Improvement is that na) the acid contg. nitrous cpds. from the denitration zone, which precedes the tower supplied with (II) in the SO2 processing zone on the gas side, is heated above 60 degrees C by indirect heat exchange (with the acid leaving this zone) before contact with the gas stream, and (b) the dwell time of the gas between the denitration zone outlets and the inlet to the first tower of the (I) absorption zone is 30s at concns. of >=5 vol.% SO2 and >=10 vol. % O2 in the gas entering the denitration zone and max. Zmax (in s) at lower SO2 and O2 contents, where Z max = 1500/SO2.O2 (in which SO2 and O2 are the SO2 and O2 contents of the gas entering the denitration zone in vol.%).

Title: Inflatable submersible buoy of fibre reinforced plastic - has automatic buoyancy control by hydrostatic valve in centralised air supply (NL 22.3.78)
IPC: B63B/
Filed: 1977-09-27
Granted: 1985-06-26
Abstract: The inflatable submersible buoy made of fibre reinforced plastic is for use in lowering or raising objects to or from the sea floor. From each buoy a pipe connects into a valve unit (18) with further connections to a centralised air supply (18b) and exhaust (22). A spool valve (53) in the unit can connect the buoy to either supply or exhaust, or seal it off. The valve position is controlled by a spindle (49) connecting it to a diaphragm (48) with one side (50a) under ambient and the other (50b) under buoy internal pressure. Internal passages (47, 60) admit the pressure. A helical spring (58) bearing on the valve supplements ambient pressure on the diaphragm. Spring strength is so chosen that the valve is closed when the buoy plus load have slightly negative buoyancy.

Title: Electric arc furnace for steel smelting

IPC: C21D/
Filed: 1983-05-24
Granted: 1987-07-01
Abstract: A test window (45) is defined (TEST X, TEST Y) which surrounds a window (X Clip, Y Clip) (the clip window) within which it is desired to render graphical images. Objects are then tested (47) to see if their vertices X0-X3 Y0-Y3 are outside the test window. The utilisation of this test window allows for a performance optimisation to be made between processing of a clipped object by a hardware based graphics subsystem or by graphics software executed by a general purpose CPU which also interfaces to the graphics display. By properly defining the test window size relative to the clip window, objects which fall totally within the test window, will be rendered faster by the graphics subsystem rather than deferring the object to graphics software. Objects with vertices that fall outside the test window would be deferred to graphics software to render.

Title: Piezoelectric generator excited by accelerated magnets
Inventor: KLEIVA ARŪNAS
IPC: H01L41/00
Filed: 2021-03-02
Abstract: The invention relates to micro-power generators using a piezoelectric effect. It is a piezoelectric vibration energy harvester, having an increased harvesting efficiency and stability under low frequency (<10 Hz) oscillations. The generator comprises a housing (1), a cantilever-type piezoelectric transducer (2) with a magnetic mass (3), and a special system of accelerated magnets. The accelerating magnets (13), under external vibrations and inertial forces, move in special beds (12) of the housing (1), and via magnetic interaction accelerate the driving magnets (9) in a non-contact manner. The array (9) comprises at least 2 magnets (10) separated by nonferromagnetic gaskets (11). Due to the accelerating magnets, the array (9) slides at nearly constant speed, interacts with the magnetic mass (3), deforms the transducer (2) thereby initiating its free high-frequency oscillations. The generator is applicable and efficient under low-frequency excitations such as biomechanical oscillations, e.g. generated by limbs of an actively moving person.
