Abstract: FIELD: electric tape drives of sound-recording devices. SUBSTANCE: controlled valve-type electric motor has electromechanical frequency changer with permanent-magnet inductor and armature winding whose coils are connected to output of frequency changer built as voltage inverter, logical control unit, comparators, two groups of integrating circuits, and voltage limiters. Integrating circuits and voltage limiters provide for shaping signals across comparators output of 180 deg, length, spaced 120 deg apart, and symmetrical relative to rotational emf signal. Logical unit actuated by these signals ensures sequential ON/OFF operation of switches in anode and cathode groups of frequency changer to connect armature winding coils to power supply from time to time. Motor is started in synchronous mode. While motor is running, rotational emf is induced in its armature winding coils which speeds up change-over processes of comparators. Motor is switched over to position commutation mode. In speed control mode, control signal applied to additional input of frequency changer is varied depending on load. Integrators connected across inputs of comparators maintain balanced operation of comparators at different control currents relative to rotational emf. EFFECT: reduced pulsations of electromagnetic torque; improved service life of motor.

Abstract: FIELD: medicine; ophthalmology. SUBSTANCE: method for full restoration of eyesight of patients suffering from myopia and astigmatism involves application of a test object. The test object is moved away from the patient's eyes in a stepwise manner. As the test object is moved farther, the patient strains the eye muscles to see the test object elements better. Prior to starting the process, the astigmatism bound is determined. The patient sees the test object clearly and the image is hard when the test object is placed closer than the astigmatism bound, and the image is less contrast when the test object is placed behind this bound. As the test object is moved farther from the astigmatism bound, the patient strains the eye muscle to achieve more clear and contrast vision. The manipulations are repeated until the patient clearly sees a hard image of the test object from a distance of at least 5 m. EFFECT: more effective eyesight restoration.

Abstract: In a known method for producing a cylindrical glass body in a vertical drawing process, a glass blank is softened in a heating zone and drawn off as a glass strand by means of a draw-off device at a controlled drawing speed, the draw-off device comprising a first draw-off unit with rolling bodies rolling on the glass strand and being distributed around the circumference thereof, the rolling bodies being formed by a reference rolling body and at least one auxiliary rolling body, the drawing speed being controlled via the speed of the reference rolling body. Starting therefrom, in order to reduce damage to the surface of the glass strand caused by the draw-off device and to avoid deformations caused by existing bends of the glass strand, it is suggested according to the invention that a value for the torque of the reference rolling body (3) should be determined in dependence upon the weight of the drawn-off glass strand (5), and that the determined value should be used as a setpoint torque for setting the torque in the at least one auxiliary rolling body (4; 7; 8).

Title: Method and apparatus for the production of nitrogen trifluoride
Inventor: SATCHELL DONALD PRENTICE JR
IPC: C01B21/083
Filed: 2003-02-07
Abstract: The invention provides a method and apparatus for producing nitrogen trifluoride. The invention involves passing a working fluid through a heat engine cycle and using the mechanical energy generated by the working fluid to produce sufficient mixing intensity within a nitrogen trifluoride reactor. The method utilizes a working fluid vapor jet, such as a hydrogen fluoride vapor jet, to impart sufficient energy to the mixing zone of a reactor in order to disperse gaseous fluorine within a liquid ammonium acid fluoride melt. A gaseous reaction product stream is removed from the reactor, the reaction product stream comprising nitrogen trifluoride and a working fluid vapor. The working fluid is then separated from the nitrogen trifluoride and recycled for reuse in the process, thereby completing a heat engine cycle.

Title: Sampling clock compensation device of multi-carrier system and method thereof
Inventor: LIOU DE-JENG
IPC: H04L27/26
Filed: 2003-03-21
Abstract: The invention provides sampling clock compensation device of multi-carrier system and method thereof, which utilize the phase difference of the frequency response estimation values in two consecutive symbols of the system's subchannel to estimate the sampling frequency shift between the receiving end and the transmitting end of system. Further compensate the accumulated clock shift and phase rotation of the received signal at the receiving end due to the sampling frequency shift. When the accumulated clock shift is not large, the compensation device employs a phase rotation device to compensate the corresponding accumulated phase rotation in frequency domain. When the accumulated clock shift is too large, the compensation device corrects a specific sampling clock shift in time domain on the one hand and uses the phase rotation device to compensate the corresponding phase rotation of the remaining clock shift in frequency domain on the other hand. Among them, the correction of the specific sampling clock shift is achieved by adjusting the generator generating the clock required for sampling or removing prestage device with a clock controller in the compensation device.
