Title: Floating gas-liq. exchange appts. - for oxygenation of large vols. of water such as lakes
IPC: C02F3/20
Filed: 1973-10-31
Abstract: Gas-liq. exchanges, partic. water-oxygen exchanges where it is necessary to treat large quantities of water in lakes, rivers or purificn. stations for large towns, are effected in systems which require only a small amt. of energy and which occupy little space. The appts. for oxygenating the water in a lake draws the water in through an annular orifice and the water rises in the concentric tubes under the action of a motor driven pump. The water descends in the central tube, drawing in air bubbles, by the reduced pressure, through a tube, fitted with a valve; the water reaches the base of the central tube and rises again in an annular tube. It is rejected into the lake after effecting oxygenation by its bubbles. The latter continue to rise up the annular tube and pass an adjustable nozzle where they commence to treat the incoming water. The partly deprived bubbles pass into a separator and leave for the atmos. by a tube. The water meets fresh air entering at the top of the central tube and mixes with it while descending the tube. The oxygen-water exchange is made under the most favourable conditions towards the base of the tubes where the press. is highest; the efficiency attained enables the quantity of gas introduced to be reduced to the minimum. The appts. is maintained in the floating position by an immersed, annular float.

Title: Rotation measuring ring laser rate gyroscope - has two electro-optics crystals and two sensors for two laser beams
IPC: G01C19/68
Filed: 1973-12-27
Abstract: The ring laser rate gyroscope is used to measure angular velocity and rotation. It has a laser source (1) producing two laser beams, of the same frequency, which go through two identical electro-optic crystals (2, 3) such as piezoelectric quartz or strontium niobate. The crystals from a voltage generated by a pulse generator (30) and transformed by a circuit (31). When the gyroscope is subjected to an angular velocity, frequency differences due to an effect similar to the Doppler effect are detected by two sensors (4, 5). The signals from the sensors (4, 5) are then modified to obtain the value and the sense of the measured angular velocity.

Patent FR-2264928-A1 (FR)
Title: Flushing mechanism for water closet - has outlet valve float locked on outlet by manually released air lock
IPC: E03D1/30
Filed: 1974-03-21
Abstract: An elastic float obturator (25) reciprocates vertically in a closed top cylinder (83) between respective upper and lower open and closed stations. The cylinder guide (83) locates in the tank with its open end (81) axially over and adjacent to the outlet (21) and embodies a lever (69) actuated air valve (63) in its closed top (55). When the tank is empty the spherical or conical float settles on and seals the outlet. The tank around the cylinder now fills with water effecting an air lock in the cylinder, this air pressure augmenting the obturation seal. Opening of the air valve (63) remove the air lock and allows water into the cylinder, thus unseating the float so flushing water flows through the outlet.

TW of the laundry is continuously compared with the temp. TT of the drying air and the stopping signal is selected from the time period corresponding to the joining of the time period DELTA t Tc, where the temp. TW is const. by the time period DELTA t Ta and at which time period the thermal differences of the temp. (TT TW) do not exceed a critical value (G DELTA) or the time differential d TW/dt) of the temp (TW) exceeds a critical value (Gd). Cycle of laundry drying is stopped when the residual moisture in the laundry is at its optimal value preventing creasing and making subsequent ironing more difficult.

Title: Fuel control system for gas turbine propulsion - fuel flow is regulated by working conditions with compensation for pressure drop
IPC: F02C9/32
Filed: 1974-10-29
Abstract: A centrifugal fuel pump delivers fuel to a variable metering unit consisting of two sliding covers inside a fixed cover. The first cover is moved in respect to the fixed cover by a centrifugal governor driven by the turbine shaft. A step motor controlled by a digital unit moves the sliding sleeve by a series of cams and rollers. The digital unit responds to the turbine shaft r.p.m. temp., combustion chamber temp. the position of the lever for reverse and forwards thrust and aircraft height. The inner sliding cover is moved by a lever connected to a unit containing two bellows in tandem and actuated by compressed pressure to increase or limit the fuel flow. A shaft extends axially through the cover to end in a piston unit which slides inside a stepped bore with apertures connected to the pressure side of the fuel pump. The piston unit is controlled by a second set of centrifugal weights dependent on turbine shaft r.p.m. with springs to tension the piston upwards to ensure an adequate flow on ignition. A channel leads from the piston unit to the pilot burners.

Title: Transparent tracing paper for indian ink drawing - treated with nonvolatile organic acid to improve receptivity for slightly alkaline ink
IPC: B42D15/00
Filed: 1974-11-29
Abstract: Transparent tracing paper for Indian ink drawings is improved by treating its surface in such a manner that its pH is shifted into the acid range.
