Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus and process for the selective cancel-lation of harmonic frequencies of current produced in a multiphase dynamic stabilizer.  A plurality of multiphase dynamic stabilizers providing electrical stabilization are interconnected to a multiphase AC electrical network via a coupling transformer.  The leakage reactances and turns ratios of the windings of the transformer are such that the phases of selected harmonic frequencies of current produced in each of the stabilizer means are rotated with respect to those of the other stabilizer means with the selected harmonic frequencies being substantially can-celled in each of the stabilizer means.  The harmonics are not the cause of subsynchronous resonance.  The cancelled harmonic frequencies are dependent upon the number of dynamic stabilizers used. Where a dual stabilizer system is utilized, the coupling transformer is forked wye trans-former having the primary windings connected in delta with the principal secondary windings connected in wye and each principal secondary winding having two auxiliary secondary windings connected thereto.  By forming the auxiliary secondary windings such that the ratio of the number of turns therein with respect to the principal secondary winding is about the   0.1%, and the leakage react-ance of the principal secondary winding being equal to about twice the common leakage reactance of the auxiliary secondary windings, the phases of the harmonic currents produced in each stabilizer rotates by approximately 30 electrical degrees with respect to one another leading to the substantial cancellation of harmonic currents of each stabilizer characterized by the series 5, 7, 17, 19...n, p where n = 5 + z; p = 7 + z; and z = multiples of 12.      Addition of shunt capacitors across each of the primary windings creates a static VAR generator having the same harmonic current cancellation attribute.

Abstract: ABSTRACT OF THE DISCLOSURE           A submarine cable with optical fibers which prevents damage to the fibers due to water pressure without the use of an external armor.  The cable has a central core with a strand which provides the cable tensile strength and which is surrounded and contacted by a layer of plastic material has helical grooves which receive the optical fibers which may have a protective covering.  The layer of plastic material is surrounded by a thin metal sheath which, in turn, is closely surrounded by a layer of plastic material.  The grooves and any spaces radially inwardly of the sheath, such as the spaces between the wires of the strands, are filled with a practically incompressible fluid, such as a grease or jelly.  If the optical fiber protective layer is a tube loosely receiving the optical fiber, or optical fibers, the space within the tube not filled by optical fibers is filled with a substantially incompressible fluid.  A further layer of plastic material may be interposed between the metal sheath and the plastic material layer of the core and may at least partially extend into the grooves.

Abstract: ABSTRACT          A process for measuring the cut-off wavelength of higher order propagation modes in optical fibres is based on the fact that the introduction of perturbations in the trans-mission characteristics of an optical fibre can generate greater losses in higher order modes.  A spectral scanning of the fibre output power is effected under a number of different perturbation conditions and the values obtained are combined so as to determine the fraction of power prop-agated in the fundamental mode.  The cut-off wavelength is defined as that where this fraction exceeds a certain value.

Abstract: ABSTRACT     Marine structures are protected from damage caused by icebergs by capturing the iceberg with a towing vessel and towing the iceberg safely away from the marine structure.  To capture the iceberg, an iceberg capturing structure is used which comprises a net having a buoyant head rope and a foot rope which in use is deeply submerged.  Bridles connect the net to the towing vehicle.  The lengths of the lines of the bridles are adjustable so that the head rope contacts the iceberg before the foot rope contacts the iceberg so that the iceberg tends to be rolled into the net structure between those two ropes.

Abstract: START CIRCUIT FOR MICROWAVE OVEN     ABSTRACT OF THE DISCLOSURE         A start circuit arrangement for a microwave oven including a power control relay circuit which is independently responsive to a user actable momentary start switch and to a programmed electronic controller to facilitate operation in a delay start mode. The relay circuit includes a start latch circuit, a door switch and an arm switch.  User actuation of the momentary start switch sets the latch circuit.  A signal from the electronic controller resets the latch circuit.  The door switch is closed by closure of the oven door.  The arm switch is closed by an arm signal from the electronic controller when an actual cooking cycle is to begin.  The arm signal is removed upon expiration of the cooking cycle.          The arm switch, start latch means and door switch are all operatively coupled to the relay such that the relay only enables energization of the power circuit for the oven when the arm switch and door switch are closed and the start latch is set.  In the time delay mode, the latch is set by actuation of the start switch following entry of the operating mode and time information.  At desired start time the arm signal from the controller closes the arm switch enabling energization of the source of microwave energy as well as the blower, the oven lamp, and the mode stirrer motor.

The first and second metal layers consist of a plurality of metal stripes in parallel with each other in alignment with each other, respectively.  Terminal elements of the metal stripes comprises on one sides or on both sides thereof wire positioning walls to facilitate soldering of wires to the terminal elements.  By foldering portions of the terminal elements so as to expose the conductive metal layers, the soldering of the wires to the terminal elements are further facilitated.  Even if distances between the opposite metal stripes attached to a connector housing are not uniform, the multi contacts are uniformly in contact with each other when connectors are connected.  By shifting the terminal elements of multi contacts away from each other keeping their parallelism but not aligned with each other in their longitudinal directions, the difficulty in soldering wires due to overlapping of the terminal elements is eliminated.
