Filed: 1944-11-14
Abstract: 592,183. Change - speed chain - gearing. LETOURNEUR, A. A. Nov. 14, 1944, No. 22456. Convention date, June 12. [Class 80(ii)] In chain-shifting changespeed gearing, a sleeve 23. carrying a jockey-sprocket 47, which is moved axially on a fixed sleeve 20 to shift a cycle-chain 49 on to a selected one of a group of differentsized driven sprockets 16-18. is at the same time, by means of a pin 26 and helical slots 31, given a turning movement which, acting through a short cable 38, adjusts an abutment 36 for a chain-tensioning spring 37, so that the chain-tension is kept constant on all sprockets. The pin 26 forms the terminus of a single spring-returned Bowden control 56, operated by a hand-lever 59, which has an additional position 63 for moving the chain on to a fixed support 64 on the cycleframe to facilitate wheel removal. The controlled tension - spring abutment 36 telescopes in a tube 35, carried by a tension-roller arm 34, which pivots freely on the sleeve 23, and the tension-control cable 38 is passed round and attached to a grooved part 24 of the sleeve 23, so that, as the tension-roller arm 34 swings clockwise to take up the additional chain-slack on the smaller sprockets, the turning movement imparted to the jockey-sprocket sleeve .23 by the helical slots 31 and Bowden control 56, winds up the tensioncable 38 to maintain or, if desired, to increase chain-tension. An abutment 42 on the tension-cable 38 prevents collapse of the tension-roller arm 34 when the chain is moved on to the idle support 64.

Title: Improvements in or relating to gasification of fuels
IPC: C10J3/46
Filed: 1953-08-17
Abstract: 744,702. Gasifying solid and liquid carbonaceous fuels; gaseous mixtures. KOPPERS CO., Inc. Aug. 17, 1953 [Oct. 23, 1952], No. 22623/53. Classes 55 (1) and 55 (2). Fuel or synthesis gases are obtained by gasifying finely-divided solid or liquid carbonaceous fuel in one or more gasifiers 40, Fig. 1, and passing the resulting products containing unreacted fuel upwardly into a downwardly moving bed 45 of coke or other tar-free carbonaceous fuel in a producer 44, the finely divided fuel being injected axially into the gasifier 40 as a suspension in a free oxygen containing gas and surrounded by an annular stream of a chemically combined oxygen-containing gas simultaneously introduced into the gasifiers and the particles of the bed of tar-free carbonaceous fuel have no relative movement but move as a whole. The free oxygen containing gas is preferably oxygen or oxygen-enriched air and the chemically combined oxygen-containing gas may be carbon di-oxide or steam. Pressures of up to 40 atmospheres may be employed and the temperature in the gasifiers 40 may be 3,050‹ F. and in the producer 44 at the point of entry of the gases from the gasifiers 40 between 2,200‹ F.-2,700‹ F. Tar-free carbonaceous fuel is fed in from a hopper 46 and the rate of flow of the tar-free fuel in the producer may be controlled so that either all the carbon in the fuel is gasified or only a part thereof and the resulting solid residue may be used commercially as a fuel. Liquid slag and possibly iron may be withdrawn at points 48 and 49 respectively, auxiliary oxygen being added at 50 if necessary to increase the temperature. Additional steam or other gasifying agent may be introduced directly into the bed 45. The duct gasifiers 40 comprise a gasification chamber 1, Fig. 2, having fuel-oxygen suspension inlet nozzles 3 supplied with the suspension from a pipe 14. The nozzles 3 are surrounded by an annular nozzle 4 through which, e.g. steam is introduced from a conduit 11. The nozzle 4 is cooled by water jackets 5 and 6, the jacket 5 also cooling the nozzles 3. In a modification the annular nozzle for the introduction of steam is shaped like a venturi and the nozzles for the introduction of the fuel-oxygen suspension project into the gasification chamber beyond the steam nozzle. In an example gasifying high volatile bituminous coal in the dust gasifiers and using coke in the producer 44 a gas containing CO 2  4.1 per cent; CO 56.1 per cent; H, 37.4 per cent; CH 4  0.2 per cent; H 2 S 0.4 per cent; and N 2  1.8 per cent was obtained. Specifications 713,004 and 661,148 are referred to. Reference has been directed by the Comptroller to Specification 713,004, [Group XII.

