Title: Process of regeneration of recycled solutions used for the production of hydrogen peroxide by means of alkyl-anthraquinones
IPC: C01B15/023
Filed: 1963-07-13
Abstract: Degraded solutions from a cyclic alkylanthraquinone-alkylanthrahydroquinone process for H2O2 production are regenerated by treatment with an oxide of Zn, Pb, Mn or Fe. Treatment may be carried out continuously, say after the steps of oxidation and of extraction of H2O2, on all or part of the decycled solution. The alkyltetrahydroanthraquinone thus obtained may be precipitated at low temperature and oxidized to the corresponding alkylanthraquinone, which may be recycled. Examples are given of regeneration by heating degraded solutions containing Mn2O3, MnO2, MnO, PbO, PbO2, ZnO or Fe2O3 in amounts from 2.5% to 5% under reflux, with bubbling in of argon or air.
Patent ES-307028-A1 (ES)
Title: Improvements in or relating to measuring instruments
IPC: G01B15/02
Filed: 1964-12-12
Abstract: In an instrument for the examination for thickness of components a collimated beam of particle radiation is passed through the component and detected, the resultant signal being analysed by an energy resolution device. The energy of radiation such as [alpha] particles, is reduced in proportion to the thickness of the component that it has passed through. This relation is used in the examination of razor blades e.g. in sharpness measurement. In the described embodiment, a radioactive source of [alpha] particles 6 (Fig. 2, not shown), in the form of PO 210 electrodeposited on to the head 7 of a platinum pin 9, is mounted in a holder 8, having at the end, brass plates 10, 11 separated by aluminium shims 13, 14 and defining a slit of about 1 Á x 1 mm. The detector is a silicon surface barrier detector and is connected to a circuit (Fig. 4, not shown) comprising pre- and main amplifiers 20, 21, a pulse amplitude analyser 22 which can be adjusted to pass only those pulses in a pre-selected energy band, and a scaler 23, to count and display the count digitally. The razor blade 2 (Fig. 1) is mounted on a holder 3 which can be moved on a wedge 4 to various positions with respect to the radiation beam, by a micrometer screw 5. Movement may be continuous or interrupted, using motor drive or hand operation. That part of the beam which reaches the detector directly i.e. which does not pass through the edge of the blade, results in high energy signals, which are suppressed by the analyser 22 if the latter is set to pass pulses of the lower energy ranges corresponding to [alpha] particles passing through the blade. Counts are taken for predetermined times over a series of energy bands with the razor blade at different positions and a profile of the edge of the blade may be obtained in graph form, if desired. Thus with a sharp edge, a slow change in energy reduction is obtained, whereas a blunt blade gives a sudden pronounced value. The analyser may be set to pass one predetermined energy band corresponding to that for radiation passing through the critical region affected by sharpness. Counts are received which then show if blades, passed through the instrument sequentially, are below a predetermined sharpness standard. This enables various applications of the instrument for use in a production line. Other applications are the determination of thickness variations, pin- and blow-hole detection &c. Variable collimation enables average thickness measurements and variation of the instrument's sensitivity. A emitting source maybe used, the detec - tors then being an ionisation chamber or scintillation counter.

Title: Improvements in Wired Broadcasting Systems and Apparatus therefor.
IPC: H04N7/10
Filed: 1967-03-30
Abstract: In a colour television wired distribution system the signal fed to the system comprises a modulated carrier brightness information together with a suppressed carrier colour information signal in respect of two colour information signals and a pilot signal of a frequency equal to the frequency of the suppressed carrier and which is modulated by one colour information component. At the receiver one colour component is derived by envelope detection of the pilot signal and the other by synchronous detection of the colour signal using a reinserted carrier derived from the pilot signal. The transmitter 1 comprises a receiver 16 of broadcast signals of a "PAL" system from which the brightness signal and suppressed carrier colour signals are applied to a modulator 20 to modulate a carrier of about 10.5 Mc/s from oscillator 21. The lower sideband is selected by vestigial sideband filter 23 and applied via mixer 24 to the lines 2 and 3. Colour bursts from the receiver are applied to synchronism oscillator 25 at the frequency of the original suppressed carrier of the colour signal, 4.43 Mc/s, which is modulated by one colour component in modulator 27 before being applied to the lines 2 and 3 via mixer 24. At the receiver 6 the brightness component is selected by filter 31 amplified by amplifier 32 and detected in envelope detector 33, from which the brightness signal is fed out over line 34 while the colour signals modulated on the subcarrier are fed to demodulator 36 via filter 35. The pilot signal, modulated by one colour component, is selected by filter 38 amplified and demodulated at 40 to provide one colour component on line 41, the pilot is also passed through a narrow band filter 44, selecting only the carrier, to provide a carrier for demodulating the other colour component in modulator 36, the phase of the carrier being reversed on alternate lines in phase switch 47, controlled by the colour recognition device 37, to demodulate the appropriate colour component from the colour information sub-carrier wave.

Title: Production of 3-methyl-1-butene
IPC: C07C1/00
Filed: 1967-06-26
Abstract: 3-Methyl-1-butene is prepared by catalytically dimerizing propylene to obtain at least some 4- methyl-2-pentene, which is then contacted with ethylene in the presence of an olefin disproportionation catalyst to produce 3-methyl-1-butene as desired product and propylene, which may be recycled to the dimerization.

