Patent ES-433342-A1 (ES)
Title: Isotope separation utilizing zeeman compensated magnetic extraction
IPC: B01D59/34
Filed: 1974-12-26
Abstract: In a system for isotope separation wherein a plasma of ions of one isotope type is created, method and apparatus for magnetically extracting the ions from the plasma without impairing the ionization selectivity and efficiency. In a particle flow of plural isotope types, radiant energy is applied to selectively excite and ionize ions of at least one isotope type without corresponding ionization of particles of other isotope types. A magnetic field is applied to divert the ions of the one isotope type sufficiently to permit separate collection of those ions without the other particle constituents of the flow. The system of the present invention balances the requirements for a high magnetic field to provide sufficient diversion before charge exchange with the requirement for a limited magnetic field to prevent interference with the selective ionization process due to Zeeman broadening of the isotope absorption lines.

Title: Process for the preparation of 2-nitrobenzaldehyde
IPC: C07C201/00
Filed: 1975-03-26
Abstract: 2-NITROBENZALDEHYDE, A VALUABLE CHEMICAL INTERMEDIATE, IS PREPARED THROUGH THE OXIDATION OF AN ALKALI METAL SALT OF 2-NITROPHENYLPYRUVIC ACID WITH POTASSIUM PERMANGANATE IN AN ALKALINE MEDIUM. Advantageously the requisite starting material is prepared directly by the reaction of 2-nitrotoluene and a diester of oxalic acid in the presence of an alcoholate and is then subjected to the oxidation without isolation. In a preferred embodiment the oxidation reaction mixture is acidified to convert the manganese-(IV) oxide to soluble maganese-(II) salts with concurrent conversion of oxalic acid to carbon dioxide. The process is industrially attractive in terms of the high yield, the availability of starting material and the ease of the manipulative steps involved.

Patent ES-8103385-A1 (ES)
Title: Method and apparatus for measuring thermal neutron characteristics
IPC: G01V5/10
Filed: 1979-10-25
Abstract: The thermal neutron decay characteristics of an earth formation are measured by detecting indications of the thermal neutron concentration in the formation during a selected set of two measurement intervals following irradiation of the formation with a burst of fast neutrons. These measurement intervals may consist of a sequence of contiguous, discrete time gates which begins following a discrete time delay after the preceding neutron burst and extends over substantially the remainder of the interval between neutron bursts. The time gates are divided into a number of groups. The durations of the individual discrete time gates within the groups are equal, but the duration of the time gates progressively increases from group to group in the sequence. The duration of the neutron bursts, time delay between the burst and the start of the sequence and of the individual time gates may all be adjusted by a common, selected one of a finite number of scale factor values. The particular set of measurement intervals used is selected from among a number of possible sets as a function of a previously measured value of the decay characteristic. Each measurement interval set is used over only a specific range of decay characteristic values for which it has been determined, in accordance with a previously established relationship between the decay characteristic value and a function of the thermal neutron concentration measurements for the set, to afford enhanced statistical accuracy in the measured value of the decay characteristic.

Title: Shut-off apparatus for pneumatic driven tools
IPC: B25B23/145
Filed: 1980-01-16
Abstract: The improved shut-off apparatus for pneumatically driven tools includes an auxiliary shut-off valve located in the flow passageway. The valve is controlled by a control rod which extends through the air motor into engagement with a latching device. The latching device is held in the latched position with the valve open by a movable weighted control member. The movable weighted control member is responsive to inertia so that as the speed of the air motor decreases due to a torque load imposed thereon, the shaft slows causing the inertial movement of the weighted member to release the latching device permitting the auxiliary shut-off valve to close.

Patent ES-8201070-A1 (ES)
Title: Ribbon feed and lift mechanism for a typewriter
IPC: B41J33/16
Filed: 1980-10-29
Abstract: In a daisy wheel or rotary print wheel typewriter, a single motor is employed to accomplish both ribbon lift and feed for typewriter ribbon and correction ribbon loaded in a cartridge assembly. A single motor drive moves the cartridge assembly support about an axis to present the typewriter ribbon or the correction ribbon to the print point at the print line. When the elevation of the cartridge assembly about the axis is such to permit normal typing upon the typewriter ribbon, only the feed ratchet for the ribbon is engaged. Alternatively, when the rotation is greater, for example, for typing on the correction ribbon, the added elevation of the cartridge assembly effects disengagement of the normal ratchet feed for the typewriter ribbon while allowing advancement of the correction ribbon.

Title: Apparatus for regulating current supplied to a telephone line signal of the type employed in digital telephone systems
IPC: H04M19/00
Filed: 1980-11-28
Abstract: Circuit apparatus for supplying a regulated loop current to a two conductor loop telephone line includes first and second line feed resistances, each having one terminal connected to a respective terminal of the telephone line. A differential amplifier has one input connected to the first resistance and a second input connected to the second resistance in common with the resistance connections to the telephone line terminals. One of the resistances has its other terminal connected to the output of an active circuit means, which circuit operates in a feedback path to supply the desired loop current to the line resistance and therefore the telephone line. The input control signal for the active feedback circuit is derived from summing the output signal from the differential amplifier with a reference signal whose magnitude varies according to the length of the telephone line. The feedback path is supplied by the connection between the output of the active feedback circuit and the line resistance as further coupled to an input of the differential amplifier.
