Title: Improvements in and relating to the production of catalysts containing vanadium
Inventor: VINCENT GEORGE CLARKSON
IPC: B01J23/22
Filed: 1954-08-25
Abstract: A skeletal glass catalyst containing vanadium is prepared by fusing a mixture containing a vanadium compound, silica, boric oxide, and an alkali metal compound to produce a glass, heating to cause separation of phases, and extracting at least part of at least one of the phases with an extraction medium.  The mixture may contain by weight up to 10 per cent vanadium as V2O5, 30-60 per cent silica, and 10-50 per cent boric oxide, and have an alkali metal oxide to vanadium pentoxide ratio of 1.5:1 to 3:1.  Suitable vanadium compounds are vanadium pentoxide, vanadyl sulphate and vanadyl chloride, and suitable alkali metal compounds are oxides, carbonates, bicarbonates, sulphates, bisulphates, and nitrates: alkali metal vanadates, borates, or silicates may be used.  The glass may be formed into spheres or rods and heated at 400 DEG -700 DEG C. for 24 hours. Extraction may be carried out with caustic soda, hydrochloric, sulphuric, or nitric acid; the caustic soda solution may be buffered with potassium dihydrogen phosphate.  In examples, a mixture of vanadium pentoxide, potassium sulphate, potassium carbonate, silica, and boric oxide is fused at 1300 DEG C., broken into pieces, heated at 500 DEG C., and extracted with boiling aqueous caustic solution of boiling hydrochloric acid.  The catalyst is useful for the oxidation of sulphur dioxide to sulphur trioxide.

Title: Data handling system
IPC: G06F13/18
Filed: 1974-06-05
Abstract: 1442078 Priority network INTERNATIONAL BUSINESS MACHINES CORP 5 June 1974 [21 July 1973] 24811/74 Heading G4A A priority control arrangement for granting service requests presented on a number of request lines scans the lines in a predetermined sequence to grant service to the first activated line, any granted service causing the scan to restart at the beginning of the sequence with scanning of a previously serviced line or lines being omitted until a full scanning sequence has been completed in which no service requests were granted. Initially a "power on reset" signal sets FF44 and via line 46 resets flip-flop 10, 14; 20, 24 &c. in each of a number of stages corresponding to respective service request lines REQ1 . . . REQn. A clock generator 40 then triggers flip-flops 10, 20, 30 which are set in a fixed sequence by the output of flip-flop 44 via OR 47 and AND 16. If when each flip-flop is set no corresponding service request is present, the flip-flop output passes the associated AND 18, 28, 38 and OR 19, 29, 39 to set the next flip-flop in the sequence. If however a service request is present the corresponding AND 12, 22 sets the corresponding interlock flip-flop 14, 24 which blocks the corresponding AND gate 18, 28, 38 to terminate the scan and, via OR 49 and 47 energises AND's 16 and 17 one of which conducts to restart the scan either with the first flip-flop 10 or with the second flip-flop 20 depending on whether a service request has been detected on the first request line REQ1. The interlock flip-flops 14, 24, when set, enable their associated AND 17, 27, 37 so that the corresponding flip-flop 10, 20, 30 is by passed and a serviced request line is locked out until, in response to an output from OR 39, flip-flop 44 is set whereupon the system is reset in the same way as by the "power on reset" signal. The request lines feed service requests from peripheral processors or I/O units to a central processor.

Filed: 1920-08-30
Abstract: 172,107. Bates, A., Reid, R. G., and British United Shoe Machinery Co., Ltd. Aug. 30, 1920. Roller apparatuts ; burnishing by compression.- The edges formed at the junction of two faces of attache cases, and like leather &c. goods, are finished by operating thereon with mechanicallydriven tools the abrading or burnishing parts of which are rapidly moving in a plane inclined to the faces which join to form the edge. The apparatus used comprises a scouring-roll 1, Fig. 2, having a flexible periphery on which a sheet of abrasive paper is secured. The work is positioned in a rest 2 having a lenticular slot opposite the roll and is adjustably secured to a member 9 removably pivoted at 10 for slight movement about a vertical axis to a boss 12. The rest is reciprocated by the boss 12 engaging a screw 13 driven through a clutch 20 from either of the oppositely rotating pulleys 21, 22. The clutch is operated by a rod 16 having collars 23 and cushioning-springs 24, one of which is engaged by an arm 15 on the boss 12 at the end of each traverse. Scouring the edge at anything but a small angle is avoided owing to the speed of traverse being slow compared to the peripheral @@ eed of the roll. After the edge has been abraded it is burnished by a heated iron 30, Fig. 5, rapidly oscillated about a shaft 32 by an eccentric pin 33. Lips 35 of the iron 30 are both inclined to the plane of its oscillation and the work is positioned against an adjustable plate 36, which lies in the same plane as one of the lips 35. The iron is heated by a gas flame in the usual manner, for example as described in Specification 27762/09, [Class 17 (i), Boots and shoes, Apparatus for making &c.]. According to the Provisional Specification, the finishing operations may be applied to harness, boots, &c.
