Title: Underwater communications device.
IPC: G10K13/00
Filed: 1978-12-19
Abstract: A communications device for use under water by a human speaker. A tubular base member has a mouthpiece located at one open end thereof and an inflatable air bag mounted about another open end thereof. In use, the speaker places the mouthpiece around his mouth to form an air seal therebetween and blows into the air bag to partially inflate it. When so inflated, the speaker talks into the device with voiced sounds being transmitted to the surrounding water through suitable transmitting means attached to the base member, preferably the air bag itself. During talking, the air bag receives and returns the air used by the speaker, thereby effectively preventing the escape of air bubbles from the device which otherwise interfere with communications. The air bag is preferably an elongated, flexible balloon which can be stretched into an extended position when speaking into it under water.

Patent ES-8107395-A1 (ES)
Title: Digital AGC circuit for radar target detector - has gain controlled from memorised signal from counter and digital integrator circuits
IPC: G01S7/34
Filed: 1980-10-09
Abstract: The detection is achieved by automatic control of video frequency receiver gain using a memory system. The memory contents are derived from integration of successive recurrences of the radar signals. A gain control circuit comprises a threshold circuit (2) which receives video frequency signals from a variable gain amplifier (1). If the received signals exceed a threshold value then clock signals are applied to a counter (3) and the number of pulses in a time period is applied to a subtraction circuit (4). This produces an output (No) which determines the mean noise value. The resultant output is applied to an integrator (5) containing read and write memories. This allows the new values of pulses from the counter to be stored for application to the variable gain amplifier via a D/A converter (62) to change the gain.

Patent ES-8205647-A1 (ES)
Title: Method of manufacturing a pack for ovoidal objects
IPC: B31B11/00
Filed: 1981-04-08
Abstract: A cardboard pack for eggs, or the like, is made of two slitted blanks, the longer one of which is bent into flat-topped and flat-bottomed waves. After the wave bottoms are bonded by adhesive to the flat blank, the wave tops are tucked in and the waves flattened mechanically. After the adhesive bonding, the solid cross-strips at the ends of the flat blanks become unnecessary and are cut off. Precautions are taken to avoid undesired adhesion of strips previously separated by slitting. With the waves flattened, the blanks can be easily stored or transported. The blanks are set up at the place of filling by mechanically raising the waves, bending up the sides of the back to form pockets, inserting the goods, bending over the top strips, and securing them together on their line of abutment. The shorter set of blanks is preprinted.
