Patent CA-2197565-A1 (CA)
Inventor: KIRCHNER EDUARD
IPC: B23K9/20
Filed: 1995-06-15
Abstract: The device proposed is designed to weld together at least two parts (1, 2) using arc-welding or resistance-welding, in particular pressure arc-welding, techniques.      An arc is struck across a gap between the two parts (1 and 2), thus causing them to melt.      In oder to ensure a very precisely defined vertical gap between the parts, the second part (2) is first placed on the first. The final position, determined by a programme-control unit (12), is measured by means of a travel-measurement instrument (10). Starting from this "zero position", the bolt is lifted through a freely programmable distance and the main welding current activated. On expiry of the prescribed period of time, the bolt on the second part (2) is moved towards the first part (1), this movement also being carried out under programme control.

Title: System and method for verification of electronic television program guide data
Inventor: COLLINS DEBBIE
IPC: H04N7/16
Filed: 1995-10-27
Abstract: The system and method of the present invention provides for automated checking of the program listings data in a database of television program schedule listings used in an electronic program guide ("EPG"). The disclosed invention provides a system and method for verification of the EPG data prior to transmission to a cable or other pay television system (or prior to transmission to viewers).

Abstract: An electrode for attachment to a patient comprises a flexible planar member, an electrically conductive member embedded in said flexible member and adapted for contact with the patient, a layer of electrically conductive adhesive applied to the conductive member and the flexible planar member on a side of the flexible planar member facing the patient. Through holes extend completely through the electrode and, optionally, may also extend through the layer of adhesive. Alternatively, a permeable electrode having a permeable member which allows a solvent to pass through to the adhesive may be used to eliminate the need for through holes in the electrode. The permeable electrode may also be coated with sodium chloride or potassium chloride and used in conjunction with an applicatorcontaining an alcohol gel which liquefies upon contact with the sodium chloride or potassium chloride. A transdermal patch comprises a layer or compartment where the medication is stored and a layer of adhesive through which the medication diffuses. Again, a plurality of through holes are formed completely through the product and, optionally, through the adhesive as well. An applicator containing the solvent can be placed in direct contact with the top of the electrode or the top of the transdermal patch. In this manner, the solvent can be directed through the through holes formed in either the electrode or the patch to release the solvent and to facilitate its removal.
