IPC: C08F16/12
Filed: 1928-07-06
Abstract: 294,474. I. G. Farbenindustrie Akt.- Ges. July 23, 1927, [Convention date]. Polymerized vinyl compounds.-Masses resembling rubber are obtained by polymerizing vinyl compounds such as vinyl esters of organic acids or vinyl ethers and incorporating nitrogeneous organic compounds which are solid at room temperatures, such as proteids or their degradation products such as peptones, peptides, diketopiperazines, and amino acids, and other nitrogeneous compounds preferably of high molecular weight, or aromatic hydrocarbons which are solid at room temperature, such as naphthalene. Mixtures of both may also be used. The polymerization is effected by heating, chemically active radiation or other known means and in the presence or absence of accelerators. It is stated that benzoyl peroxide and organic acid anhydrides in conjunction with oxygen or agents yielding oxygen have already been used as accelerators of the polymerization of vinyl compounds. The products mav be vulcanized in the usual way with or without accelerators, and fillers and plastifiers may be added. In the examples vinyl acetate is emulsified with a casein solution and treated with radiation from a mercury vapour lamp; albumen is suspended in vinyl acetate and heated with a small quantity of benzoyl peroxide, with shaking or stirring, an elastic film or compact mass being obtained, or the reaction mixture may be poured in a viscous state upon a horizontal plate and the polymerization completed by radiation; glycocoll is suspended in vinyl acetate and benzoyl peroxide, and treated as in the preceding example; naphthalene is dissolved in vinyl acetate and benzoyl peroxide and treated as in the preceding example; and naphthalene is added to a solution of polymerized vinyl acetate in benzene and the solvent is distilled off. The Specification, as open to inspection under Sect. 91 (3) (a) states that vinyl esters of inorganic acids may be used as starting materials. This subject-matter does not appear in the Specification as accepted.

Abstract: 1495803 Helically winding and unwinding narrow strip material GOODYEAR TIRE & RUBBER CO 13 May 1975 [21 Oct 1974] 20067/75 Heading D1J A tyre building strip S and an underlying strip of non-adherent separating material C are together wound free of twist onto a reel 16 in a continuous plurality of helical covolutions in successive layers alternating in helical lead; and the strip S is then fed off the reel free of twist to a tyre building machine 14, Fig. 3 In Fig. 5 a truck 22 is coupled at 28 to a platform 31 that carries a screw thread 45 extending through a fixed nut 47. Rotation of the screw thread 45 by a motor 41 causes the platform 31 to be displaced, and limit switches (58, 60), Fig. 1 (not shown) cause a change over of clutches 54, 56 at the end of each traverse motion in a manner effecting a reversal of drive to the screw 45.  When the cylinder 16 is fully wound it is uncoupled from the platform 31 and moved to a paying out station, Fig. 3, where it is coupled to a platform 78 of a second traversing mechanism 80. The strip S and separating material C are wound off via a displacement sensing means 100. If the strips tend to move laterally relatively to the sensing means 100, the sensing means generates a signal which is communicated to a control valve 97 on the platform 78. The control valve 97 thereupon adjusts the effective pressure at one side or other of a piston 94 in an hydraulic cylinder 93 sufficiently to cause the piston 94 to move the trolley 22 to a setting in which the strips being wound off the cylinder 16 are in correct alignment with the sensing means 100 and thereby with a tyre building machine 14 The non-adherent separating material C is wound up onto a take-up roll and the tyre building strip S is fed to the lyre building machine 14. In Fig. 3 a conventional brake 88 cooperates with a brake disc 91 fixed on the shaft 84 to provide a back tension to the strip S as it is pulled off the cylinder 16.
