Title: New n-heterocyclic compounds
Filed: 1959-12-05
Abstract: The invention comprises 3-substituted 10.11dihydro-5H-dibenzo[b.f]azepine, and 3-substituted 5H-dibenzo[b.f]azepines of general formula <PICT:0914717/IV (b)/1> where X represents the ethylene or vinylene group and Y, chlorine or bromine which are prepared by reacting a 5-acyl iminodibenzyl in the presence of a Friedel Crafts condensing agent, with an acetyl halide or acetanhydride, converting the resulting 3-acetyl-5-acyl by hydrazoic acid into a 3-acetamido-5-acyl imino-dibenzyl, partially hydrolysing to 3-amino-5-acyl imino-dibenzyl converting into a diazonium salt, reacting with cuprous halide and hydrolysing the product to the dihydro azepine, and halogenating, reacting the 3-substituted 5-acyl-10-halogen iminodibenzyl to split off hydrogen halide and hydrolysing the 3-substituted 5-acyl iminostilbene to the 3-substituted-5H-dibenzo azepine where X is the vinylene group. The reaction product of the 3-amino-5-iminodibenzyl diazonium salt with cuprous halide according to Sandmeyer, may be treated with N-bromosuccinimide or with 1.3-dibromo-5.5-dimethyl hydantion, N-chlorosuccinimide, N-bromophthalimide, or Nbromoacetamide to form a 3-substituted 5-acyl-10-halogen iminodibenzyl. The splitting of the hydrogen halide and the hydrolysis stages may be performed concurrently. An alternative process for the preparation is by the hydrogenation of 3.7-dihaloiminodibenzyl in the presence of a catalyst such as Raney nickel, or noble metals, and an inorganic or organic base in solvents such as methanol, ethanol, methoxyethanol and dioxane. The compounds may be used as intermediates in the production of compounds substituted in the imino group having therapeutic properties. Specification 777,546 is referred to.

Patent ES-319243-A1 (ES)
Title: Improvements relating to telephone dialling apparatus
IPC: H04M1/272
Filed: 1965-11-04
Abstract: Digits of a telephone number are successively keyed into storage locations of a mechanical store which is read upon command to effect transmission of digital impulses to line as many times as desired. The store may eventually be cleared either upon command or automatically upon replacing the hand set at the end of a call. The keys, which are shown in Fig. 1 as two rows of five although one row of ten or three rows of three plus one key may be used, engage when depressed, a corresponding one of a row of spring biased plungers PL which depress a particular one of ten storage buttons PO in one row of ten rows of such buttons arranged around a cylinder CP. Successive operation of the keys brings successive rows of buttons into alignment with the plungers. To ensure that only one key can be depressed at a time, a depressed key must push its way through a row of beads BL whose spacing allows only one key to enter. The storage buttons comprise a split pin having a bulge in each half which co-operate with one of two sets of hollows in the cylinder wall depending on whether the button is depressed or not. When all the digits have been stored, impulse transmission is started by key T1, whose effect may be made conditional upon either the removal of the handset or receipt of dialling tone, and the cylinder rotates to a position to bring the first row of buttons into correspondence with a row of pairs of spring contacts (not shown), one of which is operated according to the button depressed thence digit stored. An unspecified device is thereby operated to transmit the required number of impulses to line, after which it controls an escapement mechanism to present the next row of buttons to the spring contacts. At the end of transmission the cylinder is automatically returned to its home position from where is is either driven forward again in response to key T for a further reading of the store or the store is cleared either in response to key T1 or automatically on replacing the handset by means of an arcuate corrugated plate VG being moved rightwards by electromagnet EM to push all the depressed buttons upwards. Key T1 may be operated whilst the digits are being inserted if a mistake has been made, whereupon the cylinder is rotated to its home position for clearing. A device is described for attachment to a telephone dial in which a plate carrying a series of plungers initiates manual dialling by inserting a particular one of the plungers into a finger hold and rotating the plate in response to the closing of a particular pair of read-out spring contacts. The keys may additionally produce a temporary or permanent record of the telephone number: which record may also contain the date and duration of the call.

Patent ES-355992-A1 (ES)
Title: Method of preparing cyclohexane from toluene
IPC: C07C13/18
Filed: 1968-07-10
Abstract: Cyclohexane is prepared by thermally hydrodealkylating toluene to benzene and catalytically hydrogenating the total dealkylation effluent in admixture with additional hydrogen. Hydrogen for both steps is suitably from a single source, to which unused hydrogen is recycled. Suitable hydrogenation catalysts are Ni/Al 2 O 3 and Pt/Al 2 O 3 , and the hydrogenation is preferably carried out as follows: the dealkylation effluent is split into 3 streams, the first of which enters the top of a first hydrogenation reactor, the second of which enters the middle of said first reactor, and the third of which by-passes the first reactor and joins the effluent from the first reactor, said combined streams then being passed through a second hydrogenation reactor. Any methylcyclohexane-inthe final product may be dehydrogenated to toluene and recycled.
Patent ES-359338-A1 (ES)
Title: Automatic steering control system
IPC: G05D1/02
Filed: 1968-10-19
Abstract: A relay-actuated reversible automatic steering motor is controlled by a differential amplifier to one input of which is applied a potentiometerderived voltage proportional to course error and to the other input of which is applied the combined outputs of a follow-up potentiometer and a helmoperated potentiometer connected in parallel and supplied through equal series resistors. In a system for steering a ship, Fig.2 a gyro-compass repeater adjusts a potentiometer 17 on deviation from a set course so that a direct voltage change is applied through a low-pass filter circuit F 1 , a transistor impedance matching circuit S 2 , and a high-pass filter circuit F 2 , to a biased differential transistor amplifier 40 so that if the deviation exceeds a predetermined value in either sense, a relay RB or RT is energized to operate areversible steering motor in the appropriate sense to correct the deviation. The filter circuits F 1 and F 2 are adjustable to permit a critically damped response to be obtained for any given loading of the ship. The output of a follow-up potentiometer 13 operated by the steering is applied as negative feedback through a further transistor impedance matching circuit S 1 to the other input of differential amplifier 40. The output of a potentiometer 23 connected in parallel with potentiometer 13 is added to the feedback voltage, and potentiometer 23 is adjusted to cancel the effect of any offset of the steering, to counter crosswind for example, when on the desired course. Initial setting of potentiometer 23 is facilitated by setting switches 11 to position V to disconnect the course deviation signal and the relay control circuits. The proportional band may be set by adjustable resistors Q 1 , Q 2 in series with potentiometers 13, 23. Course deviation signals are limited in each sense by a circuit 30 biased by the voltages from potentiometers 26, 27 also supplied in series with resistors Q 1 , Q 2 . Operation of switches 11 to position M replaces the course deviation signal by a fixed voltage from a potentiometer 66, 67 and permits manual control of steering by potentiometer 23 or another potentiometer substituted for it.
