Title: Automatic gain control for television receiver - using signal referenced to black level avoids dependence on average brightness
IPC: H04N5/53
Filed: 1974-11-20
Abstract: The system described overcomes the problems of an AGC signal derived from the average voltage level of picture plus synchronisation information which varies with the average brightness of the picture as well as with the strength of the signal received. This is achieved by deriving a signal dependant upon the relative amplitudes of the fixed black level and the periodic synchronisation signal, and amplifying this to apply to the receiver I.F. stages. The method is applicable only to signals in which the synchronisation is provided by a pulse occuring below the black level of the image information.

Title: Concentric cylinder settlement device for water treatment - with right-and left-handed helical spirals in between
IPC: B01D21/00
Filed: 1974-12-26
Abstract: Settlement device, with a round cross-section, is intended for water-treatment plants; it comprises built-up baffle-plate elements through which the water passes before being purified. These elements consists of at least two cylindrical concentric tubes with helical blades arranged between them. The blades make an angle of about 60 degrees with the horizontal; they are delimited in the radial direction by another cylinder, so as to form five separate circulation paths. These paths are swept by slow ascending currents of water charged with solid particles; these descend on the surfaces of the blades by gravity which surmounts the ascensional forces and allows the particles to slide towards the base along the helical surfaces to a collector. The water from which the solids have at least been partially eliminated leave by the top of the device, possibly to undergo a complementary treatment. The helical surfaces, which are only illustrated between two internal cylinders, are alternately right- and left-handed. The cylindrical shape allows the whole of the area of the device to be used as a settling area as compared with existing rectangular tanks; more efficient operation is thus attained. The device can be made from plastic materials e.g. polyethylene or from metals e.g. steel.

Title: Particle flux dosimetry - by subjecting nuclear emulsion plate to flux, developing and estimating metallic silver by activation
Inventor: FRANCOIS HENRI
IPC: G01T1/08
Filed: 1976-06-25
Abstract: Particle flux dosimetry comprises subjecting to the flux a nuclear emulsion plate carrying a gelatine emulsion contg. microcrystals of silver bromide. The plate is then developed and the quantity of silver reduced to the metallic state is determined by activation. When the flux is of non-ionising particles e.g. neutrons, the emulsion is doped with a substance which gives a secondary ionising reaction under the effect of neutrons. Method avoids the problems associated with photometric and microscopic methods, e.g. the long times needed and the difficulties of measurement. It allows the overall dose to be defined and in addn. the spectrum of this does as a function of the different energy bands of the particles. It has a wide range of sensitivity.

Patent FR-2373630-A1 (FR)
Title: Washing machine outlet - with controlled washing liquid discharge device
IPC: D06F39/08
Filed: 1976-12-07
Abstract: The liquid discharge device may be applied to the drainage of wash liquors from domestic washing machines. The device comprises a tube connected to the outlet pipe of the machine at one end, and to the discharge conduit at the other by means of a flange joining. The tube is disposed coaxially within a second tube, closed by covers at its two ends, and has two siphon holes inserted near its two ends but within the covers. When the outlet pipe is fitted to a tube leading to the discharge conduit, if the capacity of the washing machine pump is greater than that of the discharge arrangements, there may be the risk of backflow, and possibly of overflow. On the other hand, where the outlet pipe is joined to a tube leading to the discharge conduit by means of a grooved nozzle, an air intake valve must necessarily be fitted, which increases the cost and provides a weak point, subject to wear and corrosion by the wash liquors. The device of the invention provides an improvement on known arrangements.