IPC: E05B63/24
Filed: 1924-09-25
Abstract: 244,835. Ramsey, A. Sept. 25, 1924. Locks, cases for; bolts; lock mechanism, slider-type; spring mechanism; latches, preventing operation of; sliding bolts.-A lock with a sliding bolt is operated from the inside by turning a handle, and from the outside by turning a handle with one hand after inserting, turning and holding a key with the other. The inside and outside handles are mounted on separate spindles each having a follower which engages a lug on a blocking tumbler pivoted on the spindle of the outer handle and turns the tumbler through about 120‹ so that, engaging a finger in the tail of the bolt, it retracts it against its spring. The spindle of the outer handle is flattened and can be locked against rotation by key operated sliders acted on by a common spring. The bolt can engage the striking box when shot by separating a pair of spring-pressed hook-shaped catches. The bolt 4 has a tail 5 sliding in a casing 1 and projections 18 on a tumbler 17 pivoted an the outer handle spindle 11, engage lateral projections 19 on the tail 5 when the tumbler is blocking the shoulder 10<1> of the belt. The bolt is pressed outwards by a hooped spiral spring 6 attached to pins on the bolt and casing, and has an anti-friction roller 9 guiding it along the bottom 10 of the casing. The outer handle spindle 11 is flattened as at 20, Fig. 6, so that sliders 22 normally prevent its rotation. Retraction of the sliders against their common spring 24 by a key removes their shoulders 21 from the flat. 20 on the spindle which can then be turned to cause its follower 15 to engage the lug 16 on the tumbler 17 and turn this over. The tumbler is then disengaged from the shoulders 19, 19<1> of the bolt and engages the finger 35 thereon and retracts it as shown in Fig. 7. The key can only be used from the out side and the sliders are contained in a box 14 fixed to the outside of the casing. A boss 37 on the box 14 forms a bearing for the spindle 36 of the inside handle 38. This spindle carries a follower 39, Fig. 4, which engages a lug 40 on the tumbler 17 and retracts the boit in the same manner as the follower of the outside handle 8. For further security, a pin 26 can be advanced into a hole 27 in the tumbler, from the inside of the door. The casing has a flange and lip 3 extending round the door 2 to prevent forcing by a jemmy.

Title: An improved process and apparatus for the manufacture of alcohol or ether
IPC: C07C29/06
Filed: 1919-09-16
Abstract: 152,495. Damiens, A. A. L. J., Loisy, M. C. J. E. de, and Piette, O. J. G. Sept. 16, 1919. Alcohol or ether is produced by absorbing ethylene is sulphuric acid in the presence of a catalyst, and then distilling the resulting sulphovinic acid with water. The catalysts mentioned are the sulphates of iron, cobalt, nickel, cerium, manganese, chromium, molybdenum, tungsten, uranium, copper, lead, mercury, gold, vanadium, titanium, and tin, as well as phosphoric, phosphorous, sulphuric and arsenious anhydrides. Industrial gases containing ethylene, e.g. illuminating gas or coke oven gas, may be employed, in which case they are subjected to preliminary purification for the removal of ammonia, benzol &c. The temperature cf absorption is preferably fixed at 100-120‹ C. The ethylenic gases are first dehydrated by traversing columns d in which they meet a circulating stream of sulphuric acid containing the catalyst which has been saturated with ethylene in later columns. The gases then pass to the columns a, where the ethylene is absorbed by fresh sulphuric acid mixed with catalyst. Each column is provided with a pump g for maintaining a continuous countercurrent circulation of acid, and the acid is preferably broken up into spray inside the columns. The acid from column a may be withdrawn for dilution and distillation, the acid remaining after distillation being then concentrated by waste heat from the furnaces; or it may be passed backwards from column to column until it reaches the required dilution in column d, when it is filtered in the press j and distilled in the apparatus k, the acid remaining being transferred if desired to the ammonia absorption tower. The production of alcohol or of ether from the distillation process depends upon the degree of dilution of the sulphovinic acid.

The frame is locked in closed position by a toggle mechanism operated by link 16. Vulcanisable material is used to form the sole, the last, L, and/or the mould being heated. The tilted attitude of the mould, shown in Fig. 1, facilitates the movement of the last to and from the mould. The mould shown in closed and open positions in Figs. 6 and 7 comprises a base plate 25 to which mould sections 26 are pivoted about vertical pin 29, and portions 27 pivoted to sections 26 about horizontal pins 28. The shoe may also be formed by first attaching a pre-formed sole extension 35 to the upper, and then moulding on the sole which becomes integral with the lower portion of the extension, see Fig. 8. The frame 34 of this mould may be in one or more pieces. The sections of the various moulds may be slidably mounted instead of pivotally mounted as shown. The moulding operation may be effected by pressure moulding, non- pressure moulding, or extrusion moulding. The sole may be formed from rubber, plastic, e.g. polyvinylchloride, polyethylene, or polystyrene, or leather rendered mouldable in a heated mould by wetting. The tread layer may be more resistant than the remainder, e.g. the sole may comprise a solid rubber tread, a solid rubber or sponge rubber compound middle sole, and a felt filler covering a zone of the middle sole inset from the edge thereof, the margin of the middle sole being bonded directly to the upper. Alternatively, the sole may comprise a thin leather tread and sponge rubber middle sole, or a thick leather outsole and thin rubber middle sole. The soles may also be formed of a single material, e.g. vulcanisable rubber-based or plastic-based compound, or crude or semi-cured rubber-based or plasticbased compound in one piece or in two or more pieces which may be joined together, e.g. by cementing or sewing, before being placed in the mould.
