Title: Mechanism for forming a Fibrous Web
IPC: D21F9/00
Filed: 1967-09-12
Abstract: A mechanism for forming a fibrous web comprises a breast roll 11 with a suction gland 12 within it, a press roll 15 with a suction gland 17 within it, spaced slightly from the breast roll, an endless forming wire 10 wrapped under tension around both rolls, an endless felt 16 wrapped around the press roll beneath the wire, and means 13 depositing a fibrous slurry on the wire opposite the suction gland in the breast roll. As shown, there are two suction glands 17 and 18 within the press roll, the second applying greater suction than the first a saveall 19 catches water flung centrifugally from the wire and the web is carried by the felt 16 from, the press roll 15 to the nip between further press rolls 24 and 25 of which the latter has a suction gland 27, then by the roll 24 to its nip with a press roll 26 with a suction gland 28 and a felt 29. In a second embodiment (Fig. 2, not shown) the coach and first press rolls are horizontally opposite each other and the saveall beneath them, and the felt carries the web directly from the press roll to a Yankee drier, on to which it is pressed by a second press roll with a suction gland within it.

Patent ES-428639-A1 (ES)
Title: Automatic pistol
IPC: F41A19/46
Filed: 1974-07-26
Abstract: An improved automatic pistol is provided with a lever mechanism which causes operation as a burst-firing arm in a safe and reliable manner. This is achieved by forming the disconnector, which releases the sear, with a chamfered and bent end, opposite to the end engaging said sear, in order to co-operate with a trigger bar which has two degrees of freedom in the usual repeating operation, and which is connected in an articulated manner to the pistol trigger. Through a 90 DEG rotation of a selector member, a should on the trigger bar allows the trigger bar only one degree of freedom thus causing the disconnector, which is pivotedly mounted on the reciprocating breech mechanism, to enter into a tangential, instead of perpendicular contact through its bent and chamfered end with the trigger bar. Thus, the disconnector enables continuous firing of the pistol as long as the trigger remains is pressed. The breech mechanism is provided with a number of air intakes and is preferably of frusto-pyramidal shape for cooling the piston barrel.

Title: Process and device for analizing and validating signals usable in warning systems for road-signs
IPC: E01F9/529
Filed: 1974-12-05
Abstract: Two orientated magnetic field generating means such as permanent magnets are embedded in a roadway at some distance from each other before a road-sign, said magnets extending on the whole width of the roadway. When a vehicle equipped with a detector crosses said magnets, signals of pseudo-sinusoidal shape are generated. Said signals are applied to elements converting them to calibrated pulses corresponding to the two alternations of the signals. The order of said ulses is checked to validate only pulses appearing in a predetermined order, thus eliminating direction ambiguity. The time separating two pulses is also checked to validate only pairs of pulses comprised in a predetermined time period, thus eliminating interferences from outside. The pairs of pulses are transmitted to at least one time window circuit which is adjusted to a predetermined period of time. Only pairs of pulses appearing within said predetermined period are validated. Said pairs of pulses are counted and their number is compared with a predetermined number they are then transmitted to a warning device. By providing two time window circuits adjusted to different periods of time, the system can be used both for indicating road-signs and as a kinemometer, the two magnets being then separated by a distance which is a function of the authorized speed.
Patent ES-436082-A1 (ES)
Title: Methods of and apparatus for controlling the thickness of an annular extrusion
IPC: B29C48/92
Filed: 1975-03-26
Abstract: A cable core advances through an extruder head and then past an ultrasonic test set. In the extruder head, an annular plastic jacket is formed about the core. The test set generates four signals which correspond in magnitude to the jacket thickness in orthogonally spaced quadrants of the jacket. The signals are then applied to apparatus for centering the core with respect to the extruder head. Additional apparatus generates control signals in response to the signals from the test set. The control signals are applied to a mechanism for adjusting the jacket thickness in diametrically opposite quadrants with respect to the thickness in the quadrants adjacent thereto to control the uniformity of the jacket thickness. The control signals are also applied to a mechanism for controlling the overall jacket thickness. The signals give priority to the function of controlling the uniformity of the jacket thickness before the overall jacket thickness is reduced to a predetermined thickness range. A special control signal overrides other signals for controlling the jacket thickness and causes an increase in the overall jacket thickness whenever the jacket thickness in any of the quadrants falls below a predetermined minimum thickness.

Patent ES-448312-A1 (ES)
Title: Digital communications system with immunity to frequency selective fading
IPC: H04B7/22
Filed: 1976-05-28
Abstract: A digital communications system with increased resistance to frequency selective fading. Digital signals to be transmitted are phase shift modulated upon a spectrum spreaded carrier. The carrier is generated by mixing the output of a band spread oscillator with a locally generated IF oscillator signal. The signal thus obtained is divided into transmission periods, each of which is longer than the maximum spreading time of the nonlinear transmission medium. The increased bandwidth occupancy thus obtained increases the immunity of the transmitted signals to frequency selective fades moving across the allocated bandwidth. The signals are received by a differentially adaptive receiver which automatically adjusts its response to the envelope of received signals.
