Title: Treatment of gas streams
Inventor: WATSON RICHARD WILLIAM
IPC: C01B17/04
Filed: 1988-05-06
Granted: 1997-01-08
Abstract: A first hydrogen sulphide containing waste gas stream from an oil refinery is combusted in a first combustion chamber 16 using pure oxygen to support combustion. The combustion products are cooled in heat exchanger 20, and a part of the combustion products are recycled to the chamber 16 to moderate the temperature therein. The remainder of the combustion products are mixed with a second hydrogen sulphide containing waste gas stream of different composition from the first stream. A proportion of the hydrogen sulphide content of the mixed stream is combusted in combustion chamber 28 again using pure oxygen to support the combustion. The resulting sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapour.

Title: Signal multiplexing transmission device using multi-drop method
Inventor: PARK JONG-YOP
IPC: H04L5/00
Filed: 1991-10-02
Granted: 1995-04-13
Abstract: The transmitter includes a sending unit (1) having a number of sending modules (11-1N) interconnected with one another in parallel to send system control signals, a receiving unit (2) having a number of receiving modules (31-2N) interconnected with one another in parallel to drive the corresponding system in the module in accordance with the control signal from the sending unit (1), and a control unit (3) connected between the units (1) and (2) to receive the unit (1) signals to control the systems connected to the unit (2). The transmitter uses two communication lines to control the systems mounted in the modules.

Title: 무선전화기에서 통화전환시 라인 제어 방법
IPC: H04M3/58
Filed: 1991-10-25
Granted: 1999-04-01
Abstract: 무선전화기에 있어서 통화전원시 라인제어 방법에 관한 것으로, 특히 전화라인에 일반유선 전화기와 병렬접속(branch)하여 사용되는 무선전화기에 있어서 무선전화기에서 일반전화기로 통화를 전환할시 보류음악을 송출한 후 일정시간동안 통화절환이 이루어지지 않을 때 보류음악송출을 중단하고 통화라인을 차단하는 통화절환기 라인제어 방법에 관한 것이다. 
     전화라인에 일반유선전화기를 병렬 접속하여 사용하는 무선전화기에서 일반유선 전화기로 통화를 전환할 때 일정시간내에 통화전환이 이루어지지 않을 경우 통화라인을 끊음으로서 호출자의 통화료를 절감할 수 있고 라인의 원활한 소통을 보장받을 수 있다.

Abstract: 본 발명에 따른 자동차 주행방향 추정장치는 자동차의 속도와 가속도(Aw)를 계산하기 위한 바퀴속도계산기(6)를 갖춤과 더불어, 중력적으로 검출된 가속도(Am)를 생성하기 위한 중력식 가속도계(5)도 갖추고 있다. 그리고, 상기 양 가속도(Aw,Am)가 동시적으로 증가하거나 감소할 때에는 정방향 주행으로 판정하고, 상기 가속도(Aw,Am)중 어느 하나가 증가하면서 다른 것은 그 반대로 감소하는 경우에는 역방향 주행으로 판정하게 된다. 이와 같은 특성을 검출하기 위해, 상기 가속도(Aw,Am)의 미분 값(dAw,dAm)을 취하기 위한 계산기(9,10)가 제공되는 바, 상기 미분 값(dAw,dAm)을 이용함으로써 자동차 주행 방향이 추정되게 된다.
