Title: Injection molded preform, method of treating same and container formed therefrom
Inventor: COLLETTE WAYNE N
IPC: B29C49/06
Filed: 1990-01-19
Abstract: A polyester preform which is injection molded preferably of PET and wherein the preform is provided with a molded neck finish or neck portion including threads which are molded to a high tolerance and wherein the neck finish may receive a closure cap of the type having a tamper indicating band which engages over a retaining bead also molded to a high tolerance as part of the neck finish. In order to maintain the container which is blow molded from the preform in axial alignment with the neck finish and thus eliminate the perpendicularity problem, a ring of the preform immediately below the flange which functions as the capping ring, is heated to a high temperature and crystallized. In a like manner, the end sealing surface is also heated to a high temperature and crystallized.      The remainder of the neck finish remains in its amorphous state without disturbing the configuration of either the threads or the retaining bead. This combination of crystallized portions with the remainder of the neck finish remaining amorphous assures a high quality connection between a closure cap, whether the closure cap is formed of plastic or metal, while providing the end sealing surface with a hard tough finish resisting deformation and at the same time reducing the closure cap removal torque.

Patent CA-2016755-A1 (CA)
IPC: G01R31/3185
Filed: 1990-05-14
Abstract: A structure and method for producing mask-configured integrated circuits which are pin compatible substitutes for user-configured logic arrays is disclosed.  Mask-defined routing lines having resistive/capacitive characteristics simulating those of user-configurable routing paths in the user-configurable logic array are used in the mask-defined substitutes to replace the user-configurable routing paths.  Scan testing networks are formed in the metal-configured substitutes to test the operability of logical function blocks formed on such chips.  The scan testing networks comprise a plurality of test blocks each including three field effect pass transistors formed of four adjacent diffusion regions.  Proper connection of the gates of these pass transistors to control lines controlling the transistors is tested by trans-mitting alternating high/low signals through serial conduction paths including the gate electrodes of these transistors.

Title: Method and apparatus for producing layers of hard carbon modification
Inventor: BUCK VOLKER
IPC: H01J37/32
Filed: 1990-11-26
Abstract: ABSTRACT OF THE DISCLOSURE    A method of producing layers of hard carbon modifi-cations on a substrate includes disposing the substrate in a vacuum chamber in which an anode electrode and a cathode electrode are disposed and spaced from one another.  The anode electrode is made of a carbon containing agent and serves as a carbon source when a direct current is formed between the spaced electrodes.  The two electrodes are energized forming a direct current arc in the vacuum between the spaced electrodes; and hydrogen is introduced directly into the region of the arc by flowing hydrogen through at least one of the two electrodes while simultaneously maintaining the arc between the electrodes to feed the arc with carbon from the anode thereby coating a surface of the substrate with a hard carbon layer.

