Abstract: The invention claims an adjustable putting aid that improves a golfer's short game by creating a visual guide for the golfer to use during their swing. The visual guide is situated higher than and out in front of the ball when the golfer is addressing the ball. During the pinnacle of the backswing, the visual guide should obscure the golf ball from the view of the golfer. The visual guide creates a path for the golfer to follow and this improves the arching in the backswing, the length of the backswing, shoulder stability and can help improve the golfer's rhythm and tempo.

Abstract: A V/STOL aircraft includes an aft by-pass powerplant 28 having an aft, rearwardly directed nozzle 30 and twin transverse vectorable nozzles 32. A duct 29 extends forwardly of the powerplant and terminates in a vectorable nozzle 16. The duct supplies relatively cool by-pass air to the nozzle.

Abstract: A transmission includes an input shaft having an internal bore at one shaft end and a main shaft having an extension formed at one shaft end that is received within the internal bore. The internal bore is defined by an inner peripheral surface and the extension is defined by an outer peripheral surface that is spaced apart from the inner peripheral surface. A resilient member is positioned within the internal bore and reacts between the inner and the outer peripheral surfaces to center the main shaft and the input shaft relative to each other.

Abstract: A valve actuating apparatus for providing proportional control of a fluid flow that includes a housing having a valve body with an inlet port and an outlet port. In one embodiment, the valve actuating apparatus also has a valve assembly including an armature, a movable fluid control member, and at least one spring biasing the armature into contact with the fluid control member. The valve actuating apparatus further includes a solenoid assembly having an electromagnetic coil and a pole piece. The pole piece and the armature define a gap that changes proportionally with the amount of current flowing through the electromagnetic coil. Fluid flow from the inlet port to the outlet port may proportionally increase or decreases as the gap increases or decreases. The valve actuating apparatus may further include a valve seat. The fluid control member may be in contact with the valve seat to inhibit fluid flow through the apparatus when the electromagnetic coil is not energized.

Abstract: Apparatus for use in performing intercourse includes a frame having an operative side, and a swing assembly. The swing assembly has at least two suspension joints. This swing assembly is attached to the frame through the two suspension joints to allow the assembly to swing arcuately. The two suspension joints are reciprocatable about different centers of gyration. The swing assembly has a platform allowing a first person to rest thereon and provide genital access toward the operative side. The swing assembly has clearance to allow a second person to stand adjacent the platform and gain access to said first person from the operative side as the swing assembly swings arcuately.

Abstract: A radar shield, in particular for an aircraft radar antenna, comprises a plurality of elongate triangular blinds 6 that may be stowed on individual rollers 7. To deploy the shield, the blinds are drawn from the rollers by wind-up spools to form a pyramidal shield within, for example, the aircraft radome assembly.

Abstract: The tailplane 6 is mounted to an aircraft by a spigot 7 and is also rotatable about the spigot 7 to provide aerodynamic control. At the same time the tail plane is pivotable about an axis extending generally parallel to the longitudinal axis of the aircraft in order to optimise the tail plane configuration for various speeds.
