Patent ES-443570-A1 (ES)
Title: Address extending control unit
IPC: G06F12/02
Filed: 1975-12-17
Abstract: An address extending control circuit is disclosed which is provided with a memory having a memory capacity larger than that assignable with the content of an address register. The memory area of the memory is divided into a common block and a plurality of segment blocks of variable capacity. In a certain processing, the common block and any one of the segment blocks are utilized in pairs, thereby to obtain an extended address. To this end, an address extending address register capable of selecting a predetermined segment block of the memory is provided in addition to the address register. When the value in the address register is detected to be larger than a predetermined value, the content of the address extending address register corresponding thereto is appended to the content of the address register to increase the number of bits and a combination of the common block with one segment block of the memory is selected, with which an address in the selected segment block is accessed. Thus, address extending can be achieved with a simple construction.

Patent ES-462885-A1 (ES)
Title: Method of and system for operating an induction motor
IPC: H02P21/08
Filed: 1977-10-04
Abstract: An induction motor of the squirrel-cage type is driven from a polyphase power line through the intermediary of two cascaded thyristor arrays converting the line current into an adjustable rectified current and reconverting the latter into a stator current of variable frequency. The magnitude of the rectified current is varied via the first thyristor array, under the control of a tachometric signal from a speed sensor coupled with the rotor of the machine, to maintain the rotor speed at a selected level within a predetermined dynamic range in which the stator current varies approximately in proportion to the slip frequency under changing load. The slip frequency is adjusted by the second thyristor array under the control of an arithmetic unit which receives the tachometric signal along with a voltage feedback from the stator input and which maintains the stator voltage substantially proportional to rotor speed in order to stabilize the excitation current of the motor. The maximum value of the tachometric signal fed to the arithmetic unit is limited by a clamping circuit to allow the selection of rotor speeds above the dynamic range without further increases in power.
