Title: Improvements in and in Apparatus for the Separation of Nitrogen and Oxygen from Atmospheric Air.
Inventor: PICTET RAOUL PIERRE
Filed: 1904-06-27
Granted: 1904-11-17
Abstract: 14,431. Pictet, R. P. June 27, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Nitrogen; oxygen.-Nitrogen and oxygen are obtained by liquefying air and fractionally evaporating it. The gases so obtained are used to cool the air to be liquefied, and the liquid air or oxygen is evaporated by means of a regulated supply of air. The apparatus shown comprises a chamber 1 preferably rectangular, and divided into compartments 3, 4 from which nitrogen and oxygen are collected respectively through outlet pipes 32, 33. The compartment 3 is preferably about twice as large as the compartment 4. Air, previously compressed and cooled by suitable means, is fed into pipes 5, 24 communicating respectively with pipes 7, 25 through two series of parallel worms 6, 22, arranged respectively in the compartments 3, 4. The pipes 7, 25 communicate respectively by pipes 8, 26 with two series of flat spirals 10, 27, arranged as shown at the bottoms of the compartments 3, 4, and communicating through pipes 12, 28 with filters 13, 29 adapted to remove solid carbon dioxide. The filters 13, 29, as shown separately in Figs. 2 and 4, each comprise two parts connected by valved and forked pipes 35, 37 to the supply and exit pipes, so that either part can be cut out when desired. Each part comprises an outer casing 32 provided with a screw cap 33 and an inner perforated cylinder 34 surrounded by a sheath of cotton fabric. The inner cylinders fit into grooves in the ends of the casings. The spirals 10 are enclosed by spiral plates 11. Pipes 14, 30 provided with stop-cocks 16, 31 respectively conduct liquid air from the filters 13, 29 and deliver it into the compartment 3, above a series of horizontal plates 17 constructed suitably so that the evaporated nitrogen has to pass through thin layers of liquid air. The plates 17 have openings provided with upturned lips and caps, or they may consist of trellises or latticework, the lower layers having the finer meshes. Overflow, pipes 18 connect the upper plates to cups formed in the lower plates, and a pipe 20 conducts liquid to the centre of the spiral plate 11. The outer side of this plate is connected by a pipe 21 to the bottom of the compartment 4. In starting the apparatus, a quantity of liquid air is placed in the compartment 3. Compressed and cooled air is then fed into the pipes 5, 24, the supply being regulated by the cocks 16, 31. The air becomes liquefied in its passage down the apparatus, and evaporates some of the liquid in the chamber 3, before reaching the plates 17. The nitrogen evaporated in the chamber 3 is freed from oxygen in its passage through the plates 17, so that the liquid fed to the compartment 4 is rich in oxygen. This liquid is evaporated by the coils 27 and escapes at 33. The purity of the products is determined by the amounts of air fed into the pipes 5, 24.

Granted: 1905-06-22
Abstract: 15,122. Geyer, H. J. W. July 6. Leaf-turners.-Relates to a device for turning the leaves of music or books. A spindle 19 is mounted in a framework attached to the support 1, and carries a spring-controlled pulley 29, and arms 24, 27 and 40, the whole being secured by a nut 38 screwing on the exterior of an extension 34 of the pulley 29. A cord 49 passes around the pulley and leads to a treadle 51. The outer ends of the arms 24, 27 are brazed to the surface of a tube 26 slotted at 41 for the movement of the link 42. The link 42 is pivoted at one end to the arm 40 and at the other to a square rod 45, which has a detent 63 working in a slot on the underside of the tube 46 adjustable in the tube 26. The tube 46 has rigidly secured to it a finger 52 provided with a rubber block 53, and the rod 45 carries a movable finger 54 with a rubber block 58. In operation, the book is placed somewhat to the right of the apparatus, and the fingers 52, 54 are adjusted according to the width of the leaf. On depressing the treadle 51, the finger 54 is drawn to the finger 52, the leaf being caught and held by the rubber blocks 53, 58. An offset 64 engages with a projection 62 on a bracket 61, and draws down a latch 36 from engagement with a notch 9 in the tongue 4, and a further pull on the cord swings the tube 26 round, and with it the leaf, until the latch 36 comes against a lug 8 on the tongue 5. During this motion, the leaf is pulled out from between the blocks 53, 58. On releasing the treadle, the arrangement assumes its original position.

