Abstract: A double pole, double throw rocking contactor switch is operable as a reversing switch by particularly configured stationary contacts at the corresponding ends of the respective poles. Stationary contacts are formed electrically common out of a single member having the stationary contact of one pole formed to be disposed below the rocking contactor and the stationary contact of the other pole formed to be disposed above its respective contactor. Accordingly, one contactor engages the upper surface of a stationary contact while the other end of the other contactor engages the under surface of the opposite stationary contact for a given stable position of the actuator, thereby causing the respective contactors to engage stationary contacts at respective opposite ends of the contactors, accomplishing the reversing function internally of the switch without special cross connect conductors, thereby permitting press-in wire terminations to be utilized.

Abstract: An electrical switch includes a rocker-type actuator adapted to be pivoted between first and second positions within a housing in order to close and open switch contacts.

The actuator may be returned to its switch-open position by a simple single motion thereby enabling rapid opening of the switch under emergency conditions. In one embodiment, the latch cannot be moved to an unlatched position and the switch cannot be actuated unless an authorized person with a key connects the key detachably to the latch.

Abstract: A horizontally moving vehicle body may b stabilized and held at a constant vertical level, as its wheels move up and down in response to disturbing forces, by utilizing the kinetic energy of the rotating wheels to create counter forces on the vehicle body in the direction opposite to the disturbing forces to counterbalance the disturbances. As a disturbing force moves a wheel downward (assume the wheel falls into a hole in the road), a vertical force is imparted toward (against) the vehicle body to effectively push the wheel downward and away from the body, the body thereby remaining at its normal level and not following the wheel. On the other hand, when a wheel moves upward (assume it rides over a bump in the road), the kinetic energy of the wheel is converted to a vertical force in the direction away from the vehicle body to lift the wheel upward and force it toward the body, as a result of which the body remains undisturbed at its normal level and will not follow the upward movement of the wheel.

Abstract: A calibration system for the keyboard of an electronic musical instrument. Compression of the key causes an output signal to be generated which varies in accordance with the amount of key depression. When the key is depressed to a nominally fully depressed position, the system stores an offset value relating to the difference between the actual output signal at this point and an expected reference output signal which would occur if the keyboard were perfectly adjusted from a mechanical standpoint. The offset value is stored in the memory and added to the key output signal during the normal operate mode of the instrument so that the output signal is adjusted in accordance with the offset value stored during the calibrate mode.
