Abstract: Abrégé Magnétomètre à résonance magnétique nucléaire Deux demi-bobines (181,182) prélèvent un signal de précession des spins nucléaires de deux échantillons (200). Un condensateur d'une batterie (22) de condensateurs forme avec les deux demi-bobines un circuit résonant. Le signal aux bornes du condensateur est amplifié dans un amplificateur différentiel (121), déphasé dans un déphaseur (28) introduisant un déphasage constant de 90.degree., et réinjecté dans les demi-bobines par l'intermédiaire d'un potentiomètre (321). La fréquence des oscillations est mesurée par un fréquencemètre (161). Un circuit (26) commande la connexion des condensateurs de la batterie (22) en réponse à la valeur de la fréquence mesurée, pour maintenir inférieurs à un seuil les déphasages parasites entre signaux prélevés et signaux réinjectés.

Granted: 1992-03-31
Abstract: Attorney's Docket No. 7964 INVENTOR:  MARTIN IMHOF          INVENTION: ENDOPROSTHESIS FOR A HIP-JOINT SOCKET     ABSTRACT OF THE DISCLOSURE     A shell sleeve serves for the reception of a bearing socket.  The shell sleeve possesses the shape of a body of revolution or rotation which tapers or narrows towards a pole region.  This body of revolution carries at its outer surface a self-tapping thread.  To facilitate threading-in of the shell sleeve into the bone substance or material and to preclude, during such threading-in operation, the application of forces which would cause any pressure and splintering action upon the bone substance or material, the thread comprises a flat thread.  This flat thread has flanks dispositioned at essentially right angles to the lengthwise axis of the body of revolution and the spacing from thread flight to thread flight is constant.  The portions of the thread flights which follow a related cutter or cutting surface thereof are undercut or machined back.     WWX:sm:sncd9

Abstract: NEGATIVE AND ZERO SEQUENCE DIRECTIONAL OVERCURRENT       UNIT FOR AC POWER TRANSMISSION LINE PROTECTION                 ABSTRACT OF THE DISCLOSURE         A protective relay for detecting faults within a predetermined protected zone of a three phase alternating current electrical power distribution system, of the type which utilizes at least one restraint signal in conjunction with at least one operate signal to generate a net operate signal, generates an operate quantity which is related to a zero sequence component of current flowing in the power distribution system and a second operate quantity which is related to a negative sequence component of the current flowing in the power distribution system.  The operate quantities are summed to form an operate signal.  An adaptive restraint, which is proportional to a negative sequence component of a phase voltage of the power distribution system, is generated and utilized to provide increased sensitivity to higher resistance ground faults.  A portion of a positive sequence component of the current flowing in the power distribution signal is utilized as a restraint signal to prevent the unit from operating on negative sequence currents present during normal load conditions.  Adaptive restraint enables the directional overcurrent unit to operate correctly should a second fault occur on the transmission line during the period that one pole is open.

Title: Sheet diverting and delivery system
Inventor: LITTLETON FRANCIS J
IPC: B65H29/58
Filed: 1989-02-01
Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for diverting and delivering sheets in which the sheets are positively controlled throughout the entire operation.  Initially, a continuous web of paper passes between opposing cylinders comprising a rotary cutter.  The lead edge of the web is then engaged by a pair of opposed nip rollers.  Once held by these nip rollers, the rotary knife cuts a separate sheet from the front of the continuous web.  The separate sheet then passes between and is accelerated by the nip rollers whereupon a dual set of diverting cams, in combination with a pair of conveyors, directs the sheet to one of two delivery systems.  The next subsequent sheet is directed to the other delivery system so that each successive sheet is alternately diverted between the two delivery systems. Upon exiting either delivery system, the sheet is subjected to a snubbing means which decelerates the sheet and further allows the next subsequent sheet to overlap the previous sheet before being similarly decelerated. The shingled sheets are then transmitted by conveyor to a subsequent processing operation.

Abstract: APPARATUS AND SYSTEM FOR APPLICATION AND ADJUSTABLE REPROFILING OF SYNTHETIC LENTICULES FOR VISION CORRECTION                          ABSTRACT      An apparatus and system for applying a synthetic lenticule to the cornea of a human eye is disclosed, the process also contemplating selective reprofiling of the lenticule while it is in place over the cornea.  The process involves ablating a shallow peripheral groove in the cornea to receive the peripheral edge of the lenticule which is then secured therein with an adhesive, thus leaving the visual axis of the eye undisturbed.  The lenticule is placed over the cornea with a unique micromanipulation apparatus and normally under vacuum conditions.  A laser delivery system is used to reprofile the lenticule if necessary for refining the refractive power of the lenticule.

Title: Image display apparatus and method of fabrication thereof
Inventor: WATANABE MASANORI
IPC: H01J1/304
Filed: 1989-08-08
Granted: 1993-11-02
Abstract: ABSTRACT OF THE DISCLOSURE         An image display apparatus comprising an insulating substrate having electron sources controlled by X-Y matrix electrodes and a face plate coated with a phosphor material in opposed relationship with the substrate is disclosed.  An electron source at each intersection of the X-Y matrix control electrondes is made up of a plurality of cold cathodes connected to an X-control electrode and a plurality of gate electrodes connected to a Y-control electrode opposed to the cold cathodes in the same plane, and the electron source is formed on the substrate surface on other than the X- and Y-control electrodes.  A voltage applied between the cold cathodes and gate electrodes arranged in opposed relations on the same surface causes a high electric field of about 107 V/cm at the forward end of the cold cathodes leading to an electron emission.  A part of electrons thus emitted enters the anodes directly.          Another part of electrons flow into the opposed gate electrodes to generate secondary electrons in the surface of the gate electrodes.  The secondary electrons thus generated are accelerated by the positive voltage (anode voltage) applied to the phosphor surface of the opposed face plate and bombarded on the phosphor material, which is thus illuminated.
