Abstract: ABSTRACT OF THE INVENTION       "A FOUR-WIRE LINE ARRANGEMENT FOR USE IN  A DIGITAL TELECOMMUNICATIONS SYSTEM"          ABSTRACT Compensation in a receiving arm of a four-wire line arrangement for cross-talk and echo interference due to signals (S) in the transmitting arm is provided by means of  a ROM S (which can be a C-MOS device)in which are stored coded (delta-modulation) compensation signal values .DELTA. derived empirically when the relevant system is first used.          A pulse generator T, using the transmitted pulses as clock pulses, drives the ROM S to read out the appropriate compensation signal values which are decoded in a decoder D which supplies the resulting compensation signals to a subtractor V which subtracts the compensation signals k from the received signals e. In an alternative form distortion of received signals is corrected by means of a similar pulse generator - ROM - decoder arrangement in which the pulse generator is driven by the distorted received signals and the decoded compensation signals are added to the distorted signals.

Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to an offshore, gravity base, jack-up platform comprising a deck, a gravity base and one or more legs interconnecting the deck and base.  The gravity base comprises a generally polygonal shaped, monolithic hull structure with reaction members extending downwardly from the hull to penetrate the waterbed and react to vertical and lateral loads imposed upon the platform while maintaining the gravity hull in a posture elevated above the surface of the waterbed.         A method aspect of the invention includes the steps of towing a gravity base, jack-up platform, as a unit, to a preselected offshore site floating upon the gravity hull.  During the towing operation, the deck is mounted adjacent the gravity base with a leg or legs projecting through the deck.  At a preselected offshore station ballast is added to the gravity base and the platform descends slightly to a posture where the platform is buoyantly supported by the deck.  The base is then jacked down toward the seabed and the platform is laterally brought onto station.  Ballast is then added to the deck and the reaction members are penetrated into the waterbed to operational soil refusal.  Ballast is then ejected from the deck and the deck is jacked to an operational elevation above a predetermined statis-tical wave crest height.

Abstract: ABSTRACT OF THE DISCLOSURE    Conjugated polymers are doped with ionic dopant species to a preselected room temperature electrical conductivity ranging from that characteristic of semi-conductcr behavior to that characteristic of metallic behavior, by means of reversible electrochemical dop-ing procedures.  The doping procedures are carried out in an electrochemical cell wherein the polymer to be doped is employed as one or both of the electrodes, and the electrolyte is a compound which is ionizable into the ionic  dopant species.  Upon operation of the cell, the polymer, if used as the anode, becomes doped with an anionic dopant species to a p-type material; or if us d as the cathode, becomes doped with a cationic dopant species to an n-type material.     The electrochemical doping reactions and their reverse electrochemical undoping reactions are utilized as the charging and discharging mechanisms of novel lightweight secondary batteries which employ doped or dopable conjugated polymers as one or both of their electrode.

Abstract: METHOD FOR FORMING IN SITU MAGNETIC MEDIA IN THE FORM OF          DISCRETE PARTICLES              Abstract of the Disclosure A method of forming discrete magnetic particles in situ by dispersing a nickel hypophosphite solution in a binder and binder solvent,  such as polyvinyl alcohol in water or polyester urethane polymer in an organic solvent, forming a coating from the nickel hypophosphite binder solution on a substrate, and exposing the coating to a radient energy source, such as x-rays or an electron beam.  Thereafter the incipient magnetic media in the area exposed to radiation is developed by contact with a solution including ions of at least one of cobalt, nickel and iron and a reducing agent, such as a hypophosphite ion, to produce a magnetic media of discrete magnetic particles within the binder in the area exposed to the radiant energy while not forming such mag-netic particles in other unexposed areas of the nickel hypophosphite coating.

Abstract: Abstract of the Disclosure The invention relates to moisture-resistant particles that intumesce in large volume when exposed to heat.  The particles comprise a core particle that comprises a hydrated silicate glass and a protective moisture-resistant coating surrounding the coro particle.  The protective coating includes an ingredient that is ionized in the presence of water to provide metal cation capable of reacting the silicate ion of the core particle to form a reaction product that is less water-soluble than the silicate glass of the particle thereby limiting action of water on the core particle.  The particles are useful in fire-retardant asphalt roofing materials.

Abstract: ABSTRACT         A circuit for controlling the clock rate separately for each facet of a polygon used in a laser driven raster output scanner. The clock rate for facet #0 is servoed using a first order integrator (11) driven by a digital correction circuit which compares the actual number of pulses against the required number, and produces therefrom an analog correction pulse width which is applied to the integrator (11). A second order integrator (19) is used to compensate for leakage of charge from the parallel capacitor of the first order integrator (11), to improve performance. The remaining facets are then corrected for by assigning to each an individual correction voltage. This correction voltage is generated by counting clock pulses for each additional facet and using these pulse totals to generate individual analog correction voltages which are added to, or subtracted from the facet #0 voltage in an adder (18) which combines the facet #0 correction voltage with each individual voltage in sequence. The result is a relatively simple and inexpensive circuit that compensates for facet signature errors, as well as errors produced by drive motor hunting.

Abstract: ABSTRACT OF THE INVENTION     In electric energy transmission equipment it is often necessary to connect high-tension lines and the like together.  In order to avoid negative effects reflecting back into the line network and the generators, the phase angles of the alternating voltages to be connected together must agree.          For this purpose, in practice, capacitive or inductive reactive powers have hitherto been connected into the circuit.  Such compensation can be continuously carried out by means of a method and a device for carrying out the method, which considerably  increases operational reliability.   For this purpose, a correcting voltage (UZ) is inductively added to a high-tension line (HL) via a correcting transformer (ZT).  The correcting voltage  (UZ)  is composed of a voltage  (UK)  = constant, originating from an exciter transformer (ET), and of a controlled or regulated voltage (UV) which is continuously adjustable and the phase relationship of which is variable, from a voltage source (1).
