Patent ES-347873-A1 (ES)
Title: Improvements in manufacture of printed circuit boards
IPC: C23C18/16
Filed: 1967-12-01
Abstract: A printed circuit having metallized holes is formed by coating exposed conductor lines on a catalytic base with a permanent insulating mask, forming holes through the mask and base and electrolessly depositing metal on the walls of the holes. In the embodiment of Fig. 10 conductors 14 are formed from a metal-clad catalytic base by a print and etch method and after removal of the etch resist 15 both sides of the base are coated with an insulating non-catalytic permanent mask 17. Holes 22 are then formed through the panel which is then subjected to an electroless plating bath to form deposit 24 on the hole walls. The insulating mask 17 may be deposited so as to leave exposed lands around the holes which are coated with metal during the subsequent electroless plating process, Fig. 12 (not shown). During the plating process the wall coating 24 grows vertically as well as horizontally over the insulating mask so that by choosing the appropriate thickness of the mask the wall coating may or may not creep to the surface of the mask to form eyelets, Figs. 13, 13A, 13B, 13C (not shown). The process shown in Fig. 10 may be extended to form multilayer circuit boards by interspersing catalytic bases in a stack of bases carrying circuit conductors, masking the exposed conductors and forming the metal-lined holes as described above, Fig. 12 (not shown). In the embodiment of Fig. 15, conductors 1202 are formed by a print and etch process on both sides of catalytic base 1000. Catalytic permanent insulating masks 1610 are then deposited over the conductors 1202 after which holes 1500 are provided and metal deposit 1501 formed by an electroless plating process. After superimposing removable insulating masks 2000 on the top and bottom surfaces of the board, the metal deposit 1501 on the hole walls is built up, 2200, by electroplating. Mask 2000 is finally stripped off. In a further embodiment, Fig. 16 (not shown), printed conductors on both sides of a catalytic base are coated with a catalytic insulating layer on which is superimposed a non-catalytic adhesive layer. Holes are formed and electrolessly plated as previously.

As the inserter passes into theshed it beats-up the previous weft and takes in the new weft. At the far side of the shed a member 50, on retraction of the inserter, clamps the new weft and pivots the guide 24 and clamp 27 so that the weft may pull through the inserter, as it retracts, to the Fig. 3 position.
Patent ES-361853-A1 (ES)
Title: Instruction retry apparatus including means for restoring the original contents of altered source operands
IPC: G06F11/14
Filed: 1968-12-26
Abstract: In a data processing system, operand words fetched from a storage field in a storage unit are stored in a plural-word addressable backup store and also processed to give a result which is stored back in the field, detection of an error in the system causing replacement of the result in the field with operand words from the backup store to permit retry of the processing operation. The storage unit is the main storage of the system, and the back-up store is addressed by the three lowest order bits (excluding the byte-selecting bits) of the main storage address, for storing a given operand word from main storage. Each word location of the back-up store has an associated "fetch" trigger set when the location is loaded, and an associated "store" " trigger set when the corresponding operand word is overlaid in main storage by a respective word of the result. Replacement of result words in the main storage by operand words from the back-up store on error detection only occurs if a source data change " trigger is set to indicate that overlaying by the result in main storage has occurred, and then only with respect to those words having their "store" triggers set. The "source data change " trigger is set on setting of any of the " store " triggers, or by a decoder fed from a microprogramme read-only store controlling the system. Retry of the processing operation is also preceded by loading of an instruction address register, programme status word register, and general purpose stats (storing machine conditions) from respective back-up registers (separate from the back-up store). An error counter causes branch to an error analysis sequence after a predetermined number of unsuccessful retries of a given instruction.

Patent ES-370292-A1 (ES)
Title: Capacitive networks
IPC: H01G4/38
Filed: 1969-08-06
Abstract: A capacitive network is derived from a parent capacitor consisting of two electrodes or two sets of electrodes, adjacent electrodes being separated by dielectric material and electrodes of opposite polarity being staggered so that they extend to opposite end faces of the capacitor, the network being obtained by making cuts each extending from an end face over at least the whole width of the overlapping zone, but not extending to the other end face. As shown cuts 3 and 5 are made from one end face, cut 4 from the other to give four series-connected capacitors between terminals a and b (see also Fig. 2, not shown) suitable for use as a voltage divider. By making all the cuts from one face a parallel arrangement of capacitors is obtained (Figs. 3, 4, not shown). Resistors, inductors and other components may be connected between the subsidiary capacitors to give more complex networks. In other embodiments (Figs. 5 to 8, not shown) T and # capacitor networks are obtained, or arrangements for use as suppressors (Figs. 9 to 12, not shown). The cuts may be filled with insulating material, e.g. by potting the component. The individual capacitor units formed by making the cuts may themselves comprise an arrangement of seriesconnected capacitors by removing strips of electrode material at right angles to the cuts (Fig. 13, not shown). Alternatively where the electrodes are formed by metallizing the dielectric, unmetallized strips may be left.

Title: Particulate metallurgical hot topping compositions and method of use
IPC: B22D7/10
Filed: 1971-11-11
Abstract: Preparation of particulate metallurgical hot topping compositions that react in situ to form a protective cover over the exposed surface of as-cast ingots. The compositions consist essentially of 9 to 33 percent by weight of oxidizing constituents, 40 to 65 percent by weight refractory constituents and 15 to 45 percent by weight of fuel constituent. Careful control of the quality and size of the major fuel constituent minimizes smoke evolution during reaction of the composition and subsequently if the covering is disturbed. By varying the ingredients in the hot topping composition, there can optionally be produced (1) a hard crust so that the as-cast ingots can be moved before a major portion of the ingot has solidified (2) a medium density crust for delayed addition of a highly exothermic hot topping composition, or (3) a low strength crust for "back-pouring" practice.
