A parachute flare igniter assembly includes a novel safety for arresting the motion of a slider (116) when subjected to external forces, but allows slider (116) motion when subjected to intended cable actuation forces. The igniter safety includes a housing(112), a slider (116), a cable (130) and a sleeve (102). The slider (116), connected to the cable (130), is slidably received within the housing (112). The cable (130) moves the slider (116) by applying a cable force conventionally obtained by actuation of a parachute associated with the flare and connected to an end of the cable opposite an end connected to the slider. The sleeve (102) is connected to the cable (130) and is disposed between the housing (112) and the slider (116), so that the sleeve will arrest the slider with respect to the housing when the cable force is not present. A flare and a method of providing a safety in an igniter assembly is also provided.

COMPACTION DEVICE FOR FIBER PLACEMENT USING INTERDEPENDENT SEGMENT TRAVEL
A method and system for a fiber compaction device with interdependent segment travel is described. A compaction device structure supports a series of individual interdependent segments including a compaction surface. Each segment also includes an opening in which a presser member can be located. The presser members consist of either an elastomeric bladder filled with an incompressible fluid or individual pistons that are manifolded together with a fixed volume of incompressible fluid. The presser members create an interdependence in segment positions such that if one or more segments are displaced the others move to balance the segment positions. Having a fixed volume of incompressible fluid allows the segments to work interdependently, thus guaranteeing that the average section position will be the nominal position and eliminating the need for a fixed center section. The segments can conform to complexly shaped part surfaces and apply a uniform pressure against the entire surface to better compact material being drawn through the fiber compaction device.
Electronic time delay apparatuses and methods of use are disclosed. An explosive or propellant system, which may be configured as a well perforating system includes an electronic time delay assembly comprising an input subassembly, an electronic time delay circuit, and an output subassembly. The input subassembly is activated by an external stimulus, wherein an element is displaced to activate an electronic time delay circuit. The electronic time delay circuit comprises a time delay device coupled with a voltage firing circuit. The electronic time delay circuit counts a time delay, and, upon completion, raises a voltage until a threshold firing voltage is exceeded. Upon exceeding the threshold firing voltage, a voltage trigger switch will break down to transfer energy to an electric initiator to initiate an explosive booster within the output subassembly. The explosive booster provides the detonation output to initiate the next element explosive or propellant element, such as an array of shaped charges in the well perforating system.
