check group.
