Patent ES-357958-A1 (ES)
Title: Percussive electronic musical instrument with output level controlled by intensity of key depression
IPC: G10H1/057
Filed: 1968-09-09
Abstract: In a keyed electronic musical instrument comprising a plurality of tone generators each coupled to an output via an individual gate, each key being adapted to charge a capacitance to a voltage which increases with the strength of actuation of the key, and the capacitance voltage being fed to an actuating terminal of a gate for unblocking the gate to an extent which increases with the magnitude of the voltage, the difficulty arises that if the discharge time of each capacitance is short the tone decays too rapidly whilst if it is long the note cannot be repeated soon after a strong actuation. This is avoided by making the capacitance discharge rapidly at first and more slowly thereafter. In Fig. 2a the capacitance comprises two capacitors C1 and C2 in series each charged through a respective diode by voltage induced in associated coils S1 and S2 when the key moves the magnets M1 and M2. The initial discharge is mainly of C2 through R2 and takes 0À1-0À2 seconds the next stage of the discharge is of C1 through D3 and R1 and has a time constant of two to four times the initial value finally when the diode D3 cuts off, the discharge is through the load R and has an even longer time constant. In a modification (Fig. 3, not shown) the components S2, D2, C2 and R2 are omitted, and in another modification (Fig. 4a, not shown) the capacitor C2 is omitted in this latter case the resistance (R S ) in series with D2 should have a value of about five times the critical damping resistance of the circuit comprising the coils, the capacitor and the resistance.

Abstract: Ethylene and/or propylene are produced as follows: (a) a petroleum distillate boiling in the gas oil range and comprising aromatic, naphthenic and paraffinic components is treated to remove at least some of the aromatics (b) the treated feed is mixed with steam in a weight ratio of steam: hydrocarbon in the range 0À1- 2À0 (c) the feed is then cracked for 0À15-1À5 seconds to an outlet temperature of 1300- 1700 F. in a tubular reaction zone, the hydrocarbon partial pressure at the outlet being maintained at 6-20 p.s.i.a. and (d) rapidly cooling the effluent and recovering olefin product. Suitable feeds are light, heavy and vacuum gas oils and light and heavy catalytic cycle oils. The tubular furnace is suitably of the type having a convection-heated preheat section and a radiant-heated cracking section. The removal of aromatics in step (a) may be performed by solvent extraction or by solid adsorbents. Suitable solvents are furfural, SO 2 , phenol and dimethylformamide, and suitable solids are silica gel and molecular sieves. A dual column extraction is also referred to, in which the feed is contacted in the first column with an aromatics selective solvent, e.g. furfural-furfuryl alcoholwater mixture, aqueous DMF or aqueous tetrahydrofurfuryl alcohol, and the aromatic extract is then contacted in the second column with a displacer liquid, e.g. a naphtha-xylene mixture, which removes the extracted aromatics from the solvent.

Patent ES-439715-A1 (ES)
Title: Method of pan granulation
IPC: C05G5/12
Filed: 1975-07-24
Abstract: The invention provides an improved pan granulation process for the production of low-water or substantially anhydrous nitrogenous compounds. Hot nitrogenous melt and cooled particulate solids are fed to a rotating pan to form a cresent-shaped bed of rolling or tumbling particles, the thickness or depth of the bed increasing in the direction towards the periphery of the pan and its overflow sector, i.e. position 2 o'clock to position 6 o'clock when the pan surface is regarded as a clock face and the rotation of the pan is counter-clockwise. The cooled solid particles are fed to the pan at a point where the depth of existing material is small, desirably substantially zero, preferably in position 7 to 8 o'clock, if need be by feeding the particles through a tube or the like which extends into the tumbling material on the pan to the proximity of the surface of the pan itself. Subsequently, the cooled particles will then be covered by and with warmer particles tumbling over them. Further, the temperature of the product material as discharged from the pan is controlled to and maintained at about 4 DEG to 25 DEG C below the melting point of the material, and the main part of the melt is sprayed on to the surface of the bed within a zone in the quadrant 12 to 3 o'clock where the coarser particles appear, whereby the highest temperature of the bed will be restricted to a surface layer within this zone.

Title: Method and apparatus for monitoring the axial power distribution within the core of a nuclear reactor, exterior of the reactor
IPC: G21C17/108
Filed: 1977-03-04
Abstract: A method and apparatus for establishing the axial flux distribution of a reactor core from monitored responses obtained exterior of the reactor. The monitored responses obtained exterior of the reactor.

The axial height of the core is figuratively divided at a plurality of space coordinates sufficient to provide reconstruction in point representation of the relative flux shape along the core axis. The relative value of flux at each of the spaced coordinates is then established from a sum of the electrical outputs of the detectors, respectively, algebraically modified by a corresponding preestablished constant.

Title: Apparatus and method for conducting financial transactions
IPC: G07D11/00
Filed: 1977-12-12
Abstract: A currency dispensing apparatus employs a removable portable cartridge having a plurality of compartments for storing currency of differing denominations to be dispensed during successive transactions, another compartment for receiving a journal record printed as each transaction is completed, and a different compartment (preferably defined by a detachable portion of the cartridge) for storing rejected currency. Upon removal from the apparatus, the cartridge will thus contain all undispensed currency, including rejected currency, and also contain a complete journal record of all transactions conducted at the apparatus using that particular cartridge. The cartridge comprises two concentric members, the outer having an opening through which currency is dispensed, and the inner providing the compartments. The appropriate currency compartment is rotatably aligned with the dispensing opening, which is adjacent a dispensing station. The outer member is also rotatable independently of the inner member to change the position of the opening to enable detachment and later reinsertion of the different compartment. In a multiple dispensing station transaction terminal having three access stations 120 DEG apart, the outer member is rotatable to the respective stations so that all may be serviced by a single cartridge.

Title: A DC voltage converter
IPC: H02M3/338
Filed: 1979-10-25
Abstract: A self-oscillating D.C. voltage converter is proposed for supplying loads which can exhibit a short circuit and/or require a constant supply current. The circuit arrangement includes a transformer (N) with a primary winding (N1), a secondary winding (N3) for supplying a load and a secondary winding (N2) as a control winding. The primary winding is connected to a D.C. voltage source through a switching transistor (Q1) and a current measuring element (R3). An additional control transistor (Q2) is switched by the voltage drop at the current measuring element (R3) the control transistor acting on the switching operations of the switching transistor (Q1) in the same sense as the control winding (N2), limiting the peak current (I1) to a predetermined value, introducing the feedback operation and reducing the losses in the switching transistor (Q1) due to the enlargement of the flank slope on variation of the switched primary current (I1).
