Abstract: Úkolem řešení je výroba čistého siřičitanu
hořečnatého, při kterém se působí oxidem
siřičitým na znečištěnou hořečnatou
surovinu. Způsob řeší využití produktu z
odsiřování spalin. Na vodnou suspenzi, připravenou
z uvedené hcřečnaté suroviny a
obsahující případně rozpuštěný síran a siřičitan
hořeěnatý, se působí plynem, obsahujícím
oxid siřičitý tak, aby konečná reakční
směs měla teplotu nad 40 °C, pH ,nad
3,5, s výhodou 5,5 až 8,5 a obsah siřičitanu
horečnatého nad 0,7 % hmotnosti, s výhodou
4 až 8 % hmotnosti. Poté se z takto získané
reakční směsi oddělí nejpozději před
uplynutím tří hodin kapalná fáze od suspendovaných
nečistot a tento přesycený
roztok siřičtanu hořečnatého se zpracuje
na hořečnatou sloučeninu, např. ochlazením
se oddělí krystalický siřičitan hořeč-
natý. Kapalná fáze získaná po oddělení siřičitá,nu

Abstract: A fluid valve includes a sleeve (12) having inlet and outlet ports (26, 18). There is a stem (16) movable within the sleeve between open and closed positions and having an inlet port (40) and an outlet port (49). The stem inlet port is in communication with the sleeve inlet port and the stem outlet port is movable into registration or communication with the sleeve outlet port to define a path of flow through the valve. A seal (34) is carried by the sleeve and cooperates with the movable stem to close the path of flow. There are means for reducing noise normally attendant to opening the valve which includes a passage (48) in the sleeve directly adjacent the sleeve outlet port. The passage is in communication with the stem outlet port as the stem outlet port initially moves to open the path of flow to divert water and reduce pressure at the communicating outlet ports.

Title: Apparatus for transferring a finely-divided solid material between chambers at different pressures
IPC: F27B15/08
Filed: 1975-05-29
Abstract: Two spaces are provided, one of which is at a higher pressure than the other. A transfer arrangement serves for transferring a finely divided solid material, e.g., a combustible fuel, from one to the other space, usually from the lower-pressure space into the higher-pressure space. This arrangement includes a housing bounding a spherical chamber having two openings each of which communicates with one of the spaces. A spherical body is located turnably in the housing and provided with a blind bore the open end of which can be placed into communication with one or the other of the openings, depending upon the turning of the spherical body. A piston is reciprocable in this bore and can be retracted to draw a quantity of solid material into the blind bore when the open end thereof registers with one of the openings, and can be advanced for expelling the quantity when the open end registers with the other of the openings. A direct communication between the two spaces is therefore reliably avoided at all times.

Title: Anaerobic purification equipment for waste water
IPC: C02F3/28
Filed: 1985-07-23
Abstract: A considerable portion of the gas developed by fermentation in an anaerobic purification equipment for waste water, together with buoyant sludge, is collected by at least one additional collecting system (5), before it may reach the upper part of the reactor. This additional collecting system is fitted at a distance below the collecting system (6) fitted as usual just below the level of one or more overflow gutters (3; 23) for purified water. The additional collecting system (5) has a hydraulic link with one or more rising pipes (7, 7', 27, 32,31) for raising the liquid sludge mixture by gas lift action. The rising pipes discharge into a separation device (8) from which one or more downpipes (9; 29) for returning separated liquid and sludge extend to the lower section of the reactor chamber. As a result of the tranquility at the top and the turbulence near the bottom, a substantial increase of the load capacity of the equipment can be obtained.