Title: Improvements connected with Roller Blinds or Curtains
Inventor: WAGELEY ROBERT ELLIOTT
Filed: 1904-09-13
Granted: 1904-10-13
Abstract: 19,724. Wageley, R. E. Sept. 13. Window blinds.-Relates to means, particularly applicable to spring-actuated roller blinds of the type known as " Hartshorn " blinds, for preventing the blind from being drawn down too far, and consequently being detached from the roller or torn. The end of the roller is provided with a channelled plate 3, furnished with a bridge 4 carrying the pin or stud 5. A stop 7, having an outwardly-projecting stud 9, slides in the channel or way in the plate 3, the motion being limited by a projection 8 thereon engaging a shoulder 6 on the plate 3. When the blind 2 is wound up, the arm 13 of the stop 7 lies against the surface of the roller beneath several convolutions of the blind. On lowering the blind and releasing the arm 13, the stop 7 falls into the position shown in Fig. 3, where the stud 9 engages a projection 10 on the bracket 11 and prevents further unwinding of the blind. The device is so arranged that, when the stop 7 comes into action, the winding-spring returns the roller half a revolution before the operation of the catch, at the opposite end of the roller, which secures the blind, in order to allow the blind to be drawn slightly to release the catch when the blind is to be wound up. The lower face of the stud 9 and the upper face of the projection 10 are bevelled, to prevent the arrest of the blind in its ascent in the event of the stop 7 not being forced in during the first revolution of the roller.

Patent GB-190515968-A (GB)
Title: Improvements in Elastic Fluid Turbines.
Inventor: WESTINGHOUSE GEORGE
Filed: 1905-08-04
Granted: 1906-01-11
Abstract: 15,968. Westinghouse, G. Aug. 6, 1904, [date applied for under Patents Act, 1901]. Elastic-fluid turbines.-The blades of a parallelflow turbine are in three sets, the blades of each set being of a different form, as shown in Fig. 13. Motive fluid leaving the nozzles 42 acts first upon two rings of rotating blades 43, co-operating with fixed blades 44. The second set 45, 46 consists of stationary blades 45, designed to convert pressure into velocity, alternating with moving blades 46 between which the pressure is practically constant. The third set 47, 48 consists of fixed and moving blades of the Parsons' type. A turbine using blades of this nature is shown in part section in Fig. 1, and is composed of two precisely-similar turbines with their inlet ends placed together. Motive fluid enters the wheel through nozzles in a block 49 and travels to the left towards an exhaust port 22, and at the same time to the right towards a similar exhaust (not shown). When the turbine exhausts into a vacuum, a liquid seal 23 is provided at the joint between the framing and the bed-plate, which excludes air from the exbaust pipe, but does not prevent relative expansion. Each half of the whole drum, to the left or right of the central web, carries a complete set of blades as shown in Fig. 13. The nozzles are divided into two sets, one set being used for normal working, and the extra set being brought into action by a governor upon a certain increase of load. Fig. 3 shows the nozzles arranged in three groups 42, the normal-load nozzles being supplied by ports 26, and the overload nozzles by ports 27. Each group of nozzles is formed in a segmental block 49, a developed view of which is shown in Fig. 6 and a section in Fig. 1. The ports 26, 27 are supplied with steam by passages 24, 25, Fig. 3, respectively, the wall dividing these passages being so arranged that all the ports 26, 27 are in a line round the casing. Lift valves, of which the seats only are shown in Fig. 3, control the admission of steam to the passages 24, 25.

