Patent ES-352491-A1 (ES)
Title: Magnetic storage arrangements
IPC: C22C29/08
Filed: 1968-04-06
Abstract: A non-destructive read-out two core per bit memory comprises a " waffle-iron " type baseplate superposed by a planar thin film of isotropic magnetic material. The base-plate of ferrite material is provided with slots 10, 11, digit wires 13, 14 and word lines 17, 18. The digit wires are arranged in pairs interleaved with each other, Fig. 1 (not shown), so that adjacent wires of each pair are spaced from each other by a wire of another pair in order to suppress noise during a read operation. Each bit comprises two storage areas 22, 23 in the overlying thin film, the magnetic circuit of each storage location being completed by the adjacent posts 12 of the base plate. In a read/ write cycle a positive clear pulse is applied over wire 17 in a direction such that both areas 22, 23 are set to the condition -#. This pulse in wire 17 is followed by a negative half-write pulse in this wire coincidently with another negative half-write pulse on digit wire 14 via switch 20, this resulting in the magnetization of area 23 being switched to the condition # whilst that of area 22 remains in its original condition representing a stored " 0 ". Information is then read out non-destructively by applying a negative half-write pulse to word line 17 which tries to switch area 22 to the # condition inducing an output in wire 13, the magnetic condition of area 23 being unaffected by the read pulse. The polarity of the output signal difference of wires 13, 14 is sensed by amplifier 21. At the end of the read pulse the condition of area 22 reverts to its original state -#. If a "1" is written into the storage location a clear pulse is again applied to word line 17 followed by coincident half-write pulses on lines 17 and 13 switching area 22 to the # condition. Read out is non-destructively performed by again applying a half-write pulse to the word line.

Patent ES-357057-A1 (ES)
Title: Method and apparatus for control of high speed elevator
IPC: B66B1/16
Filed: 1968-08-08
Abstract: In a control system for a high speed lift, a register SE indicates the next floor at which the lift would be able to stop the value on this register is compared with a value representing the actual position of the lift and from the difference a value V m is continuously generated which represents the maximum speed at which the lift may be travelling in order that it stop at the indicated floor the value V m is compared with the actual speed V i of the lift and when these are equal a calls monitor 39 determines whether there is a call to the indicated floor, in which case an automatic speed control system causes the speed of the lift to decrease according to the value V m , or not, in which case the lift continues and the register SE is advanced to indicate the next floor. The automatic speed control system is employed to cause the lift to follow a predetermined acceleration low diving starting and to maintain a constant running speed. The lift cage CA is driven by a winch motor SM which also drives a tachogenerator T producing the speed signal V i and a pulse generator disc DP which in conjunction with counter 55 produces a signal [alpha] representing the position of the lift. The counter 55 is supplied with pulses Q through a divide by 8 circuit 57 the pulses are also applied direct to a second counter 56 but this is normally held off by a gate 59. When the difference approaches zero a control circuit 58 opens gate 59 to start counter 56 and closes a gate 60 to stop counter 55. The signals a and are therefore fixed but a new signal [alpha]1 is generated. The two signals [alpha]1, 6 are applied to a function generator 37 which produces the value V m , the signal [alpha]1 providing a more precise value V m as the lift comes to a halt. The lift CA carries sensors DB, DH co-operating with overlapping magnetic plates H1, B1 to generate signals H, B indicating the proximity of the lift to floor level N. When both signals H, B are being generated, i.e. the lift is exactly at the floor N, a signal is applied from a floor generator ME to correct the counter 55 for errors due to slip, &c. at the winch. The Specification describes in detail a binary logic system employing all NOR gates which may employ either semi-conductors or electromagnetic relays Figs. 5-13 (not shown) and also briefly an analogue system performing the same operations Figs. 14- 19 (not shown).
Patent ES-359679-A1 (ES)
Title: Driven inverter dead-time circuit
IPC: H02M7/537
Filed: 1968-10-19
Abstract: In an inverter, wherein square wave drive signals from a source 16 cause pairs of transistors 12, 13 and 14, 15 to conduct alternately to supply a load 11 with A.C. from a D.C. source 10, the drive signals are shorted by a transistor 27 during commutation period to ensure a definite "dead time " so that one pair is completely turned off before the other pair is turned on. The drive signals are applied to the transistor's bases by respective secondaries 18-2, 18-3, 19-2, 19-3 of drive transformers 18, 19. The drive signal current B (Fig. 2) is monitored by a primary winding 21-1 in series with the primaries 18-1, 19-1 of the drive transformers and with a saturable reactor circuit 20 so that when the drive current changes direction a voltage is induced in secondary 21-2. This voltage is rectified in a bridge 24 and causes a current pulse C to flow through a capacitor 26 to T27 base saturating the transistor which acts as a short-circuit across auxiliary windings 18-4, 19-4 of the drive transformer via rectifier bridges 32, 33. Thereby the drive signals are effectively shorted. A diode 28 allows C26 to discharge between the pulses. Because of phase difference between drive voltage A (Fig. 2) and drive current B, due to the saturable reactor circuit, voltage wave polarity changes distort the current wave as indicated and can cause ringing currents which may undesirably initiate shorting pulses. This is prevented by a blanking signal D which back biases T27 and is produced by a transformer 22 the primary 22-1 of which senses each time the voltage wave polarity changes and induces a voltage in secondary 22-2. This voltage is rectified at 30 and applied across the base and emitter of T27 preventing its conduction.
