Title: Increased lift aircraft wing - has span-wise hinge with rear flaps to help maintain boundary layer flow at low speeds
IPC: B64C3/50
Filed: 1978-04-03
Abstract: The lift of an aircraft wing is considerably increased at low speeds by dividing the wing into two parts which are joined by a hinge extending from the fuselage to the wing tip. The hinge is actuated by hydraulic or electric power so that the camber of the wing is increased during take-off and landing. The performance of the wing is still further improved by the addition of flaps along the trailing edge. These devices delay the onset of stall by maintaining the boundary layer flow at low speeds.

Title: Drive mechanism for loom take=up motion - has pulley driving support cylinder operated through free wheels pneumatically
IPC: B65H18/20
Filed: 1978-04-17
Abstract: A driving roller transmits its motion by contact, to the successive layers of a material in sheet form, wound on to a tubular support. The roller forms part of a device for ensuring the winding on of the sheet material at a constant tension, irrespective of the speed at which it is delivered. The rotation of the roller is effected by the intermediary of a non-return system. This acts on the shaft of the roller, according to the amt. of material delivered, and is formed basically by two elements mounted on the driving shaft. Each non-return element is commanded by a jack, the piston of which acts on the end of a lever fixed solidly to the driving shaft, and causes its angular displacement. After having acted the jack is maintained at a constant predetermined pressure corresponding to the tension to be applied to the sheet material. System is esp. for the take-up mechanism of a loom. The need for expensive mandrels which are difficult to lift out when full and to replace with an empty, is avoided, and fragile electronic controls are also dispersed with. The device is simple to install and adjust.
