Patent ES-483265-A1 (ES)
Title: Polarized electrical connector
IPC: H01R13/639
Filed: 1979-08-09
Abstract: A permanent or detachable assembly to pull an electrical plug and receptacle into a mated position including, for example, preferably two jackscrews positioned through flanges on the plug and receptacle at opposite ends thereof, the jackscrews having surrounding keying devices which prevent plug and receptacle mating if not aligned. For example, the keying devices may be mounted to corresponding flanges in one of six positions. This makes it possible to allow one and only one plug out of six to mate with a corresponding receptacle. Thus, a wrong connection between a plug and a receptacle is impossible when no more than six types of connections are provided. However, other connections and/or positions are possible.

Patent ES-8100181-A1 (ES)
Title: Vehicle load sensing arrangement
IPC: B60T8/26
Filed: 1980-01-16
Abstract: A vehicle load sensing arrangement comprises an input arrangement to which is applied the force of a road spring and a control valve which may, for example, be a pressure reducing valve, having a movable valve member. A control spring acts in opposition to the road spring and together with a force-reduction arrangement serves to reduce the road spring force so that only a proportion of the road spring force is applied to the valve member the remainder being applied to the sprung part of the vehicle. To reduce the load and size of the control spring, and to thereby reduce the required installation space, the control spring is arranged between the valve member and the force-reduction arrangement and acts against the force transmitted by the force-reduction arrangement, so that the effective force acting on the valve member is the difference between the proportion of the road spring force transmitted by the force-reduction arrangement and the force of the control spring.

Patent ES-8404586-A1 (ES)
Title: Flash A/D converter having reduced input loading
IPC: H03M1/36
Filed: 1983-05-17
Abstract: A flash analog-to-digital converter includes 2N comparator circuits for an N bit resolution. Each comparator comprises a summing capacitor which is alternately connected to a reference ladder and to the input signal. The majority of the capacitors are substantially charged and discharged between input potential and reference potential each cycle. The charging/discharging tends to load both the reference ladder and the input signal source. The loading is reduced by including a D.C. biased FET between the input signal source and each summing capacitor. The FET's are biased to condition them to operate as source-followers with the summing capacitors as the load element for at least a portion of the input signal range. Respective ones of the summing capacitors are thereby precluded from charging/discharging over the full input signal excursion which in turn reduces loading on associated circuitry.
