3	Firearm projectile	US11234613	2005-09-23	US07219607B2	2007-05-22	Terrance D. Oertwig
Projectiles for firearms, specifically bullets, are discussed that include a rear thin-walled counter bore. The counter bore is designed to be a first size and shape when the bullet is loaded into the firearm and expand upon discharge of the firearm so as to force the walls of the counter bore into barrel rifling. The expansion may occur through the direct interaction of propellant gases with the counter bore walls, or at least partially indirectly though the inclusion of an expansion plug that is placed at least partially within the counter bore in a manner that the expansion plug can be driven further into the counter bore by the firing action of the firearm.
4	Method and an apparatus for sealing an explosive charge compartment in a shell	US899911	1992-06-17	US5239929A	1993-08-31	Stig Nilsson; Jan Fixell; Klas Larsson
A device and method are provided for sealing off an explosive charge compartment in a shell of the type in which the shell includes a shell case at its forward region and an element which is inserted into said shell case to cover an explosive charge and is provided with an outer annular abutment surface abutting against the inner contour of the shell case. The device includes a strand of sealant compound which is applied at least along an edge of the upper end portion of the element covering the explosive charge and a radially expendable ring which is forced by radial flaring against the sealant compound to straddle at least a joint between the edge of the upper end portion of the covering element and the inner contour of the shell case to accurately follow inner contours of the element and the shell case.
5	Submunition for a spin stabilized carrier projectile	US884141	1992-05-18	US5183962A	1993-02-02	Klaus D. Karius; Armin Eskam; Karl-Heinz Vogt
A submunition unit for a spin stabilized carrier projectile (1), with the submunition unit including an antenna disposed at the nose of its casing (7), and with the antenna (5) being covered by a protective cover (6). The casing (7) and the protective cover (6) are provided with respective axially overlapping collars (8, 9) which are each provided with respective opposed circumferential grooves (14, 15) to form an annular recess to accommodate an elastic securing ring (16). The securing ring, which is normally positioned within the innermost of the circumferential grooves, expands under the influence of centrifugal forces to connect the casing and protective cover together in a form-locking manner.
6	Device for a projectile	US3719339D	1971-02-09	US3719339A	1973-03-06	SIMMONS B; KARSBERG L
A device separable from a projectile arranged to be fired from a rifled barrel. The device includes a unit such as a flare supported by a parachute which is expelled from the projectile a predetermined time after firing of the projectile. The unit is placed in a container which is initially closed at one end by a bottom plate which also constitutes the bottom plate of the projectile and is capable of sustaining the powerful gas pressure generated when the projectile is fired. Upon expulsion of the container from the projectile by a suitable timing and expelling assembly, the container separates into several parts and a brake mounted on the unit is activated by the centrifugal force and causes a slowdown of the unit. The bottom plate which is also subject to the centrifugal force is pivotally connected to the unit by a pivot means which is eccentrically disposed with respect to the lengthwise center axis of the container and thus of the unit. The combined action of the centrifugal forces acting upon the brake and the bottom plate cause the latter to pivot into an angular position in which it is released from the pivot means and is thus ejected out of the linear path of the unit, thereby preventing collision with the same.

A closure ring is disposed in said aft portion, a vent also being provided in said aft portion. The warhead casing is filled with a predetermined level of explosive material. Preferably the explosive composition contain reduced amounts of explosive material and a strong oxidizer. The warhead assembly possesses superior penetration and blast performance, as well as superior Insensitive Munitions characteristics.
12	Separating device for the aerodynamic braking of a body	US458734	1989-12-01	US5054400A	1991-10-08	Jean-Pierre Pineau; Jean-Pierre Frehaut; Philippe Kerdraon
A projectile with rear and front sections able to deliver payloads of submunitions contained inside the projectile after separation of the rear from the front section. The rear section is fitted with an assembly of thin blades. When both sections are assembled, the blades are partially in the rear section and partially in the front section, and when the two sections are separated, the blades spread out. The assembly is such that the length of blade that spreads out is greater than the length of blade that was in the front section before separation of the two section.
13	Projectile base for carrier projectiles	US469590	1990-03-22	US5033388A	1991-07-23	Achim Sippel; Heinz-Josef Kruse; Klaus D. Karius; Michael Primus
In projectile bases (20) for carrier projectiles which are equipped with a cavity (26) on the side facing away from the projectile tail for, for example, a parachute, it may happen that the base plate (23) is axially bent through during firing. This causes the base body (22) to be radially constricted and contact is lost between the rotating band (27) disposed on the body (22) and the gun tube, frequently resulting in a gas breakthrough. To avoid the above-mentioned radial constriction in the region of the rotating band, the projectile base (20) is provided with a base plate (23) which is curved toward the tail of the projectile. The curved configuration of the base plate (23) makes it possible to produce radial widening in the rear projectile base region during firing so as to ensure gas tightness and spin transmission from the rotating band (27) even at high gas pressures.
14	Spin stabilized carrier projectile	US135509	1987-12-16	US4854241A	1989-08-08	Reinhard Synofzik; Rolf Hellwig; Klaus D. Karius
A spin stabilized carrier projectile comprising: a projectile body having a rear end; at least one submunition projectile disposed in, and ejectable from, the projectile body; and a projectile bottom disposed at, and ejectable from, the rear end of the projectile body, the projectile bottom having a side surface facing the submunition projectile and containing a recess, and a folded, expandable deceleration element for reducing the velocity and spin of the projectile bottom upon ejection from the projectile body, the deceleration element including a sheet of material fastened in the recess for producing air resistance, and the deceleration element being deployable from a folded condition to an expanded condition with the aid of rotation of the projectile bottom.
15	Base closure for thinwall carrier projectile	US50417	1987-05-18	US4771696A	1988-09-20	John Smolnik
This disclosure relates to a large caliber, thinwall, cargo carrying, spin stabilized projectile of a type in which cargo is keyed to a projectile base member in order to preclude relative rotation between cargo and projectile during in-bore travel. In particular, the disclosure is directed toward an improved base closure method for the projectile including a method for transmitting in-bore torque through a base closure joint.
16	Device for a projectile	US3724380D	1970-12-16	US3724380A	1973-04-03	SIMMONS B
A flare releasing missile has a casing including the propellant charge and a hollow projectile fitted to the casing and housing a flare and a parachute therefor. The projectile including its bottom plate is lengthwise split and the projectile parts thus formed are held together by a cap fitted upon the bottom of the projectile until the same is fired. Upon firing of the projectile the cap is forced off thereby freeing the projectile parts and thus the flare with its parachute. The projectile parts are thrown out of the trajectory of the flare by the centrifugal force acting upon the parts due to the spin imparted to the projectile by the rifling in the gun barrel.
