Patent FR-2236022-A1 (FR)
Title: Automatic cleaning, washing or degreasing machine - for all mechanical and electrical parts, using jets of liq. solvent
IPC: C23G3/00
Filed: 1973-07-06
Abstract: A machine uses a closed circuit for the solvent and two, synchronised actions, (a) cold spraying, under press., of the cleaning solvent from jets located in all planes, and (b) the slow rotation, on its centre, of the piece of assembly being cleaned; the entire surface of the piece is thus exposed to the solvent, the impact of the spray being equivalent to mechanical brushing. The piece being cleaned may be placed at the centre of a perforated plate which can pivot on its axis, the jets being staggered w.r.t. the axes of the piece, which thus rotates with the supporting plate due to the spray press. No heat is required and the pieces are not rotated mechanically but only by the jets.

Title: I.C. engine anti-pollution device - shuts off carburettor from engine when accelerator pedal is released
IPC: F02M23/06
Filed: 1973-07-27
Abstract: The duct (1) is connected to the atmosphere by the inlet (3) and is connected to the intake manifold by the duct (2). The valve (4) is operated by the lever (5) and rod (6) connected to an electro-magnet (7) in the housing. The electro-magnet is connected to the ignition coil or to the contact breaker and is energised through a switch operated by the accelerator pedal. When the vehicle speed is reduced by releasing the accelerator pedal the valve (4) is opened and the normal throttle valve fully closed so that only pure air passes through the engine, reducing pollution under engine braking conditions.
Patent FR-2249001-A1 (FR)
Title: Item pneumatic tube conveyor - has emitters detecting slug passage controlling overflow valves at each section
IPC: B65G51/22
Filed: 1973-10-26
Abstract: Overflow valves discharge the compressed air temporarily at the loading and unloading stations to allow the transport slugs to be halted there, and work under the control of emitters after each station detecting passage of the slugs, which cause them to open and close accordingly. The overflow valves are so spaced along the tube that they divide it into sections in which during movement the slug or train of slugs are. The number of such sections is at least one more than the number of slugs or slug trains in the system at one time, and individual emitters are mounted downstream of each valve. These transmit signals to open the valve in the next section and close that in the previous one.

Title: Method of forming rolled edges on hinges - involves preforming edge before it turning with a curved die
IPC: B21D53/40
Filed: 1973-12-19
Abstract: The first operation consists of forming an angle of approximately 80 deg. on one short side (2) of the blank (1) and drawing down one edge (3). In the second operation, this side is bent down to form a partial curve (10). This is used as a preform in the final operation which is done in a press using a stationary die (33) and a tool (17) moving linearly in a horizontal direction. The preformed blank is clamped securely (32) during the forming operation; the curved section being forced round until the angled side (2, 3) meets the inside (6) of the blank to form a cylinder with a central bore.

Title: Automatic cold starter for engine carburettor - has electrical resistance heaters with a positive coefficient of thermal expansion
Inventor: PAULMIER CLAUDE
IPC: F02M1/12
Filed: 1974-03-19
Abstract: The automatic device for the carburettor ensures that the engine can start in the cold state and it continues to supply an appropriate mixture until the engine has reached its steady running temperature. A bimetallic spiral is connected to the starting valve of the carburettor and this spiral is exposed to the heat of two series connected resistors with a positive coefficient of expansion. These resistors are connected to a plate whose other side radiates heat on the bimetallic actuator. The system has a switch with a negative coefficient of thermal expansion and this switch actuated by the engine temperature is used for short circuiting one of the resistors at a lower temperature. The resistors and the bimetallic actuator are held in a housing and the bimetallic spiral actuates the throttle by a crank.

Title: Reduction of fluid flow friction loss in pipelines - by injection of polymers in crumb form, pref as a slurry with a non-solvent
IPC: C10L1/18
Filed: 1975-03-28
Abstract: Polymeric materials are injected in small quantities into flowing hydrocarbons in pipelines to serve as friction reducing agents. The polymer (pref. polyisoprene) is prepd. and injected into the pipeline as polymer crumb, pref. slurried in a non-solvent (pref. water) and pref. after dusting with a combination of 2,6-di-tert-butyl-p-cresol and 2,2'-methylenebis-(4-methyl-6-tert-butylphenol) to reduce oxidative degradation of the polymer. The particle size of the polymer crumb is about 3/8 inch dia. and requires about 2-4 days to completely dissolve in flowing crude oil. Use of polymer in crumb form aids dissolution rate in flowing hydrocarbons, (c.f. shredded or ground forms of polymer). The system avoids pre-soln. of polymer and associated degradation by shearing, and provides continuous source of dissolved polymer in flowing hydrocarbon. Use of non-solvent and/or dusting with anti-oxidant prevents significant oxidative degradation of polymer. Friction loss redn. of up to about 80% can be achieved.

Title: Sintered hard metal tools based on tungsten carbide - where high impact resistance is combined with high wear resistance
Inventor: IVENSEN V A
IPC: C22C1/05
Filed: 1976-01-26
Abstract: Process for mfg. sintered hard metals based on tungsten carbide, by redn. of tungstic oxide in hydrogen to obtain metallic tungsten, which is then carburized at 1800-2400 degrees C to form tungsten carbide which is mixed and milled with a metal binder, then pressed and sintered. The novelty is that the WO3 is first reduced to 750-1300 degrees C. to obtain WO2 which is then reduced at 1000-1600 degrees C to obtain metallic tungsten. Used for mfg. upsetting-, cutting- and boring tools. The tungsten carbide produced by this process possesses high wear resistance combined with high resistance to impact loads, a combination hitherto unobtainable. The plastic deformation of fine and medium grained material (0.5-1.5 mu m and 2-3.5 mu m) is increased two to four times. The improved impact resistance is due to the formation of a complete crystal lattice structure with uniform, small grain size and without irregular inter growth.
