Title: Improvements relating to the treatment of lac or shellac
IPC: C08J3/03
Filed: 1938-05-16
Abstract: 515,000. Treatment of lac ; coating-compositions. SUTER, A. F., JANSER, A., and SUTER, W. E. May 16, 1938, No. 14531. [Classes 1 (i) and 95] A method of producing partial or total dispersion of lac or shellac in water consists in mechanically disintegrating the lac in the presence of the water until the lac has assumed partly or wholly a colloidal particle size, while maintaining a temperature below the softening point of the lac, and facilitating the dispersion by including in the water a wetting or dispersing agent in amount not sufficient to exert an appreciable dissolving action. Specified wetting or dispersing agents are sulphonated castor oil, tri-ethanolamine-lauryl-sulphonate, sodiumnaphthalene-sulphonate, ammonium linoleate, #-amino-ethylol-ricinoleate, ammonia, triethanolamine, ammonium sulpho-ricinoleate, and' alkali salts of shellac, partly hydrolysed shellac, or the oxyacids of shellac, such as the #-amino-ethylol compound of hydrolysed lac, and these may be used in conjunction with auxiliary dispersing agents such as linseed-oilfatty acids, glyceryl-mono-acetate, oleyl alcohol and ricinoleyl alcohol. Protective colloids such as methyl cellulose, gelatin, gum tragacanth, agar-agar, alkali caseinates and alginates are sometimes added. Organic solvents that possess a selective solvent power for the soft resinous lac portion, such As benzene and its homologues and tetra-hydro-naphthalene, may be added. These are readily emulsified and greatly promote the dispersion of the lac. If desired, the lac may be prepared, for' dispersion by the present process, by first dissolving it completely in an organic solvent or in an alkali, and precipitating it in a jelled or flocculent condition by means of water or an acid. The dispersions may be incorporated in coatings, paints, adhesives and mouldable materials, and the method of producing the dispersions is useful in separating the lac into hard and soft lac fractions, as the soft lac resin portion tends to disperse first and to assume a smaller particle size than the hard lac resin portion; and may, in consequence, be easily separated by filtration, especially if the dispersion is treated with an organic solvent having a selective solvent power for the soft, lac resin fraction. Drying oils, stand oils' and phenolaldehyde resins may be added and jointly emulsified, or rubber latex may be added after completion of the dispersion. Fillers, such as kaolin, and pigments may be incorporated. Examples are given. Specification 496,124. is referred to.
Patent GB-762143-A (GB)
Title: Monocrystalline strontium titanate
Inventor: MERKER LEON
IPC: C30B11/10
Filed: 1954-05-18
Abstract: A highly refractive monocrystalline mass consists of strontium titanate and up to 1 per cent of an oxidic compound of aluminium calculated as oxide, prepared in the form of a boule.  The boule may be prepared by introducing a powdered strontium titanate containing the aluminium oxide into an oxygen-hydrogen flame and crystallizing the melted material as a mono-crystalline mass in the form of a coloured boule which may subsequently be subjected to an oxidizing treatment at 650 to 700 DEG C. to produce a white boule.  The strontium titanate starting material may be prepared by reacting titanium oxalate with strontium chloride to precipitate strontium titanium oxalate which after washing may be heated to at least 500 DEG C. to form strontium titanate.  The colour of the boule produced depends on the quantity of oxide employed, and the boule may be cut and polished to form gems or lenses and prisms.  The refractive index of the material is 2.4 and the reciprocal dispersion is about 13. Specification 762,142 is referred to.

Title: Method of cleaning fabrics
IPC: D06L1/04
Filed: 1932-05-23
Abstract: In the cleaning of clothes and other fabrics by dry-cleaning solvent in which water is dispersed with the aid of an absorbefacient, the water is added to the solvent in an amount based on the weight and nature of the batch of clothes treated but not beyond the moisture tolerance thereof.  In an example, a batch of 50--60 lb. of clothes is dried, weighed, dipped in the hydrocarbon or chlorinated hydrocarbon solvent itself to remove the worst of the dirt and to saturate the fibres, and then treated in the usual manner in 50 gallons of solvent in which is dispersed 5--30 per cent of water relative to clothes according as to whether fine silk dresses or men's rough clothes are being treated.  For fine work the dispersion is preferably optically clear.  The cleaning liquid is preferably filtered during the cleaning process, and after use--maybe after distillation--the water-content is made up again.  Blending agents or absorbefacients specified are:--(1) 25 lb. of oleic acid, 25 lb. of naphtha, and 50 lb. of pure mahogany sodium sulphonate; a 6 per cent concentration in the oil is suitable.

Abstract: 626,016. Windscreen cleaners. TRICO PRODUCTS CORPORATION. June 5, 1947, No. 14921. Convention date, June 15, 1946. [Class 138(i)]  In a windscreen wiper for use on curved surfaces suspension links pivotally connected to a flexible wiping blade at spaced points are secured by a clip to the wiper operating arm. As shown in Fig. 1, the windscreen wiper blade 14 is supported from a clip 10 by suspension links 18 connected to mounting ears 22 of blade-supporting brackets 23. The clip is assembled on the end of the wiper-operating arm which comprises a blade-carrying section 3 pivoted to an oscillating member 2 and urged towards the windscreen 5 by a flat spring 6. The clip 10, Fig. 3, is hollow and formed of two complemental sections, each containing a rubber block 14 with arcuate grooves 9. The end of the blade-carrying section 3 is curved to fit the grooves 9 and has a lug 12 which interlocks with a divided keeper lug 11 carried by the clip sections. The suspension links 18 are fitted with their ends abutting in the tunnel 16 at the base of the clip. Lugs 17, fitting into corresponding cavities in the links, rigidly secure the links in the clip. The clip sections are fastened together by rivets passing through spacing sleeves 15. The suspension links are connected to the wiper blade as shown in Figs. 5 and 6. Hooks 20 at the outer ends of the suspension links 18 engage beneath the cross-bar 21 on mounting ears 22, the latter having flanges slidably embracing the wiper blade 19. Movement of the mounting ears along the wiper blade is prevented by lugs 24, provided on the hooked ends of the suspension arms, engaging with sockets 25 in the wiper blade. The sockets extend into a reinforcing member 26 of spring leaf construction, as shown in Fig. 2, which passes through a longitudinal orifice in the upper body of the wiper blade. The separate parts of the wiper are assembled by positioning the ears 22 over the sockets 25 of the wiper blade, inserting the hooked suspension arms 18 and swinging them downwards towards the blade so as to allow the lugs 24 to engage in the sockets 25. The ends of the suspension arms are then inserted in the clip and the assembly riveted together. The suspension arms are normally stiff and have little resilience, but to facilitate the detachment of the suspension arms from the wiper blade the arms may be made of a more resilient material. Specification 619,320 is referred to.
