Title: Process of preparing for alpha-l-aspatyl-l-phehylallanine alkylaster
Inventor: AN GI-HWAN
IPC: C07K7/00
Filed: 1982-12-31
Granted: 1985-02-15
Abstract: The title compd. I (α-L-aspatyl-L-phenylalanine alkylester), useful as a low-calorie synthetic sweetening agent, were prepared. The β-carboxyl hydrogen atom of asparagine was substituted by a monovalent ion of alkali metal, and the α-amino group was protected with a schiff-base and condensated with phenylalanine methylester in the presence of N-succinymidylphenylphosphate. This was treated with acid to remove the protected group to give high purified α-peptides. The title compds were prepd. using four steps.

Title: Heated railroad tank car
Inventor: LOEVINGER RICHARD P
IPC: B65D88/74
Filed: 1983-06-03
Granted: 1988-10-08
Abstract: The heated tank has a heat exchanger spaced from the bottom of the car to define a dead space to insulate the heat exchanger from the bottom.  The heat exchanger extends longitudinally and transversely across the entire bottom of the car to provide a large heating transfer surface to the lading supported by the exchanger.  A portion of the exchanger encompasses a discharge valve of the tank car to provide heat transfer to the valve during unloading.  The heat exchanger slopes toward the discharge valve to facilitate total removal of the lading.  An inlet and an outlet associated with the heat exchanger are disposed adjacent the discharge valve for additional transfer of heat to the discharge valve.

Title: Devices using nuclear magnetic resonance
Inventor: SUZUKI MASAHARU
IPC: G01R33/48
Filed: 1983-09-30
Granted: 1987-04-06
Abstract: The appts. has a steady magnetic field applied to the longitudinal axis of the patient by a magnet. Coils apply a first gradiant field in a field direction parallel to that of the steady field, but with a field strength which changes linearly oppositely to the steady field along the longitudinal axis. RF pulses are applied by a probe head coil to excite the nucleus and detect NMR signals from the patient. A second coil applies a seocnd gradient field having a different strength from that of the first gradient field. The NMR signals are processed using two-dimensional fourier transformation.

Title: Method and apparatus for drawing low loss fiber optic coupler
Inventor: KECK DONALD B
IPC: G02B6/02
Filed: 1986-08-14
Granted: 1992-03-31
Abstract: A low loss fiber optic coupler is fabricated by forming a coupler preform (10) having a plurality of spaced glass cores (12,13) extending longitudinally through a matrix of glass having a refractive index lower than that of the cores. The preform is heated and stretched to form a glass rod (20) which is then severed into a plurality of units (21). Heat is applied to the central region (23) of each unit while the ends of the unit are pulled apart to elongate the taper inwardly the heated central region. The unit is then provided with a plurality of optical fibers (69, 70, 75, 76°, 82, 83; 89), one of which extends from each of the cores at the endfaces of the unit. A preferred method of providing the optical fibers involves forming the coupler preform of a matrix glass (46) that is easily dissolves in a solvent. Each of the fiber cores within the matrix is surrounded by a layer of cladding glass (54) that is relatively resistant to disolving by the solvent.

Title: Protective apparatus for neon-lamp
Inventor: CHONG CHUNG-SI
IPC: H05B41/36
Filed: 1988-08-12
Granted: 1991-03-04
Abstract: The proposed circuit detects the primary  voltage  varitation instead of the secondary voltage variation as in the  conventional scheme, while preventing malfunction upon either starting  in-rush current flow or no current flow. Such an operation enables not  to destroy (deteriorate) insulation or not  to  injured  in  electric shock on working. The primary voltage is  sensed  by  the  voltage detector (VD) across a resistance R, connected in series with  the primary winding (L1). If VD detects a setting value  over,  output of two non-inverting op Amp (A1),(A2) activate photocoupler (PC1), and then Tr(Q3) and LED (LD) switches on Triac(TR1) which cuts off the power supply.

Abstract: The method for  minimizing  the  locking  time  comprises:  a filter means (6) connected to the intermediate frequency means (5) and passing only the signal of specific frequency (HMCT); a  means (7) connected to the band pass filter means of specific  frequency (6) and  rectifying  the  negative  part  of  detected  signal;  a detecting and  comparing  means  (8)  connected  to  the  negative rectifying  means  (7)  and  the  main  processing  unit  (9)  and outputting the detected specific frequency to the  MPU  (9).  This method is useful for communication products using multi-channel.
