Abstract: A device for roof structures having a ridge or hip defined by the planes of two roof decks, disposed at an angle with respect to each other defining a longitudinal joint. A longitudinally extending cover with at least one coextensive channel defined by a bottom, two spacer walls and two lateral walls are mounted over the ridge or hip. The channel(s) increases the effective contact area to enhance the gripping action of the adhesive compound. From the longitudinal bends of the cover wall extend two perpendicularly extending walls with distal ends that continue with longitudinally coextensive flanges. The longitudinal flanges extend at an angle to be cooperatively and rigidly mounted over the roof decks with mechanical fasteners. An adhesive compound is positioned in the channel and over the cover.

From the longitudinal bends of the cover wall extend two perpendicularly extending walls with distal ends that continue with longitudinally coextensive flanges. The longitudinal flanges extend at an angle to be cooperatively and rigidly mounted over the roof decks with mechanical fasteners. An adhesive compound is positioned in the channel and over the cover. The adhesive is pressed so that part of it protrudes through the through openings positioned along the bottom, spacer and lateral walls that define the channel thereby creating a mechanical anchorage with the device.

Abstract: An apparatus and method for molding composite material with a selectable uniform predetermined temperature during most of the curing time. The mold apparatus has two cooperating and complementing mold bed assemblies hingedly mounted to each other and movable between two extreme positions, open and closed. A composite inner skin and outer skins sandwich a spacer in between. The spacer member includes interconnecting passages throughout. An outer perforated composite skin member covers the spacer member. A source for pressurized gas is applied to the mold assemblies when in the closed position. A predetermined cooperative temperature is selectably used to uniformly control the curing characteristics of the first and second skin members as the pressurized hot gas or air forced to pass through the outer skin and the spacer member adjacent to the inner skin thereby exposing the form being molded to a uniform temperature gradient.

Abstract: A shelf system for corner walls where the shelf members are supported against two perpendicularly disposed walls without showing any mounting elements. The shelf member includes at least two contiguous sides defining edges of a predetermined thickness and perpendicular to each other. Tongue members extend for the sides and are receivable within cooperative wall cavities for a snug mechanical engagement. Adhesive is applied to the sides to immobilize the shelf member and thus enhance the structured integrity of the system.

Abstract: A table and umbrella assembly capable of withstanding lateral forces by providing an overall center of gravity below its top. Two collar lock assemblies are removably mounted to a pole assembly that passes through the top center. The umbrella pole assembly, when tubular, may include a weight introduced to the lowermost member. The weight may be either solid or liquid and does not extend above the top.

Abstract: A safety seat with air enclosure mechanism for infants that permits its retrieval from a body of water with a significant amount of air to extend the breathing time of the enclosed child and prevent drowning. The seat includes a compartment for a flexible enclosure that can be readily deployed to temporarily enclose the seat assembly and infant completely for their easy retrieval from dangerous conditions. A spring loaded roller or winding mechanism keeps one end attached while the other end is open and stretchable to cover the infant and the seat assembly. The spring loaded winding mechanism keeps the enclosure tense to facilitate its deployment by a user.

Abstract: A moving platform system with a base firmly anchored to a supporting surface and an upright structural member extending therefrom. A bifurcated arms assembly is mounted to the distal end of the structural member supporting a cross bar assembly. The bifurcated arms assembly includes two outwardly extending arms that support two of the four legs of the cross bar assembly. The other two legs support the platform that in turn supports the object being displayed or used as an entertainment structure. An electric motor is used to provide rotational movement to two wheels of different diameters. The wheels are pivotally connected to linkage arms at an offcentered position that provide the reciprocating sinusoidal movement to the platform with different frequency characteristics.

Abstract: A volumetric efficient collapsible and tamper proof container for protecting goods contained therein during transportation and storage. The container comprises six walls perpendicularly and hingedly mounted to each other to define a cubic space therein. Long and short elongated pins are passed through openings in knuckle extensions on the sides of the walls and they are cooperatively disposed to offset each opposite tubular member to permit the coaxial alignment of the respective through openings. Locking tubular members are used to keep one or more of the long pins in place. The long pins keep the shorter pins in place. Seal members are used to prevent the removal of one or more of the long pins that are keeping the short pins in place. The other long and short elongated pins are kept in place with locking tubular members that can only be removed when the walls are flat on a common plane.

Abstract: A mechanism for guiding roll up doors made from a foldable sheet. A longitudinally extending wall of the foldable sheet is secured to a fixed structure and two longitudinally extending lateral walls extend perpendicularly to form another two reversible folds resulting in two longitudinally extending inner walls at a spaced apart and parallel relationship with the two lateral walls. From one of these inner walls, a longitudinal wind bar extends at a predetermined cooperative angle. Upon the application of a wind load to the door slats, the load is transmitted to the foldable sheet guiding assembly from the slats directly and through the wind lock assembly through at least four contact points. The laterally articulated door slats include longitudinal hook portions or wind lock assemblies that slidably coact with the wind bar to keep the slat in place.

Abstract: A construction block system that includes a block with slanted edges that coact with contiguous blacks to define spaces or grooves for receiving cementitious substances. Cooperatively aligned channels in the upper and lower edges coact with longitudinally extending walls perpendicularly mounted to a base assembly. An adjustable mechanism provides for leveling of the base assembly to ensure proper installation of the lowermost row of blocks. Subsequently rows are aligned and leveled with a leveling tool assembly that is also partially received within the cooperative channels.

Abstract: A yawing system for a wind turbine, the wind turbine comprising a tower fixed to the ground and a frame (1) housing an electric power generator, the tower and the frame (1) being joined by the yawing system which allows the orientation of the frame (1) with respect to the tower according to the direction of the wind. The yawing system comprises: a gear ring (2) fixed to the tower, the gear ring having a sliding track (3) on which the frame (1) rests and slides in its yawing movement, at least one geared motor fixed to the frame (1), meshed with the gear ring (2) through a gear wheel, at least one active braking module (5), and at least one passive braking module (6). The invention further comprises a sliding track (3) and a friction track on the gear ring, this friction track (10) being different from the sliding track (3), and the active braking modules (5) and passive braking modules (6) comprising a friction plate (11) acting on the friction track (10) of the ring.
