Abstract: Hollow carbon fibers and carbon fibers having a generally C-shaped transverse cross-sectional area (see Fig. 7) are produced by extruding a carbon­aceous anisotropic liquid precursor through a spinneret (14) having a capillary with a generally C-shaped cross-sectional area, into a fiber filament, controlling the viscosity of the molten precursor, the pressure of the molten precursor and the linear take-up speed of the filament to yield a fiber filament having a cross-sectional area shaped substantially like the shape of the cross-sectional area of the capillary and further having a line-origin microstructure, rendering the filament infusible, heating the filament in an inert pre-carbonizing environment at a temperature in the range of 600°C to 1000°C for 1 to 5 minutes, and heating the filament in an inert carbonizing environment at a temperature in the range of 1550°C to 1600°C for 5 to 10 minutes, to substantially increase the tensile strength of the filament. The carbon fiber filament so produced has a line-origin microstructure in which the origin line is located and shaped substantially as a line which constitutes the line formed by uniformly collapsing the perimeter of the transverse cross-sectional area of the fiber filament upon itself. The carbon fiber filament has a tensile strength greater than 200 ksi and as high as the 700 to 800 ksi range, yet a modulus of elasticity on the order of 25-35 msi. The top to bottom outside diameter of the fiber's transverse cross-sectional area is on the order of 30 to 50 microns, and the wall thicknesses are on the order of 8 to 15 microns.

Abstract: A high DC voltage power supply includes a three-phase autotransformer (42) and a three-phase full-wave rectifier (44) applied to the usual motor vehicle electrical circuit (10) of the low DC voltage type. The low three-phase AC voltage of the usual circuit is transformed by the autotransformer to obtain a high three-phase AC voltage which is then rectified by the rectifier to provide a high DC voltage. The load (40) energized by the high DC voltage is ungrounded to reduce the voltage available for inadvertent discharge from either load terminal (62,66) to ground (16). Switching apparatus (46,48,80) is provided for selectively applying the low three-phase AC voltage to the autotransformer only when it is desired to energize the load thereby avoiding at all other times the energy losses that would otherwise be associated with energization of the autotransformer. In one embodiment, the load is a windshield heater element and the autotransformer has multiple sets of input taps (54,56) to provide deice and defog modes of operation, respectively. The tapping of the auto­transformer on the input or primary side yields efficiencies in the construction and operation of the autotransformer. In another embodiment, a current transformer is provided for measuring the AC current through one of the input or output leads of the autotransformer as an indication of the DC current through the load thereby to detect an abnormally low load current condition. The engine driven generator (22) of the motor vehicle electrical circuit is excited from a voltage source (38) independent of the low three-phase AC voltage put out by the generator, at least during any period that the generator is overloaded, thereby to prevent a degenerative collapse in the generator output voltage.

Abstract: All natural water sources are "labeled" by a unique ratio of strontium isotopes (⁸⁷Sr/⁸⁶Sr). In accor­dance with the invention, the strontium isotope ratio for oil bearing formation water and for seawater which is to be injected into the formation is determined. The strontium isotope ratio of the produced water is then monitored at regular intervals and, when the strontium isotope ratio changes to that of the injected water, water injection breakthrough is delimited. The strontium isotope ratio thus serves as a natural tracer for seawater injection.
