Patent ES-340477-A1 (ES)
Title: Method and apparatus for float glass dross entrapment
IPC: C03B18/18
Filed: 1967-05-12
Abstract: In the manufacture of flat glass in which glass 8 in ribbon form is advanced down a central region of a bath 1 of molten metal 3, exposing strips of the molten metal surface at each side, controlled surface flow of the exposed metal is induced electromagnetically into a region 11 of the bath where dross carried thereby is collected on the metal surface 12. Two linear induction motors 13 are mounted just above the level of the surface of the bath over the exposed strips of molten metal and near the outlet end of the bath. The motors are fixed to the end of a cantilever beam 14 which permit adjustment of the gap between the motor and the surface of the bath, and also carry electrical connections and pipes for cooling fluid. The said motors induce a controlled surface flow of molten metal as shown by arrows 15 and these flows carry dross along the exposed surfaces of molten metal towards the outlet end of the tank structure. Auxiliary linear induction motors 16 are mounted above the inlets to recesses 11 to divert the surface flows into the recesses and hence into the pockets 12 of molten metal, Alternatively a linear motor is arranged just above the ribbon near the exit end of the bath so as to drive dross forwardly against the outlet end wall 2 of the tank structure. On striking this wall the surface flow is diverted laterally into the pockets 12.

Title: Method of rendering polyester materials resistant to attack by ultraviolet light
IPC: D06M13/35
Filed: 1967-05-31
Abstract: Textile material made from polyesters formed by the reaction of a polybasic acid and a polyhydric alcohol is rendered resistant to attack by ultraviolet light by immersing it in a heated bath containing an ultra violet light absorber and a liquid carrier which acts as a catalyst so that the ultraviolet light absorber reacts chemically with the polyester material, removing the material from the bath and heating the material to a temperature in excess of the flash point of the carrier liquid to remove any carrier liquid remaining on the material. The ultraviolet light absorber may be a mono-ortho-hydroxybenzophenone or orthohydroxyphenyl-benzotriazole, benzotriazole or phenyl alpha methyl styryl ketone and the carrier may be ethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol, butylene glycol, glycerol, a glycol ether or a polyglycol. The bath is preferably heated to at least 250 DEG F and the polyester material may be immersed in the bath for 2-30 seconds. The carrier liquid may subsequently be removed by heating the material to a temperature in excess of the flash point of the carrier liquid by passing the material through a hot air stream. The textile material may be in the form of a filament, yarn, tow or woven or knitted fabric, and may be used in the production of sails, tents, awnings, articles of clothing or rugs.
Patent ES-343691-A1 (ES)
Title: Data set for polar current loop signaling
IPC: H04L25/22
Filed: 1967-07-20
Abstract: An apparatus for detecting polar signal current in a two-wire loop subject to longitudinal current, i.e. to currents in both wires in the same direction and of the same magnitude, comprises first and second means for sensing the magnitude of the incoming and outgoing currents, respectively, in the two wires, and means responsive to the outputs of the sensing means for producing an indication of the magnitude and direction of the signal current. Single current signals from a teleprinter at 101 pass via gate 102 to transmitter 108 (described below) which develops polar signals for transmission over two-wire line 111, 112. Monitor 118 gives a signal on output 119 indicating the total magnitude of spacing current, if any, on lines 111, 112, and on output 120 indicating the total magnitude of marking current. If the longitudinal current is sufficiently high the current in one wire will be reversed. The difference in the potentials on 119 and 120 indicates the state of the polar signal and is determined in receiver 202 which comprises a differential amplifier. The receiver output is a single current signal which passes via gate 210 to a teleprinter at 201. Unit 205 (described below) determines from the outputs of monitor 118 whether the loop current is above or below a given threshold, and provides indication of signal failure. When either station at the ends of the loop is idle it delivers a marking current to the loop. The current delivered by a station when transmitting a Mark is equal to the idle current and when transmitting a space is three times the idle current. If the remote station is not transmitting, gate 102 passes the single current signals both to transmitter 108 and to unit 104. The latter unit provides an inhibit signal to gate 210 whenever a Mark is transmitted to prevent that Mark from being recorded in the local teleprinter. Gate 210 is also inhibited if unit 205 indicates signal failure. Gate 102 clamps the transmitter to Mark when the remote station is transmitting. Transmitter 108.--When a positive (Mark) signal is applied at line 103 transistors Q1, Q2, Q3, Q4 are non-conductive and current flows from positive via R8, CR5, CR7, reversely poled diodes RV4, and CR6, to negative. The voltage drop across the lines 111, 112 is determined by CR7 and RV4. When earth (Space) is applied at line 103, Q1-Q4 are conductive and current passes from positive via RV2, Q4, RV4, RV3, breakdown diode CR8, Q3 and RV1, to negative. The potential across CR8, RV3, RV4 is three times that across CR7, RV4 in the Mark state, so providing a 1: 3 Mark: Space current. Signal fail unit 205.-When the potential on line 120 is sufficiently positive relative to that on 119, the potential between the emitters of Q12 and Q1 5 causes diodes RV16 to conduct, current flowing via Q12 and Q15. The resulting voltage drop at the collector of Q15 causes Q16 to be non-conductive. Similarly Q13, Q14 conduct when the potential of lines 119, 120 reverses. The unit provides an output from Q16 only if the signal level is too low.

Filed: 1970-06-30
Abstract: In the float glass process, particularly for very thin glass of the order of 3 mm. or less, a predetermined thickness of the glass less than the equilbrium thickness is obtained by gripping the edges of the glass ribbon using knurled rollers 27 to resist the longitudinal tractive force produced by rollers 22, 23 located downstream of the outlet 20 of the float tank 5, re-heating the ribbon in a region 35 downstream of the rollers 27 while simultaneously cooling the edge regions of the ribbon using coolers 44, 45, 46, so that the viscosity of the central band is at least onefortieth of that of the edge regions while maintaining the viscosity of the edge regions sufficiently low so that they may still be drawn. Means, such as rollers 81 and obliquely mounted rollers 37 may be provided in the region 35 to prevent shrinkage of the ribbon width.

Title: Adjusting mechanism for radially movable tools in rotary tubular tool holders of shaving machines for wire or the like
IPC: B23B29/034
Filed: 1971-07-03
Abstract: A shaving machine for rolled wire or the like wherein the tubular shaving head carries one or moreshaving tools which are caused to move radially in response to axial movement of an adjusting sleeve which is connected to the inner race of an axially movable antifriction bearing spacedly surrounding the shaving head. The outer race of the bearing is provided with annuli of equidistant plenum chambers which are sealed by a stationary ring-shaped guide surrounding the bearing and having conduits for admission of pressurized fluid into the plenum chambers. The plenum chambers serve as a stabilizing or cushioning means for holding the bearing against radial movements with reference to the frame. The adjusting sleeve is loosely coupled to the shaving head so that it rotates with but need not share vibratory or other stray movements of the shaving head. This insures that such stray movements need not be shared by the tools whose supports are biased against a conical internal surface of the adjusting sleeve.
