  • Patent number: 4876943
    Abstract: To permit single firing in a machine gun by a mechanical method, a trip lever is moved by a control surface attached to the weapon housing during the weapon recoil after triggering a shot. This motion causes the trip lever to disengage a coupling on the crankshaft. Because of this, the trigger plate can return to its starting position by means of spring force, independently of the position of the cocking lever. The recoil breech can then be caught by the trigger in the weapon housing. If the cocking lever is moved back, it again couples because of the spring.

  • Patent number: 4876939
    Abstract: With the device a repositioning of ammunition feeds of an automatic weapon into various feed positions and a secured position is achieved. The selective positioning is achieved by a lever which is pivotally supported alongside a drive shaft and abuts by an integrally formed cam at one end face of a pivoting support part axially against a sleeve which is axially displaceable on the drive shaft. The sleeve is under the biasing force of a spring. The end face of the sleeve biasing toward the pivoting support part of the lever possesses also a cam which is in operative connection with a cam of the pivoting support which upon engagement effects a coupling driving engagement of the lever with the shaft. The mechanism acts to hold the lever of the ammunition feed in a respective position by means of the spring.

  • Patent number: 4457092
    Abstract: In automatic firearms having a caliber in the range of about 20 to 40 mm, so-called "jammed shell casings" are occasionally encountered due to the high cadences during the extraction and ejection of the empty cartridge casings, so that the returning breech mechanism tends to lose the cartridge, and the ejector plunger no longer fully impacts against the casing to be ejected. In order to avoid this drawback a recess arranged in the breech head concentrically to the firing pin is provided along its periphery opposite an extractor claw with at least one projection to assist in the centering and retention of the cartridge casing and which can be adapted to the respective type of breech mechanism. The projection is formed by cutting or non-cutting working. Preferably, two or more such projections are formed which then, together with the extractor claw, form a type of "three-point support" for the cartridge casing during the extraction.

  • Patent number: 4419441
    Abstract: Hydrophobic substances, particularly hydrophobic additive for photographic layers such as couplers may be dispersed in an aqueous medium in a two--or more--stage process using an oil-former. In a main dispersion stage the total quantity of the hydrophobic substance is dispersed in the aqueous medium without oil-former or with only part of the total quantity of oil-former. The residual portion of oil-former is dispersed in the aqueous medium without hydrophobic substance in at least one further dispersion stage preceding or following the main dispersion stage. The oil-former used is preferably a compound or a mixture of compounds selected from triaryl phosphates, dialkyl phthalates, monoesters of .alpha.-substituted succinic acid or of hydrogenated phthalic acids and aliphatic or cycloaliphatic alcohols of at least 10 carbon atoms. The process yields dispersions of improved stability of digestion.
