    摘要： A method for the manufacture of a high tension ignition cable wherein a tension member is passed through an extruder to form a settable plastic layer thereon. This extrusion takes place under conditions such that substantially no setting of the plastic layer occurs. Thereafter, winding a resistive conductor around the plastic layer to form a plurality of coils at least partially embedded in the layer. The coils are then coated with an insulation layer and a plastic layer is caused to set, thereby fixing the coils in position so that they do not move. The cable made by the foregoing process is also described.

    摘要： Monitoring of the quantity of magnetically permeable particles in a dry dielectric carrier layer surrounding a conductor by passing the conductor with its surrounding layer through a magnetic field created by a magnet to cause magnetic attraction between the particles and the magnet. The degree of this attraction is dependent partly upon the quantity of particles lying in the field and the degree of movement towards each other of the conductor and magnet is monitored while resisting this movement, to give an indication of the particle quantity. A method of controlling the quantity of particles is also described and which uses the monitored movement to produce signals by which the input of particles or carrier into a fluid mixture is adjusted.

    摘要： A cable (20) includes a waterblocking member (29) which includes a superabsorbent polymer. The superabsorbent polymer includes an ionic constituent which is characterized in that its solubility product is substantially higher than that of carboxylate and in that it has a lower reaction rate for forming an anhydride than does carboxylate. The ionic constitutent may be selected from the group consisting of sulfate, sulfonate and phosphate and also includes a counter ion. Other constituents may include a carboxylate and a non-ionic group constituent. The superabsorbent polymer is such that the amount of crosslinking is sufficient to avoid the polymer going into solution, but is not so much as to affect adversely the water absorbency of the waterblocking member. Further, the superabsorbent polymer is much more salt tolerant and temperature tolerant than are prior art superabsorbent polymers.

    摘要： In providing a dried insulation layer upon conductor, a covering fluid layer is initially provided by a process and apparatus in which the layer is formed from composite material comprising magnetically permeable particles homogeneously mixed with a fluid carrier. The fluid layer is formed by passing the conductor through a reservoir of the material and then vertically through a die orifice. The reservoir of fluid applies pressure at the die orifice and this pressure is adjustable to vary the rate at which the material passes through the orifice and thus varies the diameter. This pressure is controllable by adjusting the height of the reservoir above a die orifice or by adjusting gas pressure acting downwardly upon the material. The diameter of the layer is advantageously measured after it is dried and variation in measured diameter from that desired effects a change in pressure to alter the diameter towards that desired. The diameter of the layer may, however, be measured with the layer in fluid form.
