Patent GB-648386-A (GB)
Title: Oxidation of olefines
Filed: 1947-06-21
Abstract: Methacrolein is produced by oxidizing isobutene catalytically with molecular oxygen at temperatures between 180 DEG  and 400 DEG  C. in the presence of a contact material comprising initially elementary selenium and copper and/or oxide of copper.  Selenium may be introduced in the elementary form or as a selenide which preferably only dissociates to a moderate extent under the reaction conditions, e.g. selenides of silver, antimony, cobalt and lead though copper selenide is also mentioned, or may be introduced as a vapour.  The activity of the contact material may be restored by introducing selenium vapour into the reaction zone. Asbestos, pumice and silica may be used as supports.  The oxygen may be diluted with such inert gases as carbon dioxide, nitrogen or steam to avoid explosion.  In an example a mixture containing isobutane and air is passed over heated selenium and then through a heated "Pyrex" (Registered Trade Mark) tube containing a contact material prepared by impregnating pumice granules with copper oxide, moistening the prepared granules with water and agitating them with selenium powder until uniformly coated. a -Methacrolein is obtained by fractional distillation of an aqueous solution obtained by scrubbing the products with water or by freezing the solution.  Selenium which condenses in the cooler part of the tube may be used again by reversing the direction of the gas flow and moving the heaters to heat that part of the tube. Silver, preferably in small amounts, may be used together with the copper component and a contact mass is prepared by soaking the carrier material with a solution of copper nitrate and silver nitrate and subsequently treating the charged material as described above.  Specification 625,330 is referred to.ALSO:A catalytic material comprising elementary selenium and copper and/or an oxide of copper is used for oxidizing isobutene to methacrolein.

Abstract: 744,086. Steering vehicles. AVELING- BARFORD, Ltd. June 21, 1954 [June 17, 1953], No. 16715/53. Class 79 (5). A steering system for a vehicle comprises, in combination with a vehicle chassis, a turntable rotable about an axis vertical to the chassis on which is mounted a seat 7 and a steering column 12 incorporating a steering shaft 13 and steering wheel 14, a transmission between the shaft 13 and the angularly deflectable axle or axles of the road wheels which includes a link 29 reciprocable endwise along the axis of rotation of the turntable, and including means whereby the sense of rotation of the axle or axles can be reversed for a given rotation of the steering shaft 13. The turntable comprises a hollow journal 1 supported in a boss 2 on a ball bearing 3 and the journal 1 carries the seat 7 on one side and a reduction gear box 10, which in turn supports the steering column 12 on the other side. The input shaft to the reduction gear 10 is keyed to a bevel wheel 17 engaging bevels 18 and 19 freely journalled on the shaft 13 and having splined portions 20 and 21 that can be selectively coupled to the shaft 13 by a dog clutch in which a sleeve 22, slidable on shaft 13, engages the splines 20 and 21 and is of such length that both splines can never be completely disengaged. The sleeve 22 is operated by a fork 23 carried by a rod 24 worked by an arm 42 pivoted to the gear box 10 by bolt 44. The rock shaft of the reduction gear carries a lever 27 connected by a ball and socket joint 28 to a link 29 which is similarly connected at its other end to a bell crank 32 controlling the axle or axles. To hold the turntable fixed to the chassis and to operate the dog clutch a spring-pressed bolt 33, Fig. 5, slides vertically in two bosses on gear box 10, one of which is shown at 35, and can engage diametrically opposite holes in the boss 2. The end of bolt 33 is formed with a spigot and shoulder such that when engaging one hole in the boss 2 the shoulder rests on the top surface of the boss 2 and in this position lever 42 connected to bolt 33 by bearing 43 holds the sleeve 22 coupled to bevel 19 and steering shaft 13. When the spigot is withdrawn from the hole, sleeve 22 is further engaged with bevel 19 and the turntable is free to rotate. The other hole in the boss 2 is of larger diameter to receive the shoulder of bolt 33 which due to its further downward movement can now rotate lever 42 anticlockwise to lift sleeve 22 and to couple the bevel 18 to the steering shaft 13. The bolt 33 can be lifted against the spring 36, by use of finger projections 49 at its head provided that in the reverse position a push button 50 is pushed into the head of bolt 33 to expel, by means of the inclined ramp 52, a holding plate 46 from a hole 48 in the bolt 33. Pedal controls for the vehicle may also be mounted on the turntable after the manner disclosed in Specification 515,911, or may be provided in duplicate outside the orbit of the turntable.
