Abstract: A tapered adaptor (10) disposed at a free, leading end of a cultivator shank (S) is arranged to co-operate with a blocking member (27). The blocking member (27) defines forwardly facing abutment surfaces (28, 29). They engage a rear edge portion (54) of the socket (46) of a sweep when the sweep is subjected to a hard impact which would otherwise force the socket beyond the position required for a firm wedging frictional grip with the adaptor (10). Thus, the undesired displacement excessively beyond the required grip position is prevented to enable removal of the socket (46) on exchange of the sweep by a hammer blow. A retainer pin (32) is resiliently held in a transverse groove(31) by the nose (35, 36) of a pair of flat springs. Thus the free movement which might result in loss of the pin 32 is prevented while allowing relatively easy withdrawal of the pin when the sweep is to be knocked off the adaptor. Several alternative embodiments are mentioned. The preferred taper of the adaptor (10) and thus of the sleeve (46) amounts to an included angle of about 2°.

Title: Casing assembly for desiccant element housing
Inventor: MITSCH MATTHEW D
IPC: B01D53/26
Filed: 1997-05-09
Granted: 2000-11-07
Abstract: A casing assembly of a desiccant housing houses desiccant in an air dryer system.   The casing assembly includes a casing portion, a retainer, two porous plates, and a mechanism for compacting the desiccant.  The casing portion defines a channel between two sleeves that channels moisture-bearing air from an inlet of a head end out a tail end of the casing portion.  An inner sleeve defines a flow chamber between the ends.  The head end features an inner seat face that seals against an inner sealing flange of a main portion of the housing.  The head end features an outer seat face that connects to an outer sealing flange of the main portion.   The inlet communicates with a supply port of the main portion from which the moisture-bearing air is received during a drying mode of operation of the system.  An outlet of the head end communicates with a delivery port of the main portion out of which dried air is directed during the drying mode.   The retainer affixes to the inner sleeve within the flow chamber at the head end.   One plate abuts an interior side of the retainer within the flow chamber.          The other plate is slidably disposed within the flow chamber near the tail end.  The compacting means connects to an inner face  of  the  tail  end  and abuts  the  other  plate  thereby compacting the desiccant between the porous plates.  The tail end features an outer seat face that connects to a cover portion of the housing.

Title: Application of glucose transport mutants for production of aromatic pathway compounds
Inventor: MEJIA NOEMI
IPC: C12N15/09
Filed: 1996-05-03
Granted: 2009-03-17
Abstract: This invention describes methods for enhancing carbon flow into a pathway of a host cell to enhance the biosynthetic production of compounds therefrom, the host cells being selected based on being phenotypically Pts-/glucose+. Such host cells are capable of transporting glucose without consuming PEP, resulting in conservation of PEP which can be re-directed into the pathway in order to enhance the production of desired compounds along the pathway. Pts-/glucose+ mutants have been shown to be advantageous for the enhanced production of the aromatic amino acids.

Abstract: The present invention relates to a flexible abrasive article for grinding or polishing and a method for making the same. The flexible abrasive article has a fabric substrate and at least one abrasive layer provided thereon. The abrasive layer is a composite with an adhesive binder in which diamond particles and metal particles are distributed to form an interpenetrating array of diamond particles and metal particles.  It is preferred that the metal particles be about equal to or coarser than the size of the diamond particles.  It is still further preferred that the abrasive layer include a distribution of non-metallic filler particles interspersed with the diamond particles and the metal particles.  The method of making the flexible abrasive article described above can be accomplished by selecting a fabric substrate, preparing an abrasive coating mixture by first mixing a resin with a volatile carrier, second mixing in the particulate components, and applying the mixture to the substrate in one or more layers.
