Title: Manufacture of combustible gas
Inventor: MILNER MICHAEL JOHN
IPC: C01B3/16
Filed: 1961-11-10
Abstract: <PICT:1008206/C4-C5/1> A cyclic process for the manufacture of com bustible gas comprises passing hot gas from a gas-making phase through sealing means 14 which allows the hot gas to pass in one direction to a carbon monoxide conversion plant 17, 18 but which does not allow flow of the hot gas in the reverse direction or flow of waste gases from a plant-heating phase in either direction, the gas from the gas-making phases not being subject to substantial partial cooling in passing through the sealing means.  The sealing means may comprise an automatically controlled mechanical valve of the hot-gas type, or an hydraulic sealing device.  The conversion to carbon dioxide of the carbon monoxide in the gas from the gas-making phases may be affected by using an iron oxide catalyst only, or non-ferrous hydrogenating catalyst only, or both types of catalyst.  After preliminary heating of the gas-making plant by continuous passage of heating gases from the combustion chamber 1, through the catalyst chamber 6, and waste heat boiler 12, and preliminary heating of the conversion catalyst chamber 17 by passage of superheated steam, a cyclic operation comprising a heating-phase and steam purge, followed by a gas-making phase and a second steam purge, is commenced.  During the plant-heating phase air and heating fuel, e.g. petroleum gases, or petroleum distillate, are burnt in combustion chamber 1.  During this phase and the subsequent steam purge the stack valve 13 is open, and, because the gas pressure is insufficient to break the hydraulic seal in 14, the gases pass through outlet 10 to the steam boiler 12 and thence to stack valve 13. After a steam purge, the stack valve 13 is closed and liquefied petroleum gas feedstock and steam are introduced through the inlets 8 and 9, and are cracked in passing through the catalyst bed 7 to form a gas comprising carbon dioxide, carbon monoxide, and hydrogen. Specifications 973,152 and 1,008,205 are referred to.

Title: Lubricating compositions containing phosphonic acid salts
IPC: C10M169/00
Filed: 1958-12-16
Abstract: A lubricating oil composition comprises a neutral metal salt of a C1-C30 phosphonic acid.  The phosphonate is an anti-oxidant, imparts load-carrying and anti-wear properties to the composition and can be used to thicken the lubricating oil to form greases having high dropping points.  The phosphonate may be a salt of an alkali metal, an alkaline earth metal, magnesium or aluminium, and may be added directly to the lubricating oil or formed in situ by reaction between the phosphonic acid and a metal base in the presence of at least a portion of the lubricating oil. The lubricating oil may be a mineral or a synthetic oil, or mixtures thereof.  Synthetic oils mentioned are di(2-ethylhexyl)sebacate, glycol esters, complex esters, formals, silicones and carbonates.  The lubricating oil composition may contain additional ingredients such as metal salts of C1-C30 fatty acids, metal lactates, metal hydroxy stearates, metal alkaryl sulphonates, metal petroleum sulphonates, other thickening agents (e.g. polyethylene or carbon black), viscosity index improvers (e.g. polyisobutylene), corrosion inhibitors (e.g. sorbitan monooleate), pour depressants, detergents or dispersing agents and dyes.  In examples, lubricating greases are prepared from mineral lubricating oil and (i) cetane phosphonic acid and lithium hydroxide, (ii) dodecane phosphonic acid and calcium hydroxide, (iii) ethane phosphonic acid, cetane phosphonic acid and calcium hydroxide, (iv) ethane phosphonic acid, dodecane phosphonic acid and lithium hydroxide, (v) ethane phosphonic acid, calcium hydroxide and calcium petroleum sulphonate, (vi) cetane phosphonic acid, calcium hydroxide and calcium acetate, (vii) benzene phosphonic acid and aluminium hydroxide or (viii) sodium dodecane- or ethane-phosphonate, sodium 12-hydroxy stearate, sodium petroleum sulphonate and phenyl alpha naphthylamine.  In the case of (iii), the grease may be cut back with further mineral lubricating oil to give a fluid lubricating composition.  In the case of (viii), the effect of omitting the phosphonate or replacing it by trisodium phosphate is mentioned.  In a further example, a lubricating grease is prepared from methyl phenyl silicone oil, ethane phosphonic acid and calcium hydroxide. The grease compositions of Specification 730,875 are disclaimed.

Abstract: 1302315 Cathode-ray tubes NORTHROP CORP 31 Aug 1971 [31 Aug 1970] 40616/71 Heading H1D The passage of electrons from an extended area cathode 22 to a target 21 is controlled by coded electrodes 35-38 and one or more non- coded electrodes 30 disposed opposite each other on the surfaces of two spaced apart plate members 11 and 12. In Fig. 2 the surface of plate 12 is covered by a single earthed electrode 30, and the surface of plate 11 is covered by a plurality of electrodes forming inter-digitated pairs connected to respective bistable circuits (not shown) so that one electrode of each pair is earthed and the other at a positive potential which deflects the beam. The beam path is thus divided into 8 channels which may be controlled so that only one channel is open at a time. With electrodes 35a-38a earthed, as illustrated, only the channel 60 is open; the electrodes 38 filter the output by ensuring that there are two deflection regions in each blocked channel. The arrangement illustrated includes an accelerating electrode 44 and a modulating electrode 42 both of which preferably extend round the edges of plate 11. In a modification, Fig. 4 (not shown), electrode 30 is split into a number of transverse strips at successively increasing potentials and the mean potentials of electrodes 35-38 increase correspondingly (Fig. 5, not shown). In another modification (Fig. 6, not shown), the plate 12 is provided with grooves which define the electron channels, the bases of the grooves being coated with conductive strips which are connected together to form electrode 30. Alternatively or additionally grooves may be formed in the plate 11. The coded and non-coded electrodes may be distributed between plates 11 and 12. The plates are preferably of glass or ceramic, but plate 12 may be of conductive material.

Abstract: 1,015,198. Mandrels. ERICKSON TOOL CO. Oct. 30, 1962, No. 41055/62. Heading B3B. An expansible mandrel comprises two sets of work-gripping jaws, one set 28 of which is axially adjustable, means for expanding one set of jaws 25 and means 20 for transmitting the force to expand the other set of jaws. In operation, a workpiece is placed over the mandrel and spring-pressed plungers 38 serve to centre it. A head 14 is then moved axially by a drawbar 13 causing the collet jaws 52 to be moved axially by a draw-bar 13 causing the collet jaws 25 to be moved axially and expanded by a conical ring 24. The conical ring 24 also moves axially thus moving keys 20 engaging a sleeve 30. The sleeve 30 has a flange to engage a conical ring 29 which thus expands the other collet jaws 28. When a different length of workpiece is to be gripped, the sleeve 30 and a sleeve 32 associated therewith are rotated to disengage threads on the sleeve 30 and the keys 20 and to move the threaded portions of the sleeve opposite flats 19 on the mandrel body 18. The sleeve 30 is then adjusted axially carrying with it the collet jaws 28. The mandrel is mounted on a spindle by a flange 11. In a modification, movement of a head 44, Fig. 5, moves keys 47A to expand a collet 48. A ring 51 is consequently moved and through further keys actuates a second collet 55.
