Patent ES-429114-A1 (ES)
Title: Transit exchange for asynchronous data with unknown structure
IPC: H04L12/52
Filed: 1974-08-09
Abstract: The present invention relates to a transit exchange for the transmission of asynchronous data signals having an unknown character structure and data rate with the aid of a control equipment including a processor and a sampling device which is common to a number of sending terminal equipments and which works on the time multiplex principle. The data signals received on each of a number of incoming lines are sampled at a frequency so selected in relation to the data rate, expressed in unit elements per second, that the number of sampling pulses per unit element of the data signals is not less than the reciprocal value of the permitted relative time distortion. The transit exchange includes an encoder working synchronously with the sampling device which, when detecting a change of value of the data signals, delivers a code word comprising a specific number of bits indicating the time position for the change to an intermediate memory where the code word is stored one bit at a time in an address assigned to the receiving terminal equipment. It further includes a decoding device which, by successive processing of the bits of the code word, forms indication signals which alter their value at time positions corresponding to the code word, and also includes a read-out device which transfers the values of the indication signals to a regeneration device corresponding to the receiving terminal equipment where data signals are formed which change their value in synchronism with the indication signals.

Patent ES-465132-A1 (ES)
Title: Process and apparatus for the manufacture of fibres from attenuable materials
IPC: D01D5/08
Filed: 1977-12-16
Abstract: A gas jet emitter (20) emits, through a series of orifices (21), a row of gas jets which are diverted and spread by a deflecting plate (40). The spreading of the jets is however limited by impact with the adjacent jets, which gives rise in each jet to counter-rotatary vortices (45, 48) surrounding a laminar flow zone (44) at low pressure, into which a thin stream (S) of molten thermoplastic material is sent. The jets are directed against a main gaseous flow (18) into which they penetrate, forming interaction zones. The thin streams are thus stretched successively in two steps, but the second step may be omitted. The method applies in particular to manufacturing glass fibres.

Title: Apparatus for removing appendages from avian species by using electrodes to induce a current through the appendage
IPC: A61D1/00
Filed: 1979-01-11
Abstract: A method and apparatus for removing appendage tissue from avian species such as domestic fowl and principally from commercial chickens and turkeys is disclosed. When the appendage is the beak, the method is known as debeaking and the invention is a method comprised of the step of burning and simultaneously cauterizing a hole through a portion of a bird's beak in order to damage the tissue and precipitate eventual rejection thereof outwardly from the point of damage, and apparatus which includes means adapted to position the bird's beak between and in contact with opposing electrodes projecting into the apparatus which effect the burning as aforesaid. A power source for the electrodes providing an open circuit voltage of sufficient magnitude to initiate current flow through the beak when opposing sides of the beak contact the electrodes. With current flow initiated, the power souce current increases toward a maximum short circuit value sufficient to cause burning of the portion of the beak between the electrodes, while the voltage drops to a value sufficient to maintain the desired current. The preferred control for the power source determines a time integral of current flowing through the bird's beak and, upon reaching a predetermined time integral of current value, the control de-energizes the power source.

Title: Automatic apparatus for continuously forming cloth rolls
IPC: B65H19/22
Filed: 1979-11-28
Abstract: An automatic apparatus for continuously forming cloth rolls of a selected length from great size rolls or continuous bands made of a number of cloth pieces sewn together, comprises a detecting means such as a photocell responsive to a seam between two adjoining pieces, positioned upstream of a measuring station which in turn is upstream of a cutting station. Selected advancements of the cloth and corresponding cutting operations are actuated by known automatic devices which are disabled whenever the above-mentioned detecting means senses a seam between two pieces sewn together. Another detecting means such as photocell in correspondence of the measuring station causes the cloth to stop as soon as a seam has reached this position, being preset to this operation by the first-mentioned photocell. With the automatic advancement disabled, the cloth is caused to advance, after the stop, by a fixed length corresponding to the distance between the measuring station and the cutting station. A tube feeding station is also provided for supplying each time a tube being the core of a new roll to be formed, from a tube magazine at a winding station. There are also provided devices for bending the leading edge of the cut cloth around an empty tube, causing this edge to adhere thereon without formation of pleats and discharging finished roll.
