Patent GB-357133-A (GB)
Title: A process for obtaining carbon from flames
IPC: C09C1/48
Filed: 1930-06-13
Abstract: <PICT:0357133/III/1> Relates to the formation of carbon black by deposition on electrically charged conductors inserted in a luminous flame and consists in the employment, as fuel for the production of the flame, of petroleum or other mineral oils, residues, distillates or extracts therefrom, e.g. an aromatic material extracted by liquid sulphur dioxide from a mineral oil, or liquid or semi-liquid residues having a high carbon content obtained from coal carbonization, or other organic materials giving a smoky flame in such gases as air or oxygen or nitrous oxide.  Impurities included in the carbon are removed by solvents.  The yield of carbon may be increased by maintaining the carbon deposit at a uniform temperature or by cooling it by imparting a slow movement to the depositing surface, e.g. by a continuous or intermittent rotation or by removing the deposit therefrom.  The quantity or quality of the deposit may be varied by varying the fuel or the conditions of combustion, e.g. by varying the proportion or pressure of the gas supporting the combustion, or by varying both. The voltage employed may vary between 12 volts and that which will disrupt the flame.  Direct or alternating current may be employed and the conductors may be metallic or may consist of porous refractory material in contact with metallic conductors.  When using direct current, positively and negatively charged conductors are inserted in the flame, and with alternating current, one or more charged conductors are situated near the zone of maximum brightness of the flame.  The burner may be used as one of the conductors; with alternating current the burner and one of the terminals of the generator may be earthed.  Different qualities of carbon black are obtained, when using two depositing conductors, by separately removing the carbon deposited thereon. As shown, a revolving metal or other conducting roller A, covered with an absorbent non-combustible material such as asbestos, is mounted in a fixed cylindrical reservoir B provided with a slot B<1> and supplied by a pipe D with oil into which the roller dips.  The reservoir B is mounted in a metal casing C slotted at F and supplied by pipes E<1>, E<2> with air &c., a baffle X serving to prevent turbulence in the gas.  Mounted above the slot F is a slowly-revolving metal roller G which may be hollow so as to be capable of being heated by circulating gases &c. or cooled by water, the deposit being removed from the roller by a scraper. The flame formed is a long flat one, and the necessary potential difference is established between the roller G and the box C, reservoir B or the roller A.  Instead of the roller G, metal rods or gauze may be employed.  Two examples are furnished in which kerosene and an aromatic liquid extracted therefrom are employed respectively.  The Provisional Specification states also that p non-luminous flames may be employed and that the conductors may be situated near the flame.

IPC: B67D7/16
Filed: 1929-06-13
Abstract: 313,609. Soc. Hardoll Etablissements Hariveau et Dolimier et RenÚ Porte et Cie RÚunis. June 15, 1928, [Convention date.]. Liquid-meters.-A valve system for fixed-chamber apparatus with an automatically actuated quick-throw valve is arranged so that the changeover will not take place until discharge is complete. The double valve 6 determines the connections between the chamber 1, 2 and the supply and discharge pipes 7, 8. A piston 3 is connected to the valve 6 through a lever 4 and spring 5. A sector 11 rigid with the lever 4 carries rollers 12, 13 or a cam making contact with the upturned end 16 of a lever 14 to which a depending rod 17 is attached. The latter is connected to a lever 18 rigid with a pin 19 to which levers 21, 20 are also keyed. The lever 20 bears on the stem of a valve 23 in the supply pipe 7, while the lever 21 has a forked end 29 for engaging the rod 32 on the float 33. If one chamber is filled before the other is completely emptied, the float 33 being lifted permits the first movement of the piston 3 to be transmitted to and close the valve 23, Not only is supply thus stopped, but a bye-pass 26 allows the filled chamber to discharge by way of the pipe 28. The reversing movement is thus checked until the float rod 32 holds up the lever system 21, 18, 20 from interference with the stem of the valve 23. The device is applicable to apparatus in which the piston 3 and the valve 6 are replaced by a single member.

Title: Improved epoxy resin compositions
IPC: C08G59/40
Filed: 1956-06-13
Abstract: Epoxy compositions suitable for use as coating, adhesives, potting compounds, castings or laminates consist of epoxy compounds having on the average more than one epoxy group per molecule and, as curing catalyst a hydrazide having the general formula: <FORM:0842867/IV(a)/1> in which R is an organic radical having a valency of 2, 3 or 4, n is 0 or 1, Z is an amino, hydroxyl, or carboxylic/acyl hydrazide group and a is in intiger one less than the valency of R. Suitable epoxy compounds are those produced by reacting epichlorhydrin with polyhydroxy compounds, by epoxidising e.g. with hydrogen peroxide and formic acid, unsaturated compounds e.g. fatty oils or copolymers of butadiene with styrene, acrylonitrile or acrylic acid.  The mixture of the epoxy compound and hydrazide has a reasonable shelf life and can be heated and recooled repeatedly without permanent hardening.  The rate of cure can be accelerated by addition of activators e.g. lead octoate and zinc-octoate-diethylaminopropylamine.  Preferably 3/4 mol. dihydrazide is used per epoxy equivalent of the resin.  In examples the following hydrazides are used to cure commercial epoxy resins. (1) sebacic (2) adipyl (e) azelayl (4) adipyl azelayl (5) succinic (6) malonyl (7) oxalyl (8) hexahydro terephthalyl (9) isophthalyl (10) isophthalyl with mica, aluminium silicate and iron oxide as fillers (13) p-aminobenzhydrazide (14) the hydrazide of 2,4-dihydroxy benzoic acid (15) p-hydrozybenzhydrazide (16) 3, 5-diaminobenzhydrazide (17) the dihydrazide of m-benzene-bis oxyacetic acid (18) the trihydrazide of citric acid.  In Ex. (19) the epoxy resin was first reacted with sebacic acid and then cured with isophthalyl dihydrazide.  In Ex. (20) an epoxy resin was produced from epichlorhydin and the reaction product of p-hydroxybenzoic acid with polyethylene glycol, and then cured with isophthalyl dihydrazide.  In Ex. (21) an epoxy resin from cashew nut shell liquid was cured with isophthalyl dihydrazide in the presence of "Benton 34" and diethylaminopropylphthalimide-salicylic acid salt.

