Patent CA-2280828-C (CA)
Title: Pipe system cleaning and in-line treatment of spent cleaning solution
Inventor: FYFE EDWARD
IPC: C23G3/04
Filed: 1998-03-04
Granted: 2003-09-02
Abstract: A mobile cleaning unit (50) is connected to a fouled pipe (60) to be cleaned.  A pump (65) circulates cleaning solution from a reservoir (70) through an injection valve (80) in the mobile cleaning unit (50). The solution is regulated by diverter valves (85a, 85b) to an upstream valve (90), through the pipe (60), out a downstream valve (100), and through a return valve (110) to the reservoir (70). Treatment is monitored at either an upstream (115) or a downstream isolation valve (118). Spent solution is recirculated until it is environmentally safe for discharge out a drain valve (120). The process minimizes both the volume of treated spent solution and the treatment time.

Title: Device for carrying out continuous electrolytic precipitative deposition processes
Inventor: SCHNETTLER ROLAND
IPC: C25D7/06
Filed: 1998-04-11
Granted: 2003-10-07
Abstract: A device (1) for carrying out continuous electrolytic precipitation processes has a cathodic live cylinder (3) whose top surface is electrocon-ductive over its whole useful width. An anode A is arranged concentrically to and spaced apart from the cathodic live cylinder (3). An electrolyte flows through the space (6) separating the live cylinder (3) from the anode A. Shielding strips (9, 9') associated to the live cylinder (3) are located between the cathodic surface of the live cylinder (3) and the anode A and electrically shield the marginal regions of the live cylinder (3), thus pro-tecting them from electrolytic coating. The useful region N of the live cylinder (3) for carrying out the electrolytic precipitation processes is lo-cated between the shielding strips (9, 9'). The side of the shielding strips (9, 9') facing the useful region N has a shoulder (25') which reduces to zero the thickness of a metal strip to be produced or coated on one side, in the marginal region of the metal strip up to the shielding strip edge, so that no coating is deposited on the live cylinder outside the useful region N. The device (1) is useful both for electrolytically producing metal strips and for electrolytically coating one side of metal strips.

Patent CA-2292476-C (CA)
Inventor: SODREN CARL
IPC: H04W4/24
Filed: 1998-05-26
Granted: 2006-07-04
Abstract: A method (100) is disclosed such that when a call is being set up (104) from or to a mobile (or fixed) pre-paid subscriber, a portion of the value in the subscriber's pre-paid account is withdrawn (114, 120) to cover the cost of the call. Preferably, the amount withdrawn (114, 120) is large enough to cover the cost for a call of typical duration (e.g., 4 minutes). At call set up (104), for example, in an Intelligent Network (10), this amount is withdrawn (114, 120) from the account and allocated to the call being set up.      If this amount is not completely used up, the remainder is returned (146) to the pre-paid account. If, however, the allocated amount is depleted (124) before the call is completed, a second allocation or withdrawal from the account is requested for that call. If the value left in the account is large enough to cover the second withdrawal request, a second amount is withdrawn (114, 120) and allocated to cover the ongoing call. If needed, additional withdrawals (114, 120) can be made to cover the ongoing call until it is completed.      Once the call is completed (142), any remainder of the allocated amount is returned (146) to the pre-paid account. Consequently, a pre-paid subscriber can have a plurality of parallel ongoing calls, and because the amount in the pre-paid account is being monitored (116, 122) and accounted for before or while the calls occur, there is no risk that these calls will not be covered by the amount in the pre-paid account.

Abstract: A method and apparatus for generating an on-screen guide by which a user may select channels to view in a multiple channel broadcasting system are provided. According to one aspect of the invention, a program guide is generated comprising a number of still video pictures that represent current programming on a number of channels. The program guide is generated by the system tuning sequentially to each one of a number of channels. A visually usable video frame is captured from one of the number of channels.      The visually usable video frame is then decimated. Each of the steps of tuning, capturing, and decimating are then repeated for each of a selected number of channels. Following generation, the program guide is displayed on a screen or display. A system pointer is displayed on the screen along with the program guide, and the system pointer is manipulated in response to input by the user. A channel is selected for viewing by manipulating the system pointer to an area associated with the still video picture of the corresponding channel.
