Title: Conductivity log for boreholes
Inventor: RORDEN LOUIS H
IPC: G01V3/26
Filed: 1991-09-09
Abstract: CONDUCTIVITY LOG FOR BOREHOLES                    Inventor: Louis H. RORDEN      Abstract A method and apparatus is described for measuring the resistivity of a formation adjacent a borehole.  It relies on a modified induction approach and preferably is incorporated into a metal drill collar for MWD measurements.  Directional nulls are created in a primary changing magnetic field formed in a formation by a transmitting antenna which is in a groove on the surface of the drilling collar. Detecting antennas are placed at the directional nulls to enable the primary magnetic field to be distinguished from the secondary field caused by the current induced in the formation by such primary field.  The drill collar also carries a plurality of current detectors which detect the value of current which is induced in the formation to provide a resistivity profile immediately adjacent the borehole.  The preferred embodiment described uses a hybrid modified induction and electrical approach.

Patent CA-2060572-A1 (CA)
Title: System and method for electromagnetically determining both the proximityand dimensions of a non-conductive structure
Inventor: CLARK WILLIAM G JR
IPC: G01B7/00
Filed: 1992-02-03
Abstract: W.E. 56,609 ABSTRACT OF THE DISCLOSURE Both a system and a method are provided which allows an eddy current probe to accurately determine both the proximity and dimensions of non-conductive structures which are normally invisible to such probes. The system comprises a portable target medium that is movable into a known position with respect to the non-conductive structure, and that includes a conductive material that couples strongly with a fluctuating magnetic field, and a movable eddy current probe that emanates a fluctuating magnetic field and which generates a signal indicative of the magnitude of the interaction between the field and the portable target medium from which the distance between the two may be computed.  The system may be used to determine the proximity of non-conductive structures such as plastic pipes that have been buried under ground, as well as the dimensions of such non conductive structures.  When the system is applied to measure the dimensions of such a structure, the portable target medium assumes a form that is flexibly conformable to one of the walls of the structure and which is placed in abutting relationship thereto.  The eddy current probe is then scanned against an opposing wall of the structure, whereby the width of the structure may be computed by measuring the strength of the interaction between the probe and the medium.  In addition to measuring the dimensions of non-conductive structures, the system may be used to measure the dimensions of non-magnetic structures when the target medium includes a strongly magnetic material.

Title: Clamping device for releasably connecting two profiled parts
Inventor: ZUELLIG KURT
IPC: F16B12/20
Filed: 1992-02-24
Abstract: This clamping device is intended for releasably connecting two profiled parts (1,19). One of the profiled parts (1) is arran-ged so that an insert core (2) can be inserted and fixed in it.      The core (2) has an axially movable bolt (7) having an end portion which comprises a projection (21) intended to be intro-duced in a slot of a second profiled part (19) in order to exert a force against an area of a portion of said second pro-filed part (19) partially covering said opening. A screw recei-ved in a threaded bush (4) engages the bolt (7) by means of a system of sliding surfaces (14,15) in order to displace the bolt crucially. The bolt (7) has supporting means (27,28) for pivotally supporting holding pieces (17,17'). Said holding pieces and the interior walls of the insert core (2) have a second system of sliding surfaces (24,26) which owing to the axial movement of the bolt (7) cause a deviation of the holding pieces (17) having in its free end area said projection (21) intended to exert said force. Preferably, the thread of the screw (5) and the threaded bush (4) have a pitch of more than 1 mm per revolution, and preferably, the bolt (7) is led through a laterally expanded transverse hole of a threaded bush (4), and a transverse bore of the insert core (2) and the threaded bush (4) guided in it are designed in such a form-locking way that a lateral displacement of the threaded bush (4) along the transverse bore of the insert core (2) is possible.
Patent CA-2062178-A1 (CA)
Title: Aerosol beam microinjector
Inventor: METS LAURENS J
IPC: C12N15/87
Filed: 1992-01-10
Abstract: ABSTRACT OF THE DISCLOSURE     The present invention uses aerosol beam technology to accelerate either wet or dry aerosol particles to speeds enabling the particles to penetrate living cells.  Aerosol particles suspended in an inert gas are accelerated to a very high velocity during the jet expansion of the gas as it passes from a region of higher gas pressure to a region of lower has pressure through a small orifice.  The accelerated particles are positioned to impact a preferred target, for example, a plant or animal cell or bacterial culture.  When the droplets include DNA or other macromolecules, the macromolecules are introduced into the cells.  The particles are constructed as droplets of a sufficiently small size so that the cells survive the penetration.  Once introduced into the target cell the macromolecules can elicit biological effects.  Because the method of introduction is a physical one, the biological barriers that restrict the application of other DNA transfer methods to a few plant species and a few cell types are not present.  In addition, the method and apparatus of the present invention permit the treatment of a large number of cells in the course of any single treatment. Thus the inventive method and apparatus should be applicable to a wide range of plant species and cell types that have proved in the past to be quite impervious to standard methods of genetic engineering.

IPC: C12R1/19
Filed: 1991-07-10
Abstract: 2086936 9201047 PCTABS00010 A member of a specific binding pair (sbp) is identified by expressing DNA encoding a genetically diverse population of such sbp members in recombinant host cells in which the sbp members are displayed in functional form at the surface of a secreted recombinant genetic display package (rgdp) containing DNA encoding the sbp member or a polypeptide component thereof, by virtue of the sbp member or a polypeptide component thereof being expressed as a fusion with a capsid component of the rgdp. The displayed sbps may be selected by affinity with a complementary sbp member, and the DNA recovered from selected rgdps for expression of the selected sbp members. Antibody sbp members may be thus obtained, with the different chains thereof expressed, one fused to the capsid component and the other in free form for association with the fusion partner polypeptide. A phagemid may be used as an expression vector, with said capsid fusion helping to package the phagemid DNA. Using this method libraries of DNA encoding respective chains of such multimeric sbp members may be combined, thereby obtaining a much greater genetic diversity in the sbp members than could easily be obtained by conventional methods.
