Patent CA-2024649-A1 (CA)
IPC: G01P3/50
Filed: 1990-09-05
Abstract: ABSTRACT OF THE DISCLOSURE     A system for determining the rotational, or cyclic, speed and rotational position of a looped traveling belt, such as a felt in a papermaking machine, utilizes a discontinuity, or caliper variation, in the surface of the belt near one edge thereof.  A fluid stream, such as compressed air, is projected against the web along the annular area containing the discontinuity, and a pressure transducer is mounted in fixed proximity with the belt downstream of, and aligned with, the fluid stream.  The transducer senses differences in the pressure of the fluid stream projected against the belt and against the discontinuity, and produces a signal indicative of the passage of the discontinuity past the transducer.  The time interval of this signal is used to compute the cyclic speed of the traveling belt and to identify the part of the belt passing through a nipped roll couple at another location.
Patent CA-2028945-A1 (CA)
Inventor: HADDAD JAMES H
IPC: B01J29/90
Filed: 1990-10-30
Abstract: Process for the continuous conversion of light olefin gas feed containing ethene, propene and butene to produce heavier hydrocarbons by contacting the light olefin feed in a fluidized bed reaction zone with a medium pore molecular sieve zeolite catalyst under oligomerization conditions to invert the light olefin feed to heavier hydrocarbons. The catalytic reaction causes the conversion of the light olefins to heavier hydrocarbons, the deposition of coke by-product on the catalyst and the absorption of hydrocarbon product on the catalyst. The deposited coke causes the partial deactivation of the catalyst.      A portion of the partially deactivated catalyst containing deposited coke and absorbed hydrocarbon product is continuously withdrawn from the reaction zone and transferred to a catalyst stripping zone in which the catalyst is contacted with an inert stripping gas to remove the absorbed hydrocarbons from the catalyst. The stripped catalyst containing deposited coke is withdrawn from the stripping zone and transferred to a catalyst regeneration zone in which the catalyst is maintained in a fluidized bed and contacted with an oxygen containing gas to effect combustion of the coke and removal of the coke from the catalyst and regeneration of the catalyst. The regenerated catalyst containing a minor amount of residual carbon is withdrawn from the regeneration zone and introduced to the reaction zone and contacted with fresh light olefin feed. The careful control of the operating conditions in the regeneration zone provides removal of substantially all of the coke deposits at relatively low temperatures and an effluent flue gas with a low carbon monoxide content and low water content.

Title: Blueberry basket harvester
Inventor: FRASER WILLIAM J

Filed: 1991-03-28
Abstract: RECOMMENDED FORMS                          Form 24 (ss. 21, 31, 34 and 142) ABSTRACT The Blueberry Basket Harvester is a free standing manually operated receptacle, castored up to and positioned around the base of the main stock of a mature blueberry bush. The invention is sufficiently wide to provide a catch-area for the fanned overhanging branches of the bush. Once in place, the Harvester operator manually threshes the blueberry branches with a short length of firm hose, causing the fruit to drop onto the fabric apron spanning the frame. Subsequent to threshing the bush, the Harvester is pulled back, a field container is placed beneath the rear of the Harvester, and the flap at the back of the apron is raised to enable the harvested fruit to be scooped out. The fruit is then cleaned and marketed. Powered blueberry harvesters are employed in the industry, but their cost and mechanical complexity limit their use to large harvesting operations. The Blueberry Basket Harvester is distinguished from its mechanized counterpart by its mechanical/maintenance simplicity, manoeuvrability and efficiency.
