Patent ES-8101766-A1 (ES)
Title: Method of making a ribbon cable
IPC: H01B7/08
Filed: 1980-05-30
Abstract: In multi-core electric cable in which the cores extend in side-by-side spaced and parallel relationship, instead of producing the cable with the cores continuously interconnected by surrounding insulation so that when cut into lengths the insulation has to be pulled or cut apart in order to separate the cores for connecting, the cable is made at the outset at intervals along its length with the cores separate, never having been interconnected. This is applicable to most known methods of manufacturing flat multi-core electric cable including those in which each core has an individual insulating sheath interconnected to form the multi-core cable by the bonding of the sheaths together or to backing strip material or to both. In application to multi-core cables made from bare conductors sandwiched between strips of insulating material separation of the cores at intervals is achieved either by omitting at intervals the bonding of the insulating material or by omitting the insulating material at intervals or by a combination of both.

Patent ES-8202211-A1 (ES)
Title: MFB system with a by-pass network.
IPC: H04R3/00
Filed: 1981-03-16
Abstract: A device for driving an electroacoustic transducer (1) comprising a feedback amplifier and a pickup (2) whose output signal is a measure of the acoustic output signal of the transducer. A by-pass network (4) bypasses at least the transducer and the pickup and produces an output signal that for frequencies outside the operating range of the transducer is large and for frequencies in the operating range (f1 to fh) of the transducer is small relative to the pickup output signal. The sum of the output signals of the pickup and the by-pass network serves as a feedback signal. This widens the transducer frequency range and reduces distortion. The device may include a limiter (11) and a network (5) before the transducer. The network has a frequency response inverse to that of the signal path from the electroacoustic transducer to the pickup to provide an additional reduction in the distortion.
