Title: Helical compression spring
IPC: F16F1/06
Filed: 1989-01-10
Abstract: In order to be able to use a helical compression spring (1, 2) as a locking spring, as an individual wire spring or a multiple wire spring in machine guns, it is proposed by the invention to select a spring material variant for matching which is as good as possible between a mandrel (16) or a case (17) as the guide element and the helical compression spring (1, 2). If a normal spring material is used, a major increase in the service life can be achieved by coating the wires (3, 7, 8, 9) with an age-hardening (precipitation-hardening) spring material on a cobalt-nickel-chromium base with titanium and aluminium additives, or a titanium nitride coating by means of sputtering. If the base material which is used for the wires (3, 7, 8, 9) of the helical compression spring (1, 2) is made of an age-hardening spring material on a cobalt-nickel-chromium base with titanium and aluminium additives, the coating of the wires may optionally be omitted. In addition to good mechanical properties, the helical compression spring (1, 2) has good insensitivity to stress cracking, in consequence good vibration damping and a considerably improved life. <IMAGE>

Title: Safety device
Inventor: VOLCKART PETER
IPC: F42C15/40
Filed: 1989-02-11
Abstract: A safety device for the fuze of a projectile comprises a rotor (16) having a detonator (18) which can be moved from a safe position into an armed position. The rotor (16) is driven by a spring (22) which is stressed for the first time by a motor (44), via an intermediately connected control disc (54) and a spring core (24), when specific signals are present. In the event of rotation of the control disc (54) and of the spring core (24) through a specific angular magnitude, a mechanical detent in the form of an arming bolt (32) is unlocked, as a result of which initial pre-arming of the rotor (16) takes place. In order finally to release the rotor (16) for movement by means of the spring (22), an electrically operable detent must additionally be unlocked via a release magnet (42). After this, the rotor (16) can be moved into the armed position via the spring (22) (Fig. 9). <IMAGE>
