Title: Process for the treatment of fly ash containing vanadium
IPC: C22B7/02
Filed: 1973-06-08
Abstract: 1414418 Vanadium pentoxide; vanadates SOC FRANCAISE D'ELECTROMETALLURGIE 8 June 1973 [9 June 1972] 27445/73 Heading C1A A process for the treatment of fly ash derived from petroleum or bituminous products to recover ranadium by the formation of a soluble ranadate, comprises reacting ash with NaOH solution containing 1-5 moles Na 2 O/litre for a period of 4-8 hours at a temperature of above 50‹ C., and adding to the reaction mixture a quantity of CaO corresponding to 6-40% by wt of the SiO 2  contained in the ash. The process is based on firstly, the selective solubilization of V and SiO 2  in NaOH solution, e.g. when ash containing 2% V 2 O 5 , 18% SiO 2 , 10% Al 2 O 3 , 4% Fe 2 O 3  and 60% C is treated at 90‹ C. with 2À5 N. NaOH solution for 6 hours 85% of the V and only 7% of the SiO 2  is solubilized, and secondly on either the progressive addition of CaO during the above reaction or preferably the addition of CaO all at once towards the end of the reaction (e.g. 15-30 mins. before filtering off the insoluble residue). The addition under these conditions of CaO causes the sodium silico-aluminates to be replaced by Ca silica aluminates and nearly all the sodium silicate to be precipitated as calcium silicate whilst losing little of the ranadium from the solution as insoluble calcium randate. Recovery of the ranadium as V 2 O 5  is carried out by heating the solution of sodium ranadate with excess CaO to precipitate calcium ranadate, which is then converted into ammonium rancidate and hence V 2 O 5  in the usual manner. It is preferred to operate the process continuously.

Patent GB-658777-A (GB)
Title: Improvements in the manufacture of film-forming substances in powderable or granularform
Inventor: DOWNING JOHN
IPC: C08B11/20
Filed: 1948-10-22
Abstract: Film-forming materials are heated to a temperature such that they sinter but do not char by a process in which at least the greater part of the necessary heat is produced in the material by means of mechanical pressure combined with shearing action, whereby the products are converted into a more easily powdered or granulated form.  The process may be applied to fibrous water-soluble methyl cellulose, fibrous hydroxyethyl cellulose, methyl ethyl cellulose, water-soluble and other ethyl celluloses, sodium carboxymethyl cellulose, and also to other cellulose derivatives and film-forming substances which have not a strictly fibrous structure.  The process is preferably carried out by passing the substance several times between closely-spaced hard-surfaced rolls with friction at the nip. Suitable rolls are those used for working rubber; they may be arranged so that the circumferential speed of one is up to twice that of the other. The nip under zero load is preferably about 0.01-0.03 inch. Preferably the rolls are heated to 50-100 DEG  C.  The methyl cellulose may be dried at 50-100 DEG  C., or it may contain an equilibrium amount of water or it may have been wetted with water or an organic liquid.  The presence of 10-35 per cent (preferably 12-20 per cent) of water is desirable.  Any additions to it should not be such as to hinder the sintering action of the rolls. The resultant material is a brittle horny flake which can readily be pulverized, e.g. in a hammer-mill.  Reduction in viscosity is prevented by using cool rolls, working in the absence of oxygen, or by dispersing in the methyl cellulose prior to treatment a non-staining anti-oxidant such as hydroquinone or phenyl-b -naphthylamine.

Title: Improvements in and relating to road traffic signals
IPC: G08G1/09
Filed: 1934-09-26
Abstract: 440,906. Road signals for controlling traffic. KENT, A. F., Lee Moor, Cornwood, Devon. Sept. 26, 1934, No. 27577. [Class 118 (ii)] A pedestrian-controlled road-traffic signal comprises an arm which can be lowered from a vertical to a horizontal position, the sign on the arm changing as the horizontal is reached from a " caution " to a " stop " sign, the arm restoring slowly and being arranged so that re-operation is not possible until the signal is again vertical. The changing sign may be (i) a drum bearing red and green reflectors and adapted to be rotated to show red and green in rapid succession while descending to the horizontal position ; (ii) a prismatic unit having "slow" on two sides and " stop " on the other two which unit is rotated to present the "stop" signs to the traffic as the horizontal is reached or (iii) a " stop " sign normally hidden by a " slow sign, the " slow sign being held whilst the " stop sign is lowered to the horizontal as shown in the drawing. When the signal is at " stop " a "cross now " signal may be given to pedestrians. The sign may be fitted with internal illumination or with mirrors which reflect external light through the signs. As shown, when the " stop " signal is to be given the weighted or spring driven lever f is raised into the position shown either by handle l acting on pin m or by other suitable means. When the signal arm is vertical the cam c on lever a, which is rigidly connected to the signal arm spindle b, presses the pawl h anticlockwise against the action of spring j so that it engages pin d on lever a. The lever f restores slowly and as pawl h and pin d are engaged, the lever a is turned through 90‹ into the lower position shown dotted. Before reaching the horizontal position the " slow " signs are held and the " stop sign, which is normally hidden, moves alone into the horizontal position. When the lever a is in its lower position the cam c moves away from the pawl h so that the spring j swings the pawl clockwise and pin d is released. The lever a and the signal arm then restore slowly, the restoring power being supplied by a spring, whilst the action is delayed by a dashpot (not shown). Should the lever f be again lowered before the apparatus is normal the cam c will not move the pawl h into engagement with the pin d and the signal arm will not be affected.
