Patent GB-964437-A (GB)
Title: Stable burning solid propellents
IPC: C06B23/00
Filed: 1961-05-31
Abstract: A solid propellent composition comprises a cured intimate mixture of a non-metallic oxidizing salt, a resin binder, and, as a resonance suppressor, aluminium, silicon, graphite, or mixtures thereof, in an amount not greater than 4% by weight of the total composition.  The binder is preferably a cross-linked urethane type synthetic resin formed by reacting a diol or dithiol with a diisocyanate or diisothiocyanate in the presence of a cross-linking agent.  The Specification lists many suitable reactants.  The diols and dithiols include polyesters prepared from dihydric alcohols and dibasic acids and preferably mixed with olefines, polyalkylene ether glycols, and polysulphides.  The polyurethane reaction may take place in the presence of a plasticizer, curing catalyst, and solvent at a temperature of 70-180 DEG  F. Preferably there is used a slight excess of the isocyanate component over the hydroxy component. Other suitable binders are asphalt, synthetic rubber, polysulphides, and phenol-aldehyde, polyester, acrylate and polyalkylene resins. Such binders are described in Specifications 579,057, 883,586 and 941,745, and U.S.A. Specification 2,479,828.  Nitro-substituted acrylic resins or polyurethane resins or nitrocellulose-plasticizer binders may also be used.  The resonance suppressor is preferably in finely divided form and when aluminium is used, the particles are preferably spherical. The oxidizing salt may be a chromate, dichromate, permanganate, nitrate, chlorate, or perchlorate of ammonia, hydrazine, or guanidine.  The propellant may also contain burning rate modifiers, anti-oxidants, wetting agents, and anti-foaming agents. Examples relate to polyurethane compositions in which the polyurethane is formed from polypropylene glycol and tolylene diisocyanate with glycerol monoricinoleate as a cross-linking agent; dioctyl azelate is used as a plasticizer and ferric acetylacetonate as a catalyst.  Ammonium perchlorate is the oxidizing salt and other ingredients are copper chromite and carbon black as burning rate modifiers, phenyl betanaphthylamine as an anti-oxidant, lecithin or a mixture of sorbitan oleate and polyoxyethylene esters of mixed fatty and resin acids as wetting agents, and stannic chloride.  The propellent mixture may be introduced directly into a rocket chamber lined with an inert resin and cured therein.  Firing tests show that the presence of the resonance suppressor produces smooth pressure-time curves indicating an absence of resonant burning.

Title: Control systems for gas-fired appliances
IPC: F23N5/06
Filed: 1975-05-05
Abstract: 1509534 Burner controls VALOR NEWHOME Ltd 5 May 1975 [4 May 1974] 19713/74 Heading F4T A control system for an oven burner 18 of the type having a pilot burner 24 with a spark igniter 28 comprises three switches 38, 40 and 42 in series in the power supply line to a spark generator 30 for the igniter. The first switch 38, normally open, is closed when a tap 10 for gas supply to the pilot and main burners is opened. The second switch 40 is incorporated with a valve 26 in the pilot gas supply line in a timer mechanism 22 and is also closed when the valve 26 is opened. The third switch 42 is incorporated in the actuating mechanism of a valve 46 (normally closed) controlling the gas supply to the main burner such that when the pilot flame is detected by a thermal device 60 and bellows 48 expand, the switch, which is normally closed, is opened to cut off the power supply to the spark generator. Should the flame fail, the thermal device acts to close valve 46 and close switch 42 so that ignition can be reinitiated. The power supply to the spark generator is provided with stepping down and stepping up transformers so that the voltage through the switching circuit acting across the switches is reduced. A switch 36 is included in the circuit for manual actuation of the generator. Other methods of reducing the voltage or current through the circuit are disclosed. These include tapping off from the transformer with a high resistance in the tapping line. In one embodiment the switch 42 is placed outside the housing 44 and is actuated by a magnet positioned on the end of the lever 50. A spark generator is shown in Fig. 6. The switches are connected across leads 118 and 120 and when closed allow capacitor 126 to charge up and eventually discharge across a neon lamp 128 and trigger a thyristor 114 so that a capacitor 106 can discharge through a transformer 112 and produce a spark at the spark gap. Switching circuits are shown in Figs. 7 and 8 which are designed to initiate a timed burst of sparks when the gas tap 10 is opened so as to ignite any gas that may be leaking into the appliance and hence prevent explosion. The three switches 39, 40 and 42 are shown in Fig. 6 with switch 38 as a two position switch. The switch 38 can connect a capacitor 132 across the terminals of the generator to produce initial sparks. In Fig. 8 the switch 38 has a passing contact 38b which allows the capacitor 138 to charge up and cause the generator to spark.

Title: Process for the production of a building material mixture
IPC: C04B7/00
Filed: 1949-07-27
Abstract: A concrete composition is prepared by grinding or mixing one or more finely divided material from the group containing in chemical combination predominantly silicic acid, alumina and iron oxide the group consisting of both inert and latent-hydraulic materials with a second group consisting of one or more compound containing the oxide, hydroxide or carbonate of calcium or consisting of gypsum or anhydrous gypsum, in such proportions that if the first group contains a latent-hydraulic material, at least one inert material must also be present and also that in the final mixture the first group preponderates over the second group and silicic acid exceeds the alumina.  Specified inert materials are combustion residues such as fly ash from coal, blast furnace dust, zinc ashes, filter waste from zinc ore flotation, brick dust, breccia ground residues, used sand from industrial processes; latent-hydraulic materials are oil schist residue, blast furnace scum slag and granulated blast furnace slag.  The calcium compounds are hydrate of lime, quicklime, limestone and marl.  A subsidiary process which gives an initial mixture for the main process comprises burning coal dust with a ground calcium compound.  When the first group materials contain carbon the burning operation is conducted without using additional fuel, (see Group XII).  A porous product is obtained when materials containing zinc are used in conjunction with the alkaline calcium compounds from the hydrogen liberated.  The mixing water for the product may contain an acid which can dissolve limestone, or its salts, whereby a cauterization is effected.
