Abstract: Preforms for drawing into glass fibers are relatively quickly produced by extruding filaments or tapes from polysiloxanes and/or heteropolysiloxanes and curing such filaments. A cylindrical wound body is produced from such cured filaments by winding such filaments onto an arbor. The wound body is converted, by heating in an oxidizing atmosphere, into an oxide body composed of SiO2 and, under certain conditions, containing doping amounts of select heteroelements present in the heteropolysiloxane. After removal of the arbor, a gas stream containing chlorine gas is flushed at a temperature of about 1000 DEG  to 12,000 DEG  C. through the oxide body to remove any traces of water and the dry oxide body is sintered into glass at a temperature of about 1200 DEG -1500 DEG  C. The tubular preform thereby attained is collapsed and a glass fiber is drawn therefrom. This process is particularly suitable for the fabrication of gradient optical fibers. A desired refractive index profile can already be taken into consideration in the production of the wound body.

Abstract: The certain quantity of light energy sufficient to effect lifelessness in each of a particular type of hairs, such as is found in a face, arm or back, is provided to the tip of a hand held probe each time a switch is closed, independent of the duration of the switch closure. This relieves the electrologist from having to manually count times, or the number of pulses of light energy applied to a hair body, to effect lifelessness therein. Such counting has been a major part of the photoepilation procedure, and a burden on the electrologist's faculties. In one embodiment, actuating a foot switch provides a series of timed and spaced pulses of light energy for a period, which is selectable by rotating a wiper of a variable resistor-capacitor circuit. The sum of the energies of the pulses over the selected period equals the certain quantity of light energy. In another embodiment, depressing one of four foot switches provides one of four fixed periods of light pulses. In both embodiments, the certain quantity of light energy is first determined for the hair type and then that certain quantity is used for all the hairs of that type to be removed.

Abstract: An arrangement for converting rotary motion into translational motion in which a motion-transmission device that is movable translationally, is divided into two strings that move longitudinally along their direction of motion. A driving motor provides rotational motion through a rotary drive. The strings are guided transversely and are positioned outside of a guide where they become separated. The strings, on the other hand, become united inside the guide, and this guide prevents the strings from being movable from each other laterally. The strings have teeth on sides facing each other in vicinity of the guide, and these strings have ends secured to an intermediate component in the guide, remote from the rotary drive. The intermediate component is common to both strings, and they become disengaged in vicinity of the intermediate component.

Date Nov. 19, 1987.A method and apparatus for detecting and measuring localized corrosion of a metallic surface is described. An array of electrodes fabricated from the same material as the metallic surface is exposed to the same corrosion conditions as the metallic surface. The coupling current between two electrodes of the array is measured, and the electrochemical current noise originating in the electrode array is measured. The two measurements are compared, the electrochemical current noise increasing as compared to the coupling current as the degree to which corrosion is localized increases. The electrochemical current noise originating in the coupled array electrode and the associated electrochemical corrosion potential noise are produced by the natural corrosion processes. The corrosion current is measured by comparison or correlation of the electrochemical current noise and the electrochemical potential noise, the electrochemical potential being measured by means of a third electrode in the array, a reference electrode or a relatively inert electrode. Comparison or correlation of the electrochemical potential noise to the electrochemical current noise provides a resistive noise or impedance, which is inversely proportional to the corrosion current. The corrosion measurement or metal penetration rate is then obtained from the measured corrosion current, as provided by the resistive noise or impedance noise determination, but modified by the degree of localization, as measured by the electrochemical current noise and coupling current determinations.
