Title: Alcohol fuels contg. water or hydrogen peroxide - ans a sulphonated fatty material
IPC: C10L1/10
Filed: 1974-02-22
Abstract: Modified alcohol fuels contain (a) sulphonated fatty materials (mineral, vegetable or animal) and (b) H2O or H2O2. The fuels can contain =30% H2O or H2O2, =30% sulphonate, =15% hydrocarbon, opt. =10% ether, and opt. also a protective lubricant. They can be prepd. by mixing the alcohol and H2O (or H2O2), adding the ether and then the hydrocarbon, and then adding the sulphonate while agitating vigorously. The incorporation of H2O or H2O2 in alcohol-based motor fuels allows savings to be made in fuel consumption while increasing combustion efficiency, reducing CO emission, and giving good cold-start performance and smooth running, without requiring any modifications to fuel-supply system or engine design. The presence of the sulphonate also allows hydrocarbons to be added to the fuels.

Patent FR-2231111-A1 (FR)
Title: Bipolar transistor for large scale integration - using same window with added masks for triple diffusion
IPC: H01L27/06
Filed: 1974-05-24
Abstract: To produce a bipolar transistor for integrated circuits, a silicon dioxide layer on a semiconductor substrate is etched to form an elongated window, using the layer as a permanent mask. This represents the outer boundaries of a diffusion transistor. After a first doping operation through the window, the window is successfully masked in length, leaving the same width, to produce a second and third diffusion of impurity atoms. This system avoids the difficulties with the positional tolerance of subsequent photolithographic processes. It produces triple diffused transistors of high packing density and low dissipated power.

Title: Fail safe automatic headlamp dipping control - with axle signals acting as additional force on headlamp servo to dip lights if servo fails
IPC: B60Q1/105
Filed: 1976-05-07
Abstract: The front and rear axles of the vehicle are fitted with pneumatic/hydraulic monitors to sense the axle loading, and these monitors are coupled to slave servos in the headlamp tilting control to adjust the headlamp inclination to compensate for axle loading. To provide a failsafe system, which ensures that the headlamps do not swing up to dazzle oncoming traffic, if one or both servos fail, the salve cylinder on each headlamp has two pistons linked by a spring and with the first piston linked to the tilt control by a spring linkage. The output of the two axle servos are introduced on opposite sides of the second piston, so that their total effective force, being the difference in the outputs, pushes against the sprung linkage to lift the headlamps.
