Abstract: A vortex tube gas cleaning device 10 is used to clean a particle containing gas flow stream of particles. The device 10 has an outer tube 12 having an inlet 14 at an upstream end, and, in series downstream of the inlet 14, a vortex generator 16 in a vortex region 18, and a separation region 19. An inner extraction tube 40 is located at the downstream end of the tube 12 and extends concentrically within the outer tube 12, upstream, canti-lever fashion. A peripheral outlet region 22 is defined annularly around the inner tube 40 downstream of the separation region 19 and leads to an outlet port 36. A central outlet region 24 is defined within the inner tube 40 downstream of the separation region 19 and leads to an outlet 48. A ring 50 which is integral with the inner tube 40 extends into the outer peripheral region 22. It has an oblique leading wall 52 leading to a crown defining an annular orifice 54. The wall 52 forms an acceleration region via which flow in the region 22 is accelerated toward the annular orifice 54. The wall 52 commences spatially downstream of a leading edge of an inlet 42 into the tube 40. The leading edge blends into an aerodynamic lip 43.

Abstract: The process comprises three stages, namely an oxygen bleach which is optionally combined with a hydrogen peroxide bleach (EOP stage), an ozone bleach (Z stage) and a peroxide bleach (P stage). According to the invention, the residual oxygen content of the exit air from the Z stage is completely reacted in the EOP stage, and the effluent of the Z stage is used for dilution between the EOP and Z stages and/or for ash removal from the pulp after bleaching. It is advantageous in this case to control the temperature, the NaOH supply and the O2/H2O2 ratio in the EOP stage, so that the oxygen consumption at a constant conversion is adjusted to the residual oxygen content of the exit air from the Z stage.

Abstract: PCT No. PCT/NO92/00007 Sec. 371 Date Nov. 3, 1993 Sec. 102(e) Date Nov. 3, 1993 PCT Filed Jan. 17, 1992 PCT Pub. No. WO92/12893 PCT Pub. Date Aug. 6, 1992.The invention relates to a method for loading and discharging tanks (1) for transporting oil, a method for transporting oil in tankers (1) and a pipe and valve system (6, 7, 8) in a tanker (1) for performing the method. According to the invention, gassing of hydrocarbon containing gas during loading and unloading is reduced by loading or unloading the cargo tanks (2) while the oil is maintained in contact with a generally saturated HC gas. This is done by saving the HC gas which is developed during loading or unloading, this gas later being used in further loading and unloading. This is made possible by a pipe and valve system (6, 7, 8) according to the invention. In accordance with one embodiment of the invention, the tanks are filled completely so that the oil is present in tank hatches (10) and risers (11) located at the top of the tanks (2). This results in that the gas volume above the cargo before a possible grounding is approximately equal to zero and, consequently, the necessary underpressure is obtained above the cargo for establishing a hydrostatic balance at the bottom of the tanker (1) with a minimum spill of a cargo.

Granted: 1995-09-05
Abstract: An optical modulation device is constituted by a polarizer; a first film forming a first state and a second state depending on an electric field applied thereto, the first state causing birefringence and the second state not causing birefringence respectively of polarized light from the polarizer, the first film having a thickness set for functioning as a halfwave plate in its first state; and a second film not causing birefringence of light having passed through the second state of the first film but causing birefringence of light having passed through the first state of the first film, the second film having a thickness set for functioning as quarter wave plate or a halfwave plate when the first film is set in its first state.  The light from the second film is caused to enter the second film again through a reflection means or a third film selectively forming a first state causing birefringence of light which has caused birefringence and passed through the second film or a second state not causing birefringence of light which has passed through the second film without causing birefringence.  The light thus modulated is then caused to enter an analyzer.  As a result, an optical modulation giving a large contrast is provided by using a material having a small birefringence effect for the first film or third film.

Abstract: A collapsible container far making and transporting cheese is made with four interlocking wall panels. Each of the panels is molded from a resin material with ribbed construction and with locking elements for engaging adjacent panels. The lacking elements provide mechanical interlocks against relative movements of the panels along two axes that extend normal to the panels and frictional interlocks against relative movements of the panels along a third axis that extends normal to the other two axes. The mechanical interlocks also transmit a preload torque that resists angular diverging movements between the panels about the third axis. The preload torque bows the panels toward an interior space of the container before the container is filled with cheese.
