Abstract: Inter alia HCN is made by ammoxidation of methyl or ethyl formate or acetate, formaldehyde or acetaldehyde, acetone or methyl ethyl ketone in the presence of specially prepared V and Sn oxides having a surface area of 50-500 sq. m./gm.ALSO:Specially prepared catalysts having a surface area of 50-500 sq. m/gm. and containing vanadium and tin oxides are used in oxidizing ketones, aldehydes, esters, toluene, xylenes or olefins having 3 or 4 C with oxygen, ammonia and optionally steam to the corresponding nitrile.  Reference is made to the production of benzonitrile (ex toluene), terephthalic dinitrile (ex p-xylene) and acrylonitrile (ex propylene). Acetonitrile from methyl or ethyl acetate, acetaldehyde acetone and methylethyl ketone is also described.ALSO:V and Su oxide catalists having a specific surface area of 50 to 500 sq. in/gm. are made by dissolving Su in 10-40% HNO3 at all temperature not exceeding 20 DEG C., adding the resulting clear solution to an aqueous celloidal Hi SiO3 sel containing 8-20% Si O2 and NH4VO3 (optionally also H3PO4), homogenising the resulting suspension and treating with aqueous NH3 at 80-95 DEG C., for 0.5-10 hours, drying and calcining at 400-800 DEG C., and ultimately treating at 110-500 DEG C., per 1-50 hours with steam, gaseous ammonia and optionally air.  Other elements which may be present are Ba, Al, Ti, W, Sb, Cr and Pb.  Comparative examples are given.

Title: Method and apparatus for separating lighter and heavier portions of threshed tobacco
IPC: A24B3/16
Filed: 1976-09-09
Abstract: 1505946 Pneumatic separating AMF INC 9 Sept 1976 [28 May 1976] 37468/76 Heading B2H  Threshed tobacco is separated into lighter and heavier fractions by introducing it into a chamber 30 containing two adjacent vortices VA and VB circulating in opposite directions and coacting to form a rising column of air which carries off the said lighter fraction through an outlet 38. The heavy fraction falls to the bottom of the chamber and is carried away by a stream of air flowing along a duct 39. The tobacco is introduced into the chamber through an inlet 31 and air is blown into the chamber through opposed inlets 34 and 35. Each inlet 34 and 35 comprises a plate 40 provided with rows of ports 41. A slidable plate 42 having openings 43 is provided for each row of ports 41 to control the flow of air therethrough. Adjustable vanes 44 in the chamber adjacent the plate 40 control the direction in which the air enters the chamber. Air may also be introduced to or withdrawn from the chamber 30 through a valve 26 to prevent interaction between the air flows and pressure in the chamber 30 and the air flow and pressure in the duct 39. The air removed through the outlet 38 is recirculated to the inlets 34 and 35 by a blower (15) after removal of the tobacco therefrom. A portion of the output of the blower (15) may be bled-off through a pipe (18) and a blower (20), Fig. 1 (not shown).

Filed: 1964-09-23
Abstract: Permanent magnet alloys consisting of, in percentage by weight <TABS:1087064/C6-C7/1> and which may have been produced either by sintering or casting are heat-treated to precipitate fine ferro-magnetic particles of zeta-phase in a non-magnetic matrix of epsilon-phase.  The heat treatment may consist of  (a) chill casting the alloy and subsequently heating it to a temperature above 200 DEG C.  (b) solution treating the alloy, quenching, and subsequently heating to a temperature above 200 DEG C.  (c) cooling the alloy, either immediately following casting or from the solution treatment temperature, at such a rate that the desired precipitate is formed. As exemplified solution treatment is carried out at 1180 DEG -1400 DEG C. and precipitation treatment at 400 DEG -800 DEG C. for 30 minutes to 300 hours.  In the production of the alloys by sintering, powdered alloys containing 70% Co/30%Al, 70% Co/15% Al/ 15%V, and 55% Co/3% Al/40% Sn were first prepared; to these powders as appropriate were added metal powders to obtain the desired composition. Ether was added and, after mixing, the powders were moulded at about 18 tons/sq. in. for 10 seconds, after which the resulting compacts were sintered at 1300 DEG -1380 DEG F. for 1 to 3 hours.

Abstract: Chlorinated aliphatic hydrocarbons are prepared by reacting at elevated temperatures in the gaseous state an aliphatic hydrocarbon containing 1-4 carbon atoms and/or a partially chlorinated derivative thereof with chlorine and/or hydrogen chloride and an oxygen-containing gas in a metal halide catalyst zone, continuously removing and analysing the product gases to determine the elemental oxygen content thereof, and adjusting the feed rates of the gases fed to the catalyst zone in response to the analysis so as to provide in the product gases an elemental oxygen content of 0,02-5% by volume. Partially chlorinated derivatives and non-chlorinated saturated and unsaturated hydrocarbons may be recycled.  The oxygen-containing gas may be oxygen alone or with a diluent e.g. nitrogen, argon or neon, or air.  Preferably 0,5-5 moles of chlorinating agent are supplied to the reactor per mole of hydrocarbon or partially chlorinated hydrocarbon, and 0,8-1,5 moles of oxygen per mole of chlorinating agent.  Preferred catalysts are copper, chromium or iron halides, with or without, a halide of another metal, e.g. sodium or potassium, and may be impregnated on an inert carrier. The preferred reaction temperature is 350 DEG -700 DEG  C.  The adjustments to the feed rates may be made automatically in response to the analysis of the product gases.
