Title: Optical system for the remote position-indication of a moving element
IPC: G01D5/347
Filed: 1967-05-16
Abstract: A system for the remote position indication of a moving element e.g. an element of a nuclearreactor re-charging system includes a member having coded parallel tracks e.g. as in Fig. 2, the member being driven in synchronism with the element between a fixed light source and a photo-electric detector, a selector, e.g. a disc as in Fig. 3, uncovering the tracks in succession so that the output from the detector is a plurality of markings serially transmitted. The selector and coded member each have a supplementary track with markings which, when they coincide allow light to pass to a further photo-electric detector to enable the output from the first detector to be read. In the embodiment described, both the angular position of a bridge 12 (Fig. 1) and the linear position of a carriage 14 on the bridge 12 are read by means of binary coded members sensed by photo-oells as selectors rotate. The output from photo-cell 26 representing the angular position of the bridge is fed to a store 52 which controls a display system 54 and if it is required to position the bridge in accordance with a position entered via a keyboard 60, the output from the store and keyboard are fed to a comparator 62 the output from which stops the motor driving the bridge when coincidence is reached. The carriage may be similarly positioned. The coded member for the carriage is an endless belt having parallel longitudinal tracks, a selector disc scanning the tracks sequentially. The selector disc may be replaced by a drum.

Patent ES-360095-A1 (ES)
Title: Overload monitor for transmission systems
IPC: H04J1/16
Filed: 1968-10-25
Abstract: In a frequency division multiplex communication system a group of channels, e.g. in the band 60 to 108 kHz, has the power level monitored by a narrow band pass filter which is arranged to be swept across the frequency band of the channel group, the rate of sweep being controlled inversely with the filter output. Completion of a sweep across a group of channels is arranged to reset a timing device and to switch the monitoring arrangement to another group of channels. If the sweep is not completed within a predetermined time, set by the timing device, an alarm is given indicating that a fault exists in that group of channels. Fig. 1 indicates a system in which the output of one of a number of groups of channels each of frequency range 60 to 108kHz is connected via a stepping switch 12 to a modulator 11 which, being fed with a carrier which is swept over the range 110 to 158 kHz, transposes the input signal to sweep across the pass band of the filter 14, i.e. 1 kHz at 50 kHz. The output of the filter is rectified and filtered to provide a signal to control the rate of sweep of the sweep generator 17, reducing the rate as the signal level increases. The output from the sweep generator is fed to control the frequency of the carrier oscillator 13, and also to a Schmitt trigger 18 which fires and actuates a reset relay 19 when the sweep generator reaches a voltage corresponding to the completion of a sweep. The reset relay causes resetting of the sweep generator 17 to the sweep start position, resetting of the timer to its initial condition, and operation of the stepping switch to connect a different group of channels to the modulator 11. If, due to overloading of the channel signals, the sweep is not completed before timer 20 has timed out the timer produces an output signal which actuates, via switch 22, the appropriate one of the alarm relays R1 to Rn which magnetically holds until manually reset. The timer also actuates the Schmitt trigger to operate the reset relay so that monitoring of the other groups of channels may continue. Fig. 3 shows the sweep generator circuit in which a capacitor V c is connected in a "bootstrap" circuit to charge linearly via transistor 34 and resistor 35. The output of the rectifier filter circuit causes a variable shunt to be placed across the capacitor V c to control the rate of charge in dependence on the energy level, and contacts 30 are operated by the reset relay to reset the circuit. The time out circuit may be caused to operate either by a single narrow frequency band sustained high level overload, which stops the sweep altogether, or a wide band lower level overload which reduces the sweep rate for such a duration as to allow the timer to operate.