Title: Improved Process of and Apparatus for the Treatment of Sulphide Ores.
Inventor: BAKER HARRY
Filed: 1905-10-31
Granted: 1906-10-25
Abstract: 22,235. Baker, H., and Smith, A. T. Oct. 31, Sulphur.-Complex sulphide ores containing zinc, lead, copper, &c. are agitated in a finely-divided state with a higher chloride of a metal such as iron or copper, whereby the lower chloride of this metal and chlorides of the metals present in the ore are obtained, with liberation of sulphur ; the lower chloride, say ferrous chloride, is then submitted to the action of chlorine gas, giving the higher chloride, which is again caused to act upon the ore. Fig. 1 shows a form of apparatus suitable for carrying out the process. The stone tank A is charged with warm water through the opening E, and the stirrer D, the shaft C of which is adjustable, is lowered to near the bottom of the tank and is started running ; the finely-powdered ore is then introduced. The centrifugal pump T is started and the valve S and a valve in the chlorine-supply pipe H are opened; the liquid is thus pumped through the absorbing-tower G, where the ferrous chloride takes up the chlorine and is reconverted into ferric chloride. The re-opened ferric chloride runs back through the pipe K below the surface of the liquid in the tank A, while waste gases escape through the pipe L. Ore may be added continuously or at intervals, and as the action slackens the flow of chlorine is decreased and finally stopped, the agitation being however continued until the action has ceased. The liberated sulphur accumulates as a scum on the surface of the liquid, and may be removed by hand or automatically through the man-hole M, or be sucked off &c., after which it is fitered in a press, the liquid returned to the tank, and the sulphur cakes further treated in known ways. The liquid may be heated by injection of steam or cooled by blowing in air, as required. In another form of apparatus, the tank is of conical form and the pipe supptying the chlorinated liquor extends nearly to the bottom of the tank, thereby agitating the contents ; in a third modification, the tank is of cylindrical shape and revolves on an horizontal axis; materials are charged in at one end and are discharged from a funnel-shaped opening at the other end into a smaller tank, from which it is pumped to the chlorinating tower and so back to the main tank. The slurry of chlorides is then treated with metallic iron or zinc to precipitate the lead, copper, &c., while zinc, i:on, &c. remain in solution. A further amount of sulphur separates out during this part of the process and is removed and treated as before described. Chlorine.-The zinc chloride solution obtained as described above is purified, evaporated, and fused ; the fused chloride may be electrolyzed yielding metallic zinc, and gaseous chlorine for re-use.

Title: New or Improved Means for Operating the Contact Lever which Produces the Break Spark in Magneto Ignition Apparatus.
Inventor: WHITE ALBERT FRANCIS
Filed: 1906-01-15
Granted: 1906-05-31
Abstract: 1091. White, A. F. Jan. 15. Gas and like engines, igniting in. In a magnetoignition system, the spark lever is operated from an arm on the armature shaft or other moving part through a flexible connexion such as a series of metal pieces in a tube, or a wire, a quick break *being given. The roller c on the half-time shaft d oscillates the armature of the magneto a by striking the arm b. The arm b is connected to the lever e by pieces h of metal or other hard material contained in the tube g. When the arm b oscillates the armature, it strikes one of the pieces h and so moves the lever e from the contact f, causing a spark to pass. In a modification, a tubular passage containing the metal pieces is only used to transmit motion round a curve. In a further modification, a flexible wire w in a guide-tube g is attached to the levers b, e as shown in Fig. 3. Instead of the arm b, an arm driven from a suitably-timed engine shaft may be employed.

Abstract: 11,022. Roger, R. May 11. Winches, windlasses, and crabs.-A winch such as is used for unloading ships and the like is provided with an attachment, comprising a compound drum mounted on an auxiliary shaft, for more rapidly lifting and lowering light loads. Fig. 2 shows one form of the invention in side elevation. On one of the side frames B<1> of the winch is mounted a supplementary framing A<1> connected by a diagonal strut C to the opposite side B<2> of the winch, which strut is continued beyond the frame A' and forms a bearing for the double drum E', F<1>. When light loads are being lifted, the lifting-rope G<1> is passed round the large drum E', and the smaller drum F<1> is driven from the whipping-end B<3> by means of the rope H<1>. The ropes G<1>, H<1> are secured to their respective pulleys E', F<1> by being passed through holes therein. Two sets of supplementary pulleys may be mounted on opposite sides of the winch. If. desired, the framing supporting the supplementary pulleys E', F<1> may be independent of the winch frame and may be bolted to an horizontal or a vertical support, such as the coaming of a hatchway. The driving- rope H<1> is, in this case, led round suitable guidepulleys to the pulley F<1>. The speed ratio of lifting can be varied by making the compound pulley E<1>, F<1> with several steps, or by detaching the pulley E<1> and substituting one of different diameter.