Patent ES-346588-A1 (ES)
Title: Network using adaptive elements
IPC: H04Q3/54
Filed: 1967-10-30
Abstract: In a multi-exchange system wherein each exchange is provided with a mimic diagram of the system and a network of order wires links the exchanges, each wire contains a probabilistic gate (e.g. 26 on link 33) which in effect delays the transmission of a path seeking pulse therethrough in dependence on the traffic load on the associated trunks. Whenever an intermediate exchange receives such a pulse on one of its incoming order wires, further pulse reception on any of its incoming order wires is inhibited and the pulse is passed on to its outgoing order wires (the necessary gates are disclosed in Fig. 3, not shown). At the required exchange, reception of the pulse causes a throughpath, comprising relays, to be switched through and lamps on the mimic board at the originating exchange to be illuminated so as to provide a visual display of the chosen route. If a path seeking pulse does not reach the wanted exchange (either at all or within a preset time) the system is reset and another pulse is transmitted. The probabilistic gates (also called adaptive elements) utilize stochastic integrators and are described with reference to Fig. 1, (not shown). The choice of route may be influenced by economic considerations and to allow for this actual delay circuits may be inserted in the order wires. It is suggested that the method of route finding may be used in a computer controlled system.
Patent ES-349461-A1 (ES)
Title: Coil form
IPC: H01F27/02
Filed: 1968-01-18
Abstract: The two coils 43, 44 of a transformer are wound on separate tubular members 11, 17 of resilient material, e.g. polypropelene and the inner of these members 11, is arranged to telescope within the outer member 17, a wedgeshaped projection 30 on the inner member, which projects into window 22 in the outer member, restricting the relative axial and rotational movement of the two members. Fig. 3 is a section taken immediately below projection 30. The portion 31 of the inner member just below the projection 30 is of reduced thickness and channels 32, 33 extend on either side of this portion and of the projection, thus enabling the latter to flex inwardly during the initial assembly of the two members. Axially-extending ridges 38 on the inner members run in corresponding depressions 39 in the outer member, permitting free axial motion but enabling the two members to be temporarily locked together by rotating one with respect to the other so that the ridges and depressions no longer coincide. The projection and ridges 38 may alternatively be on the outer member, with the window and the depressions on the inner member. Further ridges 35 on the inner surfaces of the members grip self-tapping threaded tuning slugs. The coils are wound in moulded spiral grooves (18, Fig. 1, not shown) and moulded projections (19) hold the coil ends, which are connected to terminals 13-16 on base 12. The transformer is enclosed in shield can 41 through which the upper part projects, and portion 20 of the outer member is roughened so that it can be gripped easily during adjustment of its position. The two members may be permanently interlocked by inserting adhesive or bonding material into a small aperture (21) in the outer member, or by passing the tip of a hot soldering iron through both the members.

Title: Arrangement for bringing a rotating system controlled by means of a servosystem into phase and keeping it in phase
IPC: H02P23/18
Filed: 1968-04-24
Abstract: A motor 2 drives an apertured disc 4 cooperating with a lamp 6 and photo-cell 7 to produce a pulse for each revolution of the disc, a train of these pulses forming a control signal 8 representing the speed of the motor. An eddy-current brake 10 is fed through amplifier 11 with a regulating signal 12 derived from a bi-stable multi-vibrator 13 which passes to a first stable state by the control signal 8, and to a second state by pulses of a reference signal 14. When the system is synchronized the two signals have the same frequency, each reference pulse being followed by a control pulse. A short time before a reference pulse is received, stage A of multi-vibrator 23 is blocked, its stage B being conducting. Gate 21 is closed, gate 22 is open, and a monstable multi-vibrator 19 is in its stable state so that gates 17, 18 are open, the multi-vibrator 13 being in its first stable state. When a reference pulse is received, the multivibrator 19 does not change state, and the gates 17, 18, remain open. The reference pulse is passed through gate 17 to the multi-vibrator 13 which passes to its second state. The multivibrator 23 changes state whereby gate 22 is closed and gate 21 is opened. When the next pulse of the signal 8 is received, the multi-vibrator 19 does not change state and the gates 17, 18, remain open. The pulse passes through the gate 18 to the multi-vibrator 13 which passes to its first state, the stage B of the multi-vibrator 23 becoming conductive so that gate 21 is closed and gate 22 is opened. In this manner, the multivibrator 13 delivers the pulse train 12 for controlling the brake. When the system is being started, a number of pulses of the reference signal occur between successive pulses of the signal 8. In these circumstances, the multi-vibrator 13 does not change its state continually but remains in a single state for a period dependent upon the time constant of the multi-vibrator 19. The motor is thus given time to be brought into synchronizm. In another arrangement, the multi-vibrator 23 and the gates are not connected directly to the leads for the reference and control signals, but to the ouputs of the gates 17, 18, Fig. 3 (not shown). In a further embodiment, the multi-vibrators 13, 23, are combined to form a signal bi-stable multivibrator, Fig.4 (not shown).
