Abstract: A guidance system (10) for guiding a surgical instrument (12) without visual information to a target (14) in tissue. The system (10) centers the target (14) upon the trajectory of an infinite family of zero-flux curvilinear lines emanating from either a fixed magnet (30) or an ac or dc electromagnet which is mounted on the instrument (12). The approach to the target (14) allows selection of straight and curved trajectories based on the zero-flux lines that intersect the target (14). A self-centering attachment (32) that holds the magnet (30) allows any straight instrument (12) to be guided by the system (10). The zero-flux lines are measured by a magnetometer (34) that is located on a remote location on or in the tissue. The transducers (38, 40, 42) of the magnetometer (34) measure the magnetic field strength that is present if the instrument (12) deviates from the zero-flux line. The guidance information is plotted on a display (50) that allows a user to guide the instrument (12) along the zero-flux line to the target (14).

IPC: G03F1/00
Filed: 2000-06-13
Abstract: A method for producing a digital screen printing blank usable in a screen printing process, directly from digital information in the computer, in an economical fashion. In a preferred embodiment, a screen (28) is provided wit h a photosensitive layer (38), and a digitally determined image from a compute r is printed on the screen by means of an inkjet printer. Preferably, a flat b ed ink-jet imaging system is used so that the screen can be strectched in a fra me and directly placed under the ink-jet head (44). The ink (46) used need not have strong colorant, but functions as a UV mask and thus must contain a UV absorbing pigment. The ink is not absorbed into the photosensitive layer, bu t remains as an undried image (56) on the surface. The ink must remain wet so that it does not spread and therefore gives a sharp image, and so that the U V absorbent material remains concentrated. The solvent of the ink must be chos en so as to assure that it will not affect the screen. The screen is then irradiated with UV, and the areas which have been printed with ink serve to mask the photosensitive layer from the UV light, while those areas having no  ink are exposed so that the photosensitive layer is polymerised by the UV. After the UV irradiation stage, the screen is washed so as to remove the ink  and theunpolymerised photosensitive layer. Any liquid that is suitable for washing out the unpolymerised photosensitive layer will also wash away the ink. This leaves the screen with only the polymerised areas of the photosensitive layer that create the blocked areas through which the ink wil l not pass. Thus, the inventive method provides a digitally imaged screen, directly from a digital image in the computer, which can then be used in any  conventional screen printing process.

Abstract: A plunger (10) for intermittently delivery counterblow air to a gob glass at a formable temperature in a blank mold of a I.S. glass container forming machine that is being operated on the blow and blow process. The plunger comprises a fixed annular member (12) with an enlarged recess (12a) at an inlet end and a valve seat (12d) at an upper end. The plunger also has a sliding valve member (14) within an annulus of the annular member (12), and the valve member (14) has a stem portion (14a) and an enlarged valve seat portion (14b) at a free end thereof. The plunger further has a collar (16) threadably and adjustably secured to the stem portion of the sliding valve member, and the collar, which is slidable within the recess of the annular member, has a plurality of air flow passages (16a) extending therethrough. Pressurized air is intermittently delivered to the recess of the annular member (12) through an inlet line (20), which has an on/off valve (22) therein. When the recess of the annular member (12) is pressurized, pressure therein will act on an underside of the collar to lift the collar and the valve member, jointly, with respect to the annular member, and thereby unseat the valve portion of the valve member from the seat of the annular member. This will permit pressurized air to flow from the recess of the annular member through the air flow passages in the collar, and then outwardly from the plunger through a gap between the valve portion of the valve member and the valve seat of the annular member. Upon the depressurization of the recess of the annular member, the valve member and the collar will return, by gravity, to a position where the valve portion of the valve member is seated against the valve seat of the annular member.

Abstract: Disclosed is a method for detecting 5-methylcytosine in genomic DNA samples.  First, genomic DNA from a DNA sample is chemically reacted with a reagent, 5-methylcytosine and cytosine reacting differently. The pre-treated DNA is then ampified with primers from a different sequence using a polymerase. In the following step, the amplified genomic DNA is hybridised to an oligonucleotide array and PCR products are obtained which must be provided with an identifying mark. Alternatively, the PCR products can be extended in a Primer Extension Reaction, the extension products also being provided with an identifying mark.  The last step involves examining the extended oligonucleotides for the presence of the identifying mark.
