Title: Apparatus and method of operating a forced flow once-through vapor generating power plant
IPC: F01K3/22
Filed: 1963-11-19
Abstract: A forced flow once through vapour generator' e.g. a steam boiler heated by combustion gases and which can be started rapidly and with a minimum heat loss, consists of a feed pump 12 supplying working fluid from a deaerator 14 through a preheater 18 and an economizer 22 to a vapour generating section 24 and primary and finishing superheaters 26, 28 from which vapour passes through a turbine 30 to a condenser 32 with a shut-off valve 54 and a throttling valve 56 arranged in parallel to control the flow between section 24 and the superheaters. The starting method comprises closing valves 54, 56 opening a boiler shut-off valve 51 in an overflow conduit 50 to the condenser, supplying vapour from an auxiliary source 38 to the deaerator and circulating fluid through section 24 whilst the generator is being fired, until the clean-up operation is completed. A feed valve 20 is then closed and with valve 51 set to open at a given relief pressure, fluid is recirculated by pump 48 through section 24, at the same time the turbine is heated and rolled by vapour from source 38 which first cools the superheaters. When the fluid in section 24 reaches a given temperature and pressure above those in superheater 26, valve 56 is gradually opened by an amount which ensures that all the fluid passing into the superheater immediately vaporizes, feed valve 20 is opened to pass an equivalent flow into section 24 whilst the auxiliary vapour flow is reduced by closing valve 43. When the pressure drop across valve 56 becomes negligible, then valve 54 is opened and valve 43 is closed to establish normal operating conditions. In another embodiment another superheater is placed between the vapour generating section 24 and valves 54, 56 between intersections of conduits 44 and 50.

Patent ES-310842-A1 (ES)
Title: Oxidation method of producing glass having an increased breaking strength
IPC: C03C21/00
Filed: 1965-03-22
Abstract: A method of producing glass having an increased breaking strength comprises causing the surface layers of the glass, rich in reactive elements or compounds which are chemically in a reduced state, to react with and take up one or more further elements or compounds which are in contact with the glass at a temperature near or below the strain point of the glass to introduce said one or more further elements or compounds into the surface layers of the glass, whereby there are formed in the glass surface layers of compression. In a preferred embodiment flat glass which is produced by the "float" technique dissolves stannous oxide in its surface layers. This is achieved by the molten tin bath having an oxygen content of 50 p.p.m., and allowing stannous oxide vapour to contact the upper surface and sides of the ribbon. After removal from the bath of molten tin the ribbon is cooled and then maintained in an atmosphere of oxygen of 10 atmospheres pressure at a temperature of 450 DEG to 550 DEG C. to convert the stannous oxide to stannic oxide. If cut glass sheets are used they may be immersed in a bath of molten tin or held in an atmosphere of stannous oxide vapour. Alternatively other compounds of variable valencies may be used, for example lead, manganese, and vanadium, and the element taken up may be of sulphur or chlorine. The glass with the stannous compound in the surface may be bent in an inert atmosphere before the further treatment.

Title: Deflection circuit with frequency dependent negative feedback
IPC: H03K6/04
Filed: 1966-12-07
Abstract: A field deflection circuit is driven by a control signal having sawtooth and parabolic components, the circuit being directly coupled to deflection coil 20 and having a direct current negative feedback path arranged to provide selective attenuation of low frequencies in the output. As shown, the output of a sawtooth generator 1, synchronized by field pulses 4, is integrated so as to provide a parabolic component giving a composite waveform 2 which is passed via an optional capacitor 5 and a driving transistor 7 to a complementary transistor output stage 12, 13 feeding field deflection coils 24. The scan is linearized by feedback via a highpass filter 20, 21. A direct current feedback path is provided via resistor 28 so as to minimize the effect of sudden changes in amplitude from source 1. Transistors 12, 13 operate in class B push-pull, the standing current being adjustable at 30. A negative temperature coefficient resistor 11 provides temperature compensation for the output transistors 12, 13. A diode 17 and capacitor 18 permit free oscillation of the deflection coil 16 during the flyback. If capacitor 5 is omitted, attenuation of low frequencies may be achieved by a resistance/capacitance emitter circuit for transistor 7. Modifications.-The collectors of transistor 12, 13 may be commoned instead of their emitters. Output transistors 12, 13 may be of like conductivity if a driver transformer or a complementary pair of driving transistors is provided. Driver transistor 7 may be omitted or replaced by an FET. Transistor 13 may be replaced by a choke.
Patent ES-342071-A1 (ES)
Title: Spinning machines having hydraulically controlled ring rails
IPC: D01H1/36
Filed: 1967-06-20
Abstract: The upward movements of the ring rail 7 of a spinning machine are effected by hydraulic pressure in a single-acting motor 17 acting through belts 12, 9 under control of a valve 24 which controls the pressure in the outlet 23 of a constant delivery pump 20 by the relief of pressure through a return pipe 22. The downward movements are effected by gravity. The normal reciprocating movement of the rail is obtained by a cam 37 acting on valve 24 through belts 27a, 27b, with a follow-up from the rail via a roller 32 acting on one end of the belts. The successive offsets of height of the rail is obtained by a drum 28 acting upon the end of belt 27a. The hydraulic control circuit also includes electromagnetic valves 40, 41 and 43, a pressure relief valve 46 and a check valve 48. The valve 40 is adapted to close outlet 23 to valve 24 so that a rapid build-up of pressure in motor 17 can be obtained for a quick upward movement of the rail. Valve 43 supplies pressure to a motor 39 to release the machine brake F. Valve 41 is opened for a quick release of pressure and a quick downward movement of the rail. These valves are operated for initial and final larger movements of the ring rail in the build-up of a cop.

