Patent CA-2233303-A1 (CA)
Inventor: KIRKBY ROBERT HOWARD
IPC: H04L27/26
Filed: 1996-10-07
Abstract: Multiple carriers are generated, modulated by data to be transmitted, as shown by oscillators (2-5) and modulators (21, 22, 31, 32, etc.) (or using Fourier transform techniques). They follow two paths. One path via adder (81) takes a set of carriers at integer multiples of a windowing frequency (f), where the odd carriers have some reference phase and the even carriers are in phase quadrature. The other path via adder (82) takes a second set of carriers, again at integer multiples of the windowing frequency; here the even carriers have the reference phase and the odd carriers are in phase quadrature. In the first path the signal is multiplied at (91) by a windowing function with a period equal to the reciprocal of the windowing frequency, whilst in the second path the signal is multiplied at (92) by a similar function which is time-shifted (by a delay 211) by half of the said period.

Title: Nozzle assembly for a scrubbing column
Inventor: RISSE THEO
IPC: B01D53/77
Filed: 1998-08-20
Abstract: A nozzle arrangement for a flue gas scrubbing column for use in desulfurizations, in which the scrubbing column has a sump, a baffle-free zone above the sump and a nozzle arrangement above the absorption zone.  The nozzle arrangement includes a branch pipe system for supply of a scrubbing liquid, and nozzles connected each by an intermediate pipe section to the branch pipe system.  The position and length of the intermediate sections is selected by:        (a) flow density profiles are formed in predetermined cross sectional planes of the scrubbing column by the spray cones of the nozzles;        (b) in each of these cross sectional planes, the flow density profiles of different spray cones are superimposed on one another;        (c) the flow density profiles of different cross sectional planes are superimposed upon projection thereof onto one of said planes to form a flow density complete profile in said one plane over the entire cross section of the scrubbing column;        (d) the flow density complete profile is compared with a predetermined value; and (e) upon deviation of the flow density complete profile from said predetermined value, the position of at least one of said nozzles is adjusted by varying at least one of the position and length of the associated intermediate pipe section; and (f) repeating steps (a) through (e) until the flow density complete profile for the cross section of the scrubbing column has an approximately constant value up to a wall region of said cross section.  The system of the invention optimizes the scrubbing of the gas and largely eliminates regions wherein the gas stream can pass through the scrubber without having been subjected to the scrubbing liquid in an effective scrubbing step. The result is improved absorption efficiency.

Patent CA-2247660-A1 (CA)
Inventor: JINGU NAOKI
IPC: F04B49/02
Filed: 1998-09-16
Abstract: A compressor protection apparatus and a method for controlling a compressor protection apparatus that prevents unnecessarily frequent on/off cycling of the electromagnetic clutch and, at the same time, prevents catastrophic damage of the compressor due to leakage of the refrigerant, are disclosed. In this control method, if a state of high engine rotational frequency has lasted for a certain duration, the electromagnetic clutch will be switched off temporarily. The control method takes into account the duration of high or normal engine rotational frequency, and thus prevents unnecessarily frequent on/off cycling of the electromagnetic clutch. Also the control method checks the compressor temperature when the engine rotational frequency is in a normal range. If the temperature is greater than a critical value, the electric power supply to the electromagnetic clutch is irreversibly switched off to inhibit the continued operation of the compressor. Therefore, the control method is able to stop the compressor by detecting a condition in which a refrigerant leakage is likely and, thus, prevent catastrophic damage to the compressor.
