Title: Pivoted wing aircraft with pilot operated control - transfer wing load to undercarriage on take-off
IPC: B64C3/38
Filed: 1973-05-03
Abstract: The wing (5) is pivoted on a rod (14) which passes through guides in the fuselage (1) to be attached at its other end to the undercarriage (2).

Title: Continuously separating light from heavy liquid - eg oil from water using vacuum pump and relatively small vacuum vessel
IPC: E02B15/04
Filed: 1973-12-11
Abstract: An apparatus for sepg. liqs. from two phases of different spgr. e.g. for separating oil from water, comprises a vacuum pump and an articulated suction line connected a float with its inlet at a constant level below the liq. surface a continuously operating extraction lock is incorporated into the suction line. This extraction lock is pref. constituted of several, (e.g. three) lock chamgers which are each connected in turn in a sealed manner to the suection line so that the suction from the immersed suction line leads directly to the pump. With this arrangement, only the chamber of the lock which is operative is subject to vacuum therefore only the lock unit needs to be designed for vacuum, at the same time continuous operation is possible since the lock chambers discharge in succession into a tank at atm. press.

Patent FR-2289751-A1 (FR)
Title: Water injection system for IC engine - reduces fuel consumption and pollution
Filed: 1974-03-04
Abstract: The water injection system consists of a water tank with a pump which pumps the water through a controlling orifice through a pipe which runs through the exhaust pipe.

Title: Photometric titration system for blood serum - measuring titration agent to compensate light intensity change by indicator addition
IPC: G01N21/77
Filed: 1974-10-08
Abstract: In a photometric titration system the indicator solvent is mixed with the specimen in a transparent dish. The intensity of a light beam passing through the dish is changed by adding an indicator. Adding a titration agent reverses this reaction and the amount of agent needed to return the intensity to the initial level is recorded; it is proportional to the desired concentration in the sample. Any gradual changes in the instrument or accessories affecting the light intensity are automatically compensated at each titration. This system produces highly accurate and reproducible results.
