Title: Regeneration of synthetic gel catalysts
IPC: B01J21/20
Filed: 1961-03-28
Abstract: A method for removing poisoning metal comprises vanadium from a synthetic gel silica-based hydrocarbon conversion catalyst comprises regenerating the catalyst to a substantially carbon-free condition and treating the regenerated catalyst with a gas containing molecular oxygen at at least 1000  DEG F., and removing at least the vanadium from the catalyst.  The treatment with O2 may be carried out using air at 1150-1600  DEG F. which temperature may be at least 50  DEG F. higher than the regeneration temperature.  The vanadium may be removed by treatment with a basic aqueous solution containing ammonium ions, e.g. an NA4OH solution of pH 8-11.  Both nickel and iron may also be removed.  If desired, the oxygen-containing gas treatment may be followed by treatment at elevated temperature with a gas reactive with vanadium (as well as nickel and iron), e.g. a chlorinating or sulphonating gas, preceded by a sulphiding treatment if necessary.  Treatment with CO may also be used to remove nickel and some iron poisons.  The process is especially suitable for catalysts employed in fluidized bed systems.  The two specified catalysts are composed essentially of silica and contain 13% and 25% respectively Al2O3.  Examples are given.  Specifications 936,116 and 971,551 are referred to.

Abstract: 1,250,535. Fruit beverages. ASTRA-WALLCO A.B. March 3, 1969 [Dec. 4, 1968], No.11323/69. Heading C6E. A dry powder for preparing juices having fruit flavour when dissolved in an aqueous medium, the fruit flavour having substantially the same intensity and duration as the flavour of the corresponding natural fruit juice, comprises at least one flavouring agent, colouring agent and sweetening agent, and a buffering system comprising at least one polybasic acid and at least one alkali metal (sodium or potassium) or calcium salt of a polybasic acid, and the buffering capacity of the system is such that when the powder is dissolved in a predetermined volume of the aqueous medium and the resulting juice is consumed, a decrease in pH around the gustatory nerves is produced, and the duration of the decrease is substantially the same as that produced by the corresponding natural fruit juice. The amount of the buffering system present is such that the PH of the aqueous medium is reduced to 2.5 to 4.5. Buffering acids: adipic, citric, fumaric, maleic, succinic and tartaric acids. The ratio of acid to salt is 1.5:1 to 10:1. Part of the acid and/or salt may be replaced by alkali metal carbonate in order to provide carbonated beverages. A typical formulation contains anhydrous citric acid, anhydrous trisodium citrate, ascorbic acid, sodium cyclamate, sodium saccharin and calcium phosphate together with food colours and orange aroma. Lemon, lime, apple, strawberry, raspberry, blueberry and gooseberry aromas are also mentioned. The formulations may also contain sugar, gluconic acid, polysaccharides, carboxymethyl cellulose, carragheenins, sodium alginate, esters of alginic acid and gum tragacanth.

IPC: B24D15/08
Filed: 1916-08-11
Abstract: 108,531. Vincent, H. A. Aug. 11, 1916. Stropping-apparatus.-Relates to devices for sharpening safety-razor blades of the kind in which the blade-holder is automatically rocked at each end of the stroke to reverse the blade and in which provision is made for both honing and stropping with the same device, such that the blade may be caused to travel back foremost over a strop and edge foremost over a hone. According to the invention, the hone is or may be disposed on one side of the axis on which the blade rocks and the strop on the other. The apparatus consists of a rectangular frame which may be closed in on one side by the hone and on the other by the strop; one of them is removed while the other is in use. On the hone side of the frame are formed two longitudinal flanges 17 serving as rails for the rollers 14 on the ends of the blade-holder which is placed in slots 15 in a frame 9 adapted to be moved by hand to and fro in the outer frame; the rollers are pressed upon the rail by springs located in the slots. When the strop is in use, Fig. 3, the rail is at the top and the axis of the bladeholder is between the strop and the rail; when the hone is in use, the hone surface and the rails are on the same side of the axis. Instead of plain rails and friction rollers, use may be made of racks and pinions and a friction coupling to the axis of the blade-holder. The razor blade may be formed with a central stem 21, having a notch on each side, adapted to enter a hole in the holder spindle 13 and to be retained therein by a spring device 22 engaging the notches.

Title: Permanent magnets
Inventor: BLUME WALTER S
IPC: H01F1/113
Filed: 1959-04-03
Abstract: 870,573. Moulding magnets. LEYMAN CORPORATION. April 3, 1959, No. 11409/59. Class 87(2). [Also in Group XXXV] A magnet is made by suspending ferrite particles in a liquid whose viscosity is not greater than that of water, applying a magnetic field to orientate the particles, separating the liquid from the particles, and causing a matrix material to solidify around the particles. In one method, (Fig. 1) a suspension of ferrite particles in acetone is introduced into a non magnetic die 2 provided with movable punches 3, 4 which act as pole pieces and provide the magnetic field. The punches move together to expel the acetone whilst the field is applied and the remaining mass is removed and impregnated with molten chlorinated naphthalene which on cooling forms a solid matrix. The mass is then subjected to an ionising operation in the die under moderate temperature and pressure and allowed to cool. In a second method a die with a cavity 5, Fig. 3, is utilised, the matrix material being forced through ports 6, 7. A high frequency electrode surrounding the die may be employed to set a matrix material of the thermosetting type. In a further method a co-dispersion of ferrite particles and matrix material, e.g. lead ferrite and polystyrene dispersed in alcohol is compressed in a die in a magnetic field and heated to 400‹F. when the residual alcohol evaporates and the polystyrene softens. The mass is then further compressed and cooled. The ferrite material may be lead, barium or strontium ferrite and may be prepared by specified methods to yield single domain particles having a size between ¢ and 10. The dispersion liquid may be water, alcohol, acetone, benzene, xylene or toluene and the matrix material may be epoxy, acrylic, polyester or phenolic resins, ureaformaldehyde cellulose acetate, polyethylene or metal.
