Method for manufacturing a housing enclosing a pyrotechnic load
A method for manufacturing a housing enclosing a pyrotechnic charge and an installation for implementing this method includes inserting a pyrotechnic charge into a charging volume laterally delimited by a rigid cylindrical charging wall and into a lower part by a first element of the housing to be obtained; positioning a second element of the housing to be obtained of cylindrical shape above the inserted pyrotechnic charge and in the extension of the cylindrical charging wall. The second element has a lateral cylindrical wall of the same shape and diameter as the cylindrical charging wall and is able to cooperate with the first element, and jointly translating the second element and the cylindrical charging wall relative to the first element such as to make the second element cooperate with the first element and form the housing enclosing the pyrotechnic charge.
Segment pressing of shaped charge powder metal liners
A shaped charge liner may include a plurality of liner segments for a shaped charge configured to perforate a sidewall of a wellbore upon detonation. The plurality of liner segments may include a tip liner segment comprising a first group of compacted metal powder having a hollow cone shape with a trailing interface end disposed opposite a tip end. The tip liner segment is configured to be disposed in a shaped charge casing of the shaped charge. The plurality of liner segments may also include a base liner segment comprising a second group of compacted metal powder having a truncated hollow cone shape with a trailing base end disposed opposite a leading base interface end. The trailing base end has a larger diameter than the leading base interface end, and the base liner segment is configured to be disposed at least partially within the shaped charge casing.
CARTRIDGE LOADING PROCESS FOR BUFFERED SHOT SHELL LOADS
Disclosed are processes for loading a cartridge such as a shot shell with a shot load and a charge of buffer material. The processes employ a tube that is coaxially aligned with the axis of the cartridge case or shot cup, the tube having an outer diameter that closely fits into the inner diameter of the cartridge case or shot cup. Shot and buffer material are loaded, the leading edge of the tube is inserted to a sufficient depth to cause at least a portion of the shot load and buffer material to rise into the inner volume of the tube, and the tube removed. The insertion-removal cycle effects the efficient mixing of the shot and the buffer material and can be repeated as many times as desired.
Non-destructive inspection methods and systems
A non-destructive inspection method that comprises obtaining one or more images corresponding to an X-ray, scanning electron microscope, or CT scan of an object, assigning numeric values to pixels of the images, comparing the numeric values to reference numeric values, and identifying an anomaly in the object based on the comparison. A non-destructive inspection system that comprises at least one processor, a memory in communication with the processor and storing instructions that causes the processor to obtain an image corresponding to an X-ray, scanning electron microscope, or CT scan of an object, assign numeric values to pixels of the image, compare the assigned numeric values to reference numeric values, and identify an anomaly in the object based on the comparison.

Initiating device and method for manufacturing such a device
An initiating device including at least one detonator, at least one booster charge and an action charge. The at least one booster charge is arranged such that, at the action charge initiates, the booster charge is free from disturbing edge effects that can have a disturbing effect on the action charge. A booster casing in which the booster charge is disposed is configured with a rear cylindrical part having a diameter D.sub.1, a front conical part delimited by a first circular limit face having the diameter D.sub.1, and a second circular limit face having a diameter D.sub.2, wherein the two limit faces are plane-parallel at a distance H.sub.1 from each other, wherein H.sub.1/D.sub.2 lies within a range 0.5-1.5. Also, a production method for producing the booster charge.
Method of making a multilayer article
A method of making a multilayer article includes providing a mold defining a first cavity with a removable element therein; placing a first particulate component in the cavity; compressing the component along a first axis in a first compression step to form a first layer of the article; removing the element from the cavity after formation of the first layer; placing one or more additional particulate components in the mold; compressing the one or more additional particulate components along the first axis in one or more additional compression steps after removal of the element to form one or more additional layers of the article, wherein the first layer meets one of the one or more additional layers along a first interface substantially parallel to the first axis and the first layer meets one of the one or more additional layers along a second interface substantially perpendicular to the first axis.
