Patent ES-373645-A1 (ES)
Title: Improvements in or relating to data-processing systems
IPC: H04M3/00
Filed: 1969-11-18
Abstract: Processing of call connection data in a telephone exchange system involves control circuits S1 to Sm and circuits such as allotters U1, U2, transfer of data between a control unit and an allotter being effected in response to a demand from the allotter by way of a circuit individual demand wire in a cable uz, demands existing in the cable uz being detected by a scanner distributor Z1 which gives access to a data bus system US, SU for the data transfer. Once a bus is seized for a demand the identity of the calling unit and/or the wanted unit is sent over the bus to engage the service of the control unit. If such a data transfer is required at the instance of a control unit S1 to Sn, a demand is made direct to the wanted allotter over an individual wire of the cable Sm. The allotters contain scanners whereby the demand is detected along with the identity of the calling control unit and the allotter can seize the data bus as described above. Markers M1 to Mm similarly gain access to a bus system MS, SM over demand wires mz supervised by a distributer Z2, or in response to a demand over cable Su, to exchange data with a control unit. Demand wire cables mz1 and uz1 allow the bus systems US, SU, and MS, SM, to exchange roles from time-to-time so that the allotters and markers are alternately served by one and the other bus. If one bus system fails the other bus system can serve both allotters and markers. The bus systems have separate GO and RETURN loops connected from send to receive circuits in the distributers Z1 and Z2. Allotters and markers are coupled by transformers in shunt across each transmission pair while control units are coupled to transformer windings in each leg of each pair, Fig. 2, not shown. Processing of a particular connection involves a series of data transfers over the bus system each transaction being interleaved with similar transactions conducted on behalf of other connections.

Title: Method and apparatus for inflating fluid passageways in metal strip
IPC: B21C37/14
Filed: 1971-03-12
Abstract: A method and apparatus for inflating lengths of metal strip having at least one inflatable fluid passageway, and preferably, long lengths of such strip. The process employs a coil of the metal strip. The metal strip preferably is of a composite metal, wherein the inflatable fluid passageways correspond to patterns of weld inhibiting material. The strip is paid off from the coil and pinched to prevent subsequent inflation from reaching the coil itself. The other end of the strip is clamped in a suitable inflation device through which pressure is applied to inflate the fluid passageway or passageways. The inflation proceeds up to the pinched off portion of the strip. Thereafter, the strip is severed just ahead of the pinching means, yielding a long length of strip having at least one inflated passageway while leaving an open tube in the end of the coil ahead of the pinching means for insertion in the inflation fixture for inflation of a subsequent length of strip. The apparatus comprises means for holding a coil of the strip, pinching means receiving the strip from the coil, inflation means receiving the strip from the pinching means and severing means spaced between the pinching means and the inflation means for severing the strip from the coil after it has been inflated.

Title: Industrial technique
IPC: F28F9/22
Filed: 1973-04-06
Abstract: An illustrative embodiment of the invention shows an heat exchanger for converting the secondary coolant feedwater in a nuclear power reactor system into superheated steam. The tube sheet adjacent to the feedwater inlet nozzle is protected from thermal shock by discharging the feedwater directly into the economizer and establishing a controlled secondary coolant flow or leakage from the economizer along the terminal portion of the tube bundle to the tube sheet. The heat absorbed in the secondary coolant flowing toward the tube sheet raises the coolant temperature and protects the sheet from thermal shock. The secondary coolant that collects between the economizer and the adjacent tube sheet, moreover, can be reintroduced to the tube bundle or bled from the secondary coolant loop.

Title: Method of making a hectographic master
IPC: B41M5/26
Filed: 1973-04-11
Abstract: A master for hectographic printing is made by advancing a paper sheet or tape having an obverse and reverse side in incremental steps past an operating station. At the same time, a carrier web having a thermo-melting color layer is similarly moved past the operating station at which latter is brought into contact with the reverse side of the paper, whose obverse side is sensitized so as to change color when subjected to heat. The obverse side is thereupon contacted at the station with heated instrumentalities which produce local color changes in form of indicia, and the heat passing through the paper causes corresponding local portions of the color layer to melt and adhere to the reverse side of the paper which faces the carrier web, thus producing on this side of the paper mirror-reversed replicas of the indicia, which replicas can subsequently be used for hectographic printing.

Title: Selective peach pitter
IPC: A23N4/04
Filed: 1977-07-16
Abstract: A torque-type pitter for pitting drupes such as cling-stone peaches and the like, having coplanar, body-bisecting and pit-holding blades, and coaxial elements for gripping the peach body at opposite sides of the plane of said blades for twisting the peach halves from the blade-held pit. One of said blades has pitting knives or a pitting spoon in the plane of said blade that are normally inoperative where the pit in the peach between the blades is sound, or momentarily appears to be sound, but upon said blade passing between the halves of a split pit without hesitation, said knives or spoon will automatically be projected into the gripped halves to positions in which the rotation of said halves by said elements will spoon-pit the halves. Where a pit is momentarily engaged by the pair of pit-holding blades as though it were sound and then the blades travel past the edges of the defective (or "late" split) pit, the pitting knives will remain in inoperative in the plane of the blade, thereby precluding mutilation of the halves as would occur were the knives to engage the pit or to cut remote from the pit during rotation of the bisected halves.
