Title: Method of electrolyzing halides
Inventor: DENORA ORONZIO
IPC: C25B1/24
Filed: 1983-07-19
Granted: 1984-12-15
Abstract: An electrolytic cell, partic. for chlorine prodn. includes a flexible ion-permeable draphragm with a compliant electrode layer on one or both side and a current distributor bearing against the layer. The distributor or a counter-electrode on the other side of the diaphragm is a resiliently compressible mat coextensive with the electrode. The mat applies pressure at multiple points so that equalising pressure is made by transferring excess from one point to adjacent points. The mat is open to permit electrolyte flow.

Title: Method for driving a gas discharge panel
Inventor: SHINODA SUDAEU
IPC: G09G3/28
Filed: 1985-03-15
Granted: 1989-07-10
Abstract: A firing voltage is applied across a display electrode pair to generate discharges in the display cells, defined by the display electrode pair.  A discharge is generated in select cells corresp. to non-selected display cells, thus eliminating the wall charge and erasing the non-selected display cells.  An asymmetrical composite sustaining voltage is applied so that the amplitude of the sustaining voltage is applied to one display electrode which defines the select cell, larger than the amplitude of the sustaining  voltage applied to the other display electrode. The sustaining voltage across the electrode pair maintains discharges in the selected display cells.

Title: Computer controlled lightning system with distributed processing
Inventor: TAYLOR BROOKS W
IPC: G05B19/042
Filed: 1987-07-16
Granted: 1991-07-22
Abstract: A stage lighting system has a plurality of automated lamp units which can vary the parameters of a light beam for pan, tilt, brightness, intensity and size. A control console is connected to each of the lamp units via a data link. Each of the lamp units includes a microprocessor and a memory. Control programs for driving each of the lamp parameters are stored in the memory and are executed by the lamp microprocessor. The console includes a microprocessor as well as memory. Commands are input through the console to change the effect produced by the lighting system. Each of these changes is directed to all of the lamp units. Each lamp unit responds individually and independently to change the light parameters based upon its own operating programs and the data condition of the lamp at the time that the change was made. Each of the lamps further stores a unique lamp cue which corresponds to a system cue that is stored in the memory of the console. When a new system cue is selected at the console, this system cue is directed to each of the lamp units which then recall their independent corresponding lamp cues and set the lighting parameters of each individual lamp. The transmission of numbered cues and change conditions substantially reduces the amount of data that must be transmitted through the data link. Additional lamp units can be easily added to the system without adding to the workload of the central processor or the data that must be transmitted through the data link.

Abstract: 본 발명은 키폰 전화기의 다이얼링 기능에 관한 것으로 통화하고자 하는 상대방이 다수의 전화번호를 갖는 경우 일일이 다이얼링하지 않고 자동으로 비통화중인 전화번호의 통화로와 연결되도록 하는 키폰 전화기의 자동 다이얼링 방법에 관한 것이다. 
     종래의 키폰 전화기에서는 통화를 하고자 하는 키폰 사용자가 전화를 걸어 통화중이면 상대방이 갖고 있는 다수의 전화번호중 다른 전화번호를 다시 다이얼링하게 되고, 또 다시 통화 중인 경우 또 다른전화번호 또는 처음 다이얼링한 전화번호를 재다이얼링해야하는 번거로움이 있다. 
     본 발명은 동일한 상대방을 갖는 다수의 전화번호를 하나의 그룹으로 하여 한 그룹내의 임의의 전화번호를 다이얼링했을 때 통화중인 경우 해당 그룹내의 모든 전화번호를 자동으로 순차적으로 다이얼링하여 비통화 중인 통화로를 연결시켜 주므로써 종래에 해당 그룹의 다수의 전화번호를 일일이 수동으로 다이얼링해야 하는 번거로움을 없앨수 있어 전화기 사용상의 편리성을 증가시키게 된다.

Abstract: 본 발명은 홈롤에 의한 선재의 압연장치를 개랑한 것이다. 
     본 발명은 외주면상에 홈을 가진 여러개의 홈롤을 서로 맞대어서 생긴 공간부에 선재를 삽통시켜 압연하는 장치에 있어서, 상기 홈롤에 압착되어 구동력을 전달시키는 백업롤을 가지며, 상기 홈롤은 종동롤러가 되도록 하며, 그리고 상기 백업롤의 중심에 대하여 홈롤의 중심이 선재의 송출방향으로 오프셋트 되어 있음을 특징으로 한다. 
     본 발명은 홈롤의 교채가 용이하며 장치가 매우 간단하고 홈롤의 직경을 종래보다 적게 할 수 있어서 소성가공에너지를 감소시킬 수 있도록 된 것이다.
