Publication number: 20030034102Abstract: An incendiary composition (14) for a fin-stabilized kinetic energy projectile (1), which can be arranged in the tail region of the projectile (1) and, upon impact with a target (13), penetrates the target (13) as a separate unit behind the penetrator (2) of the kinetic energy projectile (1). To reach the objective of a high destructive effect caused by the incendiary composition (14) within a target (13), despite a small volume and a low mass, and to ensure that the incendiary composition is ignited securely by the shock waves generated upon impact, according to the invention, a titanium sponge is used as the incendiary composition (14), with an epoxide resin or a polyester resin used as a binder.Type: ApplicationFiled: August 19, 2002Publication date: February 20, 2003Inventors: Stefan Thiesen, Hendrik Lips, Borngon, Dieter Jungbluth

Publication number: 20030034104Abstract: An automobile tire is so constructed that it produces new tread as the old tread is about worn out. The first method is to mould a filler beneath the tread cavity of the new tire. When the tread is worn down to near an unsafe condition, the filler is removed which exposes new tread height.Type: ApplicationFiled: August 20, 2001Publication date: February 20, 2003Inventor: Jerry Artrip
