Patent FI-822052-L (FI)
Inventor: HOLMES DAVID DUNLAP
IPC: H04N5/21
Filed: 1982-06-09
Abstract: A television ghost signal cancellation system is provided which compensates for the phase of the ghost carrier signal. A video signal containing a ghost signal component is applied to a variable delay line, which delays the video signal by an amount of time equal to the difference in time between the appearance of the direct video signal and its corresponding ghost signal components. The delayed video signal is modulated by a carrier signal and demodulated by a phase-shifted version of the carrier signal. The carrier signal is phase-shifted for the demodulator by an amount which compensates for the phase difference between the picture carriers of the direct and ghost signals. The demodulated signal is inverted and its amplitude adjusted to produce a pseudo-ghost signal which is substantially equal in amplitude but opposite in polarity to the ghost signal components. The pseudo-ghost signal is summed with the original video signal to cancel the ghost signal components, thereby producing a deghosted video signal.

Title: Valve for fire extinguishing installation
IPC: F16K17/38
Filed: 1976-06-08
Abstract: 1532002 Sprinkler control valve MATHER & PLATT Ltd 26 May 1976 [10 June 1975] 24859/75 Heading A5A [Also in Division F2] A control valve for fire sprinkler or deluge installations, comprises a pivotal valve disc supported by a spindle connected to an actuating lever 24, Fig. 3, which cooperates with a releasable mechanism resisting lever and thus valve disc movement. The mechanism is releasable by actuating means in the event of a predetermined condition responsive to a fire, e.g. a temperature or pressure. The actuating means in Fig. 3 comprises a weighted link 31 which when released by retraction of solenoid plunger 34, falls and pulls down pivoted catch lever 26 against action of spring 28. This releases the lever and thereby allows the valve disc to be opened by the controlled fluid pressure. The weighted link may be replaced by a weighted loop or noose which upon release from plunger 34 falls and pulls the catch lever down. In other embodiments, the catch lever is held in latching engagement with the lever 24 against the action of a spring by direct contact with a solenoid plunger (37), Fig. 4 (not shown), or with a diaphragm-actuated plunger (50), Fig. 6 (not shown), or by a fusible link device (41), Fig. 5 (not shown), comprising a pair of pivotally-connected curved links (42, 43) held in a closed loop relationship by a fusible bulb (44) which bursts when a certain temperature is reached or when a one-shot actuator (48) is operated. The lever 24 may be associated with two actuating means whereby operation of either one will permit the valve to open, Figs. 7 and 8 (not shown). Fig. 9 shows a valve having its lever 24 latched by a plunger 54 actuated by a diaphragm means 55 responsive, e.g., to downstream pressure, the lever 24 being manually re-settable to its latched position after release or automatically re-settable by a motorised actuator 56 in response to means detecting that the fire is extinguished or the temperature is normal. Preferably there is a time delay between such detection and the operation of the actuator 56. The latter may be replaced by a slowly rotating motor with limit switches, connected directly or through gears with the valve-disc spindle. A pair of valve discs may be located in series in a pipeline with their levers 24 interconnected, the discs being latched by a common single mechanism, Fig. 10 (not shown). Moreover, the pipeline space between the discs is drained when the discs are closed, so that upstream town water supply is isolated from downstream (and possibly contaminated) water. Fire fighting installations incorporating control valves of the invention are briefly described in the specification, Figs. 11 and 12 (not shown).

Abstract: Tyristor i en pulsgenerator som forsyner et elektrofilter beskyttes mot overoppvarming som følge av gjentagne overslag i filteret ved å la et overslag starte et observasjonsforløp,. ved hvilket forskjellen mellom antall inntrufne overslag inklusive overslaget som starter forløpet og antall ganger en forut valgt kjøletid er forløpet observeres. Når denne forskjellen blir 0 stanses observasjonen. Hvis forskjellen overstiger et fastlagt antall treffes foranstaltninger, som nedsetter overslagssannsynligheten, idet det ved stigende antall overslag treffes mer radikale foranstaltninger.Observasjonen foretaes ved å øke styrespenningen med et vist spenningsforløp hver gang et overslag forekommer og ved å la styrespenningen avta lineært med en hastighet bestemt av den nødvendige kjøletide. Når styrespenningen blir 0 stanser observasjonen inntil et overslag igjen bevirker en økning av styrespenningen.Forskjellige styrespenningsnivåer utløser forskjellige inngrep i filterets driftsparametre til reduksjon av overslagssannsynligheten.

Abstract: Method for charging Ni-Cd batteries with a repetitive and alternating sequence of direct current charging and discharging periods. Steep current pulses are superimposed on the respective direct currents which have a sense equal to that of the direct current and intensity exceeding respective predetermined levels. Owing to the effects of such alternating and repetitive current pulses the surface distribution of the electrodes will change after some time and the electrode surface gradually become homogeneous. The periodically repetitive steep current pulses can be used during the whole charging process and they have beneficial effects for the charging of new batteries as well. The current changes at the beginning of the respective periods should be at least seven times as high as one tenth of the ampere-hour capacity of the battery.
