Abstract: 1508624 Laying pipe-lines under water SAIPEM SpA 8 Sept 1975 [27 Sept 1974] 36917/75 Heading F2P A method of laying a pipe-line 3 in the sea by means of a surface vessel 1 having a stringer 2<SP>1</SP> and anchored to the sea bed by cables 6, 7 windable on winches 8, 9, comprises welding on the vessel a length of pipe to the free end of the pipe-line being laid, varying the forces exerted by the winches in such a manner as to impart a rapid movement to the vessel in the longitudinal direction of laying over a distance equal or substantially equal to the length of pipe added and, before termination of the rapid movement, applying to the vessel a compensating force of which the direction, sense and intensity are such that together with the forces exerted by the winches it serves to dampen in a continuous manner any induced oscillatory motion of the vessel, by reducing the amplitude of the oscillation produced. The compensating force is preferably generated by variable direction propulsors 12 the thrust of which can be varied by varying the angle of attack or speed of their blades, the direction, sense and intensity of their thrusts being determined and regulated by an electronic computer on the vessel. The method also preferably includes determining the position of the vessel, the angles and levels of the stinger and/or the pipe-line, the tensions in the anchoring cables and their angles of approach to the vessel, the speed and acceleration of the vessel at least during the rapid movement thereof, the direction sense and intensity of the external above-water forces and underwater currents, the number and indication of engines available for driving the propulsors and their speed, the thrust in direction sense and intensity of the propulsors and the forces exerted by the winches and feeding such data to the computer which processes the data and feeds information to the propulsors and winches in such a manner that the thrusts of the propulsors in direction sense and intensity and the forces exerted by the winches on the cables are varied in a continuous manner in accordance with predetermined adjustment criteria in phase opposition to the longitudinal component of the resultant of the forces which induce the oscillatory motion in the vessel or in phase opposition to said resultant when it is required to oppose transverse thrusts generated by underwater currents or other external forces.

Title: Improvements in split-band compansion systems for sound recording or transmission
Inventor: TRENDRELL EDWARD GEORGE
IPC: H03G7/00
Filed: 1967-08-12
Abstract: 1,243,974. Companders. EMI Ltd. 12 Nov.,  1968 [12 Aug., 1967], No. 37138/67. Heading H4R. In a compander system the signal band to be compressed or expanded is split into two partial bands each of which is compressed or expanded independently of the other, and the slopes of the cross-over region of the separating filters employed to derive the partial bands in the compressor and in the expander are related by a factor p which is the reciprocal of the power (1/p) of the amplitude relationship between the input and output of the compressor and equal to the power (p) of the amplitude relationship between the input and output of the expander, i.e. for the compressor: Voltage out = (voltage in)<SP>1/#</SP> and for the expander: Voltage out = (voltage in)<SP>#</SP> In addition the partial ranges of the signals after compression or expansion have to be combined with a 90 degrees phase shift between the partial ranges in order to maintain a level frequency response. This may be achieved using a Norton filter with an odd order Butterworth response to separate the partial bands from the signal band. With an expansion law where #   = 2, providing simple compressors and expanders; although a filter as referred to above may be used in the expander the compresser filter will be a Norton filter with an even order Butterworth response which will require an additional phase shifting network to provide the required phase relation in the partial bands. If p = 3, however, both filters will be of odd order eliminating the need for additional phase shift networks. Circuits for providing the square law or cube law compressor and expander using multipliers or dividers are described with respect to Figs. 3 to 6 (not shown). In addition backward or forward acting multiplier circuits using logarithmic amplifiers employing semiconductors, e.g. zener diodes, to generate the logarithmic characteristic are described with reference to Figs. 7 and 8 (not shown) to provide compansion factors of any desired value.

Abstract: 1,107,257. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 22 July, 1965 [15 Sept., 1964], No. 37641/64. Heading H2K. In a protective arrangement including a rectifier comparator circuit, the two rectifiers O, B are supplied from two balancing windings OC, BC on a common magnetic core carrying a third winding AC to which an energizing component derived from a protected circuit is applied, another energizing component being applied to additional turns on the core or to one of the balancing windings. In the directional relay arrangement shown, the winding AC is wound on the central limb of a shell type core and is energized by a current component I. The additional turns are provided by windings AW1, AW2 wound on the outer limbs of the core and energized by a voltage component. The winding sense of the various windings is such that the relay operating quantity 10 is dependent on the vector sum of the current and voltage components and the relay restraining quantity IB is dependent on the vector difference of the current and voltage components. By providing a further winding, energized by a voltage component, on the central limb the arrangement may function as a polarized mho relay. In a further arrangement, Fig. 7 (not shown), having just the three windings OC, BC and AC on the core, the voltage component is applied across the winding BC. This arrangement functions as an offset mho relay. By interchanging the voltage and current circuits, the last two arrangements may function as a polarized resistance or reactance relay and as an offset resistance or reactance relay respectively.

Abstract: 1361609 Cable joints BRITISH INSULATED CALLENDER'S CABLES Ltd 8 Nov 1971 [7 Aug 1970] 38242/70 Heading H2E [Also in Division H1] An electric cable comprising insulated power conductors (either solid or stranded) and a neutral conductor, has coaxial connectors embedded, at least partially, in the outer insulating sheath of the cable at a number of spaced locations along the length of the cable to each of which a service cable may be attached. The inner conductor of the connector is connected to a power conductor, and the outer conductor to the neutral conductor of the cable. The insulation about each connector may be embossed or coloured for identification, e.g. of phase. As shown, Fig. 2 (c), the connector may include a strap 11 in electrical contact with the neutral conductor 8; insulation 17 separating outer conductors 12 and inner conductors 15 which may be friction-welded to the power conductor as at 14, and may contain a socket 16. Either or both conductors of at least one connector may be of bimetallic construction, e.g. copper and aluminium or aluminium alloy. In one method of making the cable, a hole is formed at each connector-site through the cable to expose a power conductor and the connector assembled as shown, preferably so that the part of the inner conductor to which the service cable is to be connected is perpendicular to the distribution cable. The connectors may then be embedded in plastic so that the covering is integral with or bonded to the cable sheath, e.g. by injecting or pouring the insulating material into a mould or by wrapping with plastics tape which is subsequently heated. An alternative method of making the cable comprises connecting a tubular boss, e.g. 12, to the neutral conductor of the cable and using it as a jig to drill the hole for the inner conductor of the connector. The connectors may also be grouped in pairs as in Fig. 4, with the inner conductor of both connectors being connected to the same power conductor by means of member 46. Straps 53 connect the outer conductor of both coaxial connectors to the neutral conductor 43 of the distribution cable. The paired connectors may be embedded as above; or if the distribution cable has not been sheathed the connectors may be embedded during the subsequent sheathing.
