Abstract: Pyrrole derivs. I [R1 = H, alkyl, phenyl 2-pyridyl; R2 = H, alkyl, R3,R4 = alkyl, cycloalkyl; NR3R4 = heterocycle  were prepd. Thus (Me2CH)2NCH2CH2C(CO2Et)2NHAc were hydrolyzed and decarboxylated to (Me2CH)2NCH2CH2CH(NH2)CO2H, which was amidated via an Me ester and treated with (MeCOCH2)2 to give I derivs. (II). At 50 mg/kg orally in dogs, II gave 90% inhibition of ventricular arrhythmia. Also at 50 mg/kg day orally for 5 days in baboons, II inhibited blood platelet aggregation.

Title: Optical recorder provided digital information signal
Inventor: IMMINK KORNELIS A S
IPC: G11B7/00
Filed: 1988-11-03
Granted: 1989-06-24
Abstract: The method of recording a binary information signal on a data storage medium uses an active layer responding to radiation to permit recording of data by control of the incident radiation by generating radiation pulses of fixed intensity and duration at controlled intervals.  The binary data stream is converted to a binary modulted signal using Miller modulation which permits only 2,3 or 4 bit cells per binary interval.  To increase the data storage density the recording radiation is modulated to produce an impulse between the bit cells of the Miller encoded signal, thus generating one impulse for 2 bits, 2 for 3 bits, and 3 for 4 bits.

Abstract: The apparatus prevents overcurrent flow  by  using  a  proper relay which only cuts off the  load  loops  having  some  troubles instead of a whole system. When the liquid level in a tank reaches an  upper limit,  detecting  level  sensors  (E1,E3)  are   short circuited and switching transistors (Q1,Q3)  are  turned  on.  And relays (K1,K2) are activated to make a water supply indicator (L2) turn on, and supply a  load  power  by  activating  a  relay  (K4) through a relay (K3). On the other hand, when the level comes down to the  low  limit  level,  a  sensor  (E2)  turns  the  switching transistors (Q1,Q2) off and load  power  supply  is  cut  off.  An overcurrent status outputs a detecting DC current which  activates the relays (K3,K4) to cut off a load power supply.

Title: Method of indentifying telephone numbers
Inventor: LEE UI-JAE
IPC: H04M1/65
Filed: 1991-07-26
Granted: 1994-06-30
Abstract: The method for confirming a received telephone number by speech synthesis in a remote place comprises the steps of: sending an announcement voice message in response to a ring signal input and checking whether a secret number is received; if the secret number is not received, storing a received telephone number in an internal memory; and if the secret number is received, sending, by speech synthesis, voice data corresponding to a dial digit stored in the internal memory, thereby rapidly and accurately confirming a calling party's telephone number in a remote place.
