Abstract: A glider comprising a pair of wings having overlapped forward, inner root portions that are freely pivotally connected and tailfins on rearward, outer portions of the wings. The tailfins are angularly offset from the general longitudinal axes of the wings so as to have an airfoil liftout angle of attack to the relative wind during flight which causes the wings to swing out to an extended configuration.

Abstract: A system for actuating a normally engaged clutch of a manual transmission type vehicle in which clutch re-engagement is sequenced in a plurality of steps or stages. A source of a first pressure level is employed to operate a clutch servo, and a clutch re-engagement control chamber having a second pressure level therein is employed in the stepped clutch re-engagement cycle. A solenoid valve, when energized, connects the source of the first pressure level to the servo to operate the servo and disengage the clutch, and at this time isolates the re-engagement control chamber from the servo. Then upon de-energization of the solenoid valve the source of first pressure level is isolated from the servo and the control chamber is substantially simultaneously connected to the servo so as to allow partial release of the first pressure level from the servo and thereby effect a first stage of clutch re-engagement.
