Abstract: ABSTRACT OF THE DISCLOSURE         A detecting device for detecting abnormality in the tape travel, comprises detectors for detecting capstan rotation pulses which have a frequency in accordance with the rotational speed of a capstan which drives and causes a tape to travel, supply reel rotation pulses which have a frequency in accordance with the rotational speed of a supply reel which pays out the tape, and take-up reel rotation pulses which have a frequency in accordance with the rotational speed of a take-up reel which takes up the tape, and a detecting circuit supplied with the three kinds of rotation pulses, for detecting abnormality in the tape travel and for producing an abnormality detection signal which indicates that an abnormality has been detected in the tape travel.  The abnormality detecting circuit comprises a microcomputer for carrying out steps of counting the received capstan rotation detection pulses until a counted value of the capstan rotation pulses reaches a predetermined counted value, discriminating whether a supply reel rotation pulse was received during the counting period of the capstan rotation pulses, discriminating whether a take-up reel rotation pulse was received during this counting period, discriminating whether a capstan rotation pulse was received within a predetermined time period, and generating the abnormality detection signal when any one of the three discriminated results is "NO".

Abstract: ABSTRACT           A method is described for the differential diagnosis of rheumatological diseases.  Sera from patients with SLE; MCTD, and RA are screened for antibodies directed against RNA polymerase I  using a solid phase immunoassay. Significant levels of the antibodies were detected with sera of all SLE and MCTD patients and in 78% of the RA patients. No detectable anti-RNA polymerase I antibodies were detected in the sera of healthy individuals.          Sera from patients with SLE contained immunoglobulins directed against the S3 subunit of RNA polymerase I, as well as antibodies to the S2 or S5 subunits, RA patient's sera contained antibodies only to S3 while MCTD patients sera contained antibody to S4 in addition to antibody to the S3 and S5 subunits.  The identification of specific reaction patterns of the antibodies with the individual subunits of the RNA polymerase I is indicative of a particular class of rheumatological disease.   To date, it has not been possible to distinguish among different rheumatic diseases.

Abstract: A GROUP CODING SYSTEM FOR SERIAL DATA TRANSMISSION             ABSTRACT OF THE DISCLOSURE           A run-length-limited group coding system is provided wherein the code permits a high data transfer efficiency.  Code values for both data and control functions are chosen such that the maximum cumulative DC deviation from a nominal center is no more than 10 percent averaged over a data transmission sequence. The code employed limits the maximum number of zero bits between successive one bits in a serial binary sequence to a predetermined value thereby permitting self-clocking.  The coding system is particularly suitable for use in baseband data transmission systems where the transmission medium is either an electrical or optical link.  Code values for control functions meet the same constraints as those for data and protocols are established such that the coding system may be integrated into a variety of multiple-unit system configurations wherein the communication between units is, for example, by way of a point-to-point link, or a bus, star, loop, or ring arrangement.

Abstract: A synthetic resin pipe which includes two identical complementary, extruded semi-cylinders joined by electromagnetic bonding along abutting longitudinal edges to form a smooth walled cylindrical pipe. In one embodiment of the invention, the smooth walled pipe forms an internal sleeve or liner within an external corrugated pipe having contiguous circumferential corrugations over its length, and having the troughs of the corrugations bonded to the outer surface of the internal sleeve. In the method for forming the pipe, two identical flat plastic sheets are extruded, then vacuumed formed into semicylinders each having radially outwardly projecting longitudinal flanges extending from opposite side edges thereof. A paste or dispersion containing ferro-magnetic particles is then applied to the flanges on the sides thereof adjacent the concavity of the respective semi-cylinder. The semicylinders are next arranged in registry to form a cylinder with the flanges abutting. Radio frequency electromagnetic radiation is then directed through the semi-cylinders at the location of the ferro-magnetic particles to fuse the semicylinders to each other adjacent the flanges. The flanges are then sheared away along shear lines tangential to the cylindrical side wall of the pipe thus formed.
