Title: Structural examination using holographic interferometry
Inventor: CLARK ROBERT KEITH
IPC: G01B11/16
Filed: 1991-12-20
Abstract: In-situ, nondestructive examination to test the efficacy of a rivetted, bolted or bonded join of metal sheets (10, 11), or to test whether a composite material is faulted, or to test whether a multi-layer patch is bonded properly, involves the creation of an interferometric hologram. A photographic film or plate (20) is mounted closely above, and isolated vibrationally from a region (21) of a structure containing the join, composite material or patch.  The film or plate is illuminated by the expanded beam (26) from a laser (24) firstly when the structure is in a first state of stress, and secondly when the structure is in a second state of stress (the change in stress being sufficient to deform the region over which the film or plate is mounted). At each illumination, a diffraction pattern is produced in the emulsion of the plate or film by interference between the illuminating beam and that part of it which is reflected from the region. The two diffraction patterns combine to produce a fringe pattern in the emulsion. That fringe pattern, when compared with the fringe pattern produced by a good join or a non-faulted composite body or patch, provides information about the region under investigation. The technique is especially useful for testing the joins in the skin of an aircraft fuselage, or potentially damaged composite structures.

Abstract: The present invention relates to novel class of immunosuppressive compounds having an affinity for the FK-506 binding protein (FKBP). Once bound to this protein, the immunosuppressive compounds inhibit the prolyl peptidyl cis-trans isomerase (rotamase) activity of the FKBP and inhibit T cell activation. As such, the compounds of this invention can be used as immunosuppressive drugs to prevent or significantly reduce graft rejection in bone marrow and organ transplantations and for use in the treatment of a wide variety of autoimmune diseases in humans and other mammals.      These compounds are represented by formula (I), in which the different substituents are defined in the description.

Patent CA-2122248-A1 (CA)
Inventor: SMITH KENNETH W
IPC: F02P3/08
Filed: 1993-09-08
Abstract: An ignition system is provided that marries a free-running discharge circuit with a fast-charging, high voltage converter without resulting in an excessive rate of discharge.  To this end, the free-running discharge circuit employs a passive switch embodied either as a spark-gap device or a passive network of semiconductor elements.  A feedback circuit detects discharge events at the discharge circuit and, in response thereto, selectively enables and disables the fast-charging converter.  A spark rate clock is integrated into the feedback circuit for the purpose of setting the average discharge rate to a predetermined value.

Title: Novel human cdc25 genes, encoded products and uses therefor
Inventor: BEACH DAVID H
IPC: C12Q1/68
Filed: 1992-11-17
Abstract: Two previously undescribed human cdc25 genes, designated cdc25 A and cdc25 B, which have been shown to have an en-dogenous tyrosine phosphatase activity that can be specifically activated by B-type cyclin, in the complete absence of cdc2 are de-scribed. As a result of this work, new approaches to regulating the cell cycle in eukaryotic cells and, particularly, to regulating the activity of tyrosine specific phosphatases which play a key role in the cell cycle are available. Applicant's invention relates to methods of regulating the cell cycle and, specifically, to regulating activation of cdc2-kinase, through alteration of the activity and/or levels of tyrosine phosphatases or through alteration of the interaction of components of MPF. The present invention also relates to agents or compositions useful in the method of regulating (inhibiting or enhancing) the cell cycle. Such agents or com-positions can be inhibitors (such as low molecular weight peptides or compounds, either organic or inorganic) of the catalytic ac-tivity of tyrosine specific PTPases (particularly cdc25), blocking agents which interfere with interaction or binding of the tyrosine specific PTPase with cyclin or the cyclin/cdc2 complex, or agents which interfere directly with the catalytic activity of the PTPases. The invention also pertains to an assay for identifying agents which alter stimulation of kinase activity of pre-MPF and thus alter activation of MPF and entry into mitosis. Such agents are also the subject of this invention.

The process offers very high recovery yields both for precious metals, in particular rhodium, and for cerium.

Inventor: CHAPMAN JOSEPH Q
IPC: H03M1/00
Filed: 1994-09-27
Abstract: CALL ESTABLISHMENT FOR SIMULTANEOUS ANALOG AND             DIGITAL COMMUNICATIONS Abstract A modem, capable of simultaneously coupling voice and data signals, connects local digital terminal equipment (DTE) and a local telephone to a communications link. To prevent the local DTE from responding to a communications containing only voice signals, the local DTE is notified of an incoming communication only after detection of calling tone signals on the communications link. Such signals indicate a remote DTE desires to establish a data communications path with the local DTE. This operation advantageously prevents the modem from transmitting an annoying answer tone to a calling party.
