Title: Motor vehicle auxiliary battery cct. - prevents start voltage drops for other loads by using diode between both batteries
IPC: H02J9/06
Filed: 1974-06-27
Abstract: The auxiliary battery circuit for motor vehicles has the main battery connected by its positive terminal to the alternator output, and over a diode to the auxiliary battery positive terminal. The loads are divided into two groups. The sensitive loads are supplied during starting from the auxiliary battery, and in normal conditions from the main battery, whilst the remaining loads such as the starter motor are supplied exclusively from the main battery. The diode is so poled that current flows to the auxiliary battery, but from the auxiliary, battery to the starter motor. The diode therefore isolates the sensitive loads from the drops in voltage experienced by the main battery when the starter motor is switched on.

Patent FR-2297075-A1 (FR)
Title: Mixing of fluids with different specific weights - in nozzle with internal venturi for accelerating lighter fluid into which is sprayed additive fluid to increase its specific weight
IPC: B01F3/04
Filed: 1975-01-09
Abstract: A mixing nozzle has cylindrical and converging sections through which a central tube carrying the main fluid to an injector nozzles passes. Inside the cylindrical section is positioned a venturi for accelerating the lighter fluid. Adjustable blades at the inlet to the cylindrical part create a turbulence and divert some or all of the lighter fluid into the venturi. Spray cones in the form of ultra-sonic probes or mechanical micro-sprayers are positioned in the venturi for the introduction of an additional fluid. At the end of the converging part of the nozzle is another set of adjustable blades which direct the light fluid that flows around the venturi towards the main fluid injector and ensure the evacuation of gases through a spray cone at the end of the converging part. One or more electrodes are placed at the main fluid injector outlet to ignite the mixt. The lighter fluid e.g. a combustive that is accelerated through the venturi is increased in specific wt. to bring it closer to that of the main heavier fluid e.g. a fuel by the addition of a predetermined proportion of a fluid, which may be the main fluid itself, water in liq. or vapour form, a hydrocarbon liq. or gas or a fine powder. That portion of the lighter fluid which does not pass through the venturi reaches the convergent part of the nozzle at a slower speed than the accelerated portion creating a suction which removes gases given off at the time of combustion. In processes, e.g. dyeing, where the lighter fluid is air, the air can be preheated. Used in combustion and motors where heavier fluid is a fuel or carburant and the lighter fluid is a combustive, and dyeing and bleaching of e.g. textiles, papers, where the main fluid is a colouring or bleaching soln. It gives a more uniform mixt. constantly.

Title: Ethephone contg. fungicide - decreases amt. fungicide required and shows marked effect against both storage and soil diseases
IPC: A01N57/20
Filed: 1976-03-19
Abstract: An agricultural and horticultural fungicidal compsn. comrpises 2-chloroethylphosphonic acid ("ethephone") is added to agricultural and horticultural fungicide as a synergist. Though ethephone itself is known as a plant growth regulator, it has no fungicidal action and has very low toxicity. By adding a small amt. of ethephone to a prior fungicide, even half the amt. of the effective ingredient exhibits a sufficient fungicidal action. This agent is sufficiently effective with half the spraying time of the prior chemicals. This compsn. is markedly effective against both storage diseases and soil diseases. Since the amt. of fungicide used can be greatly reduced, this compsn. is useful in view of the economical effect and natural environment. In an example, methyl-1-(butylcarbamoul)-2-benzimidazole-carbamate 50 pts., 35 pts. of clay, 10 pts. of carplex (made by Shionogi), 2 pts. of Sorpol 5039, and 3 pts. of lignin were mixed homogeneously and ground. This was diluted with water to give a fixed concn.
