Abstract: 1347859 Hydrogen peroxide DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 25 Aug 1971 [27 Aug 1970] 39918/71 Heading C1A An aqueous solution of hydrogen peroxide is obtained using the anthraquinone process by stripping the H 2 O 2  from the working solution of the oxidation stage of the process under reduced pressure, with the vapour of an organic solvent that is substantially immiscible with water, condensing the vapour to obtain an organic solution containing H 2 O 2  and extracting this H 2 O 2  by contacting the solution with a quantity of water such that an aqueous H 2 O 2  solution of desired concentration is formed. The organic solvent used is preferably such that the distribution coefficient for H 2 O 2  between water and the solvent is at least 5. Preferred solvents are one or more esters, ethers or ketones. The aqueous solution obtained may be purified and further concentrated by further distillation.

To maintain the guide surfaces 3 aligned with the gap 8 and the head-disc bearing 9 during machining, the guide is made from a one-piece casting, initially solid in the regions 11, 16, Fig. 2. The first turning operation at one setting consists of the surface 3 (continuous at this stage), the dowels 14 not yet being fitted, the bore for the bearing 9, and optionally the groove 11, Fig. 2, which defines the gap-sides 10. Three dowels 14 are then pressed into corre- / sponding flanges or lugs 6, 7 and the bearing 6 pressed in with a precision mandrel which is then used to locate the guide for machining away the portion 16 (and the portion 11, if not performed at the first setting), thus separating the surfaces 3. The surfaces 3 may be chromium-plated to resist wear.

Abstract: 1516687 Etching ENERGY CONVERSION DEVISES Inc 8 Oct 1975 [17 Oct 1974] 41268/75 Heading B6J [Also in Division G2] The tonal value of a dot image is corrected by ' lateral etching. The dots are prepared by exposing a film comprising a substrate 22, an opaque layer 24 and overlying photosensitive layer 26 to a dot image and then removing, using a solvent or mechanical means, areas of layer 26 and the underlying opaque layer 24 to leave the dots as shown in Fig. 6. The tonal value of the image is altered by further etching the dots to reduce the area they cover, however as their inner and outer faces are protected by the substrate and overlying layer their thick-  ness, and hence opacity, is not reduced, as  shown in Fig. 8. If during etching so much of the dot is removed that the overlying layer  touches the substrate, thus preventing further etching, the material can be exposed through the substrate. The dot prevents exposure of the portion of the layer immediately over it, whereas the excess portions are exposed and removed, thus permitting etching to continue.  The opaque layer comprises tellurium, molybdenum, polonium, cobalt, zinc, aluminium, copper, nickel, iron, tin, vanadium, germanium or silver or an alloy of any of the above. The etch solutions comprise aqueous solutions of sodium, potassium or lithium hypochlorite which can include sodium or potassium bicarbonate and alkali metal hydroxides.  Alternatively hydrogen peroxide, sodium or potassium chlorate together with a weak organic acid, e.g. citric acid, or ferric chloride may be used.

A three-dimensional pattern on a textile fabric shrinkable by the action of heat is formed by applying heat to the fabric to cause shrinkage thereof whilst protecting a pattern of selected areas of the fabric from heat with a liquid comprising water applied in the selected areas. The shrinkage causes the protected areas to buckle and lift. Preferably, the predetermined areas of the fabric are protected from heat by printing on the fabric a composition consisting of an aqueous solution of a thickening agent such as sodium polyacrylate, starch or methyl cellulose. The composition may be applied by an engraved roll rotating in a bath of the composition and wiped by a doctor blade so that the liquid is carried only in the engraving. The depth of the design may be varied by varying the depth of the engraving in the roll. Heat may be applied by passing the fabric continuously through an oven or by radiation from an electrically heated element. Specified fabrics are those made from, a linear polyester, e.g. polyethylene tarephthalate, a polymer or copolymer of vinyl chloride, polyethylene or polypropylene.
