Title: Toroidal winding structures
IPC: H01F30/16
Filed: 1966-12-20
Abstract: An inductive device, e.g. a transductor, comprises a plurality of toroidal core sections 13-17 spaced by members 20-23 extending outside the core to restrain the outer limbs of preformed U-shaped conductors 34 straddling the core and joined to form the winding. Spirally wound or transverse laminated core sections are bolted together with insulating boards 20- 25 and insulated copper conductors threaded through holes in the boards outside the core. An insulating tube 32 is forced within the core to wedge the inner limbs of the conductors against the boards and the assembly located via spacers (33), Fig. 2 (not shown), over a hollow conductor 12 whose inductive impedance is to be controlled. The conductors are brazed together to form a control (36) and bias winding (37), each consisting of two parallel-connected sections, to vary the core saturation. Alternatively, the conductors may be connected in parallel, or in parallel-connected pairs connected in series.
Patent ES-336611-A1 (ES)
Title: Control system for universal motors
IPC: H02P7/295
Filed: 1967-02-09
Abstract: A capacitor C 1 is charged from A.C. terminal b at a rate determined by the adjustment of variable resistor R 2 , which is shunted by fixed resistor R 1 , until Zener diode D 2 breaks down to trigger thyristor T in series with motor M. During the opposite half-cycles of the source a, b, the resistor R 1 only is connected in series with the capacitor C 1 , due to the blocking effect of diode D 1 , and the capacitor is partially discharged. The voltage across capacitor C 2 increases with the motor-current to reduce the discharge rate of the capacitor C 1 , thus decreasing the duration of the next charging period before the diode D 2 breaks down. An increase in motor current thereby advances the instant of ignition of the thyristor T, whereas the ignition-point is delayed if the motor is unloaded. The motor may be connected to a filter network to suppress transients due to switching of the thyristor T which is adapted to be shortcircuited for full-power operation. The diode D 2 may be omitted.

IPC: G01L7/16
Filed: 1967-03-14
Abstract: A pressure sensing system comprises sensing means responding to a pressure downstream of a filter below a certain value and a pressure drop across the filter above a certain value by operating indicating means. Oil is pumped into housing 1 from duct 2 and passes through filter cartridge 4 to exit by ducts 5, 6. Pistons 10, 11 are positioned in a bore 8 of the housing and are joined together and to the housing by pins 16, 13. An electric circuit with a lamp 29 is connected to housing 1 and pin 13. Before operation of the pump, spring 12 holds contact ring 19 on piston 10 and abutment 20 of pin 13, and lamp 29 lights. When the pump starts the downstream pressure acts to move both pistons together, piston 10 moving ring 19 out of contact with pin 13 against the bias of spring 12 and light 29 goes out. Pins 16 and 13 come into contact. On blocking of the filter, a pressure difference forms across piston 11 and moves it against the bias of spring 14 until contact 23 closes on contact 24 and lamp 29 again lights. Bypass valve 7 opens at a greater pressure difference.

Patent ES-352482-A1 (ES)
Title: Circuit arrangement for imitating the touch of musical instruments with percussion
IPC: G10H1/055
Filed: 1968-04-06
Abstract: A circuit for imitating the touch of a percussive musical instrument is arranged so that the build-up time of the note from a tone generator is kept substantially constant or made to vary less than does the duration of actuation of the key 1 resulting from variation in touch intensity. The key is mechanically coupled to a magnet 2 such that actuation of the key will cause flux lines from the magnet to cut an inductance L so inducing a voltage therein which is fed through a diode D to a capacitor C. In accordance with this invention diode D is biased by a battery B such that it will only conduct when the voltage induced across L is greater than the battery voltage. Biasing of the diode D reduces the ratio between the build-up times for the softest and loudest touches on the key. A resistor R is used to reduce the ratio of the capcitor voltages for the loudest and softest touch so that they more nearly equal the ratio of the intensity of actuation for the loudest and softest touch. Fig. 3 (not shown), illustrates the further modification of placing an element X in the circuit between resistor R and diode D to compensate for the diode in the initial part of its characteristic if the voltage induced in the coil for the softest touch (the least touch to produce an audible note) only just exceeds the battery voltage. Element X is such that its resistance increases with increasing current in the initial part of the forward characteristic of the diode, for example a tunnel diode. Fig. 5 (not shown), illustrates a method of reducing still further the ratio of the capacitor voltages for the loudest and softest touch by connecting a further diode, reverse biased by a voltage E 2 , in parallel with inductance L, the effects of which are shown in Fig. 6 (not shown). Two alternative methods of providing a voltage threshold for the diode D are described, one in which a diode with an inherent voltage threshold is used and one in which a battery in series with a resistor is connected in parallel with the diode.

