Title: Flexible resilient cellular resin products
IPC: C08J9/02
Filed: 1955-01-24
Abstract: Foams are obtained by reacting complex resins containing free isocyanate groups and a foaming agent which is water and/or a carboxylic acid in the presence of a curing catalyst.  The resin is one of two types, the first being obtained by reacting in sequence from 64.5 to 84.5 mol. per cent of a diisocyanate, from 2.5 to 23.5 mol. per cent of a dihydric alcohol which may be a polyglycol of high molecular weight, from 2.5 to 23.5 mol. per cent of a dicarboxylic acid, hydroxy acid or amino acid, from 0.59 to 8.7 mol. per cent water and from 1.08 to 16.3 mol. per cent of a compound having a functionality greater than two reactive with isocyanate groups.  The second type of resin is obtained by reacting in sequence from 55 to 85 mol. per cent of a dihydric alcohol, which may be a polyglycol of high molecular weight, from 1.7 to 18 mol. per cent of a polyester, from 0.42 to 6.9 mol. per cent water and from 0.84 to 12 per cent of a compound having a functionality greater than two reactive with isocyanate groups. Heating and time schedules are given for the preparation of the two types of resin.  The foaming mixture consists of from 82-99 per cent by weight of either type of resin or a mixture of the two types, from 0.4 to 15 per cent of foaming agent and from 0.5 to 15 per cent of catalyst.  Fillers, which may be fibrous or metallic, plasticisers, pigments and solvents may be present.  Free isocyanates may be added to the reacting mixture and wetting-agents, polyester, polyamide, polyesteramide or polysulphide resins may also be present.  The catalysts may be metal or amine salts of organic acids, glycerol monoricinoleate, heterocyclic nitrogen bases, polycarboxylic acids, phenates and mixtures thereof.  The mixture is allowed to react at room temperature in a mould or in situ and may be after-cured at 125-250 DEG  F.  The products are resilient.  The Specification gives a large number of examples of the two types of resins, of polyesters, &c. to be used in making the second type of resin, of catalysts and of foaming mixtures formed from the resins, catalysts and water as foaming agent.

Abstract: 308,712. Florentin, J. M. F. D., and Kling, A. J. March 27, 1928, [Convention date]. Grant of Patent refused. Hydrogenation, destrutive. - In obtaining motor spirit by destructively hydrogenating heavy organic compounds under pressure the whole or a part of the heat necessary to bring the reaction chamber to the required temperature is furnished by admitting compressed hydrogen to the chamber at a temperature above the normal reaction temperature, the excess hydrogen being re-cycled. A liquid organic compound is fed by a pump H through a preheater C into a reaction chamber B. Hydrogen entering through a cock K is compressed in a compressor G, preheated in a heat interchanger E1 and blown through a perforated tube J into the liquid in B. Light hydrocarbons formed pass with the excess hydrogen into a dephlegmator F, from which the condensed hydrocarbons are withdrawn by a cock L. The hydrogen passes through cocks M, 0, and is cooled in a heat interchanger E2 before re-circulation by the compressor G. At intervals liquid is withdrawn from a cock I, and hydrogen from a cock P; this hydrogen is purified by active charcoal or liquid air condensation, and then returned to the circulation. Make-up hydrogen is added through the cock K. Specifications 253,507, 263,082 and 276,007 are referred to.

Abstract: 839,646. Clutch control. NAPIER & SON Ltd., D. Jan. 9, 1958 [Jan. 30, 1957], No. 3330/57. Class 80 (2). A coupling between shafts 11, 29 of e.g. a Diesel engine and a compressor, comprises a fluid coupling 16, which takes the starting slip and a parallel friction clutch 15 which is engaged automatically and the coupling emptied when a predetermined minimum difference exists between the speeds of the input and output shafts. The torque capacity of the friction clutch is such as to permit slip on overload which also automatically releases the clutch. Clutch and coupling arrangement.-A common input member 40 fast on the input shaft 11 carries the coupling impeller 50 and clutch input shell 41, the coupling turbine 52 and clutch output member being fast respectively with freely mounted pinions 18, 17 independently driving a countershaft 27 geared to the output shaft 29. The clutch is engaged by fluid pressure supplied through passages 45, 43, 42 to a piston 38. The fluid coupling is filled through passages 55, 54, 53 and drains at 56 when the supply is cut off. Control.-Two input pinions 60, 61, Fig. 2, fast with bevel side wheels 62, 63 of a differential gear are driven in opposite directions from the input shaft 11 and countershaft 27 (Fig. 1) by gears 60, 61 to drive the planet carrier 65 at a speed proportional to the difference between the speeds of the input and output shafts, such carrier driving a centrifugal governor 68. The initial high-speed difference causes the governor to move left a valve sleeve 69 supplying pressure fluid from an inlet port 71 through a port 72 to depress a relay valve 80 which then supplies pressure fluid from a manual shut-off valve 47 through lines 85, 55 to the fluid coupling 16 (Fig. 1) and closes a port 84 cutting the fluid supply to the clutch 15. When the speed difference falls below the predetermined value the governor cuts off pressure 71 from the relay valve 80 which is moved upwards by a spring 82 to close the coupling supply port 85 and supply pressure through the lines 84, 45 to engage the friction clutch 15. In Fig. 3 (not shown) the centrifugal governor is replaced by an equivalent positive displacement pump. In Fig. 4 (not shown) the input and output shafts 11, 27 (Fig. 1) each drive positive displacement pumps arranged in series in a closed circuit pressure in which actuates the relay valve. The planet carrier may drive a generator energizing a solenoid or electric motor which actuates the relay valve. According to the Provisional Specification the planet carrier and input shaft may drive separate centrifugal governors operating the relay valve through a differential linkage.
