Inventor: WRETE C
IPC: C11D11/00
Filed: 1965-02-18
Abstract: 1,142,152. Antiseptics containing boric acid and/or aluminium sub-acetate. C. M. A. WRETE. 17 Feb., 1966 [18 Feb., 1965], No. 6929/66. Heading A5E. [Also in Division D1] The skin irritating effect of a textile which ing with the alkaline surface active detergent is inhibited by treating the textile, after washing with the alkaline surface active detergent and mixing with an aqueous solution of basic aluminium sub-acetate and/or boric acid (provided that where only boric acid is used the aqueous solution contains as acid reacting substance monosodium citrate, tartaric acid, succinic acid, malic acid or fumaric acid) and completely or partly removing the solvent by evaporation so that a deposit of the basic aluminium sub-acetate and/or boric acid is formed in the textile. The textiles treated may be underclothes, shirts, sport-wear, sheets, pillow cases, handkerchiefs or towels and may be made from cotton. The basic aluminium sub-acetate and/or boric acid may be applied after washing the textiles with the alkaline detergent after the penultimate rinse, the textiles optionally being further rinsed and treated with further basic aluminium sub-acetate and/ or boric acid prior to wringing out or the use of a spin dryer.

Abstract: 1,017,799. Freezing apparatus. A. ESPER. SEN, A/S. April 29, 1964 [May 3, 1963], No. 17827/64. Heading F4H In freezing apparatus of the type comprising a plurality of freezing jackets connected at their upper ends to the compressor suction and discharge sides through shut-off valves and at their lower ends to a refrigerant reservoir, a closure member for the bottom of the space enclosed by the jacket is provided and is adapted to engage a portion of the inner wall of the jacket which is level with or above the point at which the connection is made to the refrigerant reservoir to ensure that the closure member is freed from frost when hot refrigerant is supplied to the jacket. As shown in Fig. 1 the top of a freezing jacket 4 is selectively connectible through a pressure-responsive valve 5 with either a refrigerant receiver 3 or a line 6 which communicates with the compressor discharge line 8 and includes a valve 7. The receiver normally receives liquid refrigerant from a condenser 10 and supplies it through a line 19 and valve 20 to the bottom of jacket 4, refrigerant vapour being returned to the receiver through valve 5 and thence to the compressor through line 2. The bottom of the jacket 4 is provided with a closure member 21 which as shown in Fig. 2 comprises a frusto-conical plug 24. The latter contacts the inner wall 4b of the jacket immediately above a lower downwardly divergent portion 4c of the wall, the pipe 19 being connected to the jacket at a point below the top of portion 4c. The plug 24 is mounted on a plate 26 hinged at 27 to a bracket 28, the free end 33 of the plate being engaged by an arm 32 of a pivoted lever the other arm of which carries a knob 35 and is connected to a bracket 30 by a spring 37. When hot refrigerant is supplied to the jacket 4 to release the frozen product, the knob 35 is depressed manually to cause arm 32 to move clear of plate 26 and rotate a bell-crank 61, 62 one arm of which bears against the upper surface of plate 26 to open the closure member to a limited extent. The knob is then released and the lever is rotated by,spring 37 in an anti-clockwise direction so that arm 32 causes the closure member to open further. Complete opening of the closure member is effected by the frozen product which is forced out of the jacket by a pneumatically operated piston 18 (Fig. 1), a pneumatic device 22, 23 being provided for returning member 21 to its closed position. Valve 20 in line 19 is closed by the passage therethrough of refrigerant vapour during the thawing period but has a by-pass passage therein to permit the passage of condensate from the jacket 4.

Abstract: Refractory articles are made by mixing a liquid composition comprising a zirconium ester of formula Zr(ORX)4 where R is C2-4 alkylene and X is Cl, Br or I and an aliphatic hydroxyamine containing up to 12 carbon atoms with water or a solution of water in a mutual solvent for water, the ester and the amine so as to cause the formation of a gel, adding to the liquid prior to gel formation a refractory powder such as zircon or alumina, shaping the resulting mixture, allowing to gel, and the shape to harden and then firing. Preferred amines are of type R1NHR2 where R1 is C2-4 hydroxyalkyl and R2 is hydrogen or C1-4 alkyl or hydroxy-alkyl. In examples, crucibles are made, firing temperatures being 1000 DEG  C. for zircon and at least 1400 DEG  C. for alumina.ALSO:The invention comprises zirconium esters of formula Zr(ORX)4 where R is C2- 4 alkylene and X is Cl, Br or I.  They are prepared by reacting ZrCl4, ZrBr4 or ZrI4 with a C2- 4 epoxy-alkane. An inert solvent may be used.  Compositions with aliphatic hydroxyamines may be hydrolysed to form gels (see Division C4) which may act as binders for refractory powders in making refractory articles (see Division C1).ALSO:Adhesive gel-forming compositions comprise a zirconium ester of formula Zr(ORX)4, where R is C2-4 alkylene and X is Cl, Br or I (for preparation see Division C2) and an aliphatic hydroxyamine containing up to 12 carbon atoms, the amount of the hydroxyamine being such that the composition is capable of forming a gel by hydrolysis.  Preferred amines are of the type R1NHR2, where R1 is C2-4 hydroxyalkyl and R2 is hydrogen or C1-4 alkyl or hydroxyalkyl. Gels may be formed by addition of water alone, but it may be necessary to use a solution of water in a mutual solvent for water, the ester and the amine, e.g. a lower aliphatic alcohol.  Some solvent may be included in the mixture of ester and amine.
