Patent CA-1283191-C (CA)
Title: Method and apparatus for controlling hydraulic systems
Inventor: BACKE BENGT S
IPC: H02P8/14
Filed: 1985-09-04
Granted: 1991-04-16
Abstract: ABSTRACT OF THE DISCLOSURE      A control system is provided for a hydraulic actuating system having a multi-phase stepping motor with a driver therefor which supplies and controls DC current through each of the motor windings such that no current is induced into the control winding from adjacent windings.  The stepping motor precisely controls the rotation of an eccentric cam engaging an actuating plunger which actuates a control valve of the hydraulic actuating system.  The driver receives control signals from a computer programmed to calculate, from user input command signals indicative of the desired system condition, and generate those control signals which most quickly achieve a rough approximation of the desired system condition.  After this rough approximation is attained, the computer generates new control signals for the driver as a function of feedback signals and/or system component characteristics so as to precisely achieve the desired system condition.

Title: Process for increasing the concentration of one component in a multi-component gaseous mixture
Inventor: BERRY W WES
IPC: B01D53/04
Filed: 1985-11-15
Granted: 1991-10-15
Abstract: ABSTRACT OF THE DISCLOSURE         A process for enhancing the concentration of one component contained in a multi-component gas is disclosed which is particularly well-suited for enrich-ing the oxygen content of air.  The process is carried out by a series of adsorption and desorption stages using an Advanced Separation Device comprised of a plurality of adsorbent-filled chambers moving about a circular path in periodic fluid communication with a plurality of fixed feed and discharge ports.  By using the Advanced Separation Device, it is possible to load the oxygen content of air onto the adsorbent which is then stripped by a second stream of air.  This oxygen-enriched stream of air may then be divided so that the oxygen content of one stream may be adsorbed for subsequent removal by the other stream to produce a doubly-enriched stream.

Title: Water tower
Inventor: RAIKAMO MIKKO H
IPC: E04H12/30
Filed: 1986-11-28
Granted: 1990-12-27
Abstract: ABSTRACT OF DISCLOSURE            A  water  tower  consisting of a  main body  extending upward from the ground,  a water channel and a pumping means for pumping water into the water channel,  which acts as a water storage of the tower.  In known water towers, the main water storage is placed at the top of the tower,  at a height of several  tens  of  meters,   which  means  that  the  costs  of construction of the tower and its groundwork are consider-able and impose  strict requirements on the structure of the tower.  These problems are solved by the invention in that the tower is provided with a water reservoir placed at its lower end under the ground surface or substantially close to the ground  surface,   said  reservoir constituting a  safety storage of water, and that the water channel of the tower is of a substantially narrow sectional form through the whole of its length.

Granted: 1990-10-30
Abstract: ABSTRACT OF THE DISCLOSURE         This specification teaches a method of making an electrically heated, glass vision unit having a complex curved configuration.  The method is initiated by cutting a glass substrate (10) from a flat glass bracket (12). The glass substrate (10) has first and second surfaces separated by a uniform distance.  A pair of electrically conductive bus bars (16-16) are applied to one of the surfaces of the glass substrate (10).  The bus bars (16-16) are so positioned on the flat glass substrate (10) that when the substrate (10) is bent to form the glass vision unit of complex curved configuration, the pair of electrically conductive bus bars (16-16) are equally distant from one another throughout their entire extent.  The flat glass substrate (10) is bent to form the glass vision unit of complex curved configuration.  A conductive coating (20) is applied to the one surface of the glass substrate (10) and extends between the pair of bus bars (16-16) throughout their entire extent.  In this manner, when electrical energy is applied to the bus bars (16-16), a uniform flow of current takes place from one bus bar to another bus bar so that a uniformly developed heating pattern is established between the bus bars (16-16).  The steps of bending the flat glass substrate and applying the conductive coating may be interchanged.
