The feeding tube (28) has a free end and a hole (46) in the side wall near the free end.EFFECT: provision of possibility to adjust the internal pressure by reducing the liquid container internal volume due to the fluid pumping off without the pump complication.14 cl, 18 dwg

Hand-held pumping device // 2621099
FIELD: engines and pumps.SUBSTANCE: hand-held pumping device comprises a head of the peristaltic pump and a container for the liquid to be fed. The pump head comprises a rotatable peristaltic pumping element and a flexible tube to ensure the feed, interconnected to the inner part of the container via the fluid medium. Launching gear actuated by a finger is positioned with the possibility of putting the peristaltic pumping element in motion when it is actuated, so that the peristaltic pumping element rotates and transfers the fluid medium through the tube to ensure the feed. The pump head comprises an opening for the thumb passing through it and positioned in an area around which the peristaltic pumping element rotates during actuation.EFFECT: pumping device and pump head can operate without risk of power boot rupture or thumb injury or with a reduced risk of this, and are also ergonomically advantageous.14 cl, 19 dwg
ethod for producing homogeneous matted coatings by means of radiation curing // 2621098
FIELD: chemistry.SUBSTANCE: method for producing matt and scratch-resistant coatings is carried out under the influence of actinic radiation on coating systems containing activated double bonds during radical polymerization. According to the method for producing matt coatings, a means curable under the radiation influence is applied to the substrate as a coating. The coating is irradiated with ultraviolet light with a wavelength of ≥200 nm to ≤420 nm at a radiation dose of 25 to 120 mJ/cm2. The resulting coating is irradiated with ultraviolet light with a wavelength of ≥120 nm to ≤230 nm. Thereafter, the coating is subjected to final curing by actinic radiation. Moreover, substrates to which the coating is applied by means of above method are proposed.EFFECT: providing the possibility to create a simple method for producing uniform deeply-matted coatings suitable in case of coatings curable under the influence of radiation, with the layer thickness above 20 microns.11 cl, 4 tbl
Kochetov's packed scruber // 2621096
FIELD: machine engineering.SUBSTANCE: packed scrubber comprising a housing with connections for dusted and cleaned gas, an irrigation nozzle device, support grids, between which the nozzle is located, and a device for discharging the sludge. The nozzle is made of a toroidal shape having a section of a circle, in which the blind recesses are made, the nozzle of the irrigation device is made with a perforated spray disk and comprises a cylindrical housing with a fitting having a cylindrical hole connected with a diffuser, and an atomizer is connected to the housing by means of three spokes, made in the form of a perforated disc, the disc of the nozzle atomizer is formed by two surfaces of the spokes with the elements of the propeller type arranged radially and by form can be made straight or curved, the atomizer is made of hard material, tungsten carbide. The housing of the nozzle element is made in the form of three hemispherical surfaces connected to each other with a gap by means of a fastening element through the ring-type spacer elements, and the elements increasing the contact area of the flow with the nozzle are made in the form of corrugated elements located with the gaps relative to the hemispherical surfaces of the nozzle element housing. Hemispherical element surfaces of the nozzles are made perforated.EFFECT: improving the efficiency and reliability of the dust collection process, reducing the metal-intensity and vibroacoustic activity of the device in general.6 dwg
Shower device // 2620436
FIELD: satisfaction of human life necessities.SUBSTANCE: shower device includes a showerhead body (2), containing a showerhead disc (7) and a plurality of outlets (8, 8a). The outlets form several groups. The shower device also includes a water pipeline, extending from the inlet fitting (3) into the showerhead body (2). In addition, the shower device contains at least two chambers (12, 21), which are formed in the showerhead body (2). Two chambers have a parallel fluid connection with the inlet fitting (3) by means of the water pipeline 5, 14. At least one chamber (21) is designed exclusively for the water supplying to one of several outlets groups. Each chamber (12, 21) is designed to supply water to at least one of several outlets groups. Two chambers are located sequentially behind the showerhead disc in the showerhead body (2).EFFECT: provision of the most uniform distribution of the output jets over the entire surface of the showerhead disc, in such a way that, in case of different jets possible switching, the overall appearance has the smallest possible changes.13 cl, 8 dwg
