Patent EP-0047301-A4 (EP)
Title: Apparatus and method for suppressing resonance in an electromanometry system.
Inventor: REYNOLDS GORDON S
IPC: A61B5/02
Filed: 1981-03-10
Abstract: A novel apparatus and method for suppressing unwanted resonance in an electromanometry system. The apparatus includes a compliant air cavity (12) connected through a variable impedance device (14) which is coupled in parallel to the liquid-filled catheter (28) of the electromanometry system. By varying the hydraulic impedance through which the compliant air cavity is coupled to the system, precise impedance matching capability is provided over a wide range of hydraulic impedance values, thereby permitting suppression of unwanted resonance and improved frequency response of recorded waveforms in a wide variety of catheter-transducer systems.

Title: Separable fasteners as well as method and apparatus for adapting separable fasteners for attachment to other objects.
Inventor: PROVOST GEORGE A
IPC: B29L5/00
Filed: 1985-11-20
Abstract: An adapted separable fastener and method of making the same for attachment to other objects such as seat cushions. A separable fastener member (16) of the hook and loop-type is attached, in back-to-back relation, to a substrate (18). The substrate member may either be of an absorbent type, or it may have a plurality of upstanding elements (30) which are ultimately surrounded and encapsulated by foam formed during polymerization. The adapted fastener is thereby attached to a foam member. The elements (30) are positioned in order to allow venting of the gaseous by-product of polymerization. A metallic strip (20) is interposed between the separable fastener member (16) and the substrate member (18) which allows the fastener member (16) to be magnetically held in the mold during the forming of foam objects to facilitate simultaneous forming of the object and attachment of the separable fastener member (16). An apparatus for ultrasonically attaching the separable fastener and the substrate is also disclosed.

Title: High performance digital ignition system for internal combustion engines.
Inventor: BROWN CRAIG R
IPC: F02P7/03
Filed: 1987-04-07
Abstract: A very high performance digital ignition system which includes a precision angular position sensor (4, 5, 6) within the distributor of an internal combustion engine to provide accurate timing information which is applied to gating means (30) for selectively passing bursts of triggering pulses to a driver circuit (34, 38, 40, 46) which provides power amplification to energize the primary circuit of an ignition coil (50). An alternative mode of operation is also disclosed which simulates a conventional make and break ignition system to effect a service mode. In the service mode of operation, a single pulse is issued to the ignition coil upon the occurrence of the first or second pulse of the pulse burst after the angular position sensor has sensed that a cylinder firing operation should be instituted. As a result, ordinary timing and diagnostic instruments may be used during the service mode of operation to very accurately establish the ignition timing during normal, burst mode operation.

Patent EP-0427876-A4 (EP)
Title: Electric spark machining electrode and method of production thereof
IPC: B23H1/04
Filed: 1990-06-05
Abstract: An electrode for engraving electric spark machining which is produced by using a mixture of gypsum hemihydrate powder serving as both a principal material and a binder with a conductive metal powder as a filler, transferring, shaping and hardening the mixture into a desired shape to form electrode material and plating the electrode with the conductive metal. Gypsum hemihydrate powder, gypsum dihydrate powder of less than 1 vol % on the basis of the former and the conductive metal powder are kneaded in a vacuum. Water is added to the kneaded matter, which is again kneaded in a vacuum, poured into a mold to which a predetermined shape is transferred, shaped and hardened by hydration to obtain an electrode material. Then the electrode material is dried and plated with the conductive metal so as to reinforce electrical connection with the metal powder. Since the electrode is made of gypsum as the principal material, even an electrode for electric spark machining to which a precise and complicated shape is transferred can be produced easily, economically, and precisely by the use of a simple mold of, e.g. a silicone rubber, and hence it is particularly suitable for producing dental crowns one by one. Furthermore, gypsum hemihydrate as the principal body of the electrode material and the conductive metal film increase the strength of the electrode by virtue of their synergistic effect. The present invention makes possible machining of a hard material such as titanium for which precise electric spark machining at a desired speed has been difficult by the use of a conventional electrode subjected to impregnation treatment of a conductive solution in which graphite or the like is dispersed in place of plating treatment.

Patent EP-0581900-A4 (EP)
Title: Helical balloon perfusion angioplasty catheter.
Inventor: SHTURMAN LEONID
IPC: A61M25/10
Filed: 1992-04-21
Abstract: A perfusion balloon catheter which permits blood flow through the balloon even when the balloon is inflated. The balloon catheter comprises a thin-walled, collapsible and inflatable tube that has a proximal, generally straight portion, and a distal, helically coiled portion that is generally cylindrically shaped and defines an open lumen therethrough. The successive turns of the coil are secured to one another to maintain the balloon's configuration when inflated. The furled balloon catheter can be inserted to the desired location and then inflated. Because the helically coiled portion defines a relatively large open lumen, blood flow through the balloon can continue even as the inflated balloon remains in place, facilitating extended inflation periods.
Patent EP-0642664-A4 (EP)
Inventor: YAROSH DANIEL B
IPC: G01N33/567
Filed: 1993-05-21
Abstract: L'invention concerne des procédés de recherche de la protéine de réparation de l'ADN, à savoir la O6-méthylguanine-ADN méthyltransférase (MGMT). Lesdits procédés consistent à utiliser des anticorps monoclonaux préparés avec des MGMT présentant une activité transférase, par opposition aux MGMT dénaturés ou aux fragments de MGMT. Les anticorps monoclonaux sont capables de reconnaître la MGMT dans des préparations unicellulaires (essais immunohistochimiques) et dans des extraits cellulaires (essais immunologiques). Pour ce qui concerne la coloration immunohistochimique, l'utilisation d'un affichage fluorescent combiné à la numérisation de l'image de la cellule permet de procéder à la mesure quantitative des niveaux de MGMT dans, par exemple, des échantillons de tumeurs prélevés par biopsie. Ces mesures quantitatives peuvent être utilisées pour déterminer au moyen d'agents alkylants les patients pour lesquels une chimiothérapie peut être nécessaire compte tenu du fait que les cellules tumorables présentant un faible niveau de MGMT sont plus susceptibles d'être tuées par ces agents que celles présentant un niveau de MGMT élevé.
