Abstract: FIELD: firearm, applicable in production of automatic weapon with various rate of fire. 
     SUBSTANCE: the moving barrel acting on the arms of the joint lever accomplishes kinematic coupling to the breechblock assembly. As soon as the larger arm of the rear transversal surface of the stepped lug of the breechblock assembly the bore gets opened. The joint lever at sliding of its larger arm on the longitudinal working surface of the breechblock assembly lug the barrel is stopped, when the barrel recoil is completed, preventing its reverse motion, up to the completion of the recoil of the breechblock assembly and the coincidence of the cylindrical working surfaces on the lug of the latter and the lever larger arm. The ammunition feed mechanism linked with the moving barrel performs feeding of the successive ammunition to the extractors of the breechblock assembly. After the barrel stops in the initial position the counterrecoil of the breechblock assembly is completed under the action of the return spring, which rams the successive ammunition to the bore and locks it by coupling of the barrel and the breechblock assembly. The barrel of the automatic firearm is installed in the guides of the box for recoil backwards and is provided with a spring. The larger arm of the joint lever is made in the form of a cylindrical surface. Lugs are made on the barrel and the breechblock assembly, on the barrel-for engagement with the smaller arm, on the breechblock assembly - for engagement with the larger arm. The stepped lug on the breechblock assembly has longitudinal and cylindrical working surfaces on the middle step, and the front and rear transversal working surfaces - on the extreme steps. 
     EFFECT: simplified construction of the weapon and improved its dimensional and mass characteristics.

Granted: 2006-10-20
Abstract: FIELD: medicine. 
     SUBSTANCE: method involves taking specific anterior capsule properties and subjacent lens layers state in various congenital cataract forms. Full cataracts having nebulous anterior capsule are treated with pulses of 1.2-2.0 mJ and continuous circular capsulorhexis with YAG-laser beam focused directly on the nebulous capsule. Atypical cataract with inhomogeneous anterior capsule destruction and underlying calcificates being the case, pulses of 0.8-2.0 mJ are used. The anterior capsule is opened in maximum nebulosity intensity places of the anterior capsule and subjacent calcificates with laser beam focused thereon. The continuous full circular capsulorhexis is finished by focusing on laser perforates periphery. Full and zonular cataract with transparent anterior capsule and cloudy subjacent layers being the case, pulse energy of 2.2-2.5 mJ is applied. These cases involve opening the anterior capsule with shock wave of YAG-laser radiation focused on nebulas in subcapsular layers. The full circular capsulorhexis is finished in these cases with focusing on laser perforates periphery. Pulse energy of 2.3-3.5 mJ is used in children having zonular and atypical cataract when the anterior capsule and subjacent lens layers are completely transparent. Gas bubbles are formed in anterior subcapsular lens layers using defocused laser treatment and complete capsulorhexis is carried out with focus set over the anterior gas bubble surface and laser perforate edges. Complete milk cataract being available, laser capsulorhexis is carried out beginning from lower segment from 6 o'clock 12 o'clock position clock- and counterclockwise. 
     EFFECT: enhanced effectiveness in making complete circular incision without overlaps.