Patent ES-367542-A1 (ES)
Title: High voltage switching device
IPC: H01H9/00
Filed: 1969-05-22
Abstract: Fixed contacts of a high voltage switch such as a transformer tap-changer are provided with means whereby they approach a spherical shape when not in use thereby enabling the dimensions of the switch to be reduced. A contact bar 1 mounted on an insulating support 12 has a dish-shaped screen 2 as shown and the space between the " dish " and contact bar 1 is covered by an annular domed member 3 urged outwardly by a spring 6, a circular plate 7 acting as a stop. When a pivoted contact (4, Figs. 2 and 3, not shown) comprising two spring- loaded arms (4a and 4b, Fig. 4, not shown) is moved into engagement with the fixed contact it depresses the member 3 so that the arms (4a, 4b) can embrace the bar 1 (Figs. 3 and 4, not shown) and as the contact is broken the spring 6 restores the generally hemi-spherical shape of the fixed contact. A screen 13 similar to screen 2 protects the terminal end of the fixed contact.
Patent ES-372588-A1 (ES)
Title: Registering apparatus
IPC: G06C15/02
Filed: 1969-10-06
Abstract: An electro-mechanical register in which numerical information is fed manually or automatically from say a punched tape or a computer, comprises a keyboard, Fig. 18 (not shown), which operates a combination of switches (1, 2, 4, 8) energizing a corresponding number of solenoids which determine the angular rotation in turn of a set of gears acting as a store, which rotation is transferred to print wheels for parallel visual read out. Energization of one or more solenoids 1, 2 &c., Fig. 17, on partial depression of any key moves a corresponding number of stops, e.g. 172, out of the path of sidewardly movable pins 152 of a friction driven paddle wheel 151 which advances a corresponding number of pins when a " go " solenoid 209 is energized on full depression of a key. On release of the solenoid(s) the pins are returned to the inoperative, i.e., left-hand position. Paddle wheel movement is transmitted through gears to an input gear 105 meshing in turn with each of storage gears 37 which are held from rotation in other than the meshing position by a spline on elements 106, 107. Depression of a print key (500) energizes a solenoid (66) which moves the gears into engagement with racks 13, Fig. 1, and also a solenoid (66A) which engages a machine clutch causing a forward, i.e., left-hand movement of the racks which each advance to a position corresponding to the remainder of the travel of the gears 37 to the zero position and hence print wheels 12 are also rotated correspondingly. Solenoids (66, 66A) are held energized for half a machine cycle by a cam-operated switch (560). The printing mechanism may be of known type and on completion of the left-hand movement of racks 13, a paper tape is brought against the type wheels. Subsequently the wheels are restored in zero position on spring return of the racks to their home position. Information may be entered through a remote keyboard or a local or remote punched tape, and machines may be run in parallel. Electrical signals from the switches may be transmitted to a computer also the printer may be controlled from such computer.

IPC: H02M7/757
Filed: 1971-08-17
Abstract: In a device for the control of line-commutated converters, the fundamental of the line voltage vector is filtered out by a vector phase filter and is shifted back in phase by an angle corresponding to the desired firing delay angle by a vector rotator as a function of a DC control voltage. The output of the vector rotator then exercises control via an angle switch which determines the trigger pulses of the converter valves at definite, recurring angular positions of the vector quantity fed to it. The control is independent of the wave shape and the frequency of the system.

Patent ES-433718-A1 (ES)
Title: Water-cooled flexible riser tube cable terminal
IPC: H01B7/42
Filed: 1975-01-10
Abstract: This water-cooled electric arc furnace cable terminal consists of a cup-shaped head and a rearwardly-projecting bar-shaped terminal blade containing a cooling water passageway communicating with the interior of the head and opening into a stepped riser tube surrounded by an annular cavity in which are secured, as by solder, the outer ends of the stranded cable conductors or "ropes." A perforated flexible tubular elastomeric core separates the inner sides of the stranded cable conductor from the inner component of the composite riser tube in spaced relationship therewith so as to provide a cooling water passegeway therebetween. The tubular core is provided with perforations enabling the cooling water to pass therethrough into the interstices between the hair-like wires of the so-called cable conductors or "ropes." To prevent clogging of the terminal by splinters of the hair-like wires of which these cable ropes are composed, the riser tube of the terminal is composed of coaxial outer and inner components of different diameters separated from one another by circumferentially-separated spacers so that the cooling water can flow through the arcuate auxiliary ports thus provided between the spacers and thereby flow around the outside of the inner component of the riser tube, as well as through the interior thereof, and thus bypass wire splinter masses which might otherwise clog or plug up the water cooling passageways and cause the cable to "explode" from the pressure of the steam thus produced.
