Abstract: A recessed expansion chamber in a gun slide is configured for improving recoil mitigation in firearms. The gun slide is for a pistol firearm with a barrel and includes a recessed expansion chamber. The recessed expansion chamber is positioned forward of the barrel end of the barrel. An expansion chamber opening is included through the gun slide in communication with the recessed expansion chamber. The recessed expansion chamber is configured to allow gases leaving the barrel at the barrel end to expand and be directed out of the gun slide through the expansion chamber opening.

Abstract: The present invention includes a toy with a retractable mechanism capable of transforming its original compact shape into a new entity, comprising: a hollow sphere (1) provided with a cut on the lower part thereof (2), on the upper end a convex protuberance is projected (3), provided with a modified asymmetric cylinder, which reduces its size in the upper end assimilating the neck of the body of the sphere (4), is formed by two hinges (9A, 9B) of plastic material adjoined to cap (5) that includes one or more internal springs within the cap (5) that maintain these hinges (9A, 9B) under tension, wherein when the convex protuberance (3) is pressed it ejects the body (4) and rotates, when the sphere (1) receives a strike or is pressed, an identity different from the initial one is shown.

Abstract: The present invention includes A toy with an extendable mechanism capable of transforming its original compact shape into a new entity without need to manipulate its parts or add new parts comprising: a hollow sphere (1) formed from two caps; an upper hinge (4) at a top of the hollow sphere (1) that connects two symmetrical caps; two protuberances (5) generally centrally located in each of the caps connected to a central internal spring; a circular hinge (6) connected to a spring and the hinges articulate two cylindrical arms (7) that converge in two circular hinges (8) contained within a central casing (9); and a body-shaped part (10) connected to the central casing (9), such that the body-shaped part (10) projects out from the lower part of the sphere (1), and upon being ejected, the caps close automatically with a spring at the upper hinge (4).

Abstract: A collar stay in which the main body attaches to the collar wing and the collar band attachment attaches to the collar band, said main body lying in a different plane from said collar band attachment in such a way as to admit a tie into the space between the main body and the collar band attachment.

Abstract: A stock sheet metal coil is pre-creased such that upon removal of sheet metal from the coil, the resulting sheet metal strip may be easily and accurately bent or formed along the crease, forming flashing, ducting, or like structures of consistent straightness in any desired length up to the length of the coil. For flashing, the crease is typically formed centrally, between the two ends of the coiled sheet metal to form a flashing of the appropriate angle. Multiple creases may be provided to allow the accurate forming of other structures, such as sluices, gutters, or ducts or conduits in any desired length, reducing connections. Accurate forming may be done at the job site by hand bending at a bead or hand pressing over a wooden block or metal base.
