Classes 23 and 59  In a classifier having a rotor comprising a series of spaced annular plates 9 intersided by generally radiating blades 10, the finer particles are entrained in an air current which flows inwardly through the rotor periphery and which is discharged axially from the rotor. The classifier and a rotary mill occupy the upper and lower parts of a cylindrical housing 1 (Fig. 1) on which is mounted a fan housing 3. A shaft 2 carries a fan 4 for drawing the air current through the rotor, the classifier rotor, and the mill rotor 5. The mill rotor comprises vertical blades held in slotted discs between further discs, and a fan 6. The particles are fed to the mill through an inlet 7, and an air flow through the bottom of the housing is induced by the fan 6. The finer particles from the mill pass to the classifier through a gap between the housing and a rotary plate 8 supporting the classifier rotor. Finer particles pass through the classifier rotor to be discharged by the fan 4 whilst coarser particles rejected by the rotor are returned to the mill. In the modification shown in Fig. 6, the classifier rotor and a fan (not shown) are mounted on a horizontal shaft 21 in a housing 19 mounted above a housing 13 containing a milling or separating rotor comprising a series of discs connected by rods 18 and mounted on a shaft 17.

Title: Improvements in and relating to the formation of phosphate coatings
IPC: C23C22/22
Filed: 1956-04-09
Abstract: Iron, steel, zinc and aluminium surfaces are given fine-grained nodular phosphate coatings by treating with an aqueous acidic solution containing 0.05 to 1.5% (wt/vol) Zn, 0.012 to 7.5% Ca, the weight ratio of Ca to Zn being 0.25 to 5.0; phosphate ions and an oxidizing agent, the ratio of oxidant to phosphate ions being equivalent in effect on the rate of coating formation to a ratio of nitrate ions to phosphate ions of 0.2 to 5.0 by weight. A nitrate is the preferred oxidant but others may be a chlorate, nitrate, m-nitrobenzene sulphonate, hydrogen peroxide, dinitrobenzene sulphonate, bromate iodate, picric acid, t-butyl hydrogen peroxide or quinnone, or mixtures thereof.  Equivalent ratios are said to be 0.02 to 2.0 for chlorate, 0.004 to 0.05 for nitrite, 0.06 to 3.0 for m-nitrobenzene sulphonate, 0.0008 to 0.01 for H2O2, 0.04 to 1.5 for dinitrobenzene sulphonate; for other oxidants and for mixtures the equivalent of the nitrate to phosphate ion ratio of 0.2 to 5.0 may be determined by trial. Chloride ions may be added if nitrate is not the oxidant.  The Ca may be added as oxide, by dioxide, chloide, mono- or di-hydrogen phosphate, but preferably as nitrate.  When nitrate or chlorate (or both) is the oxidant the ratio of Ca ion to NO3 and/or ClO3 ion should be 0.1 to 0.3 by weight; and generally the amount of Ca should increase with amount of oxidant.  A replenishing mixture or concentrated aqueous solution contains Zn, Ca and PO4 radicals or ions, the ratio of Ca to Zn by weight being 0.06 to 1.4 and of Zn to PO4 being 0.2 to 0.4. The phosphated surface may be rinsed in hot water followed by aqueous chromic acid containing e.g. 0.7 gm/litre, and finally oiled, then if desired painted.

