Abstract: The present invention relates to a method of manufacturing a flexible electric cable with a tinned stranded conductor on which insulation is applied at a high temperature. Previous diffusion of tin in the copper of the conductor strands makes it possible to prevent the strands from blocking together while the insulation is being formed at a temperature higher than the melting point of tin, while still leaving a final layer of pure tin at the surface of these conductor strands. Application to manufacture of aircraft cables.

Abstract: The invention relates to a device for determining the granulometric composition of a mixture of particles by diffraction of light. The light flux received on the diffraction pattern is measured in a number of diffraction areas (AI,AJ) each of which is in the shape of an angular sector of circular rings which are concentric with the pattern, these integration areas forming two successions in each of which the inner and outer radii form geometrical progressions with common ratio of two, the ratio between the outer radius and the inner radius of an integration area being chosen in the interval between two and the square root of two, the radii within one succession (AJ) being equal to those within the other (AI) multiplied by the square root of two. Application to studying powder mixtures.

Abstract: Two sets of cymbals are mounted on two pairs of horizontally extending arms respectively of a support bracket which in turn is adapted to be mounted adjacent the upper end of a conventional hi-hat support stand of the type having a foot pedal operated rod vertically reciprocable within a hollow tube. The lower arms which support the bottom cymbal of each set of cymbals are detachably clamped to the hollow tube and the upper arms which carry the upper cymbal of each set of cymbals are secured to the upper end of the vertically reciprocable rod and guided relative to the lower arms by means of a guide blade secured to the upper arms and complementary guides secured to the lower arms. A spring is connected between the guide blade and the complementary guides for normally biasing the upper arms away from the lower arms.

Abstract: Waste water and sludge is supplied through an inlet 12 to a flotation basin 10 where a skimmer 14 collects floating solids and sweeps sunken solids into a bottom discharge trough. Water from the basin is drawn off through a line 16 and fed by pumps 18, 20 into an air pressurized container 26 through an ejector 24 which draws in and dissolves the compressed air in the water by aspiration or eduction. The air saturated water is then fed back into the basin through valves 42, 44 where the reduced pressure releases the air in the form of micro-bubbles, which reduce the surface tension of the waste water to release sludge particles and float them to the surface for skimming off.

Abstract: A power-generating installation comprises a plurality of modular power plants each comprised of an internal combustion engine connected to an electric machine. The electric machine is used to start the engine and thereafter operates as a generator supplying power to an electrical network common to all the modular plants. The installation has a control and protection system comprising a plurality of control modules each associated with a respective plant, and a central unit passing control signals to the modules to control starting and stopping of the individual power plants. Upon the detection of abnormal operation or failure of its associated power plant, each control module transmits an alarm signal back to the central unit which thereupon stops, or prevents the starting, of the corresponding power plant. Parameters monitored by each control module include generated current and inter-winding leakage current of the electric machine.

Abstract: A spraying device for cleaning apparatus, plant protecting apparatus or the like including a hand tool connected via a conduit to a pressure and heat generator for providing a liquid or vaporous agent under high pressure. A switch lever is held in the on position during operation. The lever controls a switch, the activation of which causes a transmitter for electric or electromagnetic waves arranged in the hand tool to send a switch-on command to a receiver located near the pressure and heat generator. The receiver operates a switch for controlling the pressure and heat generator, whereby upon release of the hand tool, such as unintentionally in the case of a dangerous condition, the switch-on command of the transmitter is interrupted and the pressure and heat generator switched off.
