The auxiliary bin is attachable via a bracket to the grid work of the existing grocery cart. A latch holds the auxiliary bin in the collapsed position when it is not in use.

Abstract: Once the rotor of a rotary-wing aircraft is held stationary in an indicated position, the method comprises steps consisting in placing the collective pitch control stick in a first predefined position corresponding to a first inclination of the blades about their longitudinal axes, in placing the cyclic pitch control stick in a second predefined position corresponding to a nose-up position of the rotary-wing aircraft, in modifying the length of the control system to cause the inclination of the blades about their longitudinal axes to go to a second value that is different from said first inclination value, in holding a rotary swashplate stationary by placing at least three locking connection rods between the rotary swashplate and a member integral in terms of rotation with a rotor mast, and in folding the blades by rotating each of them about a corresponding coupling pin for coupling it to a coupling member for coupling the blade to a rotor hub.

Abstract: A throttle valve body (1) including a flap (6) of which the side pivoting down or up on opening has a shoulder (17) on the flap surface facing upwards or downwards, respectively, defining a gradually widening cross-sectional area with the cylindrical (7) or frusto-conical (9) wall opposite the intake channel (3) through the housing (2). The side of the flap (6) which rotates up or down, respectively, on opening consists of a flat half disk of which the edge is , at first, opposite a tapered surface portion (14) with a complex shape to define a gradually widening cross-sectional area downstream from an inlet convergent (15,12) and upstream from an outlet divergent, respectively.

Abstract: A mechanical device that dynamically, through the change in velocity-caused sheer planes, effectively produces a more homogenized mixed phase flow stream downstream from a non-homogenized phase concentrated stream. The device is unique in that it does not rely on physical contact with mechanical surfaces of each phase in the stream to re-direct the phases into a re-distributed mixture. This effect is generated dynamically with the pressure differentials caused by sheer planes and dynamic recirculation zones at different velocities. This differential pressure gradient is developed by inserting a pre-designed non-aerodynamic symmetrical device in a mixed phase flow path to produce a re-circulating flow disrupting the laminar flow characteristics. The diffuser design is based on a proprietary calculation methodology based on the physical arrangement of the stream containment. This arrangement may be rectangular, conical, round, oval, multi-sided or annular in configuration.

Abstract: A collapsible ramp construction 10 for physically challenged bowlers and including a contoured ramp unit 11 supported by a collapsible framework unit 12. The upper end of the ramp unit 11 is provided with a ball release unit 13 which includes a ball receiving member 40 operatively associated with an actuator member 46, wherein movement of the actuator member 46 will releasably engage a bowling ball 100 from the ball receiving member 40.
