Filed: 1969-10-20
Abstract: In a system for remote metering between at least one fixed interrogator-receiver station and at least one transponder, the transponder, Fig. 1a (not shown), transmits a pulse pair spaced by a time interval t representing the input analogue signal Ua, this pulse pair being preceded by a pulse pair spaced by a time interval to representing a reference voltage. The pulses are transmitted as bursts of low-frequency modulating a carrier wave. At the interrogatorreceiver, Fig. 2a, circuit 48 provides timing pulses from the received signal which control the operation of switches 29, 30, 34, 40, 46, switch 46 being an electromagnetic relay and the remainder being field-effect transistors. During the time interval to the switch 30 connects a D.C. source 28 to an integrator 32, 24, 26, the output of the integrator being supplied via switch 34 to a capacitor 38. The voltage across the capacitor 38 is compared in a differential amplifier 41 with the reference voltage supplied from a source 42. At the end of interval to switch 34 opens, switch 46 becomes conductive so that the output of the comparator is supplied via an inverter 43 and switch 46 to the input of the integrator and at the next integration during interval t compensates for any error arising in the transponder due to temperature variations &c. The output Ua is taken from across capacitor 36, which is charged via switch 34, at the end of period t. Switch 29 is closed momentarily at the end of each interval t 0 , t 1 , to discharge the capacitor 26. A plurality of transponders may be interrogated in accordance with a predetermined programme sequence, Fig. 4 (not shown).

Title: Separation of propylene oxide from water by distillation with ac-8 to 12 hydrocarbon
IPC: C07D301/32
Filed: 1970-04-03
Abstract: Propylene oxide is separated from water by (a) distilling a feed mixture of propylene oxide and water in the presence of a paraffin or cycloparaffin containing 8-12 carbon atoms and removing the major proportion of propylene oxide and paraffins as bottoms and the major proportion of water as overhead. Preferably the paraffin is present in an amount of 5-40 parts by weight per part of propylene oxide. Since the overhead contains some propylene oxide in addition to water the efficiency of the reflux may be enhanced by cooling the overhead to a temperature at which the maximum solubility of water in propylene oxide is exceeded and a separate water phase occurs. This water phase can be decanted and a portion of the enriched propylene oxide stream used as reflux. The amount of water in the reflux can also be reduced by injecting paraffin into the overhead. The bottoms can be subjected to further separation to remove the paraffin from the propylene oxide.

