Patent ES-410944-A1 (ES)
Title: Antiskid braking system
IPC: B60T8/60
Filed: 1973-01-25
Abstract: In an input control unit for a vehicle anti-skid braking system, a wheel-speed sensor delivers speed signals to the first input of a differential amplifier. Simultaneously, a capacitor is charged through a resistor and a diode. The capacitor is discharged at a constant rate into a device connected to the second input of the differential amplifier. Another diode prevents the voltage across the capacitor from becoming higher than the voltage of the speed signals. The braking pressure is released for the duration of output signals produced by the differential amplifier. The duration of these signals is kept within safe limits due to the fact that the additional diode limits the voltage across the capacitor.

Title: Horizontal crossbar multiswitch control device
IPC: H01H67/26
Filed: 1974-10-18
Abstract: An improved horizontal crossbar multiswitch utilizes a modified armature assembly comprising several component parts that cooperate when the bar is in a rest position to provide a magnetic field of minimum reluctance in cooperation with an associated electromagnet, and when the bar is in an operating position provide a magnetic field of maximum reluctance by increasing the gap existing between the associated electromagnetic coil and one of the armature component parts.
