Filed: 1980-10-14
Abstract: PURPOSE:To provide a catalyst reactor of superior durability against abrasion by dust in gases in particularly by inclining plate-like catalysts slightly in a gas flow direction, and constituting the surfaces of the catalyst plates facing the upper stream side of the gas of an abrasion resistant material and the surfaces facing the down stream side of a catalytic material, respectively. CONSTITUTION:Catalyst plates 5 provided in a catalyst reactor 4 are inclined by an angle theta with respect to a gas flow direction 6. The surfaces 7 of the catalyst plates facing the upper stream side of gas are constituted of an abrasion resistant material such as metal and the surfaces 8 facing the down stream side of gas of a catalytic material. The above-described angle theta is preferably in a 5-15 deg. range. Plural steps of said plate-like catalysts are disposed so as to have the planes of inclinations alternately in opposite directions. As a result, the dust entrained in the gas is collided against only the surfaces 7 of the abrasion resistant material of the catalysts 5 and the surfaces 8 of the catalyst material position behind the same and therefore, the collision of the dust against the latter is reduced, and the abrasion of the catalysts is prevented. Hence, for example, in denitration of waste gases, the catalysts are usable as well with high velocity of gas of about 10m/s. Here, 1 in the figure denotes a boiler.

Title: Electric and pneumatic regulator
Inventor: AANORUTO MAN
IPC: F02D11/06
Filed: 1989-06-07
Abstract: PURPOSE: To prevent increase in control force necessary for operation by selectively opening a low pressure connection and an atmospheric pressure connection by a valve body acted on by a spring, and providing excitation current of a magnetic coil as control variable for the position of a throttle valve. CONSTITUTION: A chamber 50 communicates with an atmospheric pressure connection 24. A diaphragm 42 is moved upward by a spring 44 under high pressure. A valve body 120 is moved upward by a predetermined current. The pressure connection 24 is closed, a low pressure connection 28 is open and a chamber 52 is under low pressure. The pressure in the chamber 50 is decreased by a gap 154 and through holes 156, 152. The diaphragm is moved downward, and the valve body is in an intermediate position. When control current is increased to some extent when the valve body is in the intermediate position, the valve body 120 is elevated, however the diaphragm moves the valve body to the intermediate position again. When the control current is decreased to some extent, the valve body 120 is moved downward, however the valve body 120 is returned to the intermediate position again.  Thus, as the control current not only regulates the valve body, but also the diaphragm 42, the regulation of a control valve 8 can be effected correctly.

Filed: 1975-12-04
Abstract: An apparatus for the periodic transverse welding and severing of longitudinally advanced superposed wrapper sheets has two oppositely rotating, cooperating welding shoes, at least one of which is provided with a heater and at least one of which is displaced towards its rotary axis by virtue of the engagement between the welding shoes during each revolution thereof. One welding shoe has a tapered terminal head which includes leading and trailing flanks as well as a cutting edge. The other welding shoe has a counterface cooperating with the cutting edge and two elastic, rod-like members arranged adjacent and parallel to the counterface. As the welding shoes simultaneously engage the superposed wrapper sheets from opposite sides, the leading flank of the tapered head, cooperating with one of the elastic rod-like members pinches the wrapper sheets and provides a first transverse weld seam. Thereafter, the cutting knife, cooperating with the counterface, severs the sheets adjacent and parallel to the first weld seam. Subsequently, the trailing flank of the tapered head, cooperating with the other elastic rod-like member, pinches the wrapper sheets and provides a second transverse weld seam adjacent and parallel to the transverse cut.

IPC: G02F1/133
Filed: 1988-06-13
Abstract: PURPOSE:To make a black-and-white display only by electric field application by laminating a driving cell wherein liquid crystal molecules are twisted by a specific angle and a compensating cell wherein liquid crystal molecules are twisted in the opposite direction from said driving cell. CONSTITUTION:Light which is made incident on the panel from outside as shown by an arrow A is polarized by a 1st polarizer 1 into linear polarized light. Here, an emergency select voltage is applied to a picture element position at an intersection of matrix electrodes that the driving cell 2 has. At this time, the liquid crystal molecules in the driving cell 2 are twisted and the linear polarized light 101 becomes elliptic polarized light 103. In this case, the axis D of polarization of the 1st polarizer 1 is arranged turning clockwise at 45 deg. to an X axis and the axis E of polarization of a 2nd polarizer 4 has its direction of polarization counterclockwise at 90 deg. to the X axis. Thus, the two-layered structure of the driving cell and compensating cell which are opposite in twist direction and different in twist angle is employed, so the black-and-white display can be made only by applying an electric field to the driving cell.
