Abstract: An add-on spare tire and method for installation in which the spare tire includes a first (6a, 103) and second wheel half (6b, 104). The first wheel half (6a, 103) includes an attachment plate portion that is attached to the wheel (20) carrying the flat or disabled tire (1). Once attached, the first wheel half (6a, 103) is rotated until the first wheel half (6a, 103) supports the weight of the vehicle. Finally, the second wheel half (6b) is attached to the first wheel half (6a).

Abstract: A run-flat tire that consists of about eight to twelve free-standing, separate and independent inserts, bonded to the inside of a conventional tubeless tire (30) that is mounted on a conventional one piece drop center wheel (31). The accompanying drawing shows a cross section view of one of these inserts in the tire. Each insert consists of a pair of rigid, load supporting, spread-apart legs (33); a rubber rim pad (34); a pair of rubber foot pads (35) which are bonded to the inside of opposite tire bead flanges.The rubber rim paid is bonded to the top of the leg pair to permit the legs to swing in and out, which is necessary during mounting and demounting the tire from the wheel. The pair of rubber foot pads are made to permit each leg pair to swing back and forth, independently, as needed, under run-flat driving. This tilting of the inserts automatically compensates for the difference between the rolling circumference of the set of inserts and the rolling circumference of the tire.

Abstract: A porous aircraft skin for wetted areas of an aircraft employed in conjunction with a suction system of the aircraft to draw air inwardly through pores of said skin for laminar flow control. The porous skin is compliant and includes a thin outer skin with fine pores bonded to a lower substantially thicker coarser pore compliant skin with the thicker skin in turn bonded to the structural skin of the aircraft. Vacuum chambers beneath the aircraft structural skin receive air sucked through the porous compliant skin and through communicating holes of the structural skin. One-way valves of flexible or semi-flexible material are inserted into the suction holes of the aircraft structural skin prior to the placement of the porous compliant skin. Low pressure above the aircraft lifting surfaces automatically closes the one-way valves thereby maintaining low pressure above the lifting surfaces and preventing reverse flow from destroying the lift afforded by said surfaces.

Abstract: A universally flexible rotor mast for a rotary wing aircraft wherein the universal flexing of the mast is accomplished by the use of multiple elastomer mounts of elastomer metal plate sandwich formation and with high strength cables embedded in the elastomer and anchored to opposing metal plates of the sandwich mounts. A static on-ground rotor mast lock is employed to secure the rotor mast in an upright position, the mast lock is used in conjunction with the elastomer mounts of the flexible mast.

Abstract: A vertical take-off and landing aircraft features an improved tail-lifting rotor and rotor directional controls. A new type of suction pressure jet-mechanical-flap rotor blade with a higher coefficient of lift is employed. The aircraft has a mechanism for loading and unloading passengers and a more efficient method of handling baggage and cargo. A much more efficient utilization of space in the fuselage is achieved through a reduced height passenger space and overhead rotor storage compartment.

Abstract: An aircraft fuselage with a rear opening door and a pair of tracks in the bottom of the fuselage for a roll-in-roll-out cable train consisting of a series of connected cable cars. The cable cars are constructed so that the floor of the aircraft is part of the cable cars with passenger seats above the floor and baggage compartments attached below the floor. The entire cable train can extend rearwardly of the fuselage and into a separate adjacent building without disconnecting the cable train from the cable drive unit in the aircraft floor.

Abstract: A key operated locking unit is permanently attached to a bicycle frame member. A flexible tether has one end permanently secured to the bicycle locking unit and has a plug-in lock element on its free end adapted to enter a receiver on the locking unit after first being looped around a stationary anchoring member and around part of the bicycle frame. Locking of the bicycle becomes essentially a one hand operation in the shortest possible time.

Abstract: Foam glass developed under vacuum is continuously formed into a slab while being cladded on its major sides and longitudinal edges with sheet metal. The metal claddings or facings for the two major sides of the slab are held under tension during the solidifying of the slab body. End plates are inserted transversely through the product at specified points during its movement and sections of the continuous product are cut to length, whereby the sections are prestressed partly as a result of compression along two axes caused by differing coefficients of expansion of the cladding and foam glass body and partly to atmospheric compression of the product on a third axis perpendicular to its major sides. Modified forms of the product eliminate the metal cladding or skin entirely or provide the same as a cast-on coating without mechanical prestressing.

Abstract: Essentially L-shaped housing modules used to construct a multi-level apartment building are transported to an erection site on a flat bed trailer drawn by a winch-equipped towing truck. An identical truck is used to tow a construction crane tower to the site on a trailer vehicle which is later utilized as a counterweight for a simplified fixed radius non-rotating crane based on one of the trucks and erected by use of the second truck. Twin opposing cranes are employed to lift and manipulate housing modules at the site. A special lifting truss with hinged transverse extensions is employed in conjunction with the twin cranes and has means for coupling to each housing module so as to add to the rigidity of the latter. Worker platforms on the crane towers have manual winch means for making fine adjustments in the attitude of each module so that the module can be correctly set into place on underlying modules or on a prepared foundation.

Abstract: .[.An anti-theft locking system for bicycles or other portable items utilizes a high strength hollow flexible tether which may be looped around the stationary object and plugged into a locking receiver or socket on the bicycle or, alternately, may be plugged directly into a locking opening provided in a hollow post such as a parking meter post.