Patent ES-370413-A1 (ES)
Title: Method and apparatus for manufacture of float glass
IPC: C03B18/16
Filed: 1969-08-11
Abstract: Thick float glass, e.g., from 8 mm. to 30 mm. thick, is produced by physically halting the lateral flow of the glass when it achieves a predetermined thickness, the layer of molten glass being thermally controlled by causing transverse flow of molten metal beneath the glass and then confining to the sides of the bath downstream flow of that molten metal and permitting dispersal of the confined flows of molten metal into a downstream region of the bath. This method is accomplished by a float glass apparatus having longitudinally extending fenders, the section nearer the entrance being spaced from the floor so a pump may pump liquid in the bath transverse to the sheet of glass being formed.

Title: Improvements in or relating to methods and machines for grinding crankshafts
IPC: B24B5/42
Filed: 1969-08-27
Abstract: A method of grinding a crank-shaft comprises mounting the crank-shaft 3 non-rotatably in supports 2 leaving free access all round a crankpin 18 to be ground, driving a flexible abrasive belt 22 by means of one of a pair of pulleys 21A, 21B between which the belt is trained with the abrasive surface facing outwards, orbiting the belt and pulleys round the crank-pin, and moving one of the pulleys towards the crank-pin to cause contact between the crank-pin and belt where the latter is in contact with the pulley. In a machine for carrying out the method, the crank-shaft is secured by split bearings 15 to the supports 2 which are mounted on adjustable cross-slides 6 carried by saddles 4 interconnected by a shaft 5 for movement in unison on a base 1. A frame 7 straddles the base and rotatably supports an annular carrier 8 having guideways 19 for a radially adjustable slide 20A. An electric motor 24 drives one of the pulleys 21B and the other pulley 21A is mounted on a plate 29 which is adjustable about the axis of pulley 21B to bring the abrasive belt 22 entrained about the pulleys into engagement with the crank-pin 18, the plate being fixable in adjusted position by a bolt 30 passing through an arcuate slot 31 in the plate 29. A jockey pulley 23 is provided for tensioning the belt. In operation, the crankshaft is mounted on the supports 2 and the pulley 21A adjusted to engage the belt with the crank-pin. The carrier is rotated so that the belt orbits the crank-pin as it is driven over the pulleys by the motor 24 which receives its power from contacts 27 co-operating with rings 26. The crank-shaft is moved axially so that the belt traverses the crank-pin by a motor 9 driving a lead screw 12 to move the saddles 4 along the base 1. A second slide 20B may carry means for grinding and polishing the faces of the crank webs. The grinding may be effected wet, a pump, supply pipes and drain circulating coolant which is cleaned by a centrifuge or magnetic separator.

Title: Shear
IPC: B23D31/04
Filed: 1972-01-21
Abstract: The disclosure of this invention relates to a shear for side trimming or dividing steel plates produced by a rolling mill. It illustrates and describes a stationary lower knife head to which there is secured a lower knife and a vertically movable upper knife head that support an upper knife. The upper knife head is connected to a crank shaft by pitmans and through which means the upper knife is moved towards and away from the lower knife to effect a cut. The path of the shearing and return stroke of the upper knife head is controlled so that during the cutting portion of the shearing stroke, the upper knife is caused to move perpendicular to the plate over the entire range of plate thicknesses adapted to be sheared, and immediately thereafter, at the commencement of the return stroke, the upper knife is displaced away from the sheared edge of the plate. This control is achieved by providing a pair of trunnions pivotally connected to the upper knife head in which the upper knife head is urged against a knife action control guiding surface during the shearing stroke and displaced laterally immediately after shearing and during the first portion of its return stroke in a manner that the lower portion of the head is tilted away from the sheared edge of the plate. A piston cylinder assembly connected to the upper knife head is employed to assist in the positioning of the head in timed sequence with the rotation of the crank.
