Patent ES-385955-A1 (ES)
Title: Phosphates
IPC: C03C13/00
Filed: 1970-11-27
Abstract: Complex phosphates of aluminum containing a halogen and chemically-bound molecule of a hydroxy compound, which may be water or an organic hydroxy compound. A typical example is a complex phosphate containing ethyl alcohol having the empirical formula AlPClH25C8O8. They are most conveniently prepared by the reaction of an aluminum halide with the appropriate hydroxy compound and orthophosphoric acid, under relatively cool conditions. The compounds are generally soluble in water and polar organic solvents. They decompose at low temperatures to give aluminum orthophosphate, thereby providing a method for producing aluminum phosphate in many forms, for example, fibers, coatings, binders and fine particles, from a solution in water or organic solvents.

Patent ES-413570-A1 (ES)
Title: Method and apparatus for preparing the ends of cables for splicing
IPC: H02G1/12
Filed: 1973-04-11
Abstract: To prepare a multi-conductor jacketed cable for splicing it is necessary to remove the jacket for some distance from the end of the cable and to cut the conductors so that they extend for different distances from the end of the jacket. This is done by first gripping the cable by a clamp some distance from its end. Longitudinally spaced pairs of cutters are then brought together to cut through the conductors and through the jacket to the conductors with the cut through the conductors being spaced toward the clamp from the end of the cable a greater distance than the cut through the conductors. The clamp is then moved away from the cutters so as to pull the main portion of the cable with it while leaving the portions of the jacket and conductors between the cutters and the end of the cable behind.

These data words are analyzed by the computer to determine the operability of the equipment. Signals indicative of the condition of the equipment are sent from the computer system to the remote facility. All the data transmitted via the telephone network is checked for accuracy by retransmitting the data to the point of origin and comparing it, bit by bit, to the data as transmitted. Any data found to contain errors is retransmitted.
Patent ES-418581-A1 (ES)
Title: Television deflection circuit having horizontal pincushion correction
IPC: H04N3/237
Filed: 1973-09-08
Abstract: A deflection circuit for a television receiver having a vertical final stage powered by a horizontal final stage. A supply circuit containing rectifiers and filters is disposed between the horizontal and vertical stages for rectifying and filtering the horizontal-frequency a.c. voltage. The filter of the supply circuit is designed to oscillate at the frequency of the vertical deflection current and thereby directly modulate the current flowing in the horizontal deflection circuit to provide horizontal pincushion correction. Pincushion correction is enhanced by connecting a pair of RC circuits in parallel with the vertical deflection coils, each RC circuit includes a diode so that one RC circuit conducts in one direction at the beginning of each vertical deflection period, and the other RC circuit conducts in the opposite direction at the end of each vertical deflection period so as to generate a sawtooth current which is superimposed on the current drawn from the horizontal final stage.

Title: Treating apparatus for animal hide and like
IPC: C14C15/00
Filed: 1975-04-17
Abstract: Rotating drum, mounted on a horizontal shaft, has a charging and discharging orifice opposite the driving end with its pulley and motor. An endless screw, coaxial with the drum, transports the skins and prods. from the opening into the drum, when the latter is rotating in one direction and discharges them when it turns in the opposite direction. The endless screw moves the skins in a progressive manner which can be controlled by altering the rotational speed of the drum. The shaft of the screw may be hollow so that liqs. can be introduced inside the drum. Introduction of the skins is facilitated when the drum turns in the working direction and the treated skins can be discharged, automatically and at a controlled rate, merely by reversing the direction of rotation.

Patent ES-442431-A1 (ES)
Title: Apparatus for electrically converting an analog signal into a digital representation
IPC: G06F17/40
Filed: 1975-11-07
Abstract: A method is described for electrically converting an analog signal into a digital representation in a manner that maximizes noise rejection. The digital representation is formed from a preselected number of discrete points corresponding to sampled approximations of the analog signal. In establishing the magnitudes of the respective points, digital samples of the analog signal are taken at a predetermined number of discrete coordinates along the analog signal on either side of the respective discrete points. The predetermined number of coordinates are averaged and employed as corresponding approximations for the respective discrete points in the digital representative reproduction of the analog signal. The effects of harmonics of power line frequencies associated with processing electrical equipment are minimized by sampling the discrete coordinates for a particular point over an integral number of cycles of the power line frequency. In addition, noise having a high frequency, low duty cycle can be minimized by sampling a relatively large number of discrete coordinates over a period substantially greater than the occurrence of the noise.

Title: An instrument for placing material into both canals of the fallopian tubes.
IPC: A61F2/958
Filed: 1978-11-07
Abstract: A fluid dispensing instrument and method for placing a drug material into the canals of the Fallopian tubes of a female. The instrument has a housing carrying a piston and cylinder assembly. An elongated flexible tubular probe attached to the housing carries an expandable sleeve. The piston and cylinder assembly is operable to fully collapse the sleeve prior to insertion through the cervical opening into the uterine cavity. After the sleeve is inserted into the uterine cavity, an ampulla storing the drug material is loaded into the instrument. The piston and cylinder assembly is then actuated to initially partially expand the sleeve. Operation of the piston and cylinder assembly moves a plunger into the ampulla to dispense the drug material into the uterine cavity above the partly expanded balloon. The sleeve is then fully expanded to move the drug material from the uterine cavity into the canals of the Fallopian tubes.
