Title: Improvements in method of making sulphur trioxide
IPC: C01B17/79
Filed: 1930-05-13
Abstract: A catalyst for the manufacture of sulphur trioxide from sulphur dioxide and oxygen consists of a mixture of a vanadium and a rubidium compound.  The amount of rubidium in the mass may be increased up to the point at which it is atomically three times that of the vanadium; a preferred composition is one in which the amounts of the two components are atomically equal.  According to an example, a carrier, such as celite chips calcined at about 1000 DEG  C., is immersed in an aqueous solution of ammonium meta-vanadate.  When saturated, the carrier is removed and dried at 110 DEG  C.  This operation is repeated until all the solution has been absorbed.  An aqueous solution of rubidium chloride is then applied by sprinkling, and after saturation, the carrier is again dried at 110 DEG  C.  It is preferable to heat the catalyst thus prepared to about 500 DEG  C. in an atmosphere containing sulphur dioxide before use.  Other soluble rubidium and vanadium compounds may be used, together with salts such as rubidium vanadate, and the solutions may be applied to the carrier either separately or mixed together.  In the manufacture of sulphuric acid, the heat evolved in the converter is removed, so that the temperature of the gas in contact with the catalyst is about 420 DEG C.

Abstract: 914,881. Refuse-burning stoves. SILENT GLOW OIL BURNER CORPORATION. April 29, 1960, No. 15237/60. Class 126. An incinerator comprises a combustion chamber to which a limited supply of air is admitted, an ash-settling chamber and a passage connecting the two chambers to which air is also admitted to continue combustion of gases distilled in the combustion chamber. As shown, Fig. 7, refuse is charged into a chamber 1 and burnt in air supplied through apertures 63. Apertures 61 through which additional combustion air is admitted adjacent the passage 43 ensure that combustible gases distilled in the chamber 1 enter the passage 43 through apertures 39 in an ignited condition. Further air admitted through apertures 57 and a single row of larger apertures (not shown) between the apertures 61 and 57 causes complete combustion of the combustible gases and any smoke-forming particles carried thereby. Gaseous combustion products and ash enter the chamber 3 through apertures 41 and are drawn through air opening 69 in a perforated plate 65 or, in high flame conditions, through the perforations 67 to a stack 23 and thence to atmosphere. When the charge has been combusted to a degree that the combustion gases produced are insufficient to maintain the draught in the stack 23, the draught through the drum 1 is automatically reversed and the drum 1 acts as the stack. The charge is preferably lit by holding burning tapers, passed through a hinged door 73 in the passage 43, against apertures 39. Preferred dimensions are given for the components of the incinerator, the apertures and the spaces between the apertures. Specification 914,882 is referred to.

[Also in Division F1] An arrangement for preventing slip of vehicle road wheels 15 driven through changespeed gearing 12 by an internal combustion engine 10 whose output can be controlled by a regulating member 16 (e.g. carburetter throttle or injection pump control) operable by an actuating member 17 (e.g. accelerator pedal) comprises a pulse transmitter 18 arranged to be responsive to rotational acceleration in the driving train between the wheels and the gearing and connected to a corrective element, solenoid 28, which is connected to linkage between the actuating and regulating members and, when a pulse is transmitted upon a predetermined acceleration being exceeded, acts upon the linkage to reduce the engine output. The corrective element may act variably (e.g. via an electronic circuit), or may act to return the regulating member to zero. The solenoid 28 acts on a first linkage part 31 which is biased by spring 32 against a second linkage part 34. The pulse transmitter may be associated with a cardan shaft or, as shown, one positioned in each of the wheel hubs. In the latter ease the transmitters are associated with the corrective element through a collective circuit such that the element will respond to whichever transmitter happens to be sensing the maximum acceleration. The pulse transmitter is connected to a change-over switch 21 by which the transmitter can be connected to the corrective element 28 or to a brake-slip regulator 23. As shown, the switch 21 is biased towards a brake-slip regulator contact until the member 17 is operated to close a switch 24 to change over the switch 21. Alternatively switch 21 is associated with a brake pedal such that when operated, the pulse transmitter 18 is switched from being connected to the solenoid 28 to being connected to the brake-slip regulator 23. A manual clutch 11 and gearbox 12, shown, could be replaced by an automatic speed-change gearing for example in conjunction with a hydrodynamic clutch, or torque converter.
