摘要:
Invention is related to design of a blade of a snow plough. Wear element of the blade of the polugh is placed into elastic encasement, which is attached between metal plates, that are attached to the plough, wherein there are openings in the metal plate for cooling, abutments of the wear elements protruding partly from said openings. These protruding parts are in direct contact with the surrounding environment to cool the blade, that heats up because of the friction when the blade and road surface are in contact.

The invention provides a pivotable and liftable support frame for plough and vehicle, which main element is a bearing beam 2, which can be lifted up-down by lift cylinder 3 and turned to left-right by beam move cylinder 4. The frame of the construction acts as double parallelogram. Namely parallelogram acting in vertical plane is formed by bearing beam 2 and connecting element 5 in cooperation with the plough 1 and fixing mount 6 on the vehicle, parallelogram acting in horisontal plane is formed by bearing beam 2 and turn cylinder 7 in cooperation with the plough 1 and fixing mount 6 on the vehicle. Support frame according to the invention differs in that due to the use of connecting element 5 the support frame maintains feature of traditional "parallelogram" of the snow ploughs, which assures that the raised plough in transport position remains parallel to the ground.

Door frame having a groove for door and for fixing hinges, whereby additionally the frame has a ridge adjacent to the axis of the hinge along the whole length of the frame. The dimension of the ridge is suitable to accommodate the axis of the door hinge between the ridge and the groove of the door frame, the height of the ridge is at least equal to the height of the part of the door hinge protruding out of the door frame surface.
摘要:
A filter material and method for its preparation for separation of hydrophilic substances from environment of various hydrophobic liquids or gases. Such hydrophobic substances can be different chemical and oil products, substances of biological origin (fats, essential oils). Hydrophilic substance can be water, lower alcohols (methanol, ethanol), polybasic alcohols, substances dissociating in aqueous solution (salts, acids or bases). Filter material is in the form of oxygen containing polymer, which microscopic and macroscopic structure forms during polymerization process. More precisely the filter material consists of polyacetal for example polyvinylacetal. Polymeric structure of filter material forms during synthesizing reaction of the polyacetal by the action of the assisting substances taken into reaction medium.

A method and device for connecting electrical and electronic devices into integrated network. The device includes monofunctional computer, i.e. programmable controller and actuator controller, and two information channels or networks. Via the inner network takes place the exchange of information between the programmable controller and the actuator controller. Inner network can be: alternate current electricity network, separate low voltage cable network, radio communication network. Public internet, via which are changed system parameters of the programmable controller via WEB interface and secured information on the object for the system operator. Via the internet into the programmable controller are downloaded software updates from the software service server of the operator and software modules of the new applications of the controller of the effective device. Updating of the nodes and controlling elements of the device are done in real-time.

The invention provides a stuffing containing polyethylene flakes and polyester microfibers, which is used as stuffing for bed clothes, especially pillows. The stuffing containing polyethylene flakes and polyester microfibers is light, airy and flexible, giving the same soft characteristic as down pillow. Provided stuffing is unfavorable environment for bacterial growth, being washable at bacteria killing temperature in domestic conditions. A pillow filled with provided stuffing maintains fluffy, flexible and soft even after washing. The stuffing has no healt adversing impacts, being suitable also for allergics.

The claimed device designed for ultrasonic cracking of hydrocarbon compounds (raw hydrocarbons). The device contains an input system, system for running a cavitation process in introduced raw materials, system for extracting the products of processing, system of technical parameter control. The main part of the input-reactor system is constructed with the possibility to organize a cavitation process in raw hydrocarbons, the acoustic ultrasonic radiators are placed in the cavity of the reactor, vertical mixer (rotary mixer) for providing hydrodynamics of pseudo-liquefied vortex layer of the catalysts inside the reactor, the device for supplying raw hydrocarbons to the reaction zone, the device for mixing raw hydrocarbons and gaseous and liquid admixtures, intermediate vessel and device for selection and extraction of target product, rectifying column, system for controlling, stabilizing and registering thermodynamic parameters of processes occurring in the reactor. The device is additionally equipped with a catalyst placed in the container constructed as a basket with the perforated upper and lower bottom and placed in the reactor in the zone of a developed cavitation flow (stream) of the mixture consisting of raw hydrocarbons, gaseous-liquid admixtures and vortex pseudo-liquid layer of the catalyst, including the device for changing (regulating) rotation speed of the mixer (rotary mixer) installed in the lower part of the reactor of the device, device for supplying hydrogen-bearing substance and mixing them with raw hydrocarbons. The casing of the reactor is built out of non-magnetic steel with the possibility to vertically install the prolonged cylinder (H>D) and is equipped two end covers installed in the casing of the reactor with the possibility to provide vacuum density (air tightness) with the upper end cover having holes for installing acoustic ultrasonic radiators in them and the lower one having holes for installing devices intended for supplying raw hydrocarbons, hydrogen-bearing substances to devices where they undergo mixture process. The vessel for the catalyst is located in the upper part of the reactor of the device and is built with perforation holes in the upper and lower bottom. As a catalyst one uses a substance chosen from granules of intermetallic mixture that includes particles of nickel, palladium, platinum, corundum, silica and particles of other metals and oxides possessing higher chemisorptive traits. Installation provides the increase of efficiency thanks to tying (stabilization) of free hydrocarbon radicals generated during cracking and, thus, preventing recombination of initial recombination of raw hydrocarbons. The performance of the device provides information on structural parametric identification of mathematic model used for defining optimum modes for processing raw hydrocarbons.

This invention concerns watertight ready-made or foldable storage bag suitable for preservation of items with various size and shape and protection of items against flood hazards. Bag of the invention includes in preferred embodiment the lower part in the main shape of cuboid made of watertight material, and the upper part, which upper edge is watertightly sealed with methods known from technical level. The bag of preferred embodiment is folded from planar form with suitable shape immediately before the need for preservation of the item, which is especially useful for space saving in case of large items. For smaller items the bag may be pre-folded, so that upon necessity the preserved item can be placed into it, closing the bag watertightly with its upper part. Dimensions of the bag may vary and depend on the dimensions of the item placed within. In this alternative option lower and upper parts of waterproof bag are separate parts, so that the lower part ensures complete watertightness of the item from below and from the sides, and upon flood situation also floatability of the item, while the tent of upper part ensures watertighness of the item against precipitation from above.
