Title: Improvements in Atmospheric Gas Burners.
IPC: F23D14/04
Filed: 1916-06-05
Abstract: 104,976. Parkinson Stove Co., and Hickinbottom, F. June 5, 1916. Gas burners.-In an atmospheric gas burner for gas fires, cookers, geysers, muffle furnaces, radiators, &c., air is supplied to the centre of the flame or flames through one or more passages in the burner head, and the exits for the gaseous mixture are formed between deep parallel walls coaxial or parallel with the corresponding air passage and inclined to the vertical, the walls being provided with ribs or grooves. In one form, the annular burner head a, Fig. 2, has central air passages b converging towards the top', and the exits b' for the gaseous mixture are formed between the walls of the passages b and deep annular internal webs c on the burner mouth, triangular, semicircular, or other ribs or serrations being formed either on the contacting surface of each wall or of each web, so as to form a series of deep separate apertures. The inner surface of the air passage may be serrated in a vertical direction. In a modification, a sleeve is inserted between each web and the corresponding wall of the air passage, and ribs or serrations are formed on the outer surface of the sleeve and on the outer surface of the wall or the inner surface of the sleeve. Fig. 8 shows a ring burner in which a ring e with ribbed tapering sides e<1>. fits in a burner head a of channel-shaped crosssection. In another form, a gas-fire burner is provided with a series of elongated air ducts b, Fig. 11, and strips or bars e having vertically ribbed surfaces are arranged in the elongated exit slots for the gaseous mixture on each side of the air ducts b. The strips e or bars rest at their ends upon bearers f, Fig. 13, and are secured by clamping-plates g engaging their stepped ends. In other forms, the air ducts may be oval or square.

Title: Process for the preparation of a polyvinyl chloride extender resin
IPC: C08F2/00
Filed: 1976-03-02
Abstract: 1487991 Adjuvants for vinyl chloride suspension polymerization STAUFFER CHEMICAL CO 2 March 1976 [11 April 1975] 08251/76 Heading C3P The rheological properties of (a) the polymerizing mass and (b) the final product, in an aqueous suspension polymerization of vinyl chloride to produce a PVC extender resin, are controlled by carrying out the polymerization in the presence of a polyallyl compound and a propylene oligomer containing 3 to 7 units. The preferred polyallyl compound is diallyl phthalate, but many other polyallyl esters are specified. The propylene oligomer apparently acts as a viscosity control agent during polymerization by preventing the formation of porous resin particles which would absorb water. The quality of the product is thereby also improved. The polyallyl compound apparently controls the molecular weight of the polymer forming.

Title: Improvements in the manufacture and production of interpolymerisation products

Filed: 1938-03-18
Abstract: 512,703. Polymerization products. JOHNSON, G. W. (I.G. Farbenindustrie Akt.-Ges.). March 18, 1938, No. 8462. [Class 2 (iii)] Rubber-like interpolymerization products are made by treating in aqueous emulsion a mixture of a butadiene hydrocarbon, e.g., butadiene, isoprene or dimethylbutadiene, and an ethylene alpha-#-dicarboxylic ester, e.g., a fumaric or maleic acid ester, with oxygen or a substance giving off oxygen as a polymerization catalyst. If desired, other organic compounds capable of polymerization under the same conditions and having an unsubstituted methylene group bound by a double carbon linkage, particularly vinyl compounds, such as vinyl chloride, vinyl esters, acrylic acid or its esters, styrene and vinyl ethers may also be present. The products may be used for making oil-proof cables or hoses ; those having a high content of butadiene hydrocarbon are suitable for automobile tyres. The products can be vulcanized and worked up with fillers, especially fibrous materials, softening agents or dye stuffs. In examples, (1) butadiene is emulsified with fumaric acid diethyl ester in an aqueous solution of. sodium hydroxyoctadecane sulphonate, and polymerized after addition of potassium persulphate ; acrylic nitrile may be added to the polymerization mixture, (2) fumaric acid dibutyl ester and isoprene are emulsified in an aqueous solution of turkey red oil and a sodium alkylated naphthalene sulphonate and polymerized with addition of potassium persulphate, (3) fumaric acid diethyl ester is emulsified with butadiene in presence of sodium oleate and polymerized with addition of potassium persulphate, and (4) the reaction product from #,#-dichlordiethylether (1 mol.) and the amines prepared from train oil by converting the acids therein into nitriles and reducing is dissolved in a mixture of fumaric acid diethylether and butadiene and emulsified and polymerized in water containing potassium persulphate and hydrogen peroxide. The interpolymerization products from butadiene, fumaric acid diethyl ester and vinyl chloride, or acrylic nitrile, and from butadiene and maleic acid diethyl ester are also described. Specification 482,647 is referred to.

March 22, 1932, No. 8475. [Class 56.] The finishing moulds of a glassblowing machine are supported by a plate and are attached to their operating-arms by means which permit each of the mould sections to rotate about a vertical axis and to be adjusted horizontally on its arm. The mould sections 10, Fig. 2, rest on and slide over an horizontal plate 22, and each section is provided with a vertical pin 13, Figs. 2 and 5, which is journalled in the head 26 of a bolt 25. This bolt passes horizontally through a slot 27 in the mould arm 14 and is secured by a nut 29, but the slot 27 is of greater width than the bolt to permit lateral adjustment of the bolt, and with it the mould section, in an horizontal direction. The mould sections are free to swing about the axes of the pins 13, the movement being limited by lugs 30 which co-operate with stops 31 on the arms 14. Lugs 32, attached to the upper surface of the plate 22, engage recesses 33 in the moulds to centre the sections. A circular rib 35 on the plate 22 also engages recesses on the sections and guides them as they open and close. When the mould closes, the limited movement allowed to the sections ensures that they adjust themselves to one another, so that the faces 11 of the sections are in contact over the whole of their area.
