Title: Polypropylene moulding - for recessed lifting holds in cast concrete structures
IPC: E04G21/14
Filed: 1970-12-30
Abstract: Anchorage well for accepting a 'g' sling hook for lifting concrete beams or panels where the well comprises an open-topped trough traversed by a beam set in the concrete on either side and to which a lifting hook can be secured.

Title: Sectional boiler with annular sections - alternate ports blanked off to ensure circuitous water flow
IPC: F24H9/14
Filed: 1973-06-19
Abstract: A section boiler is made up of annular units (1, 2) through which the water circulates, each face incorporating two holes (A, B) at the top and one (C) at the bottom, and these holes can be interconnected by barrel shaped nipples when one section (1) abuts the next section (2). A barrier plate (4) is incorporated between the two upper holes. To ensure that the greater part of the flow follows a meander path as it travels from section to section, alternate nipples in the top two holes are blanked off, and the bottom nipple is also blanked off so that the liquid must make a complete circuit around each section. All the blanked off faces contain however a small hole to permit evacuation of air and subsequently drainage.

Patent FR-2249272-A1 (FR)
Title: Oil flow regulating valve for automatic vehicle transmission - ball is urged against conical valve seat by conically wound coil spring
IPC: F16K17/04
Filed: 1974-10-22
Abstract: Non-return valve comprises a ball seated on a conical valve seat formed between two cylindrical oil ways of different diameters. The larger oilway is of greater diameter than the ball so that as the ball moves away from the valve seat it cooperates with the valve seat to define a steadily increasing flow area. The ball is urged against the valve seat by a coil spring which has conical windings, reducing in diameter at its end adjacent the ball. Valve reduces the possibility of turbulent flow through the valve seat by keeping the seat cone angle between 30 deg. and 90 deg. and the spring reduces transverse oscillations of the balls.
Patent FR-2249477-A1 (FR)
Title: Electronic 'kick-start' circuit for A.C. loads - is used to enable loads to be driven with low-power setting
IPC: H02M5/257
Filed: 1974-10-25
Abstract: When thyristor and triac speed controllers for motors are switched on with a low setting the current drawn may be below the hold current of the semiconductor. To avoid adjustment to start the load a by-pass circuit is used. The thyristor/triac may have an unijunction transistor and a capacitor, or a diac and capacitor firing components with a control potentiometer. The by-pass is a capacitor in series with a diode, in parallel with another capacitor and diode in the opposite direction connected across the thyristor/triac. Both of the capacitors have parallel discharge resistors. When the mains is connected a heavy full-wave current is drawn through the load until the capacitors are charged.
Patent FR-2272888-A1 (FR)
Title: Transfer system for crude petroleum - between a tanker and a reservoir or distribution terminal on the sea bed
IPC: B65D88/78
Filed: 1975-02-11
Abstract: Petroleum is transferred to or from an oil tanker by positioning the tanker directly above a petroleum storage reservoir or a distribution terminal installed on the sea bed, maintaining it in this position, unwinding a flexible pipe for connecting the tanker to the reservoir or terminal, guiding a connector element on the free end of the pipe towards a further connector using an automatic guiding system, joining the two connectors, thus automatically permitting petroleum to flow through the connexion, delivering it in the flexible pipe through a suitable orifice in the bottom of and halway along the tanker, and allowing the petroleum to pass from the reservoir to the tanker or from the tanker to the terminal by pumping. The underwater storage reservoir is well below the level affected by storms etc. and cannot form a navigational hazard. Petroleum can be delivered to storage at all times whatever the surface conditions. The petroleum can be transferred to the tanker without the use of pumps, by utilising hydrostatic pressure. The system is particularly useful in deep water and for oil wells at long distances from a land base.
Patent FR-2307550-A1 (FR)
Title: Distribution centre supplying dialysis liq. to several terminals - with automatic control of concn. and sepn. of gases
IPC: A61M1/16
Filed: 1975-04-14
Abstract: A process for prepg. and distributing dialysis liq. to several terminals, feeding artificial kidneys, charges pre-determined amts. of concentrate and softened water to two containers, and transfers the matl. to a storage vessel through a homogenising vessel. Photoelectric cells operate valves to control the amts. of concentrate and softened water. REsistivity meters detect concn. changes and operate valves directing the flow to the storage vessel or to drain according to whether the concn. is correct or not. A nitrogen supply and an acceleration pump creating a depression i the storage vessel ensure that dissolved oxygen diffuses out of the dialysis liq. and a degassing vessel ensures liberation of nitrogen. The invention provides more reliable and safer means of ensuring correct concn. than existing appts. Breaks in distribution are avoided. Correct flow according to the number of terminals in use is assured. The dialysis liq. is free from dissolved gases which could affect the efficiency of the dialyser and which could get into the blood stream.
Patent FR-2270784-A1 (FR)
Title: Sprinkler-stand mounted on wheeled chassis - stand-pipe with horizontal connecting pipe angled from it
IPC: A01G25/09
Filed: 1975-05-16
Abstract: The stand-pipe is connected to a metal container from the lowest point of which runs a horizontal pipe after an initial bend. The pipe constitutes the inflow pipe and is connected, after another bend, by means of a rapid coupling to the water-supply pipe. Both ends of the large container have bearing blocks for wheels on which the stand runs, with the horizontal pipe acting as a draw-bar. If the horizontal pipe is connected to the pipe, the container fills up with water, before the sprinkler starts working. After sprinkling has finished and the rapid coupling releases, the water runs out of the container through the horizontal pipe.
