Patent ES-372080-A1 (ES)
Title: Digital commaless code remote control system
IPC: G08C19/28
Filed: 1969-10-02
Abstract: In a remote control system the receiver responds to a repeatedly transmitted phase unique binary coded signal, i.e. a signal coded so that the sequence of bits sent when a word is repeated does not contain a sequence representative of any other word in the code, and includes a decoder for recovering the coded bits from the transmitted signal, a shift register into which the bits are loaded serially, a fast shift device for cycling the bits through the register each time a new bit is loaded and a number of decoders each responsive to a particular combination of bits stored in the shift register. Transmitter.-The commands are set up on a keyboard carried by an operator, encoded by a diode matrix and repeatedly transmitted over an F.M. radio link to the receiver. The transmitter is arranged to repeatedly transmit a group of coded signals, each group comprising the coded signal and at least one repeat thereof, at pseudo-random intervals under the control of two multivibrators as long as the input remains the same. When the input is changed the transmission in progress is interrupted and a new transmission started. A deadman's control shuts down the transmitter if the keyboard is tilted more than a predetermined amount. Receiver.-The decoded signal is loaded into a shift register 33 on mark and space leads under the control of clock pulses applied to gates 29 and 30 by a control 28. As each bit is loaded the contents of the register are cycled once via the recirculating loops 31, 32 under the control of high speed shift pulses from the control. Thus the decoder which consists of a diode matrix connected to respective stages of the shift register and enabled by the high speed shift pulses, is given the opportunity of recording any valid code pattern which may appear. If the decoder recognizes a valid code pattern, one line to the temporary store 40 is energized and the corresponding store location is energized when it is enabled by a pulse from a counter 35 which performs a parity check on the cycling signals in the shift register. The " OR " unit 42 then generates a signal indicating that a valid command has been recognized, this signal being gated with the parity pulse and with a pulse indicating that the correct number of shifts have been made in the register 33 to enable the command to be read into the store 41. The store 40 is cleared by the pulse which enables the store 41 after a delay by the delay circuit 38. One of the relay drivers 44 is therefore selected and the command is effected. A check unit 45 checks that the store 40 has been cleared within the allowed time and that the store 41 has also been cleared within a predetermined larger period of time. If the unit detects that these clearances have not occurred correctly, the receiver is shut down. The unit 45 also shuts the receiver down if no commands have been received for six seconds and a particular command has to be sent to reactivate the system.
Patent ES-378752-A1 (ES)
Title: Electronically controlled fuel-supply system for compression-ignition engine
IPC: F02M51/00
Filed: 1970-04-17
Abstract: One or more cylinders of a compression-ignition engine are connected to respective supply conduits through control valves normally spring-biased into a closed position. A feed pump periodically delivers fuel under pressure, from a reservoir, to a distributing channel leading to the supply conduit or conduits, this channel also having a return conduit for each cylinder with a bypass valve closed during all or part of the compression stroke of the pump. The closure of this bypass valve, during a gating interval established by an electronic network, causes a pressure buildup in the supply conduit sufficient to open the control valve against the force of its loading spring so that fuel under pressure enters the injector throughout the gating interval whose timing and duration may be determined by one or more operating parameters, such as throttle position and engine speed, fed into the network.
Patent ES-384061-A1 (ES)
Title: Frame synchronization system
IPC: H04J3/06
Filed: 1970-09-29
Abstract: An incoming TDM bit stream, containing synchronization signals in one or more time positions of each TDM frame is monitored by a first circuit to test the stream synchronization signal versus local synchronization signal. While this is in progress a second circuit looks for the stream synchronization signal in bit stream. If the first circuit shows that synchronization is O.K., then there is no change. However, if the first circuit shows that synchronization is lost, then the synchronization signal detected by the second circuit is used as a new local synchronization signal. The concurrent operation of the first and second circuit enables rapid resynchronization when synchronization is lost.

