Title: Process for the manufacture of particle board or fibre board by incorporation of a binder in gaseous form
Inventor: VERBESTEL JEAN-BAPTISTE
IPC: C08L91/08
Filed: 1969-03-06
Abstract: 1,262,313. Fluidised bed apparatus. J.-B. VERBESTEL. 6 March, 1969 [19 March, 1968], No. 11937/69. Heading B1F. [Also in Division C3] An apparatus for carrying out the impregnation of lignocellulosic material with gaseous material capable of forming a polymeric binder for the lignocellulosic material comprises three concentric cylinders 30, 31, 32. 30 contains a fluidised bed 4 having a base 3 consisting of several screens which assure a homogeneous distribution of a carrier gas and gaseous binder ingredients and in the centre of the bed is an agitating arm through the hollow centre of which the lignocellulosic material may be introduced. 31 surrounds 30 and ducts the flow of the carrier gas and lignocellulosic material downwards to facilitate the separation of the material from the gas, whilst 32 functions as an expansion chamber in which the separation of the material from the carrier gas is completed and the carrier gas is recovered. The lignocellulbsic material is discharged through an air lock 11 at the base of 32. The gaseous material may be introduced to the fluidised bed by means of a dosing system. The gaseous materials are produced in evaporation systems 15, 16 and 17 and introduced into the stream of carrier gas passing along pipe 2 by valves 12, 13 and 14. The rate of evaporation of the materials is determined by regulating the temperature of the evaporating systems by means of automatic temperature level controls 24, 25 and 26.

Title: Improvements in or relating to reflecting condensers for dark field illumination
IPC: G02B21/10
Filed: 1924-05-16
Abstract: 221,764. Leitz, E. [Firm of]. Jan. 17, 1924, [Convention date]. Microscope condensers.- To enable the full aperture of a microscope objective to be employed when using dark ground illumination the reflecting condenser is arranged so that a delimitation of the light rays is effective in the surface conjugated to the aperture stop of the objective, such delimitation being effected optically. A reflecting condenser 5 receiving light through the lenses 6, 7, has two curved surfaces 8, 9 which reflect the light rays and between which lies a real image of the plane containing the diaphragm 4 of the objective 2, 3 and the diaphragm 11 having an annular opening. These real images lie on a curved surface 10. The annular opening in the diaphragm 11 corresponds to a zone in the reflecting condenser which lies between the points 12, 13, and 14, 15. In a modification a narrow silvered zone on the surface 9 produces the same result. Numerical data are given in the Specification.

Title: Improvements in or relating to the manufacture of compound sheet materials
IPC: C09J5/02
Filed: 1944-07-05
Abstract: 595,629. Compound sheet materials. McGILL, J. H., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. July 5, 1944, No. 12786. Addition to 570,840. [Class 140] The method for production of compound sheet material according to the parent Specification is modified in that that sheets are assembled while the thermoplastic substance is in a tacky condition due to the presence of solvent. Subsequent heating removes the solvent and gelatinizes the polyvinyl chloride. In an example, the sheets are coated with a polyvinyl chloride mixture as in example 1 in the parent Specification, the sheets heated to set this mixture, and the same polymethyl methacrylate solution applied. The sheets are then assembled by pressure without drying off the solvent. Alternatively, the solvent is dried off and one of the surfaces then rendered tacky again by applying a mixture of benzol and methylated spirits. The compound sheet is then dried at 100‹ C. and festooned in a stove at 132‹ C. for one hour.

Title: Improvements in or relating to electric glow discharge lamps
IPC: H01J17/00
Filed: 1920-05-10
Abstract: 145,400. Filippo, H., Lely, D., and Naamlooze Vennootschap Philips' Gloeilampenfabrieken. June 20, 1919, [Convention date]. Vacuum tubes.-In discharge lamps containing a gas such as helium, a smaller quantity of a rare gas of higher atomic weight is added to prevent disintegration of the electrodes; the cathode drop is normal and the light proceeds mainly from the cathode. Starting on continuous current without the use of auxiliary means is facilitated by employing at the cathode a wire or pointed metal sheet at a short distance from a flat anode. In lamps for alternating current both electrodes are of the same size and are arranged at a short distance from each other; both take part in the emission of light. Specification 125,201 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following features : - The electrode may be of pure aluminium or of iron. A series resistance, for example, 5000 ohms, may be arranged within the bulb or cap; it may consist of a thin wire wound in a spiral on an insulating core which is itself wound on a larger core. For advertising or signalling, the cathode may be in the form of a letter or figure; when alternating current is used, both electrodes together form a letter or figure. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to switching networks for communication systems
IPC: H04Q3/52
Filed: 1956-04-27
Abstract: 788,837. Automatic exchange systems. WESTERN ELECTRIC CO., Inc. April 27, 1956 [April 28, 1955], No. 12992/56. Class 40 (4). In a gas discharge switching network in which potentials are applied to selected ones of a number of terminals at each end of the network to establish or disestablish a conducting path across the network, a gas discharge tube having two electrodes defining a main discharge gap and having a starting electrode, has one main gap electrode connected to one of the terminals of the switching network and the other main gap electrode connected to a potential source, and is such that a potential of one polarity applied to the starting electrode establishes a path across the network while a potential of the opposite polarity disestablishes the path. In Fig. 1 subscribers 1 and 2 are connected to terminals 6 and 7 of the network and terminals 11 and 13 of the network are connected to trunks 24 and 25. Gas discharge triodes 3 and 4 are connected to terminals 6 and 7, and triodes 27 and 29 are connected to terminals 11 and 13 with their anode and cathode connections reversed as compared with triodes 3 and 4. If subscriber 1 wishes to connect with trunk 25, circuits 10 put positive and negative potentials on the start electrodes of triodes 3 and 29, respectively, causing each tube to fire, due to potential sources 9 and 14, and connecting the sources 14 to terminals 6 and 13. Switches 23 are moved manually or automatically to apply breakdown potentials to all the tubes 26 extending to idle junctions of the network and only one of the available parallel paths strikes as the current is limited by the resistors 12 in the triode circuits. The chosen path may be that having the shortest ionization time or that having the lowest impedance. A talking path is thereby set up through the network with a ground return over capacitors 20. To terminate the connection, circuits 10 apply negative and positive potentials to the starting electrodes of triodes 3 and 29, respectively, causing triode 3 to discharge between start electrode and anode and causing triode 29 to discharge between start electrode and cathode, in each case disconnecting battery 14 from the switching network to extinguish the talking path. When the circuits 10 remove potential from the start electrodes relaxation oscillations produced by condensers 17 extinguish each of triodes 3 and 29. Switches 23 are now restored to an idle position although they may be so restored at any time after the path has been established as it is held by batteries 14. Fig. 2 shows a preferred form of the circuits 10 in which tubes 30 and 33 are ionized by the field set up by coil 31, when connected to an A.C. source 38, and permit the application of positive and negative voltages to the start electrodes by setting of the switches 32 and 34. The switching network and application of marking potentials may be as described in Specifications 704,108 and 779,984.
