Title: Systemic fungicides contg. copper chelates - with Zineb or Maneb and an iron ferrate complex
Inventor: SZAVA JENO
IPC: A01N47/12
Filed: 1974-12-24
Abstract: Systemic fungicides contain (a) 0.1-99 wt % of a combination of (i) Zn and/or Mn ethylenebis-dithiocarbamate, (ii) an alkali(ne earth) metal salt of a glycine-N-dimethylamino-2-hydroxy-5-sulphobenzyl copper chelate, and (iii) a ferrous or ferric salt of a ferrate complex, (b) opt. 0.1-1 wt % of a surfactant, and (c) 0.1-99.9 wt % of inert extenders and carriers. The fungicides are esp. useful for the control of Plasmopara viticola on grape vines. The Cu chelate cpd. is water-soluble but does not release phytotoxic Cu ions in soln. when the Mg salt of the Cu chelate is used, the Mg increases the natural resistance of the plants to fungal attack.

Title: Modulation detector for measurement of modulation characteristics - applies to radio signal using comparatorroorottor and array of synchroniser demodulators
Inventor: GARNIER GERARD
IPC: G01R29/06
Filed: 1975-04-28
Abstract: The modulation detector precisely measures the modulation characteristics of a radio signal whose amplitude and modulation vary in time. The product is formed between the FM input signal and another FM sinusoidal signal. The product is compared with another FM signal in a comparator to produce an error signal. This error signal is the result of comparing the magnitude of the frequency excursion and modulation phase of the two input signals which have the same modulation frequency. This error signal is applied to a series of synchroniser demodulators each supplied with a local oscillator frequency that allows the carrier to be eliminated.

Suction rotors (206) can be mounted inside the outer impeller wall near the blade leading edges.
Patent FR-2320834-A1 (FR)
Title: Printing high density information using a laser beam - scanning a matrix horizontally in synchronism with a line scanned original e.g. for 'video film'
Inventor: BEYRARD NORBERT ROGER
IPC: G03F7/039
Filed: 1975-08-11
Abstract: High density information is printed on a print carrier by modulating a beam of coherent light in a first cell with a signal which represents the information to be printed and focussing the light beam in a deflection cell for the line-type scanning of the print carrier. Advantageously, the modulation signal is an electro-optical signal, obtd. by scanning an original, the line-type scanning of the print carrier being synchronised with the scanning of the original. The device permits the reproduction high density information on photographically recorded substrates or printing substrates in large numbers of prints at low unit cost. The process simplifies the reproduction of 'image plates' and 'video films', e.g. for recording of complete television programmes, and can also be used for storage of information for computers etc.

Title: Helmet protecting eyes and lungs against noxious gases - has lever on chin strap to operate pump pulling air through filter to prevent lung strain
IPC: A62B17/04
Filed: 1975-09-16
Abstract: The helmet protects the eyes and lungs against noxious gases. It comprises a plastic shell strapped on top of the head and a similar mobile portion attached to it by bellows. This forms a pump, operated by a lever and chin strap. Opening the mouth to breathe pumps air into the space inside the helmet. Closing the mouth separates the pump halves, being spring biased, and air is drawn through the filter in the upper part of the helmet. Used air is expelled through the neck seal. The action prevents strain on the lungs when pulling air through the filter.

Title: IC engine exhaust pipe - has venturi nozzle at end to cool gases by drawing in ambient air
IPC: F01N1/00
Filed: 1977-03-09
Abstract: The exhaust pipe of a vehicle internal combustion engine terminates in an injector nozzle working on the Venturi principle. This nozzle termination is installed downstream of the exhaust silencer. The nozzle is surrounded by an outer tube (T) which is open at the inlet end (b1) to atmosphere. The Venturi effect of the nozzle draws cold ambient air through the outer tube and as this flows over the nozzle (A) it cools the exhaust gas. The drop in pressure resulting from the cooling sets up a pressure difference between the engine and the end of the exhaust which forces exhaust gases out of the engine more effectively than the motion of the engine pistons by itself. This improves the performance of the engine.
