Title: Feed water supply apparatus for high pressure steam boilers
IPC: F22D3/08
Filed: 1929-04-08
Abstract: 309,995. Friedmann, L., Friedmann, M., and Schopp, N., (trading as Friedmann, A., [Firm of]). April 19, 1928, [Convention date]. Feedwater, supplying. - In gravity-feed apparatus comprising two chambers 10, 40 which are alternately filled with feed-water through a pipe 4, and which are then placed in turn in communication with the boiler steam space through a pipe 8 to allow the water to flow into the boiler through pipes 20, 50, the admission of boiler steam. to each chamber through the pipe 8 is controlled by the pressure in the other chamber. Boiler steam is supplied through a throttle valve 7 to the feed injector 1 or the like delivering water to, say, the chamber 10, its entrance to the other chamber, which is now under boiler pressure, being prevented by a non-return valve 41. Boiler steam enters the chamber 40 through a valve 24 forming part of a compound valve 14 on the chamber 10 and flows through a pipe 19 and ports 56 in a compound valve 44 on the chamber 40. When the chamber 10 is full, the water passes through a small aperture 13 to an auxiliary chamber 12 or through a loaded valve, and the back pressure set up acting upon the er.larged end 29 of the compound valve 14 lifts it against the downward pressure of the boiler steam acting upon the valve 25 and closes the valve 24. The boiler steam is thus cut off from the chamber 40 and the steam remaining in the chamber flows through the pipe 19 and ports 26 in the valve 14 into the chamber 19, where it is condensed. The valve 44 is then forced downwards by the boiler steam, water enters the chamber 40 through the non-return valve 41. steam flows through the valve 54, pipe 19 and apertures 26 into the chamber 10, and the cycle of operations is repeated. In a modification, in place of the pipe 19, the space 17 around the valve on each chamber is placed in direct communication through a pipe with the other chamber, and non-return valves are provided to prevent the passage of boiler steam from one chamber to the other.

Abstract: 781,333. Moulding aircraft propeller blades &c. WARNKEN, E. P. April 16, 1955, No. 11018/55. Class 87(2). [Also in Groups XXVI and XXXIII] A blade of aerofoil section for example an aircraft propeller blade, comprises a vane portion formed of a plurality of substantially parallel elongated laminations disposed in a pack one on the other, and a root portion formed of laminations which extend transversely of and adjacent one end of the vane portion, the laminations being impregnated with a resin and being moulded to form the blade. The laminations may be of fibre-glass cloth impregnated with phenol-formaldehyde type resin. The laminations 14 forming the vane portion and the laminations 16 forming the root portion of a compressor blade are shown in Figs. 4 and 5, the root-forming laminations 16 being formed as convoluted rolls one on either side of the laminations 14. The laminations 14 are not all of the same width. In a further embodiment, Fig. 8, the root-forming laminations 23 are formed as a pack having an opening 24 therethrough, the pack being passed over the pack of vane-forming laminations. A moulding machine for forming the blades is shown in Fig. 7, and comprises a fixed die 28 supported on a stationary press plate 27<SP>1</SP> carried on a frame 27. An upper movable die 33 is carried on a platen 32 slidable on columns 31. The laminations 14, 16 are supported on the lower die 28 and the upper mould is moved downwardly by the hydraulic ram 46. The fibres at the root end of the blade are gripped by shoes 43, 44 during the vane-forming operation. The root-forming dies 39, 42 are disposed in slots 38, 41 in the fixed and movable dies 28, 33 respectively the two root-forming dies being moved towards each other by the hydraulic rams 51, 52 so as to mould the laminations 16 into the blade root portion, the root-forming operation being subsequent to the vane-forming operation. The dies may be heated to a temperature such that the resin impregnant can flow. The invention is also applicable to the construction of helicopter rotor blades, and to ducted fan blades of ducted fan type propulsion units.

Title: Improved epoxide resin compositions
IPC: C08L63/00
Filed: 1956-04-11
Abstract: Epoxide resin compositions capable of thermosetting in admixture with a hardener for epoxide resins and suitable as adhesive for glass-to-glass and metal-to-metal surfaces, e.g. as structural adhesives in the aeroplane industry, consist of 100 parts by weight of low molecular weight epoxide resin and 3-60 parts of a liquid copolymer of 55-74 parts butadiene with 45-26 parts acrylonitrile. The compositions are used particularly to impregnate fibrous glass. Silica, alumina, and powdered aluminium may be used as fillers.  The epoxide resins are preferably prepared from bis-phenol and epichlorhydrin in presence of alkali or from glycerol and epichlorhydrin in presence of boron trifluoride catalyst.  Suitable resin may also be prepared by epoxidizing unsaturated hydrocarbon oils, e.g. soybean oil or unsaturated copolymers of butadiene with hydrogen peroxide. Curing may be effected in presence of the usual organic acid anhydrides, amines, amides, diisocyanates, ureaformaldehyde resins, glyoxal and aromatic polysulphonic acids.  A liquid butadiene-acrylonitrile polymer is obtained by reacting butadiene and acrylonitrile in water with Na lauryl sulphate as emulsifier and potassium persulphate and tertiary dodecyl mercaptan as catalyst.  Examples of compositions are: (1) epoxide resin 100 parts, chlorendic anhydride 195 parts, butadiene copolymer 17 parts, powdered silica 7 parts; (2) as in (1) with addition of dimethylbenzylamine; (3) as before with maleic anhydride or hexhydrophthalic anhydride in conjunction with the dimethylbenzylamine; (4) dicyandiamide used as curing agent; (5) metaphenylenediamine as curer; (6) dihydrazides as curers; (7) abrasive sheets are obtained by coating with abrasive a vulcanized sheet impregnated with the resinous composition.  Glycerol type epoxide resin were also used; (8) a moulding composition comprises an epoxide resin, butadiene copolymer and phthalic anhydride; a table is given of the variation in curing times with various proportions of epoxide resin and copolymer; (11) the composition was used to impregnate layers of non-woven linearly aligned glass fibres which were made into pipes and tubes. Mercaptobenzothiazol, tetraethylthiuram disulphide and zinc oxide may be added as cure accelerators.
