A vertically stabilized shelf bracket assembly having at least two support strips on which a plurality of shelf brackets are mounted. The shelving is stabilized in several ways. First, the brackets are provided with a shelf engaging recess. The recess is either designed to provide a tight fit for the shelf, or the recess is provided with a shim for tightening the fit. Second, the brackets are provided with a vertical member which engages the shelves. Preferably, the recess and the vertical member will engage the shelf at opposite ends of the shelf, securing the shelf to the bracket. When the shelf is attached to multiple brackets, the shelf will be prevented from pivoting on the bracket. The shelves can be further stabilized by securing the brackets against vertical displacement. This can be accomplished by securing the shelf brackets to the support strip with a locking pin. With the locking pin in place, the shelf bracket cannot be moved upward. Another way of securing the brackets is to provide a vertical stabilizer, comprising an elongated member, preferably of steel or aluminum, having an arm extending perpendicularly therefrom. The arm will fit tightly into a slot in a support strip. When the arm is in place, the elongated member will be positioned over and in contact with the base of the shelf bracket, so that the bracket cannot be moved upward. The vertical stabilizer will be held in place by the cover which fits over the support strips.

The present invention provides an unmanned airborne reconnaissance vehicle having a fuselage, a forward wing pair and a rearward wing pair vertically separated by a gap and staggered fore and aft therebetween such that a general biplane configuration is formed. The present invention provides a pair of wing tip plates for joining the wing tips of the forward and rearward wings. The unmanned airborne reconnaissance vehicle of the present invention includes a power plant to propel the vehicle through the air and a generally T-shaped tail having a vertical stabilizer including a rudder and a full span elevator.

An aircraft features a source of forward thrust on a fuselage having a helicopter rotor assembly and an asymmetric primary wing configuration providing more wing-generated lift on one side of the fuselage than the other. The primary wing configuration counteracts the rotor's dissymmetry of lift during forward cruising, and reliance on the separate thrust source for such cruising reduces demand on the main rotor, keeping the angle of attack on the rotor blades low to avoid the stalling and violent vibration experienced by conventional helicopters at relatively high speeds. In some embodiments, an oppositely asymmetric tail wing or horizontal stabilizer acts alone, or together with an offset vertical stabilizer laterally outward from the tail, to counteract yaw-inducing drag of the primary wing.

Mechanical separators and screening machines, and methods for flexible sieve mat screening and flexible mat conveying are disclosed. In an example configuration, a flexible mat screening apparatus is provided with geometrically optimized guiding edge seals at lateral sides. One preferred configuration includes an assembly wherein a sieve mat has upwardly curved lateral sides forming a non-vertical, gradually curved shape. In another configuration, a movable support section is supported on a main frame section via a plurality of shear blocks, each arranged with its compression axis disposed horizontally. In yet another configuration, the movable support section is further connected to the main frame section via vertical stabilizers or leaf springs, the vertical stabilizers permitting longitudinal movement between the movable support section and the main frame section, but inhibiting vertical and/or lateral movement therebetween.

A system support assembly comprises a pair of substantially parallel footer forms, insulated concrete forms, footer form base saddles, a poly form saddle assembly and first and second vertical stabilizers. The footer form base saddle may be generally u-shaped and is driven into the ground forming two substantially parallel areas. Each footer form is placed within the row formed by the footer form base saddles such that a cavity is defined therebetween which will ultimately form the footer of the foundation. The poly form saddle assemble comprises a poly form saddle and fasteners. The poly form saddle may also be generally u-shaped and is placed over both footer forms, thus straddling the same. The poly form saddle may then be secured with corresponding fasteners. The insulated concrete forms are placed side by side and are stacked upward, such that a wall is formed. A first poly form vertical stabilizer is placed over the wall and operatively connected to the footer form base saddle. More insulated concrete forms are stacked to complete the wall. The second poly form vertical stabilizer may then be placed, preferably laterally spaced from the first poly from vertical stabilizer. The second poly form vertical stabilizer is also operatively connected to the footer form base saddle. Then, the concrete is poured into the insulated concrete forms such that the foundation wall and footers are poured and cured at one time.

A remotely controlled model airplane includes a receiver responsive to signals from a transmitter to control the direction of flight of the model airplane. The receiver, powered by a battery, demodulates the signal transmitted by the transmitter to selectively energize an electrical coil to generate a magnetic field of a first or second polarity. A rudder pivotally attached to the vertical stabilizer includes a magnet responsive to the magnetic fields generated and is urged in one direction or the other resulting in commensurate pivotal movement of the rudder. A hinge interconnecting the rudder and vertical stabilizer urges return to center of the rudder after it has been deflected left or right by the magnet responding to the magnetic field created as a result of a signal transmitted by the transmitter. An electric motor also under control of the transmitter and receiver may be incorporated to rotate a propeller to provide thrust and forward motion of the model airplane. By employing a transmitter to selectively transmit a plurality of signals, control surfaces of the model airplane can be deflected to provide 2-axis control to selectively alter the direction and pitch of the model airplane.