Abstract: ABSTRACT           WHEN SUBSTITUTING A FREEZING AGGREGATOR OF 4,000. kilo calories AND ITS electromotor of 4 Kilo Watts WITH SUCH OF 1,100. kilo calories and an electromotor of 1 Kilo Watts WE ARRIVE TO A REDUCTION IN THE USE OF ELECTRIC ENERGY IN A RATIO OF 4 TO 1.         I HAVE DEVELOPED THIS ON AN EXPERIMENTAL BASIS AT THE "HIGHER MEDICAL INSTITUTE" OF VARNA (BULGARIA) AND 3 PROFESSORS OF THE "HIGHER MECHANICAL ELECTROTECHNICAL INSTITUTE" OF SOFIA HAVE GIVEN THEIR CONSENT IN WRITING FOR THE PRACTICAL APPLICATION OF THE SAME.         I CONTINUED TO EXPERIMENT WITH THE SAME PRINCIPAL AND SUBSEQUENTLY WAS ABLE TO PRODUCE EVEN FURTHER REDUCTIONS IN A RATIO OF ABOUT EIGHT, NINE OR TEN TO ONE.         IN ALL MY SCIENTIFIC RESEARCH I BECAME CONVINCED THAT THERE IS NO NEED FOR LARGE AGGREGATORS WITH LARGE ELECTROMOTORS OF LARGE AND IMPOSING TECHNOLOGY AND STRUCTURE.  IF WE SUBSTITUTE ONE SYSTEM WITH ANOTHER, AS I SUGGEST WE DO, THEN THE EFFECT IS MUCH IMPROVED. HERE IS HOW WE GO ABOUT THIS: 1.   THE INSTALLATION OF THERMO REGULATING VALVE (THROTING DEVICE) IS TO BE LEFT OUTSIDE THE ELECTRIC CAMERA, FOR EXTREMELY LOW TEMPERATURES, AND FOR OTHERS IMMEDIATELY BY THE ENTRANCE OF THE TUBES OF THE COOLING CAMERA NEXT TO THE COOLING MECHANISM. 2.   THE INSTALLATION OF COOLING AGGREGATORS TO BE IMMEDIATELY NEXT      TO THE COOLING CAMERA. 3.   THE INCREASE OF THE COOLING SURFACE IS ARRIVED AT BY      INCREASING THE LENGTH OF THE COOLING PIPES NOT WIDER THAN 12 mm, ACCORDING TO THE COOLING CAPACITY OF THE UNIT. 4.   THE PRECISE MONITORING OF THE THERMO REGULATING VALVE IN      CONJUNCTION WITH SMALLER AGGREGATORS LEADS IN EFFECT TO   1.  AND SUBSEQUENTLY THE USE OF FERONE IN THE SAME RATIO.         I AM SUBMITTING SCHEMES AND DRAWINGS OF EXISTING SMALL AGGREGATORS WHICH CAN BE USED TO REPLACE LARGE ONES.    WE CAN FIND BEST SOME OF THE APPLICATIONS OF THIS ENERGY REDUCTION SYSTEM IN:         -   ALL WALKS OF FREEZING AND COOLING UNITS IN THE FOOD INDUSTRY -   ALL FREEZING UNITS IN THE MEDICAL SCIENTIFIC RESEARCH     LABORATORIES -   ALL COOLING UNITS ON BOATS AND SUBMARINES -   ALL RESIDENTIAL AND COMMERCIAL AIRCONDITIONING SYSTEMS         THE REDUCTION OF THE USE OF FERONE BY THE SAME RATIO OF ONE TO TEN WILL FOLLOW IN A RAPID REDUCTION IN THE EROSION OF THE OZONE LAYER.

Abstract: RF ABLATION CATHETER                     ABSTRACT OF THE DISCLOSURE      An intravasaular catheter especially designed to surgically remove atheromas or other forms of stenotic or thrombotic lesions from the interior walls of a blood vessel using an RF discharge between two bipolar electrodes is described.  Affixed to the distal end of an elongated, flexible, plastic, tubular member is a bipolar electrode structure comprising a cylindrical insulator having a first conductive metal ring electrode surrounding the periphery of that insulator.  Projecting from the distal end of the cylindrical insulator is a second, frusto-conical shaped member whose major base  is  slightly  less  in diameter than the diameter of the cylindrical insulator.  An insulative material covers all but the distal side edge of the first ring electrode and an annular zone of the second electrode located immediately adjacent to the exposed distal side edge of the first electrode.  Wires running through the lumen of the tubular member couple the first and second electrodes to an RF generator coupled to the catheter's proximal end.  When appropriately energized, an intense current flow path is created between the exposed electrode surfaces for cutting through the blood vessel obstruction.   The cone shaped member is rotatable about  an  axis  which  is  eccentric  to  the  centerline  of  the cylindrical insulator and by manually manipulating a torquing wire or tube at its proximal end, the electrode gap can be varied to control the location where cutting occurs.  A motor device may also be used to continuously rotate the torquing wire.

Abstract: ABSTRACT OF THE DISCLOSURE      An eddy current imaging system (15) includes an eddy current sensing coil (17) positioned proximate a workpiece  for  scanning the workpiece to produce  a signal  (21,  22)  indicative of the integrity of the workpiece for regions in an x, y array of data.  Such a signal (21, 22) may be a complex impedance signal representative of the amplitude and/or the phase of the  signal.    Two  data  processing  techniques  are disclosed for enhancing the display of a flaw in the workpiece.    The  first  includes  the  step  (30)  of calculating  a  spatial  derivative  of  the  amplitude and/or phase indicative signal from the coil (17) and providing  an  image  of  the  spatial  derivative  to produce a  C scan of the  spatial  derivative.   The second includes the steps (35, 36) of determining the regions of maximum ascent and/or descent of the signal for regions in the scan and calculating an impedance plane trajectory from the data array of path points for  displaying   a   reconstructed   optimum   signal independent of path pattern.
