Abstract: A találmány szerinti berendezés szemes anyagok tárolását oldja meg, minden eddig ismert berendezésnél gazdaságosabb és célszerűbb módon. A tárolónak hegesztett lemezcsikokból összeállított és gyárilag - a horpadást meggátló osztású felhegesztett oszlopokkal merevített, a szállításkor könnyen feltekercselhető héja van. A héj falvastagsága a terhelésnek megfelelően felfelé csökkenő falvastagságú, az utolsó felső lemezcsíkot a kezdő héjelem falvastagságával azonos vastagságú gyűrű zárja le. Az oszloprendszer az alaphoz célszerűen kialakított csuklós rögzítő elemen keresztül nyomatékmentesen kapcsolódik, a terhelésnek megfelelően elfordulhat, miközben a rugalmas tömítőanyag a zárást biztosítja. A hengeres palástot, hegesztett lemezekből öszszeállított, ráhegesztett bordákkal merevített, zártszelvényű gyűrűvel összefogott kúpos tető zárja le, amely a szállításkor szintén föltekercselhető. A héj és a tető kapcsolata a célszerűen kialakított kengyelekkel könnyen és biztonságosan létrehozható. A tároló alapja az anyagkivételtől és a betáplálástól függően számtalan variációban alakítható ki. A kitárolásra leggazdaságosabb megoldás a felülről fogyó kifolyást biztosító szerkezet, mely kombinálható a levegőztetéssel, hűtéssel, illetve fűtéssel. (1 ábra.)  lábra -1-

Title: Process and circuit arrangement for producing mono-, di-, trichloromethyl chloroformiate
Inventor: BERCZES TIBOR
IPC: C07C69/96
Filed: 1987-08-05
Abstract: The invention relates to a process for the preparation of monochloromethyl chloroformate and trichloromethyl chloroformate by photochlorination of methyl chloroformate. According to the process, in a first step at 60-70@C chlorination is carried out until the ester is reacted to at most 50%, then the reaction mixture is separated by rectification and the unreacted methyl chloroformate is fed back into the reactor. The molar ratio in the reactor between ester and chlorine gas is between 3:1 and 2:1. The monochloromethyl chloroformate obtained during the rectification as a bottom product is either drawn off as a final product or completely or partially led into a further photochlorination reactor in which the molar ratio between monochloromethyl chloroformate and chlorine gas is 1:2-1:3 and the temperature 90-110@C. The reaction product is separated by rectification and the head product is fed back into the second reactor, while the trichloromethyl chloroformate formed as the bottom product is led off as a final product. The invention further relates to a suitable apparatus for carrying out the process continuously. <IMAGE>

Title: Mobile collector of solar energy
Inventor: PUTĀNS Henriks
IPC: F24S90/00
Filed: 2010-10-22
Abstract: The invention concerns renewable energy sector, particularly solar energy collectors for individual (family) use where the solar energy is used for water heating. The solar energy collector, warm water accumulation tank and equipment required for device operation are placed on the platform which is equipped with wheels and rest state support, in order to extend operational parameters of the device. The water can be filled in the system through the valve or hopper. After locating the device on the operational place, connecting to the electrical grid and orienting it to the sun, water in the solar collector becomes warmer. Control unit of the circulation pump operation switches on the circulation pump when water temperature in the collector becomes few grades higher than water temperature in the water accumulation tank. Correspondingly, when the water temperature difference decreases, the control unit switches off the water circulation tank. In dependence on the size and power of the solar collector, it is possible to move the platform by physical force or by a mechanical vehicle. To decrease the weight of the device, the absorber and cover of the collector are made of a cell polycarbonate.
