Title: Cooling tower - with parallel air flow through direct and indirect water contactors
IPC: F28C1/14
Filed: 1972-03-30
Abstract: Water is cooled by flow, first through finned tubes, and then in a direct contact cooler; the air streams from the indirect and direct coolers are combined before venting, to reduce the saturation of the vapour, and avoid pluming, even under adverse conditions. May be applied to both forced and natural draught cooling towers, with forced draught pref. the finned tubes are vertical, and water exits from their open bottom ends which remain immersed, thus exerting a syphon effect to aid pumping, with natural draught, water makes a double pass through finned tubes. Air flow through direct and indirect coolers may be separately controlled to vary air mixing ratio according to ambient humidity and temp the indirect cooling tubes, surround the base of the cooling tower, above the air inlet to the direct cooling provision inside the tower.

Patent FR-2175000-A1 (FR)
Title: Electrolytic water purificn process - for industrial and domestic waste water
IPC: C02F1/467
Filed: 1973-03-05
Abstract: Waste water is purified in an accelerated manner by dipping one or more anodes in the water; these cause evolution of oxygen which is in the nascent state and is partic. active. It can start and accelerate the chemical degradation reactions of any foreign materials. Prods., which normally are non-degradable by micro-organisms, can be oxidised; there is a marked acceleration of these degrading reactions thus increasing the capacity of the treatment plants. As the efficiency of the treatment increases with the surface area of the anode, the latter is pref. made from a metallic gauze. Hydrogen is disengaged at the cathode, which is therefore placed so that it will have little or no contact with the liq. being treated, e.g. by using a porous wall. The hydrogen can be recovered.

Title: Stationary supporting structure - has central steel pipe passing through stack of hollow sections filled with concrete
IPC: E02B17/02
Filed: 1974-11-12
Abstract: The structure is particularly for platforms above sea level, comprising a column or set of columns secured together, and each of prefabricated sections placed one on top of the other. A central vertical steel pipe extends through openings in the sections, which bear against each other by means of mating convex and concave surfaces. The lower end of the pipe is secured to a prefabricated concrete foundation piece, on which concrete column sections are stacked, the openings in them being of larger diameter than the outside diameter of the pipe. The intervening space is filled with concrete, as is the space inside the pipe simultaneously to form a rigid concrete unit. Thus the pipe is embedded in the concrete and acts as a reinforcement against bending loads.

Title: Wall panel jointing clamp - has tapered cast steel key with ratchet teeth cutting locking teeth in loop and peg
IPC: E04B1/26
Filed: 1975-05-29
Abstract: The clamp is used for the assembly of wall panels and shuttering. Shafts (1) joined onto one panel are inserted in U-shaped clips (2) carried by the other panel. A conical tapered cast steel key (3) is then hammered through holes provided in the flanges of the clip. The key is cast with longitudinal ribs forming ratchet teeth in cross-section and it has a square or hexagonal tang (5) at the thick end. When hammered in, the ratchet teeth cut complementary shaped teeth in the clip and the surface of the shaft, and the assembly may be secured by turning the key by means of the tang. The key may be replaced by auto-locking clips actuated by a cam on the shift. This variant can be used in an extended form for panel alignment fittings.

Title: Safety control for railway pneumatic brakes - with venting line to all parts ofsystem to isolate train
IPC: B60T15/02
Filed: 1975-09-30
Abstract: The train pneumatic brakes are fitted with a shut-off control by means of which the whole train can be isolated, without any brakes jamming on. The shut-off control closes the supply line to the brakes and opens a special venting valve by means of which the reservoirs and the high pressure brakes are connected to the atmosphere via non-return valves. The system is arranged so that the shut off valve operates effectively no matter in which setting the brakes were last left. It is to the purpose to have the recoil valve related to the maximum pressure limiter (30).

Title: Liq. pollution measuring appts. - operates solvent rinsing and calibrating cycles before counting particles in given vol. of liq.
IPC: G01N15/14
Filed: 1975-12-02
Abstract: The device operates in five phases. Solvent from a reservoir (11) is decanted into a chamber (9) from where it is forced by pressurised air from a source (10), to counter flow through read head (3) to rinse it clear of particles from a previous reading. The solvent is filtered (26) and collected in receptional (22) to be used again. Preference liquid is placed on magnetic stirring input (39) and applied, again under force of pressurised air delivered along conduit (32) to the read head (3) in which is thereby calibrated. Now the head (3) is re-rinsed and the liquid to be measured for pollution is introduced through the first circuit after which the cycle may be repeated.