Title: Balanced tiltable, rotating mirror with its optical axis angularly offset from its axis of rotation
IPC: G01S3/78
Filed: 1970-11-18
Abstract: The mirror, such as a mangin-mirror, is useful in a system which automatically detects a deviation between a target and an object moving towards the target by comparing the line of sight to the target and the line of sight to the object. The mirror has a first axis about which it rotates and an optical axis which is displaced at an angle from the rotational axis. The rotational axis is kept coaxial with the target line of sight. The mirror is selectively tiltable to one of two discrete positions about its optical axis so that, as the mirror rotates, the reflection from the object forms two images, corresponding to the two mirror positions which conically scan a detector plane. Two pairs of right-angled light detectors, one for each position, are located on the plane. By comparing the time intervals for each pair of detectors when the reflection crosses the detectors, the deviation can be calculated, and by other equipment corrections in the path of the object can be made.

Patent ES-413092-A1 (ES)
Title: Electronic system to control operator circuits as a function of speed of machine rotating member
IPC: F02P9/00
Filed: 1973-03-28
Abstract: An electronic engine r.p.m. limiter for use with an electronic ignition system controlled by a magnetic pulser generating pulses having a frequency proportional to the engine speed. An amplifier-waveshaper at the input of the limiter device supplies a control signal both to the electronic ignition circuit and to the remainder of the limiter device. This remainder converts the incoming pulse signals to a D.C. signal varying in accordance with the engine speed and compares this variable D.C. signal with a fixed D.C. (threshold) signal. When the variable D.C. signal exceeds the fixed threshold, an actuator circuit becomes operative to short-circuit the control signals for the electronic ignition, thereby cutting off the operation thereof until the engine speed is below a predetermined maximum limit.
Patent ES-420582-A1 (ES)
Title: Hydrometallurgical leaching
IPC: C22B3/02
Filed: 1973-11-08
Abstract: A process and apparatus for hydrometallurgical leaching of unseparated, crushed mineral ores using a vessel having liquid stream forming nozzles in the lower portion thereof which operate to direct a stream of leaching liquid into solids in the lower portion of the vessel and to create a highly agitated interaction zone above which solids are settling under gravity and through which liquid from the lower portion rises upwardly in counter-current flow. The vessel is sufficiently high that an overflow of low solids content liquid is taken from the top. Outlets, as for example discharge piping or sumps, are provided in the bottom of the vessel for the controlled removal of solids therefrom. In multistage operation, the solids content of the overflow liquid is removed and the liquid content of the underflow is removed and combined to yield a mineral pregnant liquor which serves as the leaching liquid for a preceding stage where less depleted solids are being processed. Solids removed from a stage are passed to a subsequent stage where less pregnant leaching solution is used, so that the solids not only are processed in each stage in counter-current flow to the leach solution, but the interstage progression of the solids and leaching liquid is also counter-current. Single stage continuous operation is also disclosed in which solids having passed downwardly through the reactor are discharged periodically through a discharge trap formed in the lower portion of the vessel so as to minimize the amount of liquid discharged with the solids.

Patent ES-445902-A1 (ES)
Title: Pneumatic vehicle jack
IPC: B66F3/24
Filed: 1976-03-09
Abstract: A pneumatic vehicle jack comprises a jack cylinder with a body and a piston rod assembly movable relative to each other, two levers pivoted to said body or piston rod assembly, located on either side of the longitudinal axis of the jack cylinder and carrying vehicle and ground engaging shoes, and two struts pivotally mounted between said levers on the one hand and said piston rod assembly or cylinder body on the other hand. A cartridge of compressed gas can be removably connected to said jack cylinder for actuating the same. Actuation of the jack cylinder causes the pivot points of the levers and struts to be brought closer together, to move the shoes away from each other. At the beginning stage of the actuation movement, the lever system comprising the levers and struts reduces the force exerted by the jack, and at the end of the said movement it increases said force. Because the volume occupied by the gas contained in the cartridge increases during the actuation of the jack, the force exerted by the jack cylinder progressively decreases. Thus, the lever system compensates for this decreasing force and a substantially constant force is exerted by the vehicle jack over its whole stroke, and the raising movement of the vehicle is also progressive and constant.
