| 1 | Delayed snap action microswitch | US3746808D | 1972-01-17 | US3746808A | 1973-07-17 | BECHTIGER C |
| A microswitch having a snap action, wherein depression of an operating button to a predetermined joint first tensions an operating spring, then when moved beyond the point releases an operating lever which starts a delay mechanism, and finally causes a rapid action of the contacts of the switch.

| 3 | Locomotive controller with throttle escapement | US3710055D | 1971-06-15 | US3710055A | 1973-01-09 | BLONN G |
| A locomotive controller in which a throttle handle assembly is selectively capable of operating as an engine power control or as a dynamic brake control as controlled by the action of a selector lever. The mechanism incorporates detent means which are effective only during action of the throttle handle as an engine power control to position the handle in any selected one of the predetermined throttle positions. An escapement mechanism acts to prevent continuous power increasing movement of the throttle handle past at least the first and second throttle positions when in the power mode. The escapement is disconnected from the throttle handle assembly when the dynamic brake mode is selected, thus providing an unmistakable indication to the operator, when he advances the throttle handle, of whether the unit is operating in the power or dynamic brake mode without requiring his observation of the control panel.

| A multi-pole surface acoustic wave notch filter and an RF(Radio Frequency) filter using the same are provided to obtain a wide band-stop range by having a plurality of resonators with different anti-resonant frequencies. A multi-pole surface acoustic wave notch filter includes a plurality of resonators(N1,N2). The resonators are series or parallel resonators and arranged in one chip. The resonators have different anti-resonant frequencies(f1,f2) from each other. The multi-pole surface acoustic wave notch filter further includes a matching element. The matching element is positioned outside the chip where the resonators are arranged. A band-stop range of the multi-pole surface acoustic wave notch filter is controlled by changing the number of the resonators. | ||||||
