 Appl.No PCT/RU1996/000125 Applicant NAUCHNO-PROIZVODSTVENNOE OBIEDINENIE TEKHNOMASH Inventor BESCHEKOV, Vladimir Glebovich
This method for the compression working of materials envisages the installation of a blank on a support with the possibility of regulated but limited alternating rotations in a direction similar to that in which the blank is rolled by a punch; the additional formation of end residue on the support of a spherical cavity; and then, while preserving the static contact between the ends of the blank and the punch and support, the end of the blank is simultaneously compressed on the side facing the punch, and on the side facing the support impulses are applied with varying intensity and with a frequency which increases to resonance level, the autoresonant effect being maintained throughout the process. For the purposes of its implementation, the device is provided with a planetary deforming and fluctuating support, in the internal cavity of which a hollow gravitational resonator is placed in fluid, and a relaxation unit for elastic tension.

 Appl.No PCT/US1996/006157 Applicant MEASUREX CORPORATION Inventor CHASE, Lee, M.
An on-line laser triangulation position sensing system provides measurements of the surface features of a moving sheet such as paper. The measurements are correlatable with measurements made with standard laboratory surface smoothness testers and provide predictions of the printability of paper during its fabrication. The sensing system includes a segmented balance detector having a high frequency response. The sensing system further includes signal processing circuitry comprising a plurality of channels, each channel including a filter. The various filters have different cutoff frequencies for passing different frequency spectra representing ranges of surface feature scale sizes. The cutoff frequency of each filter is varied in response to variations in sheet speed. The sheet sensing system further includes a sheet stabilizer to minimize flutter in the measurement region and a standardizing member permitting performance verification of the sensor system at at least one scale size spectrum. The sensing system may also be provided with a sheet compressor to compress the sheet in the measurement region so as to simulate the pressures applied to sheet samples by laboratory air leak smoothness testers. The output of the position sensing system may be used in conjunction with various kinds of papermaking machines to control one or more of the many papermaking process parameters that determine the smoothness or texture of the final product. The sensing system can be used to measure tissue crepe and such measurement can be utilized to control various crepe-determining stages in a tissue making machine and to monitor the condition of the creping or doctor blade in such a machine.

The invention concerns an accumulator-powered lawn-mower in which the battery (10) feeding the electric motor is accommodated in a battery housing which can be inserted into a battery shaft (28) in the lawn-mower chassis. For charging purposes, the battery can be removed from the shaft, the charging apparatus comprising a corresponding shaft with contacting means. At the top, the battery housing has a handle (12) which can pivot about a horizontal spindle (16) and is coupled to locking means (22) which engage in corresponding interlocking recesses (24) when the handle is folded down. The battery is supported at the bottom of the shaft, preferably via springs (30). The contact system is independent of the mechanical attachment and comprises on the battery housing contact lugs (32) which extend in the longitudinal direction of the shaft and co-operate with contact springs (34) on the shaft which are supported by helical compression springs (36) in order to increase contact pressure.

 Appl.No PCT/SE2000/001243 Applicant KVAERNER PULPING AB Inventor TIBBLING, Petter
The present invention relates to a process and a device for the oxygen delignification of cellulose pulp suspensions giving improved kappa reduction. According to the process in accordance to the invention, the return liquor (40) which is recovered from a displacement or washing device (20) after an oxygen stage (/17) is subjected to wet oxidation under pressure (30). The wet oxidation process is accelerated by the liquor being pressurized in an oxygen-containing media and preferably at an elevated temperature. The wet-oxidized return liquor is supplied to the cellulose pulp such that the wet-oxidized return liquor constitutes the bulk of the liquid part of the cellulose pulp suspension before the latter is conducted to an oxygen delignification stage. Sodium hydroxide is also supplied (35) in a quantity which is such that the oxygen delignification can take place in a buffered medium such that the pH is kept essentially constant during the whole of the oxygen delignification. The invention provides an optimum kappa reduction at minimum cost.

This invention concerns a method for catalytic hydrogenation of aromatic nitrocompounds to aromatic amines by applying a supercritical or near-critical state solvent. The aromatic nitro compound, hydrogen gas and the solvent are mixed together under elevated pressure and temperature, so that a homogenous mixture which is in supercritical or near-critical state is formed. The resulting mixture is brought into contact with the catalyst and the reaction product is formed. The method has applicability to industrial processes for producing aromatic amines.

 Appl.No PCT/US1997/019694 Applicant BELOIT TECHNOLOGIES, INC. Inventor WEDEL, Gregory
A dryer section employs top-felted and bottom-felted dryer sections, each comprised of a single steam-heated drying cylinder with a diameter of about 12 feet. The web is transferred between drying cylinders by a two vacuum roll transfer without an open draw. The dryer fabric wrap on the large dryer cylinders is over 270 degrees resulting in large drying capability per dryer roll. Because each large dryer is followed by another large dryer roll which dries the opposite side of the web, uniformity of drying is maintained. Each dryer cylinder may have its own dryer fabric stretcher and guides. Alternatively, individual dryer fabrics service multiple top-felted dryers and bottom-felted dryers, respectively. The web is constrained approximately 96 percent of the time as it passes through the dryer section. The dryer section can achieve 2.9 inches of dryer surface in the machine direction for every inch of dryer section.

 Appl.No PCT/JP1996/001821 Applicant MATSUSHITA ELECTRIC INDUSTRIAL CO., LTD. Inventor YAMAMOTO, Tamotsu
An operation type electronic component which is used for a remote controller of various electronic equipment and portable electronic equipment and is equipped with a push switch driven by the rotating or push operation of an operation knob. The component can be reduced in size by a simple construction and can be grounded by merely fitting. A dome-like movable contact (23E) is put on fixed contacts (23A, 23B) disposed on a fitting substrate (22) to form a switch unit (23). An L-shaped actuator (24) is interposed between this switch unit (23) and a driving body (21) so that the driving body (21) returns to the original state after the push operation of an operation knob (6) by the elastic operation force of the dome-like movable contact (23E) of the switch unit (23). Further, a metal plate (25) equipped integrally with a live current portion (10) and a conductor of an earth portion (26) is fixed by insert-molding to the resin fitting substrate (22) and is electrically isolated so as to interpose a lightning conductor portion (26A) of the earth portion (26) between the live current portion (10) and the operation knob (6). According to this construction, the number of constituent components can be reduced, the overall size can be reduced, too, and static electricity occurring in the operation knob (6) can be always conducted to the earth.

 Appl.No PCT/EP1996/001111 Applicant EMSA-WERKE WULF GMBH & CO. Inventor HORSTMANN, Klaus
In a flask (1) for liquids, in particular an insulating flask, a pouring aperture (6) can be closed by means of a lid (9) which can be releasably attached to the flask. The lid is provided with a spring-loaded closure element (15) which can be moved by means of a handle (29) into a closed position. The closure element can move in a substantially vertical opening motion between an open position, in which the pouring aperture is clear, and the closure position, in which it closes off the pouring aperture. In order to ensure that the mechanism for moving the closure element is uncomplicated and durable and, when operated, ensures easy opening and effective closure of the pouring aperture, the spring element is formed from a spring-elastic diaphragm (16) connecting the closure element to the lid.
