Title: Method and a device for generating an equal-tempered tone scale in musical instruments
IPC: G10H5/08
Filed: 1967-06-28
Abstract: A device for generating a tempered twelvetone scale in electronic musical instruments comprises twelve oscillators, each generating a tone in the octave, the frequencies of three tones satisfying the equations f n-2 - f n-3 = f n /20 = f n-12 /10, in which n is the ordinal number of the tone in the scale, one oscillator frequency being adjusted independently and the other frequencies being controlled by signals derived from two of the other oscillators. As shown in Fig. 1, each oscillator consists of a Schmitt trigger ST, with feedback via R 1 , R 2 , R 3 , C 1 , controlling the period of the rectangular output, and a bi-stable flip-flop FF 1 , producing the basic frequency f n which is divided by two at each of the flip-flops FF 2 , FF 3 , and by five by the divider Sc 5 , to give a tone of frequency f n /20. Output signals from B n and C n of FF 2 , FF 3 respectively generate tones of frequencies f n /2, f n /4 in adjacent lower octaves. The frequency fn/20 is compared with frequencies f n-3 , f n-2 in an AND-gate consisting of diodes D 1 , D 2 , D 3 , D 4 , the current produced by this coincidence unit being integrated in a capacitor C 2 , which delivers a control voltage to an output terminal D n , this control voltage being used to regulate one of the input frequencies to the coincidence unit. The basic frequency setting of each oscillator may be changed by a stabilized voltage V +, and an individually set potentiometer P in each oscillator compensates for variations in the effect of V + . The coincidence unit may be replaced by a phase-sensitive detector. The oscillators may be crystal controlled, and the synchronization method can be applied to a mechanical system. Frequency multiplication may be used instead of frequency division.

Title: Improved Method of Producing Copper Wire
IPC: C25D1/04
Filed: 1968-10-02
Abstract: Copper rod for drawing down into wire is produced by continuously forming at least one elongated member, e.g. a single sheet 7 to be subsequently cut into a number of strips 15 by cutting rollers 14, a single strip or a plurality of separate strips, by electro-deposition on a cathode surface, e.g. formed by or carried on a rotating steel drum 3 or continuously moving belt, moving through a bath of electrolyte 2 adjacent to an anode or anodes 5 of partially refined (e.g. blister and/or scrap) copper, and continuously stripping the member from the cathode surface and passing it through the same or a different electrolyte bath adjacent to further anodes 10 of partially refined copper to build up its thickness to that required for drawing down. Preferably, the stripped member passes in a zig-zag path vertically downwards and upwards between each successive pair of a series of spaced vertical elongated anodes 10. Cutting into strips 15 may be effected as the sheet 7 passes from one part of the bath to another, or from one bath to another, or as it leaves the single or final bath. The knife edges of the cutting rollers 14 may be inclined to form strips 15 of hexagonal or near circular cross-section. At one or more intermediate stages, the member may pass out of the bath through an induction annealing chamber 12. The electrolyte may be introduced under pressure through a pipe 6 into the space 4 between the cathode surface and its associated anode (s) 5 in a direction opposite to that in which the surface is moving, e.g. drum 3 is rotated, to remove sludge. Forced circulation of electrolyte in the or each bath may also be effected. Some or all of the anodes 5, 10 may be in the form of perforated Ti containers filled with pieces of scrap copper, the containers preferably being surrounded by a porous covering of polyethylene, polypropylene or PVC. The Ti container may be annular to allow passage therethrough of a strip (Fig.4). Scrap copper may be replenished continuously during the process. The copper may be deposited on moving strips in such a way to build them up into a shape approximating to circular cross-section, by projecting the electrolyte preferentially on to selected parts of the moving strips, suitably shaping the effective surfaces of the further anodes, or by axially twisting the strips as they pass between the further anodes. Alternatively, two or more strips may be bonded together to form a rod by passing between pressure rolls or through a die.

Patent ES-395779-A1 (ES)
Title: Device for the treatment of ferrous metal ingots which are intended to be removed from molds without hold-up periods
IPC: B22D7/10
Filed: 1971-10-06
Abstract: The device is constituted by a heat-insulating and/or exothermic lining, comprising a single element or a number of juxtaposed elements, provided with a metallic reinforcement which has an extensive open structure and forms meshes. One portion of the meshes is embedded in the thickness of the lining, whilst another portion, adjacent to the volume which is filled with molten metal, is uncovered. Since the contact surfaces between the mold and the metallic portions which serve to clamp the lining to the mold are quite small, the transmission of heat from the metal to the upper portion of the mold is greatly reduced with respect to known devices. Moreover the manufacture of each element only requires placing the corresponding portion of the reinforcement in a mold with permeable walls, wherein a slurry is fed and the bonds between the lining, the reinforcement and the ingot are improved, which allows early displacement of the ingot after its removal from the mold.

