Title: Cell line and assay to determine biological activity of retinoids
Inventor: HOULE BENOIT
IPC: G01N33/50
Filed: 1993-01-28
Abstract: ABSTRACT OF THE INVENTION         The present invention relates to an assay and cell lines for determining the biological effects of retinoids.  The cell line is derived from a human lung tumour  line which  is  tumorigenic  in  nude  mice  and expressed undetectable  levels  of  the  .beta.  receptor  of retinoic acid by introducing in a stable fashion the DNA coding for this receptor.  The novel line is non-tumorigenic and grows in culture at a rate which is reduced in the presence of 10-7 M retinoic acid.  This line is useful in determining the biological effects of novel retinoids which act in particular by activating RAR.beta..

Title: Hydrocyclone conduits
Inventor: PAPETTI RICHARD R
IPC: B04C11/00
Filed: 1993-02-12
Abstract: HYDROCYCLONE CONDUITS                ABSTRACT OF THE DISCLOSURE       Hydrocyclone separators of the type used to separate contaminants from pulp suspensions in paper mills are connected to feed, accept, and reject conduits using a conduit apparatus in which both feed and accept portions can be made from smooth material.  The feed and accept portions include surfaces through which apertures are provided for making connections to the feed and accept nozzles of the hydrocyclones.  The smooth material eliminates the tendency of pulp to build up on the conduit walls and in the nozzles, thereby avoiding the problems that can occur when such build ups break loose.          The nozzles of the hydrocyclones are preferably attached by placing a resilient sealing member around the circumference of the nozzle, and inserting the nozzle into an aperture formed in the wall of the conduit until the sealing member engages the inside wall of the aperture.  The wall of the conduit can include a generally flat portion made from a metal plate material so that the sealing member seals only against the narrow, generally-cylindrical inside surface of the aperture.          The wall can also be molded of a plastic material and can have an aperture dimensioned so that a length between the exterior and interior walls changes around the aperture.          A manifold is also provided which is useable between the main feed and main accept conduits so that it can either be parallel therewith or transverse thereto.     22454.B11

Inventor: UOMORI KENYA
IPC: A61B3/113
Filed: 1993-02-25
Abstract: In an apparatus for examining gaze shift in depth direction, light emitting diodes B and E, or D and C are lit at a plurality of positions with different distance in depth direction from the subject, and eye movement of the subject at that time is detected by an eye movement detecting portion (2).  The signal of detection is processed in a signal processing circuit (5) and is applied to a calculating portion (1).  The calculating portion (1) determines whether or not there is a disorder in gaze shift in depth direction of the subject by using any or all of latency in eye movement, time constant, amplitude, change in convergence angle, number of occurrence of saccade, and asymmetry of left and right eye movements, in response to the detected output of the eye movement.

Title: Intaglio printing machine
Inventor: GERMANN ALBRECHT J
IPC: B41F11/02
Filed: 1993-03-08
Abstract: The intaglio printing machine has three machine stands (I, II, III). Essentially, the impression cylinder (1) and the plate cylinder (2) are mounted in the first stand (I), the stencil rollers (10) and the inking unit (11) are mounted in the second stand (II), and the color-collect cylinder (8) is mounted in the third stand (III).      The third stand (III) is adjustable in such a way that it can be removed from the space between the first and second stands and brought into an inoperative position, so that it is possible to bring the second stand (II) up against the first stand (I) to form an intaglio printing machine with direct inking. This results in a convertible intaglio printing machine by means of which a collect intaglio print can be made in a first operating position, in which all three stands assume their working position, and a direct intaglio print can be made in a second operating position, with the use of only the first and second stands.

Title: Composite densification with benzoxazines
Inventor: ISHIDA HATSUO
IPC: C07D265/16
Filed: 1992-03-10
Abstract: A method for forming carbon-carbon composites consists of impregnating structures with carbon-forming precursor compounds comprising multi-functional benzoxazine compounds. The impregnated structures are pyrolyzed to form carbonaceous char which serves to fill the interstices in the structure, thus densifying the composites. The process of impregnation and pyrolysis is repeated as many times as required to obtain the composite density desired.  Unusually high char yields are produced by multi-functional benzoxazine compounds in which benzoxazine structures are joined to each other through a bridge characterized by having conjugated unsaturation associated therewith. A number of preferred compounds providing unexpectedly high yields of char are disclosed, enabling the desired densification to be achieved with a minimum number of impregnation and pyrolysis cycles, thereby reducing the costs of forming the composites.
