Patent ES-478723-A1 (ES)
Title: Color television receiver.
IPC: H04N9/64
Filed: 1979-03-16
Abstract: In a receiver subject to SECAM signal reception, an FM detector responsive to the received signals has its center frequency tuning switched between one SECAM subcarrier center frequency and the other SECAM subcarrier center frequency. Control of the switching, in response to line rate, burst interval pulses and to half line rate waves from a triggered flip-flop, is such that tuning is different in image portions of successive line intervals, but the same in lead-in burst portions of successive line intervals. A first sampler effects sampling of the detector output only during alternate burst occurrences, while a second sampler effects sampling of the detector output during the intervening burst occurrences. Sampler outputs are supplied to a comparator which provides an output suitable for controlling disabling/enabling of flip-flop to establish correct phasing of the switching of the detector tuning. Where receiver is a dual standard receiver also subject to PAL signal reception, another output is derived from the comparator for control of the switching of the receiver between PAL-reception SECAM-reception operating modes.

Patent ES-487832-A1 (ES)
Title: Yarn brake for a textile yarn processing machine
IPC: D01H7/86
Filed: 1980-01-18
Abstract: The yarn brake of this invention is useful in a textile yarn processing machine, such as a two-for-one twister, and includes a stationary permanent magnet arranged at one end of a brake housing and spaced from a fixed braking surface in the direction of movement of the yarn.

Other alternatives are described with reference to Figs. 7, 8 and 9 (not shown).
Patent ES-8206667-A1 (ES)
Title: Electrowinning of zinc
IPC: C22B19/00
Filed: 1981-02-18
Abstract: In the process for electrowinning of zinc from acid zinc sulfate electrolyte, electrolyte is recirculated to the cells and a portion of the electrolyte is returned to the leaching operation of zinc-bearing material. By only returning electrolyte that overflows from electrolytic cells that contain new and/or recently cleaned anodes to the leaching operation, the amount of sludge in the cells can be reduced, the period between cleanings of cells can be lengthened and the amount of addition agent for controlling the lead content of deposited zinc can be reduced. Electrolyte overflowing from only those cells that contain new and/or recently cleaned anodes is diverted and kept separate from recirculating electrolyte from all other cells by providing separate means for collecting and transferring electrolyte to the leaching operation. Such means may consist of two separate overflow pipes in the cell overflow means, and shut-off means, whereby electrolyte can be directed either into the recirculation circuit or to the leaching operation, or both, as required.

Title: Corona charging apparatus.
IPC: H01T19/04
Filed: 1982-02-24
Abstract: A corona charging device including a dielectric-coated elongate conductor (11) contacting or closely spaced from a control electrode. In the first version of this device, the control electrode comprises a conductive grid (17), which is mounted against an insulating support (15). In a second version, the control electrode consists of a slotted conductor (94), with the dielectric-coated elongate conductor (11) embedded in the slot (96). A high voltage varying potential (25) between the elongate conductor (11) and control electrode induces a glow discharge in an air region in proximity to the two conductors. The control electrode may act as a grounding member to provide a corona discharge device with respect to a proximate surface (20). Alternatively, the control electrode may be maintained at a desired potential (27) to provide a charging device with an automatically limited voltage. The corona charging devices of the invention are characterized by a linear relationship between output ion currents and a direct current extraction potential. In further versions of the second corona device, the slotted conductor and dielectric-coated conductor may be replaced with alternative structures which provide an equivalent enclosure.
