20110203090 | BALLISTIC ENHANCED BATTERING RAM - A ballistic battering ram device that uses gun powder to produce a striking force. The ballistic battering ram includes a hollow casing, a bolt piston housing housed within the hollow casing, a bolt housed within the bolt piston housing and configured to slide back and forth, and a firing pin attached to the bolt and configured to strike the primer on the explosive casing. When the user strikes the door with the ballistic battering ram a front plate makes contact with the door pushing the bolt piston housing towards a chamber piston. Simultaneously, a retention pin timing spring pushes against a retention pin withdrawing the retention pin from inside the hollow casing. This action may allow the chamber piston to move backwards after firing which may be important for recoil management. | 08-25-2011 |
20120000047 | PROPELLANT ACTUATED HINGE REMOVER - A hinge remover has a thick cylindrical base with a central opening and a flange, a hollow cylindrical wall upon a yoke, and two spaced apart shoulders upon the yoke. The shoulders receive a door pin. The wall receives a head upon a spring and has two diametrically opposed recesses for ball bearings. The central opening admits the head extending opposite the yoke. The central opening narrows and forms a chamber for a propellant. The base has a radial aperture that opens for an igniter that contacts the propellant. During assembly, the head compresses upon the spring against the yoke revealing the recesses to receive the ball bearings as the head eases inwardly. Upon combustion of the propellant, the head retreats towards the yoke, the ball bearings fall, and the yoke separates from the base. | 01-05-2012 |
20120073101 | PULLING PLIERS METHOD AND APPARATUS - Pulling pliers are provided. The pulling pliers include a pair of pliers having a set of jaws; and an attaching point connected to a jaw of the pliers for attaching a slide hammer mechanism. A method for pulling using pulling pliers is provided. The method includes gripping an object with the pliers; locking the pliers in a gripping position; and actuating a slide hammer attached to the pliers. | 03-29-2012 |
20160067852 | APPARATUS FOR REMOVING PIN FROM TARGET LOCATION - An apparatus for removing a pin from a target location is described. The apparatus includes a rod; a clamp that includes multiple arms and attached to a one end of the rod; a sleeve coupled to the rod and adapted to enclose the clamp, where the arms of the clamp are pushed towards each other to engage with a pin in the enclosed position. The apparatus further includes a clip member to couple with the rod for removing the pin from the clamp by disengaging the clamp from the sleeve. The clip member includes a first arm coupled to a second arm via a pivot member, the clip member being adapted to couple to the rod between the sleeve and a hammer. The hammer is coupled to the rod and adapted to strike a force on the clip member to disengage the clamp from the sleeve. | 03-10-2016 |
