Patent PT-101144-A (PT)
Inventor: TROKHAN PAUL DENNIS
IPC: D21F11/00
Filed: 1992-12-18
Abstract: Disclosed herein is a cellulosic fibrous structure having multiple regions distinguished from one another by basis weight. The structure is a paper having an essentially continuous high basis weight network, and discrete regions of low basis weight which circumscribe discrete regions of intermediate basis weight. The cellulosic fibers forming the low basis weight regions may be radially oriented relative to the centers of the regions. The paper may be formed by using a forming belt having zones with different flow resistances. The basis weight of a region of the paper is generally inversely proportional to the flow resistance of the zone of the forming belt, upon which such region was formed. The zones of different flow resistances provide for selectively draining a liquid carrier having suspended cellulosic fibers through the different zones of the forming belt.

Abstract: FIELD: copper-nickel branch of nonferrous metallurgy; applicable in processing of copper-nickel sulfide ores. SUBSTANCE: converter slags are processed by teeming them into ladle and subjected to reduction smelting with slag brought in contact with 1-9% of aluminum from the slag mass at 1250-1400 C. According to the offered method, transferred into sulfonated metal is 95-100% of cobalt, i.e., 50x0.95=47.5% which may be melted with converter matte. So, introduction of special deep process of ladle impoverishment of converter slags makes it possible to raise, as compared with the known methods, the recovery of cobalt by 47.5-20=27.5%. With the cobalt content of 0.8% per every 100 t of copper-nickel matte, additional recovery will amount to 100x008x0.275=0.220 t. With the cost of one ton of cobalt of 20 thou.dollars, this will result in 0.22x20=4.4 thou.dollars. It is necessary to add to the above effect, the reduced costs for processing of one unit of converter slag for one operation in ladle (or in mixer-settler) but not in converter or electric furnace, in which instead of slag are processed matte and initial copper-nickel ore. EFFECT: performance of deep impoverishment of converter slags for one operation, higher recovery of cobalt and other valuable metals, more than ten-fold acceleration of impoverishment process as compared with the known process.

Abstract: FIELD: radio engineering. SUBSTANCE: single-frequency radio signal repeater incorporates antenna reception path composed of high-frequency amplifier, frequency converter with heterodyne, intermediate frequency amplifier connected in series, output of the latter is connected through delay line to input of transmission path composed of intermediate frequency amplifier, frequency converter which has same heterodyne as in reception path and power amplifier connected in series. Proposed repeater is distinguished firstly by switching cycle of reception and transmission paths carried out by leading edge of coming radio signal in trigger circuit and by two one-shot multivibrators, one having inverse output; and secondly by addition into it of former of bell-shaped voltage for supply of intermediate frequency amplifier with narrow spectrum of radio channel of transmitter an of two optrons which channels are switched on by voltages from outputs of one- shot multivibrators. Voltage exists across inverse output of one-shot multivibrator in initial position. Antenna is connected to input of operating high-frequency amplifier by channel of optron in reception path. No voltage exists across output of second one-shot multivibrator. That is why intermediate frequency amplifier of transmitter does not operate and output of power amplifier is disconnected from antenna. When radio signal of carrier frequency comes into antenna it fills delay line from output of intermediate frequency amplifier of transmitter and to input of trigger circuit. Pulse from output of trigger circuit simultaneously switches on both-shot multivibrators. One-shot multivibrator having 98 μss inverse output switches off reception path of repeater and second one-shot 64 μss multivibrator switches on transmitter which transmits radio pulse filling delay line. 34 μs after completion of operation of transmitter (98-64=34) reflected radio wave will die down. Circuit or repeater will return to initial position and will again be ready to receive radio signal of carrier frequency. EFFECT: enhanced operational reliability and stability of repeater.

Title: Resonant thermal out-of-plane buckle-beam actuator
Inventor: SINCLAIR MICHAEL J
IPC: H02N10/00
Filed: 2002-12-04
Abstract: An out-of-plane thermal buckle-beam micro electrical mechanical actuator is formed on a planar substrate of semiconductor material (e.g., silicon). The actuator includes first and second anchors secured to the substrate and multiple elongated thermal buckle beams that are secured between the anchors. The buckle beams are formed of semiconductor material, such as polysilicon. In one implementation, the buckling beams are coupled together by a pivot frame that includes a frame base secured to each buckle beam and at least one pivot arm that is coupled to the frame base at one end and includes a free end that pivots out-of-plane when the actuator is activated. A cyclic current source directs cyclic electrical current through the thermal buckle beams via the anchors to impart thermal expansion of the buckle beams and hence a cyclic buckling motion of them out of the plane (i.e., away from) the substrate. In one implementation, the actuator has a characteristic resonant deflection frequency range and the cyclic current is of the first frequency within the resonant deflection frequency range.
