Patent ES-8303229-A1 (ES)
Title: Container and closure therefor.
IPC: B65D47/14
Filed: 1981-09-25
Abstract: A closure for a container having a neck portion (38), a plug (28) which has a fluid-tight fit within the neck portion, and a manually openable pressure release valve (89) associated with said plug operative upon being opened to release the pressure in the container and also to condition the plug for relatively easy withdrawal to open position.

Patent ES-8307089-A1 (ES)
Title: Electrosurgical generator
IPC: A61B18/12
Filed: 1982-07-06
Abstract: A solid-state electrosurgical generator is disclosed which provides output waveforms that are optimized for electrosurgical fulguration. The fulguration output circuitry consists of a radio-frequency tank circuit which is periodically pulsed to produce a periodic damped-sinusoidal output waveform. However, the damping factor is sufficiently low so that many cycles of the waveform occur between periodic input pulses. Although the duty cycle is relatively high compared to prior art devices, cutting and burning effects are prevented by a high impedance output which internally limits fulguration arc current. The fulgurating arc developed by the device is longer and more consistent than that developed by previous devices thereby resulting in superior fulguration.

Title: Process for reducing phosphate ore.
IPC: C01B25/12
