Title: Pushbutton operated electric contactor - uses spring wire loops shaped to pass round shafts mounted parallel to printed circuit board
IPC: H01H1/24
Filed: 1979-09-01
Abstract: A base-plate (1), such a printed circuit board, carries supports with horizontal shafts (5) and (21). Spring wire (8) is shaped to pass round these shafts, also to form loops (20) and (25), and to provide positive upward pressure on push-button (6). One loop (20) is held in contact with terminal (23) in base-plate.

Patent ES-8103619-A1 (ES)
Title: Voltage-to-frequency-converter
IPC: H02P1/00
Filed: 1980-05-02
Abstract: Voltage-to-frequency-converter, in response to primary variable analog input signal (V<uc>u), generates one or more trains (C F) of output pulses. For each train, its frequency vs. primary input signal characteristic is in three ranges or modes, namely an initial range, in which the characteristic is substantially straight line with positive slope, a second range in which the frequency is constant, and a third range in which the characteristic is substantially straight line with negative slope. Derived from the primary input signal (V<uc>u) are first-range (-i<u1>u) and third-range (-i<u3>u) input signals for an integrator (116) which in their respective ranges subtract from a constant input signal (k). The latter constant input signal (k) is effectively the sole integrator input signal in the second range. A "second" integrator input signal (-i<u2>u) is intermittently injected, subtractively, by the pulses of one output pulse train (C). In consequence, the integrator is saturated in second range, but de-saturated in first and second ranges. A bistable threshold detector (125) is continuously in second state in second range, but switches between first and second states in first and third ranges. Logic and latching circuitry generates the output pulses in response to the detector (125) and clock pulses.

Patent ES-8302563-A1 (ES)
Title: Circuit for monitoring light signal circuits in railway systems
IPC: B61L7/10
Filed: 1982-04-27
Abstract: The subject matter of the invention is a circuit for monitoring light signal circuits in railway systems with the aid of monitor relays which are fed from the light signal circuits which are to be respectively monitored. In comparison with known circuits of this kind which for relatively large light signal distances require special relays with operating and release values which are near to one another, the circuit according to the invention permits the use of simple relays with operating and release values which lie far apart. An increase in the maximum light signal distance in comparison with known circuits is also achieved. To this end, the circuit according to the invention uses switching means which are active in a time-dependent fashion and which ensure that there is an increased magnetic excitation of the monitor relay for a short time after the light signal current is switched on. The excitation reliably causes the monitor relay to operate but does not noticeably effect the light signal.

Title: Serial ink jet printing head.
IPC: B41J2/175
Filed: 1982-12-23
Abstract: The head is provided for a conducting ink and comprises a closed container (14) carrying two electrodes and a nozzle (18). The head is removably mounted on a carriage (13) and is replaced when the ink is exhausted. The container (14) is divided into two cavities (71 and 72) which are in communication by way of an aperture (73, 74, 75) in order to cause ink to flow to the nozzle and to remove bubbles.