In a modification the loading arm 37 is pivoted to the cantilever so that it can turn through 90 degrees in passing from the loading station to the moulding station, whereas the cantilever passes through about 75 degrees to reach the unloading station which is not directly opposite the loading station.
Patent GB-732602-A (GB)
Title: Improvement in feeding solid granular material
IPC: B01J8/12
Filed: 1953-04-21
Abstract: In a process in which granular solid material is transferred between a zone at low pressure and a zone at high pressure and both zones are maintained in continuous open communication, one with the other, excessive gas transfer between the zones is prevented by maintaining an upwardly extending column of material in the path between the zones, the upper end of the column being maintained at about the pressure <PICT:0732602/III/1> <PICT:0732602/III/2> of the low pressure zone and the lower end at about the pressure of the high pressure zone, the pressure drop per foot of column height being at least sufficient to disrupt the compactness of the column, and maintaining on top of the column a bed of material of sufficient cross-section to effect a reduction of the upward gas velocity below the critical velocity and of sufficient depth to maintain the column in compacted form throughout its length. The process may be used in a variety of hydrocarbon conversion processes, such as catalytic cracking, reforming, desulfurization, coking, hydrogenation and dehydrogenation in which solid granular material is transferred through a cyclic path.  The catalyst passes into the converter 10, Fig. 2, through hoppers 30, 34, the latter of which may be placed under pressure by setting the three-way valve 36 to bring the high pressure gas line 37 into communication with the pipe 38.  When the valve is turned to connect the pipe 38 to exhaust 39, the catalyst flows from the hopper 30 through the short conduit 40 to the hopper 34.  When this hopper is full, the valve 36 is adjusted automatically to increase the pressure in the hopper to a value approximating that in the converter 10.  When this occurs, gas flows upwardly through the catalyst in the conduit 40 and the pressure drop across this conduit is higher than that required to disrupt the column and blow it upwardly and out of the conduit 40.  Since the bed of solids in the hopper 30 at the upper end of the conduit 40 is of increased horizontal cross-section, the upward velocity of the gas is reduced to less than that which is sufficient to disrupt the bed of catalyst. The height of the catalyst above the critical level is sufficient for the downward force at the critical level to be at least sufficient to overcome the upward force at that level caused by the rising gas. The hopper 34 is expanded similarly to the hopper 30 so that there is maintained on top of the column of catalyst in the conduit 43 sufficient material to keep the catalyst in compact static condition. In a modification a series of concentric conduits 60, 61 is inserted in the conduit 40 and a grid, or grids, 62 is placed across the hopper.  The baffles 70, 71, however, may be conical and of different slopes. Vertical drain spouts 72, 73 are provided at their lower ends. Specification 590,425 is referred to.

Abstract: 768,611. Photographic flash devices. SYLVANIA ELECTRIC PRODUCTS, Inc. April 15; 1955; No. 10973/55. Class 9 (2). Photographic flashlight apparatus comprises a battery casing 10 on whichis mounted a magazine 22 and a reflector 30 together with mechanism for flashing the lamps and further mechanism for ejecting a spent lamp24<SP>1</SP> from the fixing position and feeding a fresh lamp 24 from the magazine to the firing position. The magazine 22 is integral with an insulating member19 in whichis mounteda contact 18 for the battery. A clip 20 charged with'lamps 24 is inserted in the magazine 22 so that an opening in the front wall 21 is aligned with an opening in the reflector, the lamps being urged downwardly by a presser 28 stressed by a spring 27. Near the outlet of the clip is a baffle 17 to guide the foremost lamp, Fig. 2, to the ejection position, where it rests on a carriage 33 extending through a slot 29 in the bottom wall of the clip. Extending upwardly from the back of the carriage is a finger 35 which engages the back of the lamp -34 to pull the lamp into the flashing position when a trigger mechanism is actuated. The trigger mechanism 'comprises a spring- stressed grip 40 mounted in guide rails 42; 44 and connected by an arm 50 to a spring clamp 52 for holding the bulbs in the flashing position. The clamp 52 is of metal and has two arms 54, 56, the rear arm 56 making electric contact with the base of the lamp 24, the arm 56 being in circuit with the arm 50 and spring 46 connected to the casing 10. The circuit to the lamp is completed by depressing a plunger 60 and spring 62 connected to the contact 18 so that a finger 45 on the plunger forces a contact spring 64 secured to the grip 40 against the centre contact of the lamp. The carriage 33 is connected by a flexible member 70, slotted to allow passage of the contact spring 64, to the grip 40, so that by pressing the grip against the action of its springs 46, 48, and hence retracting the arms 54, 56 towards a bulb at the bottom of the clip, the carriage 33 moves forwardly and the bulb on the carriage forces the spent bulb out of the arms 54, 56. Thereupon the bulb on the carriage passes into the arms 54, 56 and as the hold on the grip is relaxed the arms 54, 56 return to the flashing position.
