Patent CA-2005550-A1 (CA)
Inventor: SPIES BRIAN R
IPC: G01N17/00
Filed: 1989-12-14
Abstract: A transient electromagnetic method far detecting irregularities on container walls by measuring wall thickness. The method utilizes a transmitting antenna and a separate receiving antenna arranged in a loop-loop configuration. The transmitting antenna induces current into the container wall and the receiving antenna and the receiver detect the decay of the induced current, which is then analyzed to detect wall thickness. A receiving antenna array of many receiving antennas is used to increase the spatial resolution. Simultaneous measurement of the induced current by the receiving antennas reduces noise that is coherent across the array.      Use of a noise antenna located so as to be unaffected by the transmitting antenna further reduces noise. The received signal from the receiving antenna array is displayed on a two-dimensional display in a spatial arrangement that corresponds to the spatial arrangement of the receiving antennas. The display can be scrolled over the time range of the received signals to produce a moving image, so that irregular areas can be more easily detected than with a static display.

Inventor: KUMAR RAVI
IPC: B01D53/047
Filed: 1990-02-12
Abstract: An improved pressure swing adsorption process is disclosed for the recovery of two individual components from a multicomponent gas mixture.  The process utilizes a first group of adsorbent beds selective for the secondary component product and a second group of beds selective for tertiary impurities in the mixture.  The gas mixture is passed through the first and second beds in series and high purity primary component product is discharged from the second beds.  The secondary component product is recovered by desorption from the first beds. Product recovery is improved by recycling depressurization gas from the first beds and by several novel pressure equalization steps.  The process can be used to recover high-purity hydrogen and carbon dioxide from a gas mixture containing these components along with minor amounts of methane, carbon monoxide, and nitrogen.

Title: Automatic follow-up projecting system
Inventor: MIYAMOTO TAKASHI
IPC: G03B21/00
Filed: 1990-09-20
Abstract: ABSTRACT OF THE DISCLOSURE A light (or an infrared ray) emitting member or a reflective (or an infrared ray reflective) medium (something like a reflective tape which reflects light in the caoxial direction when light is applied to it) is mounted at a predetermined position on an object to which an image is projected.  The light emitting member or the reflective medium is caught in the coaxial direction of an image projecting unit by an (infrared ray) image Pick-up means and video signals obtained by the (infrared ray) image pick-up means are binarized in the image processing unit, thereby a high luminous part of the light emitting portion or the reflected portion necessarily coming out on a binary image.  A central value of a primary moment (so called a center of the figure) on the binary image including the high luminous point obtained by the above operation, is calculated on real time, and the calculated data are fed back to an electrically-driven driving portion of the image projecting unit, so that the image may be continually projected at the predetermined position.  The electrically-drive turn table is adapted to automatically control the image projecting direction including the direction of light.  Carrying out a series of the controls described above exactly, the image projecting apparatus projects the image by auto-matically tracking the position of the moving light emitting member or the reflective medium.  Consequently, the image can be continually projected at the predetermined position, automatically tracking the moving object such as an airship or a balloon, so that it can be available as an effective advertizing medium or news medium.
