Filed: 1974-11-21
Abstract: A continuous process for removing nitrates from nitrate containing aqueous solutions having a pH of about 0-7, which comprises: (1) extracting the nitrate containing aqueous solution with an organic amine salt dissolved in an organic solvent phase whereby the nitrate ion goes into the organic solvent, (2) separating the organic phase, (3) stripping the organic extraction solvent phase from the extraction with a stripping salt solution of pH at least 0.5, said salt being capable of ion exchange with the nitrate ion and containing the anion of the amine salt in step (1) to strip and convert the amine for the next extraction cycle into the same amine salt as used for the extraction and the stripping solution contains the nitrate ion and the cation of the stripping solution (4) maintaining the concentration of the salt formed by the cation of the stripping salt and the nitrate anion in the stripping solution so high that this salt is crystallized from the stripping solution substantially continuously, but still so low that the nitrate anion extracted into the organic extraction solvent phase passes during the stripping continuously into the stripping solution while the anion of the stripping salt passes from the stripping solution into the organic extraction solvent phase and recovering crystallized nitrate salt from the stripping solution.

Title: Decanter for purifying water contg. particulate materials - incorporates scraper which can be lifted clear of deposited mud, facilitating starting after prolonged stoppage
IPC: B01D21/00
Filed: 1978-06-22
Abstract: A decanter, consisting of a decantation tank and a scraper driven axially to circulate decanted mud from the periphery of the tank to the centre where it is discharged, incorporates means of raising or lowering the scraper, pref. independent of its means of rotation, and such that the rate of lifting is considerably greater than that of lowering. Used partic. for the purificn. of water which has been used to wash material extracted from quarries and sand-pits or coal or mineral mines. Process facilitates starting of the scraper after a prolonged stoppage resulting in a thick layer of mud. The scraper can be raised out of the layer, then started up and lowered so that it enters the mud in a very progressive manner until it comes back to its normal operating regime. Decanter may be used when decantation gives rise to the formation of dense muds, e.g. in sugar refining, in the cases when a flocculating agent is made heavy by a flocculant and in the case where a ppte. is formed by crystallisation in a liq. medium other than water.

Title: Control valve for fluid-operated clutch
IPC: F01P7/16
Filed: 1981-02-06
Abstract: A control valve is provided for a fluid-operated clutch. Specifically, the control valve controls fluid to the fluid-operated clutch of a vehicle cooling fan. The control valve disengages the clutch to disconnect the fan from an internal combustion engine of the vehicle when coolant temperature is low and engages the clutch to operate the fan when the coolant temperature rises to a predetermined value. The control valve has a central passage with three bores and a valve spool with three sealing members associated with the bores. Fluid is supplied under pressure to the valve and always acts in opposite directions on two of the sealing members to provide a balanced condition for the valve spool even with fluctuations in the inlet pressure of the fluid. The control valve utilizes a temperature-responsive device to move the valve spool, with the device being readily adjustable to achieve operation at desired coolant temperatures.

IPC: B60T13/14
Filed: 1981-04-23
Abstract: A booster for a vehicle braking system has an input piston, a boost piston and an output piston working a bore, the boost piston being advanced in the bore in response to pressure fluid from a source pressurizing a boost chamber under control of a valve. The operation of the valve is dependent on the pressure in the system, and the valve has a valve mechanism working in a bore in the boost piston of which one part has a pressure-responsive face, the valve being operative, on initial movement of the input piston to cause pressurization of the braking system to the threshold level, and application of pressure fluid to the pressure-responsive face to move the part relative to the input piston to place the boost chamber in communication with the pressure source. Threshold pressurization of the braking system may be achieved by pressurization of the boost chamber, or an auxiliary chamber forward of the boost piston to a predetermined level.
