Title: Improvements in or relating to coupling devices for use in high frequency circuits
IPC: H01P5/02
Filed: 1929-04-15
Abstract: 309,833. Marconi's Wireless Telegraph Co., Ltd., (Assignees of Hansell, C. W.). April 14, 1928, [Convention date]. Coupling oscillating and radiating circuits; thermionic amplifiers.-Relates to impedance transformers or coupling-lines of the kind in which the inductance and capacity characteristics are varied to obtain the desired transformation ratio, in a manner analogous to the exponential sound horn. In order to render the degree of coupling and transformation independent of frequency or resonance effect, the impedance of each of a number of intermediate sections is progressively increased according to an exponential or geometric law. A coupling-line 8, between a power generator 12, and a rod aerial 10, comprising single-wire or strip conductors, Fig. 1, may also be graded in impedance by utilizng the fact that the effective, inductance varies directly, and the capacity inversely as the logarithms of the spacing between the conductors. In the case of strip conductors 6, the capacity and inductance varies with the width of the strips. Fig. 2 shows an equivalent structure of wires. In Fig. 3 an intervalve impedance transformer comprises a conductor 28, surrounded by a diminishing thickness of dielectric 30, and an increasing thickness of magnetic material 32, giving a step-up impedance from left to right. The coupling element may be screened by a grounded metal tube 34. Preferably the length of the coupling element is greater than one wave-length of the frequency being handled. The Specification as open to inspection under Sect. 91 (3) (a) comprises the following subject matter :-The surge impedance of a typical low-pass filter line as shown in Fig. 1 (cancelled) is known to be equal to #L/C. If the impedance ratio for each section is N, the actual impedance is varied by progressively increasing the inductive elements or decreasing the shunt capacities from NR to N<5>R along the five sections as shown. A typical high-pass filter line may be similarly treated. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,247,592. Evaporators, multi-stage flash type; desalination of sea water. COMMISSARIAT A L'ENERGIE ATOMIQUE. 6 March, 1969 [18 March, 1968], No. 11858/69. Heading B1B. Saline solution is distilled, e.g. sea water is desalinated, in a plurality of distillationunits A, B, C, .. N each comprising a series of flash chambers 2 and associated condensers 4, and each being connected to an external heater 6; the unevaporated salt water from each unit (except the last) is mixed with make-up sea water, then passed through the heat-recovery condensers and the external heater of the following unit and introduced into the first flash chamber of said following unit. A fraction of the water evaporates in each flash chamber, and the vapours condense in contact with the tubes of the associated condenser, the condensate (i.e. desalinated water) being collected in troughs 8. The sea water to be distilled, which may be acidified or treated -with a scale inhibitor, first passes through the condenser tubes of unit A, and is then further heated in the uppermost heater 6 before being introduced into the first flash chamber of unit A. The salt water leaving the last flash chamber of unit A is mixed with make-up sea water which - has passed through the condenser tubes of the heatrejection stage n' of unit B. The mixture flows through the condenser tubes of the heat-recovery stages n of unit B, flows through the heater 6 associated with this unit, and is then introduced into the first flash chamber of the unit. The salt water leaving unit B is mixed with preheated make-up water and introduced into unit C, and so on for the succeeding units. Concentrated brine leaving the last flash of unit N is discharged from the system. The heaters 6 of the successive units can be heated by circulating the hot gas of a gas turbine successively within the heaters of the different units, the rate of flow of gas being regulated so as to ensure the necessary temperature difference within the heaters of the successive units. Similarly, the heaters of the successive units can be placed in the gas circuit between the different compression stages of the gas-turbine cycle. The gas turbine may be part of a plant for the production of electricity. Alternatively, the heaters may be heated by steam withdrawn at different pressure from a steam turbine. The temperature of each distillation-unit is maintained at the maximum value which is compatible with the limit of solubility of calcium sulphate in the sea water in the unit; although it is necessary to reduce the heating temperature of the feed solution from one unit to the next.

Title: The manufacture of ortho-hydroxyindolecarboxylic acids of the benzene and naphthalene series
IPC: C07D209/08
Filed: 1931-04-22
Abstract: o-Hydroxyindolecarboxylic acids of the benzene and naphthalene series are manufactured by the action of carbon dioxide on an alkali metal salt of a hydroxyindole or on a hydroxyindole in the presence of an alkali hydroxide or carbonate.  The process is carried out under pressure and heating.  The products are intermediates for the manufacture of dyestuffs.  The starting materials may be obtained from the sulphonic acids of indoles or naphthindoles by alkali fusion.  In an example, 6-hydroxy-2 : 3-diphenylindole is converted into its potassium salt which is treated with carbon dioxide in the presence of potassium carbonate at 220 DEG  C. and 60 atmospheres pressure to produce 6 - hydroxy - 2 : 3 - diphenylindole - 5 - carboxylic acid.  By similar treatment, 8-hydroxy-2-phenyl- and 8-hydroxy-2 : 3-dimethyl-a -naphthindoles are converted into their respective 7-carboxylic acids.  Specifications 354,392 and 385,620 are referred to.

Title: Apparatus for abrading edges of glass heets
IPC: G04C3/04
Filed: 1971-04-29
Abstract: 1312582 Grinding LIBBEY-OWENS-FORD CO 29 April 1971 [4 May 1970] 12177/71 Heading B3D [Also in Division B8] Apparatus for edge treating glass sheets S comprises means 300, 301 for moving the sheets along a defined path, a tool 435 having a abrasive surface mounted for movement toward and away from the path, means 426 for moving the tool, and monitoring means operable when a sheet reaches a predetermined position in the path to move the tool under pressure toward the path and to reduce the pressure when the tool is in working engagement with an edge of the sheet. As described, the apparatus has three tools for operating on the upper corner of the edge, lower corner of the edge, and vertical surface between the corners, respectively. The means for moving the sheets along the path consist of upper and lower pairs of roller chains 301, 302, the links of which are provided with rubber blocks, 304, Fig. 9, between which the sheets are gripped as they are received from a conveyer 389 and passed over a roller on a driven shaft 391. After treating, the sheets pass over a roller on a driven shaft 396 to a conveyer 389<SP>1</SP>. The chains are driven from a single input 327. Each tool is substantially the same and consists of an abrasive belt 435 driven by a motor 426 and supported by a member 415. The members are carried by brackets from carriages 401 movable transversely to the path of the sheets by piston- and-cylinder devices 410. The brackets are angularly adjustable on the carriages and hold the members so that the belts 435 of the tools 40a, 40b, 40c engage the upper corner, lower comer and vertical surface, respectively, of the edge of the sheets. Each device 410 is associated with a respective roller 500 for engaging the edge of the sheet and normally is pressurized to urge the abrasive belts away from the path of the sheets. When a sheet is fed along the path it engages the arm 507 of a switch 505 which actuates its associated device 410 to advance its carriage and abrasive belt at a rapid speed towards the edge of the sheet until the roller 500 carried by the carriage engages the edge of the sheet and actuates a valve to reduce the pressure supplied to the device 410. As the roller 500 follows the contour of the edge of the glass sheet, the device is actuated to maintain its belt in contact with the edge at a constant pressure. Each abrasive belt is controlled in a similar manner to grind the upper and lower corners and the vertical face of the edge.
