Title: Method and apparatus for winding yarn
IPC: D01H1/04
Filed: 1967-09-06
Abstract: A package 15 of synthetic plastics tape drawn from a controlled speed supply source is wound on a non-rotary support 34 by a winding guide 47 (e.g. on a flyer 12) driven round the axis of the support so as to insert one turn of thrust for each revolution of the guide. Thus when the tape is drawn off over-end e.g. in a loom, the drawn-off tape is twistless. As shown spindle 14 carrying the flyer is driven from a pulley 26 which transmits drive to a clutch plate 29 on the spindle through friction pads 28. Pads 28 are radially movable so that as the package grows the torque applied to the spindle is lessened and the tension in the tape is kept constant. Other types of slipping drive may be used. The tape passes to the flyer over a pulley 45 close to the top shoulder 46 of the flyer thus each twist inserted in the tape is localized. The flyer is provided with a selfthreading guide roller 47 and a co-operating pivoted wire arm which lays the tape on the package. The packags build is derived from the reciprocation of a rail 20 and associated shaft 40, the reciprocation being transmitted by a bar 38. To obtain shaped package ends shaft 40 is intermittently rotated so that a gear thereon engaging a rack on bar 38 shifts bar 38.

Title: Method of operating mercury cathode electrolytic cell plant
IPC: C25B1/36
Filed: 1968-01-27
Abstract: In operating plant comprising flowing mercury cathode cells through each of which an electrolyzable salt solution (brine) is continuously recycled, a concentrated solution being fed to the cell and a depleted solution being withdrawn from it, in order to increase the operating efficiency by increasing the electrolyte flowrate through the cell and reducing the temperature and concentration differences between the feed and return streams without increasing the load on ancillary resaturation and purification equipment, at least one third of the depleted solution is recycled back to the cell without chemical treatment while the remainder is recycled via a resaturating and purification plant. As described the mercury circuit including a denuder of each cell is independent, but the brine, typically sodium or potassium chloride solution, may be fed from a header common to all the cells. Typically up to nine-tenths of the depleted solution may be recycled without chemical treatment. Either the whole (see Figs.1, 2 not shown) or at least a part of the resaturated salt stream is combined with the untreated stream before recycling to the cells. The combined solution stream may be introduced at one or more points intermediate the cell ends in addition to the upstream end of the cell (see Fig. 2). As shown combined solution stream is introduced at the upstream end and saturated solution is introduced at an intermediate point along the cell such as by pipe 16 and sparger 19. The cell is of the kind described in Specification 894, 769 in which graphite anodes 6 are supported by graphic rods 7 secured to a metal spider 11 secured to a beam 24 which is attached to bars 5 adjustably secured to posts 4 seating on the top flange 3 of the electrolyte trough 1. The anodes are provided with longitudinally directed slots 21 which communicate with gas escape holes 22 and baffle plates 20 are supported across the cell between groups of anodes, especially at locations where electrolyte is introduced, to effect stirring of the bath and so assist in gas removal and renewal of electrolyte between the anodes and flowing mercury cathode. The top of the cell is closed by a flexible rubber or plastics sheet through which the connections to the anode rods 7 and the electrolyte supply pipe 16 pass. A gauge 17 which may include means for automatic flowrate control and a manual valve 18 are also provided. On start-up the heat exchanger J may be operated so as to warm the brine fed to the cell while on shut-down with the arrangement shown in Fig.3 the cell is preferably fed with pure brine through the inlet end by suitable operation of valves K, L, M.

