Patent CA-2139911-A1 (CA)
Title: Class ab push-pull drive circuit, drive method therefor and class ab electronic circuit using the same
Inventor: YAMASHITA KAZUO
IPC: H03F1/30
Filed: 1995-01-10
Abstract: A class AB push-pull drive circuit has two NPN transistors Q1, Q2 and two PNP transistors Q3, Q4, the emitters of which are connected together. A constant voltage circuit maintains voltages between the bases of transistors Q1 and Q3 and between the bases of transistors Q2 and Q4 constant. A differential input voltage is applied across the bases of the transistors Q1 and Q2. The collector currents in the transistors Q1, Q3, Q2 and Q4 increase or decrease in an exponential and differential manner. When the collector currents are in their differential relationship, they are inverted and added to provide a class AB drive current and to increase the output amplitude. The symmetry can also be improved.          Since any difference between signal amplification path lengths is eliminated, a differential phase between paths is less likely to be generated in the high-frequency region. Since there is no feedback or the like for class AB drive, it is difficult for any abnormal oscillation to be produced. Since the constant voltage circuits are formed by diodes, the temperature characteristics of the transistors Q1 to Q4 can be compensated. Furthermore, the class AB push-pull drive circuit can be driven by a relatively low voltage. The bipolar transistors Q1 - Q4 may be replaced by FETs.

Title: Iodine/resin disinfectant and a procedure for the preparation thereof
Inventor: MESSIER PIERRE JEAN
IPC: A61P31/04
Filed: 1993-09-15
Abstract: The present invention relates to iodine demand disinfectants. It relates in particular to a process for preparing a polyiodide-resin for use as a iodine demand disinfectant wherein a porous strong base anion exchange resin in a salt form, is contacted with a material capable of donating a member absorbable by the resin so as to convert the resin to the polyiodide-resin. The adsorbable member is selected from the group comprising I 2, and polyiodide ion having a valence of - 1. The process is characterized in that conversion of the anion exchange resin to the polyiodide resin is effected at elevated temperature and elevated pressure, the elevated temperature being 100 °C or higher, the elevated pressure being greater than atmospheric pressure. The present invention also relates to a disinfectant substance comprising an iodine (impregnated) resin as produced by the above process.

Patent CA-2141727-A1 (CA)
Inventor: ANDERSON THOMAS W
IPC: H04L12/56
Filed: 1995-02-02
Abstract: A conference bridge that receives speech data in the form of data packets, and transmits data in the same form, without transforming the data in the conference bridge. The conference bridge according to this invention includes a plurality of inputs that have speech detectors that detect the presence of speech data. The speech detectors report the presence of speech to a controller. The controller causes data packets from one of the inputs detecting speech to be replicated for all outputs. If there is speech at more than one input at a time, then a decision is made as to which input to replicate. Advantageously, the decision is based on who is the loudest speaker. Further, the data that is replicated is not sent to the output for the originator in order to prevent echo.
