Title: Plastic or wax cartridge for distribution gun - formed in mould cooled by cooling gas to form hard skin around cartridge
IPC: C09J5/00
Filed: 1973-12-13
Abstract: A cartridge of e.g., plastic adhesive or wax for loading into a distribution gun is formed by pouring molten material into a mould and cooling the surface of the mould and the free surface of the material so that a hard skin is formed. Cooling is effected by direct heat exchange with a cooling gas which flows pref. through a jacket around the mould and which is pref. directed as a jet from e.g., a nozzle onto the free surface of the material. Subsequently, the remaining material within the hard skin is cooled slowly to solidify. The material may be rendered liquid again by heating. The process is quicker and cheaper than conventional processes. The cartridge contains no impurities, e.g., water droplets.

Title: Controllable wing section for light aircraft - has flexible surfaces responding to variable internal pressure
IPC: B64C31/028
Filed: 1973-12-20
Abstract: The wings are constructed with hollow cylindrical leading edge spars (35) and hollow triangular trailing edge spars (36) connected by flexible membranes forming the upper and lower wing surfaces (37, 38). Various methods are described by which the air pressure inside the wing may be controlled and thus change the wing section. One method is to construct shielded holes (42) in a region of low pressure of the upper surface and to supply air at high pressure via a valve (45) from a total pressure tube (44). Adjusting the valve controls the inflation of the membranes and thus the lift generated by the surface. Differential control of the half wings given roll control. The wing is intended for use as a paresol wing with a light cockpit/gondola.

Title: Collector for window cleaning liquid - has reservoir with upper suction device andconnection tube mounting boss
IPC: A47L1/02
Filed: 1974-03-29
Abstract: The device comprises a vessel or reservoir (1), carried on the operator's back haversack fashion, incorporating an external flexible collection tube (12) with flared combination suction and scraper head (13), and a suction device on its top.

Title: Telescopic shock absorber with adjustable characteristics - edges moulded to form complementary cross sections
Inventor: TOURNOT ROGER
IPC: F16F9/44
Filed: 1974-11-14
Abstract: A telescopic hydraulic shock absorber is used in which regulation of the resisting effort can be made from the outside. There are two adjustments, which can be separate or combined.

Title: Model wing surface pressure detector - employs orifices in surface feeding tubular transmission channels within wing
Inventor: JOURDAN PIERRE ARMAND JULIEN
IPC: G01M9/08
Filed: 1975-03-12
Abstract: Pressure of a fluid on the surface of a wing model is sensed by having orifices on the surfaces which lead to tubes in a channel within the model. These tubes are connected to measuring instruments and the method avoids presence of discontinuities on the surface. Pressure on the surface of a wing model (1) is detected at points (a1-6) located on a line (B) traced on the wing surface. At each point an orifice leads (Fi) into a tubular cavity (3) in which the pressure is transmitted (6) along channels (7) displaced around the axis (5). The orifices lead into annular throats (9) with an elasticated sealed joint (10) for pressure transmission along a particular channel (F1, F2, F3). The channel tube end (11) permits connexion to capillary tubes for pressure measurement.
