Title: Chimeric receptor polypeptides, human h13 proteins and uses thereof
Inventor: YOSHIMOTO TAKAYUKI
IPC: A61K35/00
Filed: 1993-06-11
Abstract: Chimeric receptor polypeptides are disclosed which contain chimeric viral receptors of a first species which bind non-first species specific viruses and/or their envelope protein env binding domains, nucleic acid encoding therefore, cells or tissues ex-pressing the chimeric receptor polypeptide, as well as methods of preparing and using thereof. Also disclosed are methods for rendering eukaryotic cells or tissues selectively susceptible to binding and/or infection by recombinant viral vectors or delivery vectors that bind a chimeric receptor of a chimeric receptor polypeptide expressed in target cells or tissues. Also disclosed are gene therapy methods which may be used on selected cells or tissues of a mammal, bird, insect or yeast through the use of tran-sient or constitutive expression or vector association of a chimeric receptor polypeptide having a chimeric receptor binding site. The resulting chimeric receptor cells or tissues are thus rendered susceptible to infection or binding by viral vectors or env binding domains thereof which specifically bind the chimeric receptor. The chimeric receptor cells are then susceptible to infection and/ or binding by therapeutic and/or diagnostic agents which comprise an env binding domain of a non-first species specific virus capable of binding a chimeric receptor polypeptide of the present invention.

Title: Breakaway clutch
Inventor: SIMOND ALFRED
IPC: F16D3/20
Filed: 1994-12-12
Abstract: The present invention provides a break-away clutch for a robot end-of-arm tooling device for placement between a robot and a tooling device.   The break-away clutch comprises a housing having a forward surface,  a stud member, and a top plate having an underside facing surface.  The housing has one end closed to form a cavity,  The cavity holds a compression spring, and a piston that encapsulated the spring.          The stud member has a ball end at one end resting on the piston and a distal end attached to the end-of-arm tooling device.  The piston moves axially within the cavity and reacts to movement of the stud member.          Notches located on the stud member, and pins located on the underside facing surface of the top plate translate rotational movement of the stud member to axial movement of the piston.  A sensing device senses axial movement of the piston when the piston compresses the spring, and sends a signal to the robot or end-or-arm tooling device if movement is beyond a predetermined amount.

Patent CA-2141077-A1 (CA)
Inventor: ENOMOTO MASAHIRO
IPC: B65G47/64
Filed: 1995-01-25
Abstract: The present invention provides a conveyor system for divergence and convergence, which is capable of always satisfactorily diverging or converging articles without regard to their size. When the roller axes 19 are orthogonal to the transport path 9, an article 60 to be transported is transported downstream by the rollers 16 without being sorted. When it is desired to sort the article 60, an angle changing device 30 is actuated to individually change the angles of inclination of the rollers 16, such that those rollers which are disposed in the upstream region are given a smaller angle of inclination, the angle of inclination being gradually increased. Diversion of the article can be effected such that it has its direction of orientation gradually changed from a smaller angle to a larger angle while it is gradually moved to one side by a smaller amount to a larger amount. The article 60 can be subjected not to an early (sharp) diverging action but to a sufficient diverging action; thus, it can always be satisfactorily diverged without regard to its size. It can always be satisfactorily converged by the reverse operation.

Patent CA-2167624-A1 (CA)
Inventor: STUDACH CORNEL
IPC: G08B13/16
Filed: 1996-01-19
Abstract: The structure-borne sound detector contains a sensor for picking up structure-borne sound and an electronic evaluation system connected to the latter. The electronic evaluation system has a comb-filter circuit which comprises two comb filters arranged in parallel and of mirror-image construction and whose outputs are fed to a minimum stage. From the minimum stage only the smaller of the output signals of the two comb filters is supplied in each case for further processing.

Filed: 1995-07-06
Abstract: A process and system are disclosed for detecting in particular metallic objects in large-surface search areas (I) and may be advanta-geously used in particular for detecting abandoned hazardous objects. The process, that allows shape, size, orientation, depth and type of material of the search objects to be identified, uses at least one search signal-generating search probe (eddy current probe (15) and/or magnetic field probe) that is moved in relation to the search area (1), preferably in a substantially parallel direction to its surface, along a search path located on a search surface. At least one evaluation unit (20) connected to the search probe so as to receive is signals automatically allocates the search signals to positions of the search probe on the search surface determined by localisation means (4 to 7) and converts the signals into an image of the objects in the search area. The image may for example be a map of the location of the searched objects.

Title: Method and apparatus for improving visibility and selectability of icons
Inventor: SELKER EDWIN JOSEPH
IPC: G09G5/08
Filed: 1996-03-08
Abstract: Enhanced visibility of icons and other types of menu items is provided by increasing size and or skew or both of one or more icons or menu items in a generally inverse relation to proximity of a cursor image address to particular icons or menu items. Increase of size enhances user recognition of an ordinarily small menu item or icon and simultaneously provides the effect of stabilizing cursor position during selection without affecting linearity of response to a graphic input device. Skew and repeated expansion may be used to attract user attention while repeated expansion simplifies icon manipulation by the user in determining a response to a mandatory input demand from an application.
