Abstract: 409,827. Furnace walls. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.- (Bemitz Furnace Appliance Co. ; 89, Broad Street, Boston, U.S.A.) Dec. 22, 1932, No. 36367. [Class 51 (i).] In a furnace wall in which refractory blocks are individually supported on lugs projecting from spaced vertical supports, the lugs and co-operating recesses in the blocks are so formed that they are brought into engagement by a combined rearward and downward movement of the block with respect to its inner face. The vertical supports may be constituted by steam or water tubes 2, to which are welded inclined lugs 4, Fig. 5, adapted to support blocks a by engagement in recesses d having inclined upper walls. The blocks a may, as shown at 3, Fig. 3, be so shaped that they embrace and are wholly supported by a single tube 2, or blocks 5, Fig. 4, extending between and supported by a pair of adjacent tubes, may be employed. The inclined lugs 4 may be replaced by horizontal pins or by lugs 25, Fig. 12, arranged parallel to the tube and having their upper surface rounded and inclined downwardly towards the tube. In the latter construction, the wall is built up of half-blocks 26 having recesses 27 of the form shown in Fig. 15. Where portions of the tubes 2 are curved, the blocks 7, 8, Fig. 5, are similarly curved and are formed with upper and lower notches 9, 12 for engagement by pins 10, 13 on the tubes. Fig. 8 shows the invention applied to a locomotive firebox, the vertical supports in this case being constituted by wallplate flanges 16 having inclined lugs 17 engaging in similarly inclined notches d<11> in the blocks 20.

Title: New or improved process for the polymerziation of vinyl compounds
IPC: C08F2/02
Filed: 1934-12-21
Abstract: Polymerization products are manufactured by conjointly polymerizing vinyl esters of aliphatic acids and vinyl halides by means of a polymerization catalyst with agitation at temperatures below 60 DEG C., preferably below 40 DEG  C., in the absence of liquid media other than the vinyl compounds and in the presence of ferrous metals, viz. iron, steel, and alloy steels, e.g. containing nickel and chromium. In an example, a mixture of vinyl acetate and chloride is polymerized at 27--30 DEG  C. in the presence of acetyl benzoyl peroxide in an autoclave made of an austenitic alloy steel containing chromium and nickel, provided with an impeller agitator.  Other vinyl esters specified are the propionate, butyrate and formate.  Other suitable catalysts are other organic peroxides, e.g. dibenzoyl peroxide, if desired activated with organic acids or anhydrides, e.g. acetic acid or anhydride, and also lead tetraethyl.  Specification 406,338 is referred to.  The Specification as open to inspection under Sect. 91 comprises in general the polymerization of vinyl compounds with a catalyst in the absence of liquid media other than vinyl compounds and in the presence of materials which would tend, in the presence of liquid media, to inhibit the polymerization and to cause the formation of inferior polymerization products.  Reference is made to the polymerization of vinylbenzene, and to the polymerization of vinyl esters and halides alone.  This subject-matter does not appear in the Specification as accepted.
Patent GB-907105-A (GB)
Title: New polymers having azo-links
Inventor: HOLT PAUL FREDERICK
IPC: C08G73/00
Filed: 1958-11-14
Abstract: A polymer is prepared having a molecular structure containing a repeating unit comprising two benzene nuclei directly connected to each other and each carrying as a substituent the group -N=, adjacent units being connected together via the -N= groups by means of -N=N- linkages.  The -N= units and -N=N- linkages include <FORM:0907105/IV(a)/1> units and <FORM:0907105/IV(a)/2> linkages. The repeating units may be of the naphthalene or diphenyl types.  The polymers may be prepared by (a) oxidizing suitable compounds containing amine groups (b) reducing suitable compounds containing nitro groups or (c) treating a benzo (c) cinnoline with a hydrogen halide whereby the intramolecular -N=N- bonds are severed and adjacent benzo (c) cinnoline residues are linked together by the formation of intermolecular -N=N-linkages.  In the examples, the polymers are prepared by (1) reducing 4,5-dinitroacenaphthene with sodium hydroxide in ethanol (2) reducing 1:8-dinitronaphthalene with sodium sulphide in ethanol (3) reducing 2:6:21:61-tetranitrodiphenyl (a) with lithium aluminium hydride, (b) with sodium amalgam and ethanol and (c) with sodium sulphide and alkaline ethanol and (4) the reaction of 1:10-dimethyleneoxy (c) cinnoline with hydrobromic acid. In oxidizing suitable compounds containing amino groups, a suitable oxidizing agent is peracetic acid.  The polymers have a high degree of insolubility and are high temperature resistant which makes them suitable as plastic coatings for missiles and high speed aircraft and as linings for fire-bricks; they may be made to contain chelate rings and can therefore be used to separate small quantities of specific metals; they may also be used as dyestuffs as they are coloured.