Patent ES-409420-A1 (ES)
Title: Data processing system
IPC: G06F7/74
Filed: 1972-12-07
Abstract: This case describes a find-first-one (FFO) instruction which is used to scan a table of 16-bit words which are successively addressed and loaded in an accumulator, the address being obtained by indexing the address of the first word with the contents of an index register which are successively increased by 1. Each time a word has been stored in the accumulator a find first one instruction FFO is executed. This instruction finds the leftmost 1-bit in this word, resets this bit in this word, and shifts the contents of the index register by four positions to the left. In this way the contents of the index register directly indicate the position of the leftmost 1-bit in the table.
Patent ES-413756-A1 (ES)
Title: Asynchronous time division multiplexer and demultiplexer
IPC: H04J3/07
Filed: 1973-04-16
Abstract: There is described an asynchronous multiplexer and demultiplexer that operates on the basis of a stuff only technique. The multiplexer includes a different elastic store for each of the asynchronous input PCM data groups. Each of the elastic stores include a buffer register whose writing clock is synchronous with the asynchronous group input bit rate clock and a read clock which is synchronous with the bit rate of a synchronous data format employed for multiplexing the asynchronous group inputs. Each of the elastic stores produce a stuff request signal when the phase difference of the read and write clocks is equal to a given period, in numbers of bit periods. A common stuff control circuit samples the stuff requests and provides a control signal to inhibit the read clock to add or stuff a single stuff bit to the associated group data for each stuff request. Timing signals generated from a reference oscillator define the synchronous data format which includes 64 midframes within a superframe with each of the midframes including 15 subframes. Odd numbered ones of the subframes include 9 data bits and even numbered ones of the subframes include 8 data bits. The 9th data bit of the odd numbered subframes provide an overhead channel for transmitting digital voice orderwire, digital data orderwire, control words, a "zero" short sync bit, a "one" short sync bit and a long sync bit in each midframe. The bit assigned to the control words are employed to identify at the demultiplexer where the stuff bit has been added to the data format. The demultiplexer includes timing signal generators driven by the superframe rate recovered from the received data signal to provide the necessary timing signals to identify the supergroup frame, the midframe, the subframes and the data bits within the subframes. The timing signal generator in the demultiplexer is synchronized to the timing signal generators defining the data format in the multiplexer by a superframe recovery circuit responsive to both a short sync code and a pseudo-random long sync code. A common destuffing control is provided responsive to the code word identifying the presence or absence of a stuff bit to destuff the identified group data and thereby return the stuffed multiplexed group data to asynchronous group data as originally applied to the elastic stores of the multiplexer. The demultiplex includes for each asynchronous group data a different elastic store wherein the write clock is controlled by the recovered supergroup bit rate and the read clock is controlled at the group or midframe rate provided by the timing signal generators. The destuff control from the common destuff control circuit controls the write counter to cause destuffing of the associated one of the stuffed group data. A heterodyne type phase locked loop is employed in conjunction with each of the elastic stores to remove jitter from the destuffed group data.
Patent ES-418979-A1 (ES)
Title: Switching circuit
IPC: H04N9/71
Filed: 1973-09-21
Abstract: A switching circuit in which the signal path between a signal input and a signal output terminal includes at least two amplifier stages, the first one of which has its collector connected in a series circuit with a load impedance and the emitter-collector circuit of a switching transistor. The switching transistor is switched between a conductive and a non-conductive state by a switching voltage applied to its base. The base of a second amplifier stage is connected between the collector of the first stage and the load so that when the switching transistor is made non-conductive by preventing current from flowing in its emitter-collector circuit but also makes the second stage non-conductive by reducing its base current to zero. Making the first stage non-conductive keeps it from amplifying the signal and requires any leakage current to pass around the first stage by means of stray capacitance. Making the first and second stages non-conductive simultaneously prevents even the leakage current from being amplified and allows the leakage current to reach the output terminal only by way of a second stray capacitance, which further reduces the amplitude of such current. A cascode stage may be included between the first and second stages to be rendered non-conductive along with them as a further means of amplifying the signal when the transistors are operative and decoupling the signal when the transistors are non-conductive. Instead of a simple cascode stage, a differential amplifier stage may be included between the first and second stages to provide means for adjusting the gain of the circuit.
Patent ES-420566-A1 (ES)
Title: Ignition system for an internal combustion engine with automatic timing shift
IPC: F02P5/155
Filed: 1973-11-15
Abstract: A timing pulse generator supplies the control current circuit of an electronically controlled switching element in the main current circuit of the ignition system over a full wave rectifier of which one half-wave branch includes a Zener diode preventing rectification unless the voltage exceeds its threshold value. The timing pulse generator provides a pair of succeeding pulses of opposite polarity at the end of each spark timing interval, the second pulse being of smaller amplitude. The Zener diode blocks the first pulse from the output of the rectifier at low engine speeds, so that the second pulse controls the timing. At intermediate engine speeds the first pulse overcomes the Zener diode voltage and takes over control of the timing, producing a jump advance of the spark timing. At high engine speeds a parallel combination of a capacitor and a resistor prevents the second pulse produced by the timing generator from interfering with the prompt quenching of the electronically controlled switching element in the main current circuit of the ignition system, because during the short timing interval the capacitor does not discharge fully through the resistor. By means of a switch, the first timing pulse can be loaded down to transfer the timing to the second pulse at high speeds during conditions when more complete combustion can thus be provided without sacrifice of needed power.

Title: Trigger mechanism for a power tool
IPC: H01H9/06
Filed: 1974-03-29
Abstract: An electromotor-driven power tool has a trigger mechanism controlling the operation of the electromotor. The trigger mechanism comprises a trigger constructed as an one-arm lever pivotable between an inactive and an active position in which latter it activates a switch controlling the supply of electric power to the electromotor. A latch member is supported in the trigger so as to be movable with respect thereto from a latching position in which it prevents the trigger from being displaced, to an intermediate position in which it permits displacement of the trigger into the active position thereof and its immediate return into the inactive position once a pressure exerted on the trigger is relieved, and beyond the intermediate position to a locking position in which the trigger is retained in the active position until the latch member is released either by deliberate action of the operator or by an impact.
