Patent ES-353497-A1 (ES)
Title: Improvements in or relating to the regulation of electron guns
IPC: G05F1/52
Filed: 1968-05-03
Abstract: An electron beam furnace is provided with a regulated power supply which includes a protective circuit responsive to arcing in the furnace as evidenced by a rapid rise in operating current to a trigger level, the protective circuit operating firstly to reduce the current to a level sufficient to starve the arc within a period of time which is preferably within 15 milliseconds from the time the current reaches the trigger level and subsequently automatically to restore the current. As shown, an electron beam furnace 14 is supplied from a D.C. source 28 by way of a resistor 46, a series valve 16 and a transductor 122. The normal operating current, as sensed by the transductor 122, is maintained at a desired value by a control system 26 which operates in known manner to regulate the heating current supplied to the filament of the electron gun 12. The operating voltage is maintained constant by controlling the bias applied to the grid 20 of the valve 16 in dependence upon an error signal derived from a control circuit including a voltage sensing network 18, an isolating transformer 94 associated with converters 90, 98, a voltage regulator 102 which may be of the series transistor type, and a normally closed switching circuit 22. Thus in normal operating conditions both the voltage and current supplied to the furnace are controlled at desired values, but when arcing occurs the operating current rises rapidly this condition is detected by a sensor 24 which is connected across the series resistor 46 and which produces one output for application to the switching circuit 22 and another output for application to a restart circuit 114. When the rising current reaches a predetermined trigger level the switching circuit 22 opens to render the valve 16 much less conductive, whereby, within 15 milliseconds, the current is reduced to a level sufficient to starve the arc subsequently, and after a predetermined period, e.g. less than 10 milliseconds, a signal from the restart circuit 114 closes the switching circuit 22 and the operating current is restored. Should the arc still persist the switching circuit 22 is again opened and the cycle repeats until the arc is extinguished. Suitable arrangements, including transistors and thyristors, for the circuits 22, 24 and 114 are described with reference to Fig. 2 (not shown).

Patent ES-371622-A1 (ES)
Title: Method and apparatus for packaging a plurality of articles in predetermined arrangement
IPC: B65B35/58
Filed: 1969-09-17
Abstract: Cans 10, frictionally-retained in a plastics carrier 16 by the upturned lip 24 of each canreceiving aperture in the carrier, are each individually rotated in the carrier until its respective label or other identifying mark faces outwardly. Groups of cans assembled in their respective carrier are advanced by a continuously-driven conveyer 30 (Fig. 8) to a clamping station 40 whereat a pair of opposed pivotable and reciprocable clamps 44, 46 (Fig. 1) engage the first of the succession of can packs and transfer the first can pack to a working station 42 at which the individual cans are rotated to the desired orientation. The clamps are guided on longitudinal rails 36, 38 and are each reciprocatably driven by a cam and crank disc 56, 58 through a slotted crank 86, 88 and connecting rod 98, 100 so that, after the clamps engage the first of the can packs, the clamps are accelerated to separate the first pack from the successive packs. During this movement, enlarged cam segments 132, 134 on the crank discs acting through cam rollers 136, 138, 148, 150, Fig. 5 (not shown), on cam surfaces hold the clamps in engagement with the cans. On reaching the working station 42, the cam segments are no longer effective and a spring 126 pivots the clamps laterally away from the cans and holds them in this position whilst they are reciprocated back to the clamping station for engagement with the next can pack. At the working station, the top of each can is simultaneously raised into frictional engagement with a respective one of a plurality of continuously driven rotating pads 164 (Fig. 2) by a respective one of a plurality of heads 166, which are carried on a lifting frame 174. The frame is raised by cam and cam follower linkage 176, 178, 180, 184, Fig. 3 (not shown), so that each head urges each can upwards into driving engagement with its respective pad. Each head is rotatably mounted on a spindle 170 which is supported in a spring- loaded cup 192. Each cup is slidably mounted in a sleeve 172 and is held in an extended position therein by a latch plate 202. On engagement of the cans with the pads 164, the cans are rotated in the carrier until a photo-cell 216 associated with each can is actuated by a label or mark on the can when the can reaches its desired orientation and energizes a solenoid plunger 214 (Fig. 2) to release the latch plate so that the respective cup and head are urged downwardly by the cup spring 200 thus lowering and declutching the respective can from its drive pad. When all the cans of the pack have been thus orientated, the lifting frame is lowered, this movement automatically raising the cup against the cup spring to its extended position and resetting the latch plate to hold the cup in the extended position. The next pack is moved into the working station and pushes the processed pack on to a discharge conveyer 34.

