Title: Improvements in wheel cylinders for hydraulic brakes
IPC: F16D65/22
Filed: 1931-09-02
Abstract: 377,478. Fluid-pressure brakes. HALL, F. H., Cleeve Cottage, Holford, near Bridgwater, Somerset. Sept. 2, 1931, No. 24622. [Class 103 (i).] In brakes of the kind comprising a pair of shoes each applied to a drum by a hydraulic piston, the two pistons work in separate chambers or cylinders and a piston valve device whereby the quantity of liquid retained. in the cylinders is adjusted to maintain a constant clearance of the shoes from the drum to compensate for wear is provided in each cylinder inlet so that each shoe is separately adjusted. As shown, brake shoes 2, 3 pivoted at one end to an anchor plate 12 are engaged at the other end by pistons 6, 7 respectively. The pistons work in cylinders 8, 9 separated by a partition 10 and formed. in a single casting which is bolted at 13 to the anchor plate and includes a part 11 in which inlet plugs 23, 24 are screwed. The plugs carry a fitting 26 for connection to the pipe line. The adjusting devices each comprise a piston 16, 17 disposed in each inlet passage and carrying a soft washer 25 as described in Specification 371,659 for normally closing the entrance part 31, 32 of the passages from the part leading to the cylinders 8, 9. When the master piston is operated by the brake pedal, liquid is supplied to the passages 31, 32 forcing the pistons 16, 17 toward the cylinders 8, 9 against the action of springs 18 until these pistons each uncovers a bypassage (not shown) which permits liquid to flow from the passages 31, 32 to the cylinders 8; 9. When the pedal is released the pistons 16, 17 return to their seatings and a predetermined quantity of liquid is returned to the master cylinder irrespective of the quantity supplied to the cylinders 8, 9 so that the wear of each shoe is taken up. A bleed passage closed by a screwed plug is provided for the cylinders 8, 9 in the upper part of the casting. Passages extend from the cylinder chambers 81, 91 through the bolts 13 to drain liquid that leaks past the pistons. According to the Provisional Specification the cylinders for the two shoes instead of being cast in one unit may bear on each other end to end under pressure and a turncock may be provided in each inlet passage to cut out a defective cylinder.
Patent GB-1112995-A (GB)
Title: A method of decomposing urethane polymer
IPC: C08G18/48
Filed: 1966-06-02
Abstract: Polyether-based polyurethanes are decomposed into the polyether and an amine derived from the polyisocyanate used as starting materials for the polyurethane by contacting the polyurethane at a temperature of less than 250 DEG  C under normal or elevated pressure with at least one amine which is aliphatic, cycloaliphatic, aromatic or heterocyclic and at least one compound which is an alkali metal or alkaline earth metal oxide or hydroxide or aqueous solution thereof. Both polyurethane foam and polyurethane elastomers may be decomposed. In order to avoid separation of the amine resulting from the decomposition of the polyurethane from the amine used to decompose the polyurethane, the latter amine is suitably the same as that resulting from the decomposition.  Numerous amines may be used and exemplified are monoethanolamine, a mixture of monoethanolamine and aniline, an 80:20 mixture of 2,4-diaminotoluene and 2,6-diaminotoluene, cyclohexylamine, pyridine, diethanolamine and triethanolamine. The amines may also serve as a solvent system, but inert organic solvents may be used including the same polyether as that which is to be produced from the decomposition reaction. Suitable oxides and hydroxides are lithium, sodium, potassium, calcium and magnesium hydroxides, lithium oxide, sodium peroxide, potassium peroxide, magnesium oxide, calcium oxide and barium oxide. The amines and alkali or alkaline earth metal compounds may be mixed and then used as such or alternatively the polyurethane can firstly be reacted with the amine followed by the alkali or alkaline earth metal compound. When the polyurethane is completely decomposed the liquid produced is subjected to distillation under reduced pressure preceded, if a two layer liquid is formed, by a separation step in order to recover both the amine and the polyether.  The amines can be phosgenated to reform the polyisocyanate which can then be reacted with the recovered polyether to form a polyurethane.ALSO:Polyamines are produced by decomposing a polyurethane derived from a polyether and polyisocyanate at a temperature of less than 250 DEG  C. under normal or elevated pressure by contact with at least one aliphatic, cycloaliphatic, aromatic or heterocyclic amine and at least one alkali or alkaline earth metal oxide or hydroxide or an aqueous solution thereof. The amine which is derived from the isocyanate group of the polyisocyanate used in the production of the polyurethane is separated along with the polyether which are further separated by conventional means.  Suitably, the amine used to decompose the polyurethane is the same as that as will be obtained from the decomposition. In examples, a mixture of 2,4- and 2,6 - diaminotoluene and 2,4 - diaminotoluene alone are produced by decomposing polyurethanes derived from a mixture of 2,4- and 2,6-toluene diisocyanates and from 2,4-toluene diisocyanate respectively.

Title: Improvements in the process of producing compositions of fuel oil and powdered coal
IPC: C10L1/32
Filed: 1932-09-09
Abstract: Fuel consists of a dispersion of powdered coal in oil stabilized by a gelatinizer and ammonia gas.  The ammonia prevents setting at low temperatures.  Tar or other substance increasing the viscosity may be added, and nitrogen or air may be introduced during the mixing to produce froth.  Suitable proportions are 0.1--2.0 per cent of ammonia, and 0.5--5.0 per cent of paraffin, ceresin, ozokerite, montan wax, stearic or palmitic acid, alkali stearates or palmitates, or other gelatinizer.  In an example, 100 kg. of tar oil, 100 kg. of fuel oil, and 3--5 kg. of paraffin, ceresin, or ozokerite are mixed and treated with 1 per cent of ammonia gas; 200 kg. of powdered coal is mixed in.  According to the Specification as open to inspection under Sect. 91 dispersions of powdered coal in oil are treated with a gelatinizer to produce a thin gel which becomes fluid on agitation or under pressure.  Setting may be prevented by adding the substances sold under the Registered Trade Marks "Vaseline" or "Lanoline" with or without wool-fat pitch; oleic or other liquid fatty acid; Fremy acids, e.g. sulphonated castor oil or its ammonium compounds; or by homogenizing and producing froth by introducing nitrogen, air, or other neutral gas, or ammonia or other alkaline gas mixed or not with nitrogen or air.  For example 0.1--0.2 kg. of paraffin, 0.1 kg. of soft soap, 0.1--1.0 kg. of wool-fat, and 1 kg. of wool-fat pitch are dissolved in 100 kg. of tar oil; 100--110 kg. of powdered coal are mixed in, and the mixture is homogenized while 0.1--0.5 per cent of nitrogen and possibly with a trace of ammonia, is injected. Anthracene oil, and mazut are also specified as initial materials. This subject-matter does not appear in the Specification as accepted.
