Title: Asynchronous operation of cycloconverter with improved voltage gain by employing a scalar control algorithm
Inventor: ROY GILLES
IPC: H02M5/27
Filed: 1987-10-20
Granted: 1992-08-18
Abstract: ASYNCHRONOUS OPERATION OF CYCLOCONVERTER     WITH IMPROVED VOLTAGE GAIN BY EMPLOYING                   A SCALAR CONTROL ALGORITHM     ABSTRACT     This  proposes  a  direct  frequency  changer  made of a matrix of bidirectional switches which interconnect a  three phase  input  AC  input voltage system to a polyphase output voltage system in  which  the  conduction  periods  of  each switch  are governed by a scalar control method.  The method uses the instantaneous voltage ratio of specific input phase voltages  to  the  switches  to generate the active and zero states of said switches. A voltage transfert ratio  as  high as  0.87  is  attainable  under synchronous and asynchronous operation with conventionally connected  three  phase  load.          Moreover,  the  converter  operation  can  be set to produce almost any power  displacement  factor,  as  seen  from  the input,  independently  of  load  power factor.  Finally, the method allows using simple analogue and  digital 'techniques to  implement  the matrix controller as no complex equations have to be solved on line.

Patent CA-1290455-C (CA)
Inventor: CHANG PHILIP Y
IPC: G06F/
Filed: 1989-01-27
Granted: 1991-10-08
Abstract: ABSTRACT OF THE DISCLOSURE     In the relational database system of the present invention, an extension to the SQL language is provid-ed to allow a user/application to specify whether a column in a database table contains only single byte character set data, or mixed single byte character set data and double byte character set data. Specifying whether a column contains single byte character set data or mixed data is achieved by specifying the subtype of the character data types including CHAR, VARCHAR, and LONG VARCHAR.  The user application can specify the subtype of character data within a column as the column is created or added by specifying FOR SBCS or FOR MIXED in either the CREATE TABLE statement or the ALTER TABLE statement.     Along with specifying the subtype as either for single byte data or for mixed data, the us-er/application can further specify the codepage to be used for the column of the table in the database. Internally within the database manager of this inven-tion, the subtype is recorded in terms of the code page attributes of the character data type as stored in the database system catalogs.  This encoding scheme provides an efficient method of determining whether a column is only for single byte character set data or mixed data, and at the same time knowing the correct codepage that is to be used for that column simply by querying the code page columns within the database system catalogs.

Title: Reference electrode
Inventor: LAUKS IMANTS R
IPC: G01N27/416
Filed: 1989-02-07
Granted: 1991-03-05
Abstract: ABSTRACT OF THE DISCLOSURE           An improved reference electrode is disclosed for use in potentiometric measurements of the amount of ions in an aqueous solution.  The reference electrode illustratively comprises a metal member on a substrate and a layer of a salt reversible to the ion X overlying the metal member. The reference electrode is overlaid by a quantity of an electrolyte, which may be a polymer gel having a salt including the ion X dispersed therein.  This structure is overlaid by a membrane permeable to water but not to the ion X that extends beyond the portion of the electrolyte overlying the electrode, but leaves a portion of the electrolyte exposed.  This assembly may be shipped dry.  In use, when the electrode is disposed in an aqueous solution containing an ionic species to be measured, water permeates the membrane and "wets up" the electrolyte relatively quickly.  Any changes in ionic concentration, however, have to be made over a substantially longer path through the electrolyte between the electrode and the exposed portion such that the transit time for such changes is substantially longer than the wet-up time of the electrolyte.  This reference electrode may he used in combination with a wide variety of potentiometric indicating electrodes or other structures.

Title: Telescoping actuator for impulsive seismic source
Inventor: AIRHART TOM P
IPC: G01V1/147
Filed: 1989-03-03
Granted: 1992-11-10
Abstract: ABSTRACT          An impact type surface seismic source powered by compressed air includes an elongated piston which moves within the bore of a cylindrical firing tube suitably mounted above an earth contacting target.  The firing tube consists of two or more tubular sections slidably joined in telescopic relation.  When the piston is allowed to fall from a cocked position, compressed air enters the bore above the piston through side ports and drives the piston downwardly.  At the same time, the inner sliding section or sections of the firing tube are exposed to the same air pressure within the bore and are also driven downwardly.  In this way, the bore of the firing tube lengthens automatically to provide a longer stroke for the piston and thus a greater attained kinetic energy of impact for a given operating pressure as the piston reaches the target.  The apparatus is designed for mounting on a transport vehicle so that the firing tube itself may be raised in operation and lowered for reduced vehicle profile during transport.
