Patent ES-8104561-A1 (ES)
Title: Semi-nondestructive residual stress measurement
IPC: G01L1/00
Filed: 1980-05-08
Abstract: Residual stress measurements are made using a strain gage and stress relief achieved by local melting of a region of the object being tested by a laser beam or other finely directed heat source. Surface strain is measured dynamically before the heat of the molten region diffuses under the gage and results in thermal stress. The method is semi-nondestructive because the molten region recasts with little loss of material, is rapid, and can be utilized on difficult geometries such as the interior surface of reactor pipe.

Patent ES-8303198-A1 (ES)
Title: A support device for the damaged wheel of a vehicle
IPC: B60B29/00
Filed: 1981-11-06
Abstract: A small, compact, fold-up three-wheel cart (carriage, bogie) which can be used to support a punctured or damaged wheel of a vehicle while the latter is being driven to a place of repair. The cart has a fold-up ramp which rests directly on the ground while the rear wheels are in a slightly raised position, so that it prevents the cart moving while the deflated tyre is being carried above it. As the ramp pivots upwards to a retention position behind the tyre, the rear wheels are lowered into a position of contact with the ground. Simultaneously, an extension connected to the ramp causes a retention member near the front of the cart to pivot upwards away from the path of the wheel to a front retention position. After mounting, the tyre rests in a cradle and is unable to move forwards or backwards with respect to the cart.

Patent ES-8302968-A1 (ES)
Title: Selective commutation circuit for an inverter.
IPC: H02M7/527
Filed: 1981-12-22
Abstract: A selective commutation technique used with an inverter eliminates one of the two commutation pulses at those points at which there is a particular relationship of inverter operating characteristics. The power factor angle theta , the voltage phase angle delta , and the voltage pattern notch angle beta are sensed to determine this particular relationship. Because at the switching point there is no current flowing through the gated thyristor, the gated thyristor can then be transitioned to the nonconducting state merely by the removal of its gate signal. A single makeup pulse is then rung through the system to initialize the commutation capacitors for the next switch point.
