Title: Continuous control process for flocculation plant - using centrifuge in conjuction with a turbidimeter
Inventor: SIBONY JACQUES
IPC: C02F1/52
Filed: 1975-01-28
Abstract: Continuous control of the operation of a plant for the flocculation of a liq. to be clarified consists in using a centrifuge, working continuously, on a fraction of the liq., the non-colloidal particles are eliminated and the remaining liq. is placed in a turbidimeter; the latter controls either an alarm system which operates when the colloidal turbidity attains a given value or an automatic regulating device for the dosing pump supplying the flocculant. When the turbidity increases beyond the admissible max., the dose is modified in proportion. The process can be used to ascertain at the start of flocculation whether all the colloidal particles are able to attain a size sufficient to allow them to settle. In addition the rate of addition of the flocculant can be adjusted continuously to ensure that all the colloids in the liq. are flocculated. The process can also be used for the adjustment of the amt. of dissolved oxygen in a biological treatment or for monitoring the pH value of the medium.

Title: Sol. matl. extn. from solids, e.g. for sugar beet - by countercurrent contact with liq. in compartmented rotating drum
IPC: C13B10/10
Filed: 1975-10-23
Abstract: A plant for extracting solid materials by countercurrent contact with a liq. incorporates a horizontal rotatable drum with an outer shell in which are an axial central cylindrical duct and two internal shells, one near the outer shell and one near the duct. Between the two internal shells are radial partitions extending the length of the drum and forming compartments, each in section a segment of a circle, the apex of which is at the axis. the internal shells and the partitions are permeable to liq. In the central duct a fixed support carries pipes which feed liq. to the compartments and carriers arms terminating in rollers which rotate against the inner surface of the duct. The drum has a cover at one end, in the form of a truncated cone, with a hole in the small apex through which liq. leaves and which determines the level of liq. in the drum, below the axis. At the large base of the cover is a screen with an opening in its lower part. Solids are charged to this opening by a pipe leading from a screw conveyor in a feed hopper, pass along the compartments, where sol. material is extracted, and are discharged by a screw conveyor at the outlet end. Method is esp. useful for extracting sugar from sugar beet or cane. The appts. is simpler in construction than existing plants and allows treatment of solid materials in relatively thin layers in compartments of which all the walls are filter surfaces and in which there is good contact between solid and liq. It allows of filling practically all the available vol. in the compartments, without risk of blockage during the flow.

Title: Radioactive decontamination by applying gel contg. decontaminant - then rinsing off or removing when dry
IPC: G21F9/00
Filed: 1977-02-09
Abstract: Radioactive decontamination of part is effected by applying a decontaminating gel to its surface, them removing it. The gel pref. has a viscosity of >=350 cP. It can be a glycerophthalic gel contg. a soln. of decontaminant, obtd. by reacting a 1:4 or 1:1 molar mixt. of phthalic anhydride and glycerol. Alternatively, it can be a glycerophosphoric gel, obtd. by reaction of an equimolar mixt. of glycerol and phosphoric acid; a cellulosic gel, e.g. obtd. by reaction of cellulose acetate, ethylene glycol, and acetic acid; a PVA gel; a silica gel, e.g. a silico-ethyl acetate gel; or an alumina gel. It can be applied by spray gun, and rinsed off with water, or allowed to dry and removed mechanically. The method overcomes the disadvantages of mechanical methods (which involve surface modification, and are difficult to apply to parts of complicated shape) and chemical methods (which lead to the production of large vols. of effluent and are difficult to apply to large parts). Low quantities of decontaminant are required, and the viscosity of the gel allows contact for the needed time for decontamination.
