Inventor: KATAHARA KEITH W
IPC: E21B47/08
Filed: 1989-12-19
Abstract: A method for acoustically measuring wall thickness of tubular goods utilizes an acoustical transducer with a large bandwidth and high resonant frequency to measure the thickness of thin walls. The transducer is exposed directly to fluids in the tubular goods and is rotatable 360 degrees to scan the entire circumference of the tubular goods. The transducer is excited and generates an acoustic waveform from the wall under investigation. The acoustic return has a reverberation portion which results from the reverberation of the generated acoustic waveform in the wall. The harmonic frequency content of the reverberation portion is determined and the frequency difference between two adjacent harmonics is determined, from which the wall thickness is determined.

Abstract: A polarization coupler in which a polarization maintaining fiber is employed and a process of producing such polarization coupler are disclosed. Where the polarization coupler is used, beams of light from two laser diodes can be introduced into a single optical fiber and light for the monitoring can be split from a main signal output. Since minimum components required to realize the function are a rotator (8), a birefringent plate 10 and two or three polarization maintaining fibers (2, 4, 6), the polarization coupler is superior in operability in production and is suitable for the miniaturization. The branching ratio of light for the monitoring can be adjusted by adjustment of the angle of rotation of light by the rotator (8).

IPC: G06F15/17
Filed: 1990-07-23
Abstract: A method of data transfer applicable to processing elements (24a, 24b) which are interconnected by a network (18) to form a multiprocessor system, whereby when a datum is to be transferred from a processing element to the network, the datum is sent to a transfer controller (3a) of the processing element at the same time that it is being read out from memory (2a) to be used by the processor (1a) of the processing element, or as it is being generated from the processor and written into memory. Thus, the system performance can be substantially improved, since the time required to execute each data transfer can be "hidden" within the processor execution time.

Abstract: In a method of simultaneously coiling several slit strips formed by longitudinal cutting of a wide metal strip and separated from one another, on a common coiling mandrel of expandable diameter, the leading ends of the strips of all the slit strips to be simultaneously coiled are first fixed at predetermined mutual axis intervals on the coiling mandrel. By rotating the latter, the slit strips are then wound onto the expanded coiling mandrel under tension in more than one initial turn and at least two radially superposed initial turns of the respective slit strip are connected to one another in a manner resistant to tangential shear (resistant to shear in the circumferential direction) in order thereby to form a self-contained sleeve from the initial turns of each slit strip. The connection between the leading ends of the strips and the coiling mandrel is then released and the slit strips are then wound onto their associated sleeves while maintaining the expansion of the coiling mandrel and hence the frictional contact between the latter and the initially formed sleeves. During this process, the torque is transmitted with limited slip from the coiling mandrel to the sleeves by friction between the inner circumferences of the latter and the radially expandable parts of the coiling mandrel, and the back tension is produced in all the slit strips to be simultaneously coiled by a braked uncoiler for the undivided metal strip and/or a longitudinal dividing shear.

Abstract: Uniformity of properties of spun polyamide filaments is improved by treating flake polyamide with successive nitrogen gas streams, the first having a variable temperature and water content, and the second being dry but having a variable flow rate. Viscosity of the molten polyamide from a melter for the flake is determined by measuring differential pressure across a transfer pipe. The viscosity measurement is used by automatic control apparatus to control the flow rate of the second stream, and the moisture content of a make-up stream added to the first stream. The flow rate of the make-up stream is controlled to maintain the second stream within limits, and the temperature of the first stream is controlled to maintain the flow rates of the make-up and second streams within limits.

Abstract: A technique for encrypting and decrypting information signals normally arranged as a succession of lines of active information, with each line having a line timing reference, such as color video information signals. The active video portion is time shifted with respect to the horizontal sync portion of the corresponding line using a predetermined slowly varying time shifting function. The time shifting information is conveyed to the decryption site by encoding the instantaneous value of the time shifting wave form for the beginning of each field in the vertical blanking portion of that field. To provide a reasonable maximum time shifting range, portions of the trailing edge of the active video in the preceding line and portions of the leading edge of the active video in the current line are discarded. During decryption, the original line timing and color burst signals are discarded and new signals are generated which are time displaced from the active videos portion by the original amount before encryption.
