Title: Improved method and device for analysing test gases
IPC: G01N7/08
Filed: 1924-05-20
Abstract: 216,861. Mono Ges. May 31, 1923, [Convention date]. Gas analysis.-In gas-analysis apparatus having a combustion chamber which contains an oxygen carrier and through which the gas to be analyzed is passed, means are provided for supplying a current of oxygen-containing gas to the combustion chamber between each passage of the gas to be tested in order to revivify the oxygen carrier. In one construction oxygen or air is drawn into a vessel 5, Fig. 1, at the same time as the gas to be tested is drawn into a receiving vessel 2 the conduit 1 communicating with a rising and falling liquid level. On the return of the actuating liquid, oxygen is forced from the vessel 5 through a combustion chamber 8, which contains an oxygen-carrier such as copper oxide, but the gas to be tested is not forced through the combustion chamber until a branch 9 has been sealed. In a modification, the vessel 5 is replaced by a tube 10, Fig. 2, having branches 11, 12 which in turn have branches 13, 14 respectively; the branch 13 communicates with a source of air or oxygen and the branch 14 is connected to an aspirator. When the actuating-liquid falls so as to uncover the junctions 15, air or oxygen is drawn by the aspirator along the path 13, 16, 17 18, and 14, thus passing through the combustion chamber 20. At the same time the sample of gas to be tested is drawn into the measuring vessel. The Specification, as open to inspection under Sect. 91 (3) (a) describes also a further modification in which the carbon-dioxide content of the gas, for example producer gas, is determined at the same time as the oxygen carrier is revivified, after which, by the manipulation of vessels containing mercury, the supply of air is cut off and a further sample of gas forced through the combustion chamber. The gas after treatment in the combustion chamber may be passed directly to a measuring bell, if the hydrogen content is to be determined, or through an absorption vessel for the estimation of the total carbonic-acid content. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to burners for liquid combustibles
IPC: F23D11/14
Filed: 1921-04-29
Abstract: 168,853. Gemayel, J. Sept. 10, 1920, [Convention date]. Air and steam pressure sprayers.-A liquid-fuel spray burner for projecting the atomized combustible in the form of a flat sheet consists of a casing divided into two shallow superposed compartments 1, 2 having fuel and steam or air connections 8, 9 respectively and separated by a partition 3. The partition 3 is provided with a recess 4 forming a reservoir below the oil fuel connection 8 and is formed with ridges and grooves 5 over its remaining upper surface. The lips 6, 7 of the compartments 1, 2 are also formed with ridges and grooves corresponding to the grooves and ridges in the partition 3. A removable plate is secured over an opening 10 at the rear of the compartment 1 to facilitate cleaning. The Specification as open to inspection under Sect. 91 (3) (a) comprises an arrangement of the burner shown in Fig. 6 (Cancelled), in which a pipe 12 connects the steam or air pipe 9 to the fuel pipe 8 to allow steam or air to be admitted to the compartment 1 for cleaning. The pipes 8, 9, 12 are fitted with control valves 15. This subject-matter does not appear in the Specification as accepted.

Abstract: 911,565. Lubricators &c. DAIMLERBENZ A.G. April 7, 1961 [April 12, 1960], No. 12643/61.. Class 12 (3). A lubricating system incorporated in the rotor bearing arrangement of an axial fluid-flow machine comprises a unit E between each pair of independently rotating rotors, with a lubricant distributing disc or element 17 positioned inside the web 14<SP>1</SP> of the blade carrier 14. A main tube 26, for blocking air, fixed to the element 17 encloses tubes 27 and 28 for the feed and return of lubricant respectively. Lubricating oil Fo is fed under pressure through tube 27 into radial bore 29 in the element 17, thence through bores 30 into bearings 24 and 25. From the bearings, return oil Ro collects in annular chambers 31 and flows both through ducts 37, which connect with annular collecting passage 36, and through bores 32 and 33 to the return tube 28. The blocking air S in the tube 26 also passes into the element 17 via a number of radial bores 34 in the latter and further distributing bores 35 to points on the inner side of labyrinth seals 22 and 23 to where the air pressure exceeding the oil pressure prevents a loss of lubricant. A small amount of blocking air penetrates past the seals and combines with the return oil which is subsequently de-aerated.

Abstract: 1361488 Mechanical switches; waveguide switches DECCA Ltd 14 July 1972 [4 May 1971] 12979/71 Headings H1N and H1W A multi-port coaxial switch for coupling microwave power between a first port 3 and any one of a set of several ports 40, 40a, 40b, 40c, comprises a rotor 13 adapted to constitute a section of coaxial transmission line and permanently connected to input port 3. The inner conductor of input port 3 consists of parts 8, 9 and 11 connected by spring fingers 11a to the inner conductor 19 of rotor 13 consisting of parts 20, 21, 24, 26, 31 and 30 connected by spring fingers 50 to the inner conductor 51, 47, 46 of output port 40. The outer conductor of input port 3 consists of a part 6 connected by a spring ring 17 (or by spring fingers 17b, Fig. 4 (not shown)) to the outer conductor of rotor 13 consisting of extension 16 on rotor 13 which is right-angled and has parts 37, 34 and 29 connected by spring fingers 44 to the outer conductor 41 of output port 40. The upper part of rotor 13 namely outer parts 29, 34 and inner parts 30, 31 are mounted telescopically in the lower part of rotor 13 so that they can be withdrawn from output port 40 to break contact at spring fingers 44 fixed to port 40 and spring fingers 50 fixed to rotor 13. Rotor 13 is supported in bearings 15 and 55. Attached to cover 2 of the switch is a fixed plate 58 having on its periphery four detent slots 59, Fig. 2 (not shown). The operation of the switch is as follows. Turning handle 60 rotates a drive plate 66 which has a cam surface which forces a pin 68 out of its slot 59 to pull down a stirrup (see Fig. 3) which pulls the upper part of rotor 13 out of output port 40, and rotates rotor 13 until its end is adjacent the desired output port when pin 68 slides into the appropriate slot 59 and the telescopic end of rotor 13 is forced into the output port by compression spring 35. Microswitches around the inside of the periphery of the switch are actuated by cam surfaces on drive plate 66 and the rotor top plate 71 to indicate the position of the rotor 13.
