Patent ES-361596-A1 (ES)
Title: Apparatus and Process for Measuring the Lost Torque in a Closed Kinematic Chain
IPC: G01L3/14
Filed: 1968-12-18
Abstract: In a system for measuring the torque loss in a kinematic chain (10, 11, 12, 13, 14, 15, 101) the chain is closed upon itself by coupling the coaxial shafts 10, 101 to a driving pulley 17 using coupling devices each comprising at least one pair of element 24, 25 in cylinder-piston relationship of which (a) each pair defines a chamber 19 (20, 191, 201) operatively connected with fluid-pressure means 40 (401), 41 (411) and (b) one is rotatable with the pulley 17 and the other with the shaft 10 (101). The hub 23 of the pulley 17 is freely rotatable in the ends of shafts 10, 101 and has formed therein two pairs of diametrically opposite cylinders 24, 26 241, 261 at equal distances from the shafts 10, 101. Rollers 28, 29 carried by an end flange of shaft 10 on spindles 30, 31 are applied against the pistons 25, 27 in the opposite rotational sense to that in which rollers 281, 291 are applied against pistons 251, 271. The strokes of the pistons are limited in both directions by abutment of the pistons 25, 27, 251, 271 against shoulders 52, 54, 521, 541 and of the rollers 28, 29, 281, 291 at 53, 55, 531, 551 in recesses 50, 51 in the hub 23. A twisting moment can be introduced into the chain in static conditions by introducing hydraulic pressure into the chambers 19, 20, 191, 201, the pulley assuming a position of neutral equilibrium when the same pressure has been established in each direction. For a dynamic test the pulley 17 is driven by a band and, according to the direction of rotation, two chambers, say 19, 20 increase while 191, 201 decrease in volume, equilibrium being lost while the pressures remain equal due to the torque loss in the chain. The pressure difference required to restore the position of equilibrium with the pulley 17 floating between the abutments of the shafts 10, 101 is a measure of the torque loss from which the efficiency of the closed chain can be deduced. The equilibrium position can be detected stroboscopically by means of photoelectric cells. Methods of cancelling out errors due to friction are described involving averaging results of tests carried out successively in opposite directions. In another embodiment Fig. 3 (not shown) the shafts 10, 101 are concentric.

In another arrangement, Fig. 1 (not shown), valves 6, 7 are omitted and the simple check valves 11, 12 are replaced by stop check valves (1, 2).
Patent ES-369428-A1 (ES)
Title: Press bending of glass sheets
IPC: C03B23/031
Filed: 1969-07-11
Abstract: A glass sheet is bent to a required curvature between two relatively movable complementary bending dies which deform the glass sheet, which is heated to a temperature at which it is pliable. The respective overall heat losses from the two major surfaces of the glass sheet are adjusted during the bending operation so as to be substantially equal. For example, heat loss to one die may take place predominantly by conduction and the temperature of this die may be controlled, by means of heaters, to regulate the conductive heat loss associated with this die and effect the required heat loss balance.

Patent ES-389735-A1 (ES)
Title: Injection-control system for internal-combustion engine
IPC: G01F1/64
Filed: 1971-03-30
Abstract: To maintain optimum air-fuel ratio in a cylinder of an internal-combustion engine, the operating time of a fuel injector is controlled by a logic network responding to engine speed, temperature and load as determined by respective sensors. Engine speed is measured by a pulse generator, synchronized with the engine, whose pulses are fed to a spark plug in the cylinder, to a timing circuit in the logic network and to an ionization-type flow meter in the air-intake manifold. The output of the flow meter, integrated over a number of cycles, is applied to one input of a comparator via a circuit including a thermistor which serves as a temperature sensor, the other input of the comparator receiving a progressively rising reference voltage from a timing condenser which is charged from a constant-current source. The timing circuit includes a flip-flop, periodically set by a pulse from the generator, which is reset by the comparator whenever the condenser potential reaches the output voltage of the sensing circuit and which thereupon discharges the condenser, keeping it from recharging until the arrival of the next pulse. The flip-flop, when set, actuates the fuel injector by overlappingly energizing a biasing winding and a working winding thereof.

Patent ES-421453-A1 (ES)
Title: System for preventing intelligible crosstalk in TDM switching systems
IPC: H04Q11/04
Filed: 1973-12-14
Abstract: Apparatus is disclosed for protecting against intelligible crosstalk in a PCM-TDM system. Such crosstalk may arise when there is a failure in the system causing a mixing of signals in a first channel with signals from a second incoming channel. When the first channel is silent (sign bit zero and amplitude train zero) signals from the second channel may be added to the zero train causing the receiving subscriber of the first channel to receive undesirable crosstalk. To combat this situation, the invention employs two code conversion devices in series in a line. The first device inverts coded combinations having a sign bit 0 while transmitting without modification those with sign bit 1. The second device adjacent the output cancels the inversion of the first device to provide normal combinations to the called line.
