  • Patent number: 5540819
    Abstract: There is proposed a water treatment method by causing the water to be pured to flow through a first and a second compartments arranged in succession in an electrolysis cell divided by a permeable membrane into said first and second compartments. Each of the compartments accomodates an electrode, one of them being an anode, and the other--a cathode. Direct electric current is then passed through the water between the anode and the cathode, the current value being determined from the following equation:I=K.times.(C).sup.1/4 .times.Q,whereinI is the current amperage (A),C is the feed water mineralization equal to 0.1-1.5 g/l,Q is the water flow rate (1/hour), ##EQU1## the I/Q ratio being comprised within from about 110 to about 220 Coulomb/liter. The water is caused to flow successively from the anode compartment towards the cathode compartment. Once the water is discharged from the cathode compartment, it is subjected to filtering by passing the water through a bed of a porous carbonaceous material.

  • Patent number: 4615474
    Abstract: An instrument for ligating bone tissues of ribs and clavicles with metal staples includes an anvil body rigidly connected to a staple driving body which accommodates a staple pusher. The latter is mounted for reciprocation in relation to the anvil body. A hook with an anvil is mounted on the staple driving body for reciprocation in relation to the latter. The staple pusher and the hook are driven by relatively movable assemblies composed of a nut and a screw, as well as cams which translate longitudinal motion of the screws in relation to the anvil body into transverse motion of the staple pusher and the hook relative to the anvil body.

  • Patent number: 4596351
    Abstract: A surgical stapling apparatus, comprising a thrust case incorporating a lengthwise groove. Said groove accommodates a magazine containing staples, and drivers of the staples, and a wedge interacting with said pushers and seating on a carriage supported in guides running along said staple case. A surface of said wedge interacting with said drivers is curvilinear, with lines tangent to the generatrix thereof and a travelling direction of said wedge located so as to constitute an angle varying gradually from 45 deg to zero between a front part of said wedge and the back part thereof in the direction of the wedge travel during stapling procedure.

  • Patent number: 4492226
    Abstract: A device for uniting bone fragments comprises a rectilinear body and a contrivance for fixing it in the coapted bone fragments. The contrivance for fixing the body in the coapted bone fragments is formed by thrust members being the portions of the body located at the opposite ends thereof and having holes coaxial with the body; the holes being shaped as frustums of cones facing with their greater bases the ends of the body, and having annular grooves in the wall thereof, and cone-shaped inserts with annular ridges adapted to be introduced into the conical holes for wedging apart the body. The body has longitudinal through slots within the zones of the holes. The length of the device is less than the total length of the coapted bone fragments so as to be located fully within the bone tissues.