Title: Hydrostatic shaft seal
IPC: F16J15/40
Filed: 1972-01-25
Abstract: A hydrostatic shaft seal for a rotatable shaft extending through an opening in a housing includes a seal ring substantially enclosed in a stationary seal ring casing consisting of seat plates. The seat plates are positioned in the housing opening with operating choke gaps formed between opposite axial end surfaces of the seal ring and the adjacent portions of the seat plates. One of these gaps is in communication with a space containing hydraulic fluid under operating pressure, and the other gap is in communication with a space at a relatively lower pressure. The two gaps are connected in series to open and close in opposition. Elastic seal elements are provided between the seal ring and the shaft to provide for relative axial displacement of the seal ring under the oppositely acting hydraulic pressures. The seal ring can be a single element or a two part element, and the hydrostatic shaft seal can be designed for feeding hydraulic fluid at operating pressure from the housing to the shaft, with the space under operating hydraulic pressure being in communication with the shaft and the housing through pressure medium lines. A cap is located within the opening in the housing and covers one of the sides of the seat plates which side extends transversely of the shaft. Elastic seal elements are provided between the cap and the juxtaposed surfaces of the seal plate and the combination of the elastic seals, the cap and the seal plate form at least one compensation space. A bore or passage through the shaft seal connects the compensation space with the hydraulic pressure medium so that the force provided by the pressure of the hydraulic pressure medium in the compensation space opposes the deformation forces provided by the hydraulic operating pressure.

Title: Serially operated comparison system with discontinuance of comparison on first mismatch
IPC: H04W88/02
Filed: 1974-11-04
Abstract: The components of a message signal to be identified are serially fed to a comparator which compares them, one at a time, with like-ranking components of a reference signal registered in a display unit. Upon detecting a match between the first components of the two signals, the comparator steps a counter to call out from the display unit the second component of the reference signal for comparison with that of the incoming message signal, and so forth. In the event of a mismatch, the counter is reset if all components match, an output signal is given. If the signals are in binary code, the comparator is a logic circuit if they are composed of a series of different frequencies, the comparator is a mixer.

Patent ES-435653-A1 (ES)
Title: Information transmission system
IPC: G11B20/24
Filed: 1975-03-15
Abstract: The influence of disturbances such as tape noise, distortions or dropouts is to be drastically suppressed. For this purpose, an information signal and a compensation signal are read out from a recording medium. The compensation signal corresponds to the unwanted signal which has entered the information signal during its recording. The information signal and the compensation signal are contained in recording channels (S1, S2). The channels S1, S2 may be contained in separate tracks or as separate frequency bands in one track. During the recording, the input signal is recorded in the first channel (S1). The recorded signal is read out and is fed with the input signal, time-delayed in the time-delay element T, to a comparator device (A). The output signal of the comparator device reproduces the error in the recorded signal it is recorded in amplified form in the second track (S2) as a compensation signal. During reproduction, the information signal of the first track (S1) and the compensation signal of the second track (S2) are fed to an adding circuit (C). The output signal of the adding circuit (C) is free from the above-mentioned disturbances.

Patent ES-441261-A1 (ES)
Title: Digital communications system with immunity to frequency selective fading
IPC: H04B7/22
Filed: 1975-09-25
Abstract: A digital communications system with increased resistance to frequency selective fading. Digital signals to be transmitted are phase shift modulated upon a spectrum spreaded carrier. The carrier is generated by mixing the output of a band spread oscillator with a locally generated IF oscillator signal. The signal thus obtained is divided into transmission periods, each of which is longer than the maximum spreading time of the nonlinear transmission medium. The increased bandwidth occupancy thus obtained increases the immunity of the transmitted signals to frequency selective fades moving across the allocated bandwidth. The signals are received by a differentially adaptive receiver which automatically adjusts its response to the envelope of received signals.

Title: Concrete building facade slab shuttering - has one piece internal and external panels with former withdrawn through slot in roof slab
IPC: E04G11/10
Filed: 1978-09-19
Abstract: The shuttering system for buildings of reinforced concrete slab construction, and suitable for facade panels uses one piece internal (5) and external (4) shutter panels in association with a head coupling (7), using a longitudinal slot (12) in the edge of the upper slab (2) to extract the internal shutter (5). The two panels (4, 5) are cross-tied (13), and the system requires that all slabs (1, 2, 14) except the facade of a building cell have been cast previously. The shutter is erected with the internal panel (5) supported by the floor (1) beneath, and the external shutter (4) suspended from a cantilever assembly (18, 19) from the floor (2) above. Once the ties (13) are installed, the concrete is poured. The overhead coupling (7) permits striking of the external shutter (4) by pivoting, and permits attachment to the internal shutter (5) for a straightforward vertical withdrawal. When the shutters are struck and lifted away, the slot (12) in the upper floor (2) is filled with concrete and the cycle repeats.
