Applied force of axial tension is reduced over time and/or crack growth (crack propagation). As a result of strain energy in material of fibre is released to form a single plane with optical quality surface does not require polishing. On chipped end of optical fibre is formed essentially flat optical surface of an improved optical quality.EFFECT: enabling breaking of optical fibre so as to minimise light loss when fibres are installed in series.20 cl, 5 dwg
FIELD: personal hygiene items.SUBSTANCE: invention relates to systems for shaving, namely, to design of a razor cartridge. Cartridge (1) includes body (2) with installed in it one or more blades (3), wetting part (5), containing at least 50 % of lipophilic materials by weight of the wetting part located in the body and having first surface (6) contacting with skin and lubricating part (8), containing at least 20 % of lubricants by weight of the lubricating part located in the body and having second surface (9) contacting with skin. Ratio of the first surface area to the second surface area constitutes from 1:5 to 5:1. Lubricating and wetting parts are located on one or on both sides of one or more blades.EFFECT: higher quality of shaving.19 cl, 13 dwg, 2 tbl, 1 ex
FIELD: nuclear engineering.SUBSTANCE: invention relates to means intended for use in nuclear engineering in order to prevent emergency situations by electric circuit break. Device comprises the following components installed in the body; an actuator made in the form of a cutting tool, a trigger mechanism, which is made in the form of heat-sensitive elements of alloy with shape memory, arranged on the piston at the end of which there is fixed a spring-loaded cutting tool. Body is rigidly fixed on the base and closed by a cover. In the base there is a groove accommodating an overcut electric bundle and a hole for passage of the cutting tool. Base is rigidly fixed on a support plate, and on the walls of the body and cover there are holes for heat supply. Heat-sensitive elements are made in the shape of plate parts. Cutting tool can be made of non-conducting material.EFFECT: invention increases reliability of device triggering.3 cl, 3 dwg
FIELD: mechanical engineering.SUBSTANCE: invention may be used for punching holes in body parts, in particular in surfacing for installation of parking sensors or headlamp washers therein. Body part is placed in the working position, while a punch is kept over a distance at a standstill. At first, the punch is moved for doing the first stroke in the direction of the working position, in order to locate it near the part. Next, the punch is moved with a mover to punch the part. Punch movement for the second stroke is performed at the rate not exceeding 10 mm/sec and less than the rate of the punch movement for the first stroke. Punch actuating cylinder coupled with a force reduction mechanism is used for the second punch stroke. Punch actuating cylinder is isolated from the mover.EFFECT: possibility to obtain high quality holes using a standard actuating cylinder for the punch movement.10 cl, 8 dwg
FIELD: machine building.SUBSTANCE: invention relates to jet processing of materials. Method comprises generating a processing jet supplied from a nozzle to machined workpiece. Fluid medium used is molten fusible alloy, hydrostatic pressure of which is increased before forming processing jet. Method includes cooling processing jet of said molten alloy to its fractional crystallisation. Collecting partially crystallised spent molten alloy with particles of machined workpiece, is converted into liquid phase is separated particles of processed workpiece from melted alloy and latter is supplied to input of fluid medium circulation.EFFECT: broader technological capabilities.2 cl, 1 dwg
