Title: Improvements in gas expanded products
IPC: C08J9/08
Filed: 1948-06-04
Abstract: Cellular products are made by adding water and a chemical polymerization promoter to a non-aqueous liquid mixture comprising an unsaturated alkyd resin, e.g. diethylene glycol maleate resin, a monomeric monoethylenic compound, e.g. styrene, an inhibitor of polymerization, an inorganic carbonate or bicarbonate, a peroxide catalyst, e.g. t-butyl hydroperoxide or benzoyl peroxide, and an organic acid or anhydride capable of decomposing the carbonate, whereby, without supplying heat, polymerization of the mix occurs concurrently with its expansion.  The polymerization inhibitor may be hydroquinone, t-butyl catechol, or tetrachlorohydroquinone. The source of acid may be maleic acid or anhydride, benzoic, phthalic or acetic acid, or an alkyd resin of acid value 10 to 100.  The carbonate or bicarbonate may be the ammonium, sodium or potassium salt.  The mix may contain a thickening agent such as aluminium powder.  When maleic anhydride is used as the source of acid it copolymerizes with the monethylenic compound.  The Specification contains an extensive list of chemical polymerization promoters.  The following classes are specified: monoamines, e.g. dimethylamine, p-dimethylaminophenylacetate; sulphydryl compounds, e.g. ammonium hydrosulphide, n-hexyl mercaptan; hydrazines, e.g. phenyl hydrazine hydrochloride; alkylene polyamines, e.g. ethylene diamine, pentaethylenhexamine, and disalicylidene - polyethylenepolyamine; N - mono - alkyl monophenyl secondary monoamines, e.g. N-methylaniline, N - ethyl - p - toluidine; and methyl-poly (N,N - dialkylaryl - amines) such as 4,41-(tetramethyldiamino) diphenyl methane and bis - (p-dimethyl-aminophenyl) - methylenimine.  The expanded product generally has cells of sizes between 0.2 mm. to 5 mm. and largely interconnected.

Title: Improvements relating to axial-flow compressors
IPC: F01D9/04
Filed: 1959-05-04
Abstract: 856,599. Axial-flow compressor stator blade assemblies. GENERAL MOTORS CORPORATION. May 4, 1959 [June 16, 1958], No. 15121/59. Classes 110 (1) and 110 (3). In an axial-flow compressor, a ring of stator blades comprising inner and outer shroud rings interconnected by blades is supported from the casing by means of circumferentially distributed flexible metal members each fixed at one end to the casing by means of a nut and bolt assembly and at the other end to the outer shroud ring. The compressor shown in Figs. 2 and 3 comprises a rotor 28 carrying rotor blades 24 and a casing 30 carrying stator blades 26, also stationary shroud rings 80 disposed around the tips of the rotor blades. The stator blades are mounted at their outer ends in a supportring 25 comprising a channelsection ring-member 50 and a plain ring-member 52 secured together at 54, 56, and at their inner ends in a support-ring 27 comprising a pair of channel-section ring-members 34, 36 connected together at 40, 42. The stator blades assemblies are each made in two semi-circular parts. Each stator blade assembly is supported from the compressor casing 30 by means of obliquely-inclined flexible strip members 60 secured at their inner ends to the outer surface of the ring member 50 at circumferentiallyspaced intervals and at their outer ends to nut members 62. The nut members 62 abut against bushes 64 and are secured thereto by means of bolts 70. The stationary shroud ring 80 is similarly supported from the stator casing by means of flexible strip members 76 each secured at one end to the shroud ring and at the other end to a nut member 74 which is secured against a bush 72 by means of a bolt 82. The bolts 70 and 82 are disposed in circumferential alignment within a channel-section reinforcing ring member 68. The inner and outer supportrings 27, 25 are arranged to form seals with the rotor and rotor blade shrouds respectively. The adjacent ends of the stator blade support-ring segments 50, 52, also of the rotor blade shroudring segments 80, are locked together by means of a toggle looking clip 98, 102, as shown in Fig. 3. In the embodiment shown in Fig. 5, the flexible strips 124 supporting the outer stator blade support-ring 118, 120 are of U-shape and are connected to the casing 30 by means of a bolt and nut assembly 130, 126 disposed in the same transverse plane as the stator blades 26. In a further embodiment, the flexible strips supporting the outer stator blade support-ring are flat as in the first embodiment but are connected to the outer casing by bolt and nut means radially outwardly of the stator blades as in the embodiment shown in Fig. 5.

Abstract: 752,956. Embossing and printing machines. REIMANN, K. P. May 22, 1954, No. 15122/54. Class 100 (2). Apparatus for printing and embossing a web of flexible material 33 comprises a heated cylinder 12 around which is passed an endless screen 10 of woven wire presenting a pattern in relief, and endless blanket 11 coacting with the screen, a roller 19 for applying ink to the relief pattern of the screen and means for passing the material 33 between the screen and the blanket. The screen is passed over a roller 14 co-operating with an auxiliary roller 15. The inking roller 19 dips in a reservoir 20 and co-operates with a doctor blade 21. The blanket 11 is guided round the greater part of the circumference of cylinder 12 by a pair of rollers 16, 17. On the return path it passes over spaced rollers 18. One or more pairs of pressure-applying rollers 22, 23 bear on the blanket adjacent the point it leaves the cylinder. The pressure of these rollers is adjusted by mechanisms 25 attached to each end of their mounting 24. The flexible material 33 passes round roller 16 between the screen and blanket and leaves between roller 14 and a roller 30. The screen 10 is woven to provide raised points for instance at the crossing points of the strands, the raised points may form the outline of a flower, as shown in Fig. 2. Alternatively a relief design may be attached to the screen. The cylinder 12 may be heated by steam.

Title: Method of treating gases produced by gasification under pressure
IPC: C10J1/207
Filed: 1960-05-05
Abstract: In a method of producing long-distance supply gas, town gas or synthesis gas which has a low CO content, a carbonaceous fuel is gasified under pressure, e.g. 23 atmospheres, with oxygen or oxygen-containing gases, and with steam and/or CO2, and the resulting gas at the same pressure is contacted with a catalyst to convert CO in the gas to CO2 and hydrogen by reaction with steam in the gas, which is thereafter washed if necessary to reduce its CO2 content, and, after the gasification and before the conversion, the gas is subjected to a partial condensation with the addition of tar and/or oil, in addition to water to remove from it solid, liquid or polymerizable constituents which would adversely affect the catalyst employed for the conversion, while allowing appreciable quantities of oil and tar vapours to remain in the gas, mists and/or drops of liquid contained in the gas being removed therefrom before the gas is subjected to the conversion reaction. After the condensation the gas may be treated with a surface-active solid substance, e.g. in the form of a fluidized bed, which assists in removing the constituents at between 150 DEG  and 500 DEG  C., e.g. certain coals and cokes, silica gel, active argillaceous earth or chromium oxide on activated carriers. Whether so treated or not, the partially-condensed gas may be cooled by indirect heat exchange. The oil and tar obtained from the gas in the condensation may be returned into the pressure-gas producer to wet the solid fuels therein.  Refined oil and tar from the converted gas may be utilized for partial cleaning of the crude gas.  Tars, oils or mixtures thereof not originating from the method may be used for the condensation. The catalyst used may possess a hydrogenating effect. The gas leaving the condensing operation may be heated in counterflow with the out-going converted gas. The converted gas, by the addition of gases with higher calorific value and higher density, may be brought to the quality of long distance supply gas or town gas. Nitrogen or other inert gases with a higher density may be added to the introduced or converted gas or a mixture thereof.
