Patent ES-343678-A1 (ES)
Title: Through-connectors for circuit boards and method of applying same
IPC: H01R12/51
Filed: 1967-07-17
Abstract: The plug 24 supporting the flexible conductor 22 connecting the circuit elements 14 on either side of a printed-circuit board 10, as described in Specification 1,086,093, is made of a plastics material exhibiting the property of plastic memory, such as a polyolefin or polyethylene. Prior to its insertion in the aperture 16 in the printed-circuit board the plug has its diameter reduced by irradiating or heating and stretching it longitudinally and then freezing it. After insertion heat is applied to increase the diameter of the plug again and thus urge the conductor against the inner surface of the aperture so as to fill it completely. The conductor 22 is then connected to elements 14 by means of solder 28. Instead of a conductive braid a sinuous or helically wound conductor can be employed.

Title: Improvements in Transfer Stations for Regulating Industrial Units
IPC: G05B15/02
Filed: 1968-02-09
Abstract: In a control system for an industrial process of the type comprising a plurality of regulators each controlling a respective variable of the process under the supervision of a digital computer which is connected to the regulators in a numerical multiplex manner, Fig. 4 (not shown), a respective transfer station 3 is provided for the regulation of each variable and comprises a first regulating loop including the computer 2 and a storage circuit 31 and a second regulating loop K1, 33 with proportional action which produces a signal V to control the variable of the process 4. The computer 2 is fed with a set-point signal Co representative of the desired value of the variable, with a signal M representative of the measured value of the variable and with the co-efficient K2 of integral action which is related to the coefficient K1 of proportional action of the second regulating loop. The computer is programmed to produce at fixed sampling intervals of time, a signal U which relates the parameters Co, K2 and the sum of the regulation deviations preceding the considered sampling interval, the last mention mentioned parameter being derived from the signals Co and M applied to the computer. The analogue signal U is memorized in the storage circuit 31 under the control of selection pulses S controlling the multiplexing of the different stations connected to the computer. The circuit 31 derives a modified set point signal Cm which is similar to the signal U and is applied to a comparator 32 for comparison therein with the signal M, the error signals so produced being applied to the amplifier K1 whose gain corresponds to the co-efficient Kl. Member 33 is a function switch providing for change over from automatic to manual control. The modified signal Cm is such as to compensate for the static deviation of the second regulating loop. The circuit for obtaining the signals U and Cm is described, Fig. 2 (not shown) and comprises basically a series combination of a comparator, a sampler, an amplifier and an integrator whose output feeds the storage circuit 31 through a further comparator. The circuit 31 comprises a relay controlled by the pulses S and an operational amplifier shunted by a capacitor, Fig. 5 (not shown). Should the station 3 become isolated from the computer, proportional regulation is retained at the setpoint value existing immediately prior to isolation. The operation of the second regulating loop during such isolation is discussed. Fig. 3 (not shown).

Patent ES-429450-A1 (ES)
Title: Film projector and cartridge apparatus
IPC: G03B31/02
Filed: 1974-08-22
Abstract: A cartridge loaded film projector includes film driving and sound pickup components and apparatus for automatically engaging and positioning the film with respect to these components when a cartridge is inserted into the projector. A pressure roller and pressure pad are mounted within the projector on a pivotably mounted frame. The frame is normally biased out of the cartridge's path within the projector but an actuating arm attached to the frame extends into the path. When a cartridge is inserted along the path, it engages the arm and thereby pivots the frame and thus the roller and pad to engage the film and position it against the projector's film driving and sound pickup components. The cartridge holds the frame in position while inserted, but the frame automatically returns the roller and pad to inoperable positions upon cartridge removal. The projector and all cartridges are constructed so that the cartridges may be varied in size.
Patent ES-431289-A1 (ES)
Title: Switchable video amplifier
IPC: H04N7/12
Filed: 1974-10-23
Abstract: A video frequency amplifier is biased to provide output signals of a first magnitude. In response to the application of a predetermined control signal, the bias is altered so that output signals are provided of a second, different magnitude. When employed in communications systems of the type in which television images are "frozen" by a storage tube for subsequent transmission on an individual frame basis by a voice-quality telephone link, for example, and subsequently re-created, the control signal indicates whether the system and its storage tube are to operate either in the "transmit" or "receive" mode. Power dissipation is kept low by energizing the amplifier only during those times when input signals are applied for amplification.

Title: Press for record and central title label - uses galvanic deposition of impressed mould on nonconductive support
IPC: G11B23/40
Filed: 1977-07-07
Abstract: The process is for producing a record with a central label in a press. It uses a mould constructed by a galvanic metal deposition on a non-conductive support. The latter is previously engraved with a spiral track and the musical recording track is cut in the surface of the mould element. There is a central depression in the non-conductive support, before the deposition of the mould, which is used to stamp one face of the required record. The central depression formed in the non-conductive support is provided by a photosensitive layer, subsequently exposed to a film carrying the required text, used as a mask for engraving the text in the surface of the support. The impression is thus transferred to the mould and then to the record.

Title: Sun-tracking solar energy conversion system
IPC: F24S50/20
Filed: 1977-07-15
Abstract: A number of solar energy converter assemblies are carried by a support frame which is mounted for independent rotation about a horizontal and a vertical axis. Sensors detect the position of the sun and control circuitry positions the support frame in elevation and azimuth so that the converter assemblies track and face the sun whenever the sun incident energy is greater than a threshold level of about 25 percent of normal. Each converter assembly includes a solar cell and a multiangular conical concentrator shell for collecting, concentrating and directing incident solar energy onto the solar cell. The converter assemblies, the support frame and its mount, and the drive mechanism for the support frame are all located within a transparent stationary housing or enclosure, which provides complete environmental protection for all elements mounted within the enclosure.
