Abstract: Abstract of the Disclosure The present invention provides methods and apparatus for mooring a tension leg platform.  The platform is posi-tioned over an anchor means attached to the ocean floor.          A plurality of guidelines or cables, attached to the anchor means, are called to the surface by means of acoustic recall buoys which are attached to a free end of the guide cables.          The guide cables are then connected to the floating platform.          Tension legs, each including a plurality of tubular leg ele-ments threaded at each end, with threaded couplings connecting adjacent leg elements, are then lowered from the floating plat-form.  Guide means connected between the tension legs and the guide cables direct the tension legs toward the anchor means on the ocean floor.  A hydraulically actuated wellhead connec-tor is connected to a lower end of the tension leg.  The well-head connector engages a wellhead body attached to the anchor means, and is locked thereto upon the sending of a hydraulic signal to the wellhead connector.  The hydraulic signal is di-rected to the wellhead connector through the tubular tension leg.  After the tension legs are connected between the anchor means and the floating platform, the floating platform is deballasted to apply a tensile load to the tension legs.

Abstract: Abstract of the Disclosure The invention relates to electrical devices com-prising conductive polymer PTC elements.  According to the invention, the electrical stability of such devices is improved by restricting access of air to the PTC element so that it absorbs oxygen at a rate less than 10-6 cc/sec/gram.  The devices are for example circuit control devices or self-limiting heaters.  Preferred PTC elements comprise a polymer having dispersed therein carbon black and an additive which stabilises the polymer against degradation, especially an organic antioxidant.  The oxygen barrier may for example be a layer of a polymeric composition or a self-supporting container principally made of metal and filled with an inert gas.

Title: Ssb-fdm communication system derived from  a complex band-pass digital filter bank

Granted: 1982-01-05
Abstract: Abstract An SSB-FDM modulator derived from a complex band-pass digital filter bank and by a filter breakdown process comprises a discrete Fourier transform (DFT) processor capable of giving phase offsets to complex output signals thereof.  In a broader sense, DFT includes inverse DFT (IDFT).  The processor is called an offset discrete Fourier transform (ODFT) processor and is sup-plied with real baseband sample sequences.  The phase offset complex output signals are frequency-selected by a complex band-pass digital filter unit operable at a sampling frequency for the baseband sample sequences into a real SSB-FDM signal.  An SSB-FDM demodulator likewise derived comprises a complex band-pass digital filter unit for frequency-selecting a real SSB-FDM signal into complex sample sequences of the respective baseband channels. The complex sample sequences are ODFT'ed into real baseband sample sequences.  For easier processing of signals transmitted between the modulator and demodulator, use is made of at least one dummy baseband channel.  The phase offsets may be pro-vided in the modulator by a post-processor following a conventional DFT pro-cessor and in the demodulator by a pre-processor prior to conventional DFT. If desired, frequency spectra of the sample sequences of a predeterminded one or ones of the baseband channels may be reversed in the modulator prior to digital filtering and in the demodulator after the ODFT.
