Title: Remediation of electrically heated conduits
Inventor: Davide Gorgoglione
IPC: H05B3/40
Filed: 2021-04-29
Abstract: A remedial star connection system for an electrically heated conduit 12 (e.g. pipeline used in the subsea oil and gas industry), the system comprising: a first connector 28 that comprises at least two contacts 34 arranged to connect with at least two contacts of a complementary first terminal (e.g. socket 30); a second connector 28 that comprises at least one contact arranged to connect with at least one contact of a complementary second terminal; and a coupling 38 between the first and second connectors, the system being arranged to effect short-circuit connection via the coupling between the at least two contacts of the first connector and the at least one contact of the second connector. The connectors are coupled together so that when they are engaged with the terminals, short-circuit connection is effected between the additional cable and at least two intact cables of the group to reinstate a working heating circuit. The system can be pre-configured to remediate faults in different cables of a group. The connectors may be wet-mateable for subsea conduits.

Title: System for transforming and correcting digital sound signals
Inventor: MOURTZOPOULOS IOANNIS
Filed: 1998-07-08
Abstract: The invention refers to an electronic digital system for transforming digital data of a Pulse Code Modulation, PCM, which constitute the usual form of data in several digital sound devices and systems (Compact DIsc, Digital Audio Tape and others), into a pulse series signal with Pulse Width Modulation, PWM and for reducing the non-linear and other distortions appearing during this transformation. It concerns an autonomous system which, either operates independently, or is combined with other stages of a digital sound amplifier or a digital to analog converter and which interferes in the sound reproduction chain as illustrated in fingures 2a, b, c between the digital sound source and the next stages which either are the Digital to Analog Converter, DAC), or the principal amplification stage (PCM amplifier). This system implements a transformation tof the PCM encoded stereo digital sound data, to an 1-bit pulse series with Uniform-sampled, Double-sided Pulse Width Modulation), with simultaneous suppression of the non-linear and other distortions that are known to be created suring the transformation of data from PCM to PWM.

Abstract: A heat exchange structure is constructed from refractory blocks having three linearly aligned flue-forming openings extending from top to bottom of the block. The central opening is surrounded on four sides by refractory and the two end openings are surrounded on three sides. These refractory shapes are assembled in an open basketweave structure to form the heat exchanger. The resulting structure contains vertically extending, interconnected flues of two types, (1) flues of a first type interconnected at alternate layers in the structure to each of the four contiguously adjacent flues and (2) flues of a second type connected to opposed pairs of contiguously adjacent flues at alternate levels and to the other pair of contiguously adjacent flues at the intermediate levels. The net result is a stable heat exchange structure with relatively thin walls, relatively large flues, and means for creating turbulence in gas passing through the exchanger, thus increasing the rate of heat exchange.