Title: Tube leak detector
IPC: F22B35/10
Filed: 1969-03-14
Abstract: In a forced flow steam generator having a tube system with at least two parallel fluid flow paths each containing the same number of series connected heating surfaces 5, 51 . . . 12, 121 of substantially identical construction, a tube leakage detector system is provided which compares the values of an operating variable of the working medium, e.g. pressure or temperature, at corresponding points in each of the flow paths and transmits a signal if the comparison indicates a leak. In the embodiment shown devices 25, 26, 27 measuring the pressure difference in the connecting lines between economiser, evaporator and first and second super heater heating surfaces 5, 51, 8, 81 and 10, 101 and 12, 121, respectively, are connected to respective transducers 28, 29, 30 and indicating instruments 31, 32, 33. Should a leak occur and the deflection of the indicating beam of an indicating instrument be such, due to the pressure difference, that a limit contact 41, 411 ... 43, 431 is touched by a contact blade connected to the beam, an associated alarm 36 ... 38 is actuated. In a steam generator with four parallel fluid flow paths a mean value for the pressures in the four paths may be formed by connecting the paths through respective restricted lines (70 ... 70111), Fig. 2 (not shown), to a pressure equalizing vessel (72) also connected to the paths through pressure difference measuring devices (73 ... 73111) with indicating beams responsive to any pressure difference caused by a leak. The signals of comparison may be fed to a digital computer which when a leak occurs decides whether the steam generator should be switched off or merely a warning given. A feed water control valve 3 is controlled by a unit 17 connected to a flow meter 18 and temperature sensors 15, 151. Valves 47, 47 in attemperator water lines 46, 461 are controlled by a unit 21 connected to a temperature sensor 20.
Patent ES-371470-A1 (ES)
Title: Electric driving arrangement using a stepping motor
IPC: H02P8/24
Filed: 1969-09-12
Abstract: When a controller ,l0 receives a forward or reverse starting signal, it generates a pulse E which is transmitted to ring counter 3 through gate 4, and sets a bi-stable switch 6 to open a gate 5. Simultaneously, the controller 10 transmits a signal U to the ring counter 3 which commences counting in the desired direction. A stepping motor 1 is accelerated to its next position in which a photo-electric pulse generator 12-14 develops pulse G which is applied to the ring counter through gates 5 and 4. The ring counter further advanced so that the motor moves to its succeeding position. The pulses G are applied to controller 10 to be counted and compared with the number of steps the motor is to travel. A number of steps before the motor reaches the desired stopping position, the controller 10 develops a deceleration pulse F which changes over the switch 6. The next pulse G does not pass through the gate 5 but is applied to a delay circuit 7 which produces a signal T, the delay time of this circuit being greater than the interval between two successive pulses G at this stage. Pulse gate 8 now passes the pulses G through OR- gate 9 and the gate 4 to the ring counter 3 whereby the motor is decelerated since it tends to be retained in its preceding position. When the time between two successive pulses G exceeds the delay time of the circuit 7, the gate 8 is closed and the motor assumes a speed which depends upon the delay time, but it cannot step backward. The controller 10 the develops a signal W to close the gate 4 and stop the ring counter 3, the motor being stopped within a single step.

Title: A process for the manufacture of phenazine derivatives
IPC: C07D241/52
Filed: 1970-04-21
Abstract: The antibiotic myxin, and other 1-hydroxy-6- alkoxy-phenazine 5,10-dioxides in which the alkoxy group has 1 to 7 carbon atoms, are prepared by reacting a mono-alkali metal salt of 1,6-dihydroxyphenazine 5,10-dioxide iodinin with an alkylating agent in an aprotic polar organic solvent for the salt and recovering the 6- alkoxy compound. The preferred solvent is hexamethylphosphoric triamide, or dimethylformamide or dimethylsulphoxide may be used. The alkali metal salt (e.g. Na or K) may be prepared in situ in the aprotic solvent by reacting iodinin with an equimolar amount of alkali metal alkoxide therein. Alternatively it is prepared by treating iodinin with an excess of aqueous alkali metal hydroxide, filtering off the required salt and drying it. Alkylating agents may be dialkyl sulphates, alkyl iodides, or alkyl tosylates. The 6-alkoxy compound is recovered from the aprotic solvent by addition of ice-water or a non-solvent such as chloroform and is purified e.g. by chromatography on silica gel or alumina. 1-Hydroxy-6-(3-methylbutoxy)-phenazine 5,10- dioxide is prepared by alkylating the potassium salt of iodinin with 1-bromo-3-methylbutane in hexamethylphosphoric triamide. Reference has been directed by the Comptroller to Specification 1,177,697.

Patent ES-421762-A1 (ES)
Title: Scanning light synchronization system
IPC: G06V10/12
Filed: 1973-12-24
Abstract: A scanning light synchronization system generates a real time clock, the output signal of which indicates the precise position of a scanning light beam. A collimated light beam is diverted by a multi-faceted rotating mirror in a scanning direction. The scanning light beam is split along two paths by a light diverter: a utilization path and a synchronization path. That portion of the light beam traversing the synchronization path scans an optical grating. That portion of the light beam passing through the grating is thereafter reflected from the surface of an elliptical mirror to a light detection device. The elliptical mirror is positioned so that its first optical foci is located at the diversion point of the scanning mirror and its second optical foci is located at the light detector. The light detector provides an output signal indicating the real time position of the scanning beam traversing the utilization path. This output signal is utilized with stored information to modulate the scanning beam so that the light beam traversing the utilization path creates an image on a light receptive surface. The output of the light detection device is also utilized in conjunction with light reflected from a document surface placed in the utilization path to effect the clocking of information signals obtained from such reflected light.
