Patent CA-1318240-C (CA)
Title: Device for saturating a liquid with gas
Inventor: DAMANN FRANZ-JOSEF
IPC: B01F3/04
Filed: 1988-07-04
Granted: 1993-05-25
Abstract: Abstract:     The invention relates to a device suitable for saturating a liquid with a gas.  The gas is pumped through an injector plate situated on top of a reaction pressure chamber, in which the saturation reaction occurs, the reaction chamber being located inside a reaction vessel.  A pump, which is controlled by sensors actuated by two liquid levels in the reaction pressure chamber, is connected through a reversing valve to either an inlet tube for fresh liquid or to the outlet of the reactor vessel to which a tank is also connected.  The gas-saturated liquid is eventually removed from a tank through a flow control valve.  The pump motor is controlled by sensors for the purpose of replenishing the liquid and by a timing arrangement for the purpose of circulating the liquid.  In this way, the pump pressure during replenishment of the liquid can be made lower than that during the recirculation of the liquid, and energy can consequently be saved.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus for automatically adjusting the focus of cathode ray tubes which can be utilized with cathode ray tubes used as monitors or for television sets that are operated with different field freguencles and different number of scan lines.  A specific image such as a fine checkerboard pattern or a fine line pattern is produced on the monitor which is to be adjusted and the image is then picked up with a solid state camera; the image magnification and resolution are selected such that the fine pattern is acquired with full resolution  in  the  camera  signal.   The  camera  signal  is evaluated using a known image processing system and the image focus of the image acquired by the camera is calculated by using histogram calculations.   The width of the histogram curve is a measure of the image focus and the image focus is either manually or automatically adjusted.

Abstract: A device for removing irregularities in or enlarging a buried duct comprises a cylindrical housing corresponding approximately in diameter to the required diameter of the duct, an expandable shell comprising a plurality of tapered leaf members pivotally attached at their rear ends to the front of the housing, and remotely controllable drive means for moving the leaf members between contracted and expanded configurations. In operation, the apparatus is drawn through the duct with the leaf members in a contracted configuration in which they enter a portion of the duct of a diameter less than the required diameter. The drive means is operated to force the leaf members outwardly against the sides of the duct to expand the duct. The leaf members are then retracted and the apparatus is drawn forward. The apparatus is particularly intended for preparing damaged sewers prior to fitting an inner, lining pipe. By forming the shell in two sections, of which the nose is cylindrical in the contracted configuration and conical in the expanded configuration, the apparatus can move forward a distance approximately equal to the length of the leaf members with each expansion and contraction cycle, a continuous tension being applied to the chain drawing the device forward.

Abstract: A method and apparatus for photon scanning tunneling microscopy for examining a sample in a sample area on a surface at a subwavelength resolution is disclosed. The method comprises generating a near-field of photons at a surface containing a sample area. The near-field has an area that is larger than the sample area, and the near-field has an exponentially increasing intensity in a direction perpendicular to and towards the surface. The near-field is sampled with a probe which receives photons from that near-field that tunnel from the surface to the probe. The received photons are detected and a detector produces an output signal that is proportional to the number of photons received by the probe. The sample area is scanned with the probe in at least one direction parallel to the surface. While scanning, the probe may be maintained either at a position of a constant near-field intensity or at a position of constant distance from the surface. A photon scanning tunneling microscope for using the method is also disclosed.