Title: Method for manufacturing porous ceramic products
IPC: B28B7/34
Filed: 1975-05-02
Abstract: 1466016 Extruding porous ceramic S FERNHOF 2 May 1975 [6 May 1974] 18588/75 Heading B5A [Also in Division C1] In a method of manufacturing porous ceramic products comprising the steps of mixing raw clay with pellets or chips of expanded polystyrene or other plastics material (specified) and shaping, drying and baking the resulting mixture, in which baking the plastics particles are eliminated or reduced in volume to leave pores in the baked products, during the shaping process the plastics particles are heated in parts of the shaped mixture that are required to have a higher density than the remaining paths thereof until the particles are eliminated or reduced in volume. The plastics particles may be mechanically pressed inwardly from the surface of the moulding during the selective heating. The method is particularly suitable for the production of frost-resistant bricks, wall tiles and ceramic piping having a dense, smooth inner surface. Referring to Figs. 1 and 2, clay containing the particles of plastics is heated during extrusion through extrusion head 2 into die opening 3 by electrically heated plates 5 mounted on an annular member 4 over an insulating ring 6. As a result the material leaving the press will have a compacted outer skin but a porous core. Figs. 3 and 4 depict an extrusion press wherein the conical core 9 is provided with plates 5 heated by electricity supplied through cables 8. The plates can be offset or staggered, as shown in the bottom of Fig. 1, and the edges inclined or bevelled. The edges may have a surface of hard metal. The heating device can alternatively be in the form of cutter blocks, rollers, combs or porcupine spikes.
Patent GB-130011-A (GB)
Title: Improvements in and relating to Projector Arc Lamps.
IPC: H05B31/00
Filed: 1917-12-14
Abstract: 130,011. Brockie, J., and Johnson & Phillips. Dec. 14, 1917. Arc lamps.-In a projector, a carbon-holder moves axially in, and rotates with, a sleeve supported by a carriage which slides to strike the arc. The arc-striking movement may be applied to one carriage or to both. As shown, each electrode passes through a sleeve 8, the forward end of which is longitudinally divided and is closed by a spring 12 so as to compress a split contact bushing 11 on to the carbon. The carbon may be grooved or made of rectangular or other section ensuring rotation of the carbon with the sleeve. Heat-radiating flanges 13 are provided at the front end of the sleeve, and a fire-proof shield 14 is fitted on the sleeve of the positive carbon. Within and beyond the rear part of the sleeve extends a tube 7 threaded internally to co-operate with a thread on the carbon-holder 3, into which the carbon may be dovetailed. Gear-wheels 22, 23 rotate the sleeve and tube at different rates so that a slow forward motion is imparted to the carbon. The sleeve is held on a carriage 9 by hinged clasps 10 fastened by latches and pins. Thus, the sleeve, tube, and carbon can easily be removed in one piece. Brushes convey current to the sleeve, or a single brush may serve also as a bearing for the sleeve. The brushes may be of copper gauze backed by steel springs. The sleeve and tube are rotated by bevel-gear, shafts 25, 25<1>, and couplings 70, of which the sleeve parts are of fibre. One shaft 25' is driven by a shunt electric motor 31 through a worm and a clutch 36 controlled by a handle 35. A chain 27 transmits motion from this shaft to a sleeve on a shaft geared to the second shaft 25. Handles 32. 33 on the co-axial sleeve and shaft are normally coupled for motor feed. but are uncoupled when independent hand feeding is required, the motor being unclutched. The speed of the motor may be regulated by a series resistance switched in by hand or automatically, or by a brake applied by the arc-striking coil. In the described arrangement, an armature attracted by the core of the series arc-striking coil 44 opens a short circuit to a resistance in series with the motor. The core 43 is connected by link-work 41, 40, 39, 38 to the negative carbon carriage, which slides on its standard 48. Both standards are insulated from a supporting-platform 49, which can be raised and lowered or tilted about two axee at rightangles, being mounted on three ball-and-socket joints 50 vertically adjustable by screws 51.
