Title: An improved method for the continuous selective hydrofining of crude petroleum in the liquid phase
IPC: C10G45/22
Filed: 1959-10-13
Abstract: Crude petroleum is hydrofined in the liquid phase by contacting a mixture of hydrogen and the crude oil with a catalyst selected from the oxides and sulphides of chromium, molybdenum, tungsten, iron, cobalt and nickel at 300 DEG -395 DEG C. and a pressure of 55 - 120 kg./cm2.

Title: Rotary capacitor with insulated electrodes
IPC: H01G5/08
Filed: 1967-03-20
Abstract: In a variable capacitor comprising rotor plates 3 and stator plates 5 separated by plastics dielectric layers 7 mounted in a framework of moulded insulating material consisting of front and rear plates 9 and 11 connected by rods, each comprising portions 13, 15, the rotor shaft 1 is journalled in metal plate 17 to eliminate sticking due to expansion of the plastics material, and two of the frame rods serve as supports for the stator plates 5 (Fig. 1, not shown), these tubular rods having a central bore 19 through which passes a bolt 21 screwed into an aperture 23 of metal plate 17 to clamp it to the front frame plate 9. A projection 27 of a metal ring 29 secured to a flange 31 on the rotor shaft co-operates with a segment-shaped cavity in the front plate 9 to limit the rotation of the rotor shaft. A polythene washer 33 separates the flange 31 from metal plate 17 and a wavy metal ring 34 around the flange and between ring 29 and the flange serves as a sliding contact between the rotor and tongue 35. Portion 13 of a frame rod supporting the stator plates has a narrow part 41 passing through tongues 43 of the stator plates, these tongues being separated by metal spacer rings 45 which electrically connect the stator plates. The narrow part 41 fits into a wider portion 47 of axial bore 19 of portion 15 of the frame rod. Correct alignment of the rotor shaft with front plate 9 during assembly is achieved by fitting pins through aligned openings 37 and 39.

Patent ES-350055-A1 (ES)
Title: Device for the automatic gain control and clamping of the black level for television receivers
IPC: H04N5/18
Filed: 1968-02-01
Abstract: In a television A.G.C. circuit video signals with the sync. pulses negative going are fed to an emitter-follower 2 the output of which is connected to a diode gate 10, to the anode of which line flyback pulses are applied from terminal 35, via resistors 20, 11. The diode 10 is thereby gated to conduct during the backporch periods, the pulses appearing at the anode being fed over a two-stage D.C. amplifier comprising transistors 21, 25 and a smoothing capacitor 29 to the gain control signal output terminal 32. To the output of emitter-follower 2 is also coupled sync. separator 5, the output of sync. pulses from which, on line 6, are also applied via a potentiometer 7, 8 to the base of a clamping transistor 9. The collector-emitter path of this is connected across the join of resistors 11, 20 and earth, and in this way the transistor 9 prevents the line flyback pulses operating the diode gate 10 during the sync. pulse periods. Video signal is also fed to output terminal 33 from the emitter follower 2 via capacitor 15, the D.C. level being restored by means of a clamp circuit comprising diodes 17, 18 connected in series. The clamping level is determined by means of a potentiometer 13, and clamping is performed by means of line flyback pulses obtained via resistor 19 from the join of resistors 11, 20. In an alternative arrangement (Fig. 4, not shown) the clamping diodes are replaced by the emitter-collector path of a transistor (40), the clamping pulses being applied to its base and also to the black-level clamp, via differentiating circuits which are provided to narrow the clamping pulses: this renders the arrangement suitable for use with a synchronization system using phase comparison, in which a phase angle may occur between the sync. pulses and line flyback pulses.

Title: Transistorized ignition system for internal combustion engines
IPC: F02P7/073
Filed: 1968-03-22
Abstract: An ignition system comprises an ignition coil 16, 18, an electronic switch 15, normally maintained in the non-conductive state, connected in series with the primary winding 16 of the ignition coil, a control device 14 for controlling the electronic switch and a contactless signal generator 13, for controlling the control device in timed relation to the rotation of the engine and thereby periodically switching on the electronic switch and switching it off again at the instant of ignition whereby current in the primary winding 16 of the ignition coil is interrupted and a high tension pulse is triggered in its secondary winding 18 for producing a spark at a sparking plug 11. The contactless signal generator and the control device are adapted to maintain the electronic switch conductive for an increasing proportion of the time interval between two successive ignition operations by advancing the instant of switching on the electronic switch relative to the instant of switching off in dependence upon engine speed at least over a part of the operating speed range of the engine. The signal generator 13 and control device may control the duration of the flow of current through the primary winding of the ignition coil in at least the lower engine speed range so that the duration is substantially constant. As shown the signal generator 13 is magnetically operable but in a modification not shown, it employs a photo-cell. Signal generators can be constructed having magnetic field dependent resistors. The ignition timing may be controlled centrifugally.
Patent ES-356569-A1 (ES)
Title: A starting circuit for a single-phase asynchronous motor
IPC: H02P1/44
Filed: 1968-07-27
Abstract: To improve the torque provided by a singlephase asynchronous motor having a PTC resistor in series with the starting winding, a capacitor is connected in parallel with the resistor. The low resistance of the cold PTC resistor first acts as a starting resistance and then when warm the resistor virtually switches the starting circuit to pure capacitance. An ohmic resistor may be in series with the PTC resistor to protect the latter.
Patent ES-373994-A1 (ES)
Title: Continuously operating centrifugal separator
IPC: B04B3/00
Filed: 1969-11-27
Abstract: The imperforate conical basket of a centrifugal separator carries a conical, mainly imperforate skirt which depends from the upper basket rim into the liquid receptacle bounded by the basket and by a stationary partition in the separator casing. The liquid flowing upwardly between the inner basket wall and a screen enters recesses at the top of the basket at least partly bounded by the skirt and is led to the inner skirt face. It is discharged centrifugally from the free lower edge of the skirt against a conical baffle attached to the partition and downwardly bounding an isolating chamber radially confined between the outer skirt face and the partition. Contamination of the discharged liquid with simultaneously discharged solids is prevented, air cannot carry the discharged liquid into the separated solids nor vice versa.

Title: Apparatus and method for detecting and reporting ends down on textile machines
IPC: D01H13/14
Filed: 1970-08-08
Abstract: The ends down condition of spinning machines is detected by a travelling unit comprising a detector for the ends down condition, and a means responsive to the data sensed by the detector for determining the ends down condition of a traversed machine and indicating and reporting the existance of such an unacceptable number of ends down. As described, a cleaning unit has a mechanical, photoelectric or sonic detector of the ends down condition of the spindles in one of a plurality of frames. The number of broken ends in any one of the frames is counted electronically (Fig. 11) using light or sound waves or mechanically by physical contact (Fig. 13). The number of ends down is counted electronically or by a solenoid operated ratchet end pawl device (Fig. 15) and after a predetermined number has been counted, a stationary data collector is signalled so as to light a lamp at the end of the machine frame, e.g. in the aisles between machine frames. The lamps can be manually extinguished. The counting device for the broken ends can be automatically reset to zero at the end of the. machine frame and may have an overriding cut-out which. operates when the sensing head meets an obstruction or when it reaches the end of the frame or when it passes between spindles. Reference has been directed by the Comptroller to Specification 1,205,823.