Patent GB-910828-A (GB)
Title: Preassembled pipe coupling and method of forming same
IPC: F16L21/04
Filed: 1960-06-08
Abstract: In a method of coating a pipe coupling (see Group XXVIII) the metal parts of the coupling are first freed from dirt, lubricant and rust and coated with a release agent which is applied, e.g. to the threaded ends of bolts, by dipping, or with a brush or caulking gun. Prior to applying the release agent, the coupling may receive a coating of a liquid phenolic resin composition.  The coupling is then sprayed at room temperature with a primer consisting of coal tax pitch, epoxy resins and an aromatic solvent such as high-flash naphtha.  The free threaded ends of the bolts and the nuts are then protected and the primer is partially cured by exposing the coupling to a current of hot air or gases.  The coupling is immediately immersed for a few seconds in a molten bath of a coal tar-enamel composition.  The latter coating is then allowed to congeal by rotating the coupling above the bath and the coupling is finally cooled at room temperature.  The process may be carried out in an apparatus in which the coupling, fastened to a support, is suspended from an overhead chain conveyer and is transported successively to a spraying station where the primer is applied through nozzles, a heating station where hot air or gases are delivered by a blower, a dipping station where a vertically movable insulated tank is heated to maintain the coal tar-enamel in a molten state and finally to a cooling station.

Title: A new or improved method and apparatus for the treatment and disposal of ash
IPC: F23J1/00
Filed: 1949-08-02
Abstract: 658,597. Treating ash and ash shrrry; filters. MACINNES, N. B. Aug. 2, 1949. No. 20097. Convention date, Aug. 11, 1948. [Classes 46 and 111] In the treatment of ash removed from chimneys, boilers and the like by mixing it with water to form a slurry and directing the slurry into a sump or tank, the velocity of entry of the slurry is reduced and the slurry in the tank recirculated to assist settling, the ash being finally settled on a filter bed within the tank and removed when the tank has been emptied of all surplus liquid. Slurry from a feed pipe 43, Figs. 3 and 5, is fed to T-pieces above a ramp 19 from which the slurry flows through gate-like sluices 21 on to a lower ramp 20 and thence into a settling tank 1 through further sluices 18, Fig. 2. Some ash settles on a gravity or sand filter bed 7 while water together with fine ash passes through a filter screen 12 into a launder 11 and flows along it to an auxiliary tank 2, Fig. 4. Slurry from the auxiliary tank sump 9 is passed by pump 27 to a recirculating pipe 40 extending the full length of the ramp 19. when the auxiliary tank is nearly full. This recirculation is continued until the capillary action of the ash is broken down. Slurry is then delivered by pipe 45 to the settling tank 1a of the second unit. and all the slurry from the first auxiliary tank is pumped by pump 27 to the recirculation pipe 40a of the second settling tank. Slurry in the first settling tank is now allowed to settle after which supernatant liquid is drawn off through inlets 24 of a decantation tube 23 and liquid from below the bed 7 through pipe 5, all by pump 27, to a waste pipe 31. When cracks appear in the surface of the settled ash the pumps are stopped and the ash then loaded into trucks by a grab 47 on a crane 46. Each auxiliary tank 2 is provided with an overflow launder 14 connected by pipes 16 and 17 to pump 26 or 29, permitting continuous overflow to the waste pipe 31 during operation of each complete unit, since the unit is too small to hold all the water used during the operation period. If desired, a third unit may be provided the settling tank of which could receive the overflow from launder 14 of the first auxiliary tank, while the second unit is being cleaned out, this third unit being the next one to be brought into operation. If the auxiliary tank overflow water from any one unit is to be used again for washing ash down sluices in the first part of the process, the auxiliary tank is lengthened to render the water entirely free of ash, and a tank for storage purposes, and a further pump, are provided. The water may be corrosive and should be tested before re-use. The filter bed 3 may comprise a layer of builder's blue stone or granite in pieces of ¢ in. to 2¢ in. diameter. a layer of gravel of in. diameter, and finally a layer 2 ft. 9 in. deep of clear river sand, fine granite, or quartose sand. Spaced angle irons 6, the ends of which rest on the floor 3 just below the surface of the bed 7. prevent disturbance of the bed 7 by the grab 47.
