Abstract: A heat transfer element basket assembly for a rotary regenerative heat exchanger having a splitter plate or stiffening member mounted between the heat transfer plates at a position intermediate between the inner and outer ends of the basket. The stiffening member includes elongated slots adjacent the top surface which accommodate lifting lugs. Elongated slots and lifting lugs also may be included adjacent the bottom surface of the basket. These lugs slide up and down within the elongated slots to an extended position partially above the surface of the basket when in the lifting mode and to a retracted position fullybelow the surface when not in use. Since the lugs are retracted when the basket has been placed in the rotor, they will not interfere with the vertically adjacent baskets. This means that the baskets have a low profile and can be tightly packed in the rotor.

Title: Method of matching stereo images and method of measuring disparity between these images
Inventor: ONDA KATSUMASA
IPC: H04N13/00
Filed: 1996-04-19
Granted: 2000-02-08
Abstract: In the image pickup phase (A), right and left images are taken in through two image-pickup devices (S101, S102). Then, in the next feature extraction phase (B), right and left images are respectively subjected  to  feature  extraction  (S103,  S104).          Thereafter, in the succeeding matching phase (C), the extracted features of right and left images are compared to check how they match with each other (step S105).  More specifically, in the matching phase (C), a one-dimensional window is set, this one-dimensional window is shifted along the left image in accordance with a predetermined scanning rule so as to successively set overlapped one-dimensional windows, and a matching operation is performed by comparing the image features within one window and corresponding image features on the right image. Subsequently, in the disparity determination phase (D),  the left image is dissected  or  divided  into  plural  blocks  each  having  a predetermined size, a histogram in each block is created from disparities obtained by the matching operation based on one-dimensional windows involving pixels of a concerned block, and a specific disparity just corresponding to the peak of thus obtained  histogram  is  identified  as  a  valid  disparity representing the concerned block (S106).

Abstract: A treatment method for removing acid gases by contacting a sour gas stream with a solvent (e.g., an organic amine) which absorbs H2S in preference to CO2 and hydrocarbons. The rich solvent is then regenerated by selectively separating the absorbed hydrocarbons in a first flash tank, a large portion of the CO2 in a high-temperature, low-pressure second flash tank, and substantially all of the remaining acid gases in a high-temperature, low-pressure stripper. The regenerated solvent is recycled and the recovered acid gases; are processed to recover sulphur from the H2S. The CO2 recovered from the second tank is contacted with a second solvent to provide high-quality CO2.

Abstract: An apparatus and method for controlling the operation of (HVAC) equipment (80) or other climate control equipment (560). A user can set a user set point (150). The system (20) determines whether the space is occupied at any given time, and if it is, maintains the temperature at the user set point (270) within a predetermined allowed margin. If the space is not occupied (280) and the temperature drifts outside the allowed margin, then tile system allows the temperature to drift to a maximum allowable margin, or to a newly determined margin, whichever is less (290). The newly determined margin is based upon a determination of the maximum temperature margin to which the system can drift and still drive the temperature back substantially to the user set point within a predetermined maximum recovery time. The recovery time is calculated based upon past temperature-vs.-time data stored for previous cycles of drift and drive (320).

Title: Optical sources having a strongly scattering gain medium providing laser-like action
Inventor: LAWANDY NABIL M
IPC: G01N21/64
Filed: 1995-03-06
Granted: 2005-01-04
Abstract: A gain medium is comprised of a multi-phase system wherein: a first phase is an electromagnetic radiation emission phase; a second phase is an electromagnetic radiation scattering phase; and a third phase is a transparent matrix phase. By example, the emission phase may consist of dye molecules, the scattering phase may consist of high contrast particles, and the matrix phase may consist of a solvent such as methanol. In some embodiments of this invention the emission and scattering phases may be the same phase, as when semiconductor particles are employed. A smallest dimension of a body comprised of the gain medium may be less than a scattering length associated with the scattering phase. It is shown that nearly thresholdless laser behavior is observed in strongly scattering optically pumped dye-methanol solutions containing colloidal TiO2 or Al2O3 ruby nanoparticles. The emission from the high gain colloid exhibits a slope change in the linear input-output characteristics above a critical pump pulse energy. The change in slope is accompanied by a spectral line narrowing with a bichromatic spectrum appearing at high pump energies.
