Patent ES-340130-A1 (ES)
Title: Penicillins
IPC: C07D499/00
Filed: 1967-05-03
Abstract: A semi-synthetic penicillin is produced by the acylatiqn of 6 - aminopenicillanic acid adsorbed on an anion exchange resin e.g. Amberlite (Registered Trade Mark) IRA-401. The 6-APA is obtained by the enzymatic hydrolysis of a penicillin such as benzyl penicillin. Preferably the penicillin acylase is derived from a micro-organism resistant to high concentrations of the acyl moiety of the starting penicillin, e.g. phenylacetic acid or phenoxyacetic acid. Thus, in the case of benzylpenicillin, the micro-organism may be a mutant of E. coli Ankerfarm Sp. 27/14 (CBS 128À67) cultured serially on media containing increasing concentrations of phenylacetic acid or phenoxyacetic acid. The hydrolysis of the penicillin may be carried out with cultures or enzyme extracts of the micro-organisms. After hydrolysis, impurities may be removed by extraction with a water-immiscible solvent, e.g. ether, and the aqueous phase containing the 6- APA treated with the resin at pH 6À0. The 6-APA resinate is separated from the solvent, washed to remove impurities and then suspended in water of pH 7 to 9 containing sodium chloride. The acylating agent is used as the chloride or anhydride, which is dissolved in a watermiscible solvent such as acetone and added to the aqueous suspension of 6-APA resinate at e.g. 0 C. After acidifying to e.g. pH 2À0, the result ant penicillin may be extracted with a waterimmiscible solvent e.g. ethyl acetate. The penicillin may be recovered as a salt by extracting the organic solution thereof with an aqueous solution of a base, e.g. sodium bicarbonate solution.

Title: Device for transmitting an accurately determined fixed frequency with a tunable high frequency transmitter tube
IPC: H03L7/04
Filed: 1968-06-11
Abstract: In a tuning arrangement for an oscillator providing a predetermined fixed frequency comprising a rotor 2 rotatably supported in a stator portion and driven by a reversible motor 1, the rotor is rotated in a certain direction to continuously vary the tuning frequency of the oscillator and an arrestor arrangement is provided which is rendered ineffective when the tuning body is rotated to provide the continuously varying tuning frequency but which functions when the rotor is rotated in the opposite direction by the motor so as to arrest the rotor in a position which corresponds to the predetermined oscillator frequency. The rotor shaft 2 of the motor 1 of a tunable magnetron, is attached to a disc 3 such that when the disc is rotated clockwise, the tuning of the magnetron is continuously varied and a catch lever 7 is moved by springs 14, 15, which are in frictional contact with the disc 3, against a stop 12. If the direction of the motor is reversed the disc 3 moves anticlockwise until the lever 7 moves against a projection 4 and the tuning of the magnetron is then fixed. The pre-set frequency may be varied by rotating a shaft 18 and screw 16 which meshes with teeth or a rack 17 on the ring 9, on which the catch lever 7 is mounted. The locking and adjusting arrangements are protected by a lid 23 which is hermetically connected to the arrangement. The motor may be of two-phase type connected to provide forward and reverse under control of a switch (27, Fig. 3, not shown). Automatic frequency control (Fig. 4).-The output from the magnetron is passed to the aerial via a waveguide 28 which is coupled via a directional coupler 29 to a further waveguide 30. Two cavity resonators 31, 32 tuned to different frequencies are coupled to the waveguide 30 and feed detectors 35, 36 which give outputs in opposite directions. The outputs from the detectors are added in an amplifier 37 which gives an output error voltage. This is fed via a peak rectifier 39 to control a servomotor 40 which is coupled to the shaft 18 of the tuning arrangement so as to maintain the predetermined frequency half way between the frequencies (f 1 , f 2 , Fig. 5, not shown), of the cavity resonators 31, 32. An attenuator 38 may be provided so that the output voltage from the detectors can be adjusted to be equal.

Title: Circular knitting machines
IPC: D04B15/68
Filed: 1968-07-20
Abstract: Following the raising of those selector instruments 4 by cams P1 . . . P6, one at each station, due to their remaining in a position projecting from their tricks after selection by selector cams SC, the selectors which have been depressed within their tricks by the selector cams SC are immediately reprojected prior to the raised selectors being returned to their original low level. Consequently the raised selectors on return to their original low level as well as the other selectors are in a projected position ready for immediate reselection by a further bank of selector cams at the next station. Selection between stations can be achieved over a shorter distance whereby more space, is available around the machine. The invention is described in connection with a six feeder machine in which pivotal selectors 4 having frangible butts are selectivelyactuated by selector cams SC. To enable the lower ends of those selectors which have been depressed to miss the raising cam to be projected outwardly the following portion of each cam P1 . . . P6 is recessed or relieved as at 8.

Patent ES-420377-A1 (ES)
Title: Variable transmission time delay compensation arrangement
IPC: H04B7/005
Filed: 1973-11-08
Abstract: This arrangement includes a variable delay circuit through which a color television signal is propagated prior to transmission to a communication satellite. The television signal is received from the satellite at the transmitting station. The color subcarrier is extracted from the received television signal and also from the original television signal. Both of the extracted color subcarriers are translated to the same frequency disposed above the frequency of the television signal. The translated subcarrier extracted from the received television signal is propagated through the delay circuit with the original television signal. At the output of the delay circuit this latter subcarrier is extracted and applied to a phase comparator for comparison with the translated subcarrier extracted from the original television signal. A control signal is produced proportional to the phase difference between the two compared translated subcarriers. The control signal controls the delay of the delay circuit to maintain the compared translated subcarriers in a predetermined phase relationship to compensate for variable transmission time delay to the satellite.

Filed: 1974-10-14
Abstract: A straightening machine for long tubular or bar-shaped round workpieces has a row of straightening units into which a fresh workpiece is introduced and from which a straightened workpiece is removed by moving sideways. Each unit has two lower straightening rolls and an upper straightening roll movable between an extended position in which it cooperates with the other rolls of the same unit to straighten a workpiece and a retracted position in which a fresh workpiece can be inserted or a treated workpiece removed. All upper rolls are movable in a synchronism with each other in response to rotation of a crankshaft which is mounted in the frame of the machine and transmits motion to the upper rolls through the medium of double cranks and connecting rods. The crankshaft is rotatable by a drive which has a gear secured to an intermediate portion of the crankshaft and a fluid-operated motor or a set of pulleys for rotating the gear through the medium of one or more additional gears. The crankshaft further serves to raise and lower the upper sections of tubular guides in which the workpiece is confined between neighboring straightening units during treatment by the rolls. The upper sections are lifted simultaneously with the upper rolls to allow for unimpeded insertion of fresh workpieces and removal of straightened workpieces. A further shaft can adjust the positions of upper rolls independently of the crankshaft so that the units can receive workpieces having larger or smaller diameters.
