Filed:

Appl. No.:

8/007327

Inventors:

James L. Nasset - Aumsville OR

International Classification:

F16H 528

US Classification:

477 81

Abstract:

A shift control device for a vehicle's automatic transmission that cannot normally be locked in second gear, but will automatically downshift from second to first gear under predetermined conditions. The shift control device includes a power translator connected to a S-2 shift solenoid of the vehicle, a manual control switch, a frequency-to-voltage converter for receiving a speed signal of the vehicle, and a voltage comparator for comparing a throttle signal of the vehicle and the output from the frequency-to-voltage converter. Without the shift control device, a downshift--in one particular type of transmission--is normally effected when the S-2 shift solenoid is deactivated by the transmission controller. The shift control device is connected to the S-2 shift solenoid in parallel with the transmission controller. When the manual control switch is operated by a user, and the throttle and speed signals are within predetermined ranges, the power transistor will be biased to maintain the S-2 shift solenoid in an activated state independently of the transmission controller to inhibit automatic downshifting.

Abstract:

A harmonic vibration tuning device is provided in the forestock of a rifle engaging a cantilevered barrel forward of the rifle action, for the purpose of effecting a change the harmonic vibration frequency of the barrel, that is generated, as a projectile moves through the barrel to the muzzle. This adjustable change in the harmonic vibration frequency of the barrel causing a controllable change in the impact placement of a plurality of fired projectiles. The harmonic vibration tuning device of the preferred embodiment includes a containment assembly that is mounted in a cavity formed in the forestock. The assembly includes a threaded adjustment shaft extending horizontally through the assembly with the shaft being threadedly mated with a reactive contact means. The reactive contact means, of the preferred embodiment, engages the surface of the barrel permitting a force to be exerted between the forestock and the barrel. The threaded shaft protrudes toward the front surface of the forestock to enable it to be rotationally adjusted.