Title: Spacer grid for nuclear reactor fuel element assembly
IPC: G21C3/34
Filed: 1969-07-01
Abstract: A spacer grid for a fuel element assembly comprises a lattice of interassembled sheet metal members 2, 4 which define compartments having a square section, each member 2, 4 being cut-out and comprising two parallel rectilinear ribbon elements 2a, 2b, 4a, 4b, narrow corrugated strips 12 forming a number of projections (e.g. 13, 14, 15) on each side of the member and defining openings 10 between the ribbon elements, and slits 18, 20 forming interruptions in one of the ribbon elements 2a, 4b in the centreline of each opening 10 so as to permit the insertion of the continuous ribbon element 2b, 4a of another sheet metal member. The sheet metal members 2, 4 are attached at their extremities to similar sheet metal members (Fig. 1, not shown) which form the sides of an outer frame. Each ribbon element 2a, 2b, 4a, 4b is provided, in line with the corrugated strips 12, with bosses 16 directed towards the same side as the projections 13, 15 but of greater height. Each compartment of the grid is limited on each of its four sides by a portion of a sheet metal member, the central part of which is formed by a corrugated strip 12, whilst the corners of each compartment are cut away since they are formed by the junction of the ribbon elements adjacent openings 10. Each fuel element will be in contact on the one hand with the projection 14 of a sheet metal member 2 and the bosses 16 of the adjacent member 2 and on the other hand with the projection 14 of a sheet metal member 4 and the bosses 16 of the adjacent member 4. The flexibility imparted to each corrugated strip 12 by the projections 13, 15 serves to absorb deformations while permitting the coolant to flow between the strip 12 and the fuel element. For the purpose of guiding control rods, guide tubes can be placed in some of the compartments and secured to the corners of these by means of radial fins. In a fuel element assembly, a number of the abovedescribed grids are secured to each other and to the top and bottom support plates of the assembly by means of spacer tubes, which serve also as passageways for the guide tubes.

Patent ES-372590-A1 (ES)
Title: Reciprocable platen in selective print wheel printing machine
IPC: G06K15/06
Filed: 1969-10-16
Abstract: A desk type peripheral equipment for use with a computer to feed in and receive out numerical information on which the computer will perform arithmetical calculations comprises a unit, Fig. 1 (not shown), having one set of keys 0-9 plus decimal point and a second set (202) for directing the information. Depression of any 0-9 key causes through a linkage a combination of switches to be operated which energize a corresponding number of electromagnets 301a-301c, thus releasing one or more gears 321a-321c which transfer a part of the rotation of a shaft 307 through the gears 306a-306d having numbers of teeth arranged in a binary progression, i.e. 1, 2, 4 &c. to a set of gears, e.g. 351a, each acting as a store and mounted on shaft 337. An interlock actuated either through a linkage or a captive ball arrangement prevents simultaneous depression of more than one key. When all digits of a number have been recorded, a function key, i.e. +, - is depressed, which causes the gears on shaft 337 to simultaneously engage and rotate through intermediate gears printing type characters 503 carried on another shaft 504. After rotation to the appropriate positions, the type characters are held temporarily by a spring-loaded locking bar and a resilient printing roller 534 is moved through an arc to press paper from a feed roll against an endless inking tape and the type characters. The arc of movement of the roller is limited so that the meeting face does not pass below the bottom of the type hence avoiding movement of the paper and consequent smudging. As the print line is two spaces below an observation window (512), Fig. 1 (not shown), in the unit, a mechanism is included to advance the paper a corresponding amount after each printing operation, and to retract it one space before the next printing operation. The unit may be operated so that information may be received concurrently with the printing operation. A register may be employed to develop binary signals in serial form for feeding into a computer and also receive information from the computer in serial form and convert it into parallel signals to operate the printing mechanism. The unit may be constructed with internal electronic computing and data processing circuits to form a complete unit but such circuits do not form part of the invention.

Title: Process for making sodium perborate tetrahydrate
IPC: C01B15/12
Filed: 1971-01-23
Abstract: Sodium perborate tetrahydrate is made by reacting, in solution, metaborate with hydrogen peroxide. Up to the time when crystallization sets in the reaction partners being used in a stoichiometric amount or hydrogen peroxide being present in a barely stoichiometric amount or in a slight excess, the temperature of the reaction is maintained at at least 15 DEG C and the component solutions are employed in concentrations so as to provide for formation of 90-160 g per liter of starting solution of sodium perborate tetrahydrate. Once crystallization has started, the precipitation is continued with an excess of sodium metaborate and the mass is cooled so as to cause a temperature drop. After crystallization is complete, the precipitated sodium perborate is then separated out and dried.
