Patent ES-274835-A1 (ES)
Title: Apparatus for tracing and breaking glass sheets
IPC: C03B33/027
Filed: 1962-02-22
Abstract: An apparatus for cutting a glass sheet comprises a scoring tool, a conveyer to bring the sheet into an operative position, means to operate the tool so as to score the sheet on one surface thereof in the operative position and breaking means operable to exert pressure on the sheet in the operative position on the other surface of the sheet along a line in alignment with the score line and on the one surface on either side of the score line. The apparatus comprises an entry conveyer consisting of rolls 2, a scoring and breaking section and an exit conveyer with a plurality of belts 5. A transverse carriage 9 mounted on longitudinal rails 8 and movable by a hand wheel 10 carries two identical units each comprising a stop 11 with a plastic covering 12 on a lever arm 13, a stroke limiter 15, a pneumatic ram 16 and a contactor 20 (Fig. 5, not shown) adjacent the front face of the stops 11. A motor-driven carriage 23 mounted on slides of a beam 22 carries a tool holder 25, of the kind described in Specification 863,113, with a cutting wheel acting in the vertical plane X-X. Two freely rotatable vertically adjustable short rolls 27, 28 are mounted in a frame member 26 and two other <PICT:0990863/C1/1> short rolls 29, 30 are carried by arms 31 of a ram 32. The rolls 27, 30 lie behind rolls 28, 29 respectively in Fig. 1. The ends of a rubber sleeved metal tube or as shown a U-sectioned member with resilient elements are mounted on the heads 37 of two pneumatic rams 39. In operation a glass sheet 1 placed on the entry conveyer 2 closes a contactor 4 which starts the motors driving the entry and exit conveyers. As the sheet 1 travels it operates the contactor 20 which, after a time delay to allow the leading edge of the sheet 1 to abut the stops 11, stops the conveyers. Rams 16 operate to cause the stops 11 to take up a position defined by the stroke limiters 15 and so slightly displace the sheet 1 to render it exactly parallel to the longitudinal axis of the machine. A sensing device moves towards the lateral edge of the sheet and a stop on this device on contacting the sheet 1 closes a contactor causing the cutting tool holder 25 to descend just beyond this point, and also returns the sensing device to its starting position. As the cutting tool contacts the glass sheet 1 a contactor closes and causes strong pressure to be applied by the tool to the glass and also starts the movement of the carriage 23 whereby a score line is made on the glass sheet 1. When a feeler member on the tool holder leaves the edge of the sheet, and just before the scoring tool reaches the edge, the carriage is stopped and the tool holder raised. This closes a contactor which causes the carriage 23 to return, the stops 11 to be raised, the rams 39 to operate to raise the breaking member and the exit conveyer to restart.

Title: Dual loop antenna
IPC: H01Q7/04
Filed: 1964-10-03
Abstract: An aerial consists of at least two co-planar rectangular loops, the longer sides of which are all parallel and are, for the most part, enclosed in tubes of ferromagnetic material. As described, a single conductor is wound anticlockwise to form one loop with sides 13, 14, 15, 16 and then clockwise to form another loop with sides 17, 18, 19, 20, the long sides 13 and 17 of the two loops being adjacent. Ferrite tubes 22, 23, 24 enclose one long side 15 of one loop and the two long sides 17, 19 of the other. The ends of the conductor 10 are taken to terminals 11, 12. A plastics sheath 25 encloses the aerial and comprises a central tube from which tubular portions branch off for containing the outer portions of the loops. The sides of the loops, and the ferrite tubes, may be secured in the various tubular portions of the sheath. The inner conductor and the sheath of a coaxial cable 25 may be connected to the terminals 11, 12 or only the inner conductor may be connected to one or both of the terminals, the sheath being connected to it through a matching resistor (Figs. 2 and 3, not shown). It is stated that the aerial will receive signals satisfactorily over a broad band of frequencies, such as from 50 to 200mc/s., and that it exhibits directivity which may be utilized for weak signals.
Patent ES-341083-A1 (ES)
Title: Coaxial horns with cross-polarized feeds of different frequencies
IPC: H01Q5/45
Filed: 1967-05-27
Abstract: A waveguide arrangement for transmission of up to four signals in multiplex comprises an inner circular waveguide 1 for transmission of two orthogonally polarized H 11 waves at frequencies within an upper band, and a surrounding coaxial waveguide 2 for transmission of two further orthogonally polarized H 11 waves at frequencies within a lower band. The signals are fed towards a horn 11, 12. The lower-band signals are fed to the coaxial guide through two rectangular waveguides 4, 5 arranged on orthogonal axes and coupled to the coaxial guide by tuned irises 6. In order to prevent backward propagation, pairs of conductive fins 7, 9 (one only of each pair visible) are arranged immediately behind the irises in planes parallel to the electric vector of the waves they are intended to reflect. Any energy propagated in the backward direction is absorbed by a termination 3. Upper-band signals are fed to the inner guide 1 by any known means. In order to isolate the two bands when the apparatus is used for reception, the diameter of the inner guide is such that only the upper frequency band will propagate in it. In addition, the coaxial guide is provided with a filter 13 to reject signals in the upper band. This consists of dielectric annuli spaced apart by a distance #/2 at the desired rejection frequency. The annuli also provide an impedance match between the waveguide and the horn. In order to correct irregularities in the polarization of the waves, each waveguide is provided with an annular clamp (Fig. 4, not shown) designed to produce a local deformation of the waveguide.

The isocyanates may then be converted directly into the urea derivatives or they may be isolated and purified. A described purification process comprises heating the isocyanates to about 50- 100 C., whereby a solid insoluble polymer is formed from which monomeric impurities may be removed by trituration with solvents the isocyanates are then regenerated from the polymers by heating the latter to 200 C. or above under reduced pressure. Reaction (b) may be effected at 0-100 C., optionally in the presence of a solvent which may (but need not) be an aprotic polar solvent. Examples are given of the manufacture of m- and p-isocyanatophenol, 2,6 - dichloro - 4 - isocyanatophenol, 1 - (4 - hydroxyphenyl) - 3 - isopropyl urea, 1 - (3 - hydroxyphenyl) - 3,3 - dimethyl urea and 1 - (3 - hydroxyphenyl) - 3,3 - diethyl urea. Many other products of the invention are specified. The urea derivatives are useful, e.g., in the manufacture of ureidophenyl carbamates for herbicidal use.
Patent ES-356337-A1 (ES)
Title: Carrier current telecommunication system
IPC: H04J1/14
Filed: 1968-07-20
Abstract: In a carrier current communication system, e.g. a " Rural carrier " system, signalling information, such as metering pulses, are transmitted by sending either a carrier and lower sideband speech signal or a carrier and upper sideband speech signal, the carrier being shifted between the two conditions so that the signal always occupies the same frequency band in the carrier system. The carrier frequency is detected by the circuit of Fig. 3 in which L resonates with C1 at the higher carrier frequency and with C2 at the lower carrier frequency producing a D.C. output at terminal 3 in one case and at terminal 4 in the other. By using a germanium diode for D1 and a silicon diode for D2 it can be arranged that the actuating mechanism connected to terminals 3 and 4 is in the " off " condition, corresponding to the higher carrier frequency transmission, during complete absence of signal. The speech signal is recovered using a square law characteristic diode as a detector.
