Patent EP-0299233-A1 (EP)
Inventor: PINSON PIERRE
IPC: H03K17/80
Filed: 1988-06-21
Abstract: Two basic circuits include a common DC source (S4) and, respectively, two storage capacitors (C13, C15), and two trigger thyristors (T6, T7). They furnish two pulses, the duration of which is lowered in two compression stages in series. Each stage includes a storage capacitor (C14), and a saturable inductor (L13). A transformer (TR4) boosts the voltage a first time. The second compression stage is common to both basic circuits and includes two storage capacitors in series (C17, C18) which are independently charged from the two basic circuits, this making it possible to add up the voltages in the output load (Z4) without creating any disturbing coupling between these two circuits. <IMAGE>

Abstract: Algae growth in an open water system such as a water cooling tower is controlled by reducing the amount of light available for the algae to photosyn­thesize. The light available for photosynthesis is reduced by incorporating a dye into the water in the water cooling system. Thus the dye absorbs the light necessary for photosynthesis and in turn prevents algae growth. Preferably fluorescein at a concen­tration of 0.2 to 800 parts per million is incorpo­rated into the water in the water cooling system. Other dyes can be selected depending on the particular algae.

Patent EP-0318155-A1 (EP)
Inventor: AZEVEDO MICHAEL JOSEPH
IPC: H03L7/081
Filed: 1988-10-26
Abstract: An apparatus and method for digital correction of oscillator drift provides for phase alignment between two clock signals (10, 12) running at nearly the same frequency. Phase alignment is provided by fashioning a delay for one of the clock signals through selection of various lengths (40) of a variable delay path (20) formed from a series of logic circuits. Respective reference signals are derived from the two clocks to be phase-aligned, and the phases of the references are compared in a digital phase comparator (14). The product of phase comparison controls a digital delay selector (18) to generate a sequence of delay signals corresponding to a sequence of detected phase differences. The delay signal sequence controls the variable digital delay. The variable digital delay outputs a corrected clock signal whose phase is aligned with the phase of the other clock signal. The corrected clock signal is used to produce one reference signal, the other reference signal being derived directly from the other clock signal. A second digital phase comparator (22) compares the phase of the corrected clock signal with a predetermined reference phase of the clock signal from which it is derived. When the phases of the clocks are aligned, the second comparator produces a reset signal which resets the digital selection circuit to a predetermined point in the delay signal sequence, thereby operating the variable digital delay to correct the clock signal to a phase corresponding to the predetermined reference phase. The use of digital circuitry to correct for drift between the two clock signals permits the invention to be fully embodied in integrated digital circuits. The elimination of requirement for any analog circuitry to correct for oscillator drift permits phase alignment at various points along the line of clock distribution in an integrated digital system.   
     By use of the invention, phase alignment can be performed on-chip between discreet functions on a single integrated circuit, between separate integrated circuits, and between independently-operating digital systems.
