Patent ES-450778-A1 (ES)
Title: Method and apparatus for evaluating welds using stress-wave emission techniques
IPC: B23K31/00
Filed: 1976-08-18
Abstract: Spot welds are evaluated using stress-wave emission techniques by measuring the stress-wave energy emitted from the weld area during n time intervals of the weld cycle, where n>/=4. Each of the time intervals corresponds to a different aspect of the weld cycle such as, for example, the initiation of heating, the separate solid-to-liquid phase transformation in each of the articles being welded, material combination within the weld nugget, cooling stresses occurring during resolidification, and post-weld cracking. The energy values obtained for each of the time interval can be compared with predetermined acceptable energy value ranges for corresponding ones of the intervals and/or compared with predetermined ratio values between two or more of the obtained interval values to determine the quality of a weld.

Title: A pneumatic device for moving and placing loads.
IPC: B66F/
Filed: 1979-01-18
Abstract: The purpose of this invention is to provide a device for moving and placing frames in currently-operating or new telephone exchanges, which totally solves the aforementioned difficulties, facilitating the movement and positioning of the load in its exact place, using just one man exerting barely any effort. The invention is based on separating the load from the floor by means of a sheet of air which enables the load to slide above it, with no friction whatsoever with the floor. To this end, one or more bags with perforations are simply situated appropriately below the load and air is continuously blown into them at suitable pressure so that, as it exits through the perforations, the load is raised, with the air escaping underneath the load creating a sheet above which the load slides with a normal, light push. The invention is complemented by a mechanism designed to prevent a load which has a high centre of gravity from tilting.
