Abstract: The invention comprises a method of assembling several DNA units in sequence  in a DNA construct and all derivatives of this method. In particular the production of synthetic enzymes is contemplated. Each DNA unit is provided with the same restriction enzyme recognition site at its 5' and 3' ends. The  restriction recognition site at its 3' end being combined with a recognition  site for a DNA modification enzyme. A DNA construct having the same or a compatible accessible restriction site, as provided in the DNA unit, is cleaved at the restriction site by the appropriate restriction enzyme. The desired DNA unit is then inserted into the DNA construct, this ligated produ ct subsequently being brought into contact with a DNA modification enzyme such that the restriction site at the 3' end of the inserted DNA unit is abolishe d. The ligated product is then cleaved at the remaining unmodified restriction recognition site and a subsequent DNA unit is inserted. This process is repeated introducing each desired DNA unit to give a DNA construct containin g all the desired units in sequence.

Title: A drive apparatus for a grab device
Inventor: SCHIERHOLZ MANFRED
IPC: E02F3/42
Filed: 2002-04-02
Abstract: A drive apparatus for a grab device comprising two grab arms, which can be moved like pincers, preferably for a two bucket grab, consists of two hydraulic pivot motors whose shaft journals of the pivot shaft projecting over the motor housing carry the grab arms. Each of the pivot motors has a cylindrical tube piece which is provided at its inner wall with a section which is provided with an internal thread and which is in engagement with a section of the pivot shaft provided with an external thread. The tube piece is a ring piston axially displaceable within but held non-rotatably in a cylinder space formed in one of the housings. The pitch of the threads is so large that the ring piston is able to give the pivot shafts the required torque by its axial displacement. The displacement path of the ring piston between the two annular cylinder chambers, which are alternatively high and low pressure chambers which can be loaded with hydraulic oil, corresponds to the desired pivot angle of the two buckets.

Title: Processes for preparing hydrophobic inorganic oxide pigments
Inventor: EL-SHOUBARY MODASSER
IPC: C09C3/12
Filed: 2000-11-10
Abstract: The present invention provides a treatment method for rendering inorganic oxide particles, such as TiO2 pigment, hydrophobic by predispersing a suitably reactive organohalosilane into an aqueous media, using intensive mixing means (such as a rotor stator emulsifier or inline static mixer) to form a reactive dispersion.  When this dispersion is combined with inorganic oxide particles, such as TiO2 pigment, under sufficient agitation, a hydrophobic inorganic oxide can be formed. The oxides formed by the present invention have good mechanical properties, such as dispersibility in nonpolar substance (i.e., plastics), and they do not degrade physical properties of the pigmented nonpolar substance, such as lacing resistance of thermoplastics.

Title: Inducible site-specific recombination for the activation and removal of transgenes in transgenic plants
Inventor: ZUO JIANRU
IPC: C12N15/82
Filed: 2000-11-13
Abstract: Disclosed is an inducible promoter system in conjunction with a site-specific recombination system which allows (i) specific activation of transgenes at specific times or (ii) excision and removal of transgenes (e.g., antibiotic resistance markers) from transgenic plants. These "suicide" gene cassettes, including the recombination system itself, can be evicted from the plant genome once their function has been exerted. The system is based on the ability to temporally and spatially induce the expression of CRE recombinase which then binds to directly repeated lox sites flanking the transgene in question leading to the precise excision of the gene cassette. Also disclosed is a method to activate an inverted, and therefore silent, transgene by placing two lox sites in opposite orientations flanking the transgene. This results in inversion of the intervening DNA fragment in the presence of CRE  recombinase. This activation can be timed by placing the CRE recombinase under the control of an inducible promoter.

Patent CA-2395146-A1 (CA)
Inventor: BRENNEMAN RODNEY A
IPC: A61B17/00
Filed: 2000-12-07
Abstract: A medical device (20) has a spring made up of a plurality of elongate members (42) in substantial juxtaposition so as to be substantially parallel. The spring is alternately deployed and stowed in use of the device (20), and has a relaxed state and a stressed state. The spring may be arcuate in its relaxed and deployed state and be generally linear in its stressed and stowed state.  The elongate members may be configured so that each contributes to the overall bending strength of the spring but none are stressed beyond its respective yield stress in the stressed state of the spring. The elongate members may be flat in cross-section and together define a laminated structure. One of the elongate members (204a) may terminate short of a distal tip (206) of the spring so that it is more flexible at the tip (206) than at a proximal base (210). The device (20) may be a heart massager with plurality of springs deployed from the end of a tubular cannula to combine to form an inverted umbrella-shape with a fabric (44) stretched over the assembly. The material of the elongate members may be Nitinol and the maximum stress imposed on each is less than that which would induce a martensitic phase change.
