Abstract: An apparatus and method for treating a patient suffering from motion sickness such as air sickness and the like. The method includes the steps of applying electrodes to the vestibular area of the patient's head and providing current pulses in the current range of 0.5-3.8 mA, the pulses having a frequency in the range of 1-5 pulses per second and a pulse width in the range of 100-200 msec. The apparatus comprises a timing generator for determining pulse frequency, an impulse generator for generating a pulse waveform, an impulse former for controlling pulse shape and a driver stage for developing current pulses to be applied to the electrodes.

Abstract: A process for the spinning of synthetic fibers comprising dissolving at least one polycondensation product of at least one polyfunctional phenol component with the phenolic groups attached to a central carbon atom so they are hindered in their free rotation and at least one polyfunctional carboxylic acid chloride having an inherent viscosity .eta. inh greater than 0.5 dl/g in a solvent with a boiling point less than 100.degree. C. to form a spinning solution, forcing the spinning solution through spinning nozzles into a liquid precipitant for fiber formation at a temperature at least 8.degree. C. less than the solvent boiling point to withdraw the majority of the solvent from the fibers, stretching the resulting fibers to 2 to 6 times their length and removing the residual solvent.

Abstract: A process for the preparation of aromatic polyesters which are characterized particularly by high-temperature stability and difficult inflammability and which show, in addition, a low development of heat and a high char yield in combustion.
