Abstract: A computer device comprises a logic system and a computer-memory system operatively coupled to the logic system. The computer-memory system holds instructions that, when executed by the logic system, cause the computer device to instantiate a node of a blockchain having verifiable provenance. The blockchain includes a requestor block configured to specify at least one requested feature of a requested product and an offerer block cryptographically linked to the requestor block. The offerer block includes data obtained by automated testing of an offered product, which reveals the level of compliance of the offered product with respect to the requested feature through product feature life cycle of validation, test, verification and acceptance.

Abstract: Embodiments described herein provide verification of robotic assets for a production work cell via simulation. A production workflow for the production work cell is received from a user, and a simulation is generated based on the production workflow. The simulation of the work cell controller design is executed using performance data for the robotic assets, and a determination is made whether the robotic assets meet or exceed the design requirements of the robotic assets based on the simulation. The result of the determination is presented to the user.

Abstract: Systems and methods are provided for insulation and moisture drainage. One exemplary embodiment is a bay blanket configured to insulate an aircraft. The bay blanket includes insulation, and a first trough running along a length of a leftward face of the insulation and adapted to receive water draining from an outboard side of the insulation. The first trough includes sidewalls that meet at an inboard side of the insulation and extend from the inboard side to the outboard side. The bay blanket also includes a second trough running along a length of a rightward face of the insulation and adapted to receive water draining from the outboard side. The second trough includes sidewalls that meet at the inboard side and extend from the inboard side to the outboard side.

Abstract: The present invention comprises a self-actuating blow forward firearm having a fixed breech block located to the rear of the firearm. A cartridge feeder provides a supply of cartridges to the loading area so that the firearm can be used as an automatic or semi-automatic weapon. The firearm also contains an outer receiver tube and a movable inner gun barrel which is biased toward the rear of the firearm by a spring disposed in a chamber between the receiver tube and the inner movable barrel. When the trigger mechanism is activated, the action of the bias spring causes the inner movable barrel to move backward toward the breech block striping a cartridge from the feeding device and forcing the end of the cartridge against the firing pin on the breech block. The bullet is fired down the bore of the inner movable barrel. The movement of the bullet along the bore of the inner movable barrel drags the barrel forward against the action of the bias spring.

Abstract: There is disclosed a loading platform mounted cantileverally from a vertical spindle carried from a walkway, such mounting being by means of a horizontally extending pivot for rotation of such ramp from a lowered position extending over a loading station to an elevated retracted position adjacent the walkway. A locater is mounted on the swing post for selectively controlling ramp positioning to various angular locations. A ramp extension is slidably mounted for longitudinal extension from the ramp itself. The ramp is counterbalanced to be normally urged to its elevated and retracted position.

Abstract: An improved gas locked firearm using expanding gases to force a bullet through a barrel in which a portion of said gases are diverted through a gas port communicating with a gas locking chamber adjacent said barrel which chamber is formed between said barrel and an extension arm of the bolt or breech block extending forward therefrom a distance along the rear portion of the barrel and forming an elongated gas chamber between a shoulder on the rear of the barrel and a plate extending from said breech block extension in a manner to trap the expanding gases between said barrel shoulder and said plate to lock the breech block in a forward position while gas pressure exists in the barrel and provided with additional gas ports in the breech block extension and plate to vent remaining gases as the firearm action cycles.
