A Ported Press Adapter Expand Mandrel System (PPAEMS) includes a Ported Press Adapter (PPA) as a significant advancement beyond the Expand Mandrel Window Riser (EMWR) by adding multiple radial holes to provide increased light intrusion, full 360 visibility, and balanced stress distribution with a pattern of port holes, slots, or other openings. Additional clarity is provided by an ancillary light source directed into the working area. Utilizing a small diameter Mandrel Holder (MH) allows for a wide range of mandrel diameters for installation in tight working areas (coax and progressive presses) and improves axially precision with a fine thread pitch.

The invention describes a holding device (12) for holding and releasing a tensioning means (14) of a vehicle safety system. The holding device (12) includes a pyrotechnical actuator assembly (24) for holding and, in terms of signals, specifically releasing the tensioning means (14), wherein the actuator assembly (24) comprises a plastic base (26) in which a pyrotechnical unit (28) including a propelling charge and an igniter (30) is accommodated and held, wherein the pyrotechnical unit (28) has a rear side (36) and an opposite front side (38), and a tensioning means holder (40) which is adjacent to the front side (38) of the pyrotechnical unit (28) and covers the same and which is detachably supported on the plastic base (26). The holding device (12) additionally includes a reinforcing element (58) which is supported to be axially movable between a first position and a second position, wherein the reinforcing element (58) in a second position is disengaged from the tensioning means holder (40) and in a first position is at least partially accommodated in the tensioning means holder (40) and mechanically reinforces the same. Furthermore, an airbag module (10) is described.

A projectile for muzzle-loading firearms is made completely from a non-lead metal or alloy. It includes a pair of grooves to incorporate O-rings around a circular cylinder. A threaded well may be bored into the forward facing of the cylinder to facilitate insertion and/or removal of the projectile from the barrel via a cooperating ramrod. The projectile is then wrapped in a cloth patch to cover the sidewalls and bottom facing of the cylinder. A method of forming a plurality of the projectiles from standardized bar stock is also contemplated.

The invention concerns a blasting system (1) configured for explosive material charging in a borehole (3). The system (1) comprises a detonator support device (5) configured to be inserted into the borehole (3) by means of a charging hose (7); a main body (9) of the detonator support device (5) comprises a channel (8) oriented along a main body centre line (CL) extending along the borehole extension during said explosive material charging; an openable cover device (14) covering the channel (8) is configured to come into contact with the charging hose (7) in motion for pushing the main body (9) along the borehole (3), wherein the charging hose (7) in motion is configured to open the openable cover device (14) whilst a stopping arrangement (13) stops the main body (9).

The invention also concerns a method of explosive material charging in a borehole (3) by means of the blasting system (1).

Progressive ammunition press system, components thereof, and associated methods. The press system may include a press control system integrated with the press. The press may include a case carriage including a case carrier supported by a bearing. Case retainer gates may be provided for retaining cases in the case carrier. A bullet feeding system can be arranged to permit bullet feeding and seating in a single station of the press. A primer feeder can be self-contained, gear-driven, and/or recirculating.

A method and apparatus for igniting a power charge in downhole wellbore using an ignition propellant mixed with a main propellant, the ignition propellant may be concentrated at the first end of a housing where it is the majority propellant and then gradually mix with the main propellant, transitioning to a majority of the main propellant.

Provided is ammunition decapping apparatus 10 comprising a decapping platform 12, a case receptacle 14, a die gantry 40 arranged over the decapping platform 12 and including a reciprocating die mount 42, and a case feeder 46 configured to operatively feed a case upright onto the decapping platform 12. Also included is a case urger 48 configured to urge a case fed from the case feeder 46 into the case receptacle 14, and an actuator arrangement 50 configured to actuate the case urger 48 and die mount 42 so that a case is fed into the decapping receptacle 14 and a die 44 mounted in the die mount 42 is able to decap the case.

A propellant container for a perforating gun includes a lower cap, one or more pieces of propellant positioned within the lower cap, wherein at least one of the one or more pieces of propellant defines one or more through-holes, and an upper cap matable with the lower cap to secure the one or more pieces of propellant within the lower cap. A filler material is present within interstitial spaces between the one or more pieces of propellant.

Embodiments of the invention relate to a drive system for armored electric vehicles and a method for its operation in event of a fire of the traction battery.
