Title: Laser joining method for galvanized steel sheets
Inventor: KEIICHIRO NAKAO
IPC: B23K103/04
Filed: 2017-11-08
Abstract: A method for joining galvanized steel sheets comprises a laser irradiation step and a roller pressurising step. The laser irradiation step includes; removing zinc plating layers PL respectively disposed on the surfaces of the galvanized steel sheets P by laser irradiation; and melting the surfaces of the galvanized steel sheets P of which the zinc plating layers PL have been removed. This is followed by the roller pressurisation step that includes pressurising the galvanized steel sheets P by rollers 21, 22 while the surfaces of the galvanized steel sheets P that have been melted are in contact with each other such that the sheets P are joined together. The focal point of the laser may be at a position where the sheets P are subject to pressurisation. The laser may remove the zinc plating at a first region of the sheet P and melt a portion of the sheet at a second region, the second region being within and smaller than the first region. The output of the laser may be increased at a centre part of the beam and lowered at a peripheral part of the beam. The method is stated to; i) suppress the occurrence of blowholes; ii) suppress the occurrence of through holes penetrating stacked galvanized steel sheets in the stacking direction, and; iii) reduce the energy required for laser irradiation for joining galvanized steel sheets compared to prior art methods.

Title: Measuring magnetic debris buildup in a magnetic filter
Inventor: SIMON DOWNIE
IPC: B03C1/00
Filed: 2017-10-02
Abstract: A magnetic debris level measuring device (10) for a magnetic filter (100) is disclosed. The magnetic debris level measuring device (10) includes a magnetometer and a temperature sensor (18). The temperature measured by the temperature sensor (18) is used to calculate a corrected magnetometer reading, which in turn can be used to determine the amount of captured magnetic debris held within the filter. The device (10) has a stored threshold for the corrected magnetometer reading, and when the corrected magnetometer reading crosses the stored threshold a notification is issued that the filter is full. If it is detected that debris continues to be captured after the 'full' notification has been issued, the stored threshold will be updated accordingly.
