Title: Diesel engine speed limiter - has fuel pressure regulating valve on injection system held open when speed exceeds set level
IPC: F02M63/02
Filed: 1978-05-05
Abstract: Excess fuel from the injectors is returned through a common pipe (15) in which there is a spring loaded pressure regulating valve (17). The valve stem is extended to carry an armature (22) which can be pulled back by a solenoid (23) is energised from the engine battery (25) through a tachometer (26). Alternatively the circuit can pass through a switch (28) mounted on the gearbox (29). With either arrangement the pressure regulating valve is held open when the engine exceeds a preset speed. This reduces the fuel pressure and therefore the quantity injected.

Patent FR-2437033-A1 (FR)
Title: Perforated card reading system for record keeping - uses fibre=optic sensors to create binary signals using phototransistors
IPC: G06K7/10
Filed: 1978-09-20
Abstract: The need for sensitive and fragile scanning equipment is eliminated in a rapid card reading device. A matrix of 49 fibre optic terminations (12) is positioned adjacent to the punched card (7) in order to selectively collect light transmitted from an illuminated scattering plate (5) through the holes. Photo-transistors at the end of each fibre optic cable convert the presence or absence of light into TTL compatible binary data which may be stored in an electronic memory. Information coded in the pattern of perforations can thus be obtained almost immediately. The card housing (9) ensures that the card is automatically correctly positioned with little freedom of movement. Control perforations can be used as a trigger for the light source when a card is introduced.

Title: Removal of solid impurities from detergent lubricating oil additives - by addn. of polar solvent and phase sepn.
Inventor: SPITSYN V I
IPC: C10M177/00
Filed: 1978-10-10
Abstract: Mechanical impurities are removed from detergent additives for lubricating oils by phase sepn., after addn. of 0.025-10 wt.% polar liquid with dielectric constant >=17 to the additive soln. Solid particles of 0.5-5 mu m size resulting from synthesis of the additive, e.g. by neutralisation of sulphonic acid soln. in oil with Ca(OH)2. which are very difficult to separate, are reduced to below 500 mg/100 g. Prolonged centrifuging with sepn. factor 1000 and super-centrifuging: with sepn. factor 15000, are eliminated. The process causes coagulation of the particles, which increases their sedimentation rate around 1000 times.
