Granted: 1988-08-24
Abstract: A singal input (21) is applied to an absolute value detector (20) whose output drives a logarithmic gain amplifier (31, 32) before passing through an amplifier (33) to a logarithmic compression level detector (30).  In the detector a diode (34) connects the signal to an integration capacitor (35).  A current source (36) provides a reference current (Io).  A diode (43) compensates for the voltage drop of the integration ciruit diode to apply the signal to a voltage probe amplifier (45).  A current source (44) provides a reference current for this current.  A voltage divider (46) at the amplifier output is also connected to the intergration circuit amplifier (40) to allow a feedback signal to be passed to the detector input.

Abstract: The appts. is taught and has a movable stem interconnected with one of the separable main contacts.  Flat planer flexible conductors connected in parallel circuit relationship between the stem and a fixed terminal for the circuit interrupter system are utilised. Planar members are spaced from each other for enhanced heat dissipation characteristics.  The planar members are generally self- supporting except for the flexibility associated with a particular shape, consequently are not likely to randomly touch other appts. in a switchgear cabinet.  Nevertheless, the amount of conductor represented by the parallel planar members is sufficient to conduct electrical current when the circuit interrupter is closed.

Title: Prepararing method of barley for barley tea
Inventor: CHONG IN-TAEK
IPC: A23L7/196
Filed: 1982-11-03
Granted: 1984-12-27
Abstract: By extracting nutritious substances from barley to the maximum extent, a barley tea is produced that is thick in taste and aroma as well as sanitary.  After segregating barley 1 or 2 times through a barley-cleaning machine the grains are heated by rotation for 3-5 minutes with many granite particles pre-heated to 150-250≰C in the first thermo plastic machine.  With this process, the hard peel of the barley can be removed by radiant heat of the granite particles. The hard peel and inner part of the barley turn a light brown color if heated indirectly to 150-300≰C for 5-10 minutes in the second thermo plastic machine after removing granite particles.

Inventor: ESCHMANN JOACHIM
IPC: H04M3/56
Filed: 1982-12-07
Granted: 1988-10-17
Abstract: A binary pulse train enters a serial to parallel converter from which the signals pass through a suppression circuit to an evaluation circuit and buffer.  A speech sample comparator provides comparision of all the conference speech samples by groups. Counters are updated by the loudest participants' signal and their outputs are compared to issue control signals for an attenuation controller.  A code converter converts speech samples coded in non-linear fashion and also linear coded signals.  The speech samples are then added and the results stored temporarily in an accumulator.  A second converter converts the signals to conversation signals before being transferred through a parallel to serial converter to the transmission line.

Patent KR-920009725-B1 (KR)
Title: Catv system
Inventor: PARK SUNG-RYONG
IPC: H04N7/10
Filed: 1988-11-04
Granted: 1992-10-22
Abstract: The apparatus is for selecting a channel band and for locking phase of frequency  of  the  corresponding  channel  when  channel change key  signal  is  received.  The   apparatus   includes   a microprocessor for generating control signal to select  a  channel band, a gand selector for transmitting band selection signal to  a tuner,  a  pre-scaler  for  decreasing  the  frequency  of   local frequency signal generated by a tuner,  a  frequency  divider  for dividing the  local  frequency  according  to  the  dividing  data transmitted from  the  microprocess  and  for  generating  divided frequency of the selected channel, a reference frequency generator for  generating  reference  frequency,  a  frequency   and   phase comparator for detecting phase and frequency  error,  and  a  loop filter for feeding the error signal back to the tuner so that  the divided frequency is locked to the reference frequency.