Patent ES-430920-A1 (ES)
Title: Method and apparatus for cold-drawing metallic tubes
IPC: B21C1/24
Filed: 1974-10-11
Abstract: Steel tubes are cold-drawn in a bench wherein the reducing die is located in front of a sleeve defining with the external surface of the tube to be cold-drawn an elongated tubular confining space which tapers toward the die at an angle of less than 3 DEG . The space is filled with a lubricant at an elevated pressure of up to 100 atmospheres superatmospheric pressure, and such pressure rises automatically to a value exceeding at least 10 times the initial pressure when the tube is moved lengthwise at a speed of up to and in excess of 300 meters per minute. The rise in pressure of confined lubricant is due in part to friction between the lubricant and the external surface of the tube and suffices to insure that the moving tube remains out of mechanical contact with the die. A similar forwardly tapering confining space for reception of a pressurized lubricant can be provided between the internal surface of the tube and a confining member which is connected to and located behind a floating mandrel. The thus treated tube can be subjected to one or more additional cold-drawing treatments to reduce its outer diameter from 8-35 millimeters to about 3 millimeters and its wall thickness from about 3.5 millimeters to about 1 millimeter.

Patent ES-443923-A1 (ES)
Title: Switching and activity compression between telephone lines and digital communication channels
IPC: H04B7/212
Filed: 1975-12-29
Abstract: Digital exchange stations linked by earth satellite operate in a coordinately controllable time division switching and communication network system relative to externally attached telephone and data trunks. Modular switching equipment operating in coordination with satellite frames establishes and releases connection paths to trunk stores which interface with time and space domain channels of the system. Circuits through the system utilizing these paths are termed virtual connections because in different frames a circuit may be completed through different channels or even blocked under certain conditions. Telephone speech is converted between analog and digital forms relative to modular groups of 96 ports. Digital switching (slot interchange) equipment serving up to four groups (and cycling in coordination with satellite time division frames) cyclically completes local (intra-station) connections between ports and segments of toll (inter-station) connections between ports and locations in the trunk stores. The trunk stores comprise separate sections for system traffic bound to and from ports of the respective station. A duplicate arrangement of subsections in each section is alternately filled and emptied in successive frames enabling the station to maintain continuity of communication relative to the system in successive frames. The 192 bit spaces of each location are filled in one frame and emptied in the next frame. Groups of 96 outbound locations are "virtually" associated for transmission with groups of 48 time division transmission channels of said facilities. The association operates by a process of selection termed voice activity compression (abbreviated VAC) based upon activity information developed at the port interface and carried through the switching equipment in positional association with trunk locations. The VAC process assigns only locations (virtual channels) containing activity to up to 46 of the 48 time channels, eliminating any excess of active virtual channels (over 46) in a selective order of priority. VAC mask information transmitted in a separate one of the 48 time channels indicates the virtual-to-real (96-to-46) assignment for the respective group in the respective frame. A bit in the mask for each virtual channel of the group indicates the assignment or elimination of the respective virtual channel. Assigned channels are transmitted in the time order of respective mask bits. Establishment of virtual connections is restricted system-wide by tables stored in the stations. These tables are subject to external modification and may contain path exclusion information enabling the system to remain effectively operational with inoperative elements.
