Title: Process for the enantioselection synthesis of alkylated oxindoles used as intermediates in the preparation of physostigmine
Inventor: LEE THOMAS BING KIN DR
IPC: C07B61/00
Filed: 1990-12-28
Abstract: A process for the stereoselective synthesis of [R]- and [S]-2,3-dihydro-1,3-dimethyl-2-oxo-1H-indole-3-acetonitriles comprises reacting racemic and 5-alkoxy-substituted (+/-)-1,3-dimethyloxindoles with a halogenated acetonitrile in the presence of a substituted N-benzyl cinchoninium, quinidinium, cinchonidinium, or quininium catalyst. The resulting alkylated oxindoles can be converted to primary amines by catalytic reduction in the presence of hydrogen gas. One of the primary amines, such as enantiomers of 3-(2-aminoethyl)-1,3-dihydro-1,3-dimethyl-5-methoxy-2H-indol-2-one, can be enriched by contact with a chiral tartaric acid in an amount sufficient to preferentially precipitate a salt of the chiral acid and one of the enantiomers. The product can be used in the synthesis of stereospecific forms of physostigmine and related compounds having pharmaceutical activity.

Title: Reagent containment and delivery tray
IPC: B01L3/00
Filed: 1991-07-20
Abstract: A high-precision liquid reagent delivery system is provided for convenient and efficient gravity flow delivery of substantially the entire volume of reagent contained within a sealed formed tray. The delivery system comprises a formed tray (10) defining a curved cavity (12) for holding a predetermined amount of liquid, and a substantially planar ledge surface (14) defined around the cavity opening. The surfaces of the cavity are non-porous, uniform and smoothly converging to a point (20) of liquid discharge at an intersection of the cavity and the ledge surface (22). The ledge surface further defines an apex extending longitudinally from the point of liquid discharge and defines a guide path for the delivery of liquid contained within the tray (10). The system also includes a flexible cover (40) removably affixed to the ledge surface of the tray for forming a sealed chamber between the cavity (12) and the affixed cover (40) for containment of liquid. The cover (40) extends beyond the apex (22) of the ledge surface (14) to define a tab portion (42) which can be grasped and pulled from the ledge surface (14) to remove the cover (40). Removal of the flexible cover (40) in such a manner with the tray (10) positioned in a upstanding manner with the point of liquid discharge (20) directed downward provides gravity flow delivery of all liquid contained within the tray (10) with a low coefficient of variation. <IMAGE>

Patent EP-0529193-A3 (EP)
IPC: H04N1/401
Filed: 1992-03-25
Abstract: An image-reading device, in which the 1-bit signals 
a CCD line sensor has generated from the light applied 
from an illumination lamp and reflected from an original 
(G) are shading-corrected, thereby forming image data. 
Before scanning the original, a black reference signal 
(V BK ), a white reference signal (V WT -V BK ) at a level 
higher than that of the black reference level, and three 
intermediate reference signals (V M1 , V M2 , V M3 ) are 
generated and stored into memories (44,45, 461, 462, 463). 
During the scanning of the original, a selector (49) 
selects two of the reference signals in accordance with 
the level of each signal output by the CCD line sensor, 
and the difference between the signal output by the 
sensor and the black reference signal (V BK ) is shading-corrected, 
by using the two reference signals selected 
by the selector (49). The signal output by the CCD line 
sensor can therefore made linearly proportional to the 
intensity of the input light, even if the CCD line 
sensor has no linear input-output characteristic or even 
if the photoelectric elements of the sensor have different 
input-output characteristics.

IPC: H04N5/225
Filed: 1992-08-26
Abstract: A camera apparatus in which a video camera and a 
photographic camera are integrally combined or which has a 
self-timer function, and an aspect conversion circuit for 
converting the orientation of an image are provided. A 
normal mode and a self-timer mode are provided, and in 
either mode, a shutter pulse synchronized with a vertical 
synchronizing signal is obtained from an output signal of a 
frequency divider, while in the self-timer mode, a timer is 
driven by the output signal of the frequency divider, 
whereby the frequency divider is used in both modes. 
Alternatively, a still mode and a video mode is provided, 
and in the still mode, a shutter pulse and a record pulse 
are output in response to an operation of a shutter switch, 
while in the video mode, the record pulse is output in 
response to an operation of a record switch and the shutter 
pulse is output in response to an operation of the shutter 
switch. Furthermore, a field memory or a frame memory is 
arranged in the aspect conversion circuit, and a write 
direction with respect to the memory is made different from 
a read direction, to thereby obtain an aspect-converted 
video signal.

Title: Semiconductor integrated logic circuit with a test mode
Inventor: OGAWA TADAHIKO
IPC: G01R31/3185
Filed: 1993-06-14
Abstract: In a semiconductor integrated logic circuit, latch circuits are provided to hold the input signal supplied to a random logic circuit just before an operation mode is switched from a normal operation mode to a test operation mode. During the test operation mode, the latched signals are continued to be supplied to random logic circuit so that the operation condition of a internal circuit of the random logic circuit is maintained as it is. Therefore, when the circuit is returned from the test operation mode to the normal operation mode, the circuit operation of the internal circuit of the random logic circuit continuing from the circuit operation in the previous normal operation condition can be obtained. <IMAGE>

Patent EP-0690243-A3 (EP)
IPC: F16F1/14
Filed: 1995-06-19
Abstract: An adjustable elastomer torsion device includes a base 
member aligned in partially nested relation with a resilient 
elastomer (e.g. rubber or urethane resin) torsion member; 
parts of the base member and the torsion member overlap each 
other and an extension portion of the torsion member 
projects beyond the base member. The base member and the 
torsion member are interlocked, where they overlap each 
other, to prevent relative twisting between them, but the 
interlock does not interfere with twisting of the torsion 
member extension. An adjustment mechanism provides for 
adjustment of the positions of the base and torsion members 
relative to each other to vary the length of the extension 
portion of the torsion member over a given displacement 
length and thereby adjust the elastomeric, resilient 
torsional restoration force (torsional resistance) of the 
device within a predetermined force range. In some 
versions, the base member is a resilient elastomer, so that 
some twisting occurs in the base member; in others the base 
member does not twist preceptibly.

Abstract: A novel cell line chronically infected with HIV-2NIHZ virus secretes the precursor of the viral envelope proteins in extracellular medium. The cells grow well in serum-free medium which enables the concentration of the conditioned medium of the cells to be greatly increased (>100 fold). Such a concentration step is otherwise impossible to achieve if the cells are grown under conventional conditions using 10% fetal calf serum. A specific affinity procedure is provided to purify the gp160 protein from the concentrated conditioned medium of cultures of 100 liter batches using a mouse monoclonal antibody to the HIV-2 gp41 protein, which is a part of the gp160 protein. This purified HIV-2 gp160 reacts with high specificity and sensitivity with the anti viral antibodies of HIV-2 infected humans by several criteria such as i) ELISA, ii) western blot analysis, and iii) radioimmuno-precipitation of metabolically labeled gp160 from the same cell line. The purified HIV-2 gp160 from this cell line is therefore a diagnostic tool for the detection of HIV-2 infection in humans. In view of the predicted oligomeric property of gp160 and its close conformational similarity to the virion envelope, the purified gp160 can also be useful for the development of vaccine strategies against HIV-2 in humans.
