IPC: C03C8/10
Abstract: 683,544. Enamels. DU PONT DE NEMOURS & CO., E. I. Feb. 7, 1950 [April 13, 1949], No. 3143/50. Class 56. A vitreous enamel composition suitable for application to light metals and having a reduced tendency to " tear " comprises a frit comprising, in mol percentages, PbO 10-18, SiO, 38-65, Li 2 O5-12, Na 2 O 0-22, K 2 O 0-20, TiO 2  0-11, with an addition of 0.2-10 per cent of sodium silicate and 0.2-5 per cent of a group consisting of sodium and potassium metaborate based on the weight of the frit. The total alkali metal oxide content is 25-36 mol per cent and the ratio Si 1 O 2 +(2ÎTiO 2 )/alkalioxide is 1.8-3.0. The sodium silicate and alkali metal metaborate are preferably added as mill additions to the frit prior to grinding. The metaborate may be formed in situ in the enamel by adding boric acid or borax and sufficient sodium or potassium hydroxide to form the metaborate. The sodium silicate may be added in the form of water glass. The silicate and metaborate may be mixed together and with other mill additions such as ceramic pigments, dispersing agents, bonding agents, &c., before being added to the frit. Three examples are given showing the weight and mol percentages of the frit, these examples with the weight percentages of the frits are as follows:- (i) 20 parts KOH, 23 parts H 3 BO 3 , 43 parts white lead (2PbCO 3 -Pb(OH) 2  as dispersing agent, and 15 parts of aqueous water glass solution containing 63 per cent water and 37 per cent Na 2 O.4SiO 2  are mixed, and one part of the mixture added to 19 parts of the following frit, PbO 44.6, SiO 2  29.6, Li 2 O 2.3, Na 2 O 13.3, TiO 2  10.2 with 0-1.9 parts of inorganic pigment or opacifier. (ii) 35.4 parts KOH, 3.9 parts H 3 BO 3 , 25.6 parts water glass solution containing 63 per cent water are mixed and one part of the mixture is added to 12.5 parts of the following frit, PbO 37.4, SiO, 30.0, Li 2 O 2.3, Na 2 O 13.8, K 2 O 2.2, TiO 2  12.7, Sb 2 O 3  1.6, with 0.75 part of coloured inorganic pigment such as lead antimonate. (iii) 4.7 parts NaOH, 22.2 parts borax, 47 parts water glass solution containing 63 per cent water and 26.1 per cent Na 2 O.4SiO 2  are mixed and one part of the mixture is added to 4 parts of the following frit, PbO 34.2, SiO, 27.8, Li 2 O 2.4, Na 2 O 13.9, K 2 O 2.8, TiO, 13.7, Sb 2 O 3  2.8, BaO 2.4 with 0.4 part of coloured inorganic pigment or opacifier, e.g., TiO 2 . The mixtures when milled, applied by spraying, dried, and fired at 920-980 degrees F. are free from "tearing," "crawling," and "microtearing." Specifications 564,597 and 580,688 are referred to.
Patent GB-735310-A (GB)
Abstract: 735,310. Reinforced paper &c. CARLSON, A. E. June 30, 1952, No. 16417/52. Classes 96 and 140. In a reinforced thin flexible sheet-like material such as paper reinforced by a plurality of ribbon-like elements adhesively attached thereto, the reinforcing elements comprise a multiplicity of fine substantially continuous synthetic filaments grouped together in substantially parallel untwisted relation in the form of a thin compact ribbon and secured together by an adhesive. As shown in Fig. 4, reinforcing elements 14 formed of at least approximately 100 and preferably as many as 500 or more filaments of rayon, nylon, &c., are spaced about 4 to the inch over a sheet of paper and secured at the interface between the paper and the elements by coating the latter with adhesive preferably a non-asphaltic waterproof adhesive for example, one employing a synthetic resin or a latex-base adhesive, before bringing the element into contact with the paper and applying pressure to accelerate the bonding of the adhesive. The filaments may be dyed or colouring added to the adhesive to cause the colour of the element to blend with the paper. The thus reinforced sheet may be applied with a thin coating of adhesive to the joint of a paper carton with the re-inforcing element outwards as shown in Fig. 1 or inwards. In a modification (Fig. 5, not shown), paper sheets such as wrappings are provided with one set of spaced elements and a similar set extending transversely of the first set and of the same or different interval spacing. The sheet may be waterproofed, e.g. by a latexcoating applied either before or after the reinforcing elements are applied. As shown in Fig. 7, a paper bag formed from two-way reinforced paper which may or may not be waterproofed is provided with ventilating apertures between the reinforcing ribbons which provides an open or ventilated container for fruits, vegetables and the like. For flexible containers and bags of exceptional strength more than one layer of reinforced sheet paper may be used in which case the separate plies may not be bonded one to another while all or only some of the individual plies may bear the reinforcing elements. As shown in Fig. 8, a gummed tape is formed by applying the reinforcing elements lengthwise of the web of paper which is then slit into strips to form rolls 34 in which two or more reinforcing elements 36 are adhesively secured to the back or ungummed surface of the paper.

Abstract: 744,263. Roller weighting means. SOC. ALSACIENNE DE CONSTRUCTIONS MECANIQUES. June 15, 1953 [June 19, 1952], No. 16436/53. Class 120 (2). A roller weighting device for drawing rollers of textile spinning &c. machines comprises an arcuate saddle member bearing at one end against a support member and coupled at the other end to the shaft of a weighting roller, and means for applying a load to the saddle member, the arrangement being such that the saddle member is pulled down by the load and thereby exerts a pull between the support member and the shaft of the weighting roller causing the latter to bear against an adjacent roller. In the arrangement shown the saddle member consists of a hooked member 12 and a lever 15 connected by an articulated joint with an adjustable screw 12d between them. The member 12 is suspended from the shaft of weighting roller 13 and the lever 15 carries a stud 16 which bears against a member 17. A tie-rod 18 is connected to the articulated joint and is brought under tension by a spring 19. The bearing member 17 is arranged on a lever 20 secured on a shaft 21 to which is also secured a lever 22 acted upon by an adjustable screw 23. By means of this arrangement the pressure between the rollers can be adjusted and also the rollers can be unloaded completely by turning screw 23 until the stop 18a on the tie-rod 18 bears against the support means.
