Examples of Using IMPINGEMENT in a Sentence

• The Hakim system is adjustable by use of a special tool and is a simple, direct impingement type whereby the flow of gas impacts directly on the front face of the bolt carrier, propelling it to the rear, which unlocks and moves the bolt as it does so.
• The first experimental rifle using a direct impingement system was the French Rossignol ENT B1 automatic rifle followed by Rossignol's B2, B4 and B5.
• This impingement can cause pain in both upper and lower limbs and a numbness or tingling sensations in the hands and feet because the nerves are supplying sensation to their dermatomes.
• The MAS direct impingement design reduced the number of bolt moving parts to only six: the bolt carrier, then the rear locking tilting bolt which carries the extractor, the ejector and the firing pin, and lastly the recoil spring.

• They can include infection, dislocation, limb length inequality, loosening, impingement, osteolysis, metal sensitivity, nerve palsy, chronic pain and death.
• The subtleties involved in ArmaLite's patent on the gas system significantly diverge from classical direct impingement; upon firing, the pressurized propellant gasses exit the barrel via the gas port and travel the length of the gas tube, but instead of simply applying the inertia necessary to cycle the weapon directly to the bolt carrier, the gas is funneled inside the bolt carrier wherein the increase in pressure results in the bolt itself acting as a piston, forcing the bolt carrier away from the barrel face.
• Another potential contributing cause is impingement syndrome, the most common non-sports related injury and which occurs when the tendons of the rotator cuff muscles become irritated and inflamed while passing through the subacromial space beneath the acromion.
• This contrasts with conditions such as shoulder impingement syndrome or rotator cuff tendinitis in which the active range of motion is restricted but passive range of motion is normal.
• This loss of height causes laxity of the longitudinal ligaments, which may allow anterior, posterior, or lateral shifting of the vertebral bodies, causing facet joint malalignment and arthritis; scoliosis; cervical hyperlordosis; thoracic hyperkyphosis; lumbar hyperlordosis; narrowing of the space available for the spinal tract within the vertebra (spinal stenosis); or narrowing of the space through which a spinal nerve exits (vertebral foramen stenosis) with resultant inflammation and impingement of a spinal nerve, causing a radiculopathy.
• The design is based on the AR-15, M16 and C7 rifles, but has a unique semi-direct gas impingement system and a folding stock option.
• Although the McDermitt volcanic field on the Nevada–Oregon border is frequently shown as the site of the initial impingement of the Yellowstone Hotspot, new geochronology and mapping demonstrates that the area affected by this mid-Miocene volcanism is significantly larger than previously appreciated.

• In addition, the proposed deeper dredging required to support post-Panamax containership vessels threatens shoreline integrity of Cape Fear coastal communities (Oak Island, North Carolina) and (Bald Head Island, North Carolina) as well as threatening the integrity of the fresh water aquifer (required for potable water throughout the region) that runs immediately below the existing Cape Fear River seaway and would be destroyed by seawater impingement if the specified dredging depths occurred.

• Various methods are used for sampling exhaled breath aerosols, such as filters, impactors, impingement filter, or electrostatic precipitators.
• Shoulder impingement syndrome is a syndrome involving tendonitis (inflammation of tendons) of the rotator cuff muscles as they pass through the subacromial space, the passage beneath the acromion.
