Abstract: A lay-up method of composite aircraft parts with an opening. Composite tows having an orientation of 0°, 90° or +/?45° are laid up forming plies which form a composite laminate. Each tow having an orientation of 0° and being within the perimeter of the opening comprises: a first gap located at approximately ? of the length of the first semi-major axis from the center, the first gap being configured as a first elongated gap longitudinally perpendicular to the orientation of the tow, and a second gap located at approximately ? of the length of the second semi-major axis from the center, the second gap being configured as a second elongated gap longitudinally perpendicular to the orientation of the tow.

Abstract: A method for reworking a composite laminate comprising a plurality of tapes, comprising the following steps: detecting the occurrence of a defect on a tape of composite material while the tape is being laid up; continuing the lay-up of the defective tape until a tape length is formed which surpasses a manufacturing length of the tape; catching the part of the defective tape that surpasses the manufacturing length of the tap; cutting the defective tape in the part of the defective tape that surpasses the manufacturing length of the tape; removing from the laminate the caught defective tape by the catching system, and laying-up a replacement tape in the place of the removed defective tape.

Abstract: A fishing rod holder with automatic pull that operates unattended and automatically pulls when a force of predetermined magnitude is applied to the line. The holder includes a housing where an assembly for removably holding a fishing rod is pivotally mounted and movable between two extreme positions. The housing includes a stopper member cooperatively mounted outwardly to coact with the locking mechanism. A spring assembly biases the holder assembly towards the rearmost extreme position and a locking assembly for releasably holding the rod holder keeps the latter at the foremost extreme position. A trigger sensing the tension of the fishing line is automatically actuated by exceeding a predetermined tension magnitude causing it to pivot and transmit a rotational movement to an elongated member. The other end of the elongated member includes a spring biased retractable chamfered pin. The pin has a slanted termination and a flat termination.

Abstract: A system and method for evaluating and comparing businesses and, more specifically, to an Internet-based benchmarking or management tool or platform that provides one or more metrics by which a business owner may anonymously track, evaluate and compare the relative condition of its business with other similarly situated businesses of the same or related type whereby the one or more metrics are based upon the business' quantifiable data (e.g., profits, movement of inventory, etc) that is indicative of the business' operations such that a business owner may implement improvements to the business' operations in response to the information provided.

Abstract: A stabilizing mechanism for rigid fixed and extension ladders that includes an anchorage assembly removably mounted to one of the rungs of a ladder. A linkage assembly is mounted to the anchorage assembly and it supports a rigid elongated member that in turn pivotally supports two arched arm members that are selectively locked in place by a locking assembly that can be remotely actuated. The arm members embrace a support member thereby providing a firm engagement of the ladder assembly to the support member. A release mechanism remotely disengages the ladder from the support member once a user descends.

Abstract: A device for base sheet fasteners used in conjunction with nail gun. The nail gun includes main and security triggers that a user has to simultaneously activate while lifting and dropping the nail gun. A slidable spring loaded longitudinal member is pushed back in line with the housing of a receiving assembly causing a leg to activate the safety trigger. This allows a user to place a base sheet fastener onto a magnetic hammer while the hammer is in the retracted position and upon dropping the nail gun, the magnetic hammer automatically strikes the surface thereby nailing the base sheet fastener in a safe and efficient manner. The resulting device permits the continuous installation of base sheet fasteners on a surface. A substantially cylindrical assembly is provided with a longitudinal cutout with cooperative dimensions to receive the base sheet fasteners.

Abstract: A hydraulic valve for controlling the flow of a pressured liquid with a housing that has an inlet and an outlet with a pivotally mounted handle that actuated a valve stem member housed within an internal bore with a counter bore step surface. An O-ring member is mounted on the step surface that comes in contact with a convex surface provided in a peripheral flange member on the stem member. A compressible cylindrical member is trapped partially within an opening at one end of the valve stem member urging the convex surface against the O-ring thus blocking the flow of the pressurized liquid through the internal valve bore.

Abstract: A tin cap dispenser for pneumatic nail guns that include a continues source of nails. The dispenser is also pneumatically activated and coupled to the operation of the nail gun. A pneumatically actuated handler arm member is reciprocally moved between two positions, one engaging a tin cap and the other one releasing it in alignment with a positioned nail also in coaxial alignment with the hammer of a nail gun. The timing of the tin cap handler arm member controls a valve assembly in series with the conventional trigger mechanism of the nail gun and another valve also in series that is activated by the handler arm member. A lock assembly inhibits the operation unless sufficient time is given to the feeding nails mechanism to get out of the way. The resulting device permits the continuous installation of tin caps on a flat surface.
