Title: Improvements in apparatus for delivering mists or aerosols for breathing purposes
IPC: A61M11/00
Filed: 1949-10-26
Abstract: 675,524. Mist producers. VERGNE, P. L. A. Oct. 26, 1949 [Jan. 31, 1949], No. 27504/49. Class 81 (ii). In a mist producer used for medical purposes in which a liquid is atomized in a gas means are provided for stopping the operation of the atomizer whenever the patient is not inhaling. As shown, liquid in reservoir 2 is atomized by a stream of compressed air from the jet nozzle 5 passing over the nozzle 4 of the tube 3. Com-, position of the aerosols obtained is varied by knob adjusted deflector 7. Additional air may be supplied to the apparatus through the valve 10. Control of the compressed air to the jet 5 is by a diaphragm operated valve 19. The diaphragm 12 is located at one side of the producer casing such that it divides a space within the casing into two parts-part 14 open to the atmosphere and part 16 in communication via the conduit 17 with the tube 9 which leads to the patient's face mask &c. Whenever the patient is inhaling suction is created in 16 and on the diaphragm moving inwardly the lever 18 depresses the valve 19 thus allowing compressed air to flow via inlet 20 and passage 21 to a chamber 28 formed in the atomizer supporting block. This block is removable. The jet nozzle 5 is connected to chamber 28 via tube 6. The atomizing process may also, or alternatively, be controlled by regulation of the flow of the atomizing liquid to the nozzle 4. Provision such as push button means 13a is provided for operating the valve 19 when the suctional effect of the patient's inhalation is not sufficient to cause inward movement of the diaphragm.

Title: Improvements in and relating to the vulcanization of tire casings
IPC: B29D30/06
Filed: 1920-09-28
Abstract: 162,263. Fisk Rubber Co., (Assignees of Midgley, T., and Naylor, R. B.). April 19, 1920, [Convention date]. Moulding india-rubber tyres.-Tyre covers are subjected to a preliminary partial vulcanization by the application of heat to the interior, to avoid displacement of the fabric &c. of the body during subsequent operations, and also to unite the body and tread, but to leave the surface of the tread in a state capable of being moulded. The covers are then pressed in moulds to form non-skid patterns &c. and the vulcanization is completed. A cover 10, Fig. 4, is built or mounted on a hollow core 13, and may be bound by the usual wrappings, or preferably surrounded by an asbestos blanket 16 in which are inserted springs to exert pressure on the tyre in a direction away from the crown. Steam is passed through the core 13 until the body is vulcanized but the tread remains plastic. The blanket 16 is removed, and the tyre is placed in a mould to form the tread pattern, and vulcanized under pressure as usual. In a modification, the covers are placed in the moulds at the beginning of the operation, the moulds being held open during the preliminary vulcanization. Into a chamber 35, Fig. 9, with cover 40 held by lugs 39 projects an hydraulic ram 41 to the table 42 of which are pivoted linked, bell-crank levers 62, 64 on which rests a block 60. On the table 42 are placed moulds 52, 53 surrounding tyres mounted on cores 51 and held apart by double wedges 56 on toggle links 57 pivoted to head 58. Steam is admitted to the cores 51 by flexible pipes 47, 48, 49, compressed air being admitted to the chamber 35 if desired to prevent " blowing." On completion of this operation the ram 41 is raised, pawls 67 on the bell-cranks 64 come into contact with projections 68 on the chamber, and the block 60 is raised against the lowest head 58, upsetting the toggle joint, and withdrawing the double wedges 56, whereupon the weight of the moulds closes them. Preferably the size of the heads 58 is such that the toggles are upset successively from the bottom to minimize shock. The moulds are pressed against the cover 40 and steam is admitted at 45 to complete the vulcanization. The invention is distinguished from those in which a tyre body is partially vulcanized, an unvulcanized tread is applied, and the vulcanization completed. Specification 130,168 is referred to.

Abstract: 976,653. Shoe drum brakes. GIRLING Ltd. July 18, 1963 [July 19, 1962], No. 27716/62. Heading F2E. Actuating means for separating the shoes 10, 11 of a drum brake comprise a pair of complementary radial levers 21, 22 of which the outer ends lie between and engage abutments 27 on the ends of the shoes and mechanical means for urging the inner ends of the levers towards each other, the levers being pivoted intermediate of their ends on or about a stationary part as at 23. The brake described is of the duo-servo type with the shoes adjustably coupled at 15 and retained on the back plate 13 by an anchor pin 17. The inner ends of the levers are bifurcated and carry trunnions 28 through both of which passes a flexible cable 29. One end of the cable 29 is anchored against a trunnion by a nipple 31 whilst the other passes through a conduit 32 to connect to the hand-brake lever, so that when a pull is applied, balanced inward forces act to move the inner ends of the levers towards each other. When both back wheel brakes are actuated by a cable and conduit, they may be carried over a pulley for automatic compensation. Operation by the levers 21 and 22 is intended for emergency braking and parking and the shoes are normally operated by an hydraulic cylinder 18 mounted on the back plate. The body of the cylinder 18 supports the pivots 23 of the levers which are retained thereon by a plate 24 which also provides anchorages for the pull-off springs 26. The cable 29 is maintained under sufficient tension to cause the levers to follow the shoes when the brake is applied hydraulically.

Abstract: 1348685 Centrifugal separation of gases N A L WIKDAHL 14 June 1971 [10 July 1970] 27845/71 Heading B2P A gas mixture is separated into component fractions according to their molecular or atomic weight by subjecting the mixture to the centrifugal force applied in a vortex having a diameter of not more than 5 mm. at a gas inlet absolute pressure of 5-1000 mm. Hg., and a pressure ratio P inlet/P outlet within the range of 1.5 to 10 and discharging a heavy fraction from the peripheral portion of the vortex and a light fraction from the core portion thereof. The gas inlet velocity may be subsonic or supersonic and the range of operating temperatures may be from -20 to 300C. A vortex separator for treating the gas mixture has a separation chamber which may be wholly conical or partly cylindrical and cone shaped only at the apex end. The cone may be straight sided or may have convexly or concavely curved sides of uniform or increasing or decreasing curvature. The diameter of the chamber is not greater than 5 mm. at the base end and is at least 0.01 mm. at the apex end and may decrease continuously or in stages towards the apex end. The length of the chamber should not be greater than 200 mm. nor less than 5 mm. The gas mixture is fed to the base end of the separation chamber through two or more uniformly spaced tangential inlets which open into an annular space defined between the wall of the chamber and a tube which is integrally formed with the base of the chamber and projects inwardly therefrom from a central outlet for the light gas component. The separator may be made of stainless steel, aluminium, nickel or chromium alloy, ceramic, glass or plastics, examples of which are given.  A number of vortex separators may be arranged in two series in cascade. In one series, the core portion from each stage is separated and combined in series with the apex portion from a later stage, and this is repeated. at each stage to the end of the series. In the other series, the apex portions are separated and sent through with the core portions from a later stage. The process may be used for separating isotopes of uranium from each other or carbon dioxide from air. It may also be used as the molecule separator stage in gas chromatography-mass spectrometry systems.
