Vise pins can be received by the jaw pin holes and vise pin holes to fixedly connect the support device to the vise.

US12384337 - Military vehicle

A military vehicle assembly includes a rear module. The rear module includes a rear frame assembly, a bed supported by the rear frame assembly, a rear tractive assembly, a transaxle supported by the rear frame assembly and coupled to the rear tractive assembly, and a rear suspension system including at least one component extending between a housing of the transaxle and the rear tractive assembly. The rear frame assembly has one or more upper interfaces and one or more lower interfaces. The one or more upper interfaces are configured to detachably couple to a rear end of a passenger capsule of a military vehicle. The one or more lower interfaces are configured to detachably coupled to a bottom of the passenger capsule. The transaxle is configured to couple to a prime mover and a front differential of the military vehicle.

US12384901 - Composite materials for anti-ballistic applications and methods of fabrication thereof

A composite material, methods for its fabrication and example applications. The composite material comprises a polymer having a carbon allotrope incorporated into the polymer's crystalline structure. The material is characterized by a crystallinity greater than the native crystallinity of the polymer in the absence of the carbon allotrope being incorporated into the polymer's crystalline structure. The composite material is non-laminate, substantially excludes metals, ceramics, and cermets, and is electrically conductive. The carbon allotrope serves as a bridge between a first region of the polymer and a second region of the polymer. The fabrication method involves mixing a powder of polymer and carbon allotrope particles, suspending the powder in a solvent, spinning the solution into fibers, and drawing the fibers into a composite material. Applications include collecting data responsive to stimulating the composite material, comparing the data to thresholds, determining the material's condition, and transmitting a decision regarding its continued use.

US12385197 - Tire deflation device

A pressure-tight container pressure control assembly is configured to adjust internal pressure in a pressure-tight container. The pressure-tight container pressure control assembly has a housing having an attachment end. wherein the attachment end is configured to penetrate a wall of the pressure-tight container. A seal is arranged around the housing and configured to form an airtight seal between the housing and the wall. A pressure controller is arranged in the housing and configured to provide a controlled transfer of a material between the housing and the pressure-tight container through the wall thereby adjusting an internal pressure of the material within the pressure-tight container.

US12385702 - Jig for manufacturing of firearm lower receiver

An improved jig for manufacturing a firearm lower receiver is comprised of a power tool mount; an adapter; a guide plate with plate screws; a rear support with mounting screws; a front support; and at least one of a carriages with at least one locating pin. A guide plate is disposed below the top surface of a lower receiver in conjunction with an adapter. The jig is a universal fitment and includes a bearing to support a rotary tool and at least one guiding feature can be used to facilitate in the guidance of the rotary tool without placing the rotary tool in direct contact with any of the guidance features. A removable locating pin is situated a long the front and rear takedown pin holes of a firearm receiver that is not threaded and is provided with at least one of a pull, string or other handle.
