Title: Improvements in and relating to Wireless Signalling Systems.
IPC: H04B1/16
Filed: 1917-06-28
Abstract: 114,539. British Thomson - Houston Co., (General Electric Co.) June 28, 1917. Wireless telegraphy and signalling.-The damping-factor of a resonant receiving-circuit is reduced by connecting the circuit to a vacuum tube having a negative resistance. As shown in Fig. 1, the resonant circuit 3, 4 is coupled to the receiving-aerial 1, and the vacuum tube 5 is connected in series with a battery 11 and telephone 12 across the condenser 4. The vacuum tube 5 comprises a heated filament 6, a grid 7, and a third electrode 8, and the grid 7 is kept at a fixed potential by a battery 10, the device being adjusted so as to give a negative resistance, that is, the current between the third electrode and the filament varies inversely as the potential difference. By working near one end of the negative resistance portion of the characteristic, the vacuum tube 5 also acts as a rectifier, enabling the signals to be heard in the telephone 12. The negative resistance may alternatively be adjusted so that oscillations are generated of a frequency differing slightly from that of the received oscillations, thereby enabling continuous-wave signals to be received by the heterodyne method. A variable condenser 13 is shunted across the telephone 12, and the circuit thus formed may be tuned to the group frequency of the incoming waves. On account of the reduced damping, the system is highly selective even though the receiving circuit 3, 4 is closely coupled to the antenna, and to the detector circuit if a separate one is employed. In the apparatus shown in Fig. 2, the negative resistance tube 5 is separate from, and in parallel with, the detector tube 14. The negative resistance may also be arranged in a circuit inductively connected to the receiving circuit 3, 4.

Title: Method of hydraulically mining underground materials
IPC: E21C25/60
Filed: 1973-02-26
Abstract: 1424240 Hydraulic mining SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 26 Feb 1973 9301/73 Heading E1F A method of hydraulically mining mineral from an underground seam comprises digging at least two trenches 4, 5 in the surface of the earth to a depth at which the trenches at least reach into the seam, making at least one dipping passage extending between the passages and passing for at least the major part of its length through the seam, disintegrating mineral in the side walls of the passage by hydraulic action, transporting a slurry of the mineral and water through the passage towards one end thereof into one of the trenches, and lifting this slurry out of the trench to the surface of the earth. Preferably the mineral is disintegrated from the side walls of a passage by moving a jetting head up through the passage, which is preferably formed by drilling the seam. The passage is inclined in a dipping seam at the same angle as the dip angle of the seam.

Abstract: Particles of a mineral suitable as a filler for organic material and having a solubility less than 10-3 molar have an inner coating of a polyamine and an outer coating of an organic substance compatible with the organic composition to which the mineral is to be added as a filler, the organic substance, which is preferably the same as that to which the mineral is to be added as a filler, containing an acid hydroxyl group (e.g. a phenolic resin), a carboxyl group (e.g. acrylic acid), a carbonyl group (e.g. acetone or benzaldehyde), an epoxy group (e.g. an epoxy resin), a nitro group (e.g. nirtocellulose), or a group which is a sulphur analogue of one of the first three group (e.g. nitrocellulose), or a group which Minerals specified are clay, barytes, sphalerite (ZnS), rutile, kaolinite, mullite, and graphite.  The polyamine may be ethylene diamine, hexamethylene diamine, tetraethylene diamine, diethylene triamine, tetraethylene pentamine, or guanidine.  In Example 1, secondary Georgia kaolin is mixed with water to give a solid: water ratio of 1:4 and is stirred to assure dispersion, 0.4% of ethylene diamine is added as a 75% solution and mechanically mixed, and 0.4% of the polyester resin known under the Registered Trade Mark "Selectron 5003L" is added as a 2% emulsion formed by gradually adding dilute ammonium hydroxide to the agitated resin-water mixture to maintain the pH at 8 until all the resin has been dispersed.  The clay is flocculated by the addition of a sulphuric acid-alum solution, filtered, dried at 125 DEG C., and pulverized.  The treated clay is added to a polyester resin.  The amounts of ethylene diamine and of emulsified resin may be varied, and viscosity data are given in Example 2.  The resin may also be a phenolic resin, or a short-oil alkyd resin.

A document conveying apparatus as described in the parent Specification 1,094,189 is modified in that the document feeding sets of staggered rollers 67, Fig. 3, and document delivering sets of staggered rollers 80 are arranged to co-operate with the periphery of a rotary document supporting drum instead of with endless conveyer belts extending in a planar surface. In operation the documents to be reproduced are placed on a tray 24 against a paper guide 54 and fed manually into the bite of pinch rollers 74 in the path of which is positioned a lever 56 one end of which actuates a switch (MS-1, Fig. 1) of motor (MOT-1) driving a drum 25 on a shaft 51. Rotation of the drum imparts frictional angular displacement to a rubber roller 59, which through a set of intermediate rollers drives the pinch rollers 74. The pinch rollers advance the documents towards the document feeding rollers 67 mounted on shafts 68, 69, 70 in an axially staggered manner. A stationary platen 26 having a lens and an aperture for optical scanning of the documents is provided with fingers 96, Fig. 4, which coact with the rollers 67 on the shaft 70 to prevent damage to the documents being fed to the platen 26. The documents are delivered into a tray (27, Fig. 1) by a set of document delivering rollers 80 which are mounted on shafts 81, 82, 83 and arranged in an identical manner as the document feeding rollers.

Title: Improvements in compositions for the purification of gases
IPC: C10K1/20
Filed: 1929-03-27
Abstract: 309,585. Compagnie Internationale pour la Fabrication des Essences et Petroles. April 13, 1928, [Convention date]. Materials for purifying. - In purifying fuel gases from sulphur by passage over a composition comprising a single metal such as nickel, cobalt and copper or its oxide employed alone on an inert carrier such as clay, pumice or kieselguhr, the proportion of metal or oxide to carrier is such that the entire composition cannot retain more than 10 per cent of sulphur by weight. When the composition is regenerated by air or oxygen, the heat liberated does not destroy the activity of the metal. Thus when carrier clay is immersed in nickel nitrate and the salt decomposed, the nickel must not exceed 20 per cent of the mass so that the regeneration temperature is below 800‹ C.

Abstract: 553,330. Rivets. SWANK, E. R. July 16, 1942, No. 9908. [Class 89 (i)] Hollow rivets for connecting sheets together are expanded by wood screws. In the form for connecting dimpled sheets, the rivets have a countersunk head notched at 30, Figs. 1 and 2, for a nut to restrain the rivet from rotating during the screwing in of a wood screw 22. The cylindrical part 12 of the base leads to a conical part 26 with transverse slots so that insertion of the screw expands the rivet as shown in Fig. 1. A modified form of rivet for connecting sheets that are not dimpled has a flat under-surface on the flanged head to engage the flat sheet. The end of the hole, through the sheets, remote from the flanged head is countersunk for better engagement with the expanded rivet.

Similarly, if a plurality of pressing rollers of different heating temperatures, peripheral speeds and  surface hardnesses are selected, the specified optimum fixing conditions are set and the cleaning  action of the rollers and the prevention of a sharp drop in fixing temperature of the fixing roller 1  immediate after starting of paper passing are well accomplished and the optimum fixing processing is thereby accomplished. The similar results may also be obtained even if plural kinds of fixing rollers are selectively used.
